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}]}}

Weathering profiles are characterized by a 5–50</span><span>&nbsp;</span><span>m thick regolith that consists of saprolitized Saganaga Tonalite and Paulson Lake succession basaltic metavolcanic rocks retaining rock structure, which is cross-cut by a major unconformity surface marking development of a successor basin infilled with alluvial deposits. The regolith and unconformity are overlain by thick conglomerate deposits that contain both intrabasinal (saprock) as well as extrabasinal detritus. Thin-section microscopy and electron microprobe analyses reveal extensive hydrolysis and sericitization of feldspars, exfoliation and chloritization of biotite, and weathering of Fe-Mg silicates and Cu-Fe sulfides; weathering of Fe-Ti oxides was relatively less intense than for other minerals and evidence was found for precipitation of Fe oxides.

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}]}}

The stable hydrogen isotope composition of hair has been used in ecological studies to track migrations of mammals as well as for forensic and archaeological purposes to determine the provenance of human remains or the recent geographic life trajectory of living people. Measurement of the total hydrogen isotopic composition of a hair sample yields a composite value comprised of both metabolically informative, non-exchangeable hydrogen and exchangeable hydrogen, with the latter reflecting ambient or sample preparation conditions. Neither of these attributes is directly measurable, and the non-exchangeable hydrogen composition is obtained by estimation using a commonly applied mathematical expression incorporating sample measurements obtained from two distinct equilibration procedures. This commonly used approach treats the fraction of exchangeable hydrogen as a mixing ratio, with a minimal procedural fractionation factor assumed to be close or equal to 1. Instead, we propose to use full molar ratios to derive an expression for the non-exchangeable hydrogen composition explicitly as a function of both the procedural fractionation factor α and the molar hydrogen exchange fraction f<sub>E</sub>. We apply these derivations in a longitudinal study of a hair sample and demonstrate that the molar hydrogen exchange fraction f<sub>E</sub> should, like the procedural fractionation factor α, be treated as a process-dependent parameter, i.e. a reaction-specific constant. This is a counter-intuitive notion given that maximum theoretical values for the molar hydrogen exchange fraction f<sub>E</sub> can be calculated that are arguably protein-type specific and, as such, f<sub>E</sub> could be regarded as a compound-specific constant. We also make some additional suggestions for future approaches to determine the non-exchangeable hydrogen composition of hair and the use of standards.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Rapid Communications in Mass Spectrometry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/rcm.4854","issn":"09514198","usgsCitation":"Landwehr, J., Meier-Augenstein, W., and Kemp, H., 2011, A counter-intuitive approach to calculating non-exchangeable <sup>2</sup>H isotopic composition of hair: treating the molar exchange fraction f<sub>E</sub> as a process-related rather than compound-specific variable: Rapid Communications in Mass Spectrometry, v. 25, no. 2, p. 301-306, https://doi.org/10.1002/rcm.4854.","productDescription":"6 p.","startPage":"301","endPage":"306","costCenters":[{"id":633,"text":"Water Resources National Research Program","active":false,"usgs":true}],"links":[{"id":216291,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/rcm.4854"},{"id":244154,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"25","issue":"2","noUsgsAuthors":false,"publicationDate":"2010-12-28","publicationStatus":"PW","scienceBaseUri":"5059e39de4b0c8380cd46125","contributors":{"authors":[{"text":"Landwehr, J.M.","contributorId":39815,"corporation":false,"usgs":true,"family":"Landwehr","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":452971,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Meier-Augenstein, W.","contributorId":29664,"corporation":false,"usgs":true,"family":"Meier-Augenstein","given":"W.","affiliations":[],"preferred":false,"id":452970,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kemp, H.F.","contributorId":41241,"corporation":false,"usgs":true,"family":"Kemp","given":"H.F.","email":"","affiliations":[],"preferred":false,"id":452972,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Our analyses relied on aerial surveys of bark beetle outbreaks that occurred between 1991 and 2008. Occurrence points for each species were generated within polygons created from the aerial surveys. Current and projected climate scenarios were acquired from the WorldClim database and represented by 19 bioclimatic variables. We used Maxent modeling technique fit with occurrence points and current climate data to model potential beetle distributions and forest vulnerability. Three available climate models, each having two emission scenarios, were modeled independently and results averaged to produce two predictions for 2020 and two predictions for 2050 for each analysis. Environmental parameters defined by current climate models were then used to predict conditions under future climate scenarios, and changes in different species’ ranges were calculated. Our results suggested that the potential distribution for bark beetles under current climate conditions is extensive, which coincides with infestation trends observed in the last decade. Our results predicted that