Egg Mass Counts from Foothill Yellow-Legged Frogs (Rana boylii) in California from 1992-2021 Egg Mass Counts from Foothill Yellow-Legged Frogs (Rana boylii) in California from 1992-2021
We compiled time series of egg mass counts (an index of adult female abundance) from Rana boylii populations in 36 focal streams and fit a Multiple Population Viability Analysis (MPVA) model to quantify how streamflow metrics, stream temperature, and surrounding land cover affect population growth. In addition, data on streamflow, stream temperature, and surrounding land cover for each...
Survey Results for Temblor Legless Lizards (Anniella alexanderae) in the San Joaquin Valley of California, 2022 and 2023 Survey Results for Temblor Legless Lizards (Anniella alexanderae) in the San Joaquin Valley of California, 2022 and 2023
Locations of sites at which U.S. Geological Survey (USGS) biologists surveyed for Temblor legless lizards (Anniella alexanderae) in 2022 and 2023 and the results of those surveys. At the time of the species description, little was known about the distribution of the Temblor legless lizard beyond a few localities. Surveys were designed to gather information on the distribution of Temblor...
Data to Support Hierarchical Models and Decision Support Maps to Guide Management of Subsidized Avian Predator Densities Data to Support Hierarchical Models and Decision Support Maps to Guide Management of Subsidized Avian Predator Densities
We combined approximately 28,000 raven point count surveys with data from more than 900 sage-grouse nests between 2009 and 2019 within the Great Basin, USA. We modeled variation in raven density using a Bayesian hierarchical distance sampling approach with environmental covariates on detection and abundance. Concurrently, we modeled sage-grouse nest survival using a hierarchical frailty...
Greater Sage-Grouse Adult and Nest Observations Before and After Wildfire in Northwest Nevada (2008-2019) Greater Sage-Grouse Adult and Nest Observations Before and After Wildfire in Northwest Nevada (2008-2019)
Wildfire events are becoming more frequent and severe on a global scale. Rising temperatures, prolonged drought, and the presence of pyrophytic invasive grasses are contributing to the degradation of native vegetation communities. Within the Great Basin region of the Western United States, increasing wildfire frequency is transforming the ecosystem toward a higher degree of homogeneity...
Code for a hierarchical model of raven densities linked with sage-grouse nest survival to help guide management of subsidized avian predators, version 1.0 Code for a hierarchical model of raven densities linked with sage-grouse nest survival to help guide management of subsidized avian predators, version 1.0
This repository includes R code to conduct hierarchical density surface modeling of common raven (Corvus corax) point count data and hierarchical shared frailty modeling of Greater sage-grouse (Centrocercus urophasianus) nest fates. The model components are quantitatively linked, such that estimates of raven density from the hierarchical distance sampling component are spatially...
Conservation Planning Tool for the Bi-State Distinct Population Segment of Greater Sage-grouse Conservation Planning Tool for the Bi-State Distinct Population Segment of Greater Sage-grouse
The Bi-State conservation planning tool provides a science-based approach for prioritizing pinyon (Pinus spp.) and juniper (Juniperus osteosperma, J. occidentalis), hereafter, 'conifer', removal to improve habitat for greater sage-grouse (Centrocercus urophasianus) in the Bi-State Distinct Population Segment (DPS, U.S. Fish and Wildlife Service 2010). Conifer negatively affects sage...
Nest Attendance, Incubation Constancy, and Onset of Incubation in Dabbling Ducks Nest Attendance, Incubation Constancy, and Onset of Incubation in Dabbling Ducks
This dataset includes daily nest attendance (proportion of time females spent at the nest), incubation constancy (proportion of time females maintained their nests at nest-specific incubation temperatures), nest temperature variation, and the duration of individual incubation bouts for three species of dabbling ducks (mallard, gadwall, and cinnamon teal) nesting in Suisun Marsh...
Stem and Needle Growth for Whitebark Pine in the Sierra Nevada Stem and Needle Growth for Whitebark Pine in the Sierra Nevada
These data represent stem growth, needle length growth, and carbon stable isotope ratios from whitebark pine at 27 sites in the Sierra Nevada of California. Values for stem growth were derived from increment cores, processed following standard methods. Needle characteristics were captured for individual trees across all years needles were present on the internodes. Needle length was...
Predictive Maps of Fuel Break Effectiveness by Treatment Type and Underlying Resilience to Disturbance and Resistance to Invasion Across the Western U.S. Predictive Maps of Fuel Break Effectiveness by Treatment Type and Underlying Resilience to Disturbance and Resistance to Invasion Across the Western U.S.
Escalated wildfire activity within the western U.S. has widespread societal impacts and long-term consequences for the imperiled sagebrush (Artemisia spp.) biome. Shifts from historical fire regimes and the interplay between frequent disturbance and invasive annual grasses may initiate permanent state transitions as wildfire frequency outpaces sagebrush communities' innate capacity to...
Western Pond Turtle (Emys [Actinemys] marmorata) Observations at Point Reyes National Seashore and Golden Gate National Recreation Area Western Pond Turtle (Emys [Actinemys] marmorata) Observations at Point Reyes National Seashore and Golden Gate National Recreation Area
These data represent incidental observations of western pond turtles (Emys [Actinemys] marmorata) collected by the U.S. Geological Survey, Western Ecological Research Center, at Point Reyes National Seashore and Golden Gate National Recreation Area between 1993 and 2014. These data do not have associated survey effort, and are intended to represent incidental observations, rather than a...
Mercury, Cortisol, and Blood Biomarkers in Adult Female Northern Elephant Seals from 2011 to 2021 Mercury, Cortisol, and Blood Biomarkers in Adult Female Northern Elephant Seals from 2011 to 2021
This dataset represents 179 unique adult female northern elephant seals that were sampled between 2011 and 2021 during four different life history states (early breeding, late breeding, early molting, and late molting) at the Ano Nuevo colony in California, USA. Some individual seals were sampled multiple times, resulting in a total of 313 tissue samples. Tissue samples were collected...
Elevation and Mangrove Cover Projections under Sea-Level Rise Scenarios at J.N. Ding Darling National Wildlife Refuge, Sanibel Island, Florida, 2020-2100 Elevation and Mangrove Cover Projections under Sea-Level Rise Scenarios at J.N. Ding Darling National Wildlife Refuge, Sanibel Island, Florida, 2020-2100
Elevation projections from the WARMER-Mangroves model for J N. "Ding" Darling National Wildlife Refuge across a range of sea-level rise scenarios (53, 115, and 183 cm by 2100). The model was calibrated using dated soil cores sampled from the basin hydrologic zone. These data support the following publication: Buffington, K.J., Thorne, K.M., Krauss, K.W., Conrad, J.K., Drexler, J.Z., and...
