LIUBICICH, Danielle M.*; SERANO, Julia M.; PATEL, Nipam H.; University of California, Berkeley; University of California, Berkeley; University of California, Berkeley: The role of Hox genes in crustacean appendage diversity Crustaceans display extraordinary diversity in appendage morphology and body regionalization. Although these animals display many unique morphological characteristics, they utilize patterning mechanisms conserved among all […]

CROTWELL, P.L.*; MABEE, P.M.; Univ. of South Dakota, Vermillion: Proximal-distal segmentation and evolution of the vertebrate skeleton Although anterior-posterior subdivision of the body axis is what is typically meant by �segmentation,� proximal-distal segmentation is a common occurrence in the development of the vertebrate skeleton. Fish fin rays and endoskeletal fin supports (radials) are segmented proximo-distally, […]

FR�BIUS, A.C.*; SCHWAB, R.L.; SEAVER, E.C.; University of Hawaii at Manoa; University of Hawaii at Manoa; University of Hawaii at Manoa: Expression of Hox and ParaHox genes during development of the polychaete annelid Capitella sp. I In recent years Hox genes have been isolated from most animal phyla. These genes are clustered in vertebrates and […]

HUGGINS, KA*; NAVARA, KJ; HILL, GE; MENDONCA, MT; Auburn University: Long Term Performance Detriment In Songbirds With Extensive Carotenoid-Based Plumage Coloration: Are Carotenoids Toxic? Although there is extensive literature addressing the beneficial effects of carotenoids as antioxidants and immune enhancers, there are also studies that indicate that high doses of carotenoids may actually have a […]

MENDON�A, M T*; WARD, C K; Auburn Univ: Latitudinal variation in stress responsiveness in anurans: preliminary evidence Tropical vertebrates generally exhibit a different suite of life history traits from their temperate counterparts. Additionally, there are physiological traits that also exhibit a latitudinal cline. For example, tropical birds and mammals have long been documented as having […]

BAZE, Monica*; HAYES, Jack P. ; WEBER, Lee A.; University of Nevada, Reno; University of Nevada, Reno; University of Nevada, Reno: Gene Expression of House Mice Acclimated to Chronic Hypoxia Chronic hypoxia is a significant physiological challenge to mammals in high altitude environments (2500 m or more). To accommodate the decrease in O2 partial pressure, […]

JOYNER-MATOS, J.*; CHAPMAN, L. J.; JULIAN, D.; Univ. of Florida, Gainesville; McGill Univ., Montreal; Univ. of Florida, Gainesville: Elevated dissolved oxygen level influences fingernail clam (Sphaerium sp.) stress protein expression and population distribution in a Ugandan papyrus swamp Abiotic factors can affect species distribution by stressing organisms to their physiological limits. In a population distributed […]

PETES, L.E.*; WEBB, M.A.H.; MENGE, B.A.; Oregon State Univ.; Bozeman Fish Technology Center; Oregon State Univ.: Differential accumulation of carotenoids in mussel gonadal tissue: a potential response to oxidative stress Field identification of mussel sex based on gonadal pigmentation is a common practice in marine ecology, based on the theory that males have white gonads, […]

Meeting Abstract 33.4  Jan. 5  Size Matters: Male mating tactics in a prosimian primate, slender loris Loris tardigradus KAR GUPTA, K*; KATTI, M; Arizona State University; California State University kaberi@asu.edu Nocturnal prosimian primates have been used as models to understand early evolution of primate social systems, but their social and mating systems are poorly understood. While simian […]

Meeting Abstract 33.2  Jan. 5  Plasticity in Brooding Time of a Species with Alternative Reproductive Modes OYARZUN, FX*; BRAVO, MJ; University of Washington; University of Washington foyarzun@u.washington.edu Species with alternative reproductive modes are rare, but serve as excellent models to study reproductive tradeoffs without phylogenetic confounding factors. Boccardia proboscidea (Polychaeta: Spionidae) has two main reproductive modes: some […]
