Title: Spatial Occupancy Models and Capture-Recapture Models in Applied Ecological Research

Abstract: Two of the most widely used classes of models for studying and monitoring wildlife populations are occupancy models and capture-recapture models. Until recently, however, these methods were not spatially explicit, limiting their utility for studying ecological processes such as dispersal and connectivity – processes that can strongly influence spatial variation in density and population viability. I will present an overview of new developments in spatial modeling and demonstrate their utility using examples from ongoing research projects on desert-breeding amphibians in the Sonoran desert and carnivores in the southeastern US.
Bio of Speaker: Dr. Chandler is an Assistant Professor of wildlife ecology and management at the University of Georgia’s Warnell School of Forestry and Natural Resources. He received his BS in Wildlife Biology from the University of Vermont. He obtained his MS and PhD degrees in Wildlife Conservation at the University of Massachusetts during which time he studied the effects of forest management and coffee production methods on migratory birds. He spent three years as a post-doc at the USGS Patuxent Wildlife Research Center developing statistical models and R packages for inference about population dynamics. Recently, he co-authored a book on spatially explicit capture-recapture methods. His ongoing research projects include studies of desert

Title: A Quantitative Assessment Framework for Potential Climate Change Impacts on National Hydropower Generation

Abstract: Hydropower generation is mainly influenced by stream flow availability, which may be directly affected by climate change and variability. Using a series of hydro-climatic models and statistical techniques, including General Circulation Models (GCMs), Regional Climate Models (RCMs), bias correction techniques, Hydrological Models (HMs), historic runoff-generation relationships and a newly-organized national hydropower dataset, a regional assessment framework is being developed to quantify the potential climate change impacts on hydropower generation to support decisions on future hydropower marketing and contracting activities. Efforts are undertaken to refine the spatial resolution, enhance the model calibration, and investigate new regional water balance approaches that incorporates water storage and competing water uses to provide better understanding of future conditions and improve mitigation strategies.

 

Bio of Speaker: Dr. Shih-Chieh Kao is a statistical hydrologist in the Environmental Sciences Division and Climate Change Science Institute at Oak Ridge National Laboratory (ORNL). He earned his Bachelor of Science and Master of Science degrees in civil engineering from National Taiwan University, Taiwan, in 1999 and 2001, and a Doctor of Philosophy degree in civil engineering from Purdue University, USA, in 2008. His PhD dissertation, “Multivariate Statistical Analysis of Indiana Hydrologic Data”, was awarded as the Purdue Civil Engineering Best Dissertation in the year of 2008. His areas of research expertise include hydrologic extremes, multivariate statistical analysis, supercomputing, climate change impact assessment, and hydropower resource evaluation. Dr. Kao joined ORNL in 2009 as a post-doctoral research associate and was promoted to research scientist in 2010. He is currently the principal investigator for several U.S. Department of Energy funded research projects focusing on national hydropower resource assessment, climate change impact on hydropower, and regional-scale hydro-climate simulation. Dr. Kao is a frequent reviewer for a number of science journals, and was awarded as an Outstanding Reviewer for the Journal Hydrologic Engineering, ASCE, at 2009. He recently received the ICSH-STAHY 2013 Best Paper Award jointly with Dr. Rao S. Govindaraju from Purdue University for their drought analysis paper published in Journal of Hydrology in 2010.
