The dataset covered nearly three years, from October 1998 to June 2001, and included 160,000 observations. The objectives of the tagging were to obtain temperature data to refine bioenergetics models of sea lamprey (Petromyzon marinus) predation on lake trout, and compare the temperatures occupied by strains of lake trout stocked in Lake Huron. The seasonal, thermal-use profiles of lake trout followed the general warming and cooling pattern of Lake Huron. During periods when the zone of surface water mixing extended below the depth range occupied by lake trout, variability among individual fish and strains was low and followed surface temperature. However, during the period of summer stratification, the average temperatures occupied varied substantially among individual fish and strains. Strains originating from the upper Great Lakes (Lake Superior and Lewis Lake, WY) occupied similar temperatures. Between June and mid August, upper Great Lakes lake trout typically occupied water several degrees warmer than that occupied by lake trout of Finger Lakes, New York origin. Most of the lake trout occupied summer temperatures lower than the preferred temperatures suggested by laboratory studies. In October, all strains occupied water as warm or warmer than that occupied in summer, which may partially explain the higher lethality of sea lamprey attacks during October.</p>","language":"English","usgsCitation":"Bergstedt, R.A., Argyle, R.L., Seelye, J.G., Scribner, K.T., and Curtis, G.L., 2003, In situ determination of the annual thermal habitat use by lake trout (Salvelinus namaycush) in Lake Huron: Journal of Great Lakes Research, v. 29, p. 347-361.","productDescription":"15 p.","startPage":"347","endPage":"361","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133157,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49fce4b07f02db5f5904","contributors":{"authors":[{"text":"Bergstedt, Roger A. rbergstedt@usgs.gov","contributorId":4174,"corporation":false,"usgs":true,"family":"Bergstedt","given":"Roger","email":"rbergstedt@usgs.gov","middleInitial":"A.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":309564,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Argyle, Ray L.","contributorId":9993,"corporation":false,"usgs":true,"family":"Argyle","given":"Ray","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":309565,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Seelye, James G.","contributorId":69919,"corporation":false,"usgs":true,"family":"Seelye","given":"James","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":309567,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Scribner, Kim T.","contributorId":95434,"corporation":false,"usgs":false,"family":"Scribner","given":"Kim","email":"","middleInitial":"T.","affiliations":[{"id":6601,"text":"Michigan State University","active":true,"usgs":false}],"preferred":false,"id":309568,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Curtis, Gary L.","contributorId":16356,"corporation":false,"usgs":true,"family":"Curtis","given":"Gary","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":309566,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Fields planted with annual crops and pastures were used very little, except when they were cut for hay, plowed, and harvested, or when low crop height and cover allowed the hawks to land in fields. The availability of abundant, yet widely-spaced and transient food-sources, such as insect outbreaks, appeared to be the principal factor influencing habitat use by the hawks.

