Viorel Popescu – Conservation Ecology Lab


Conservation Ecology Lab; quantitative wildlife ecology and conservation science

Welcome to the Conservation Ecology Lab in the Department of Biological Sciences at Ohio University. We work on applied wildlife and conservation research across many systems: from Ohio’s deciduous forests, to mountains of the Pacific Northwest and California, the Romanian Carpathians, and subtropical China. Our research interests are diverse, spanning large carnivores, reptiles and amphibians, and we use experimental, observational and computational approaches to tackle current conservation issues. We work on a variety of issues, for example sustainability of carnivore trophy hunting, impacts of roads on wildlife populations, carnivore population ecology, systematic conservation planning, and impacts of climate change on amphibian populations.

LATEST NEWS!!!  (also check out the NEWS page for updates)
  • We received funding from the Ohio Department of Natural Resources to study bobcat ecology in Ohio! Looking forward to working with Ohio Division of Wildlife biologists over the next 4 years to develop a population model to understand the viability of Ohio’s recovering bobcat population, and inform bobcat management and conservation. Graduate student Heidi Bencin started preliminary work on occupancy and non-invasive genetics this Summer (2017). Looking for a PhD student to continue her work (check out ad here ECOLOG).


  • New paper on estimating brown bear abundance in the Romanian Carpathians using snow and mud track surveys is out in Ecology and Evolution! With colleagues from Vrancea EPA ( and Association for Biodiversity Conservation (, we tested the traditional method for monitoring brown bears using track surveys employed by the Romanian game managers by implementing a robust design (multiple visits on the same transect), using hierarchical statistical methods,  and integrating home range data. Well, even with all these twists, simply replying tracks did not fare well for estimating abundance, highlighting the need for a paradigm shift in Romanian large carnivore management, and for DNA-based surveys.
HUGE CONGRATS to all my lab members; they rocked the grant and job world! After spending a semester writing grants and research proposals, March 2017 proved to be the best month of my year at Ohio University… when it rains, it pours:
  • Cassie Thompson (MSc) won a prestigious NSF Graduate Research Fellowship for her research on amphibians and climate change
  • Heidi Bencin (MSc) was awarded an OCEES (Ohio Center for Ecology and Evolutionary Studies) Fellowship, which provides stipend and teaching relief for Fall 2017; she was also awarded a $6K Student Enhancement Award (a competitive Ohio University research grant) for her work on bobcat ecology and management
  • Marcel Weigand (MSc) was awarded a $6K Student Enhancement Award as well for her work on turtle ecology and roadways



Prospective graduate students: If you are interested in being part of my lab at Ohio University, please send me: (A) a short statement about yourself and your research interests (background, goals/ambitions, why Ohio University), (B) your resume or CV, and (C) your GPA and GRE scores.

The main research directions in the lab are: (1) amphibian ecology and conservation, (2) carnivore ecology and conservation, and (3) spatial conservation planning, but incoming students may to develop their own projects focused on other conservation topics of interests.
