These fish were collected to provide time- and site-dependent contaminant residue data needed by researchers and managers to fill critical data gaps regarding trends and behavior of persistent organic contaminants in the Great Lakes ecosystem. In the present study, data are presented for concentrations of several organochlorine (OC) contaminants in the archived smelt, including DDT, polychlorinated biphenyls (PCBs), toxaphene, and chlordanes in Lakes Michigan and Huron (MI, USA) and in Lake Superior (MN, USA). The trends for all the OCs were declining as a first-order decay over the sampled time series (1983/1985&ndash;1993/1999) with the exception of toxaphene in Lake Superior and PCBs at the Charlevoix/Little Traverse Bay site in Lake Michigan. Concentration of the emerging contaminant, polybrominated diphenyl ethers (PBDEs), also was traced from its apparent entry into this ecosystem in approximately 1980 until 1999. Time trends for the PBDEs were increasing exponentially at all sites, with concentration-doubling times varying from 1.58 to 2.94 years.</span></p>","language":"English","publisher":"Wiley","doi":"10.1897/04-390R.1","usgsCitation":"Chernyak, S.M., Rice, C.P., Quintal, R.T., Begnoche, L.J., Hickey, J.P., and Vinyard, B.T., 2005, Time trends (1983-1999) for organochlorines and polybrominated diphenyl ethers in rainbow smelt (<i>Osmerus mordax</i>) from Lakes Michigan, Huron and Superior, USA: Environmental Toxicology and Chemistry, v. 24, no. 7, p. 1632-1641, https://doi.org/10.1897/04-390R.1.","productDescription":"10 p.","startPage":"1632","endPage":"1641","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":128959,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"24","issue":"7","noUsgsAuthors":false,"publicationDate":"2005-07-01","publicationStatus":"PW","scienceBaseUri":"4f4e4a53e4b07f02db62b5ce","contributors":{"authors":[{"text":"Chernyak, Sergei M.","contributorId":98668,"corporation":false,"usgs":true,"family":"Chernyak","given":"Sergei","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":310280,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rice, Clifford P.","contributorId":56594,"corporation":false,"usgs":true,"family":"Rice","given":"Clifford","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":310278,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Quintal, Richard T. rquintal@usgs.gov","contributorId":4237,"corporation":false,"usgs":true,"family":"Quintal","given":"Richard","email":"rquintal@usgs.gov","middleInitial":"T.","affiliations":[],"preferred":true,"id":310276,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Begnoche, Linda J. lbegnoche@usgs.gov","contributorId":4236,"corporation":false,"usgs":true,"family":"Begnoche","given":"Linda","email":"lbegnoche@usgs.gov","middleInitial":"J.","affiliations":[],"preferred":true,"id":310275,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hickey, James P.","contributorId":83460,"corporation":false,"usgs":true,"family":"Hickey","given":"James","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":310279,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Vinyard, Bryan T.","contributorId":18709,"corporation":false,"usgs":true,"family":"Vinyard","given":"Bryan","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":310277,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Conservation and management of these species requires some understanding of how reproductive success is affected by edge effects, patch size, and characteristics of the landscape. We examined how differences in the percentage of grassland in the landscape influenced the relationships between the success of nests of upland-nesting ducks and (1) field size and (2) distance to nearest field and wetland edges. We collected data on study areas composed of 15–20% grassland and areas composed of 45–55% grassland in central North Dakota, USA during the 1996 and 1997 nesting seasons. Daily survival rates (DSRs) of duck nests were greater in study areas with 45–55% grassland than with 15–20% grassland. Within study areas, we detected a curvilinear relationship between DSR and field size: DSRs were highest in small and large fields and lowest in moderately sized fields. In study areas with 15–20% grassland, there was no relationship between probability of hatching and distance to nearest field edge, whereas in study areas with 45–55% grassland, there was a positive relationship between these two variables. Results of this study support the conclusion that both landscape composition and configuration affect reproductive success of ground-nesting birds. We are prompted to question conservation strategies that favor clustering moderately sized patches of nesting habitat within agricultural landscapes because our results show that such patches would have low nest success, most likely caused by predation. Understanding the pattern of nest success, and the predator–prey mechanisms that produce the pattern, will enable design of patch configurations that are most conducive to meeting conservation goals.</span></p>","language":"English","publisher":"Ecological Society of America","doi":"10.1890/03-5254","usgsCitation":"Horn, D.J., Phillips, M.L., Koford, R.R., Clark, W.R., Sovada, M.A., and Greenwood, R.J., 2005, Landscape composition, patch size, and distance to edges: Interactions affecting duck reproductive success: Ecological Applications, v. 15, no. 4, p. 1367-1376, https://doi.org/10.1890/03-5254.","productDescription":"10 p.","startPage":"1367","endPage":"1376","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":133731,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b20e4b07f02db6aba9b","contributors":{"authors":[{"text":"Horn, David Joseph","contributorId":174793,"corporation":false,"usgs":false,"family":"Horn","given":"David","email":"","middleInitial":"Joseph","affiliations":[],"preferred":false,"id":311751,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Phillips, Michael L.","contributorId":149855,"corporation":false,"usgs":false,"family":"Phillips","given":"Michael","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":311748,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Koford, Rolf R.","contributorId":16347,"corporation":false,"usgs":true,"family":"Koford","given":"Rolf","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":311746,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Clark, William R.","contributorId":174794,"corporation":false,"usgs":false,"family":"Clark","given":"William","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":311749,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Sovada, Marsha A. msovada@usgs.gov","contributorId":2601,"corporation":false,"usgs":true,"family":"Sovada","given":"Marsha","email":"msovada@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":311747,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Greenwood, Raymond J.","contributorId":174570,"corporation":false,"usgs":false,"family":"Greenwood","given":"Raymond","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":311750,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

We performed laboratory analysis of archived samples of Hexagenia spp. nymphs collected in 1985 and 1986 to provide base-line data on the distribution (1985) and seasonal infestation (1986) of the trematode parasite Crepidostomum spp. in Hexagenia spp. nymphs in connecting rivers between Lakes Superior and Erie of the Laurentian Great Lakes. In May and June 1985, frequency of occurrence of metacercariae was widely distributed throughout the connecting rivers (63% of 203 stations with nymphs), except in areas where nymph densities were relatively low (i.e.,a?Y69 nymphs/mA?). Distribution was probably underestimated in the present study because of low probability (mean = 31%, range = 0-57%) of detecting infestation in a small number of collected nymphs (a??10) at nymph densities a??69/mA?. In 1986, seasonal infestation between April and October occurred in 3.3% (627) of 18696 nymphs. Overall prevalence, mean intensity, and mean abundance of parasites at one station in the St. Marys River indicate parasite transmission occurred between June and September. This period of transmission is dependent on the life-cycle of the parasite. In addition, the life-cycle of Hexagenia spp. determines which annual cohort of nymphs is infested and therefore, the duration of infestation. Although, no impacts of infestation on Hexagenia spp. nymphs were observed in the present study, infestation intensities were high enough (a?Y25 metacercariae per nymph) at one station in the St. Marys River to potentially cause tissue damage in a high proportion (53%) of infested nymphs.