DNA yields and concentrations from buccal swab samples of Red-Cockaded Woodpeckers

The data were generated as part of a study to determine if buccal (oral) swabs could be used to obtain genetic material from Red-Cockaded Woodpecker chicks. Different swab types were investigated to determine if any specific type gave the highest DNA yields.

Western US 30m Heatload Values

Heat load, a unitless value from 0 (low incident radiation) to around 1 (high incident radiation), is calculated using aspect, slope, and latitude (McCune and Dylan 2002 ). For the purposes of the exploration tool, the data are binned into 6 classes using Geometric Interval. Classes range from very low to very high and are designed to allow the classification of a polygon into its heat load...

Oregon Spotted Frog (Rana pretiosa) Monitoring at Jack Creek 2015-2018

This dataset contains information from mark-recapture and egg mass surveys conducted 2015-2018 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 time each survey...

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...

Streamflow Observation Points in the Pacific Northwest, 1977-2016

This dataset includes spatial locations in the Pacific Northwest where streamflow observations were recorded. For the purpose of this investigation, all streamflow observations were converted into wet or dry indicator values.

Mercury Exposure in Piscivorous Birds at the Carson River (NV) Superfund Site, 1997-2006

These data support studies from 1997-2006 on potential toxicity of mercury concentrations within the lower Carson River system to piscivorous birds - snowy egrets, black-crowned night-herons, and double-crested cormorants.

Created snag characteristics and cavity-nesting bird associations in the CFIRP stands, McDonald-Dunn Research Forest, Corvallis, OR, USA, 2016

We measured characteristics of 731 snags and quantified foraging and breeding use of snags by birds 25-27 years after their creation, and examined whether different harvest treatments (i.e., group selection, two-story, clearcut) and snag configurations (i.e., scattered and clustered) influenced snag characteristics or avian use for foraging and nesting.
