Announcement
2024-05-16: Monitoring animal populations and communities to assess ecological integrity and inform
- date：2024-05-15

Speaker: Dr. Viorel Popescu
Affiliation: Columbia University (USA) and University of Bucharest, Romania. Prior to Columbia University
Host: Prof. Ahimsa Campos-Arceiz
Time: 4:30 PM, Thursday, May. 16, 2024
Abstract：
Monitoring animal populations and communities is a critical part of safeguarding biodiversity and ecological integrity. Many species, communities and ecosystems are data-deficient due to their status (rare species, hard to detect) or lack strong monitoring programs to assess population changes over time. I will be presenting several examples on how statistical methods that account for imperfect detection and data such as eDNA and camera trap photo can be integrated to quantify accurate and precise population and community occupancy estimates and trends, evaluate interspecific interactions and predict population trajectories in the future. Combining multiple statistical methods and types of data can be used to develop powerful monitoring protocols for tracking populations through time and identify drivers of decline (or improvement) in species and ecosystem integrity.

Dr. Viorel Popescu is an Associate Research Scientist at Columbia University (USA) and University of Bucharest, Romania. Prior to Columbia University, he was an Associate Professor of Conservation Biology at Ohio University, USA. He obtained an MSc from the State University of New York (2007), and a PhD in Wildlife Ecology from the University of Maine (2011). His research focuses on understanding animal population responses to human disturbance with the ultimate goal to inform conservation strategies and develop biodiversity monitoring programs. His research group uses quantitative and spatial ecology methods and a combination of experimental and observational approaches to evaluate the mechanistic responses of animal populations and communities to human impacts. Dr. Popescu is a life member of the Society for Conservation Biology and a member of the IUCN Bear Specialist Group. He is currently a CAS PIFI Fellow at Kunming Institute of Zoology and was awarded a "Xingdian Plan" grant 2024-26.
