Research interests:
My studies focus on interactions between invertebrates and their environment, and how human activities and environmental changes affect these interactions. Initially I studied macrobenthic populations of coastal habitats and on continental shelves. This research often was conducted in response to observed, suspected or anticipated environmental changes, like eutrophication, pollution, or over-exploitation of natural resources. An example for such studies is the trawling experiment on the Grand Banks of Newfoundland after the collapse of the Atlantic cod stocks in the early 1990s, in which we determined the impact of various types of fishing gear on sediment properties and the benthic food web. In many cases, these were high priority projects addressing environmental issues with enormous social and economic implications. Since the mid 1990s, my research interest has moved more and more to weevils, a hyperdiverse group of beetles with great economic importance. One subfamily in particular stirred my curiosity when I discovered that the included species have fascinatingly diverse and sophisticated biologies. Because of their highly adapted life strategies, many are known only from a few accidentally collected specimens. The contrast between ecological diversity and morphological uniformity opened up a promising new approach to resolve taxonomic issues. I was fortunate to conduct extensive fieldwork in Latin America, where these weevils are particularly diverse. With the help of expert botanists, I began to systematically explore weevil-plant associations and life strategies. Under the US Department of Agriculture, the focus of my research shifted to invasive and agriculturally important weevils. Ever tried to identify a weevil from just anywhere in the world within ten minutes? My research attempts to provide the necessary knowledge and tools to make this possible.
