Data

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...

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...

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...

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...

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...

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...

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...

This dataset describes incubation recess timing for mallard and gadwall hens nesting in Grizzly Island Wildlife Area in breeding seasons 2015-2017. It includes the start time, end time, and duration of recesses. This data supports the following publication: Croston, R., Hartman, C.A., Herzog, M.P., Casazza, M.L., Feldheim, C.L. and Ackerman, J.T., 2020. Timing, frequency, and duration of

These data show the multilocus genotypes, gender, and midline carapace length (MCL) for desert tortoises (Gopherus agassizii) sampled in the central portion of the Mojave desert tortoise range. This data supports the following publication: Dutcher, K.E., Vandergast, A.G., Esque, T.C., Mitelberg, A., Matocq, M.D., Heaton, J.S. and Nussear, K.E., Genes in space: what Mojave Desert tortoise

These data were collected to quantify oak mortality during the 2014-2017 drought. 30 tenth hectare drought plots were established throughout the blue oak woodland of Sequoia National Park. Information on species, size, and mortality were collected for all standing trees in each plot. In addition, two long-term 2.25 ha plots were established, in which the same data were collected.

Due to recent interest in developing offshore wind energy infrastructure around the main Hawaiian Islands (MHI), U.S. Geological Survey Western Ecological Research Center (USGS-WERC) partnered with the Bureau of Ocean Energy Management (BOEM) from 2013-2016 to study breeding Hawaiian seabird distributions, habitat utilizations, and ranging behaviors within near-island and outer...

This datasets summarizes small mammal trapping efforts that USGS San Francisco Bay Estuary Field Station has led, co-led, or supervised, to detect and monitor the endangered salt marsh harvest mouse (Reithrodontomys raviventris) in the northern reaches of San Francisco Bay from 1998-2014. As the salt marsh harvest mouse is listed as endangered under the Endangered Species Act, sensitive...
