Mechanical Transgressive Segregation and the Rapid Origin of Trophic Novelty
Meeting Abstract 7.1 Saturday, Jan. 4 08:00 Mechanical Transgressive Segregation and the Rapid Origin of Trophic Novelty HULSEY, CD*; HOLZMAN, R; Univ. of Tennessee, Knoxville; Tel Aviv University, Israel chulsey@utk.edu Hybrid phenotypes often fall within the parental range. However, when morphological traits are complex,hybridization can generate mechanical phenotypes that segregate transgressively. For instance, even when the morphologies […]

Body Size Evolution and Species Diversity in North American Minnows
Meeting Abstract 7.3 Saturday, Jan. 4 08:30 Body Size Evolution and Species Diversity in North American Minnows MARTIN, S. D.*; BONETT, R. M.; Univ. of Tulsa; Univ. of Tulsa samuel-martin@utulsa.edu Body size is one of the most important traits influencing an organism’s ecology and is often a major axis of evolutionary change. Among freshwater fishes, body size […]

K.; PRIYA, S.; Virginia Tech; Virginia Tech; Virginia Tech; Virginia Tech colins@vt.edu Fast-swimming hydromedusae produce the majority of their thrust by expelling pulsed jets of water from their subumbrellar […]
Simple robotic models of aquatic locomotion
Meeting Abstract 6.6 Saturday, Jan. 4 09:15 Simple robotic models of aquatic locomotion LAUDER, G. V.; Harvard University glauder@oeb.harvard.edu Robotic models of aquatic locomotion have many advantages over studying live animals, including the ability to manipulate and control individual morphological or kinematic factors that affect performance, substantially easier measurement of locomotor forces and torques, and the ability […]
