Summer is interested in mammalian conservation and has experience trapping and studying small mammal populations in California, Washington, and Colorado. Before coming to UC Davis she worked several field seasons for the US Forest Service mammal trapping as part of demography studies.
Her Master’s project will utilize a long-term data set collected on a population of golden-mantled ground squirrels (Callospermophilus lateralis) at the Rocky Mountain Biological Laboratory in Gothic, Colorado. She is particularly interested in body mass dynamics and effects variables such as climate have on survival.

Amy studies the efficacy of conservation strategies aimed at mitigating habitat fragmentation. Currently she is studying the effectiveness of wildlife crossing structures in California, US, and community based resource management in Pemba, Tanzania.

Aviva studies habitat use by species, and how that can be used to predict changes to range under climate change. Her current work focuses on montane ground squirrels in the Sierra-Nevada. Warming temperatures and changing precipitation patterns in the Sierra Nevada will lead to changes the distribution of habitat these species depend on. This changing habitat and environmental conditions will likely result in species occurring in different location in the future than where they are now. Being able to predict where those new locations will be is important for conservation and management decisions. Initial work is to quantify habitat use by three common montane ground squirrels: Yellow-bellied Marmots (Marmota flaviventris), Belding’s Ground Squirrel (Urocitellus beldingi), and Golden-Mantled Ground Squirrels (Callospermophilus lateralis).
