Karen Beard, Professor
My field of specialization is conservation biology. My research usually focuses on species interactions and subsequent impacts on ecosystem processes, especially focused on the issues of invasive species and climate change. I am especially excited about a few projects I’m starting. I have been working with a group of graduate students at USU on the traits that make herpetofauna invasive. The results of some of this work will be part of a Special issue on Reptile Conservation in Biological Conservation. I am also in the throws a 3-year NSF-funded research project on the Yukon-Kuskokwim Delta on the effects of changes in migratory bird timing and the start of the growing season on ecosystem functioning. Finally in the past year I have started a new project on the effects of changing precipitation patterns in Utah and have new students continuing research on the impacts of an invasive frog in Hawaii.
Current Graduate Students
Ryan Choi, PhD Student
Ryan is studying the impacts of climate change on ecosystem function in the Yukon Delta National Wildlife Refuge in Alaska. He is focused on how phenology of sub-arctic tundra plants and the seasonal arrival of migratory Pacific black brant (Branta bernicla nigricans) affects ecosystem functioning at our Tutakoke River field site.
Leandro Do Nascimento, PhD Student
Leandro is studying the effects of land use change and habitat heterogeneity on biodiversity in the Amazon Basin. He is going to focus on using acoustic diversity as a proxy for biodiversity.
Lindsay Carlson, MS Student
Lindsay is also working on the Yukon Delta National Wildlife Refuge in Alaska. She is studying the effects of climate change on compeitition between two dominant plants at our Tutakoke River field site.
Martin Holdrege, MS Student
Martin is studying how changes in precipitation will influence a shrub-steppe communities and an agricultural ecosystem in Cache Valley. He is leading a large manipulative rainfall experiment in two sites and measuring plant and soil responses to these manipulations.
Robyn Smith, MS Student
For her research, Robyn studied the interactions between the avian community and coqui frogs in Hawaii. She conducted a landscape-scale survey and an isotopic diet analysis.
Shane Hill, MS student
Shane is studying predators of coqui frogs and determining how invasive coquis influence introduced mammal populations, nest predation rates and what animals scavenge and consume frogs.
Current Undergraduate Researchers
Sydney is an USU undergraduate researcher working on root biomass patterns across Kruger National Park, South Africa.
Thomas is an USU undergraduate working in the Y-K Delta, Alaska. He'll be investigating the role of different components of herbivory on CN cycling. He received an URCO and QCNR funding to support this work
