Perceptions of a species’ permanence in an environment or lack thereof frequently drives how limited time, financial, and personnel resources are allocated to such efforts. Language we use to describe a non-native species’ status largely defines these perceptions and sets boundaries, real or perceived, to potential management actions. Here we discuss the use of a particular term – “established” – when confronting management decisions for invasive species. Our objective is to contribute to bridging the gap between the realms of conceptual development and management with respect to use of the term “established”. We find that although there are benefits of polysemy and synonymy to conceptual development they present an additional challenge to managers who must weigh the costs, benefits, and potential for success of particular management actions. We also examine how existing conceptual frameworks might be augmented to bridge the theoretical-practical gap, such as more precisely defining potential management actions and explicitly including assessment of risk.</p>","language":"English","publisher":"REABIC","doi":"10.3391/mbi.2018.9.3.01","usgsCitation":"Kocovsky, P., Sturtevant, R., and Schardt, J., 2018, What it is to be established: policy and management implications for non-native and invasive species: Management of Biological Invasions, v. 9, no. 3, p. 177-185, https://doi.org/10.3391/mbi.2018.9.3.01.","productDescription":"9 p.","startPage":"177","endPage":"185","ipdsId":"IP-090443","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":468436,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3391/mbi.2018.9.3.01","text":"Publisher Index Page"},{"id":357671,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"9","issue":"3","publishingServiceCenter":{"id":15,"text":"Madison PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5bc02fa2e4b0fc368eb5393b","contributors":{"authors":[{"text":"Kocovsky, Patrick 0000-0003-4325-4265 pkocovsky@usgs.gov","orcid":"https://orcid.org/0000-0003-4325-4265","contributorId":150837,"corporation":false,"usgs":true,"family":"Kocovsky","given":"Patrick","email":"pkocovsky@usgs.gov","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":746079,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sturtevant, Rochelle","contributorId":208134,"corporation":false,"usgs":false,"family":"Sturtevant","given":"Rochelle","affiliations":[{"id":37753,"text":"Michigan Sea Grant","active":true,"usgs":false}],"preferred":false,"id":746080,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schardt, James","contributorId":208135,"corporation":false,"usgs":false,"family":"Schardt","given":"James","email":"","affiliations":[{"id":13529,"text":"US Environmental Protection Agency","active":true,"usgs":false}],"preferred":false,"id":746081,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The approach allows dispersion computations for a large suite of discretizations, model dimensions (1-, 2-, or 3-dimensional), spatial and temporal discretization, and turbulence closures. As the model is based on a discrete non-interacting particle approach, parallelization is straightforward, such that simulations with large numbers of particles are tractable. Results from the approach are compared to dispersion measurements made with conventional Rhodamine WT dye experiment in which typical at-a-point sensors are employed to determine concentration. The model performs well, but spatial resolution for experiments over large and or complex river flows was inadequate for model testing. To address this issue, we explored the idea of measuring spatial concentrations in river flows using hyperspectral remote sensing. Experiments both for idealized channels and real rivers show that this technique is viable and can provide high levels of spatial detail in concentration measurements with quantitatively accurate concentrations.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"E3S Web of Conferences","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"River Flow 2018 -

We found that the choice of model had an impact on the estimability of unknown model parameters and affected the bias and variance of corrected counts. Finite mixture models provided better fit than conventional removal models and better adjusted for count duration. However, reliably estimating parameters and minimizing variance using mixture models required at least 200–1,000 detections. Mixture models with time-varying proportions of infrequent singers were best supported across species, indicating that accounting for date- and time-related heterogeneity is important when combining data across studies over large spatial scales, multiple sampling time frames, or variable survey protocols. Our flexible and continuous time-removal modeling framework can be used to account for such heterogeneity through the incorporation of easily obtainable covariates, such as methods, date, time, and location. Accounting for availability bias in bird surveys allows for better integration of disparate studies at large spatial scales and better adjustment of local, regional, and continental population size estimates.</span></p>","language":"English","publisher":"American Ornithological Society","doi":"10.1650/CONDOR-18-32.1","usgsCitation":"Solymos, P., Matsuoka, S.M., Cumming, S.G., Stralberg, D., Fontaine, P.C., Schmiegelow, F.K., Song, S.J., and Bayne, E.M., 2018, Evaluating time-removal models for estimating availability of boreal birds during point count surveys: Sample size requirements and model complexity: Condor, v. 120, no. 4, p. 765-786, https://doi.org/10.1650/CONDOR-18-32.1.","productDescription":"22 p.","startPage":"765","endPage":"786","ipdsId":"IP-095119","costCenters":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"links":[{"id":468438,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1650/condor-18-32.1","text":"Publisher Index Page"},{"id":357080,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -178.59375,\n              43.197167282501276\n            ],\n            [\n              -53.0859375,\n              43.197167282501276\n            ],\n            [\n              -53.0859375,\n              70.8446726342528\n            ],\n            [\n              -178.59375,\n              70.8446726342528\n            ],\n            [\n              -178.59375,\n              43.197167282501276\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"120","issue":"4","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationDate":"2018-08-29","publicationStatus":"PW","scienceBaseUri":"5b98a267e4b0702d0e842e74","contributors":{"authors":[{"text":"Solymos, Peter","contributorId":203718,"corporation":false,"usgs":false,"family":"Solymos","given":"Peter","email":"","affiliations":[{"id":36696,"text":"University of Alberta","active":true,"usgs":false}],"preferred":false,"id":744118,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Matsuoka, Steven M. 0000-0001-6415-1885 smatsuoka@usgs.gov","orcid":"https://orcid.org/0000-0001-6415-1885","contributorId":184173,"corporation":false,"usgs":true,"family":"Matsuoka","given":"Steven","email":"smatsuoka@usgs.gov","middleInitial":"M.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":744117,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cumming, Steven G.","contributorId":207538,"corporation":false,"usgs":false,"family":"Cumming","given":"Steven","email":"","middleInitial":"G.","affiliations":[{"id":37556,"text":"University of Laval","active":true,"usgs":false}],"preferred":false,"id":744119,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stralberg, Diana","contributorId":187413,"corporation":false,"usgs":false,"family":"Stralberg","given":"Diana","email":"","affiliations":[],"preferred":false,"id":744120,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fontaine, Patricia C.","contributorId":140676,"corporation":false,"usgs":false,"family":"Fontaine","given":"Patricia","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":744121,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Schmiegelow, Fiona K.