</p>","language":"English","publisher":"Springer","doi":"10.1007/s10750-005-4755-4","usgsCitation":"Schloesser, D.W., 2005, Distribution and seasonal abundance of trematode parasites (Trematoda: Allocreadiidae: <i>Crepidostomum</i> spp.) in burrowing mayfly nymphs (Ephemeroptera: Ephemeridae: <i>Hexagenia</i> spp.) from connecting rivers of the Laurentian Great Lakes: Hydrobiologia, v. 548, no. 1, p. 177-189, https://doi.org/10.1007/s10750-005-4755-4.","productDescription":"13 p.","startPage":"177","endPage":"189","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133147,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"548","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a80e4b07f02db649619","contributors":{"authors":[{"text":"Schloesser, Don W.","contributorId":21485,"corporation":false,"usgs":true,"family":"Schloesser","given":"Don","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":310377,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Macroinvertebrate count data often exhibit nested or hierarchical structure. Examples include multiple measurements along each of a set of streams, and multiple synoptic measurements from each of a set of ponds. With data exhibiting hierarchical structure, outcomes at both sampling (e.g. within stream) and aggregated (e.g. stream) scales are often of interest. Unfortunately, methods for modelling hierarchical count data have received little attention in the ecological literature.</p><p>2. We demonstrate the use of hierarchical count models using fingernail clam (Family: Sphaeriidae) count data and habitat predictors derived from sampling and aggregated spatial scales. The sampling scale corresponded to that of a standard Ponar grab (0.052 m<sup>2</sup>) and the aggregated scale to impounded and backwater regions within 38–197 km reaches of the Upper Mississippi River. Impounded and backwater regions were resampled annually for 10 years. Consequently, measurements on clams were nested within years. Counts were treated as negative binomial random variates, and means from each resampling event as random departures from the impounded and backwater region grand means.</p><p>3. Clam models were improved by the addition of covariates that varied at both the sampling and regional scales. Substrate composition varied at the sampling scale and was associated with model improvements, and reductions (for a given mean) in variance at the sampling scale. Inorganic suspended solids (ISS) levels, measured in the summer preceding sampling, also yielded model improvements and were associated with reductions in variances at the regional rather than sampling scales. ISS levels were negatively associated with mean clam counts.</p><p>4. Hierarchical models allow hierarchically structured data to be modelled without ignoring information specific to levels of the hierarchy. In addition, information at each hierarchical level may be modelled as functions of covariates that themselves vary by and within levels. As a result, hierarchical models provide researchers and resource managers with a method for modelling hierarchical data that explicitly recognises both the sampling design and the information contained in the corresponding data.</p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1365-2427.2005.01350.x","usgsCitation":"Gray, B.R., Haro, R.J., Rogala, J.T., and Sauer, J.S., 2005, Modelling habitat associations with fingernail clam (Family: Sphaeriidae) counts at multiple spatial scales using hierarchical count models: Freshwater Biology, v. 50, no. 4, p. 715-729, https://doi.org/10.1111/j.1365-2427.2005.01350.x.","productDescription":"15 p.","startPage":"715","endPage":"729","numberOfPages":"15","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":506069,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1365-2427.2005.01350.x","text":"Publisher Index Page"},{"id":133982,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Illinois, Iowa, Minnesota, Wisconsin","otherGeospatial":"upper Mississippi River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -90.274658203125,\n              41.89409955811395\n            ],\n            [\n              -89.967041015625,\n              41.9921602333763\n            ],\n            [\n              -90.32958984375,\n              42.44778143462245\n            ],\n            [\n              -90.648193359375,\n              42.73894375124377\n            ],\n            [\n              -91.01074218749999,\n              42.924251753870685\n            ],\n            [\n              -90.966796875,\n              43.35713822211053\n            ],\n            [\n              -91.153564453125,\n              43.89789239125797\n            ],\n            [\n              -92.076416015625,\n              44.55133484083592\n            ],\n            [\n              -92.911376953125,\n              44.91035917458495\n            ],\n            [\n              -93.0322265625,\n              44.73892994307368\n            ],\n            [\n              -91.944580078125,\n              44.14279782818058\n            ],\n            [\n              -91.40625,\n              43.739352079154706\n            ],\n            [\n              -91.373291015625,\n              43.15710884095329\n            ],\n            [\n              -91.219482421875,\n              42.633958722673135\n            ],\n            [\n              -90.670166015625,\n              42.27730877423709\n            ],\n            [\n              -90.274658203125,\n              41.89409955811395\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"50","issue":"4","noUsgsAuthors":false,"publicationDate":"2005-03-18","publicationStatus":"PW","scienceBaseUri":"4f4e4a2ce4b07f02db613e82","contributors":{"authors":[{"text":"Gray, Brian R. 0000-0001-7682-9550 brgray@usgs.gov","orcid":"https://orcid.org/0000-0001-7682-9550","contributorId":2615,"corporation":false,"usgs":true,"family":"Gray","given":"Brian","email":"brgray@usgs.gov","middleInitial":"R.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":312451,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Haro, Roger J.","contributorId":12813,"corporation":false,"usgs":true,"family":"Haro","given":"Roger","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":312450,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rogala, James T. 0000-0002-1954-4097 jrogala@usgs.gov","orcid":"https://orcid.org/0000-0002-1954-4097","contributorId":2651,"corporation":false,"usgs":true,"family":"Rogala","given":"James","email":"jrogala@usgs.gov","middleInitial":"T.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":312452,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sauer, Jennifer S. 0000-0002-1563-1425 jsauer@usgs.gov","orcid":"https://orcid.org/0000-0002-1563-1425","contributorId":609,"corporation":false,"usgs":true,"family":"Sauer","given":"Jennifer","email":"jsauer@usgs.gov","middleInitial":"S.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":312453,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Our best model for reproductive rate included an interaction between a cyclic, annual time trend and male breeding experience, with higher reproductive rates in even years compared to odd, particularly for males with previous breeding experience. Reproductive rate was also negatively related to the amount of winter precipitation and positively related to the proportion of old-growth forest near the owl territory center. Apparent survival was not associated with age, sex, climate or any of the intermediate-aged forest types, but was positively associated with the proportion of older forest near the territory center in a pseudothreshold pattern. The quadratic structure of the proportion of nonhabitat farther from the nest or primary roost site was also part of our best survival model. Survival decreased dramatically when the amount of nonhabitat exceeded ∼50%. Habitat fitness potential estimates (λ̂<sub><i>h</i></sub>) for 97 owl territories ranged from 0.29–1.09, with a mean of 0.86 ± 0.02.