suitable habitats for the mountain pine beetle and pine engraver beetle will stabilize or decrease under future climate conditions, while habitat for the western pine beetle will continue to increase over time. The greatest increase in habitat area was for the western pine beetle, where one climate model predicted a 27% increase by 2050. In contrast, the predicted habitat of the mountain pine beetle from another climate model suggested a decrease in habitat areas as great as 46% by 2050. Generally, 2020 and 2050 models that tested the three climate scenarios independently had similar trends, though one climate scenario for the western pine beetle produced contrasting results. Ranges for all three species of bark beetles shifted considerably geographically suggesting that some host species may become more vulnerable to beetle attack in the future, while others may have a reduced risk over time.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.foreco.2011.03.036","issn":"03781127","usgsCitation":"Evangelista, P., Kumar, S., Stohlgren, T.J., and

Electronic tagging studies provide information on the spatial ecology, behavior and survival of fish in marine and freshwater systems. However, any surgical procedure, particularly one where a laparotomy is performed and the coelomic cavity is opened, has the potential to alter the survival, behavior or condition of the animal which can impair welfare and introduce bias. Given that management, regulatory and conservation decisions are based on the assumption that fish implanted with electronic tags have similar fates and behavior relative to untagged conspecifics, it is critical to ensure that best surgical practices are being used. Also, the current lack of standardized surgical procedures and reporting of specific methodological details precludes cross-study and cross-year analyses which would further progress the field of fisheries science. This compilation of papers seeks to identify the best practices for the entire intracoelomic tagging procedure including pre- and post-operative care, anesthesia, wound closure, and use of antibiotics. Although there is a particular focus on salmonid smolts given the large body of literature available on that group, other life-stages and species of fish are discussed where there is sufficient knowledge. Additional papers explore the role of the veterinarian in fish surgeries, the need for minimal standards in the training of fish surgeons, providing a call for more complete and transparent procedures, and identifying trends in procedures and research needs. Collectively, this body of knowledge should help to improve data quality (including comparability and repeatability), enhance management and conservation strategies, and maintain the welfare status of tagged fish.</span></p>","language":"English","publisher":"Springer Link","doi":"10.1007/s11160-010-9183-5","issn":"09603166","usgsCitation":"Brown, R., Eppard, M., Murchie, K., Nielsen, J.L., and Cooke, S.J., 2011, An introduction to the practical and ethical perspectives on the need to advance and standardize the intracoelomic surgical implantation of electronic tags in fish: Reviews in Fish Biology and Fisheries, v. 21, no. 1, p. 1-9, https://doi.org/10.1007/s11160-010-9183-5.","productDescription":"9 p.","startPage":"1","endPage":"9","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":244224,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216360,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s11160-010-9183-5"}],"volume":"21","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-12-30","publicationStatus":"PW","scienceBaseUri":"5059ea8ce4b0c8380cd48930","contributors":{"authors":[{"text":"Brown, R.S.","contributorId":68084,"corporation":false,"usgs":true,"family":"Brown","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":453167,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Eppard, M.B.","contributorId":9084,"corporation":false,"usgs":true,"family":"Eppard","given":"M.B.","email":"","affiliations":[],"preferred":false,"id":453164,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Murchie, K.J.","contributorId":28097,"corporation":false,"usgs":true,"family":"Murchie","given":"K.J.","email":"","affiliations":[],"preferred":false,"id":453165,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Nielsen, Jennifer L.","contributorId":43722,"corporation":false,"usgs":true,"family":"Nielsen","given":"Jennifer","email":"","middleInitial":"L.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":453168,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Cooke, S.

Daily nest-survival rate was positively related to maximum daily temperature during the nest interval and to density of large-diameter trees surrounding the nest tree. We developed a niche-based habitat suitability model (partitioned Mahalanobis distance) for nesting white-headed woodpeckers using remotely sensed data. Along with low elevation, high density of large trees, and low slope, our habitat suitability model suggested that interspersion–juxtaposition of low- and high-canopy cover ponderosa pine (</span><i>Pinus ponderosa</i><span>) patches was important for nest-site suitability. Cross-validation suggested the model performed adequately for management planning at a scale &gt;1 ha. Evaluation of mapped habitat suitability index (HSI) suggested that the maximum predictive gain (HSI = 0.36), where the number of nest locations are maximized in the smallest proportion of the modeled landscape, provided an objective initial threshold for identification of suitable habitat. However, managers can choose the threshold HSI most appropriate for their purposes (e.g., locating regions of low–moderate suitability that have potential for habitat restoration). Consequently, our habitat suitability model may be useful for managing dry coniferous forests for white-headed woodpeckers in central Oregon; however, model validation is necessary before our model could be applied to other locations.