Best fit to the power model or exponential model was determined by comparing adjusted <i>r</i><sup>2</sup> values from the least squares regression, pattern of residuals, homoscedasticity across scales, and semi-log slopes at 1–100&nbsp;m<sup>2</sup> and 100–1000&nbsp;m<sup>2</sup>. Dominance–diversity curves were tested for fit to the lognormal model, MacArthur's broken stick model, and the geometric and harmonic series.</p><p><strong>Results</strong> Early successional Western Australia and California shrublands represented the extremes and provide an interesting contrast as the exponential model was the best fit for the former, and the power model for the latter, despite similar total species richness. We hypothesize that structural differences in these communities account for the different species–area curves and are tied to patterns of dominance, equitability and life form distribution. Dominance–diversity relationships for Western Australian heathlands exhibited a close fit to MacArthur's broken stick model, indicating more equitable distribution of species. In contrast, Californian shrublands, both postfire and mature stands, were best fit by the geometric model indicating strong dominance and many minor subordinate species. These regions differ in life form distribution, with annuals being a major component of diversity in early successional Californian shrublands although they are largely lacking in mature stands. Both young and old Australian heathlands are dominated by perennials, and annuals are largely absent. Inherent in all of these ecosystems is cyclical disequilibrium caused by periodic fires. The potential for community reassembly is greater in Californian shrublands where only a quarter of the flora resprout, whereas three quarters resprout in Australian heathlands.</p><p>Other Californian vegetation types sampled include coniferous forests, oak savannas and desert scrub, and demonstrate that different community structures may lead to a similar species–area relationship. Dominance–diversity relationships for coniferous forests closely follow a geometric model whereas associated oak savannas show a close fit to the lognormal model. However, for both communities, species–area curves fit a power model. The primary driver appears to be the presence of annuals. Desert scrub communities illustrate dramatic changes in both species diversity and dominance–diversity relationships in high and low rainfall years, because of the disappearance of annuals in drought years.</p><p><strong>Main conclusions</strong> Species–area curves for immature shrublands in California and the majority of Mediterranean plant communities fit a power function model. Exceptions that fit the exponential model are not because of sampling error or scaling effects, rather structural differences in these communities provide plausible explanations. The exponential species–area model may arise in more than one way. In the highly diverse Australian heathlands it results from a rapid increase in species richness at small scales. In mature California shrublands it results from very depauperate richness at the community scale. In both instances the exponential model is tied to a preponderance of perennials and paucity of annuals. For communities fit by a power model, coefficients <i>z</i> and log <i>c</i> exhibit a number of significant correlations with other diversity parameters, suggesting that they have some predictive value in ecological communities.</p>","language":"English","publisher":"Wiley","doi":"10.1046/j.1365-2699.2003.00950.x","usgsCitation":"Keeley, J.E., and Fotheringham, C.J., 2003, Species area relationships in mediterranean-climate plant communities: Journal of Biogeography, v. 30, no. 11, p. 1629-1657, https://doi.org/10.1046/j.1365-2699.2003.00950.x.","productDescription":"29 p.","startPage":"1629","endPage":"1657","numberOfPages":"29","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":133063,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"30","issue":"11","noUsgsAuthors":false,"publicationDate":"2003-10-23","publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699f0a","contributors":{"authors":[{"text":"Keeley, Jon E. 0000-0002-4564-6521 jon_keeley@usgs.gov","orcid":"https://orcid.org/0000-0002-4564-6521","contributorId":1268,"corporation":false,"usgs":true,"family":"Keeley","given":"Jon","email":"jon_keeley@usgs.gov","middleInitial":"E.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":317461,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fotheringham, C.

The code goby&nbsp;</span><i>Gobiosoma robustum</i><span>&nbsp;Ginsburg and clown goby&nbsp;</span><i>Microgobius gulosus</i><span>&nbsp;(Girard) are common, ecologically similar fishes found throughout the Gulf of Mexico and in the southeastern Atlantic Ocean. In Florida Bay, these fishes exhibit habitat partitioning:&nbsp;</span><i>G. robustum</i><span>&nbsp;is most abundant in seagrass-dominated areas while&nbsp;</span><i>M. gulosus</i><span>&nbsp;is most abundant in sparsely vegetated habitats. In a small-scale field survey, I documented the microhabitat use of these species where their distributions overlap. In a series of laboratory experiments, I presented each species with structured (artificial seagrass) versus nonstructured (bare sand) habitats and measured their frequency of choosing either habitat type. I then examined the use of structured versus nonstructured habitats when the two species were placed together in a mixed group. Finally, I placed a predator (</span><i>Opsanus beta</i><span>) in the experimental aquaria to determine how its presence influenced habitat selection. In the field,&nbsp;</span><i>G. robustum</i><span>&nbsp;was more abundant in seagrass and&nbsp;</span><i>M. gulosus</i><span>&nbsp;was more abundant in bare mud. In the laboratory, both species selected grass over sand in allopatry. However, in sympatry,&nbsp;</span><i>M. gulosus</i><span>&nbsp;occupied sand more often when paired with&nbsp;</span><i>G. robustum</i><span>&nbsp;than when alone.