CLOUSE, R. M.*; GIRIBET, G.; Harvard University; Harvard University: The Systematics and Biogeography of the Stylocellidae, a Southeast Asian Family of Cyphophthalmi (Opiliones) Here we present our current understanding of the systematics of the Stylocellidae, a Southeast Asian family of the opilione suborder Cyphophthalmi. These animals are small (1-6 mm), cryptic, slow-moving arachnids that live […]

KIDD, Michael R.*; KOCHER, Thomas D.; University of New Hampshire; University of New Hampshire: Patterns of Ecological Diversification within Pseudotropheus tropheops, a Subgenus of Rock Dwelling Cichlid from Lake Malawi The haplochromine cichlids of Africa�s Great Lakes have become a celebrated example of adaptive radiation. Unfortunately, phylogenetic analysis of the Lake Malawi species flock has […]

TRIPP, Erin, A.; Duke University: Nothing happens once: systematics and parallel evolution in the species-rich genus Ruellia (Acanthaceae) The genus Ruellia (Acanthaceae) comprises ca. 300 species, is largely herbaceous, and is primarily tropical or subtropical in distribution. Ruellia is ecologically and evolutionarily interesting because of its diversity in floral and vegetative morphology, habit, and reproductive […]

MASSEY, S. E.*; CURTIS, N. E.; PIERCE, S. K.; Univ. of South Florida, Tampa; Univ. of South Florida, Tampa; Univ. of South Florida, Tampa: Identification of a retrovirus that may have a role in the life cycle and chloroplast symbiosis of kleptoplastic sea slugs. The annual life cycle of the kleptoplastic sea slug, Elysia chlorotica, […]

SPENCE, H.R.*; KNOWLTON, R.E.; MERCHANT, H.C.; Univ. of Massachusetts; George Washington Univ.; George Washington Univ.: A comparison of cryptic species of Alpheus (snapping shrimp) from North Carolina and Florida Differentiating cryptic species of snapping shrimp (Alpheidae), despite their ubiquity and acoustic fame, is fraught with misidentifications and ambiguity. Much of this confusion is due to […]

DEAN, M.N.*; AZIZI, E.; SUMMERS, A.P.; Univ. of California Irvine; Brown University; University of California Irvine: Uniform strain in broad muscles: A new twist on tendons Myofilament overlap determines tension generation in all vertebrate skeletal muscle. The range of muscle fiber strains used to generate a given movement (i.e., sarcomere lengths) is therefore linked to […]

FIELDS, P.A.*; STROTHERS, C.; Franklin and Marshall College, Lancaster, PA; Franklin and Marshall College, Lancaster, PA: Muscle-type lactate dehydrogenase of the Galapagos marine iguana, Amblyrhynchus cristatus, is adapted to high temperature. The Galapagos marine iguana, Amblyrhynchus cristatus, is unique among lizards in diving to forage. Air temperatures often exceed 40�C in the Galapagos; however, because […]

PRICE, E. R.*; GUGLIELMO, C. G.; University of Western Ontario; University of Western Ontario: Fatty Acid Composition of Muscle Phospholipids in Migratory Sparrows Migratory birds undergo numerous physiological changes in preparation for the high intensity endurance exercise associated with migration. The fatty acid composition of muscle membranes, particularly the n-6/to n-3 ratio of poly-unsaturated fatty […]

BATTIPROLU, P.K.; RODNICK, K.J.*; IDAHO STATE UNIV: Evidence for Sex Differences in Glucose-Mediated Cardiac Contractility in Rainbow Trout (Oncorhynchus mykiss) The heart of the rainbow trout is hypoxia-intolerant, may experience variations in oxygen availability and is omnivorous in its preference for metabolic fuels. However, the importance of exogenous glucose, oxygen and sex differences for contractile […]

KINSEY, S.T.*; DA SILVA, M.; PATHI, P.; LOCKE, B.R.; Univ. of North Carolina Wilmington; Florida State University; Florida State University; Florida State University: Diffusion limitation of aerobic metabolism in muscle fibers The net rate of metabolic processes in cells depends on the competition between the catalytic capacity of the system and the diffusive flow of […]
