Data
Our interdisciplinary, integrated science teams develop various data sets in support of the USGS mission areas. This information then aids natural resource managers in decision making and support of the complex issues they face in today's world. The data and tools listed here are official USGS data releases.

Data related to great diversity of KSalpha genes from bat skin external microbiota, from Arizona and New Mexico, indicate novel PKSII biosynthetic gene clusters Data related to great diversity of KSalpha genes from bat skin external microbiota, from Arizona and New Mexico, indicate novel PKSII biosynthetic gene clusters
We documented the type two polyketide synthases(PKS II) gene diversity and novelty by sequencing KSalpha; genes known to synthesize bioactive small molecules. Sequences were derived from culturable bacteria isolated from bats in Arizona and New Mexico. We targeted the PKS II pathway which comprised a large proportion of the culture collection. Genomic analyses of a 16-member subset of...
USGS BiblioSearch: A python tool to facilitate searching, cleaning, and compiling of literature search results from across multiple citation databases USGS BiblioSearch: A python tool to facilitate searching, cleaning, and compiling of literature search results from across multiple citation databases
USGS BiblioSearch is a python tool that performs literature searches across multiple citation databases via APIs or other web services in Python. The tool provides a quick method to query keywords and clean and compile results. Currently, the software includes methods to search four databases - Clarivate Web of Science, Elsevier Scopus, USGS Publications Warehouse, and USGS ScienceBase.
Vascular plant diversity and associated environmental variables along the Elwha River, Washington, 2005-2017 Vascular plant diversity and associated environmental variables along the Elwha River, Washington, 2005-2017
The data release presents observations of riparian vegetation, topography, soil characteristics, and ground cover in three river segments located above, below, and between the former Glines Canyon and Elwha Dams on the Elwha River, near Port Angeles, WA (river kilometers 2.5 to 31) to assess effects of dam removal on riparian vegetation. Vegetation data were collected before dam removal...
Gunnison sage-grouse habitat suitability of six satellite populations in southwestern Colorado: San Miguel, Crawford, Pinon Mesa, Dove Creek, Cerro Summit-Cimarron-Sims, and Poncha Pass Gunnison sage-grouse habitat suitability of six satellite populations in southwestern Colorado: San Miguel, Crawford, Pinon Mesa, Dove Creek, Cerro Summit-Cimarron-Sims, and Poncha Pass
We developed habitat selection models for Gunnison sage-grouse (Centrocercus minimus), a threatened species under the U.S. Endangered Species Act. We followed a management-centric modeling approach that sought to balance the need to evaluate the consistency of key habitat conditions and improvement actions across multiple, distinct populations, while allowing context-specific...
Brown treesnake capture and morphometric data using live mouse- and bird-lure traps on Guam, 2013 Brown treesnake capture and morphometric data using live mouse- and bird-lure traps on Guam, 2013
We deployed 30 trap stations consisting of three combinations: isolated bird-lure traps, isolated mouse-lure traps, or paired stations to evaluate snake capture as a function of lure. At the paired stations, we included two traps: one bird-lure trap and one mouse-lure trap. All stations were at least 60 meters (m) apart and each of the station treatments was replicated 10 times. Traps at...
Camera trap data of Brown Treesnakes at mouse-lure traps on Guam, 2015 Camera trap data of Brown Treesnakes at mouse-lure traps on Guam, 2015
Manually photo-processed remote camera trap data of Brown Treesnakes on Guam at snake traps with live mouse lures. Records of snakes entering the field of view (FOV) and exiting the FOV by day, time, and trap location. Photos were further processed to retain only detections of snakes up to 1.83 meters from the camera, i.e., only records of snakes that were on or in front of the mouse...
Brown Treesnake morphological and behavioral differences following ingestion of large meals, 2015 Brown Treesnake morphological and behavioral differences following ingestion of large meals, 2015
Data set resulting from monitoring the behavior of snakes (n = 62) that had been feed a standardized large meal with transmitter, proportional to their body mass, to make direct comparisons to a control group of snakes that had not been fed a meal (only the transmitter). Transmitters were equipped with a two-position switch that changes pulse rate when the body position of the animal...
Surveillance and reports of Brown Treesnakes on Saipan, 1980-2020 Surveillance and reports of Brown Treesnakes on Saipan, 1980-2020
Available active surveillance efforts for Brown Treesnakes on the island of Saipan via nocturnal visual encounter surveys and trapping from 1999-2018 were collected and summarized into 3 csv files (TRAP1999, BTSRRTSaipanTRAP, and BTSRRTSaipanVISUAL). Location and date of non-confirmed reports of snakes 1982-2013 via passive surveillance were compiled into a fourth file (Saipan...
Brown Treesnake trap captures, Guam National Wildlife Refuge, 2014 Brown Treesnake trap captures, Guam National Wildlife Refuge, 2014
Over a 22-week period both with and without active Brown Treesnake (BTS) snake removal, we evaluated snake-trap contact rates at mouse- and bird-lure traps within the Guam National Wildlife Refuge in 2014. Bird-lure traps served as a proxy for reintroduced nesting birds. Data consists of 3 files generated from camera surveillance and trapping using mouse and bird lures in conventional...
Offspring, dam, sire pedigree assignments in a managed population of Brown Treesnakes on Guam Offspring, dam, sire pedigree assignments in a managed population of Brown Treesnakes on Guam
In this dataset offspring are assigned to a dam and sire using information from single nucleotide polymorphisms (SNPs) from previously published pedigree reassignments of Brown Treesnakes within the U.S. Geological Survey's Brown Treesnake study enclosure on Northwest Field of Andersen Air Force Base, Guam (Levine and Yackel Adams 2021 and Nafus 2021) to update the overall pedigree...
Brown Treesnake detections on transects using potential attractants of live-mouse lures or fish-spray scent, Guam Brown Treesnake detections on transects using potential attractants of live-mouse lures or fish-spray scent, Guam
Nocturnal visual encounter surveys for Brown Treesnakes were collected and summarized into 4 plain text files (csv format): CapturesLure, SurveysLure, CapturesScent, and SurveysScent. Capture files contain unique Passive Integrated Transponder (PIT) tag identification and measurements of snakes with dates and locations of capture. Survey files contain the dates of transect sampling and...
North American tree-ring fire-scar site descriptions North American tree-ring fire-scar site descriptions
Fire size and severity continue to increase across large parts of North America, driven by a combination of climate change and effects of human land use. Instrumental records are too short to fully understand patterns, trends, and drivers of fire that are necessary to model future fire. Tree-ring fire scars provide centuries-long records of fire regimes, including fire frequency, season...
