Proportions and distribution of mass in the hindlimbs of neognath birds
Meeting Abstract P3.105 Sunday, Jan. 6 Proportions and distribution of mass in the hindlimbs of neognath birds KILBOURNE, B.M.; Friedrich-Schiller-Universität Jena brandon.kilbourne@uni-jena.de While scale effects on avian hindlimb segment lengths and proportions have been studied in depth, the influence of size upon the proportions of segment masses remains unexplored. Furthermore, it is also unknown how individual segment […]
Prey Plasticity and Life History Responses to a Native and Nonnative Predator
Meeting Abstract P3.60 Sunday, Jan. 6 Prey Plasticity and Life History Responses to a Native and Nonnative Predator HOOKS, AP; Stony Brook University hooksap@gmail.com Phenotypic plasticity in response to environmental stimuli is exceedingly common across systems and taxa. For instance, predation risk in many gastropods can induce a variety of defenses including growing thicker shells, growing shells […]

Ontogenesis of Group Regulatory Behavior in Mouse Litters
Meeting Abstract P3.23 Sunday, Jan. 6 Ontogenesis of Group Regulatory Behavior in Mouse Litters SHELTON, DS*; ALBERTS, JR; Indiana University-Bloomington; Indiana University-Bloomington delsshel@indiana.edu Individual developmental trajectories are shaped by social stimuli (e.g., parental care, dominance relations), and environmental cues (e.g., light, temperature, food). In theory, both kinds of cues should also affect group behavior that emerges from […]
