Meeting Abstract 14.1  Wednesday, Jan. 4  Pecking at the Origin of Morphological Diversity: Insights from Darwin’s Finches and Other Birds ABZHANOV, A; Harvard University, Cambridge abzhanov@fas.harvard.edu The faces of vertebrates display a number of species-specific and adaptive characteristics, which they acquired during evolution by natural selection. The classic textbook example of adaptive radiation, natural selection and niche […]

Meeting Abstract 14.3  Wednesday, Jan. 4  Evolution and Development of Sexual Skull Dimorphism among Anolis lizards SANGER, Thomas J.*; SEAV , Susan M.; LOSOS, Jonathan B.; ABZHANOV, Arhat; Harvard University tsanger@oeb.harvard.edu Many species exhibit striking sexual dimorphisms in body size and shape. Sexual body size dimorphism is well studied in many biological contexts – ecological, evolutionary, and […]

Meeting Abstract 13.6  Wednesday, Jan. 4  The mechanism of rapid, plastic hatching in red-eyed treefrogs COHEN, K.L.*; SEID, M.A.; WARKENTIN, K.M.; Boston Univ.; Univ. of Scranton; Boston Univ. kcohen@bu.edu Although environmentally cued hatching is common and widespread in animals, including 12 families of amphibians, mechanistic studies treat hatching as a fixed developmental process. The treefrog Agalychnis callidryas […]

Meeting Abstract 13.3  Wednesday, Jan. 4  Hoxa13 gene expression is associated with tail growth across embryonic, larval, and adult development in the non-model salamander Eurycea cirrigera REDMOND, SB*; BOTTS, EA; HILL, KL; EVANS, PK; VAGLIA, JL; DePauw University; DePauw University; DePauw University; DePauw University; DePauw University sarahredmond@depauw.edu Regulatory Hox gene expression is important throughout organismal development to […]

Meeting Abstract 13.5  Wednesday, Jan. 4  Does temperature dependence of morphogenesis require fine control of tissue mechanics? VON DASSOW, M*; DAVIDSON, LA; Univ. of Pittsburgh; Univ. of Pittsburgh mvondass@gmail.com Understanding morphogenesis requires deciphering how organisms withstand environmental perturbations. Environmental temperature strongly affects developmental rates but previous studies suggest that temperature does not affect the relative timing of […]

Meeting Abstract 13.2  Wednesday, Jan. 4  Developmental evidence that the metatarsals and phalanges are distinct modules WINSLOW, B. B.*; LEARY, B.; KAVANAGH, K.; University of Massachusetts Dartmouth bwinslow@umassd.edu Historically metatarsals and phalanges have been considered as evolutionarily independent skeletal units in the autopod because of their functional and variational differences. However, during ontogeny these bones appear to […]
