Meeting Abstract P2.205  Saturday, Jan. 5  Geographic variation in morphology of dark-eyed juncos and implications for population divergence FERREE, E.D.; Claremont Colleges, CA eferree@kecksci.claremont.edu When geographic variation in morphology develops among closely related populations, it can help drive genetic divergence, and eventually speciation, when those morphological traits are the basis for social interactions that influence reproduction. The […]

Meeting Abstract P2.127  Saturday, Jan. 5  Functional morphology of the smallest ballistic tongue ISRAEL, S.*; DEBAN, S.M.; Univ. of South Florida, Tampa; Univ. of South Florida, Tampa segalli@mail.usf.edu An elastic-recoil mechanism in the tongue-projection system has evolved independently in three lineages of plethodontid salamanders. This mechanism increases performance and provides thermal insensitivity to projection, allowing an advantage […]

Meeting Abstract P2.54  Saturday, Jan. 5  Functional morphology of dorsal acoustic structures in pygmy (Kogia breviceps) and dwarf (K. sima) sperm whales THORNTON, S.W.*; MCLELLAN, W.A.; ROMMEL, S.A.; PABST, D.A.; Univ. of North Carolina Wilmington swt9459@uncw.edu Odontocete cetaceans produce echolocation clicks to interrogate their environment and search for prey. These clicks are generated by pneumatically-driven phonic lips […]

Meeting Abstract P2.115  Saturday, Jan. 5  Functional morphology and efficiency of the antenna cleaner in Camponotus rufifemur ants HACKMANN, A*; FEDERLE, W; University of Cambridge; University of Cambridge ah658@cam.ac.uk In the course of evolution insects have developed a variety of strategies to reduce surface contamination, which can inhibit physiological functions. For example, many insects regularly clean their […]
