His presentation is called, =B3Determination and measurement of local biodiversity=B2=20 =20 Abstract: Local biodiversity refers to the collection of species we experience every day. How did those species get there, what factors determine their relative abundances, and how do we measure and compare the number of species between sites? This talk will discuss some answers to these questions, using theory, experiments, and meta-analysis. An experimental test using a species-rich community of microarthropods will be presented, which examines the local community consequences of changes in regional species richness and composition. Results demonstrate the complicated interactions between assembly time, seasonality, and regional species pools in structuring local species richness and composition in this community. The second part of the talk will consider a question of importance to conservation biologists in the field: how best to allocate scarce resources when attempting to uncover changes in biodiversity between sites. The results of this study are pertinent in field situations: under many realistic scenarios, statistical power (to detect changes in causes an= d structure of local biodiversity) may be maximized by eliminating difficult species from a survey in order to increase the number of sites surveyed. =20 Brian did his undergrad at StFX, an MSc here at Acadia with Soren Bondrup-Neilsen, and a PhD in zoology at the UBC. He works as a community ecologist, studying the factors that control the number of species seen in local patches. His work recent work has been conducted in Costa Rica, the coastal rainforests of British Columbia, and the sub- and high arctic of Canada.=20 =20 ** Seminars take place Thursdays from 11:30 to 12:30 in PAT 308.