Studies of spotted owl site occupancy have used various binary response measures, but most of these studies have made the assumption that detectability is perfect, or at least high and not variable. Further, previous studies did not consider temporal variation in site occupancy. We used relatively new methods for open population modeling of site occupancy that incorporated imperfect and variable detectability of spotted owls and allowed modeling of temporal variation in site occupancy, extinction, and colonization probabilities. We also examined the effects of barred owl (<i>S. varia</i>) presence on these parameters. We used spotted owl survey data from 1990 to 2002 for 3 study areas in Oregon, USA, and we used program MARK to develop and analyze site occupancy models. We found per visit detection probabilities averaged &lt;0.70 and were highly variable among study years and study areas. Site occupancy probabilities for owl pairs declined greatly on 1 study area and slightly on the other 2 areas. For all owls, including singles and pairs, site occupancy was mostly stable through time. Barred owl presence had a negative effect on spotted owl detection probabilities, and it had either a positive effect on local-extinction probabilities or a negative effect on colonization probabilities. We conclude that further analyses of spotted owls must account for imperfect and variable detectability and barred owl presence to properly interpret results. Further, because barred owl presence is increasing within the range of northern spotted owls, we expect to see further declines in the proportion of sites occupied by spotted owls.</p>","language":"English","publisher":"The Wildlife Society","doi":"10.2193/0022-541X(2005)069[0918:MOSODF]2.0.CO;2","usgsCitation":"Olson, G.S., Anthony, R., Forsman, E.D., Ackers, S.H., Loschl, P.J., Reid, J.A., Dugger, K.M., Glenn, E., and Ripple, W.J., 2005, Modeling of site occupancy dynamics for northern spotted owls, with emphasis on the effects of barred owls: Journal of Wildlife Management, v. 69, no. 3, p. 918-932, https://doi.org/10.2193/0022-541X(2005)069[0918:MOSODF]2.0.CO;2.","productDescription":"15 p.","startPage":"918","endPage":"932","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":349093,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"69","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5a611696e4b06e28e9c258eb","contributors":{"authors":[{"text":"Olson, Gail S.","contributorId":19884,"corporation":false,"usgs":true,"family":"Olson","given":"Gail","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":722762,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Anthony, Robert G.","contributorId":61324,"corporation":false,"usgs":true,"family":"Anthony","given":"Robert G.","affiliations":[],"preferred":false,"id":722763,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Forsman, Eric D.","contributorId":96792,"corporation":false,"usgs":false,"family":"Forsman","given":"Eric","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":722764,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ackers, Steven H.","contributorId":36065,"corporation":false,"usgs":true,"family":"Ackers","given":"Steven","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":722765,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Loschl, Peter J.","contributorId":7195,"corporation":false,"usgs":true,"family":"Loschl","given":"Peter","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":722766,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Reid, Janice A.","contributorId":98034,"corporation":false,"usgs":true,"family":"Reid","given":"Janice","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":722767,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Dugger, Katie M. 0000-0002-4148-246X","orcid":"https://orcid.org/0000-0002-4148-246X","contributorId":36037,"corporation":false,"usgs":true,"family":"Dugger","given":"Katie","email":"","middleInitial":"M.","affiliations":[{"id":517,"text":"Oregon Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"preferred":false,"id":722768,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Glenn, Elizabeth M.","contributorId":96568,"corporation":false,"usgs":true,"family":"Glenn","given":"Elizabeth M.","affiliations":[],"preferred":false,"id":722769,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Ripple, William J.","contributorId":24271,"corporation":false,"usgs":true,"family":"Ripple","given":"William","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":722770,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

To address this need, the U.S. Geological Survey (USGS) has developed the Modular Modeling System (MMS). MMS is an integrated system of computer software for model development, integration, and application. Its modular design allows a high level of flexibility and adaptability to enable modelers to incorporate their own software into a rich array of built-in models and modeling tools. These include individual process models, tightly coupled models, loosely coupled models, and fully- integrated decision support systems. A geographic information system (GIS) interface, the USGS GIS Weasel, has been integrated with MMS to enable spatial delineation and characterization of basin and ecosystem features, and to provide objective parameter-estimation methods for models using available digital data. MMS provides optimization and sensitivity-analysis tools to analyze model parameters and evaluate the extent to which uncertainty in model parameters affects uncertainty in simulation results. MMS has been coupled with the Bureau of Reclamation object-oriented reservoir and river-system modeling framework, RiverWare, to develop models to evaluate and apply optimal resource-allocation and management strategies to complex, operational decisions on multipurpose reservoir systems and watersheds. This decision support system approach has been developed, tested, and implemented in the Gunnison, Yakima, San Joaquin, Rio Grande, and Truckee River basins of the western United States. MMS is currently being coupled with the U.S. Forest Service model SIMulating Patterns and Processes at Landscape Scales (SIMPPLLE) to assess the effects of alternative vegetation-management strategies on a variety of hydrological and ecological