DSC_0014I recently defended my PhD and I am continuing on for the the summer as a postdoc with Wendy at Simon Fraser University in Burnaby, British Columbia. I am part of the Earth to Ocean research group, and I’m interested in how we can use life-history data to both forecast declines and the potential for recovery within a population or a species.  I’m taking a demographic modeling approach to elucidate specific points within the life-cycle of a population that are particularly vulnerable to decline, or on the flip side, can be targeted for improvement through conservation measures. My work covers a wide spectrum of current conservation issues, from how to recover a population on the brink of extirpation, to how climate change will affect currently stable populations of montane amphibians. The common thread that ties my research together is providing a strong, quantitative framework for decision-making (present and future) that is grounded in the biology of a species.

Since 2010, I have worked with the B.C. Oregon spotted frog recovery team to evaluate the tradeoffs between various recovery strategies for this highly imperiled species.  Specifically, I have focused on the potential of two common population supplementation strategies, head-starting and captive breeding, to reduce the extinction probability of a declining population.  Using demographic data I have collected over the past three years on Oregon spotted frogs  (Rana pretiosa) in B.C., I am developing models that include both a biological and economic component to recovery, with the ultimate goal of providing the recovery team with a suite of viable options to stem the decline of the species in Canada.

7Lakes-8496In addition to my endangered species work, in 2013 I jumped on board with Maureen Ryan and Wendy to explore the effects of climate change on montane amphibians in the Pacific Northwest.  I am working on a thread of this large, collaborative project with the goal of forecasting the response of Cascades frogs (Rana cascadae) to changes in climatic regime.  I am now collecting baseline data on landscape-level larval mortality of R. cascadae induced by pond-drying. These data will be used along with long-term demographic data to “add up” the effects of climate change on different life-history stages of this species to determine the overall response of the species across its distribution.
