Data

This dataset contains sample information about the origin of the Desmognathus wrighti and Plethodon jordani salamanders collected from Great Smoky Mountains National Park and sequenced, and their corresponding SNP genotype data. These data were used to examine patterns of genomic structure of these two salamander species within Great Smoky Mountains National Park. The raw sequence data...

These data were collected using distance sampling methods (point counts) and visual assessment of land cover and habitat along pre-determined driving routes in Texas during April and May 2016.

We conducted ground-based surveys at 589 randomly selected 16-ha plots on the Yukon-Kuskokwim Delta, Alaska during 2015-2016. The plots were selected using a stratified random sampling plan in an area of 35,769 square km divided into 8 physiographic strata. The population totals from the stratified random design estimators were adjusted using detection ratios derived with a double...

Datset includes necropsy-based observations including length, weight, sex, visible abnormalities; cellular or histopathological changes including neoplastic and preneoplastic skin and liver lesions; age; transcript abundance of hepatic genes associated with contaminant exposure, carcinogenesis, stress and immune responses and the white sucker hepatitis B virus. These were documented in...

The Ecology Section at the USGS, EESC, S. O. Conte Research Laboratory studied brook trout in a small coastal stream (Stanley Brook) from 2006 - 2013. The goal was to understand the mechanisms and consequences of anadromoy, as well as strength and direction of drivers on fish growth, movement, reproduction and survival in the wild. We hope to provide a comprehensive understanding of fish

The Ecology Section at the USGS Conte Laboratory has conducted individual tagging studies in a number of locations. We provide data here for three smaller studies (Sawmill river in MA, USA, Shorey brook in ME, USA, and Catamaran brook in NB, CA). The goal is to understand the strength and direction of drivers on fish growth, movement and survival in the wild. We hope to provide a...

Efforts to quantify and explain individual size distributions (ISD) are prominent in ecological research and potentially for applications to management which increasingly consider ecosystem-scale objectives. We use a nation-wide database of individual size measurements for United States stream fishes paired with species’ traits and test for direct and indirect effects of traits, flow...

This dataset consists of estimates of population trends for 236 species and species complexes of North American birds, and bird taxonomic, primary habitat biome, or conservation status group relative abundance trajectories. Both sets of estimates cover the period 1970 - 2022. Sources of data include the North American Breeding Bird Survey (BBS), Christmas Bird Count (CBC), Waterfowl...

Scripts and data that make up the habitat suitability analysis used in the Rio Grande Chub and Sucker Species Status Assessment (SSA). The scripts fall into two categories (as reflected in the src subdirectories): 1. Data processing to create Maxent inputs 2. Analysis and visualization of Maxent outputs Datasets include: 1. Data used to create habitat suitability predictors, in the...

We sampled seawater from nine mesophotic reef sites in the Pinnacles Trend and DeSoto Rim areas in the northern Gulf of America in October 2022 to complement and inform restoration investments for coral communities. Four primer sets were used to amplify environmental DNA (eDNA) from seawater, targeting metazoans, eukaryotic plankton and protists, corals, and fishes. Across all markers...

Captive wild ducks in the research colony at the USGS Eastern Ecological Science Center, Laurel, Maryland USA frequently contract Candida infections on the upper and lower bills. Various standard treatments were attempted with mixed success. Several of the Surf Scoters, especially, suffered extreme erosions of the bill leading to euthanasia prior to using this new treatment. For the past...

This data product consists of a database of population change and abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented for 546 species of birds in 4 spreadsheets containing trend estimates and annual indices for 2 time periods. Estimates are derived for each species using the 1 of 4 alternative models, and a cross
