LIUBICICH, Danielle M.*; SERANO, Julia M.; PATEL, Nipam H.; University of California, Berkeley/HHMI; University of California, Berkeley/HHMI; University of California, Berkeley/HHMI: Functional approaches to understanding the role of hox genes in specifying crustacean appendage identity Specialization of crustacean trunk appendages may require the presence and absence of certain hox genes. Hox genes are highly conserved […]

EBANKS, S.C.*; BRIX, K.V.; GROSELL, M.; University of Miami, RSMAS; University of Miami, RSMAS; University of Miami, RSMAS: Extra-cellular Volume and Solute Recovery in the Pond Snail Lymnaea stagnalis After Simulated Predatory Attack To fully retract into its shell and reduce the risk of predation, the pond snail Lymnaea stagnalis releases as much as 40-60% […]

GREWAL, A.K*; SIBLE, J; BELDEN, L.K; Virginia Tech, Blacksburg Va; Virginia Tech, Blacksburg Va; Virginia Tech, Blacksburg Va: Examining developmental responses to environmental insults in early stage amphibian embryos Amphibian population declines remain a major concern among ecologists and scientists around the world. Some of these declines may occur due to embryonic mortality in response […]

STAAB, KL*; HERNANDEZ, LP; George Washington University: Evolutionary developmental biology of the kinethmoid: Using zebrafish to investigate the development and evolution of a unique mechanism of premaxillary protrusion The use of the zebrafish in the study of craniofacial development has yielded an enormous amount of data relevant to biomedical research. Thus the majority of the […]

Their ability […]

SPARKMAN, A.M.*; ARNOLD, S.J.; BRONIKOWSKI, A.M.; HERRIGES, M.J.; Iowa State University, Ames; Oregon State University, Corvallis; Iowa State University, Ames; Ames High School, Ames: Evolutionarily divergent patterns of age-specific reproduction in the garter snake Thamnophis elegans Evolutionary ecology studies of garter snakes (Thamnophis elegans) in the vicinity of Eagle Lake (Lassen County) California have reported […]

HOFFMAN, G.G.; SONA, S.*; ELLINGTON, W.R.; Florida St. Univ., Tallahassee: Evolution of the Octameric State in Mitochondrial Creatine Kinases Mitochondrial creatine kinase (MtCK) in protostomes, deuterostome invertebrates, protochordates and vertebrates exists primarily in the octameric state under physiological conditions. The octamer is thought to �bridge� contact site formation in the intermembrane space thereby creating a […]

ROGERS, S.A.*; CHANG, Y.; Arizona State University; Arizona State University: Evolution of Regulatory Elements that Control Tissues-Specific Expression of Recombination Activation Genes Tracking the evolution of cis-regulatory sequences is a difficult task because of the lack of knowledge about the structure of these elements and their relationship to their function. Gaining a better understanding of […]

SHAW, Barbara J.*; RUEDAS, Luis A.; Portland State University; Portland State University: Evolution of Order Xenarthra modality distinct from all other mammals The mammalian clade Xenarthra (formerly Order Xenarthra, split into 1) Order Pilosa including anteaters, ground and tree sloths, and 2) Order Cingulata including glyptodonts, pampatheres and armadillos) constitutes a bizarre and fascinating group […]

HULSEY, CD*; FRASER, GJ; STREELMAN, JT; Georgia Tech; Georgia Tech; Georgia Tech: Evolution and Development of Complex Biomechanical Systems: 300 Million Years of Fish Jaws and Teeth We discuss the comparative developmental genetics of oral and pharyngeal jaws of teleost fishes. The insights possible from comparative studies are discussed in the context of zebrafish and […]