Morphologic characteristics of channels—e.g., width, depth, slope, and the relationships among them—can constrain interpretations of channel-forming processes. This work uses morphometric scaling relationships extracted from high-resolution seafloor bathymetry to infer connections between morphology and process in submarine channels. Analysis of 36 modern channels in five geographic regions shows that channel widths vary regionally (from &lt;100&nbsp;m to &gt;10&nbsp;km wide) but occupy the same range of aspect ratios (~10:1–100:1). This suggests an autogenic control on aspect ratio, perhaps resulting from feedback processes in levee growth and/or bank erosion, and allogenic (e.g., sediment supply, grain size) controls on channel width. Submarine channel aspect ratios tend to decrease with increasing dimensions, while the opposite relationship has been observed for fluvial channels, likely due to opposing relationships between flow discharge and channel distance. Additionally, observation of an apparent lag between channel thalweg and levee responses to gradient changes suggests that thalweg and levee deposition and erosion may be partially decoupled due to the vertical structure of turbidity currents, with thalweg evolution driven by the basal, higher-shear-stress portion of the flow and levee evolution by the dilute upper portion. The data presented here provide a basis for predicting channel metrics in exploration scenarios, in which data coverage may be sparse. This documentation of a diverse suite of channels also captures the range of scales and variability exhibited globally by sub­marine channel systems, providing context for local studies.</span></p>","language":"English","publisher":"Geologic Society of America","doi":"10.1130/GES01674.1","usgsCitation":"Shumaker, L.E., Jobe, Z.R., Johnstone, S., Pettinga, L.A., Cai, D., and Moody, J.D., 2018, Controls on submarine channel-modifying processes identified through morphometric scaling relationships: Geosphere, v. 14, no. 5, p. 2171-2187, https://doi.org/10.1130/GES01674.1.","productDescription":"17 p.","startPage":"2171","endPage":"2187","ipdsId":"IP-094567","costCenters":[{"id":35995,"text":"Geology, Geophysics, and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":468439,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1130/ges01674.1","text":"Publisher Index Page"},{"id":357077,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"14","issue":"5","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2018-08-10","publicationStatus":"PW","scienceBaseUri":"5b98a268e4b0702d0e842e76","contributors":{"authors":[{"text":"Shumaker, Lauren E.","contributorId":207546,"corporation":false,"usgs":false,"family":"Shumaker","given":"Lauren","email":"","middleInitial":"E.","affiliations":[{"id":37560,"text":"Department of Geology and Geological Engineering, Colorado School of Mines, Golden, Colorado 80401, USA","active":true,"usgs":false}],"preferred":false,"id":744136,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jobe, Zane R.","contributorId":207547,"corporation":false,"usgs":false,"family":"Jobe","given":"Zane","email":"","middleInitial":"R.","affiliations":[{"id":37560,"text":"Department of Geology and Geological Engineering, Colorado School of Mines, Golden, Colorado 80401, USA","active":true,"usgs":false}],"preferred":false,"id":744137,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Johnstone, Samuel 0000-0002-3945-2499","orcid":"https://orcid.org/0000-0002-3945-2499","contributorId":207545,"corporation":false,"usgs":true,"family":"Johnstone","given":"Samuel","email":"","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true},{"id":35995,"text":"Geology, Geophysics, and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":744135,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pettinga, Luke A.","contributorId":207548,"corporation":false,"usgs":false,"family":"Pettinga","given":"Luke","email":"","middleInitial":"A.","affiliations":[{"id":37560,"text":"Department of Geology and Geological Engineering, Colorado School of Mines, Golden, Colorado 80401, USA","active":true,"usgs":false}],"preferred":false,"id":744138,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Cai, Dingxin","contributorId":207549,"corporation":false,"usgs":false,"family":"Cai","given":"Dingxin","email":"","affiliations":[{"id":37560,"text":"Department of Geology and Geological Engineering, Colorado School of Mines, Golden, Colorado 80401, USA","active":true,"usgs":false}],"preferred":false,"id":744139,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Moody, Jeremiah D.","contributorId":207550,"corporation":false,"usgs":false,"family":"Moody","given":"Jeremiah","email":"","middleInitial":"D.","affiliations":[{"id":37561,"text":"Chevron Energy Technology Company, Houston, TX 77002, USA","active":true,"usgs":false}],"preferred":false,"id":744140,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

We studied the sensitivity of Black Ducks to perturbations in food supply that often result from disturbances by storms, predators, and people. In the paper, we characterize the responses of captive Black Ducks to shifts in food quality and availability during winter and apply those measures to a comparison of wild birds. Captive ducks that were fed intermittently (3 consecutive days/week) compensated for fasted days to achieve similar body mass and body fat to control birds that were fed every day on both animal- and plant-based diets. However, birds that were fed intermittently expended 15% more energy each day than controls when both groups were fed (536 vs. 464&nbsp;kJ/kg</span><sup>0.75</sup><span>), which indicates that variable food supply increases the costs of maintenance and thus reduces the number of birds that can be supported on the same resource of food without interruptions to foraging. Egg production was not affected by diet quality provided in spring or by the frequency of feeding during the preceding winter months. Black Ducks lost body fat through winter in captivity and in the wild. Fat stores of birds in New Jersey were greater than those of birds in Maine (13.3 vs. 8.3% of body mass) in January, which reflected the high energy demands of cold temperatures in Maine. Values for ∂</span><sup>15</sup><span>N were greater in Maine than in New Jersey for both red blood cells and plasma, which indicated a consistent diet of marine invertebrates in Maine.

