Targeting Social Cohesion In Female Roosevelt Elk (Cervus Canadensis Roosevelti) Groups Minimizes Survey Efforts For Fecal Dna Capture-Recapture Estimates Of Abundance, Rudolph Gabriel Mena

Theses and projects

Group size abundance estimates of Roosevelt elk (Cervus canadensis roosevelti) in Humboldt and Del Norte counties, California have largely been inferred through visual counts. However immigration and emigration, the inability to sight elk behind viewing obstructions, and a lack of individual identifiers makes precise and accurate estimates difficult to obtain. Using DNA collected through fecal samples left by elk groups can aid in addressing these difficulties. I tested the hypothesis that GPS (Global Positioning System) collar data from adult female elk could indicate discrete site use locations of their social groups, which in turn yield sufficient sample sizes for use ...
