Because it is uniformly fatal, the disease is a major concern in the management of white-tailed deer populations. Management programs to control CWD require improved knowledge of deer interaction, movement, and population connectivity that could influence disease transmission and spread. Genetic methods were employed to evaluate connectivity among populations in the CWD management zone of southern Wisconsin. A 576-base-pair region of the mitochondrial DNA of 359 white-tailed deer from 12 sample populations was analyzed. Fifty-eight variable sites were detected within the sequence, defining 43 haplotypes. While most sample populations displayed similar levels of haplotype diversity, individual haplotypes were clustered on the landscape. Spatial clusters of different haplotypes were apparent in distinct ecoregions surrounding CWD outbreak areas. The spatial distribution of mtDNA haplotypes suggests that clustering of the deer matrilineal groups and population connectivity are associated with broad-scale geographic landscape features. These landscape characteristics may also influence the contact rates between groups and therefore the potential spread of CWD; this may be especially true of local disease spread between female social groups. Our results suggest that optimal CWD management needs to be tailored to fit gender-specific dispersal behaviors and regional differences in deer population connectivity. This information will help wildlife managers design surveillance and monitoring efforts based on population interactions and potential deer movement among CWD-affected and unaffected areas.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/15287394.2011.618980","issn":"15287394","usgsCitation":"Rogers, K., Robinson, S., Samuel, M., and Grear, D., 2011, Diversity and distribution of white-tailed deer mtDNA lineages in chronic wasting disease (CWD) outbreak areas in southern Wisconsin, USA: Journal of Toxicology and Environmental Health, Part A, v. 74, no. 22-24, p. 1521-1535, https://doi.org/10.1080/15287394.2011.618980.","productDescription":"15 p.","startPage":"1521","endPage":"1535","numberOfPages":"15","costCenters":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"links":[{"id":243010,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Wisconsin","otherGeospatial":"Southern Wisconsin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -87.802734375,\n              42.47209690919285\n            ],\n            [\n              -87.86865234374999,\n              43.18114705939968\n            ],\n            [\n              -91.16455078125,\n              43.35713822211053\n            ],\n            [\n              -91.23046875,\n              43.08493742707592\n            ],\n            [\n              -91.03271484375,\n              42.69858589169842\n            ],\n            [\n              -90.703125,\n              42.58544425738491\n            ],\n            [\n              -90.703125,\n              42.48830197960227\n            ],\n            [\n              -87.802734375,\n              42.47209690919285\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"74","issue":"22-24","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0350e4b0c8380cd50412","contributors":{"authors":[{"text":"Rogers, K.G.","contributorId":27693,"corporation":false,"usgs":true,"family":"Rogers","given":"K.G.","email":"","affiliations":[],"preferred":false,"id":450230,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Robinson, S.J.","contributorId":68980,"corporation":false,"usgs":true,"family":"Robinson","given":"S.J.","email":"","affiliations":[],"preferred":false,"id":450231,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Samuel, M.D.","contributorId":13910,"corporation":false,"usgs":true,"family":"Samuel","given":"M.D.","affiliations":[],"preferred":false,"id":450229,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Grear, D.A. 0000-0002-5478-1549","orcid":"https://orcid.org/0000-0002-5478-1549","contributorId":6253,"corporation":false,"usgs":true,"family":"Grear","given":"D.A.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":false,"id":450228,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

However, the threat of invasion is likely to increase because of climate change, greater anthropogenic land use, and continuing novel introductions. Preventive management, therefore, will be crucial but can be difficult to promote when more pressing problems are unresolved and predictions are uncertain. In this essay, we use management case studies from 7 mountain regions to identify common lessons for effective preventive action. The degree of plant invasion in mountains was variable in the 7 regions as was the response to invasion, which ranged from lack of awareness by land managers of the potential impact in Chile and Kashmir to well-organized programs of prevention and containment in the United States (Hawaii and the Pacific Northwest), including prevention at low altitude. In Australia, awareness of the threat grew only after disruptive invasions. In South Africa, the economic benefits of removing alien plants are well recognized and funded in the form of employment programs. In the European Alps, there is little need for active management because no invasive species pose an immediate threat. From these case studies, we identify lessons for management of plant invasions in mountain ecosystems: (i) prevention is especially important in mountains because of their rugged terrain, where invasions can quickly become unmanageable; (ii) networks at local to global levels can assist with awareness raising and better prioritization of management actions; (iii) the economic importance of management should be identified and articulated; (iv) public acceptance of management programs will make them more effective; and (v) climate change needs to be considered. We suggest that comparisons of local case studies, such as those we have presented, have a pivotal place in the proactive solution of global change issues.