responses. Initial development and testing of the MMS-SIMPPLLE integration is being conducted on the Colorado Plateau region of the western United Sates.","largerWorkTitle":"Proceedings of the 2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges","conferenceTitle":"2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges","conferenceDate":"19 July 2005 through 22 July 2005","conferenceLocation":"Williamsburg, VA","language":"English","isbn":"0784407630","usgsCitation":"Leavesley, G., Markstrom, S., Viger, R., and Hay, L., 2005, The Modular Modeling System (MMS): A toolbox for water- and environmental-resources management, <i>in</i> Proceedings of the 2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges, Williamsburg, VA, 19 July 2005 through 22 July 2005, p. 435-436.","startPage":"435","endPage":"436","numberOfPages":"2","costCenters":[],"links":[{"id":238378,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba7fae4b08c986b32191d","contributors":{"editors":[{"text":"Moglen G.E.","contributorId":128404,"corporation":true,"usgs":false,"organization":"Moglen G.E.","id":536617,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Leavesley, G.H.","contributorId":93895,"corporation":false,"usgs":true,"family":"Leavesley","given":"G.H.","email":"","affiliations":[],"preferred":false,"id":414147,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Markstrom, S.L.","contributorId":76807,"corporation":false,"usgs":true,"family":"Markstrom","given":"S.L.","email":"","affiliations":[],"preferred":false,"id":414145,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Viger, Roland J. 0000-0003-2520-714X","orcid":"https://orcid.org/0000-0003-2520-714X","contributorId":80711,"corporation":false,"usgs":true,"family":"Viger","given":"Roland J.","affiliations":[],"preferred":false,"id":414146,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hay, L.E.","contributorId":54253,"corporation":false,"usgs":true,"family":"Hay","given":"L.E.","email":"","affiliations":[],"preferred":false,"id":414144,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The objectives of this study were to assess the population structure and gene flow patterns among migratory sandhill cranes using microsatellite DNA genotypes and mitochondrial DNA haplotypes of a large sample of individuals across three populations. In particular, we were interested in evaluating the roles of Pleistocene glaciation events and postglaciation gene flow in shaping the present-day population structure. Our results indicate substantial gene flow across regions of the Midcontinental population that are geographically adjacent, suggesting that gene flow for most of the region follows an isolation-by-distance model. Male-mediated gene flow and strong female philopatry may explain the differing patterns of nuclear and mitochondrial variation. Taken in context with precise geographical information on breeding locations, the morphologic and microsatellite DNA variation shows a gradation from the Arctic-nesting subspecies G. c. canadensis to the non-Arctic subspecies G. c. tabida. Analogous to other Arctic-nesting birds, it is probable that the population structure seen in Midcontinental sandhill cranes reflects the result of post-glacial secondary contact. Our data suggest that subspecies of migratory sandhills experience significant gene flow and therefore do not represent distinct and independent genetic entities. ??2005 Blackwell Publishing Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Molecular Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-294X.2005.02622.x","issn":"09621083","usgsCitation":"Jones, K., Krapu, G., Brandt, D., and Ashley, M., 2005, Population genetic structure in migratory sandhill cranes and the role of Pleistocene glaciations: Molecular Ecology, v. 14, no. 9, p. 2645-2657, https://doi.org/10.1111/j.1365-294X.2005.02622.x.","productDescription":"13 p.","startPage":"2645","endPage":"2657","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":240133,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212619,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-294X.2005.02622.x"}],"volume":"14","issue":"9","noUsgsAuthors":false,"publicationDate":"2005-06-13","publicationStatus":"PW","scienceBaseUri":"505a7d73e4b0c8380cd79f5f","contributors":{"authors":[{"text":"Jones, K.L.","contributorId":102024,"corporation":false,"usgs":true,"family":"Jones","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":431305,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Krapu, Gary L.","contributorId":56994,"corporation":false,"usgs":true,"family":"Krapu","given":"Gary L.","affiliations":[],"preferred":false,"id":431303,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brandt, D.A.","contributorId":67448,"corporation":false,"usgs":true,"family":"Brandt","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":431304,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ashley, M.V.","contributorId":15556,"corporation":false,"usgs":true,"family":"Ashley","given":"M.V.","email":"","affiliations":[],"preferred":false,"id":431302,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Adults of both sexes were collected during the autumn of 2002 in South Africa, and stereological analytical techniques were used to quantify the distribution of testicular cell types. In addition, total laryngeal mass was used as a gauge of secondary sex differences in animals from MGA and NMGA study sites. Evaluation of the total laryngeal mass revealed that there were no statistically significant differences between X. laevis of the same sex from the NMGA and MGA sites. Mean percent fractional-volume values for seminiferous tubule distribution of testicular cell types of mature X. laevis, ranged from 3-4% for spermatogonia, 26-28% for spermatocytes, 54-57% for spermatozoa, and 14-15% for other cells types. The mean percent volume for blood vessels ranged from 0.3-0.4%. These values did not differ significantly between frogs from NMGA and MGA areas. Collectively, these data demonstrated no differences in gonadal and laryngeal development in X. laevis collected in South Africa from MGA and NMGA areas and that there is little evidence for an effect of agricultural chemicals used in maize production functioning as endocrine disrupters in this species.