</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/jwmg.146","usgsCitation":"Hollenbeck, J.P., Saab, V.A., and Frenzel, R.W., 2011, Habitat suitability and nest survival of white-headed woodpeckers in unburned forests of Oregon: Journal of Wildlife Management, v. 75, no. 5, p. 1061-1071, https://doi.org/10.1002/jwmg.146.","productDescription":"11 p.","startPage":"1061","endPage":"1071","costCenters":[],"links":[{"id":246474,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"75","issue":"5","noUsgsAuthors":false,"publicationDate":"2011-06-03","publicationStatus":"PW","scienceBaseUri":"505a2f2de4b0c8380cd5cb64","contributors":{"authors":[{"text":"Hollenbeck, Jeff P. 0000-0001-6481-5354 jhollenbeck@usgs.gov","orcid":"https://orcid.org/0000-0001-6481-5354","contributorId":5130,"corporation":false,"usgs":true,"family":"Hollenbeck","given":"Jeff","email":"jhollenbeck@usgs.gov","middleInitial":"P.","affiliations":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":289,"text":"Forest and Rangeland Ecosys Science Center","active":true,"usgs":true}],"preferred":true,"id":455378,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Saab, Victoria A.","contributorId":82963,"corporation":false,"usgs":true,"family":"Saab","given":"Victoria","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":455377,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Frenzel, Richard W.","contributorId":42311,"corporation":false,"usgs":false,"family":"Frenzel","given":"Richard","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":455376,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Both formed in active andesite–dacite volcanic terranes. Fluid inclusion, stable isotope and geologic data show that lode deposits formed within 1500&nbsp;m of the paleo-surface as a consequence of the expansion of low-salinity, low-density magmatic vapor with very limited, if any, groundwater mixing. They are characterized by an initial ‘Sulfate’ Stage of advanced argillic wallrock alteration&nbsp;±&nbsp;alunite commonly with intense silicification followed by a ‘Sulfide’ Stage — a succession of discrete sulfide–sulfosalt veins that may be ore grade in gold and silver. Fluid inclusions in quartz formed during wallrock alteration have homogenization temperatures between 100 and over 500&nbsp;°C and preserve a record of a vapor-rich environment.</p><p id=\"sp0045\">Recent data for El Indio and similar deposits show that at the commencement of the Sulfide Stage, ‘condensation’ of Cu–As–S sulfosalt melts with trace concentrations of Sb, Te, Bi, Ag and Au occurred at &gt;&nbsp;600&nbsp;°C following pyrite deposition. Euhedral quartz crystals were simultaneously deposited from the vapor phase during crystallization of the vapor-saturated melt occurs to Fe-tennantite with progressive non-equilibrium fractionation of heavy metals between melt-vapor and solid. Vugs containing a range of sulfides, sulfosalts and gold record the changing composition of the vapor.</p><p id=\"sp0050\">Published fluid inclusion and mineralogical data are reviewed in the context of geological relationships to establish boundary conditions through which to trace the expansion of magmatic vapor from source to surface and consequent alteration and mineralization. Initially heat loss from the vapor is high resulting in the formation of acid condensate permeating through the wallrock. This Sulfate Stage alteration effectively isolates the expansion of magmatic vapor in subsurface fracture arrays from any external contemporary hydrothermal activity. Subsequent fracturing is localized by the embrittled wallrock to provide high-permeability fracture arrays that constrain vapor expansion with minimization of heat loss. The Sulfide Stage vein sequence is then a consequence of destabilization of metal-vapor species in response to depressurization and decrease in vapor density.</p><p id=\"sp0055\">The geology, mineralogy, fluid inclusion and stable isotope data and geothermometry for high-sulfidation, bulk-tonnage and lode deposits are quite different from those for epithermal gold–silver deposits such as McLaughlin, California that formed near-surface in groundwater-dominated hydrothermal systems where magmatic fluid has been diluted to less than about 30%. High sulfidation gold deposits are better termed ‘Solfataric Gold Deposits’ to emphasize this distinction. The magmatic-vapor expansion hypothesis also applies to the phenomenology of acidic geothermal systems in active volcanic systems and equivalent magmatic-vapor discharges on the flanks of submarine volcanoes.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.oregeorev.2010.11.003","issn":"01691368","usgsCitation":"Henley, R.W., and Berger, B.R., 2011, Magmatic-vapor expansion and the formation of high-sulfidation gold deposits: Chemical controls on alteration and mineralization: Ore Geology Reviews, v. 39, no. 1-2, p. 63-74, https://doi.org/10.1016/j.oregeorev.2010.11.003.","productDescription":"12 p.","startPage":"63","endPage":"74","costCenters":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":475185,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.oregeorev.2010.11.003","text":"Publisher Index Page"},{"id":244251,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216387,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.oregeorev.2010.11.003"}],"volume":"39","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4b51e4b0c8380cd69460","contributors":{"authors":[{"text":"Henley, Richard W.","contributorId":107193,"corporation":false,"usgs":true,"family":"Henley","given":"Richard","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":453169,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Berger, Byron R. bberger@usgs.gov","contributorId":1490,"corporation":false,"usgs":true,"family":"Berger","given":"Byron","email":"bberger@usgs.gov","middleInitial":"R.