Using Environmental Dna And Occupancy Modeling To Estimate Rangewide Metapopulation Dynamics Of The Endangered Tidewater Goby Eucyclogobius Spp., Chad M. Martel
Cal Poly Humboldt theses and projects
Conservation of species is most effective when metapopulation dynamics are well understood and incorporated into management plans, allowing managers to target conservation efforts where they will be most effective. The development of environmental DNA (eDNA) methods provides an efficient and highly sensitive approach to generate presence and absence data needed to elucidate metapopulation dynamics. Combining sample detection histories from eDNA surveys with occupancy models that account for non-detection can offer unbiased estimates of rangewide metapopulation dynamics. However, traditional occupancy models do not allow direct evaluation of the drivers of site occupancy, extinction, and colonization. Herein, I utilize a novel dynamic …
Elucidating Patterns Of Bat Species Occupancy Across A Disturbed Landscape In California's Central Valley, Trinity N. Smith
Elucidating Patterns Of Bat Species Occupancy Across A Disturbed Landscape In California's Central Valley, Trinity N. Smith
Cal Poly Humboldt theses and projects
California’s Central Valley, one of the most productive agricultural regions in the world, is home to 14 species of resident and migratory bats. The Central Valley has been identified as a crisis ecoregion, and a high number of species are at risk due to anthropogenic land use. In addition, the Central Valley has faced severe drought, effects of which are intensified on the natural landscape by agricultural irrigation practices. In response to the historical drought of 2012-2015, California Department of Fish and Wildlife (CDFW) implemented the Terrestrial Species Stressor Monitoring (TSSM) project, which in part aimed to collect information on …