</span></p>","language":"English","publisher":"BioOne","doi":"10.1659/MRD-JOURNAL-D-11-00082.1","issn":"02764741","usgsCitation":"McDougall, K., Khuroo, A., Loope, L.L., Parks, C., Pauchard, A., Reshi, Z., Rushworth, I., and Kueffer, C., 2011, Plant invasions in mountains: Global lessons for better management: Mountain Research and Development, v. 31, no. 4, p. 380-387, https://doi.org/10.1659/MRD-JOURNAL-D-11-00082.1.","productDescription":"8 p.","startPage":"380","endPage":"387","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-033032","costCenters":[{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"links":[{"id":475478,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1659/mrd-journal-d-11-00082.1","text":"Publisher Index Page"},{"id":242938,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7bf7e4b0c8380cd7970b","contributors":{"authors":[{"text":"McDougall, K.L.","contributorId":32366,"corporation":false,"usgs":true,"family":"McDougall","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":450198,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Khuroo, A.A.","contributorId":60870,"corporation":false,"usgs":true,"family":"Khuroo","given":"A.A.","affiliations":[],"preferred":false,"id":450203,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Loope, Lloyd L.","contributorId":107848,"corporation":false,"usgs":true,"family":"Loope","given":"Lloyd","email":"","middleInitial":"L.","affiliations":[{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"preferred":false,"id":450200,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Parks, C.G.","contributorId":12282,"corporation":false,"usgs":true,"family":"Parks","given":"C.G.","email":"","affiliations":[],"preferred":false,"id":450196,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Pauchard, A.","contributorId":15421,"corporation":false,"usgs":true,"family":"Pauchard","given":"A.","affiliations":[],"preferred":false,"id":450197,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Reshi, Z.A.","contributorId":33937,"corporation":false,"usgs":true,"family":"Reshi","given":"Z.A.","affiliations":[],"preferred":false,"id":450199,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Rushworth, I.","contributorId":58487,"corporation":false,"usgs":true,"family":"Rushworth","given":"I.","email":"","affiliations":[],"preferred":false,"id":450202,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Kueffer, C.","contributorId":55660,"corporation":false,"usgs":true,"family":"Kueffer","given":"C.","affiliations":[],"preferred":false,"id":450201,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

This paper examines the wave and surge climate on Bolivar during the storm and the consequent survival and destruction of buildings. Emphasis is placed on differences between buildings that survived (with varying degrees of damage) and buildings that were completely destroyed. Building elevations are found to be the primary indicator of survival for areas with large waves. Here, buildings that were sufficiently elevated above waves and surge suffered relatively little structural damage, while houses at lower elevations were impacted by large waves and generally completely destroyed. In many areas, the transition from destruction to survival was over a very small elevation range of around 0.5 m. In areas where waves were smaller, survival was possible at much lower elevations. Higher houses that were not inundated still survived, but well-built houses at lower elevations could also survive as the waves were not large enough to cause structural damage. However, the transition height where waves became damaging could not be determined from this study. ?? 2011 American Society of Civil Engineers.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Waterway, Port, Coastal and Ocean Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1061/(ASCE)WW.1943-5460.0000061","issn":"0733950X","usgsCitation":"Kennedy, A., Rogers, S., Sallenger, A., Gravois, U., Zachry, B., Dosa, M., and Zarama, F., 2011, Building destruction from waves and surge on the bolivar peninsula during hurricane ike: Journal of Waterway, Port, Coastal and Ocean Engineering, v. 137, no. 3, p. 132-141, https://doi.org/10.1061/(ASCE)WW.1943-5460.0000061.","startPage":"132","endPage":"141","numberOfPages":"10","costCenters":[],"links":[{"id":214414,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/(ASCE)WW.1943-5460.0000061"},{"id":242138,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"137","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f2a8e4b0c8380cd4b298","contributors":{"authors":[{"text":"Kennedy, A.","contributorId":68975,"corporation":false,"usgs":true,"family":"Kennedy","given":"A.","email":"","affiliations":[],"preferred":false,"id":442938,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rogers, S.","contributorId":6563,"corporation":false,"usgs":true,"family":"Rogers","given":"S.","affiliations":[],"preferred":false,"id":442933,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sallenger, A.","contributorId":49198,"corporation":false,"usgs":true,"family":"Sallenger","given":"A.","affiliations":[],"preferred":false,"id":442935,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gravois, U.","contributorId":63230,"corporation":false,"usgs":true,"family":"Gravois","given":"U.","email":"","affiliations":[],"preferred":false,"id":442937,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Zachry, B.","contributorId":50742,"corporation":false,"usgs":true,"family":"Zachry","given":"B.","email":"","affiliations":[],"preferred":false,"id":442936,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Dosa, M.","contributorId":81320,"corporation":false,"usgs":true,"family":"Dosa","given":"M.","email":"","affiliations":[],"preferred":false,"id":442939,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Zarama, F.","contributorId":26531,"corporation":false,"usgs":true,"family":"Zarama","given":"F.","email":"","affiliations":[],"preferred":false,"id":442934,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Whereas all methods are formulated in terms of the true semivariogram, in practice what can be used are estimated semivariograms and models based on samples. A generalized form of the bootstrap method to properly model spatially correlated data is used to advance knowledge about the reliability of empirical semivariograms and semivariogram models based on a single sample. Among several methods available to generate spatially correlated resamples, we selected a method based on the LU decomposition and used several examples to illustrate the approach. The first one is a synthetic, isotropic, exhaustive sample following a normal distribution, the second example is also a synthetic but following a non-Gaussian random field, and a third empirical sample consists of actual raingauge measurements. Results show wider confidence intervals than those found previously by others with inadequate application of the bootstrap. Also, even for the Gaussian example, distributions for estimated semivariogram values and model parameters are positively skewed. In this sense, bootstrap percentile confidence intervals, which are not centered around the empirical semivariogram and do not require distributional assumptions for its construction, provide an achieved coverage similar to the nominal coverage. The latter cannot be achieved by symmetrical confidence intervals based on the standard error, regardless if the standard error is estimated from a parametric equation or from bootstrap.