Evolution of phalangeal formula in gymnophthalmid lizards patterns of character states and inferences about developmental processes
Meeting Abstract 12.4 Sunday, Jan. 4 Evolution of phalangeal formula in gymnophthalmid lizards: patterns of character states and inferences about developmental processes. GRIZANTE, MB*; KOHLSDORF, T; University of Sao Paulo, FFCLRP; University of Sao Paulo, FFCLRP tiana@usp.br Limb reduction occurred repeatedly along Tetrapod evolution, and lizards in particular are one of the best models for studying the […]

Why do we know so little about mechanisms underlying avian reproduction
Meeting Abstract 12.6 Monday, Jan. 4 Why do we know so little about mechanisms underlying avian reproduction? WILLIAMS, Tony D.; Simon Fraser Univ., Burnaby, Canada tdwillia@sfu.ca Recent evolutionary analysis of large, long-term population studies’ data has shown that the traits which contribute most to individual variation in lifetime fitness in birds are longevity, clutch size and laying […]

The evolution of “endothermy†terminological constraints and a phylogenetic analysis of metabolic rate evolution in non-mammalian therapsids
Meeting Abstract 12.2 Monday, Jan. 4 The evolution of “endothermy”: terminological constraints and a phylogenetic analysis of metabolic rate evolution in non-mammalian therapsids BATAVIA, M.P.; University of California, Berkeley mbatavia@berkeley.edu Numerous studies and reviews over the last several decades have addressed the evolution of endothermy in mammals (synapsids) and birds (diapsids). However, inconsistent usage of the term […]
The energetic costs of different components of the social display in male Brown Anoles
Meeting Abstract 12.3 Monday, Jan. 4 The energetic costs of different components of the social display in male Brown Anoles. STEFFEN, J.E.*; APPEL, A.G.; Auburn University steffje@auburn.edu Male Anoline social displays are dynamic and typically consist of several different components (e.g., head nods, dewlap extension, and two and four legged push-ups), which appear to be physically costly. […]