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":453170,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Such a gap was previously proposed to explain an abrupt change in megafloral assemblages in the northern Appalachian Basin and by extension across all of North America. Conodont-based correlation from the essentially complete low-shelf Midcontinent succession (distal from the highstand shoreline), through the mid-shelf Illinois Basin, to the high shelf of the Appalachian Basin (proximal to highstand shoreline) demonstrates that all major ∼400&nbsp;kyr cyclothem groupings in the Midcontinent are recognizable in the Illinois Basin. In the Appalachian Basin, however, the grouping at the base of the Missourian is represented only by paleosols and localized coal. The immediately preceding grouping was removed very locally by paleovalley incision, as is evident at the 7–11 Mine, Columbiana County, Ohio, from which the original megafloral data were derived. At the few localities where incised paleodrainage exists, there may be a gap of ∼1000&nbsp;kyr, but a gap of no more than ∼600&nbsp;kyr occurs elsewhere in the Appalachian Basin at that level and its magnitude progressively decreases westward into the Illinois (∼300&nbsp;kyr) and Midcontinent (&lt;200&nbsp;kyr) Basins. Thus, while a gap is present near the Desmoinesian–Missourian boundary in North America, it is typically more than an order of magnitude smaller than that originally proposed and is similar to the gaps inferred at sequence boundaries between cyclothems at many horizons in the Pennsylvanian of North America.</span></p>","language":"English","publisher":"Society for Sedimentary

After interpolation in latitude, the model can describe solar‐activity dependence and seasonal dependence of solar quiet daily variations (S) and lunar quiet daily variations (L). We performed a spherical harmonic analysis (SHA) on these S and L variations to examine average characteristics of the equivalent external current systems. We found three particularly noteworthy results. First, the total current intensity of the S current system is largely controlled by solar activity while its focus position is not significantly affected by solar activity. Second, we found that seasonal variations of the S current intensity exhibit north‐south asymmetry; the current intensity of the northern vortex shows a prominent annual variation while the southern vortex shows a clear semi‐annual variation as well as annual variation. Thirdly, we found that the total intensity of the L current system changes depending on solar activity and season; seasonal variations of the L current intensity show an enhancement during the December solstice, independent of the level of solar activity.</span></p>","language":"English","publisher":"American Geophysical

This is the first well-documented geologic slip rate between the Carrizo and creeping sections of the San Andreas fault. This rate is lower than Holocene measurements along the Carrizo Plain and rates implied by far-field geodetic measurements (∼35 mm/yr). However, the rate is consistent with historical slip rates, measured to the northwest, along the creeping section of the San Andreas fault (&lt;30 mm/yr). The paleoseismic exposures at the Miller's Field site reveal a pervasive fabric of clay shear bands, oriented clockwise oblique to the San Andreas fault strike and extending into the uppermost stratigraphy. This fabric is consistent with dextral aseismic creep and observations of surface slip from the 28 September 2004 M6 Parkfield earthquake. Together, this slip rate and deformation fabric suggest that the historically observed San Andreas fault slip behavior along the Parkfield section has persisted for at least a millennium, and that significant slip is accommodated by structures in a zone beyond the main San Andreas fault trace.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/G31498.1","issn":"00917613","usgsCitation":"Toke, N., Arrowsmith, J., Rymer, M.J., Landgraf, A., Haddad, D., Busch, M., Coyan, J., and Hannah, A., 2011, Late Holocene slip rate of the San Andreas fault and its accommodation by creep and moderate-magnitude earthquakes at Parkfield, California: Geology, v. 39, no. 3, p. 243-246, https://doi.org/10.1130/G31498.1.","productDescription":"4 p.","startPage":"243","endPage":"246","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":244219,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Parkfield","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.19018554687499,\n              34.813803317113155\n            ],\n            [\n              -118.57543945312501,\n              34.813803317113155\n            ],\n            [\n              -118.57543945312501,\n              36.80048816579081\n            ],\n            [\n              -121.19018554687499,\n              36.80048816579081\n            ],\n            [\n              -121.19018554687499,\n              34.813803317113155\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"39","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a44eae4b0c8380cd66eca","contributors":{"authors":[{"text":"Toke, N.A.","contributorId":76924,"corporation":false,"usgs":true,"family":"Toke","given":"N.A.","affiliations":[],"preferred":false,"id":452652,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Arrowsmith, J.R.","contributorId":88536,"corporation":false,"usgs":true,"family":"Arrowsmith","given":"J.R.","affiliations":[],"preferred":false,"id":452653,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rymer, Michael J. mrymer@usgs.gov","contributorId":1522,"corporation":false,"usgs":true,"family":"Rymer","given":"Michael","email":"mrymer@usgs.gov","middleInitial":"J.