Plasma ∂</span><sup>13</sup><span>C was enriched over red blood cells in wild birds especially those with low fat stores, which suggested birds with low energy stores were shifting diets. Black Ducks can compensate for disturbances in feeding by increasing intakes if they have access to high quality wetlands where they are able to find abundant food. High energy demands at cold temperatures may constrain fat stores and thus the tolerance of feeding disturbances especially at the northern limits of the winter range. We hypothesize that decreasing variation in diet may indicate an increase in vulnerability to disturbance in winter when body fat is low. Recent efforts to assess and improve habitat quality of Black Ducks could be enhanced by monitoring the body composition and diet of birds to assess their vulnerability to disturbances in food supply and energy demands.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s00360-018-1163-4","usgsCitation":"Barboza, P.S., and Jorde, D.G., 2018, Monitoring responses to variation in food supply for a migratory waterfowl: American Black Duck (Anas rubripes) in winter: Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, v. 188, no. 5, p. 831-842, https://doi.org/10.1007/s00360-018-1163-4.","productDescription":"12 p.","startPage":"831","endPage":"842","ipdsId":"IP-091511","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":357069,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"188","issue":"5","publishingServiceCenter":{"id":10,"text":"Baltimore PSC"},"noUsgsAuthors":false,"publicationDate":"2018-05-26","publicationStatus":"PW","scienceBaseUri":"5b98a268e4b0702d0e842e7a","contributors":{"authors":[{"text":"Barboza, Perry S.","contributorId":36454,"corporation":false,"usgs":false,"family":"Barboza","given":"Perry","email":"","middleInitial":"S.","affiliations":[{"id":13117,"text":"Institute of Arctic Biology, University of Alaska Fairbanks","active":true,"usgs":false}],"preferred":false,"id":744195,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jorde, Dennis G. 0000-0002-2608-3188 djorde@usgs.gov","orcid":"https://orcid.org/0000-0002-2608-3188","contributorId":207566,"corporation":false,"usgs":false,"family":"Jorde","given":"Dennis","email":"djorde@usgs.gov","middleInitial":"G.","affiliations":[{"id":37565,"text":"Retired, USGS Patuxent Wildlife Research Center","active":true,"usgs":false}],"preferred":false,"id":744194,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

In North America's temperate grassland biome, Eastern redcedar (</span><i>Juniperus virginiana</i><span>&nbsp;L.) is a native species used in tree plantings that aggressively invades in the absence of controlling processes. Cedar is a well-studied woody encroacher, but little is known about the degree to which cedar windbreaks, which are advocated for in agroforestry programs, are contributing to woody encroachment, what factors are associated with cedar spread from windbreaks, nor where encroachment from windbreaks is occurring in contemporary social–ecological landscapes. We used remotely sensed imagery to identify the presence and pattern of woody encroachment from windbreaks in the Nebraska Sandhills. We used multimodel inference to compare three classes of models representing three hypotheses about factors that could influence cedar spread: (a) windbreak models based on windbreak structure and design elements; (b) abiotic models focused on local environmental conditions; and (c) landscape models characterizing coupled human-natural features within the broader matrix. Woody encroachment was evident for 23% of sampled windbreaks in the Nebraska Sandhills. Of our candidate models, our inclusive landscape model carried 92% of the model weight. This model indicated that encroachment from windbreaks was more likely near roadways and less likely near farmsteads, other cedar plantings, and waterbodies, highlighting strong social ties to the distribution of woody encroachment from tree plantings across contemporary landscapes. Our model findings indicate where additional investments into cedar control can be prioritized to prevent cedar spread from windbreaks. This approach can serve as a model in other temperate regions to identify where woody encroachment resulting from temperate agroforestry programs is emerging.</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/ece3.4340","usgsCitation":"Donvan, V., Burnett, J., Bielski, C., Birge, H., Bevans, R., Twidwell, D., and Allen, C.R., 2018, Social–ecological landscape patterns predict woody encroachment from native tree plantings in a temperate grassland: Ecology and Evolution, v. 8, no. 19, p. 9624-9632, https://doi.org/10.1002/ece3.4340.","productDescription":"9 p.","startPage":"9624","endPage":"9632","ipdsId":"IP-099576","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":482050,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/ece3.4340","text":"Publisher Index Page"},{"id":481931,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Nebraska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -102.80956986796139,\n              42.910635718325125\n            ],\n            [\n              -102.80956986796139,\n              41.083881420357784\n            ],\n            [\n              -97.90830588361806,\n              41.083881420357784\n            ],\n            [\n              -97.90830588361806,\n              42.910635718325125\n            ],\n            [\n              -102.80956986796139,\n              42.910635718325125\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"8","issue":"19","noUsgsAuthors":false,"publicationDate":"2018-09-05","publicationStatus":"PW","contributors":{"authors":[{"text":"Donvan, V.M.","contributorId":350764,"corporation":false,"usgs":false,"family":"Donvan","given":"V.M.","affiliations":[{"id":36892,"text":"University of Nebraska","active":true,"usgs":false}],"preferred":false,"id":926948,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Burnett, J.L.","contributorId":189790,"corporation":false,"usgs":false,"family":"Burnett","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":926949,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bielski, C.H.","contributorId":273150,"corporation":false,"usgs":false,"family":"Bielski","given":"C.H.","affiliations":[{"id":36892,"text":"University