Meeting Abstract 96.2  Thursday, Jan. 7  Can functional complexity mitigate performance trade-offs? An evolutionary analysis HOLZMAN, R*; COLLAR, DC; MEHTA, RS; WAINWRIGHT, PC; UC Davis; Harvard; UC Davis; UC Davis raholzman@ucdavis.edu The parts of organisms (genes, molecules, and anatomical structures) typically participate in multiple organismal functions. Multiple roles bring about trade-offs because changes to individual traits that […]

Meeting Abstract 95.2  Thursday, Jan. 7  How do chitons see their world? A new sensory organ in basal molluscs (Polyplacophora: Lepidopleurida) SIGWART, JD; Queen’s University Belfast j.sigwart@qub.ac.uk Polyplacophoran molluscs (chitons) are “primitive” animals that have a simple nerve system of non-ganglionised longitudinal nerve cords and no cephalised sense organs. Two sensory structures in the pallial cavity have […]
