Occurrence locations and trait data for freshwater fishes, amphibians, and reptiles native to the state of Oregon

These datasets include occurrence points and trait data for freshwater fishes, amphibians, and reptiles native to Oregon State. Occurrence data were extracted from the VertNet database and include points within Oregon, Washington, and Idaho, as well as points found within ecoregions that overlap with Oregon state (U.S. EPA Level III EcoRegions). Occurrence points include records fro

Habitat use, diet, movement, and vegetation use by western gray squirrels (Sciurus griseus) in the North Cascades Range, USA, 2008-2011

Data are contained in a comma-separated spreadsheet files (.csv) that describe vegetation characteristics of high- and low-use areas, nest tree sites, and individual nest trees used by western gray squirrels in the North Cascades as determined through live-trapping and radiotelemetry at two study sites: Stehekin, and the southern Methow Valley (Squaw Creek drainage), Washington.

Oregon Spotted Frog (Rana pretiosa) Monitoring at Jack Creek 2015-2017

This dataset contains information from mark-recapture and egg mass surveys conducted 2015-2017 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort at Jack Creek, Klamath County, Oregon. Data consist of spotted frog counts (handled by surveyors) aggregated by date, location, life stage, and sex, as well as data on environmental conditions at the

Columbia Spotted Frog (Rana luteiventris) Breeding at Grazing Exclosures in Eastern Oregon 2002-2010 and 2013

We studied the short-term effects of full and partial livestock grazing exclosures on Columbia Spotted Frog (CSF; Rana luteiventris) populations using a controlled manipulative field experiment with pre- and post-treatment data. This dataset includes vegetation data collected 2002-2010 and 2013 at 94 lakes and ponds in and around the Blue Mountains in eastern Oregon. Data collection followe...

Western US 30m Raw Heatload Values

Heat load, a unitless value from approximately 0 (low incident radiation) to around 1 (high incident radiation), is calculated using aspect, slope, and latitude (McCune and Dylan 2002 ).

Forest management and cervid herbivory data from Western Oregon, USA, 2012

Land management practices often directly alter vegetation structure and composition, but the degree to which ecological processes such as herbivory interact with management to influence biodiversity is less well understood. We hypothesized that intensive forest management and large herbivores have compounding effects on early-seral plant communities and plantation establishment (i.e., tree

Insect and vegetation community composition and abundance after wildfire and restoration seeding treatments in southwestern Idaho, USA

We conducted the first investigation of insect community responses to post-fire seeding on public rangelands by comparing the composition of insect communities at burned-and-seeded (treatment) and burned-and-unseeded (control) sagebrush-steppe ecological sites in southwestern Idaho. Insect communities in burned areas were compared to unburned (reference) areas. We collected insect an

Riparian Final Vegclass. Olympic National Park NRCA Westside Rivers Riparian Vegetation Project (2016)

Beschta and Ripple (2012) assert that increased elk populations in the Olympic National Park due to extirpation of wolves in the 1920’s has led to a reduction in riparian vegetation. They hypothesize that a decrease in this vegetation has led to an increase in erosion and undercutting of large conifer trees along the river banks, causing woody debris in the river, which in turn im

Pacific Northwest Avian Scavenger Lead and Mercury Dataset, 2012-2016

The dataset includes the bird species, region where sampled, sampling site, capture location, mercury concentration in whole blood, lead concentration in whole blood, sulfur stable isotope concentration in blood plasma, carbon isotope concentration in blood plasma, whole blood ALAD activity, and fecal corticosterone concentrations.