of Nebraska","active":true,"usgs":false}],"preferred":false,"id":926950,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Birge, H.E.","contributorId":350765,"corporation":false,"usgs":false,"family":"Birge","given":"H.E.","affiliations":[{"id":36892,"text":"University of Nebraska","active":true,"usgs":false}],"preferred":false,"id":926951,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bevans, R.","contributorId":350766,"corporation":false,"usgs":false,"family":"Bevans","given":"R.","affiliations":[{"id":36892,"text":"University of Nebraska","active":true,"usgs":false}],"preferred":false,"id":926952,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Twidwell, D.","contributorId":244285,"corporation":false,"usgs":false,"family":"Twidwell","given":"D.","affiliations":[{"id":36892,"text":"University of Nebraska","active":true,"usgs":false}],"preferred":false,"id":926953,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"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":926954,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Sea otters on the west side of LCI are considered part of the southwest Alaska stock; sea otters occupying eastern LCI are considered part of the southcentral Alaska stock.  Information concerning the distributions and abundance of sea otters in LCI is needed to track the status and trends of these populations and address management concerns associated with oil and gas exploration and coastal development in the region.  In May 2017, we conducted a series of replicate aerial surveys of sea otters across LCI following the methods of Bodkin and Udevitz (1999).  Our abundance estimate for western LCI (southwest Alaska stock) was 10,737 (SE = 2,323) sea otters.  Sea otters were not uniformly distributed across western LCI.  The highest sea otter densities (up to 8 sea otter/km2) occurred within Kamishak Bay to the west and north of Augustine Island.  Sea otter densities were relatively low north of Kamishak Bay.  The total abundance estimate for eastern LCI (part of the southcentral Alaska stock) was 9,152 (SE = 1,020) sea otters.  The highest densities of sea otters in eastern LCI were found along the north shore of Kachemak Bay and in Port Graham.  We also found large numbers of sea otters along the eastern shore of LCI between Anchor Point and Clam Gulch.  We recommend conducting a sea otter distribution survey in September, prior to the appearance of sea ice, and again during winter to examine potential seasonal shifts in sea otter distributions in LCI.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"USFWS Technical Report","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"U.S. Fish and Wildllife Service","usgsCitation":"Gerlach-Miller, J., Esslinger, G.G., and Weitzman, B., 2018, Aerial surveys of sea otters (Enhydra lutris) in Lower Cook Inlet, Alaska, May, 2017, ii, 22 p.","productDescription":"ii, 22 p.","ipdsId":"IP-100590","costCenters":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"links":[{"id":372052,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":372021,"type":{"id":15,"text":"Index Page"},"url":"https://www.fws.gov/r7/fisheries/mmm/seaotters/reports.htm"}],"country":"United States","state":"Alaska","otherGeospatial":"Lower Cook Inlet","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -153.69873046875,\n              58.859223547066584\n            ],\n            [\n              -151.083984375,\n              59.712097173322924\n            ],\n            [\n              -150.82031249999997,\n              60.68393876805448\n            ],\n            [\n              -149.87548828125,\n              60.74842446462361\n            ],\n            [\n              -148.53515625,\n              60.855613316239335\n            ],\n            [\n              -149.61181640625,\n              61.227957176677876\n            ],\n            [\n              -148.99658203125,\n              61.51221638411366\n            ],\n            [\n              -150.09521484375,\n              61.48075950007598\n            ],\n            [\n              -151.06201171875,\n              61.41775026352097\n            ],\n            [\n              -152.4462890625,\n              60.973107109199404\n            ],\n            [\n              -154.16015625,\n              59.92199002450385\n            ],\n            [\n              -154.44580078125,\n              59.4115481664237\n            ],\n            [\n              -154.48974609375,\n              58.91599192355906\n            ],\n            [\n              -153.69873046875,\n              58.859223547066584\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Gerlach-Miller, Joel","contributorId":222186,"corporation":false,"usgs":false,"family":"Gerlach-Miller","given":"Joel","email":"","affiliations":[{"id":40505,"text":"USFWS - Marine Mammals Management","active":true,"usgs":false}],"preferred":false,"id":781472,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Esslinger, George G. 0000-0002-3459-0083 gesslinger@usgs.gov","orcid":"https://orcid.org/0000-0002-3459-0083","contributorId":131009,"corporation":false,"usgs":true,"family":"Esslinger","given":"George","email":"gesslinger@usgs.gov","middleInitial":"G.