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s11004-010-9269-6","issn":"18748961","usgsCitation":"Olea, R., and Pardo-Iguzquiza, E., 2011, Generalized bootstrap method for assessment of uncertainty in semivariogram inference: Mathematical Geosciences, v. 43, no. 2, p. 203-228, https://doi.org/10.1007/s11004-010-9269-6.","productDescription":"26 p.","startPage":"203","endPage":"228","ipdsId":"IP-013963","costCenters":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":242905,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215127,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s11004-010-9269-6"}],"volume":"43","issue":"2","noUsgsAuthors":false,"publicationDate":"2010-02-24","publicationStatus":"PW","scienceBaseUri":"505a1515e4b0c8380cd54cad","contributors":{"authors":[{"text":"Olea, Ricardo A. 0000-0003-4308-0808","orcid":"https://orcid.org/0000-0003-4308-0808","contributorId":26436,"corporation":false,"usgs":true,"family":"Olea","given":"Ricardo A.","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":false,"id":450190,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pardo-Iguzquiza, E.","contributorId":34345,"corporation":false,"usgs":true,"family":"Pardo-Iguzquiza","given":"E.","affiliations":[],"preferred":false,"id":450191,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Historic data from Yukon River (Alaska) Chinook salmon&nbsp;</span><i>Oncorhynchus tshawytscha</i><span><span>&nbsp;</span>suggest that length‐adjusted fecundity differs among populations within the drainage and either is temporally variable or has declined. Yukon River Chinook salmon have been harvested in large‐mesh gill‐net fisheries for decades, and a decline in fecundity was considered a potential evolutionary response to size‐selective exploitation. The implications for fishery conservation and management led us to further investigate the fecundity of Yukon River Chinook salmon populations. Matched observations of fecundity, length, and genotype were collected from a sample of adult females captured from the multipopulation spawning migration near the mouth of the Yukon River in 2008. These data were modeled by using a new mixture model, which was developed by extending the conditional maximum likelihood mixture model that is commonly used to estimate the composition of multipopulation mixtures based on genetic data. The new model facilitates maximum likelihood estimation of stock‐specific fecundity parameters without first using individual assignment to a putative population of origin, thus avoiding potential biases caused by assignment error. The hypothesis that fecundity of Chinook salmon has declined was not supported; this result implies that fecundity exhibits high interannual variability. However, length‐adjusted fecundity estimates decreased as migratory distance increased, and fecundity was more strongly dependent on fish size for populations spawning in the middle and upper portions of the drainage. These findings provide insights into potential constraints on reproductive investment imposed by long migrations and warrant consideration in fisheries management and conservation. The new mixture model extends the utility of genetic markers to new applications and can be easily adapted to study any observable trait or condition that may vary among populations.</span></p>","language":"English","publisher":"Wiley","doi":"10.1080/00028487.2011.558776","issn":"00028487","usgsCitation":"Bromaghin, J.F., Evenson, D., McLain, T., and Flannery, B.G., 2011, Using a genetic mixture model to study phenotypic traits: Differential fecundity among Yukon river Chinook Salmon: Transactions of the American Fisheries Society, v. 140, no. 2, p. 235-249, https://doi.org/10.1080/00028487.2011.558776.","productDescription":"15 p.","startPage":"235","endPage":"249","numberOfPages":"15","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":242205,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214477,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/00028487.2011.558776"}],"volume":"140","issue":"2","noUsgsAuthors":false,"publicationDate":"2011-03-16","publicationStatus":"PW","scienceBaseUri":"505bc021e4b08c986b329f47","contributors":{"authors":[{"text":"Bromaghin, Jeffrey F. 0000-0002-7209-9500 jbromaghin@usgs.gov","orcid":"https://orcid.org/0000-0002-7209-9500","contributorId":139899,"corporation":false,"usgs":true,"family":"Bromaghin","given":"Jeffrey","email":"jbromaghin@usgs.gov","middleInitial":"F.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":442956,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Evenson, D.F.","contributorId":104356,"corporation":false,"usgs":true,"family":"Evenson","given":"D.F.","email":"","affiliations":[],"preferred":false,"id":442958,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McLain, T.H.","contributorId":15899,"corporation":false,"usgs":true,"family":"McLain","given":"T.H.","email":"","affiliations":[],"preferred":false,"id":442955,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Flannery, Blair G.","contributorId":95675,"corporation":false,"usgs":false,"family":"Flannery","given":"Blair","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":442957,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