&nbsp;</span><i>G. robustum</i><span>&nbsp;appears to directly influence the habitat choice of&nbsp;</span><i>M. gulosus</i><span>: It seems that&nbsp;</span><i>M. gulosus</i><span>&nbsp;is pushed out of the structured habitat that is the preferred habitat of&nbsp;</span><i>G. robustum</i><span>. Thus, competition appears to modify the habitat selection of these species when they occur in sympatry. Additionally, the presence of the toadfish was a sufficient stimulus to provoke both&nbsp;</span><i>M. gulosus</i><span>&nbsp;and&nbsp;</span><i>G. robustum</i><span>&nbsp;to increase their selection for sand (compared to single-species treatments). Distribution patterns of&nbsp;</span><i>M. gulosus</i><span>&nbsp;and&nbsp;</span><i>G. robustum</i><span>&nbsp;likely result from a synthesis of various biotic and abiotic filters, including physiological tolerances to environmental factors, dispersal ability of larvae, and availability of food. Selection for structural complexity, competition, and presence of predators may further define the resulting pattern of distribution observed in the field.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/S0022-0981(03)00004-2","usgsCitation":"Schofield, P., 2003, Habitat selection of two gobies (<i>Microgobius gulosus, Gobiosoma robustum</i>): influence of structural complexity, competitive interactions and presence of a predator: Journal of Experimental Marine Biology and Ecology, v. 288, no. 1, p. 125-137, https://doi.org/10.1016/S0022-0981(03)00004-2.","productDescription":"13 p.","startPage":"125","endPage":"137","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":132371,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"288","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a7fe4b07f02db6486a2","contributors":{"authors":[{"text":"Schofield, P.

Surgeries involving implantation of transmitters and other instruments into the coelom, which now comprise a very common research tool in the study of free-ranging fishes, are examples of surgeries that use a broad spectrum of surgical and anesthetic techniques, some of which would not be considered acceptable for similar work on mammals. IACUCs should apply the standards they would expect to be used for surgeries on homeotherms to surgeries on fish. Surgeons should be carefully trained and experienced. Surgical instruments and transmitters should be sterile.

Emerging Infectious Diseases 5:735-748). In Colorado, B. dendrobatidis has infected Boreal toads (Bufo boreas) (Muths et. al., in review) and has been identified on museum specimens of northern leopard frogs (Rana pipiens) (Carey et. al. 1999. Develop. Comp. Immunol. 23:459-472). We report the first verified case of chytrid fungus in chorus frogs (Pseudacris triseriata) and wood frogs (Rana sylvatica) in the United States. We collected seven P. triseriata, and two adult and two juvenile R. sylvatica in the Kawuneeche Valley in Rocky Mountain National Park (RMNP) during June 2001. These animals were submitted to the National Wildlife Health Center (NWHC) as part of an amphibian health evaluation in RMNP. Chorus frogs were shipped in one container. Wood frog adults and juveniles were shipped in two separate containers. Histological examinations of all chorus frogs and 3 of 4 wood frogs were positive for chytrid fungus infection. The fourth (adult) wood frog was too decomposed for meaningful histology. Histological findings consisted of multifocally mild to diffusely severe infections of the epidermis of the ventrum and hindlimb digital skin. Chytrid thalli were confined to the thickened epidermis (hyperkeratosis), were spherical to oval, and occasional thalli contained characteristic discharge pores or zoospores (Green and Kagarise Sherman 1999. J. Herpetol 35:92-103; Fellers et al. 2001. Copeia 2001:945-953). We cannot confirm that all specimens carried the fungus at collection, because infection may have spread from one individual to all other individuals in each container during transport. Further sampling of amphibians in Kawuneeche Valley is warranted to determine the rate of infection and mortality in these populations.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Herpetological Review","largerWorkSubtype":{"id":10,"text":"Journal

For this purpose, a series of experiments and simulations was performed using a two-dimensional heterogeneous system (10??1.2 m), which represents an intermediate scale between laboratory and field scales. Tracer tests performed prior to injecting the NAPL provide the baseline response of the heterogeneous porous medium. Two NAPL spill experiments were performed and the entrapped-NAPL saturation distribution measured in detail using a gamma-ray attenuation system. Tracer tests following each of the NAPL spills produced breakthrough curves (BTCs) reflecting the impact of entrapped NAPL on conservative transport. To evaluate significance, the impact of NAPL entrapment on the conservative-tracer breakthrough curves was compared to simulated breakthrough curve variability for different realizations of the heterogeneous distribution. Analysis of the results reveals that the NAPL entrapment has a significant impact on the temporal moments of conservative-tracer breakthrough curves. ?? 2003 Elsevier B.V.