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":452654,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Landgraf, A.","contributorId":99796,"corporation":false,"usgs":true,"family":"Landgraf","given":"A.","email":"","affiliations":[],"preferred":false,"id":452655,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Haddad, D.E.","contributorId":45545,"corporation":false,"usgs":true,"family":"Haddad","given":"D.E.","email":"","affiliations":[],"preferred":false,"id":452649,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Busch, M.","contributorId":59268,"corporation":false,"usgs":true,"family":"Busch","given":"M.","email":"","affiliations":[],"preferred":false,"id":452650,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Coyan, J.","contributorId":41673,"corporation":false,"usgs":true,"family":"Coyan","given":"J.","affiliations":[],"preferred":false,"id":452648,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Hannah, A.","contributorId":62431,"corporation":false,"usgs":true,"family":"Hannah","given":"A.","email":"","affiliations":[],"preferred":false,"id":452651,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Two Archean domains are recognized: the eastern Antongil-Masora domain and the central Antananarivo domain, the latter with distinctive belts of metamafic gneiss and schist (Tsaratanana Complex). In the eastern domain, the period of early crust formation is extended to the Paleo-Mesoarchean (3.32-3.15 Ga) and a supracrustal sequence (Fenerivo Group), deposited at 3.18 Ga and metamorphosed at 2.55 Ga, is identified. In the central domain, a Neoarchean period of high-grade metamorphism and anatexis that affected both felsic (Betsiboka Suite) and mafic gneisses (Tsaratanana Complex) is documented. We propose, therefore, that the Antananarivo domain was amalgamated within the Greater Dharwar Craton (India + Madagascar) by a Neoarchean accretion event (2.55-2.48 Ga), involving emplacement of juvenile igneous rocks, high-grade metamorphism, and the juxtaposition of disparate belts of mafic gneiss and schist (metagreenstones). The concept of the \"Betsimisaraka suture\" is dispelled and the zone is redefined as a domain of Neoproterozoic metasedimentary (Manampotsy Group) and metaigneous rocks (Itsindro-Imorona Suite) formed during a period of continental extension and intrusive igneous activity between 840 and 760 Ma. Younger orogenic convergence (560-520 Ma) resulted in east-directed overthrusting throughout south Madagascar and steepening with local inversion of the domain in central Madagascar. Along part of its length, the Manampotsy Group covers the boundary between the eastern and central Archean domains and is overprinted by the Angavo-Ifanadiana high-strain zone that served as a zone of crustal weakness throughout Cretaceous to Recent times.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Earth Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/E10-034","issn":"00084077","usgsCitation":"Tucker, R.D., Roig, J., Delor, C., Amlin, Y., Goncalves, P., Rabarimanana, M., Ralison, A., and Belcher, R., 2011, Neoproterozoic extension in the greater dharwar craton: A reevaluation of the \"betsimisaraka suture\" in madagascar: Canadian Journal of Earth Sciences, v. 48, no. 2, p. 389-417, https://doi.org/10.1139/E10-034.","startPage":"389","endPage":"417","numberOfPages":"29","costCenters":[],"links":[{"id":216493,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/E10-034"},{"id":244367,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"48","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6459e4b0c8380cd72999","contributors":{"authors":[{"text":"Tucker, R.

This chronology yields a range of average recurrence intervals between 116 and 221 yr, depending on assumptions, with a best-estimate average recurrence interval of 180 yr. The most recent earthquake occurred c.1690, more than 300 yr ago, suggesting that this stretch of the fault has accumulated a large amount of tectonic stress and is likely to rupture in the near future, assuming the fault follows a stress renewal model. This study also establishes the timing of the past 5-6 highstands of ancient Lake Cahuilla since A.D. 800.We found that earthquakes do not tend to occur at any particular stage in the lake cycle.