Among � individual variation in energetic traits can have several fitness consequences. For example, increased energy […]

JAMES, LN*; HAHN, DA; University of Florida; University of Florida: Adult starvation reveals critical feeding threshold for reproduction in the flesh fly, Sarcophaga crassipalpis. The quality, quantity, and temporal availability of nutritional resources acquired during adult feeding have long been recognized as important factors influencing insect reproduction. However, numerous insects carry significant larvally derived nutritional […]

VON DASSOW, Y.J.; Univ. of California, Riverside: Abundance, diversity, and paleoecology of Pleistocene encrusting organisms The Pleistocene marine invertebrate fossil record of Southern California includes hundreds of mollusc species, which have been analyzed with regard to taxonomy, biogeography, and a number of other factors. However, the epibionts on their shells have been largely overlooked, despite […]

MYER, Bonnie L.*; BURGGREN, Warren ; University of North Texas: ALLOMETRY AND SCALING OF METABOLIC RATE OF DEVELOPING SILKWORMS, BOMBYX MORI Allometry purportedly determines physiological rates in developing as well as adult animals. Yet, the tissues and organs of developing animals must switch from hyperplastic differentiation to hypertrophic growth, and allometric principles may not apply […]

BOUZAIENE, M.*; ANGERS, A.; ANCTIL, M.; Universit� de Montr�al, Canada: A retinoic acid-like receptor in interstitial cells of two colonial anthozoans (Cnidaria) Retinoic acid is known to induce vertebrate stem cells to differentiate into a variety of cell types, including neurons. Although retinoic acid was reported to affect morphogenetic pattern specification in a cnidarian (the […]

MONETTE, M.Y.*; MCCORMICK, S.D.; Univ. of Mass., Amherst; USGS, Conte Anadromous Fish Research Center: A comparison of responses of Atlantic salmon parr and smolts to acid/aluminum exposure; why are smolts more sensitive? Acid rain coupled with resulting increased aluminum (Al) is a potential cause of Atlantic salmon decline in many North American rivers. Smolts appear […]

ALBERS, Melissa A*; BRADLEY, Timothy J; University of California, Irvine; University of California, Irvine: A Phylogenetic Analysis of the Evolution of Saline-Tolerance in Mosquito Larvae Saline-tolerance has evolved in mosquito larvae several times in various genera. The Ochlerotatus genus is of interest because there are both freshwater and saline-tolerant forms within this group and both […]

WALKER, JA; Univ. Southern Maine: A General Model of Functional Constraints on Phenotypic Evolution A general model of the functional constraints on the rate and direction of phenotypic evolution is developed using Arnold�s decomposition of the multivariate breeder�s equation. The important feature of the model is the F matrix of functional performance coefficients. The structure […]

Meeting Abstract P1.14  Jan. 4  White exudate of the West Indian topsnail, Cittarium pica (Vetigastropoda: Trochidae) HICKMAN, Carole S; COATES, Kathryn A*; Univ. of California, Berkeley; Bda Dept. Cons. Services kcoates@transact.bm Fluid exudates in marine mollusks are best known from taxa that lack shells; extensively studied compounds are the “inks” from octopus, cuttlefish, and squid. Their clouds […]
