Thu 13 Mar 2008: 2pm - Rittschof on "Cementing Relationships: Pheromones and Signals in Crustaceans and Mollusks"

Category : talks

Abstract: Communication, especially communication that controls behavior vital to survival has evolved in all animals. Many highly specific communication molecules are peptides that are generated by the most ubiquitous and ancient proteolytic enzymes such as trypsin-like serine Proteases. We will explore some critical behaviors and support the hypothesis that a huge family of communication molecules evolved as byproducts of essential processes like glue polymerization and shell formation.

About the Speaker: Prof Rittschof is Professor of Zoology at Duke University’s Nicholas School of the Environment. Basic studies in his lab include chemically-mediated and physiologically regulated breeding and spawning behaviors of behaviors of crustaceans and mollusks, such as organization of spawning, breeding navigation and movement behavior by kairomones and pheromones; hormonal and metabolic modulation of behavior and signaling uses of volatile compounds by marine organisms. Dr Rittschof is interested in signaling peptides and substituted amino sugars and disruption of signaling transduction cascades by pharmaceuticals and biocides. The ultimate goal of these studies is an understanding of the mechanisms and evolution of signaling systems. Current projects include studies on barnacle adhesion, impacts of biocide boosters on reproduction of target and non target species; and studies on a variety of aspects of ecology and reproduction of blue crabs. Prof Rittschof is Visiting Research Professor at TMSI.