The fault varies in strike from northwest to west. In its westernmost section, the fault is ∼500 m south of an abrupt, curvilinear mountain front separating the 270- to 361-m-high La Cadena de San Francisco range from the Rio Añasco alluvial valley. The Quaternary fault of the Añasco Valley is in alignment with the bedrock fault mapped by D. McIntyre (1971) in the Central La Plata quadrangle sheet east of Añasco Valley. Previous workers have postulated that the Cerro Goden fault zone continues southeast from the Añasco Valley and merges with the Great Southern Puerto Rico fault zone of south-central Puerto Rico. West of the Añasco Valley, the fault continues offshore into the Mona Passage (Caribbean Sea) where it is characterized by offsets of seafloor sediments estimated to be of late Quaternary age. Using both 1:18,500 scale air photographs taken in 1936 and 1:40,000 scale photographs taken by the U.S. Department of Agriculture in 1986, we identified geomorphic features suggestive of Quaternary fault movement in the Añasco Valley, including aligned and deflected drainages, apparently offset terrace risers, and mountain-facing scarps. Many of these features suggest right-lateral displacement.</p><p>Mapping of Paleogene bedrock units in the uplifted La Cadena range adjacent to the Cerro Goden fault zone reveals the main tectonic events that have culminated in late Quaternary normal-oblique displacement across the Cerro Goden fault. Cretaceous to Eocene rocks of the La Cadena range exhibit large folds with wavelengths of several kms. The orientation of folds and analysis of fault striations within the folds indicate that the folds formed by northeast-southwest shortening in present-day geographic coordinates. The age of deformation is well constrained as late Eocene–early Oligocene by an angular unconformity separating folded, deep-marine middle Eocene rocks from transgressive, shallow-marine rocks of middle-upper Oligocene age. Rocks of middle Oligocene–early Pliocene age above unconformity are gently folded about the roughly east-west–trending Puerto Rico–Virgin Islands arch, which is well expressed in the geomorphology of western Puerto Rico. Arching appears ongoing because onshore and offshore late Quaternary oblique-slip faults closely parallel the complexly deformed crest of the arch and appear to be related to extensional strains focused in the crest of the arch. We estimate ∼4 km of vertical throw on the Cerro Goden fault based on the position of the carbonate cap north of the fault in the La Cadena de San Francisco and its position south of the fault inferred from seismic reflection data in Mayaguez Bay. Based on these observations, our interpretation of the kinematics and history of the Cerro Goden fault zone includes two major phases of motion: (1) Eocene northeast-southwest shortening possibly accompanied by left-lateral shearing as determined by previous workers on the Great Southern Puerto Rico fault zone; and (2) post–early Pliocene regional arching of Puerto Rico accompanied by normal offset and right-lateral shear along faults flanking the crest of the arch. The second phase of deformation accompanied east-west opening of the Mona rift and is inferred to continue to the present day.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0-8137-2385-X.115","usgsCitation":"Mann, P., Prentice, C., Hippolyte, J., Grindlay, N., Abrams, L., and Lao-Davila, D., 2005, Reconnaissance study of late quaternary faulting along Cerro Goden fault zone, western Puerto Rico: Special Paper of the Geological Society of America, v. 385, p. 115-137, https://doi.org/10.1130/0-8137-2385-X.115.","productDescription":"23 p.","startPage":"115","endPage":"137","numberOfPages":"23","costCenters":[],"links":[{"id":243175,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Puerto Rico","otherGeospatial":"Cerro Goden fault zone","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -67.3187255859375,\n              17.926475979176438\n            ],\n            [\n              -66.33270263671875,\n              17.926475979176438\n            ],\n            [\n              -66.33270263671875,\n              18.521283325496277\n            ],\n            [\n              -67.3187255859375,\n              18.521283325496277\n            ],\n            [\n              -67.3187255859375,\n              17.926475979176438\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"385","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9913e4b0c8380cd82d6f","contributors":{"authors":[{"text":"Mann, P.","contributorId":55167,"corporation":false,"usgs":true,"family":"Mann","given":"P.","email":"","affiliations":[],"preferred":false,"id":450576,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Prentice, C.S.","contributorId":56667,"corporation":false,"usgs":true,"family":"Prentice","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":450577,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hippolyte, J.-C.","contributorId":36377,"corporation":false,"usgs":true,"family":"Hippolyte","given":"J.-C.","email":"","affiliations":[],"preferred":false,"id":450574,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Grindlay, N.R.","contributorId":28445,"corporation":false,"usgs":true,"family":"Grindlay","given":"N.R.","email":"","affiliations":[],"preferred":false,"id":450573,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Abrams, L.J.","contributorId":98968,"corporation":false,"usgs":true,"family":"Abrams","given":"L.J.","email":"","affiliations":[],"preferred":false,"id":450578,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Lao-Davila, D.","contributorId":44753,"corporation":false,"usgs":true,"family":"Lao-Davila","given":"D.","email":"","affiliations":[],"preferred":false,"id":450575,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

That is, although conduits likely are present, the assumption is that flow in the aquifer predominantly is through a network of small fractures and openings sufficiently numerous that the aquifer can be considered a porous-media continuum at the regional scale. Whether flow through large fractures and conduits or diffuse flow predominates in the Edwards aquifer at the regional scale is an open question. A new numerical ground-water-flow model (Edwards aquifer model) that incorporates important components of the latest information and an alternate conceptualization of the Edwards aquifer was developed. The conceptualization upon which the Edwards aquifer model is based emphasizes conduit development and conduit flow, and the model can be considered a test of one of two reasonable conceptualizations. The model incorporates conduits simulated as generally continuously connected, one-cell-wide (1,320 feet) zones with very large hydraulic-conductivity values (as much as 300,000 feet per day). The locations of the conduits are based on a number of factors, including major potentiometric-surface troughs in the aquifer, the presence of sinking streams, geochemical information, and geologic structures (for example, faults and grabens). The model includes both the San Antonio and Barton Springs segments of the Edwards aquifer in the San Antonio region, Texas, and was calibrated for steady-state (1939-46) and transient (1947-2000) conditions. Transient simulations were conducted using monthly recharge and pumpage (withdrawals) data. The predominantly conduit-flow conceptualization incorporated in the Edwards aquifer model yielded a reasonably good match between measured and simulated hydraulic heads in the confined part of the aquifer and between measured and simulated springflows. The simulated directions of flow in the Edwards aquifer model are most strongly influenced by the presence of simulated conduits and barrier faults. The simulated flow in the Edwards aquifer is appreciably influenced by the locations of the simulated conduits, which tend to facilitate flow. The simulated subregional flow directions generally are toward the nearest conduit and subsequently along the conduits from the recharge zone into the confined zone and toward the major springs. Structures simulated in the Edwards aquifer model that tend to restrict ground-water flow are barrier faults. The influence of simulated barrier faults on flow directions is most evident in northern Medina County.","largerWorkTitle":"Geotechnical Special Publication","conferenceTitle":"10th Multidisciplinary Conference - Sinkholes and the Engineering and