 Mating of Decapod Crustaceans\n\n\n\nSpeaker: Dr. Charles Derby\, Georgia 
 State University\n\n\n\nAbstract: Decapod crustaceans such as lobsters and
  crabs have highly organized peripheral and central chemosensory systems. 
 One of these systems is a sophisticated olfactory sense mediated by aesthe
 tasc sensilla on their first pair of antennae\, whose sensors connect to t
 he olfactory lobes in the brain.  I will discuss four examples of the use 
 of this olfactory sense in detecting chemical signals that help decapods s
 olve daily problems in their lives. Three examples are from the Caribbean 
 spiny lobster\, Panulirus argus\, which is a social species that often liv
 es in aggregations during the day and forages at night. These behaviors ar
 e gregarious sheltering based on conspecific urine signals\, alarm respons
 es mediated by conspecific blood\, and modulation of aggression during soc
 ial interactions using urine-based social signals. The fourth topic is the
  use of sex pheromones in courtship and mating in blue crabs\, Callinectes
  sapidus. Our experimental approach is that of neuroecology\, which includ
 es identifying bioactive compounds\, studying how these cues are used in m
 odulating behavior\, detailing the sensory and neural basis for these beha
 viors\, and understanding how evolution shapes these processes.