During a recent boating season (late April to September 1999), concentrations of MTBE typically exceeded 20&nbsp;μg/L. MTBE concentrations varied daily from 12 to 24&nbsp;μg/L over a 2-week period that included the Labor Day holiday. Concentrations were highest on weekends when there is more boat traffic, which had an immediate effect on MTBE mass throughout the lake. MTBE concentrations decreased to about 2&nbsp;μg/L shortly after the end of the summer recreational season. The loss of MTBE can be accounted for by volatilization, with a half-life on the order of 10 days. The volatilization rate was modeled with the daily decrease in MTBE then the modeled rate was validated using the data from the seasonal decline.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/S0043-1354(03)00243-4","issn":"00431354","usgsCitation":"Toran, L., Lipka, C., Baehr, A., Reilly, T., and Baker, R., 2003, Seasonal and daily variations in concentrations of methyl-tertiary-butyl ether (MTBE) at Cranberry Lake, New Jersey: Water Research, v. 37, no. 15, p. 3756-3766, https://doi.org/10.1016/S0043-1354(03)00243-4.","productDescription":"11 p.","startPage":"3756","endPage":"3766","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":235766,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209386,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0043-1354(03)00243-4"}],"country":"United States","state":"New Jersey","otherGeospatial":"Cranberry Lake","volume":"37","issue":"15","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8869e4b08c986b316966","contributors":{"authors":[{"text":"Toran, L.","contributorId":78519,"corporation":false,"usgs":true,"family":"Toran","given":"L.","affiliations":[],"preferred":false,"id":404033,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lipka, C.","contributorId":48368,"corporation":false,"usgs":true,"family":"Lipka","given":"C.","email":"","affiliations":[],"preferred":false,"id":404031,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Baehr, A.","contributorId":29619,"corporation":false,"usgs":true,"family":"Baehr","given":"A.","affiliations":[],"preferred":false,"id":404030,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Reilly, T.","contributorId":53138,"corporation":false,"usgs":true,"family":"Reilly","given":"T.","affiliations":[],"preferred":false,"id":404032,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Baker, R.","contributorId":11542,"corporation":false,"usgs":true,"family":"Baker","given":"R.","affiliations":[],"preferred":false,"id":404029,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Because hyperpycnal river discharge commonly occurs during brief periods (hours to occasionally days), mean daily flow statistics often do not reveal the magnitude of these events. Hyperpycnal events are particularly important in rivers draining the Transverse Range and account for 75% of the cumulative sediment load discharged by the Santa Clara River over the past 50 yr. These events are highly pulsed, totaling only ??? 30 days (??? 0.15% of the total 50 yr period). Observations of the fate of sediment discharge, although rare, are consistent with hyperpycnal river dynamics and the high likelihood of turbidity currents during these events. We suggest that much of the sediment load initially bypasses the littoral circulation cells and is directly deposited on the adjacent continental shelf, thus potentially representing a loss of immediate beach sand supply. During particularly exceptional events (>100 yr recurrence intervals), flood underflows may extend past the shelf and escape to offshore basins.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/G19671.1","issn":"00917613","usgsCitation":"Warrick, J., and Milliman, J., 2003, Hyperpycnal sediment discharge from semiarid southern California rivers: Implications for coastal sediment budgets: Geology, v. 31, no. 9, p. 781-784, https://doi.org/10.1130/G19671.1.","startPage":"781","endPage":"784","numberOfPages":"4","costCenters":[],"links":[{"id":209387,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/G19671.1"},{"id":235767,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a37b8e4b0c8380cd610dc","contributors":{"authors":[{"text":"Warrick, J.A.","contributorId":53503,"corporation":false,"usgs":true,"family":"Warrick","given":"J.A.","affiliations":[],"preferred":false,"id":404034,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Milliman, John D.","contributorId":76735,"corporation":false,"usgs":false,"family":"Milliman","given":"John D.","affiliations":[{"id":6706,"text":"Woods Hole Oceanographic Institution,","active":true,"usgs":false}],"preferred":false,"id":404035,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