We collected and digitized on-fault and off-fault displacement data for 9 global strikeslip earthquakes ranging from moment magnitude M 6.5 to M 7.6 and supplemented these with displacements from 13 global earthquakes compiled byWesnousky (2008), who considers events up to M 7.9. Displacements on the primary fault fall off at the rupture ends and are often measured in meters, while displacements on secondary (offfault) or distributed faults may measure a few centimeters up to more than a meter and decay with distance from the rupture. Probability of earthquake rupture is less than 15% for cells 200 m??200 m and is less than 2% for 25 m??25 m cells at distances greater than 200mfrom the primary-fault rupture. Therefore, the hazard for off-fault ruptures is much lower than the hazard near the fault. Our data indicate that rupture displacements up to 35cm can be triggered on adjacent faults at distances out to 10kmor more from the primary-fault rupture. An example calculation shows that, for an active fault which has repeated large earthquakes every few hundred years, fault rupture hazard analysis should be an important consideration in the design of structures or lifelines that are located near the principal fault, within about 150 m of well-mapped active faults with a simple trace and within 300 m of faults with poorly defined or complex traces.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120100035","issn":"00371106","usgsCitation":"Petersen, M., Dawson, T.E., Chen, R., Cao, T., Wills, C., Schwartz, D.P., and Frankel, A., 2011, Fault displacement hazard for strike-slip faults: Bulletin of the Seismological Society of America, v. 101, no. 2, p. 805-825, https://doi.org/10.1785/0120100035.","startPage":"805","endPage":"825","numberOfPages":"21","costCenters":[],"links":[{"id":214478,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120100035"},{"id":242206,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"101","issue":"2","noUsgsAuthors":false,"publicationDate":"2011-03-22","publicationStatus":"PW","scienceBaseUri":"505a0f18e4b0c8380cd5376c","contributors":{"authors":[{"text":"Petersen, M.D.","contributorId":51319,"corporation":false,"usgs":false,"family":"Petersen","given":"M.D.","email":"","affiliations":[],"preferred":false,"id":442961,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dawson, T.

This quest has recently been revived by new empirical data, new analysis methods, and increased computing speed, with the promise that ecologically important insights may be obtainable from a limited knowledge of community interactions. We use empirically based and simulated networks of varying size and connectance to assess two limitations to predicting perturbation responses in multispecies communities: (1) the inaccuracy by which species interaction strengths are empirically quantified and (2) the indeterminacy of species responses due to indirect effects associated with network size and structure. We find that even modest levels of species richness and connectance (??25 pairwise interactions) impose high requirements for interaction strength estimates because system indeterminacy rapidly overwhelms predictive insights. Nevertheless, even poorly estimated interaction strengths provide greater average predictive certainty than an approach that uses only the sign of each interaction. Our simulations provide guidance in dealing with the trade-offs involved in maximizing the utility of network approaches for predicting dynamics in multispecies communities. ?? 2011 by the Ecological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/10-1354.1","issn":"00129658","usgsCitation":"Novak, M., Wootton, J., Doak, D., Emmerson, M., Estes, J.A., and Tinker, M.T., 2011, Predicting community responses to perturbations in the face of imperfect knowledge and network complexity: Ecology, v. 92, no. 4, p. 836-846, https://doi.org/10.1890/10-1354.1.","startPage":"836","endPage":"846","numberOfPages":"11","costCenters":[],"links":[{"id":214504,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/10-1354.1"},{"id":242237,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"92","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a81b1e4b0c8380cd7b699","contributors":{"authors":[{"text":"Novak, M.","contributorId":6248,"corporation":false,"usgs":true,"family":"Novak","given":"M.","email":"","affiliations":[],"preferred":false,"id":442966,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wootton, J.T.","contributorId":60460,"corporation":false,"usgs":true,"family":"Wootton","given":"J.T.","email":"","affiliations":[],"preferred":false,"id":442971,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Doak, D.F.","contributorId":39729,"corporation":false,"usgs":true,"family":"Doak","given":"D.F.","email":"","affiliations":[],"preferred":false,"id":442968,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Emmerson, M.","contributorId":18591,"corporation":false,"usgs":true,"family":"Emmerson","given":"M.","email":"","affiliations":[],"preferred":false,"id":442967,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Estes, J.

Synthetic samples of eutectic liquid bulk composition, which produce eutectic colonies containing 0.35-0.50 volume fraction MS11, were tested as functions of colony size and lamellar spacing, temperature (230-250 K), and confining pressure (0.1 and 50 MPa) to strains ???0.2. Up to a differential stress of 6 MPa, the ice I-MS11 aggregates display an order of magnitude higher effective viscosity and higher stress sensitivity than do aggregates of pure polycrystalline ice at the same conditions. The creep data and associated microstructural observations demonstrate, however, that the aggregates are additionally more brittle than pure ice, approaching rate-independent plasticity that includes rupture of the hydrate phase at 6-8 MPa, depending on the scale of the microstructure. Microstructures of deformed samples reveal forms of semibrittle flow in which the hydrate phase fractures while the ice phase deforms plastically. Semibrittle flow in the icy shell of a planetary body would truncate the lithospheric strength envelope and thereby decrease the depth to the brittle-ductile transition by 55% and reduce the failure limit for compressional surface features from 10 to ???6 MPa. A constitutive equation that includes eutectic colony boundary sliding and intracolony flow is used to describe the steady state rheology of the eutectic aggregates.

