Data and Tools

Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Oregon Spotted Frog (Rana pretiosa) Monitoring at Jack Creek 2015-2016

This dataset contains information from mark-recapture and egg mass surveys conducted 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 aggregated by date, location, life stage, and sex, as well as data on environmental conditions at the time each survey.

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.

Velocity profiling at the US Army Corps of Engineers Electric Dispersal Barrier in the Chicago Sanitary and Ship Canal during passage of fully loaded commercial tows

In 2016, the U.S. Fish and Wildlife Service, U.S. Geological Survey, and U.S. Army Corps of Engineers undertook a large-scale interagency field study to determine the influence of commercial barge vessels on the efficacy of the Electric Dispersal Barrier System (EDBS) in the Chicago Sanitary and Ship Canal (CSSC) in preventing fish passage.

Asian carp acoustic stimuli data

Broadband sound recorded from an outboard motor can modulate carp behavior in captivity; however, the response of wild silver carp to broadband sound has yet to be determined. This data set includes information regarding the sound produced by outboard motor and speakers in the field and will help in determining effectiveness of the usage of control techniques in the management of carps.

Using a gradient in food quality to infer drivers of fatty acid content in two filter-feeding aquatic consumers:Data

Inferences about ecological structure and function are often made using elemental or macromolecular tracers of food web structure. For example, inferences about food chain length are often made using stable isotope ratios of top predators and consumer food sources are often inferred from both stable isotopes and fatty acid (FA) content in consumer tissues.

Using a gradient in food quality to infer drivers of fatty acid content in two filter-feeding aquatic consumers:Data

The use of FAs as tracers implies some degree of macromolecular conservation across trophic interactions, but many FAs are critically important for particular physiological functions and animals may selectively retain or extract these critical FAs from food resources. Here, we compared spatial variation in two taxa that feed on the same (or similar) food resources.

Experimental observations on the decay of environmental DNA from bighead and silver carp-Data

Environmental DNA (eDNA) decay rates in waste materials and reproductive cells obtained from captive stocks of the invasive bigheaded carps, as well as the influence of differing levels of water turbulence, temperature, microbial load, and pH on rates of eDNA decay. 

Our results strongly demonstrate the potential for environmental factors to influence eDNA fate, and thus the...
