Physiol Biochem Zool 74:520-30. 2001..However, there was no significant relationship between the rate of aging, as indicated by the rate of increase in water-loss rates as flies aged, and either habitat or age of maturity... - Evolution of water balance in the genus DrosophilaA G Gibbs
Center for Insect Science and Department of Ecology and Evolutionary Biology, 1041 E Lowell Street, University of Arizona, Tucson, AZ 85721, USA

Department of Ecology and Evolutionary Biology and Center for Insect Science, 1041 E Lowell Street, University of Arizona, Tucson, AZ 85721, USA
Comp Biochem Physiol A Mol Integr Physiol 133:781-9. 2002..Different physiological and behavioral strategies may evolve depending upon the particular options available in the environment... - Evolution of water conservation mechanisms in DrosophilaAllen G Gibbs
Department of Ecology and Evolutionary Biology, 1041 E Lowell St, University of Arizona, Tucson, AZ 85721, USA
J Exp Biol 206:1183-92. 2003..They were also more likely to exhibit a pattern of cyclic CO(2) release that may help to conserve water. We conclude that lower overall rates of water loss are achieved primarily by reduction of respiratory losses... - Effects of starvation and desiccation on energy metabolism in desert and mesic DrosophilaM T Marron
Department of Ecology and Evolutionary Biology, University of Arizona, 1041 E. Lowell St, Tucson, AZ 85721, USA
J Insect Physiol 49:261-70. 2003..Cactophilic Drosophila did not have greater initial amounts of reserves than mesic species, but may have lower metabolic rates that contribute to stress resistance... - Physiological mechanisms of evolved desiccation resistance in Drosophila melanogasterA G Gibbs
Department of Ecology and Evolutionary Biology, University of California, Irvine 92697, USA
J Exp Biol 200:1821-32. 1997..Thus, evolution of increased desiccation resistance has occurred by multiple physiological mechanisms, but some potential adaptive differences have not evolved... - Laboratory selection for the comparative physiologistA G Gibbs
Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, AZ 85721, USA
J Exp Biol 202:2709-18. 1999..I outline here recent results (including success stories and caveats for the unwary investigator) and potential directions for selection experiments in comparative physiology... - Osmoregulation in Drosophila melanogaster selected for urea toleranceV A Pierce

School of Life Sciences, Arizona State University, Tempe AZ 85287 4501, USA
J Insect Physiol 50:943-53. 2004..Our data support the hypothesis that part of this increase results from soil particles abrading the cuticle during the process of nest excavation... - Selection for desiccation resistance in adult Drosophila melanogaster affects larval development and metabolite accumulationEran Gefen
Department of Biological Sciences, University of Nevada, Las Vegas, 89154 4004, USA
J Exp Biol 209:3293-300. 2006..The contribution of third instar feeding to desiccation resistance of adult selected flies is higher than that of controls. Thus, selection for adult stress resistance has resulted in correlated changes in larval physiology... - Cuticular pheromones and water balance in the house fly, Musca domesticaKristi L Montooth
Department of Molecular Biology and Genetics, Cornell University, 227 Biotechnology Building, Ithaca, NY 14853, USA
Comp Biochem Physiol A Mol Integr Physiol 135:457-65. 2003..We propose a working model in which phase separation between the unsaturated female pheromone and saturated hydrocarbons results in areas of melted, pheromone-rich lipids and regional variation in cuticular permeability... - Discontinuous gas exchange in insects: a clarification of hypotheses and approachesSteven L Chown
Spatial, Physiological, and Conservation Ecology Group, Department of Botany and Zoology, University of Stellenbosch, Private Bag X1, Matieland 7602, South Africa

Respir Physiol Neurobiol 154:18-29. 2006..We are pleased to report that what was once a mature discipline, in which the broad parameters and adaptive significance of discontinuous gas exchange were thought to be well understood, is now a thriving and vigorous field of research... - Natural variation in food acquisition mediated via a Drosophila cGMP-dependent protein kinaseKarla R Kaun
Department of Biology, University of Toronto, 3359 Mississauga Road, Mississauga, Ontario, L5L 1C6, Canada
J Exp Biol 210:3547-58. 2007..Together, these results show that natural variation in for has far reaching implications affecting a suite of phenotypes involved in the regulation of food acquisition...