At many volcanoes, modest volume (up to 500,000 m 3) debris flows are relatively common (multiple times per century) and typically flow at least 5 km along established drainages. Owing to typical debris-flow velocities there is little time for authorities to provide effective warning of the occurrence of a debris flow to populations within 10 km of a source area. Therefore, people living, working, or recreating along channels that drain volcanoes must learn to recognize potentially hazardous conditions, be aware of the extent of debris-flow hazard zones, and be prepared to evacuate to safer ground when hazardous conditions develop rather than await official warnings or intervention. Debris-flow-modeling and hazard-assessment studies must be augmented with public education programs that emphasize recognizing conditions favorable for triggering landslides and debris flows if effective hazard mitigation is to succeed. ?? 2003 Millpress,.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"International Conference on Debris-Flow Hazards Mitigation: Mechanics, Prediction, and Assessment, Proceedings","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"3rd International Conference on Debris-Flow Hazards Mitigation: Mechanics, Prediction, and Assessment","conferenceDate":"September 10-12, 2003","conferenceLocation":"Davos, Switzerland","language":"English","publisher":"Millpress","usgsCitation":"Major, J., Schilling, S., and Pullinger, C., 2003, Volcanic debris flows in developing countries - The extreme need for public education and awareness of debris-flow hazards, <i>in</i> International Conference on Debris-Flow Hazards Mitigation: Mechanics, Prediction, and Assessment, Proceedings, v. 2, Davos, Switzerland, September 10-12, 2003, p. 1185-1196.","productDescription":"12 p.","startPage":"1185","endPage":"1196","numberOfPages":"12","costCenters":[],"links":[{"id":236022,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc2e0e4b08c986b32ae0d","contributors":{"editors":[{"text":"Rickenmann D.Chen C.L.","contributorId":128322,"corporation":true,"usgs":false,"organization":"Rickenmann D.Chen C.L.","id":536547,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Major, J.

One of the important aspects of the study was to assess the regional value of each station through an assessment of the information transfer among gaging records for low, average, and high flow conditions. This analysis was performed for the main hydrologic regions in the State, and the stations were initially evaluated using a new approach based on entropy analysis. To determine the regional value of each station within a region, several information parameters, including total net information, were defined based on entropy. Stations were ranked based on the total net information. For comparison, the regional value of the same stations was assessed using the generalized least square regression (GLS) method, developed by the US Geological Survey. Finally, a hybrid combination of GLS and entropy was created by including a function of the negative net information as a penalty function in the GLS. The weights of the combined model were determined to maximize the average correlation with the results of GLS and entropy. The entropy and GLS methods were evaluated using the high-flow data from southern Illinois stations. The combined method was compared with the entropy and GLS approaches using the high-flow data from eastern Illinois stations. ?? 2003 Elsevier B.V.
