MCCORMICK, Stephen D.*; O’DEA, Michael F.; MOECKEL, Amy M.; USGS, Conte Anadromous Fish Research Center, Turners Falls MA USA; Organismic and Evolutionary Biology Program, University of Massachusetts, Amherst USA: Are we missing a mineralocorticoid in fish? Effect of corticoids and receptor inhibitors on salinity tolerance of Atlantic salmon. It has long been held that cortisol, […]

SERRAT, M.A.*; LOVEJOY, C.O.; KING, D.; Kent State University, OH; Kent State University, OH; NEOUCOM, Rootstown, OH: Age- and site-specific decline in IGF-I receptor expression and growth plate activity in the mouse hindlimb The proximal and distal growth plates of the principal long bones do not contribute equally to their longitudinal growth. Most hindlimb elongation […]

PAPASTAMATIOU, Yannis P.*; LOWE, Christopher G.; HOLLAND, Kim N.; University of Hawaii at Manoa; California State University Long Beach; University of Hawaii at Manoa: Variations in the response of gastric acid secretion during periods of fasting between shark species Elasmobranchs are the earliest known vertebrates to have developed an acid secreting stomach and also exhibit […]

MCELROY, EJ*; REILLY, SM; Ohio University; Ohio University: The evolutionary relationship between foraging mode and locomotor functional morphology in lizards Foraging mode has impacted many aspects of lizard biology. Locomotion is centrally important to foraging and therefore the morphology and function of the locomotor system should be a strong correlate of foraging mode phenotype. Here […]

MAHLER, L.*; KEARNEY, M.; Washington Univ., St. Louis; Field Museum of Natural History; Field Museum of Natural History: The Palatal Dentition in Squamate Reptiles: Morphology, Development, Attachment, and Replacement The palatal dentition in squamate reptiles is poorly known compared to the marginal dentition. We surveyed species of all squamate families for the presence of palatal […]

COLLAR, D.C.*; University of California, Davis: Testing the bass fisherman�s hypothesis: Does reaching an adaptive peak limit diversification of the feeding apparatus in Micropterus (Teleostei: Centrarchidae)? The potential for a lineage to diversify morphologically might be limited if it sits atop an adaptive peak. If the common ancestor of a lineage possesses structures and performance […]

HILL, R.I.; Univ. of California, Berkeley: Morphology and locomotor mimicry in ithomiine butterflies (Nymphalidae) Neotropical ithomiine butterflies (Nymphalidae) exhibit rampant convergent evolution of color patterns. It is not uncommon in lowland rainforest to find up to nine color patterns at a site, with several species from 2-5 genera exhibiting each pattern. This color pattern convergence […]

HOFFMAN, Eric A.*; GOODISMAN, Michael A. D.; University of Central Florida; Georgia Institute of Technology: Genomic analysis of caste differentiation in yellowjacket wasps Highly eusocial insects exhibit one of the most remarkable examples of polyphenism, the occurrence of discrete alternative phenotypes produced from a single genotype. Individuals belong to distinct castes (e.g. queens or workers) […]

SWEENEY, A.*; DES MARAIS, D.L.; BAN, A.; JOHNSEN, S.; Duke University; Duke University; Duke University; Duke University: Evolving Refractive Index: How Lens Protein Evolution Contributed to High-Resolution Squid Vision A lens with a graded refractive index is necessary for high-resolution animal vision. This graded refractive index is produced by a concentration gradient of a few […]
