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...

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...

Brown trout movement data in Glen and Grand Canyons, Arizona, USA Brown trout movement data in Glen and Grand Canyons, Arizona, USA

These data were compiled to test hypotheses regarding drivers of movement of brown trout. Objectives of our study were to test whether the degree of movement varied in response to placement of a weir in Bright Angel Creek, fall timed flooding events, or simply seasonal changes. These data represent summarized capture histories of brown trout in terms of states based on physical locations...

Bumblebee Surveys in Montana, North Dakota, South Dakota, and Nevada, USA (ver. 3.0, March 2025) Bumblebee Surveys in Montana, North Dakota, South Dakota, and Nevada, USA (ver. 3.0, March 2025)

Bumblebee community surveys used occupancy survey designs primarily across lands managed by the Bureau of Land Management (BLM) and Glacier National Park (GNP). They also include a few surveys in Nevada. These records represent timed surveys that were both successful and unsuccessful in detecting bumble bees.

Burn probability models calibrated using past human and lightning ignition patterns in the Madrean Sky Islands, Arizona Burn probability models calibrated using past human and lightning ignition patterns in the Madrean Sky Islands, Arizona

Burn probability (BP) models involve the simulation of multiple individual wildfires across a landscape to obtain estimates of fire likelihood at any given location based on ignition source, local terrain, fuels and weather. We used FlamMap software to generate BP for 10,000 simulated fires under the three ignition scenarios: human ignition scenario (HIS), lightning ignition scenario...

Burn probability predictions for the state of California, USA using an optimal set of spatio-temporal features. Burn probability predictions for the state of California, USA using an optimal set of spatio-temporal features.

Burn probability (BP) models the likelihood that a location could burn. However, predicting BP is extremely challenging, because fire behavior varies strongly among landscapes and with changing weather conditions and wildfire spread simulations are computationally intensive and require integration of data with large spatial and temporal variability. In this data release we include the...

Burn Severity Portal, a clearing house of fire severity and extent information (ver. 11.0, April 2025) Burn Severity Portal, a clearing house of fire severity and extent information (ver. 11.0, April 2025)

The various post-fire data products available on the Burn Severity Portal are produced using satellite imagery. The timing of the satellite imagery used, relative to the fire event, typically depends on the vegetation type and structure where the fire occurred. Each mapping program produces a suite of data products based on user intended user needs. You can find additional details in...

Calibrated marine sparker source amplitude decay versus offset offshore Santa Cruz, California Calibrated marine sparker source amplitude decay versus offset offshore Santa Cruz, California

This two-vessel survey was designed to quantify the decay of sound emitted from the SIG ELP790 minisparker (powered at 700 joules) and from the Applied Acoustics Delta Sparker (powered at 1.0 and 2.4 kilojoules) as a function of distance during marine geophysical surveys. Seven transect sites were surveyed at five different water depths (25, 50, 100, 200, and 600 meters) to compare the...

Caloosahatchee River Nutrient Enrichment Mesocosms: Phytoplankton Taxonomic Quantification September 2019, June 2020, September 2020, February 2021 Caloosahatchee River Nutrient Enrichment Mesocosms: Phytoplankton Taxonomic Quantification September 2019, June 2020, September 2020, February 2021

An interdisciplinary and multiagency study was undertaken to study harmful algal bloom (HAB) dynamics on the Caloosahatchee River, which drains to the west from Lake Okeechobee into the Gulf of Mexico. Algae and cyanobacteria play crucial roles in aquatic ecosystems, but under favorable environmental conditions certain taxa may experience population growth booms resulting in HABs. Four...

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...

Cameron-Creole Maintenance (CS-04a): 2018 land-water classification Cameron-Creole Maintenance (CS-04a): 2018 land-water classification

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) 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...

Caminada Headland restoration area – 2018 habitat map, Louisiana Barrier Island Comprehensive Monitoring Program Caminada Headland restoration area – 2018 habitat map, Louisiana Barrier Island Comprehensive Monitoring Program

This package includes a detailed habitat map, general habitat map, and georeferenced imagery from 2018 for the National Fish and Wildlife Foundation (NFWF) Caminada Headland Beach and Dune Restoration Incr2 project area (BA-0143). The project restored 489 acres of beach and dune habitat along more than seven miles of Caminada Headland in Jefferson and Lafourche Parishes through the...