The broad range of complex factors influencing coastal systems contributes to large uncertainties in predicting long-term sea level rise impacts. Here we explore and demonstrate the capabilities of a Bayesian network (BN) to predict long-term shoreline change associated with sea level rise and make quantitative assessments of prediction uncertainty. A BN is used to define relationships between driving forces, geologic constraints, and coastal response for the U.S. Atlantic coast that include observations of local rates of relative sea level rise, wave height, tide range, geomorphic classification, coastal slope, and shoreline change rate. The BN is used to make probabilistic predictions of shoreline retreat in response to different future sea level rise rates. Results demonstrate that the probability of shoreline retreat increases with higher rates of sea level rise. Where more specific information is included, the probability of shoreline change increases in a number of cases, indicating more confident predictions. A hindcast evaluation of the BN indicates that the network correctly predicts 71% of the cases. Evaluation of the results using Brier skill and log likelihood ratio scores indicates that the network provides shoreline change predictions that are better than the prior probability. Shoreline change outcomes indicating stability (-1 < rate < 1 m/yr) or erosion (rate < -1 m/yr) tend to occur for two sets of input scenarios. Stable shoreline change rates occur mainly for low rates of relative sea level rise and occur in low-vulnerability geomorphic settings. Rates indicating erosion result for cases where the rate of relative sea level rise is high and moderate-to-high vulnerability geomorphic settings occur. In contrast, accretion (rate > 1 m/yr) was not well predicted. We find that BNs can assimilate important factors contributing to coastal change in response to sea level rise and can make quantitative, probabilistic predictions that can be applied to coastal management decisions.

Although naturally occurring, these trace elements can exceed concentrations that are considered harmful to human health. The results show that pumping-induced hydraulic gradient changes and artificial connection of aquifers by well screens can mix chemically distinct groundwater. Chemical reactions between these mixed groundwaters and solid aquifer materials can result in the mobilization of trace elements such as U, As and Ra, with subsequent transport to water-supply wells. For example, in the High Plains aquifer near York, Nebraska, mixing of shallow, oxygenated, lower-pH water from an unconfined aquifer with deeper, confined, anoxic, higher-pH water is facilitated by wells screened across both aquifers. The resulting higher-O2, lower-pH mixed groundwater facilitated the mobilization of U from solid aquifer materials, and dissolved U concentrations were observed to increase significantly in nearby supply wells. Similar instances of trace element mobilization due to human-induced mixing of groundwaters were documented in: (1) the Floridan aquifer system near Tampa, Florida (As and U), (2) Paleozoic sedimentary aquifers in eastern Wisconsin (As), (3) the basin-fill aquifer underlying the California Central Valley near Modesto (U), and (4) Coastal Plain aquifers of New Jersey (Ra). Adverse water-quality impacts attributed to human activities are commonly assumed to be related solely to the release of the various anthropogenic contaminants to the environment. The results show that human activities including various land uses, well drilling, and pumping rates and volumes can adversely impact the quality of water in supply wells, when associated with naturally-occurring trace elements in aquifer materials. This occurs by causing subtle but significant changes in geochemistry and associated trace element mobilization as well as enhancing advective transport processes.","language":"English","publisher":"Elsevier","doi":"10.1016/j.apgeochem.2011.01.033","issn":"08832927","usgsCitation":"Ayotte, J., Szabo, Z., Focazio, M., and Eberts, S.M., 2011, Effects of human-induced alteration of groundwater flow on concentrations of naturally-occurring trace elements at water-supply wells: Applied Geochemistry, v. 26, no. 5, p. 747-762, https://doi.org/10.1016/j.apgeochem.2011.01.033.","productDescription":"16 p.","startPage":"747","endPage":"762","costCenters":[{"id":468,"text":"New Hampshire-Vermont Water Science Center","active":false,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":475382,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.apgeochem.2011.01.033","text":"Publisher Index Page"},{"id":242074,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -126.21093749999999,\n              49.49667452747045\n            ],\n            [\n              -124.98046874999999,\n              46.07323062540835\n            ],\n            [\n              -125.68359374999999,\n              42.032974332441405\n            ],\n            [\n              -125.33203125,\n              39.232253141714885\n            ],\n            [\n              -122.87109375,\n              36.1733569352216\n            ],\n            [\n              -119.53125,\n              33.43144133557529\n            ],\n            [\n              -116.3671875,\n              32.69486597787505\n            ],\n            [\n              -111.4453125,\n              31.50362930577303\n            ],\n            [\n              -106.875,\n              31.653381399664\n            ],\n            [\n              -95.97656249999999,\n              25.005972656239187\n            ],\n            [\n              -95.625,\n              27.68352808378776\n            ],\n            [\n              -92.98828125,\n              29.38217507514529\n            ],\n            [\n              -88.59374999999999,\n              28.613459424004414\n            ],\n            [\n              -88.24218749999999,\n              29.84064389983441\n            ],\n            [\n              -84.90234375,\n              28.613459424004414\n            ],\n            [\n              -80.68359375,\n              24.046463999666567\n            ],\n            [\n              -79.1015625,\n              25.48295117535531\n            ],\n            [\n              -78.92578124999999,\n              30.751277776257812\n            ],\n            [\n              -76.46484375,\n              34.59704151614417\n            ],\n            [\n              -74.70703125,\n              37.020098201368114\n            ],\n            [\n              -73.30078125,\n              38.8225909761771\n            ],\n            [\n              -70.48828125,\n              40.84706035607122\n            ],\n            [\n              -67.5,\n              43.83452678223682\n            ],\n            [\n              -67.5,\n              47.27922900257082\n            ],\n            [\n              -69.78515625,\n              47.27922900257082\n            ],\n            [\n              -75.76171875,\n              45.82879925192134\n            ],\n            [\n              -81.73828125,\n              42.16340342422401\n            ],\n            [\n              -80.85937499999999,\n              45.089035564831036\n            ],\n            [\n              -84.19921875,\n              46.92025531537451\n            ],\n            [\n              -93.8671875,\n              49.38237278700955\n            ],\n            [\n              -126.21093749999999,\n              49.49667452747045\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"26","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a071ae4b0c8380cd51569","contributors":{"authors":[{"text":"Ayotte, J.

