Plant composition, geomorphic conditions and sediment properties before (2010) and after (2012) a 40 year return period flood (December 2010) at multiple transects within four reaches in the lower Virgin River, Nevada. The data contains four .csv files: localization (UTM coordinates of the transects), vegetation and geomorphology, species codes and sediment quality
This dataset provides the winter bird transect survey data collected on seven sites in southeastern Arizona during the winters (January - March) of 1999-2001; and for two of those seven sites during the winters of 2003-2005.
Here we present the map of probable suitable habitat for Triple-ribbed milkvetch (Astragalus tricarinatus). The data indicate both how many models predicted each location to be suitable for the species, and the average standardized habitat suitability score for each location.Data are presented at a spatial resolution of 10 m pixels, which was required to harmonize the original model inputs. However, maps of suitable habitat should be used at a resolution no smaller than 360 m (i.e., 36 pixels x 36 pixels), which corresponds with the resolution of the coarsest model input. This product can be used to inform future conservation, planning, and management actions in the California desert. Complete methods and other...
Here we present the map of potential suitable habitat for Parish’s phacelia (Phacelia parishii). The data indicate both how many models predicted each location to be potentially suitable for the species and the average standardized habitat suitability score for each location.Data are presented at a spatial resolution of 10 m pixels, which was required to harmonize the original model inputs. However, maps of suitable habitat should be used at a resolution no smaller than 360 m (i.e., 36 pixels x 36 pixels), which corresponds with the resolution of the coarsest model input. These data are intended to be used only to target future plant surveys in areas where new occurrences are most likely to benefit future habitat...

This file describes three datasets used to evaluate individual traits in brown treesnakes and how they affect susceptibility to toxicant applications. This file references three data sets that include 'Guam GROUND', SURVTOX', and 'HMU NWFN TRT.' Guam GROUND reference to snakes encountered during visual surveys on Guam and whether they were located on the ground or arboreal. SURVTOX refers to a known fate study of telemetered snakes that either survived or died during an application of toxic baits. HMU NWFN TRT refers to the demography of snakes captured pre and post-toxicant treatment.

The sagebrush ecosystem spans over 175 million acres in the western United States, and is biologically, culturally, and economically significant to the country. Many disturbances including prolonged drought, pinyon-juniper encroachment, and cycles of invasive grasses and wildfire, pose significant threats to the resilience of the sagebrush biome. To conserve the sagebrush biome and promote community and economic sustainability, the Department of the Interior’s bureaus and offices are working together with many public and private partners to implement a “defend and grow the core” approach to conserve remaining intact sagebrush habitat and ecosystem functions, as well as restore other habitat types which are important...
We developed habitat suitability models for four invasive plant species of concern to Department of Interior land management agencies. We generally followed the modeling workflow developed in Young et al. 2020, but developed models both for two data types, where species were present and where they were abundant. We developed models using five algorithms with VisTrails: Software for Assisted Habitat Modeling [SAHM 2.1.2]. We accounted for uncertainty related to sampling bias by using two alternative sources of background samples, and constructed model ensembles using the 10 models for each species (five algorithms by two background methods) for four different thresholds. This data bundle contains the presence and...
We developed habitat suitability models for occurrence of three invasive riparian woody plant taxa of concern to Department of Interior land management agencies, as well as for three dominant native riparian woody taxa. Study taxa were non-native tamarisk (saltcedar; Tamarix ramosissima, Tamarix chinensis), Russian olive (Elaeagnus angustifolia) and Siberian elm (Ulmus pumila) and native plains/Fremont cottonwood (Populus deltoides ssp. monilifera and ssp. wislizenii, Populus fremontii), narrowleaf cottonwood (Populus angustifolia), and black cottonwood (Populus balsamifera ssp. trichocarpa and ssp. balsamifera). We generally followed the modeling workflow developed in Young et al. 2020. We developed models using...

This data release contains the results from the North American Bat Monitoring Program's report titled 'Status and Trends of North American Bats Summer Occupancy Analysis 2010-2019'. Specifically, these data include tabular data and geospatial data for the species-specific results related to the status and trends of 12 bat species at multiple spatial scales including: 10 km x 10 km grid cells, state/province/territories, and range-wide across the geographic extent of monitoring data for each species (i.e., across 'modeled species ranges'). They were produced using an analytical pipeline supported by web-based infrastructure for integrating continental scale bat monitoring data (stationary acoustic, mobile acoustic,...

Management intended to benefit a target species may also affect non-target species that co-occur over space and time. Pinyon jay (Gymnorhinus cyanocephalus) populations experienced long-term declines and rely on habitat that could be lost to conifer removal programs for greater sage-grouse (Centrocercus urophasianus). Using 13 years of point count data (2008-2020) collected across the western United States and a suite of relevant covariates for habitat, we fit a hierarchical model to characterize and predict pinyon jay densities and evaluate population trends. The resulting maps include pinyon jay density at the beginning (PIJA_2008_PredictedDensity.tif) and end (PIJA_2020_PredictedDensity.tif) of our study period,...
We deployed 30 trap stations consisting of three combinations: isolated bird-lure traps, isolated mouse-lure traps, or paired stations to evaluate snake capture as a function of lure. At the paired stations, we included two traps: one bird-lure trap and one mouse-lure trap. All stations were at least 60 meters (m) apart and each of the station treatments was replicated 10 times. Traps at paired stations ranged from 1.7 to 6.7 m apart (mean 3.22 ± 0.46) depending on availability of vegetation from which to suspend traps. Both mouse-lure traps and bird-lure traps were adapted from standard modified commercial minnow traps composed of 6 millimeter (mm) galvanized steel mesh. The traps were operational for 67 trap nights...
These data are from a study of wild horses and burros wearing radio collars in a captive facility in Oklahoma, USA, for one year. We also evaluated radio transmitter tags (braided into the mane and tails of horses but not burros). We recorded behavior, body condition score, and effects of collars on the necks of horses and burros wearing radio collars and of horses and burros not wearing collars (controls), and recorded any behavioral effects from small radio transmitters on the mane and tails of horses to evaluate effects. These data provide recorded results of behavior, body condition score, and any physical neck effects from radio collars, during weekly and monthly monitoring sessions from February 2015 to March...

Thermal data collected from iButton temperature loggers implanted into research animals (Argentine giant tegus) and in their surrounding environment. Tegus undergo winter dormancy (hibernation) to cope with colder temperatures, and we studied the thermal habits of wild tegus within their invaded range in southern Florida, USA. We used radiotelemetry and trail cameras to verify dates of above-ground behaviors (active, basking, non-hibernating) and used temperature dataloggers to monitor surface (2 sun-exposed [Te] and 1 shaded [Ts]), 3 ambient (Ta), 19 subsurface ground (Th), and 22 internal body (Tb) temperatures of a population of free-ranging tegus over several seasons (46 weeks from 2015-2016). We recorded tegu...
