Oregon State University Faculty Research Assistant in Corvallis, Oregon
Internal Job Number: P02595UF
The Institute of Natural Resources invites applications for a full-time (1.00 FTE), 12-month, Faculty Research Assistant position. Reappointment is at the discretion of the Director.
The position will focus on understanding the effects of biotic and abiotic factors on the demography and habitat associations of the fisher (Pekania pennanti) in the southern Sierra Nevada. Primary factors of interest include forest management activities such as thinning and prescribed fire, tree mortality related to bark-beetles, and changes in climatic conditions that could influence forest habitat conditions or fisher use of the landscape. The incumbent primarily serves as a geospatial analyst providing geographical analysis and data processing to various projects primarily associated with fisher research. Primary duties are in GIS, spatial modeling, remote sensing, and data processing support. Principle foci include (1) extracting environmental variables from existing raster map layers, in order to relate species (e.g., fisher) locations to the amount and configuration of surrounding habitat elements and topographic elements at multiple scales; (2) deriving landscape metrics from raster layers; (3) processing and analysis of animal movement data; (4) applying remote sensing techniques to map land cover types (e.g. tree mortality) in the study area using satellite imagery. Of note, although some field work is ongoing, most of the data to be used in analysis have already been collected as part of two long term studies of fisher ecology in the southern Sierra Nevada. The incumbent will thus be contributing to final analyses and products that stem from a decade of field work on a species of high regional conservation value, and will be supporting collaborations with other professionals working to address various questions related to fisher ecology in a changing forest environment.
