Data from a road ecology study of Spotted Salamanders along the Natchez Trace Parkway, Mississippi, in 2012-2013 Data from a road ecology study of Spotted Salamanders along the Natchez Trace Parkway, Mississippi, in 2012-2013
This dataset contains study results examining the effect of road mortality on migrating salamanders along the Natchez Trace Parkway in Mississippi from 2012-2013. A combination of methods were used to assess the movement of salamanders to and from the breeding pond. Environmental variables such as air and water temperature, water salinity, and relative humidity were also collected during...
Data from time-constrained visual encounter surveys and acoustic surveys for amphibians and reptiles in the Atchafalaya Basin conducted from 2008 through 2016 Data from time-constrained visual encounter surveys and acoustic surveys for amphibians and reptiles in the Atchafalaya Basin conducted from 2008 through 2016
This dataset contains data from time-constrained visual encounter surveys conducted in the Atchafalaya River Basin in South Central Louisiana from February 2008 through July 2016. In addition, it contains vocalization data collected concurrently with the visual encounter surveys and data on presence of tadpoles and larvae. All participants in surveys are included in the dataset...
Summarized model outputs for a predator-prey-competitor model for Macrhybopsis and Scaphirhynchus in the Lower Missouri River Summarized model outputs for a predator-prey-competitor model for Macrhybopsis and Scaphirhynchus in the Lower Missouri River
Data represents summarized model outputs for various simulation scenarios performed used the Fish community bioenergetics model published at: https://doi.org/10.5066/P1XAZ6K9. A number of scenarios were explored to address specific queries regarding sturgeon-chub-invertebrate dynamics in the lower Missouri River. Data include a simulated pallid sturgeon maximum weight over time under...
Orthomosaic maps of the Clackamas River, Oregon, produced from images acquired April 16-18, 2024 Orthomosaic maps of the Clackamas River, Oregon, produced from images acquired April 16-18, 2024
A Cessna 182 fixed-wing aircraft equipped with a multispectral camera was used to collect aerial imagery of selected river reaches within the Willamette River Integrated Water Science basin in Oregon. On April 16-18, 2024, image acquisition was focused on four reaches of the Clackamas River. Photogrammetry techniques were applied to the images consisting of visible or red, green, and...
Dataset for Antigone canadensis (sandhill crane) foraging patterns influenced by crop, roost distance, and tillage intensity during spring and autumn migration at a primary stopover area Dataset for Antigone canadensis (sandhill crane) foraging patterns influenced by crop, roost distance, and tillage intensity during spring and autumn migration at a primary stopover area
We used data from 2.5 years of A. canadensis observations in the San Luis Valley to examine their foraging patterns during spring and autumn migration. We counted cranes weekly or bi-weekly each season and year during roadside surveys. We determined crop type (alfalfa, barley, pasture, potatoes, other grain, and other) during roadside surveys. We also recorded tillage intensity for grain...
Model archive summary and suspended-sediment concentrations from a surrogate ordinary least square regression analysis for station 05517500, Kankakee River at Dunns Bridge, Indiana, April 2016 through July 2020 Model archive summary and suspended-sediment concentrations from a surrogate ordinary least square regression analysis for station 05517500, Kankakee River at Dunns Bridge, Indiana, April 2016 through July 2020
Sediment accumulation and transport negatively affect flood control, water supply, aquatic life, reclamation, and recreation (Angino and O’Brien, 1968) and are concerns of resource managers in the Kankakee River Basin of northern Indiana and throughout many regions of the United States. By relating continuously monitored water-quality data to discrete data collected from April 2016...
