Thesis:

Sympatric carnivores and vegetation structure influence the distribution and abundance of Humboldt martens in Northern California

Erika isbroadly interested in gaining insight on the ecological processes that contribute to the current distribution of Humboldt marten in Northern California. Specifically, she would like to compare space use, time of activity, and diet between marten, fisher, and bobcat to gain insight on the interspecific interactions that may influence marten populations.

Response of headwater amphibians to long-term logging impacts and assessing potential for restoration in Redwood National and State Parks

Alyssa is studying the long-term impacts of logging on headwater amphibian populations, specifically occupancy. Her research takes place in two adjacent watersheds in the Redwood National and State Parks in Northern California. One watershed is highly degraded from historic logging practices and the other is a pristine late-seral watershed untouched by logging. Her field work, in combination with various other student and park employee-run studies, will form the baseline for a restoration project aimed at restoring the logged watershed.

Thesis:

Recreation, vegetation management, and disease impact sympatric carnivore activity in California's East Bay parks

Leigh used camera traps to survey urban parkland in California’s East Bay Area for mammalian carnivore presence to investigate the potentially additive effects of development, non-consumptive recreation, and invasive vegetation management on spatiotemporal dimensions of carnivore habitat use, apparent disease prevalence, and intraguild competition.

Thesis:

Identifying habitat suitability and connectivity for Roosevelt elk (Cervus canadensis roosevelti) on the North Coast of California

Ashleywill be assessing the movement and habitat use of Roosevelt elk in Humboldt and Del Norte counties, specifically looking at the effects of land use and forest management techniques on the connectivity of elk habitat. She will also be using remote game cameras to assess the density of elk across different land use types. Assessing the density and movement of elk will help inform effective land management decisions for increasing suitable elk habitat, and in turn, decrease the amount of human-wildlife conflict areas.

Carnivore and ungulate response to livestock in a grazed forest ecosystem

Using data collected from remote camera traps in grazed and ungrazed areas of the Warner Mountains in northeastern California I will determine if wildlife shift the specific times of day they are active and/or change their habitat use in response to grazing cattle. Livestock grazing is one of the most widespread influences on native ecosystems and has varied impacts on wildlife. Myhope isthat land managers can use the information gathered on wildlife behavior to improve grazing strategies, facilitate coexistence with wildlife, and allow for the continued multiple uses of the Modoc National Forest with wildlife conservation in mind.