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":781471,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Weitzman, Ben 0000-0001-7559-3654","orcid":"https://orcid.org/0000-0001-7559-3654","contributorId":214292,"corporation":false,"usgs":true,"family":"Weitzman","given":"Ben","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":781473,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Digestion of large prey is metabolically and aerobically costly, and large prey boluses can impair snake locomotion, increasing vulnerability to predation. Cessation of foraging and use of refugia with microclimates facilitating digestion are expected to be strategies employed by free‐ranging snakes to cope with the demands of digestion while minimizing risk of predation. However, empirical observations of such submergent behavior from field experiments are limited. The brown treesnake (Serpentes: Colubridae:<span>&nbsp;</span><i>Boiga irregularis</i>) is a nocturnal, arboreal, colubrid snake that was accidentally introduced to the island of Guam, with ecologically and economically costly consequences. Because tools for brown treesnake damage prevention generally rely on snakes being visible or responding to lures or baits while foraging, cessation of foraging activities after feeding would complicate management. We sought to characterize differences in brown treesnake activity, movement, habitat use, and detectability following feeding of large meals (rodents 33% of the snake's unfed body mass) via radio telemetry, trapping, and visual surveys. Compared to unfed snakes, snakes in the feeding treatment group showed drastic decreases in hourly and nightly activity rates, differences in refuge height and microhabitat type, and a marked decrease in detectability by trapping and visual surveys. Depression of activity lasted approximately 5–7&nbsp;days, a period that corresponds to previous studies of brown treesnake digestion and cycles of detectability. Our results indicate that management strategies for invasive brown treesnakes need to account for cycles of unavailability and underscore the importance of preventing spread of brown treesnakes to new environments where large prey are abundant and periods of cryptic behavior are likely to be frequent. Characterization of postfeeding behavior changes provides a richer understanding of snake ecology and foraging models for species that consume large prey.</p></div></div>","language":"English","publisher":"Wiley","doi":"10.1002/ece3.4480","usgsCitation":"Siers, S.R., Yackel Adams, A.A., and Reed, R., 2018, Behavioral differences following ingestion of large meals and consequences for management of a harmful invasive snake: A field experiment: Ecology and Evolution, v. 8, no. 20, p. 10075-10093, https://doi.org/10.1002/ece3.4480.","productDescription":"19 p.","startPage":"10075","endPage":"10093","ipdsId":"IP-099427","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":468442,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/ece3.4480","text":"Publisher Index Page"},{"id":437767,"rank":0,"type":{"id":30,"text":"Data Release"},"url":"https://doi.org/10.5066/P9AD7KKO","text":"USGS data release","linkHelpText":"Brown Treesnake morphological and behavioral differences following ingestion of large meals, 2015"},{"id":385596,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"8","issue":"20","noUsgsAuthors":false,"publicationDate":"2018-09-05","publicationStatus":"PW","contributors":{"authors":[{"text":"Siers, Shane R.","contributorId":152305,"corporation":false,"usgs":false,"family":"Siers","given":"Shane","email":"","middleInitial":"R.","affiliations":[{"id":6621,"text":"Colorado State University","active":true,"usgs":false}],"preferred":false,"id":815528,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yackel Adams, Amy A. 0000-0002-7044-8447 yackela@usgs.gov","orcid":"https://orcid.org/0000-0002-7044-8447","contributorId":3116,"corporation":false,"usgs":true,"family":"Yackel Adams","given":"Amy","email":"yackela@usgs.gov","middleInitial":"A.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":815529,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Reed, Robert 0000-0001-8349-6168 reedr@usgs.gov","orcid":"https://orcid.org/0000-0001-8349-6168","contributorId":152301,"corporation":false,"usgs":true,"family":"Reed","given":"Robert","email":"reedr@usgs.gov","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":815530,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The damages from Hurricane Sandy exceeded $50 billion in total, making it the second most costly Atlantic hurricane at that time, second only to Hurricane Katrina in 2005. Hurricane Sandy also resulted in 147 deaths, and about 650,000 homes and many businesses being damaged along the eastern coast of the United States. The severity of Hurricane Sandy’s effects resulted in presidential disaster declarations being declared in 10 States from Virginia to Massachusetts and the District of Columbia in the months following Hurricane Sandy; the list of States affected included Connecticut, Rhode Island, and Massachusetts.</p><p>In response to the approach of Hurricane Sandy, the USGS deployed 60 temporary storm tide sensors and 2 temporary real-time rapid deployment gages to collect tide elevation data during the storm along the coastal areas of Connecticut, Rhode Island, and Massachusetts. This activity was done from Virginia to Maine before the storm. Following Hurricane Sandy, in October and November 2012, 371 storm tide high-water marks were identified and flagged in the coastal areas of Connecticut, Rhode Island, and Massachusetts. High-water marks near USGS temporary storm tide sensors, real-time rapid deployment gages, and streamgages affected by the tides as well as high-water marks on Block Island, R.I., and Martha’s Vineyard and Nantucket, Mass., were surveyed at the same time the high-water marks were identified and flagged in October and November 2012. The remaining high-water marks flagged during October and November 2012 were surveyed from December 2013 through June 2014 and in December 2016. Elevations of all high-water marks were referenced to the North American Vertical Datum of 1988 and horizontal coordinates to the North American Datum of 1983 using the Global Navigation Satellite System, survey-grade Digital Global Positioning System receivers, and total station surveying equipment.