In this paper we describe detailed measurements of the three‐dimensional flow structure and sandbar dynamics of two pools along the Colorado River in the Grand Canyon during a controlled flood release from Glen Canyon Dam. Results indicate that the pools are characterized by large lateral recirculation zones (eddies) resulting from flow separation downstream from the channel constrictions, as well as helical flow structures in the main channel and eddy. The lateral recirculation zones are low‐velocity areas conducive to fine sediment deposition, particularly in the vicinity of the separation and reattachment points and are thus the dominant flow structures controlling sandbar dynamics. The helical flow structures also affect morphology but appear secondary in importance to the lateral eddies. During the controlled flood, sandbars in the separation and reattachment zones at both sites tended to build gradually during the rising limb and peak flow. Deposition in shallow water on the sandbars was accompanied by erosion in deeper water along the sandbar slope at the interface with the main channel. Erosion occurred via rapid mass failures as well as by gradual boundary shear stress driven processes. The flow structures and morphologic links at our study sites are similar to those identified in other river environments, in particular sharply curved meanders and channel confluences where the coexistence of lateral recirculation and helical flows has been documented.</span></p>","language":"English","publisher":"AGU","doi":"10.1029/2009JF001442","issn":"01480227","usgsCitation":"Wright, S., and Kaplinski, M., 2011, Flow structures and sandbar dynamics in a canyon river during a controlled flood, Colorado River, Arizona: Journal of Geophysical Research F: Earth Surface, v. 116, no.

Here we quantified sediment transport in the Everglades by progressively increasing flow velocity in a field flume constructed around undisturbed bed sediment and emergent macrophytes. Suspended sediment < 100 μm was dominant in the lower range of laminar flow and was supplied by detachment from epiphyton. Sediment flux increased by a factor of four and coarse flocculent sediment > 100 μm became dominant at higher velocity steps after a threshold shear stress for bed floc entrainment was exceeded. Shedding of vortices that had formed downstream of plant stems also occurred on that velocity step which promoted additional sediment detachment from epiphyton. Modeling determined that the potentially entrainable sediment reservoir, 46 g m<sup>−2</sup>, was similar to the reservoir of epiphyton (66 g m<sup>−2</sup>) but smaller than the reservoir of flocculent bed sediment (330 g m<sup>−2</sup>). All suspended sediment was enriched in phosphorus (by approximately twenty times) compared with bulk sediment on the bed surface and on plant stems, indicating that the most easily entrainable sediment is also the most nutrient rich (and likely the most biologically active).","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geomorphology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.geomorph.2010.03.028","issn":"0169555X","usgsCitation":"Harvey, J., Noe, G., Larsen, L., Nowacki, D., and McPhillips, L., 2011, Field flume reveals aquatic vegetation's role in sediment and particulate phosphorus transport in a shallow aquatic ecosystem: Geomorphology, v. 126, no. 3-4, p. 297-313, https://doi.org/10.1016/j.geomorph.2010.03.028.","productDescription":"17 p.","startPage":"297","endPage":"313","costCenters":[{"id":434,"text":"National Research Program","active":false,"usgs":true}],"links":[{"id":242107,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214384,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.geomorph.2010.03.028"}],"volume":"126","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0fb8e4b0c8380cd539c1","contributors":{"authors":[{"text":"Harvey, J.

