EverWaders species distribution model development and output in the Greater Everglades from 2000-2009 EverWaders species distribution model development and output in the Greater Everglades from 2000-2009
Restoration of the Florida Everglades, a substantial wetland ecosystem within the United States, is one of the largest ongoing restoration projects in the world. Decision-makers and managers within the Everglades ecosystem rely on ecological models forecasting indicator wildlife response to changes in the management of water flows within the system. One such indicator of ecosystem health...
Discharge records and sand extents along the Colorado River between Glen Canyon Dam and Phantom Ranch, Arizona Discharge records and sand extents along the Colorado River between Glen Canyon Dam and Phantom Ranch, Arizona
The data contained in these tables detail the areal extent of exposed sand, in square meters, along the Colorado River between Glen Canyon Dam, Arizona, and Bright Angel Creek, Arizona, within Glen Canyon National Recreation Area and Grand Canyon National Park. Sand exposure areas are provided as a function of Colorado River discharge, as measured at Lees Ferry, Arizona, in increments of...
Stream classification and gravel bar inventory for Buffalo National River and Ozark National Scenic Riverways, 1982-2014 Stream classification and gravel bar inventory for Buffalo National River and Ozark National Scenic Riverways, 1982-2014
This data release contains numerous shapefiles that describe baseline characterization of the physical attributes of the riverine ecosystems in two national parks - Ozark National Scenic Riverways (ONSR), Missouri, and Buffalo National River (BNR), Arkansas. The individual metadata associated with each shapefile describe in detail the specific process steps, source inputs for the data...
Modeled Stream Metabolism in Boulder Creek near Boulder, CO (2016 - 2018) Modeled Stream Metabolism in Boulder Creek near Boulder, CO (2016 - 2018)
The data presented here was collected adjacent to USGS stream gage 06730200 and includes both observed and modeled values. Dissolved oxygen, dissolved carbon dioxide, stream depth, water temperature, and light intensity were collected via passive water quality sensors. Modeled values include gross primary production, ecosystem respiration, net ecosystem production, reaeration, and light...
Brown Treesnake Mortality Habitat Management Unit Guam 2019 Brown Treesnake Mortality Habitat Management Unit Guam 2019
The dataset contains 16 columns of data collected on invasive Brown Treesnakes (Boiga irregularis) at a study site known as the Habitat Management Unit (HMU) in northern Guam. Snakes were fitted with radio-transmitters and teams of 2-4 biologist listened for signals from transmitters every seven days to determine if snakes were alive or dead. Survival data was then modeled in Program...
