BioLake bioclimatic variables based on ERA5-Land lake temperature estimates 1991-2020 BioLake bioclimatic variables based on ERA5-Land lake temperature estimates 1991-2020

These BioLake raster data provide global estimates (~10.0 x 12.4 km resolution) of twelve bioclimatic variables based on estimated lake temperature. Eleven of these twelve variables (BioLake01 - BioLake11) are estimated for each of three lake strata: lake mix (surface) layer, lake bottom, and total lake water column. These eleven variables correspond to CHELSA (Climatologies at high...

Biological and chemical data from laboratory toxicity exposures of rainbow trout to four wildland fire retardants Biological and chemical data from laboratory toxicity exposures of rainbow trout to four wildland fire retardants

We determined the acute toxicity of four wildland fire retardants (Phos-Chek 259-Fx, Phos-Chek MVP-Fx, and Phos-Chek LC-95A-Fx, and Phos-Chek LC-95A-R) to two life stages (swim-up fry and young juveniles) of rainbow trout in standardized hard and soft water. The measure of acute toxicity was expressed as both the 96-hour median lethal concentration (96-h LC50, based on mortality) and 96...

Biological and chemical data from laboratory toxicity exposures of wildland fire retardants to Rainbow Trout Biological and chemical data from laboratory toxicity exposures of wildland fire retardants to Rainbow Trout

We measured Survival endpoints for juvenile rainbow trout (Oncorhynchus mykiss) in response to exposure to wildland fire retardants. Exposures were less than 24 hours. We documented time to mortality hourly through 12 hours of exposure and again at 24 hours. This data set includes data for three current use fire retardants from the US Forest Service Qualified Products List (Phos-Chek 259...

Biological Indicators and Mercury Concentrations in Smallmouth Bass Biological Indicators and Mercury Concentrations in Smallmouth Bass

Biological indicators including morphometric (length, weight), age, sex and health indicators including organismal (health assessment index, condition factor), organ (hepatosomatic index, gonadosomatic index), cellular (intersex, parasite density, macrophage aggregate density), subcellular (plasma vitellogenin, estradiol, testosterone, 11-keto testosterone) and molecular (hepatic...

Biological N-cycling data from soils collected along an elevation gradient in the CO Front Range (2018-2019) (ver. 2.0, November 2024) Biological N-cycling data from soils collected along an elevation gradient in the CO Front Range (2018-2019) (ver. 2.0, November 2024)

Atmospheric deposition of reactive nitrogen (Nr) can impact the soil microbial community structure and function and thus ecosystem processing and export of nutrients. Ecosystem response to atmospheric inputs of nitrogen depends on several factors, including elevational climate conditions (freeze/thaw cycles, precipitation), geology, soil and vegetation type, N speciation and microbial...

Biological soil crust and vascular plant data from Horse Heaven Hills, Washington, measured in 1999 and remeasured in 2020 Biological soil crust and vascular plant data from Horse Heaven Hills, Washington, measured in 1999 and remeasured in 2020

This dataset contains biocrust lichen and moss cover at 186 plots at Horse Heaven Hills in Washington, USA. These data were measured by Jeanne Ponzetti in 1999 and remeasured by Heather Root in 2020. In addition to the biocrust data, we include site data such as elevation, location, wildfire history, and cover classes of dominant plants, rock and soil.

Biophysical drivers for predicting the distribution and abundance of invasive yellow sweet clover in the Northern Great Plains Biophysical drivers for predicting the distribution and abundance of invasive yellow sweet clover in the Northern Great Plains

Yellow sweetclover (Melilotus officinalis; YSC), an invasive biennial legume, bloomed throughout the Northern Great Plains (NGP) following greater-than-average precipitation during 2018-2019. YSC can increase nitrogen (N) levels and potentially cause broad changes in the composition of native plant species communities. There is little knowledge of the drivers behind its spatiotemporal...

Black Bayou Hydrologic Restoration (CS-27): 2018 land-water classification Black Bayou Hydrologic Restoration (CS-27): 2018 land-water classification

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...

Blacklegged tick nymph densities, tickborne pathogen prevalence, and white-tailed deer densities in eight national parks in the eastern United States from 2014-2022 Blacklegged tick nymph densities, tickborne pathogen prevalence, and white-tailed deer densities in eight national parks in the eastern United States from 2014-2022

The data presented here are blacklegged tick nymph densities, white-tailed deer densities, and Borrelia burgdorferi (causative agent of Lyme disease) prevalences for eight national parks in the eastern United States from 2014-2022.

Body composition data of grizzly bears in the Greater Yellowstone Ecosystem 2000-2020 Body composition data of grizzly bears in the Greater Yellowstone Ecosystem 2000-2020

Understanding evolutionary processes that drive population dynamics is critical in ecology. Measuring the performance-density relationship in long-lived mammalian species demands long-term data, limiting the ability to observe such mechanisms. We tested density-dependent (intrinsic) and density-independent (extrinsic) drivers of body composition of grizzly bears (Ursus arctos) in the...
