We partitioned a Mahalanobis D2 model of sage-grouse habitat use into separate additive components each representing independent combinations of species-habitat relationships to identify and map range-wide ecological minimums for sage-grouse. We assumed the states delineations of priority areas capture higher quality habitat and larger numbers of sage-grouse populations across our study area. We randomly selected 1669 points from the priority areas and corresponding variables GIS datasets to calibrate models. We estimated distributions of our variables from 1000 iterative samples created by bootstrapping the calibration data. To better incorporate conditions in both large and small priority areas, we restricted...

These data have been collected on various vessel operations on the Great Lakes and select connecting waterways. This vessel operations data set is part of and connected to a larger database of Great Lakes research that includes trawl and gillnet catch data, sample information of fish species caught, as well as effort applied, operation conditions, and location details. The larger database also contains data on hydroacoustics, ichthyoplankton, zooplankton, zebra mussel, and benthos samples collected. Multiple operations were conducted on all Great Lakes each year (1958-2016) beginning in early spring and ending in late fall. Each vessel operation was completed for a specific purpose, or target mission, which are...

This Data Release provides records of fish species abundance collected during summer 2015 using single pass backpack electrofishing within sections of Owens Creek, Big Hunting Creek, and Blue Blazes Creek (a tributary to Big Hunting Creek) in Maryland (USA). We also provide water and air temperature data collected during at 30 minute increments summers of 2015 and 2016. Stream physical habitat data are also reported for fish sampling sites.
