Classification of Waterfowl Habitat, and Quantification of Interannual Space Use and Movement Distance from Primary Roosts to Night Feeding Locations by Waterfowl in California for October - March of 2015 through 2018

Technological advancements in Global Positioning System (GPS) telemetry markers allow almost real-time observation of waterfowl movements and habitat selection. Telemetry data on ducks marked with GPS transmitters can be used to evaluate performance of remote sensing data (for example, dynamic open-water maps produced by Point Blue Conservation Science) for classifying habitats that are flooded an

Spatially-explicit predictive maps of greater sage-grouse nest selection integrated with nest survival in Nevada and northeastern California, USA

We applied spatially-explicit models to a spatiotemporally robust dataset of greater sage-grouse (Centrocercus urophasianus) nest locations and fates across wildfire-altered sagebrush ecosystems of the Great Basin ecoregion, western USA. Using sage-grouse as a focal species, we quantified scale-dependent factors driving nest site selection and nest survival across broad spatial scales in order to

Code and Data Files to Construct an Integral Projection Model for Giant Gartersnakes (Thamnophis gigas) in the Sacramento Valley, California, 1995-2017

This dataset includes data on the growth, fecundity, and survival of Giant Gartersnakes (Thamnophis gigas) in the Sacramento Valley of California from 1995-2017. In addition, the dataset includes R code to replicate the Integral Projection Model construction and analysis presented in the paper "Demographic drivers of population growth in a threatened snake" by Rose et al. published in Journal of W

Feeding observations of intertidal black abalone at monitored sites around San Nicolas Island, California and local distribution of Macrocystis pyrifera based on surface canopy maps

The data set includes feeding observations of black abalone (Haliotis cracherodii) at long-term intertidal monitoring sites around San Nicolas Island, California from 1982 - 2019. This includes site locations, sites, date of observation, observed food items, and abalone shell length when available. Seasonal (spring and fall) GIS maps of giant kelp (Macrocystis pyrifera) canopy distributions from t

Vegetation type conversion in chaparral in San Diego County, California, USA between 1953 and 2016

This dataset contains data pertaining to ground surface cover in a 30 meter radius around a random selection of points within San Diego County, California. These data were obtained from aerial imagery for the years 1953 and 2016 and were used to assess changes in cover type over time. These data support the following publication: Syphard, A.D., Brennan, T.J. and Keeley, J.E., 2019. Extent a

Least Bell's Vireo Habitat Suitability Model for California (2019)

This habitat model was developed to identify suitable habitat for the federally-endangered least Bell's vireo (Vireo bellii pusillus) across its current and historic range in California. The vireo disappeared from most of its range by the 1980s, remaining only in small populations in southern California. Habitat protection and management since the mid-1980s has led to an increase in southern Calif

Nest data for white-faced Ibis in Bear River Migratory Bird Refuge, Great Salt Lake, Utah in summer 2012

Nest monitoring data of white-faced ibis. Data were collected at seven day intervals and provide information on success and failure of the nest during that interval. Summary vegetation and habitat data were also collected at the nest. These data support the following publication: Mark P. Herzog, Ackerman, Joshua T., Hartman, C. Alex, and Browers, Howard, 2020, Nesting ecology of White-faced

Fire Caused Tree Mortality in Western US National Parks (2018)(ver. 2.0, February 2020)

This data consists of observations of individual trees that were subjected to prescribed fire in western US national parks. Information on individual trees include measurements of tree size, competition, and fire-caused damage. The data also includes estimates of plot-level vapor pressure deficit anomaly before fire. These data support the following publication: Van Mantgem, P.J., Falk, D.A., Wil

Mercury and selenium concentrations in bird eggs at Great Salt Lake, Utah

These metadata provide data used to examine mercury and selenium concentrations in eggs of birds breeding in wetlands of the Great Salt Lake ecosystem, Utah, particularly at Bear River Migratory Bird Refuge. Eggs were salvaged during 2010 - 2012 and include 33 species of birds. These data support the following publication: Ackerman, J.T., Herzog, M.P., Hartman, C.A., Isanhart, J., Herring,

Data maps of predicted raven density and areas of potential impact to nesting sage-grouse within sagebrush ecosystems of the North American Great Basin

These data represent predicted common raven (Corvus corax) density (ravens/square-km) derived from random forest models given field site unit-specific estimates of raven density that were obtained from hierarchical distance sampling models at 43 field site units within the Great Basin region, USA. Fifteen landscape-level predictors summarizing climate, vegetation, topography and anthropogenic foot

Coachella Valley Fringe-Toed Lizard (Uma inornata) Capture Data (2017 and 2018)

This dataset includes location, field measurements, and descriptions of 330 Uma inornata sampled for the research study entitled "Sampling Across 20 Years (1996-2017) Reveals Loss of Diversity and Genetic Connectivity in the Coachella Valley Fringe-Toed Lizard (Uma inornata)". Field sampling occurred between March and September of 2017 and between April and June of 2018. Lizards were located by vi
