We developed an age-structured population matrix model to perform population viability analysis for Lower Missouri River (LMR) shovelnose sturgeon (Scaphirhynchus platorynchus). We investigated potential effects of the commercial fishing moratorium put in place to help protect the similar-appearing pallid sturgeon (S. albus). The model applies different components of total variance in life history parameters at different levels: sampling variance (parameter uncertainty) between model iterations; temporal variance (temporal environmental fluctuations) between time steps within iterations; and individual variance (individual differences) within each time-step. The model predicted annual rates of population increase...

This data set contains information on detections of amphibians at four bottomland hardwood restoration sites in northeastern Indiana in 2015 and 2016. Amphibian communities were surveyed using four different methods—automated recording units, diurnal visual encounter surveys along transects, nocturnal transect surveys, and amphibian rapid assessments. The data set contains three tables: 1) site descriptions and bounding coordinates, 2) detections of vocalizing anurans (i.e., frogs and toads) recorded by automated recording units, and 3) detections of amphibians by diurnal visual encounter surveys, nocturnal transect surveys, and amphibian rapid assessments.
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