Environmental Impacts of Karst","conferenceDate":"24 September 2005 through 28 September 2005","conferenceLocation":"San Antonio, TX","language":"English","issn":"08950563","usgsCitation":"Lindgren, K., Dutton, A., Hovorka, S., Worthington, S., and Painter, S., 2005, Conceptualization and simulation of the Edwards aquifer, San Antonio region, Texas, <i>in</i> Geotechnical Special Publication, no. 144, San Antonio, TX, 24 September 2005 through 28 September 2005, p. 122-130.","startPage":"122","endPage":"130","numberOfPages":"9","costCenters":[],"links":[{"id":238171,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"144","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f9ade4b0c8380cd4d70e","contributors":{"editors":[{"text":"Beck B.F.","contributorId":128361,"corporation":true,"usgs":false,"organization":"Beck B.F.","id":536626,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Lindgren, K.J.","contributorId":68958,"corporation":false,"usgs":true,"family":"Lindgren","given":"K.J.","email":"","affiliations":[],"preferred":false,"id":414587,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dutton, A.R.","contributorId":93976,"corporation":false,"usgs":true,"family":"Dutton","given":"A.R.","email":"","affiliations":[],"preferred":false,"id":414589,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hovorka, S.D.","contributorId":71259,"corporation":false,"usgs":true,"family":"Hovorka","given":"S.D.","email":"","affiliations":[],"preferred":false,"id":414588,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Worthington, S.R.H.","contributorId":55522,"corporation":false,"usgs":true,"family":"Worthington","given":"S.R.H.","email":"","affiliations":[],"preferred":false,"id":414586,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Painter, S.","contributorId":28799,"corporation":false,"usgs":true,"family":"Painter","given":"S.","affiliations":[],"preferred":false,"id":414585,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The concept is especially valuable in subjective assessments of future coal production, which would require a detailed understanding of the coal geology and coal chemistry of the region. In addition, subjective assessments of future coal production would be enhanced by a geographical information system that contains the geologic and geochemical data commonly prepared for conventional coal assessments. Coal systems are generally defined as one or more coal beds or groups of coal beds that have had the same or similar genetic history from their inception as peat deposits, through their burial, diagenesis, and epigenesis to their ultimate preservation as lignite, bituminous coal, or anthracite. The central and northern parts of the Appalachian basin contain seven coal systems (Coal Systems A-G). These systems may be defined generally on the following criteria: (1) on the primary characteristics of their paleopeat deposits, (2) on the stratigraphic framework of the Paleozoic coal measures, (3) on the relative abundance of coal beds within the major stratigraphic groupings, (4) on the amount of sulfur related to the geologic and climatic conditions under which paleopeat deposits accumulated, and (5) on the rank of the coal (lignite to anthracite). ??2005 Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Special Paper of the Geological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/0-8137-2387-6.9","issn":"00721077","usgsCitation":"Milici, R.C., 2005, Appalachian coal assessment: Defining the coal systems of the Appalachian basin: Special Paper of the Geological Society of America, no. 387, p. 9-30, https://doi.org/10.1130/0-8137-2387-6.9.","startPage":"9","endPage":"30","numberOfPages":"22","costCenters":[],"links":[{"id":242934,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215156,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/0-8137-2387-6.9"}],"issue":"387","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ec76e4b0c8380cd492a6","contributors":{"authors":[{"text":"Milici, R.

In this paper we investigate temporal variability in hydrodynamic roughness using velocity profiles in the bottom boundary layer measured with a high-resolution acoustic Doppler profiler (PCADP). The data were collected on the ebb-tidal delta off Grays Harbor, Washington, in a mean water depth of 9 m. Significant wave height ranged from 0.5 to 3 m. Bottom roughness has rarely been determined from hydrodynamic measurements under conditions such as these, where energetic waves and medium-to-fine sand produce small bedforms. Friction velocity due to current u*c and apparent bottom roughness z0a were determined from the PCADP burst mean velocity profiles using the law of the wall. Bottom roughness kB was estimated by applying the Grant-Madsen model for wave-current interaction iteratively until the model u*c converged with values determined from the data. The resulting kB values ranged over 3 orders of magnitude (10-1 to 10-4 m) and varied inversely with wave orbital diameter. This range of kB influences predicted bottom shear stress considerably, suggesting that the use of time-varying bottom roughness could significantly improve the accuracy of sediment transport models. Bedform height was estimated from kB and is consistent with both ripple heights predicted by empirical models and bedforms in sonar images collected during the experiment.

Macroinvertebrate data often exhibit substantially larger variances than expected under a standard count assumption, that of the Poisson distribution. Such overdispersion may derive from multiple sources, including heterogeneity of habitat (historically and spatially), differing life histories for organisms collected within a single collection in space and time, and autocorrelation. Taken to extreme, heterogeneity of habitat may be argued to explain the frequent large proportions of zero observations in macroinvertebrate data. Sampling locations may consist of habitats defined qualitatively as either suitable or unsuitable. The former category may yield random or stochastic zeroes and the latter structural zeroes. Heterogeneity among counts may be accommodated by treating the count mean itself as a random variable, while extra zeroes may be accommodated using zero-modified count assumptions, including zero-inflated and two-stage (or hurdle) approaches. These and linear assumptions (following log- and square root-transformations) were evaluated using 9 years of mayfly density data from a 52 km, ninth-order reach of the Upper Mississippi River (n = 959). The data exhibited substantial overdispersion relative to that expected under a Poisson assumption (i.e. variance:mean ratio = 23 ??? 1), and 43% of the sampling locations yielded zero mayflies. Based on the Akaike Information Criterion (AIC), count models were improved most by treating the count mean as a random variable (via a Poisson-gamma distributional assumption) and secondarily by zero modification (i.e. improvements in AIC values = 9184 units and 47-48 units, respectively). Zeroes were underestimated by the Poisson, log-transform and square root-transform models, slightly by the standard negative binomial model but not by the zero-modified models (61%, 24%, 32%, 7%, and 0%, respectively). However, the zero-modified Poisson models underestimated small counts (1 ??? y ??? 4) and overestimated intermediate counts (7 ??? y ??? 23). Counts greater than zero were estimated well by zero-modified negative binomial models, while counts greater than one were also estimated well by the standard negative binomial model. Based on AIC and percent zero estimation criteria, the two-stage and zero-inflated models performed similarly. The above inferences were largely confirmed when the models were used to predict values from a separate, evaluation data set (n = 110). An exception was that, using the evaluation data set, the standard negative binomial model appeared superior to its zero-modified counterparts using the AIC (but not percent zero criteria). This and other evidence suggest that a negative binomial distributional assumption should be routinely considered when modelling benthic macroinvertebrate data from low flow environments. Whether negative binomial models should themselves be routinely examined for extra zeroes requires, from a statistical perspective, more investigation. However, this question may best be answered by ecological arguments that may be specific to the sampled species and locations. ?? 2004 Elsevier B.V.