The \"Site Screening, Site Selection, and Initial Characterization for Storage of CO<sub>2</sub> in Deep Geological Formations\" BPM is a compilation of best practices and includes flowchart diagrams illustrating the general decision making process for Site Screening, Site Selection, and Initial Characterization. The BPM integrates the knowledge gained from various programmatic efforts, with particular emphasis on the Characterization Phase through pilot-scale <span>CO</span><sub>2</sub> injection testing of the Validation Phase of the Regional Carbon Sequestration Partnership (RCSP) Initiative. Key geologic and surface elements that suitable candidate storage sites should possess are identified, along with example Site Screening, Site Selection, and Initial Characterization protocols for large-scale geologic storage projects located across diverse geologic and regional settings. This manual has been written as a working document, establishing a framework and methodology for proper site selection for <span>CO</span><sub>2</sub>&nbsp;geologic storage. This will be useful for future <span>CO</span><sub>2</sub> emitters, transporters, and storage providers. It will also be of use in informing local, regional, state, and national governmental agencies of best practices in proper sequestration site selection. Furthermore, it will educate the inquisitive general public on options and processes for geologic <span>CO</span><sub>2</sub> storage. In addition to providing best practices, the manual presents a geologic storage resource and capacity classification system. The system provides a \"standard\" to communicate storage and capacity estimates, uncertainty and project development risk, data guidelines and analyses for adequate site characterization, and guidelines for reporting estimates within the classification based on each project's status.&nbsp;</p>","largerWorkTitle":"Energy Procedia","conferenceTitle":"10th International Conference on Greenhouse Gas Control Technologies","conferenceDate":"19 September 2010 through 23 September 2010","conferenceLocation":"Amsterdam","language":"English","doi":"10.1016/j.egypro.2011.02.427","issn":"18766102","usgsCitation":"Rodosta, T., Litynski, J., Plasynski, S., Hickman, S., Frailey, S., and Myer, L., 2011, U.S. Department of Energy's site screening, site selection, and initial characterization for storage of CO<sub>2</sub> in deep geological formations, <i>in</i> Energy Procedia, v. 4, Amsterdam, 19 September 2010 through 23 September 2010, p. 4664-4671, https://doi.org/10.1016/j.egypro.2011.02.427.","productDescription":"8 p.","startPage":"4664","endPage":"4671","costCenters":[],"links":[{"id":475383,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.egypro.2011.02.427","text":"Publisher Index Page"},{"id":242174,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bba3ee4b08c986b32806d","contributors":{"authors":[{"text":"Rodosta, T.D.","contributorId":30057,"corporation":false,"usgs":true,"family":"Rodosta","given":"T.D.","email":"","affiliations":[],"preferred":false,"id":443117,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Litynski, J.T.","contributorId":64043,"corporation":false,"usgs":true,"family":"Litynski","given":"J.T.","email":"","affiliations":[],"preferred":false,"id":443120,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Plasynski, S.I.","contributorId":48398,"corporation":false,"usgs":true,"family":"Plasynski","given":"S.I.","email":"","affiliations":[],"preferred":false,"id":443118,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hickman, S.","contributorId":79995,"corporation":false,"usgs":true,"family":"Hickman","given":"S.","email":"","affiliations":[],"preferred":false,"id":443122,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Frailey, S.","contributorId":66054,"corporation":false,"usgs":true,"family":"Frailey","given":"S.","email":"","affiliations":[],"preferred":false,"id":443121,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Myer, L.","contributorId":53182,"corporation":false,"usgs":true,"family":"Myer","given":"L.","email":"","affiliations":[],"preferred":false,"id":443119,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Adaptive management is an approach to natural resource management that emphasizes learning through management based on the philosophy that knowledge is incomplete and much of what we think we know is actually wrong. Adaptive management has explicit structure, including careful elucidation of goals, identification of alternative management objectives and hypotheses of causation, and procedures for the collection of data followed by evaluation and reiteration. It is evident that adaptive management has matured, but it has also reached a crossroads. Practitioners and scientists have developed adaptive management and structured decision making techniques, and mathematicians have developed methods to reduce the uncertainties encountered in resource management, yet there continues to be misapplication of the method and misunderstanding of its purpose. Ironically, the confusion over the term \"adaptive management\" may stem from the flexibility inherent in the approach, which has resulted in multiple interpretations of \"adaptive management\" that fall along a continuum of complexity and a priori design. Adaptive management is not a panacea for the navigation of 'wicked problems' as it does not produce easy answers, and is only appropriate in a subset of natural resource management problems where both uncertainty and controllability are high. Nonetheless, the conceptual underpinnings of adaptive management are simple; there will always be inherent uncertainty and unpredictability in the dynamics and behavior of complex social-ecological systems, but management decisions must still be made, and whenever possible, we should incorporate learning into management. ?? 2010 .","language":"English","publisher":"Elsevier","doi":"10.1016/j.jenvman.2010.11.019","usgsCitation":"Allen, C.R., Fontaine, J., Pope, K., and Garmestani, A., 2011, Adaptive management for a turbulent future: Journal of Environmental Management, v. 92, no. 5, p. 1339-1345, https://doi.org/10.1016/j.jenvman.2010.11.019.","productDescription":"7 p.","startPage":"1339","endPage":"1345","ipdsId":"IP-025896","costCenters":[],"links":[{"id":242175,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"92","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e6e4e4b0c8380cd476e9","contributors":{"authors":[{"text":"Allen, Craig R. 0000-0001-8655-8272 allencr@usgs.gov","orcid":"https://orcid.org/0000-0001-8655-8272","contributorId":1979,"corporation":false,"usgs":true,"family":"Allen","given":"Craig","email":"allencr@usgs.gov","middleInitial":"R.