</p><p>Of the 371 storm tide high-water marks flagged following Hurricane Sandy, only 364 high-water marks were surveyed; the remaining 7 could not be found or had been destroyed when locations were revisited to conduct surveys. The 157 high-water marks surveyed in Connecticut had elevations that ranged from 2.5 to 12.2 feet (ft) with an average elevation of 8.1 ft and a median elevation of 8.3 ft. The 76 high-water marks in Rhode Island had elevations that ranged from 3.6 to 16.2 ft and averaged 7.1 ft with a median of 6.6 ft. The 131 high-water marks in Massachusetts had elevations that ranged from 2.8 to 22.7 ft and averaged 7.3 ft with a median of 6.6 ft. Individual information on the location, type, accuracy, and elevation of the 371 high-water marks can be found in an accompanying USGS data release and at the USGS Flood Event Viewer website for Hurricane Sandy (<a href=\"https://stn.wim.usgs.gov/fev/#Sandy\" data-mce-href=\"https://stn.wim.usgs.gov/fev/#Sandy\">https://stn.wim.usgs.gov/fev/#Sandy</a>).</p><p>The high-water marks along the coast line of Connecticut and eastern Massachusetts, including Nantucket, generally had higher storm tide elevations than the coast line of Rhode Island including Block Island and southern Massachusetts, including Martha’s Vineyard. The high-water mark elevations compare well with recorded peak-storm tide data at USGS temporary storm tide sensors and real-time rapid deployment gages deployed for Hurricane Sandy in Connecticut, Rhode Island, and Massachusetts.</p><p>High-water mark data collected following Hurricane Sandy will be used by Federal, State, and local government agencies, nongovernmental organizations, universities, and the public for better understanding the areal extent and impact of the storm tides. Additionally, these data can be used for such activities as land-use planning, flood risk studies, flood resiliency studies, and coastal modeling. These data from this historic storm can be compared with other regional hurricanes and tropical storms for planning into the future.</p>","language":"English","publisher":"U.S. Geological

The number and size of campsites decreased following the completion of Glen Canyon Dam in 1963 due to reductions of sediment that replenish sandbars and increases in vegetation cover caused by flow regulation. Campsite area continues to decrease despite the use of controlled floods to rebuild sandbars. We quantify the relative magnitude of factors that contribute to changes in campsite size, such as fluvial deposition and erosion, gullying, and vegetation expansion with analysis of four‐band aerial imagery and digital elevation models. Campsite area declined by 37% between 2002 and 2016 (an average of 161&nbsp;m</span><sup>2</sup><span>&nbsp;per site at long‐term monitoring sites). Two drivers contributed to campsite area change: (a) short‐term gains and losses associated with controlled floods and flood‐deposit erosion and (b) long‐term one‐directional loss of campsite area caused by vegetation encroachment. There was more erosion and slope change at sites in critical reaches—sections of river where campsites are infrequent or in high demand—than in noncritical reaches. Vegetation continues to expand at campsites under flow regulation, particularly in noncritical reaches. Although controlled floods have contributed to short‐term increases in sandbar size, long‐term increases in campsite area have not occurred because of sandbar erosion between controlled floods and vegetation expansion. Manual vegetation removal may need to be considered in future management strategies.</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/rra.3349","usgsCitation":"Hadley, D., Grams, P.E., and Kaplinski, M.A., 2018, Quantifying geomorphic and vegetation change at sandbar campsites in response to flow regulation and controlled floods, Grand Canyon National Park, Arizona: River Research and Applications, v. 34, no. 9, p. 1208-1218, https://doi.org/10.1002/rra.3349.","productDescription":"11 p.","startPage":"1208","endPage":"1218","ipdsId":"IP-092936","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":357670,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States ","state":"Arizona","otherGeospatial":"Grand Canyon National Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -114.0106201171875,\n              35.70414710206052\n            ],\n            [\n              -111.50848388671875,\n              35.70414710206052\n            ],\n            [\n              -111.50848388671875,\n              36.89499795802219\n            ],\n            [\n              -114.0106201171875,\n              36.89499795802219\n            ],\n            [\n              -114.0106201171875,\n              35.70414710206052\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"34","issue":"9","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2018-09-04","publicationStatus":"PW","scienceBaseUri":"5bc02fa2e4b0fc368eb5393d","contributors":{"authors":[{"text":"Hadley, Daniel R. 0000-0002-0701-7580","orcid":"https://orcid.org/0000-0002-0701-7580","contributorId":196522,"corporation":false,"usgs":false,"family":"Hadley","given":"Daniel R.","affiliations":[],"preferred":false,"id":746077,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Grams, Paul E. 0000-0002-0873-0708 pgrams@usgs.gov","orcid":"https://orcid.org/0000-0002-0873-0708","contributorId":1830,"corporation":false,"usgs":true,"family":"Grams","given":"Paul","email":"pgrams@usgs.gov","middleInitial":"E.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":746076,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kaplinski, Matthew A.","contributorId":139210,"corporation":false,"usgs":false,"family":"Kaplinski","given":"Matthew","email":"","middleInitial":"A.","affiliations":[{"id":12698,"text":"Northern Arizona University","active":true,"usgs":false}],"preferred":false,"id":746078,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Some aquifer tests also were reinterpreted multiple times because the wells had not been defined uniquely. Previous databases and reports identified wells by different borehole names, reported various depths to top and bottom of open intervals, and used inconsistent wetted-aquifer thicknesses, which were coupled with inappropriate analytical methods to interpret aquifer-test data.</span></div><div><span><br data-mce-bogus=\"1\"></span></div><div><span>This work standardized the reporting of single-well aquifer-test results at Pahute Mesa and vicinity.

