Invertebrate community data from native trout lakes and streams in the Southern Rocky Mountains Invertebrate community data from native trout lakes and streams in the Southern Rocky Mountains

Native trout in the West suffer a high degree of vulnerability, as highlighted by cutthroat trout, a group of 14 subspecies, most of which have been petitioned for listing under the Endangered Species Act (ESA). In the Southern Rocky Mountains, greenback cutthroat trout (Oncorhynchus clarkii stomias; GBCT) are listed as threatened under the ESA, and few populations remain, in part...

Dataset from 2015-2016 thermal and behavior monitoring of Argentine giant tegus in Everglades, Florida Dataset from 2015-2016 thermal and behavior monitoring of Argentine giant tegus in Everglades, Florida

Thermal data collected from iButton temperature loggers implanted into research animals (Argentine giant tegus) and in their surrounding environment. Tegus undergo winter dormancy (hibernation) to cope with colder temperatures, and we studied the thermal habits of wild tegus within their invaded range in southern Florida, USA. We used radiotelemetry and trail cameras to verify dates of...

Bird Behavior and Mortality in Relation to Power Lines in Prairie Habitats, North Dakota, 1981to1982 Bird Behavior and Mortality in Relation to Power Lines in Prairie Habitats, North Dakota, 1981to1982

A biologist and field crew from Northern Prairie Wildlife Research Center observed bird flights at 7study sites, twice weekly during two spring and two fall migration periods between April 3, 1981 and May 20, 1982. Study sites were located in south-central North Dakota in Barnes, Kidder, and Stutsman counties. The database includes flight observation's of bird species in the vicinity of...

Potential productivity and change estimates for eight grassland species to evaluate vulnerability to climate change in the southern Great Plains Potential productivity and change estimates for eight grassland species to evaluate vulnerability to climate change in the southern Great Plains

This data set includes the relative production scenarios for eight (8) grass species based on linear models from Epstein, et al. (1998). We selected two indicator species for each community: shortgrass prairie: blue grama (Bouteloua gracilis; BOGR) and buffalo grass (Bouteloua dactyloides; BODA); mixedgrass prairie: sideoats grama (Bouteloua curtipendula; BOCU) and little bluestem...