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Seismological Society of America","publisherLocation":"El Cerrito, CA","doi":"10.1785/0120100050","issn":"00371106","usgsCitation":"Philibosian, B., Fumal, T., and Weldon, R., 2011, San Andreas fault earthquake chronology and Lake Cahuilla history at Coachella, California: Bulletin of the Seismological Society of America, v. 101, no. 1, p. 13-38, https://doi.org/10.1785/0120100050.","productDescription":"26 p.","startPage":"13","endPage":"38","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":475445,"rank":10001,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://resolver.caltech.edu/CaltechAUTHORS:20110301-100935325","text":"External Repository"},{"id":438830,"rank":10000,"type":{"id":30,"text":"Data Release"},"url":"https://doi.org/10.5066/P9KAL9R3","text":"USGS data release","linkHelpText":"Full-resolution photomosaics of trench walls from the 2006 paleoseismic study of the San Andreas Fault at Coachella, California"},{"id":244337,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216466,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120100050"}],"country":"United States","state":"California","city":"Coachella","otherGeospatial":"Lake Cahuilla","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.216439,33.642068 ], [ -116.216439,33.730059 ], [ -116.078373,33.730059 ], [ -116.078373,33.642068 ], [ -116.216439,33.642068 ] ] ] } } ] }","volume":"101","issue":"1","noUsgsAuthors":false,"publicationDate":"2011-01-26","publicationStatus":"PW","scienceBaseUri":"505ab09ae4b0c8380cd87bcb","contributors":{"authors":[{"text":"Philibosian, B.","contributorId":103115,"corporation":false,"usgs":true,"family":"Philibosian","given":"B.","affiliations":[],"preferred":false,"id":452540,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fumal, T.","contributorId":46692,"corporation":false,"usgs":true,"family":"Fumal","given":"T.","affiliations":[],"preferred":false,"id":452538,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Weldon, R.","contributorId":99307,"corporation":false,"usgs":true,"family":"Weldon","given":"R.","affiliations":[],"preferred":false,"id":452539,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

TRIGRS (transient rainfall infiltration and grid-based regional slope-stability analysis) is a USGS landslide prediction model, coded in Fortran, that accounts for the influences of hydrology, topography, and soil physics on slope stability. In this study, we quantitatively evaluate the spatiotemporal predictability of a Matlab version of TRIGRS (MaTRIGRS) in the Blue Ridge Mountains of Macon County, North Carolina where Hurricanes Ivan triggered widespread landslides in the 2004 hurricane season. High resolution digital elevation model (DEM) data (6-m LiDAR), USGS STATSGO soil database, and NOAA/NWS combined radar and gauge precipitation are used as inputs to the model. A local landslide inventory database from North Carolina Geological Survey is used to evaluate the MaTRIGRS’ predictive skill for the landslide locations and timing, identifying predictions within a 120-m radius of observed landslides over the 30-h period of Hurricane Ivan’s passage in September 2004. Results show that within a radius of 24&nbsp;m from the landslide location about 67% of the landslide, observations could be successfully predicted but with a high false alarm ratio (90%). If the radius of observation is extended to 120&nbsp;m, 98% of the landslides are detected with an 18% false alarm ratio. This study shows that MaTRIGRS demonstrates acceptable spatiotemporal predictive skill for landslide occurrences within a 120-m radius in space and a hurricane-event-duration (h) in time, offering the potential to serve as a landslide warning system in areas where accurate rainfall forecasts and detailed field data are available. The validation can be further improved with additional landslide information including the exact time of failure for each landslide and the landslide’s extent and run out length.</span></p>","language":"English","publisher":"Springer Link","doi":"10.1007/s11069-010-9670-y","issn":"0921030X","usgsCitation":"Liao, Z., Hong, Y., Kirschbaum, D., Adler, R., Gourley, J., and Wooten, R., 2011, Evaluation of TRIGRS (transient rainfall infiltration and grid-based regional slope-stability analysis)'s predictive skill for hurricane-triggered landslides: A case study in Macon County, North Carolina: Natural Hazards, v. 58, no. 1, p. 325-339, https://doi.org/10.1007/s11069-010-9670-y.","productDescription":"15 p.","startPage":"325","endPage":"339","costCenters":[],"links":[{"id":246117,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218133,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s11069-010-9670-y"}],"country":"United States","state":"North Carolina","county":"Macon","otherGeospatial":"Blue Ridge Mountains","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-83.6811,35.2794],[-83.6644,35.2835],[-83.4961,35.3004],[-83.4889,35.3043],[-83.4866,35.3044],[-83.4734,35.2993],[-83.4667,35.299],[-83.4583,35.3016],[-83.4493,35.315],[-83.4378,35.3217],[-83.4284,35.3247],[-83.414,35.3183],[-83.4101,35.3193],[-83.4003,35.3269],[-83.3885,35.3277],[-83.3654,35.3283],[-83.3599,35.333],[-83.3507,35.3288],[-83.338,35.3336],[-83.3317,35.3198],[-83.323,35.315],[-83.3126,35.2821],[-83.3149,35.2698],[-83.3083,35.26],[-83.2984,35.2548],[-83.2898,35.236],[-83.2862,35.2329],[-83.272,35.2292],[-83.2485,35.2326],[-83.2431,35.2382],[-83.2365,35.2425],[-83.2274,35.24],[-83.2178,35.2253],[-83.2246,35.1606],[-83.2126,35.1564],[-83.1962,35.1409],[-83.1868,35.1307],[-83.1758,35.1083],[-83.1494,35.0954],[-83.1451,35.0878],[-83.1459,35.08],[-83.1565,35.0775],[-83.1718,35.0671],[-83.1699,35.0608],[-83.1499,35.054],[-83.1341,35.0381],[-83.1314,35.0268],[-83.1224,35.013],[-83.1129,35.0141],[-83.1094,35.011],[-83.1076,35.0079],[-83.1052,35.002],[-83.1256,35.0014],[-83.4584,34.9946],[-83.4836,34.9946],[-83.4844,34.9946],[-83.4879,34.9981],[-83.5101,35.0047],[-83.5218,35.0026],[-83.5232,35.0093],[-83.5201,35.0154],[-83.5214,35.0185],[-83.5409,35.0393],[-83.5455,35.0414],[-83.55,35.0413],[-83.5573,35.0406],[-83.5656,35.0503],[-83.5628,35.0631],[-83.5664,35.0685],[-83.5838,35.0798],[-83.5854,35.0888],[-83.5998,35.097],[-83.613,35.1011