Systematics and Ecology of Shell-Boring Polychaetes from New England

Ecology and biology of chemoreception in polychaetes

Nervous system and sensory structure morphologies provide useful information for reconstructing phylogenetic relationships among the Polychaeta, Annelida, and Arthropoda. With the more common use of indirect immunocytochemistry and laser scanning confocal microscopy methods, the detailed information available from morphological studies has increased. Despite this wealth of information, developi...

Chemical Ecology of Wood-boring Insects

The roles and chemistry of pheromones that mediate reproductive behaviors of cerambycid beetles have received remarkably little attention, given the economic importance of many cerambycid species. Until recently, very few volatile sex pheromones and nonvolatile contact pheromones had been identified. However, that situation is changing rapidly, with the number of identified pheromones more than...

Insights from historical geography to ecology and conservation: lessons from the New England landscape

In these days of supercomputer-based global climate models, large ecosystem experiments including Biosphere II, and aircraft-borne sensors of ozone holes, it is often overlooked that many fundamental insights into ecological processes and major environmental issues come not through reductionist or high tech studies of modern conditions but from thoughtful consideration of nature’s history (Fost...
