GEE, JM; GEE, ; GEE, ; GEE, ; GEE, ; GEE, ; GEE, ; GEE, ; Cornell University: GREGARIOUS SPECIES AND THE TENDENCY TO HYBRIDIZE Many studies have revealed the circumstances that create hybrid zones, such as secondary contact between once isolated species. Others have shown how dispersal and selection maintain hybrid zones and limit […]

M.; Royal Veterinary College, London, UK; Royal Veterinary College, London, UK; Royal Veterinary College, London, UK; Royal Veterinary College, London, UK; Royal Veterinary College, London, UK: Functional specialisation of the thoracic and pelvic limb in horses Proximal-to-distal functional specialisation of […]

HOCHBERG, R; Smithsonian Marine Station, Fort Pierce, FL.: Functional morphology of jumping appendages in planktonic Rotifera: Ultrastructure and neuromuscular control of spines in Filinia longiseta Filinia longiseta is a planktonic rotifer common in lentic systems. The species possesses paired, elongate lateral spines that function in saltatory sweeping motions in response to sheer disturbances by predators. […]

DEBAN, S/M*; FISCHBEIN, T; STAKEBAKE, E/F; CARRIER, D/R; University of Utah; University of Utah; University of Utah; University of Utah: Function of the Forelimb Extrinsic Appendicular Muscles in Trotting Dogs The forelimbs of mammals are attached to the axial skeleton by a complex system of extrinsic appendicular muscles. In this study, we elicited changes in […]

GELLER, J; MEYER, C; PAULAY, G; Moss Landing Marine Laboratories; University of Florida; University of Florida: Fine scale endemism on coral reefs: archipelagic differentiation of turbinid gastropods. The perceived wide geographic range of organisms in the sea, facilitated by ready dispersal of waterborne dispersal stages, is a challenge for hypotheses of marine speciation but a […]

WALTON, L J; TUNNACLIFFE, A; University of Cambridge, UK; University of Cambridge, UK: Expression of a nematode LEA protein in mammalian cells improves tolerance to hyperosmotic shock The late embryogenesis abundant (LEA) proteins are expressed in a number of anhydrobiotic organisms in response to dehydration stress. They are postulated to play a role in desiccation […]

WAGNER, Emily; WILLIAMS, Tony D; Simon Fraser Univ., Burnaby; Simon Fraser Univ., Burnaby: Experimental manipulation of the egg size:offspring quality relationship In many oviparous taxa there is a strong, positive relationship between egg size and offspring growth or survival, but in birds there is surprisingly little empirical evidence for such a relationship (in part due […]

HUGHES, Bradley/S; CULLUM, Alistair/J; BENNETT, Albert/F; Univ. of California, Irvine; Creighton University; Univ. of California, Irvine: Experimental Evolutionary Adaptation to Environmental pH in the Bacterium Escherichia coli Abstract: the evolutionary responses of organisms to changes in environmental factors such as temperature and pH have been of longstanding interest, because they are naturally variable and can […]

GIBBS, Allen G.; VANIER, Cheryl H.; Univ. of Nevada, Las Vegas; Univ. of Nevada, Las Vegas: Evolution of water balance and gene expression in desiccation-selected Drosophila melanogaster Because of their small size and large surface-area-to-volume ratio, insects face significant problems in maintaining positive water balance. These problems are particularly severe in arid environments such as […]