],[-83.6165,35.1046],[-83.6165,35.116],[-83.6201,35.1218],[-83.6198,35.1282],[-83.6239,35.1303],[-83.6277,35.1279],[-83.6337,35.1232],[-83.6382,35.1244],[-83.6391,35.1308],[-83.636,35.1372],[-83.6384,35.139],[-83.647,35.1423],[-83.6503,35.1531],[-83.6572,35.1575],[-83.6589,35.157],[-83.6609,35.1519],[-83.6654,35.1504],[-83.6713,35.157],[-83.678,35.1568],[-83.6875,35.1542],[-83.6943,35.1554],[-83.7026,35.152],[-83.7128,35.1544],[-83.7265,35.1462],[-83.7387,35.1553],[-83.7319,35.1646],[-83.7301,35.1752],[-83.7243,35.1817],[-83.7122,35.1871],[-83.7102,35.1935],[-83.724,35.1994],[-83.7254,35.2039],[-83.7222,35.2081],[-83.715,35.212],[-83.708,35.2181],[-83.6971,35.2248],[-83.6929,35.2322],[-83.6916,35.24],[-83.6934,35.2426],[-83.6988,35.2479],[-83.6861,35.2665],[-83.6811,35.2794]]]},\"properties\":{\"name\":\"Macon\",\"state\":\"NC\"}}]}","volume":"58","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-12-01","publicationStatus":"PW","scienceBaseUri":"505a0c25e4b0c8380cd52a5a","contributors":{"authors":[{"text":"Liao, Z.","contributorId":107137,"corporation":false,"usgs":true,"family":"Liao","given":"Z.","email":"","affiliations":[],"preferred":false,"id":454917,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hong, Y.","contributorId":67343,"corporation":false,"usgs":true,"family":"Hong","given":"Y.","email":"","affiliations":[],"preferred":false,"id":454915,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kirschbaum, D.","contributorId":41686,"corporation":false,"usgs":true,"family":"Kirschbaum","given":"D.","affiliations":[],"preferred":false,"id":454913,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Adler, R.F.","contributorId":31243,"corporation":false,"usgs":true,"family":"Adler","given":"R.F.","email":"","affiliations":[],"preferred":false,"id":454912,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Gourley, J.J.","contributorId":45557,"corporation":false,"usgs":true,"family":"Gourley","given":"J.J.","affiliations":[],"preferred":false,"id":454914,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Wooten, R.","contributorId":86610,"corporation":false,"usgs":true,"family":"Wooten","given":"R.","email":"","affiliations":[],"preferred":false,"id":454916,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Our study provides new constraints on models governing landslide motion. We monitored landslide deformation with temporary deployments of a 29-element prism array surveyed by a robotic theodolite and an 88-station seismic network that complemented permanent extensometers and environmental instrumentation. Aseismic deformation observations show that large blocks of the landslide move steadily at approximately centimeters per day, possibly punctuated by variations of a few millimeters, while localized transient slip episodes of blocks less than a few tens of meters across occur frequently. We recorded a rich variety of seismic signals, nearly all of which originated outside the monitoring network boundaries or from the side-bounding strike-slip faults. The landslide basal surface beneath our seismic network likely slipped almost completely aseismically. Our results provide independent corroboration of previous inferences that dilatant strengthening along sections of the side-bounding strike-slip faults controls the overall landslide motion, acting as seismically radiating brakes that limit acceleration of the aseismically slipping basal surface. Dilatant strengthening has also been invoked in recent models of transient slip and tremor sources along crustal- and plate-scale faults suggesting that the landslide may indeed be a useful natural laboratory for testing predictions of specific mechanisms that control fault slip at all scales.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research B: Solid Earth","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","publisherLocation":"Washington, D.C.","doi":"10.1029/2011JB008304","issn":"01480227","usgsCitation":"Gomberg, J., Schulz, W., Bodin, P., and Kean, J., 2011, Seismic and geodetic signatures of fault slip at the Slumgullion Landslide Natural Laboratory: Journal of Geophysical Research B: Solid Earth, v. 116, no. 9, 20 p.; B09404, https://doi.org/10.1029/2011JB008304.","productDescription":"20 p.; B09404","costCenters":[{"id":234,"text":"Earthquake Hazards Program","active":true,"usgs":true},{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":246543,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218523,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2011JB008304"}],"country":"United States","state":"Colorado","county":"Hinsdale County","otherGeospatial":"Slumgullion Landslide","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -107.5857,37.4209 ], [ -107.5857,38.1468 ], [ -106.9978,38.1468 ], [ -106.9978,37.4209 ], [ -107.5857,37.4209 ] ] ] } } ] }","volume":"116","issue":"9","noUsgsAuthors":false,"publicationDate":"2011-09-17","publicationStatus":"PW","scienceBaseUri":"505b8aeee4b08c986b31748d","contributors":{"authors":[{"text":"Gomberg, J.","contributorId":95994,"corporation":false,"usgs":true,"family":"Gomberg","given":"J.","email":"","affiliations":[],"preferred":false,"id":455404,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schulz, W.","contributorId":6641,"corporation":false,"usgs":true,"family":"Schulz","given":"W.","email":"","affiliations":[],"preferred":false,"id":455401,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bodin, P.","contributorId":29554,"corporation":false,"usgs":true,"family":"Bodin","given":"P.","email":"","affiliations":[],"preferred":false,"id":455402,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kean, J.","contributorId":62447,"corporation":false,"usgs":true,"family":"Kean","given":"J.","affiliations":[],"preferred":false,"id":455403,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

