Quantifying and developing the science surrounding biological diversity


My interest in the quantification, delineation, assessment, and monitoring of biological diversity began with my membership in and Chair-ship of the Biological Diversity Working Group of The Wildlife Society. The terms biodiversity and biological diversity have spawned literally hundreds of different definitions in the scientific literature, owing to the attractiveness of the concept as a holistic paradigm to organize conservation and management efforts – an alternative to piecemeal, reactive approaches. Subsequently, I versed myself on much of the relevant literature, and was invited as a speaker on numerous aspects of the topic (e.g., scale relevance, multivariate characterizations, analysis of trend, challenges and solutions). The science had previously remained poorly defined and specified. Across several publications, I crafted a group of statistical, design, and other resources that could be used to efficiently and effectively characterize biological diversity, in numerous contexts.
