Database of invasive annual grass spatial products for the western United States January 2010 to February 2021 Database of invasive annual grass spatial products for the western United States January 2010 to February 2021
Invasive annual grasses (IAGs) present a persistent challenge for the ecological management of rangelands, particularly the imperiled sagebrush biome in western North America. Cheatgrass (Bromus tectorum), medusahead (Taeniatherum caput-medusae), and Ventenata spp. are spreading across sagebrush rangelands and already occupy at least 200,000 kilometers squared (km sq.) of the...
Winter herbaceous utilization by elk and bison in the Great Sand Dunes National Park ecosystem of the San Luis Valley, Colorado, 2006 to 2008 Winter herbaceous utilization by elk and bison in the Great Sand Dunes National Park ecosystem of the San Luis Valley, Colorado, 2006 to 2008
These data represent 2 years of plant clipping data in areas with elk plus bison and areas of elk only in the San Luis Valley of Colorado, USA from 2006-2008. Clipping plots were measured (clipped) in meadow sites, herbaceous riparian sites, and willow communities. We clipped 1/4 m2 (meter-squared) rings inside and outside of 1-m2 grazing cages, as well as within large ungulate...
Simulation models for buffelgrass and alternative management strategies for Saguaro National Park, AZ Simulation models for buffelgrass and alternative management strategies for Saguaro National Park, AZ
This is a spatially-explicit state-and-transition simulation model of buffelgrass dynamics and alternative management actions in Saguaro National Park, AZ. Buffelgrass is an invasive grass spreading in the park. This work built on previous efforts that first developed a state and transition simulation model linked to FARSITE fire behavior model to describe buffelgrass dynamics in the...
Status and Trends of North American Bats Summer Occupancy Analysis 2010-2019 Data Release Status and Trends of North American Bats Summer Occupancy Analysis 2010-2019 Data Release
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...
Data on Utah prairie dog body condition and reproductive success, Awapa Plateau, Utah, USA, 2013-2016 Data on Utah prairie dog body condition and reproductive success, Awapa Plateau, Utah, USA, 2013-2016
Data on body condition and reproduction of Utah prairie dogs at 5 colonies on the Awapa Plateau, Utah, USA, June-August 2013-2016. Utah prairie dogs were live-trapped and sampled on 5 colonies. We recorded the age (juvenile/adult) and mass (nearest 5 grams) of each prairie dog and marked its ears and body with metal tags and passive integrated transponders, respectively, for permanent
Sagebrush recovery analyzed with a dynamic reference approach in southwestern Wyoming, USA 1985-2018 Sagebrush recovery analyzed with a dynamic reference approach in southwestern Wyoming, USA 1985-2018
Identifying ecologically relevant reference sites is important for evaluating ecosystem recovery, but the relevance of references that are temporally static is unclear in the context of vast landscapes with disturbance and environmental contexts varying over space and time. This question is pertinent for landscapes dominated by sagebrush (Artemisia spp.) which face a suite of threats...
Photo-documented sequences from 01 Jun 2021 - 30 Aug 2021 showing novel interactions between intraguild predators in southern Florida, USA, bobcat and Burmese python Photo-documented sequences from 01 Jun 2021 - 30 Aug 2021 showing novel interactions between intraguild predators in southern Florida, USA, bobcat and Burmese python
Entire photo-documented sequence from 01 June 2021-09 September 2021, including novel interactions between intraguild predators in southern Florida - the native bobcat (Lynx rufus) and the invasive Burmese python (Python bivittatus). A bobcat depredated an unguarded Burmese python nest and subsequently the python exhibited nest defense behavior following the return of both animals to the...
Exogenous and endogenous factors influence invasive reptile movement at multiple scales, 2018 - 2019 Exogenous and endogenous factors influence invasive reptile movement at multiple scales, 2018 - 2019
These data reflect movement values for brown treesnakes from Guam that were translocated (moved by humans) to new locations or were resident (left in place) on Guam. The data are related to the specimen's treatment group, individual values, locations and other details affiliated with radio telemetry based acquisition and positional changes by the individual snakes across tracking events...
Riparian woody stem densities and landscape variables along the South Platte River, Colorado, United States, 2011-2016 Riparian woody stem densities and landscape variables along the South Platte River, Colorado, United States, 2011-2016
This data set includes riparian woody stem counts, stem densities and landscape variables collected at 28 sites along the South Platte River, Colorado, United States from 2011-2016. Riparian woody stem densities were collected in the field during 2011, 2015, and 2016, and include the species Ulmus pumila, Populus deltoides, Salix amygdaloides, Fraxinus pennsylvanica, and Elaeagnus...
Gene annotations for the hoary bat (Lasiurus [Aeorestes] cinereus) and alignments with other bat gene sets for evolutionary analysis Gene annotations for the hoary bat (Lasiurus [Aeorestes] cinereus) and alignments with other bat gene sets for evolutionary analysis
Bats of the genus Lasiurus occur throughout the Americas and have diversified into at least 20 species among three subgenera. The hoary bat (Lasiurus cinereus, or synonymously, Aeorestes cinereus) is highly migratory and ranges farther across North America than any other wild mammal. Despite the ecological importance of this species as a major insect predator, and the particular...
Data on the efficacy of deltamethrin flea control with small rodents on prairie dog colonies in Montana and Utah, 2001-2004 Data on the efficacy of deltamethrin flea control with small rodents on prairie dog colonies in Montana and Utah, 2001-2004
Data on the efficacy of deltamethrin flea control with small rodents on prairie dog colonies in Montana and Utah, 2001-2004. Data were collected on 12 colonies of 3 prairie dog (PD) species at 5 sites in Montana and Utah. PD species included black-tailed PDs (Cynomys ludovicianus, BTPDs), Utah PDs (C. parvidens, UPDs), and white-tailed PDs (C. leucurus, WTPDs). Sample sizes from 6 small...
Presence and abundance data and models for four invasive plant species Presence and abundance data and models for four invasive plant species
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...
