Male-Male Competition’s Influence on Primate Brain Size
Meeting Abstract 96.1 Wednesday, Jan. 7 Male-Male Competition’s Influence on Primate Brain Size CUNNINGHAM, C. B.*; CARRIER, D. R.; Universtiy of Utah; University of Utah c.cunningham@utah.edu Primates have evolved large brains. We hypothesized that male-male competition has helped drive the enlargement of the primate brain because competition demands extensive cognitive and physical interactions between opponents. Both the […]
How similar are aquatic Anolis lizards a detailed ecological and behavioral analysis of two Costa Rican species (A oxylophus and A aquaticus)
Meeting Abstract 96.2 Wednesday, Jan. 7 How similar are aquatic Anolis lizards: a detailed ecological and behavioral analysis of two Costa Rican species (A. oxylophus and A. aquaticus). MUNOZ, Martha/M*; HERREL, Anthony; SASA, Mahmood; LOSOS, Jonathan; Harvard University mmunoz@fas.harvard.edu Anolis lizards of the Greater Antilles have become a model system for the study of adaptive radiations as […]
Calcium Provision to Embryos of the Reproductively Bimodal Lizard, Lacerta vivipara
Meeting Abstract 96.3 Wednesday, Jan. 7 Calcium Provision to Embryos of the Reproductively Bimodal Lizard, Lacerta vivipara STEWART, J.R.*; ECAY, T.W.; HEULIN, B.; East TN State Univ; East TN State Univ; Station Biologique de Paimpont stewarjr@etsu.edu Squamate reptiles provide opportunity to study the relationship between reproductive mode and pattern of embryonic nutrition because viviparity has evolved in […]
Predation at a snail&39;s pace time-lapse photography and analysis of predatory mode in neogastropod whelks
Meeting Abstract 96.1 Thursday, Jan. 7 Predation at a snail's pace: time-lapse photography and analysis of predatory mode in neogastropod whelks VENDETTI, Jann E.*; FAY, Scott A.; Univ. of California, Berkeley; Univ. of California, Berkeley jannv@berkeley.edu Time-lapse photography has been used to elucidate and digitally capture diverse biological phenomena across the tree of life. Within the Gastropoda, […]
Isometric scaling of lever arm lengths in squirrel jaws leaves jaw shape free to meet diverse functional demands
Meeting Abstract 96.3 Thursday, Jan. 7 Isometric scaling of lever arm lengths in squirrel jaws leaves jaw shape free to meet diverse functional demands SWIDERSKI, D.L.*; ZELDITCH, M.L.; Univ of Michigan, Ann Arbor; Univ of Michigan, Ann Arbor dlswider@umich.edu Allometric scaling appears to be a nearly universal feature of morphological diversity, with the conspicuous exception of the […]
Can functional complexity mitigate performance trade-offs An evolutionary analysis
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 […]
Prolactin as a mediator of the stress response in parent birds an underappreciated mechanism
Meeting Abstract 96.2 Saturday, Jan. 7 Prolactin as a mediator of the stress response in parent birds: an underappreciated mechanism ANGELIER, F*; CHASTEL, O; CEBC, CNRS, France; CEBC, CNRS, France angelier@cebc.cnrs.fr In birds, an emergency life-history stage (ELS) is expressed when the immediate survival is threatened by stressful events. This ELS redirects the individual away from the […]
Physiological stress responsiveness is transferable from parent to offspring in free-living Florida Scrub-Jays
Meeting Abstract 96.3 Saturday, Jan. 7 Physiological stress responsiveness is transferable from parent to offspring in free-living Florida Scrub-Jays SMALL, Thomas W*; BRIDGE, Eli; SCHOECH, Stephan; University of Memphis; University of Oklahoma; University of Memphis twsmall@memphis.edu The rapid stress induced elevation of plasma glucocorticoids is well documented in a variety of animals. In Florida Scrub-Jays (Aphelocoma coerulescens) […]
Parental behavior and corticosterone during the breeding season in eastern bluebirds ( Sialia sialis)
Meeting Abstract 96.1 Saturday, Jan. 7 Parental behavior and corticosterone during the breeding season in eastern bluebirds ( Sialia sialis) DAVIS, J.E.*; GUINAN, J.A.; Radford University; Radford University jdavis319@radford.edu Breeding animals face a trade-off between investment in self and investment in offspring; too much investment in self can reduce offspring survival and fitness, while too much investment […]