The aim of this study is to investigate the effect of the seasonal distributions of water and energy, and their interactions with the soil moisture store, on mean annual water balance in Australia at catchment scales using a stochastic model of soil moisture balance with seasonally varying forcing. The rainfall regime at 262 catchments around Australia was modeled as a Poisson process with the mean storm arrival rate and the mean storm depth varying throughout the year as cosine curves with annual periods. The soil moisture dynamics were represented by use of a single, finite water store having infinite infiltration capacity, and the potential evapotranspiration rate was modeled as an annual cosine curve. The mean annual water budget was calculated numerically using a Monte Carlo simulation. The model predicted that for a given level of climatic aridity the ratio of mean annual evapotranspiration to rainfall was larger where the potential evapotranspiration and rainfall were in phase, that is, in summer‐dominant rainfall catchments, than where they were out of phase. The observed mean annual evapotranspiration ratios have opposite results. As a result, estimates of mean annual evapotranspiration from the model compared poorly with observational data. Because the inclusion of seasonally varying forcing alone was not sufficient to explain variability in the mean annual water balance, other catchment properties may play a role. Further analysis showed that the water balance was highly sensitive to the catchment‐scale soil moisture capacity. Calibrations of this parameter indicated that infiltration‐excess runoff might be an important process, especially for the summer‐dominant rainfall catchments; most similar studies have shown that modeling of infiltration‐excess runoff is not required at the mean annual timescale.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2004WR003697","usgsCitation":"Potter, N., Zhang, L., Milly, P., McMahon, T., and Jakeman, A., 2005, Effects of rainfall seasonality and soil moisture capacity on mean annual water balance for Australian catchments: Water Resources Research, v. 41, no. 6, Article W06007; 11 p., https://doi.org/10.1029/2004WR003697.","productDescription":"Article W06007; 11 p.","costCenters":[],"links":[{"id":497384,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://admin.research-repository.uwa.edu.au/en/publications/dd5131ba-913b-4ad7-aaa3-51e7f2c4b4a5","text":"External Repository"},{"id":239863,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"41","issue":"6","noUsgsAuthors":false,"publicationDate":"2005-06-09","publicationStatus":"PW","scienceBaseUri":"505a07a8e4b0c8380cd5177d","contributors":{"authors":[{"text":"Potter, N.J.","contributorId":9466,"corporation":false,"usgs":true,"family":"Potter","given":"N.J.","email":"","affiliations":[],"preferred":false,"id":432040,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zhang, L.","contributorId":41543,"corporation":false,"usgs":true,"family":"Zhang","given":"L.","email":"","affiliations":[],"preferred":false,"id":432042,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Milly, P.

Velocity-log data collected in five long-screened production wells in the Pleasant Valley area of southern California showed that (1) electromagnetic flowmeter results were comparable within ±2% to results obtained using an impeller flowmeter for comparable depths; (2) the measured velocities from the electromagnetic flowmeter were up to 36% greater than the published maximum range; and (3) both data sets, collected without the use of centralizers or flow diverters, produced comparable and interpretable results. Although either method is acceptable for measuring wellbore velocities and the distribution of flow, the electromagnetic flowmeter enables collection of data over a now greater range of flows. In addition, changes in fluid temperature and fluid resistivity, collected as part of the electromagnetic flowmeter log, are useful in the identification of flow and hydrogeologic interpretation.</span></p>","language":"English","publisher":"National Ground Water Association","doi":"10.1111/j.1745-6584.2005.0030.x","issn":"0017467X","usgsCitation":"Newhouse, M., Izbicki, J., and Smith, G., 2005, Comparison of velocity-log data collected using impeller and electromagnetic flowmeters: Ground Water, v. 43, no. 3, p. 434-438, https://doi.org/10.1111/j.1745-6584.2005.0030.x.","productDescription":"5 p.","startPage":"434","endPage":"438","numberOfPages":"5","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":239774,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"43","issue":"3","noUsgsAuthors":false,"publicationDate":"2005-05-09","publicationStatus":"PW","scienceBaseUri":"5059f8bce4b0c8380cd4d270","contributors":{"authors":[{"text":"Newhouse, M.W.","contributorId":65892,"corporation":false,"usgs":true,"family":"Newhouse","given":"M.W.","email":"","affiliations":[],"preferred":false,"id":432819,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Izbicki, J.

