Data

This contains data from 1,030 surveys returned in 2017 from across the United States. Data were collected via a mail-out survey stratified by the population of each state. Data collected include nature-related activity participation, attitudes and barriers to hunting and birdwatching, knowledge of others who hunt and birdwatch, preferred birds, involvement in conservation activities, preferences f

These data were collected from Burmese pythons removed from the Florida everglades as part of invasive-species management. After euthanasia, we sexed (male or female) and measured the snout-vent length (SVL; cm) and total body mass (g) for each python. We also measured total fat mass (g) by removing all visible fat bodies from the coelomic cavity and weighing this mass. For a subset of specimens,

These bat location estimates have been reported by Bogan and others (In press) and come in the form of a GIS shape file. Three species of nectar-feeding phyllostomid bats migrate north from Mexico into deserts of the United States (U.S.) each spring and summer to feed on blooms of columnar cacti and century plants (Agave spp). However, the habitat needs of these important desert pollinators are p

The data archive contains the aerial photographs and channel delineations used in our analysis. The images have been geo-referenced to the 1995 digital orthophoto quarter quadrangles as described by Miller and Friedman (2009). The separate images for each year can be viewed as a composite along with that year's channel delineation using a geographic information system (GIS). The 2003 IKONOS satell

Deformed wing virus (DWV) is a major pathogen of concern to apiculture, and recent reports have indicated the local predominance and potential virulence of recombinants between DWV and a related virus, Varroa destructor virus 1 (VDV). However, little is known about the frequency and titer of VDV and recombinants relative to DWV generally. In this study, I assessed the relative occurrence and titer

These data provide information about vegetation structure and composition associated with Arizona Grasshopper Sparrow territories, nest plots, and random transects on two study sites - Audubon Appleton-Whittell Research Ranch and BLM Las Cienegas National Conservation Area (NCA) - Davis Pasture - in southeastern Arizona. Data were collected from 2009 through 2013. These are data associated with Ru

This is a comma separated values (csv) file used to conduct the logistic quantile regression analyses in R provided by Cade et al. (2017. Logistic quantile regression provides improved estimates for bounded avian counts: A case study of California spotted owl fledgling production. The Auk: Ornithological Advances. In press). The data set consists of records of California spotted owl fledgling c

These data include descriptions of all roadside segments surveyed, including GPS waypoints and verbal descriptions for each point (every half mile), survey data collected on roadside surveys in 2003-2005 in the months of July and August, along roads within the known breeding range of the Arizona Grasshopper Sparrow (Ammodramus savannarum ammolegus).

This data bundle contains some of the inputs, all of the processing instructions and all outputs from two VisTrails/SAHM workflow. These models specifically include field data of locations with >40% cover of cheatgrass (presence) and

Data on the occurrence of plague epizootics in colonies of black-tailed prairie dogs, Pawnee National Grassland, Colorado 1982-2005. Data are derived from annual prairie dog surveys conducted by staff of the Pawnee National Grassland, U.S. Forest Service. The data includes information on the year of sampling, colony identification, UTM coordinates of colony centroids, weather (precipitation and te

This data release includes video files and image-processing results used to conduct the analyses of hibernation patterns in groups of bats reported by Hayman et al. (2017), "Long-term video surveillance and automated analyses reveal arousal patterns in groups of hibernating bats. Thermal-imaging surveillance video cameras were used to observe little brown bats (Myotis lucifugus) in a cave in Virg

Ammodramus savannarum ammolegus (commonly referred to as the Arizona Grasshopper Sparrow) occurs in the desert and plains grasslands of southeastern Arizona, southwestern New Mexico, and northern Sonora, Mexico. Although a subspecies of conservation concern, this data was produced as part of the first intensive study of its life history and breeding ecology, providing baseline data and facilitatin
