AMUNDSON, R; Univ of Hawaii at Hilo: Why are developmental constraints “constraints”? The study of developmental constraints is one of the enduring factors within the late twentieth century research traditions that grew into evo-devo. Developmental constraint has been fruitfully applied in a wide variety of contexts. For many years, an evolutionist�s position on the �adaptation […]

SERB, J.M.; OAKLEY, T.H.; Univ. of California, Santa Barbara; Univ. of California, Santa Barbara: Reconciled phylogenetic trees as an emerging analytical framework for evolutionary developmental biology The field of evolutionary developmental biology has been criticized for its lack of an explicit unifying analytical framework. We suggest that such a framework may exist in the form […]

KAVANAGH, K.D.*; Harvard University and Univ. of Helsinki, Finland: Embedded Molecular Switches, Anti-Cancer Selection, and Effects on Ontogenetic Rates: A Hypothesis of Developmental Constraint on Morphogenesis and Evolution The switch between the cell cycle and the progress of differentiation in developmental pathways is prevalent throughout the eukaryotes in all major cell lineages. Disruptions to the […]

CROSBY, Kevin C.; BURIAN, Richard M.; WOJCIK, Edward J.; Virginia Polytechnic Institute and State University; Virginia Polytechnic Institute and State University; Virginia Polytechnic Institute and State University: Donald Poulson and the Consolidation of Drosophila Developmental Genetics We examine Donald Poulson�s work on the genetics of early development of Drosophila in the 1930s-1950s. This work, not […]

MU�OZ-GARCIA, Agust�*; RO, Jennifer; BROWN, Johnnie C.; WILLIAMS, Joseph B.; Ohio State University; Ohio State University; Applied Biosystems; Ohio State University: Sphingolipids in the stratum corneum and their relationship with cutaneous water loss in House sparrows, Passer domesticus, from arid and mesic environments Lipids in the intercellular spaces in the vertebrate stratum corneum (SC), the […]

BRONIKOWSKI, Anne M.*; BRUNET-ROSSINNI, Anja K.; ARNOLD, Stevan J.; Iowa State University; University of Wisconsin, LaCrosse; Oregon State University: Physiological evolution and aging in garter snakes A primary theory on the evolution of senescence purports that different rates of aging may have evolved as part of a suite of co-evolved life-history traits involving trade-offs in […]

AGUILAR-ROCA, Nancy M.*; MOORE, Francisco B. -G.; SCHLUMBOHM, Jason P.; BENNETT, Albert F.; University of California, Irvine; University of Akron; University of California, Irvine; University of California, Irvine: Methionine biosynthesis limits adaptation to high temperature in Escherichia coli In Escherichia coli, degradation of the first enzyme in the methionine biosynthesis pathway may be a critical […]

TRACY, Christopher R.*; CHRISTIAN, Keith A.; BETTS, Greg; TRACY, C. Richard; Charles Darwin University; Charles Darwin University; Charles Darwin University; University of Nevada Reno: Interactions between water balance, temperature regulation and arboreality in frogs Many amphibians evaporate water freely across their skin. This creates a challenge to thermoregulation: how to simultaneously regulate water and temperature […]

WILLIAMS, J. B.*; OSTROWSKI, S.; Ohio State Univerisity; University of Lyon: Heterothermy of free-living Arabian sand gazelles (Gazella subgutturosa marica) in a desert environment One mechanism, thought to be important in reducing evaporative water loss among large desert ungulates, is heterothermy, the storage of body heat during the day and dissipation of this heat at […]