Because occurrences of dynamic triggering provide in-situ information of the stress-state of a responding site, a more complete global picture of susceptible crustal environments becomes an important component of seismic hazard evaluations. Here we 1) review evidence for tectonic regime dependence of dynamic triggering susceptibility in the shallow brittle crust, and 2) explore triggering susceptibility at Alaskan volcanoes. We search for significant increases in seismicity rates at 19 Alaskan volcanic areas between 2006 and 2013 within 3 days following regional and teleseismic earthquakes of magnitude 7 and greater. We find evidence for 12 triggered responses at 9 volcanoes, but no evidence for triggered responses following hundreds of other earthquakes. The most impressive response was that of Pavlof Volcano to the 2011 M</span><sub>W</sub><span>&nbsp;9.0 Tohoku-Oki earthquake. Our results suggest that triggered responses are difficult to predict, as they do not depend on background seismicity rates or amplitude of incident&nbsp;seismic waves&nbsp;from distant earthquakes. Taken together, observational and theoretical evidence suggests that dynamic triggering occurs in all tectonic environments. So far however, it appears to be more common in extensional and transtensional environments and regions with high pore-fluid pressure than in compressional and transpressional environments. Although some volcanic and geothermal areas may be primed for dynamic earthquake triggering, volcanoes in Alaska are relatively insensitive. The weak and variable responses of Alaskan volcanoes suggest that triggering susceptibility depends on time varying crustal conditions, such as the state of stress and distribution of&nbsp;pore pressure. Results also indirectly suggest that eruption triggering by distant earthquakes is unlikely in Alaska over the time scale of days.</span></div></div></div></div></div><div

We explore terrain metric similarity with changes in scale, both grain and extent, and examine how selecting the best measures is sensitive to changes in application. There are three types of topographic measures: 1) those that relate to orientation for approximating solar input, 2) those that capture variability in terrain configuration, and 3) those that provide metrics about landform features. Many biodiversity hotspots and predators have been found to coincide with areas of complexity, yet most complexity measures cannot differentiate between terrain steepness and uneven and broken terrain. Currently characterizing terrain in landscape-level analyses can be challenging, especially at coarser spatial resolutions but developing methods that improve landscape-level assessments include multivariate approaches and the use of neighborhood statistics. Some measures are sensitive to the spatial grain of calculation, the physiography of the landscape, and the scale of application. We show which measures have the potential to be multi-collinear, and illustrate with a case study how the selection of the best measures can change depending on the question at hand using mountain lion (Puma concolor) occurrence data. The case study showed a combination of infrequently employed metrics, such as view-shed analysis and focal statistics, outperform more commonly employed singular metrics. The use of focal statistics as a measure of topographic complexity shows promise for improving how mountain lions use terrain features.</p>","language":"English","publisher":"Horizon Research Publishing Corporation","doi":"10.13189/eer.2018.060501","usgsCitation":"Ironside, K.E., Mattson, D.J., Arundel, T.R., Theimer, T., Holton, B., Peters, M., Edwards, T., and Hansen, J.R., 2018, Geomorphometry in landscape ecology: Issues of scale, physiography, and application: Environment and Ecology Research, v. 6, no. 5, p. 397-412, https://doi.org/10.13189/eer.2018.060501.","productDescription":"16 p.","startPage":"397","endPage":"412","ipdsId":"IP-084757","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":468443,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.13189/eer.2018.060501","text":"Publisher Index Page"},{"id":357136,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6","issue":"5","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5b98a269e4b0702d0e842e82","contributors":{"authors":[{"text":"Ironside, Kirsten E. 0000-0003-1166-3793 kironside@usgs.gov","orcid":"https://orcid.org/0000-0003-1166-3793","contributorId":3379,"corporation":false,"usgs":true,"family":"Ironside","given":"Kirsten","email":"kironside@usgs.gov","middleInitial":"E.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":744527,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mattson, David J.","contributorId":191920,"corporation":false,"usgs":false,"family":"Mattson","given":"David","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":744528,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Arundel, Terence R. 0000-0003-0324-4249 tarundel@usgs.gov","orcid":"https://orcid.org/0000-0003-0324-4249","contributorId":139242,"corporation":false,"usgs":true,"family":"Arundel","given":"Terence","email":"tarundel@usgs.gov","middleInitial":"R.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":744529,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Theimer, Tad","contributorId":191914,"corporation":false,"usgs":false,"family":"Theimer","given":"Tad","affiliations":[],"preferred":false,"id":744530,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Holton, Brandon","contributorId":191915,"corporation":false,"usgs":false,"family":"Holton","given":"Brandon","affiliations":[],"preferred":false,"id":744531,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Peters, Michael","contributorId":191919,"corporation":false,"usgs":false,"family":"Peters","given":"Michael","email":"","affiliations":[],"preferred":false,"id":744532,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Edwards, Thomas C.

Formaldehyde concentrations ≥37&nbsp;mg/L increased TAN and nitrite nitrogen concentrations, and nitrification did not recover to pre‐exposure concentrations up to 8&nbsp;day postexposure. On the basis of those results, a second trial was conducted. Stable biofilters were exposed once or on four consecutive days to 9.25 or 18.5&nbsp;mg/L formaldehyde.

