Brian Irwin, PhD
Assistant Unit Leader - Georgia Cooperative Fish and Wildlife Research Unit
Research Interests
My research interests are in the areas of ecological change, fish population dynamics, and decision making linked to conservation and management of natural resources. Current projects involve using quantitative models to explore how populations respond to anthropogenic and natural influences.
Teaching Interests
My courses introduce concepts and analyses relevant to conservation decision making and sustainable use of exploited natural resources.

Consideration of reference points for the management of renewable resources under an adaptive management paradigm Consideration of reference points for the management of renewable resources under an adaptive management paradigm
The success of natural resource management depends on monitoring, assessment and enforcement. In support of these efforts, reference points (RPs) are often viewed as critical values of management-relevant indicators. This paper considers RPs from the standpoint of objective-driven decision making in dynamic resource systems, guided by principles of structured decision making (SDM) and...

Estimating spatial and temporal components of variation in count data using negative binomial mixed models Estimating spatial and temporal components of variation in count data using negative binomial mixed models
Partitioning total variability into its component temporal and spatial sources is a powerful way to better understand time series and elucidate trends. The data available for such analyses of fish and other populations are usually nonnegative integer counts of the number of organisms, often dominated by many low values with few observations of relatively high abundance. These...