From 2005 to 2008, we outfitted fourteen bobcats with GPS collars that collected spatially explicit locations from individuals every 4</span><span>&nbsp;</span><span>h for 3–4</span><span>&nbsp;</span><span>months. Kernel home range techniques were used to estimate home range size and boundaries, and to quantify the utilization distribution (UD), which is a spatially explicit, topographic mapping of how different areas within the home range are used. We then used GIS methods to quantify both biotic (e.g. habitat types, stream density) and abiotic (e.g. slope) resources within each bobcat’s home range. Across bobcats, upper 20th UD percentiles (core areas) had 18% less agriculture, 42% less development, 26% more bobcat habitat (shrub, deciduous, coniferous forest, and wetland cover types), and 33% lower road density than lower UD percentiles (UD valleys). For each bobcat, we used Akaike’s Information Criterion (AIC) to evaluate and compare 24 alternative Resource Utilization Functions (hypotheses) that could explain the topology of the individual’s UD. A model-averaged population-level Resource Utilization Function suggested positive responses to shrub, deciduous, coniferous forest, and wetland cover types within 1</span><span>&nbsp;</span><span>km of a location, and negative responses to roads and mixed forest cover types within 1</span><span>&nbsp;</span><span>km of a location. Applying this model-averaged function to each pixel in the study area revealed habitat suitability for bobcats across the entire study area, with suitability scores ranging between −1.69 and 1.44, where higher values were assumed to represent higher quality habitat. The southern Champlain Valley, which contained ample wetland and shrub habitat, was a concentrated area of highly suitable habitat, while areas at higher elevation areas were less suitable. Female bobcat home ranges, on average, had an average habitat suitability score of near 0, indicating that home ranges consisted of both beneficial and detrimental habitat types. We discuss the application of habitat suitability mapping and home range requirements for bobcat conservation and landscape scale management.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.biocon.2011.06.026","issn":"00063207","usgsCitation":"Donovan, T., Freeman, M., Abouelezz, H., Royar, K., Howard, A., and Mickey, R., 2011, Quantifying home range habitat requirements for bobcats (Lynx rufus) in Vermont, USA: Biological Conservation, v. 144, no. 12, p. 2799-2809, https://doi.org/10.1016/j.biocon.2011.06.026.","productDescription":"11 p.","startPage":"2799","endPage":"2809","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":242881,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215107,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.biocon.2011.06.026"}],"country":"United States","state":"Vermont","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -73.32275390625,\n              42.779275360241904\n            ],\n            [\n              -72.50976562499999,\n              42.74701217318067\n            ],\n            [\n              -72.35595703125,\n              43.27720532212024\n            ],\n            [\n              -71.96044921875,\n              44.37098696297173\n            ],\n            [\n              -71.43310546875,\n              44.49650533109348\n            ],\n            [\n              -71.43310546875,\n              45.02695045318546\n            ],\n            [\n              -73.32275390625,\n              45.089035564831036\n            ],\n            [\n              -73.5205078125,\n              44.308126684886126\n            ],\n            [\n              -73.388671875,\n              43.739352079154706\n            ],\n            [\n              -73.32275390625,\n              43.50075243569041\n            ],\n            [\n              -73.32275390625,\n              42.779275360241904\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"144","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a91cfe4b0c8380cd80492","contributors":{"authors":[{"text":"Donovan, Therese tdonovan@usgs.gov","contributorId":171599,"corporation":false,"usgs":true,"family":"Donovan","given":"Therese","email":"tdonovan@usgs.gov","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"preferred":true,"id":450796,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Freeman, M.","contributorId":56349,"corporation":false,"usgs":true,"family":"Freeman","given":"M.","email":"","affiliations":[],"preferred":false,"id":450795,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Abouelezz, H.","contributorId":52806,"corporation":false,"usgs":true,"family":"Abouelezz","given":"H.","affiliations":[],"preferred":false,"id":450793,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Royar, Kim","contributorId":9886,"corporation":false,"usgs":true,"family":"Royar","given":"Kim","affiliations":[],"preferred":false,"id":450791,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Howard, A.","contributorId":54392,"corporation":false,"usgs":true,"family":"Howard","given":"A.","email":"","affiliations":[],"preferred":false,"id":450794,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mickey, R.","contributorId":44725,"corporation":false,"usgs":true,"family":"Mickey","given":"R.","email":"","affiliations":[],"preferred":false,"id":450792,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}