These fractures are sometimes displayed dramatically as so-called “A-tents”, whereby relatively thin rock sheets push upwards and fracture, forming tent-like voids beneath the ruptured sheets. The origin and formation of such features has been a topic of considerable interest and analysis for over a century. Here we show that thermally-induced stresses, coincident with particularly hot days during particularly hot years, were responsible for recent (2014-2016) energetic ruptures of rock sheets forming a granitic exfoliation dome in California, USA. Through a three-year field effort, we found that subcritical fracture occurred due to diurnal and seasonal cumulative thermal stresses. However, our analyses also indicate that subsequent critical fracture could only have been reached if thermal stresses acted in concert with existing tectonic stresses. Thus, we offer a superposition triggering mechanism (background tectonic stresses with cyclic thermal stresses) to explain these rock fracture features.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the 52nd U.S. Rock Mechanics/Geomechanics Symposium","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"52nd U.S. Rock Mechanics/Geomechanics Symposium","conferenceDate":"June 17-20, 2018","conferenceLocation":"Seattle, WA","language":"English","publisher":"American Rock Mechanics Association (ARMA)","usgsCitation":"Collins, B.D., Stock, G.M., and Eppes, M., 2018, Thermally induced fracture of macroscale surficial granite sheets, <i>in</i> Proceedings of the 52nd U.S. Rock Mechanics/Geomechanics Symposium, Seattle, WA, June 17-20, 2018, 7 p.","productDescription":"7 p.","ipdsId":"IP-096183","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":357025,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5b98a269e4b0702d0e842e86","contributors":{"authors":[{"text":"Collins, Brian D. 0000-0003-4881-5359 bcollins@usgs.gov","orcid":"https://orcid.org/0000-0003-4881-5359","contributorId":149278,"corporation":false,"usgs":true,"family":"Collins","given":"Brian","email":"bcollins@usgs.gov","middleInitial":"D.","affiliations":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":741296,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stock, Greg M.","contributorId":88593,"corporation":false,"usgs":true,"family":"Stock","given":"Greg","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":741297,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Eppes, Martha C.","contributorId":202874,"corporation":false,"usgs":false,"family":"Eppes","given":"Martha C.","affiliations":[{"id":36544,"text":"Univ. of North Carolina, Charlotte","active":true,"usgs":false}],"preferred":false,"id":741298,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We concur that regulatory and messaging consistency is a beneficial mutual goal and suggest that it’s time to reexamine the biophysical and social scientific basis for such guidance, historical precedents, alternative management options, and where there are needs for flexibility. We also identify possible additional research needs and suggest alternative actions based on the current body of research.</span></p>","language":"English","publisher":"WILD Foundation","usgsCitation":"Marion, J.L., Wimpey, J., and Lawhorn, B., 2018, Conflicting messages about camping near waterbodies in wilderness: A review of the scientific basis and need for flexibility: International Journal of Wilderness, v. 24, no. 2, HTML Document.","productDescription":"HTML Document","ipdsId":"IP-098643","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":357445,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":357381,"type":{"id":15,"text":"Index Page"},"url":"https://ijw.org/2018-conflicting-messages-about-camping-near-waterbodies-in-wilderness/"}],"volume":"24","issue":"2","publishingServiceCenter":{"id":10,"text":"Baltimore PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5bc02fa2e4b0fc368eb53941","contributors":{"authors":[{"text":"Marion, Jeffrey L. 0000-0003-2226-689X jeff_marion@usgs.gov","orcid":"https://orcid.org/0000-0003-2226-689X","contributorId":3614,"corporation":false,"usgs":true,"family":"Marion","given":"Jeffrey","email":"jeff_marion@usgs.gov","middleInitial":"L.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":745186,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wimpey, Jeremy","contributorId":189354,"corporation":false,"usgs":false,"family":"Wimpey","given":"Jeremy","affiliations":[],"preferred":false,"id":745188,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lawhorn, Ben","contributorId":207913,"corporation":false,"usgs":false,"family":"Lawhorn","given":"Ben","email":"","affiliations":[{"id":37663,"text":"Leave No Trace Center for Outdoor Ethics","active":true,"usgs":false}],"preferred":false,"id":745187,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

A prominent wilderness therapy organization utilizes vast tracts of the Grand Staircase-Escalante National Monument (GSENM) for programming. This study examines the specific ecological impacts stemming from the program in GSENM, concurrently with a content analysis of the training procedures administered by the organization. Results emphasize the need to improve education, training, and mitigation measures to minimize impacts stemming from this and other wilderness therapy programs in GSENM, as well as other wilderness areas in which these programs operate.","language":"English","publisher":"WILD Foundation","usgsCitation":"Romo, A., Marion, J.L., Wimpey, J., Taff, D., and Schwartz, F., 2018, Understanding and mitigating wilderness therapy impacts: The Grand Staircase-Escalante National Monument case study: International Journal of Wilderness, v. 24, no. 2, HTML Document.","productDescription":"HTML Document","ipdsId":"IP-096515","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":357444,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":357414,"type":{"id":15,"text":"Index Page"},"url":"https://ijw.org/2018-understanding-and-mitigating-wilderness-therapy-impacts/"}],"country":"United States","otherGeospatial":"Grand Staircase-Escalante National Monument","volume":"24","issue":"2","publishingServiceCenter":{"id":10,"text":"Baltimore PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5bc02fa2e4b0fc368eb53943","contributors":{"authors":[{"text":"Romo, Amelia","contributorId":207977,"corporation":false,"usgs":false,"family":"Romo","given":"Amelia","email":"","affiliations":[],"preferred":false,"id":745319,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Marion, Jeffrey L. 0000-0003-2226-689X jeff_marion@usgs.gov","orcid":"https://orcid.org/0000-0003-2226-689X","contributorId":3614,"corporation":false,"usgs":true,"family":"Marion","given":"Jeffrey","email":"jeff_marion@usgs.gov","middleInitial":"L.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":745318,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wimpey, Jeremy","contributorId":207952,"corporation":false,"usgs":false,"family":"Wimpey","given":"Jeremy","affiliations":[{"id":32905,"text":"Applied Trails Research","active":true,"usgs":false}],"preferred":false,"id":745321,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Taff, Derrick","contributorId":207951,"corporation":false,"usgs":false,"family":"Taff","given":"Derrick","email":"","affiliations":[{"id":7260,"text":"Pennsylvania State University","active":true,"usgs":false}],"preferred":false,"id":745320,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Schwartz, Forrest","contributorId":207953,"corporation":false,"usgs":false,"family":"Schwartz","given":"Forrest","email":"","affiliations":[{"id":7260,"text":"Pennsylvania State University","active":true,"usgs":false}],"preferred":false,"id":745322,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