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true},{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":443126,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fontaine, J.J.","contributorId":37940,"corporation":false,"usgs":true,"family":"Fontaine","given":"J.J.","email":"","affiliations":[],"preferred":false,"id":443124,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Pope, K.L.","contributorId":20454,"corporation":false,"usgs":true,"family":"Pope","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":443123,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Garmestani, A.S.","contributorId":86882,"corporation":false,"usgs":true,"family":"Garmestani","given":"A.S.","email":"","affiliations":[],"preferred":false,"id":443125,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Iron is an important redox substance, and its transfer and transformation in the wetland ecosystem could be an effective indicator for the environment changes. In this paper, we selected the Naoli River catchment in the Sanjiang Plain, Northeast China as the study area to analyze the dynamics of transfer and transformation of soil iron, and the relationship between iron content change and environmental factors. The results show that the total and crystalline iron contents reach the peak in the depth of 60 cm in soil profile, while the amorphous iron content is higher in the topsoil. In the upper reaches, from the low to high landscape positions, the total and crystalline iron contents decrease from 62.98 g/kg to 41.61 g/kg, 22.82 g/kg to 10.53 g/kg respectively, while the amorphous iron content increases from 2.42 g/kg to 8.88 g/kg. Amorphous iron content has positive correlation with organic matter and soil water contents, while negative correlation with pH. Moreover, both the crystalline and amorphous iron contents present no correlation with total iron content, indicating that environmental factors play a more important role in the transfer and transformation of iron other than the content of the total iron. Different redoximorphic features were found along the soil profile due to the transfer and transformation of iron. E and B horizons of wetland soil in the study area have a matrix Chroma 2 or less, and all the soil types can meet the criteria of American hydric soil indicators except albic soil. ??

Such an increase was not seen for the 2004 M=9.1 Sumatra or 2010 M=8.8 Chile earthquakes, but they lacked the seismic networks necessary to detect such small events. Here we explore the possibility that the rate changes are the product of static Coulomb stress transfer to small faults. We use the nodal planes of M ≥ 3.5 earthquakes as proxies for such small active faults, and find that of fifteen regions averaging ~80 by 80 km in size, 11 show a positive association between calculated stress changes and the observed seismicity rate change, 3 show a negative correlation, and for one the changes are too small to assess. This work demonstrates that seismicity can turn on in the nominal stress shadow of a mainshock as long as small geometrically diverse active faults exist there, which is likely quite common.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geophysical Research Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","publisherLocation":"Washington, D.C.","doi":"10.1029/2011GL047834","issn":"00948276","usgsCitation":"Toda, S., Stein, R., and Lin, J., 2011, Widespread seismicity excitation throughout central Japan following the 2011 M=9.0 Tohoku earthquake and its interpretation by Coulomb stress transfer: Geophysical Research Letters, v. 38, no. 15, 5 p.; L00G03, https://doi.org/10.1029/2011GL047834.","productDescription":"5 p.; L00G03","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":475060,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2011gl047834","text":"Publisher Index Page"},{"id":215305,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2011GL047834"},{"id":243100,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Japan","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 122.9,24.0 ], [ 122.9,45.5 ], [ 154.0,45.5 ], [ 154.0,24.0 ], [ 122.9,24.0 ] ] ] } } ] }","volume":"38","issue":"15","noUsgsAuthors":false,"publicationDate":"2011-08-06","publicationStatus":"PW","scienceBaseUri":"505bd0b9e4b08c986b32f013","contributors":{"authors":[{"text":"Toda, S.","contributorId":102228,"corporation":false,"usgs":true,"family":"Toda","given":"S.","email":"","affiliations":[],"preferred":false,"id":449872,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stein, R.S.","contributorId":8875,"corporation":false,"usgs":true,"family":"Stein","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":449870,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lin, J.","contributorId":33065,"corporation":false,"usgs":true,"family":"Lin","given":"J.","email":"","affiliations":[],"preferred":false,"id":449871,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The endmember values of this range were assumed representative of dry and wet climate states. With respect to precipitation and heat, the Pajarito Plateau area has excellent agricultural potential; the agricultural potentials of the Zuni and Mesa Verde regions are good; and the agricultural potential of the Chaco Halo is poor. Calculations of N mineralization and field life indicate that Morfield Valley in Mesa Verde should be able to provide 10 bu/ac of maize for decades (without the addition of N) when organic N-mineralization rates exceed 2%. Productivity and field-life potential decrease in the following order: Zuni, Mesa Verde, Bandelier, Chaco Halo.

Sound levels were calculated from recordings made throughout behavioral observation periods. An information theoretic approach was used to investigate the relationship between behavior patterns and sound level. Results indicated that elevated sound levels affect manatee activity and are a function of behavioral state. The proportion of time manatees spent feeding and milling changed in response to sound level. When ambient sound levels were highest, more time was spent in the directed, goal-oriented behavior of feeding, whereas less time was spent engaged in undirected behavior such as milling.