Data from uncontaminated forests were used to provide estimates of background mutation rates. We also determined whether other fitness parameters were negatively correlated with mutagenic stress (e.g., degree of outcrossing and numbers of reproducing trees km-1). Contaminated sites in Tampa Bay had significantly higher frequencies of trees that were heterozygous for albinism per 1000 total reproducing trees (FHT) than uncontaminated forests (mean ?? SE: 11.4 ?? 4.3 vs 4.3 ?? 0.73, P<0.022). Two sites that were contaminated by oil failed to show elevated FHT, although in the first instance, the mutagenic effects of the oil may have been reduced by several weeks of weathering in open water before coming ashore, and in the second > 25 yrs of subsequent recruitment and tree replacement may have allowed an initial elevation in the FHT to decay. Patterns of FHT were not explained by distance from the bay mouth or the degree of urbanization. However, there was a significant positive relationship between tree size and FHT (r=0.83, P<0.018), which suggests that forests with older or larger trees provide a more lasting record of cumulative mutagenic stress. No other fitness parameters correlated with FHT. There was a difference in FHT between two latitudes, as determined by comparing Tampa Bay with literature values for Puerto Rico. The sensitivity of this bioassay for the effects of mutagens will facilitate future monitoring of contamination events and comparisons of bay-wide recovery in future decades. Development of a database of FHT values for a range of subtropical and tropical estuaries is underway that will provide a baseline against which to compare mutational consequences of global change. ?? 2005, The Society of Wetland Scientists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1672/9","issn":"02775212","usgsCitation":"Proffitt, C., and Travis, S., 2005, Albino mutation rates in red mangroves (Rhizophora mangle L.) as a bioassay of contamination history in Tampa Bay, Florida, USA: Wetlands, v. 25, no. 2, p. 326-334, https://doi.org/10.1672/9.","startPage":"326","endPage":"334","numberOfPages":"9","costCenters":[],"links":[{"id":212246,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1672/9"},{"id":239706,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e955e4b0c8380cd481f3","contributors":{"authors":[{"text":"Proffitt, C.E. 0000-0002-0845-8441","orcid":"https://orcid.org/0000-0002-0845-8441","contributorId":47339,"corporation":false,"usgs":true,"family":"Proffitt","given":"C.E.","email":"","affiliations":[],"preferred":false,"id":432475,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Travis, S.E. 0000-0001-9338-8953","orcid":"https://orcid.org/0000-0001-9338-8953","contributorId":28718,"corporation":false,"usgs":true,"family":"Travis","given":"S.E.","email":"","affiliations":[],"preferred":false,"id":432474,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The presence of steep slopes in mountainous terrain, coupled with weathered soils and intense rainfall, leads to severe slope-stability problems throughout the island. Episodic triggering events such as hurricanes and earthquakes further exacerbate these problems. All physiographic provinces of the island have experienced landslides. The stability of natural and man-made slopes is a serious concern for government authorities and the civil engineering community in Puerto Rico. This paper presents an overview of the rainfall induced landslide problem in PR, a summary of literature published on this subject, and proposes a rainfall intensity landslide threshold based on landslide events data from 1959 to 2003. This threshold can be used as part of a potential landslide warning system.","largerWorkTitle":"Geotechnical Special Publication","conferenceTitle":"Geo-Frontiers 2005","conferenceDate":"24 January 2005 through 26 January 2005","conferenceLocation":"Austin, TX","language":"English","issn":"08950563","usgsCitation":"Pando, M., Ruiz, M., and Larsen, M.C., 2005, Rainfall-induced landslides in Puerto Rico: An overview, <i>in</i> Geotechnical Special Publication, no. 130-142, Austin, TX, 24 January 2005 through 26 January 2005, p. 2911-2925.","startPage":"2911","endPage":"2925","numberOfPages":"15","costCenters":[],"links":[{"id":239882,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"130-142","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9475e4b0c8380cd81407","contributors":{"authors":[{"text":"Pando, M.A.","contributorId":88953,"corporation":false,"usgs":true,"family":"Pando","given":"M.A.","email":"","affiliations":[],"preferred":false,"id":430836,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ruiz, M.E.","contributorId":52792,"corporation":false,"usgs":true,"family":"Ruiz","given":"M.E.","email":"","affiliations":[],"preferred":false,"id":430834,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Larsen, M.

Average pH values at the upstream (F1), middle (F2), and downstream (F3) monitoring stations were 3.31, 5.46, and 6.80, respectively. The downstream increase in pH resulted in precipitation of hydrous ferric oxide (HFO) and hydrous aluminum oxide (HAO) on the streambed. At F1 and F2, Fe showed strong diel cycles in dissolved concentration and Fe(II)/Fe(III) ratio; these cycles were attributed to daytime photoreduction of Fe(III) to Fe(II), reoxidation of Fe(II) to Fe(III), and temperature-dependent hydrolysis and precipitation of HFO. At the near-neutral downstream station, no evidence of Fe(III) photoreduction was observed, and suspended particles of HFO dominated the total Fe load. HFO precipitation rates between F2 and F3 were highest in the afternoon, due in part to reoxidation of a midday pulse of Fe<sup>2+</sup><span>&nbsp;</span>formed by photoreduction in the upper, acidic portions of the stream. Dissolved concentrations of Fe(II) and Cu decreased tenfold and 2.4-fold, respectively, during the day at F3. These changes were attributed to sorption onto fresh HFO surfaces. Results of surface complexation modeling showed good agreement between observed and predicted Cu concentrations at F3, but only when adsorption enthalpies were added to the thermodynamic database to take into account diel temperature variations. The field and modeling results illustrate that the degree to which trace metals adsorb onto actively forming HFO is strongly temperature dependent. This study is an example of how diel Fe cycles caused by redox and hydrolysis reactions can induce a diel cycle in a trace metal of toxicological importance in downstream waters.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/j.gca.2004.11.020","issn":"00167037","usgsCitation":"Gammons, C., Nimick, D., Parker, S., Cleasby, T., and McCleskey, R.B., 2005, Diel behavior of iron and other heavy metals in a mountain stream with acidic to neutral pH: Fisher Creek, Montana, USA: Geochimica et Cosmochimica Acta, v. 69, no. 10, p. 2505-2516, https://doi.org/10.1016/j.gca.2004.11.020.","productDescription":"12 p.","startPage":"2505","endPage":"2516","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":239737,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212275,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.gca.2004.11.020"}],"country":"United States","state":"Montana","otherGeospatial":"Fisher Creek","volume":"69","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a00bee4b0c8380cd4f8be","contributors":{"authors":[{"text":"Gammons, C.H.","contributorId":18459,"corporation":false,"usgs":true,"family":"Gammons","given":"C.H.","affiliations":[],"preferred":false,"id":432638,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nimick, D.

Utilizing Web-based technologies, the Colorado Geological Survey's Colorado Late Cenozoic Fault and Fold Database was transformed from a monothematic, nonspatial Microsoft Access database into a complex information set incorporating multiple data sources. The resulting user-friendly format supports easy analysis and browsing. The core of the application is the Microsoft Access database, which contains information compiled from available literature about faults and folds that are known or suspected to have moved during the late Cenozoic. The database contains nonspatial fields such as structure type, age, and rate of movement. Geographic locations of the fault and fold traces were compiled from previous studies at 1:250,000 scale to form a spatial database containing information such as length and strike. Integration of the two databases allowed both spatial and nonspatial information to be presented on the Internet as a single dataset (http://geosurvey.state.co.us/pubs/ceno/). The user-friendly interface enables users to view and query the data in an integrated manner, thus providing multiple ways to locate desired information. Retaining the digital data format also allows continuous data updating and quick delivery of newly acquired information. This dataset is a valuable resource to anyone interested in earthquake hazards and the activity of faults and folds in Colorado. Additional geologic hazard layers and imagery may aid in decision support and hazard evaluation.
