My research makes use of species distribution models to document and understand human-induced changes in the occurrence of individual species and in patterns of biodiversity. Species distribution models identify statistical relationships between species occurrence on the one hand and environmental and anthropogenic factors on the other. They are thus useful tools in estimating the likelihood of species occurrence where survey data are lacking, and can provide useful clues as to the causes of distributional change.
My previous research has ranged from studying the international trade in seahorses to modeling the distributions of 1500 bird species in southern and eastern Africa. More details and a list of publications are available on my website.
The Census of Marine Life is a growing global network of researchers in more than 45 nations engaged in a ten-year initiative to assess and explain the diversity, distribution, and abundance of marine life in oceans--past, present, and future.
