Meeting Abstract 48-3 Tuesday, Jan. 5 10:45 Sexual selection on skeletal shape in Carnivora MORRIS, J.S.*; CARRIER, D.R.; University of Utah; University of Utah j.s.morris@utah.edu Because lifetime reproductive success is often dependent upon the ability to compete for mates, males tend to be more specialized for physical competition than females. Among mammals, polygyny enforced by male-male competition […]

Can we detect a physiological signature of cost of reproduction
Meeting Abstract 48-1 Tuesday, Jan. 5 10:15 Can we detect a physiological signature of cost of reproduction? WILLIAMS, TD*; FOWLER, MA; Simon Fraser Univ., Burnaby; Springfield College, MA tdwillia@sfu.ca http://www.sfu.ca/biology/faculty/williams/ Increased investment in current reproduction can have a negative influence on survival to, or future fecundity of, a subsequent breeding attempt. Life-history theory predicts that current and […]
When do locomotor appendages get complicated
Meeting Abstract 48-3 Friday, Jan. 6 10:50 – 11:00 When do locomotor appendages get complicated? REVZEN, S; U Michigan, Ann Arbor shrevzen@umich.edu http://www.birds.eecs.umich.edu Some animals contact the substrate on which they move using simple appendages — limbs with few degrees of freedom, which interact with the substrate with what is effectively a single rigid contact, such as […]
