YU, J-K; HOLLAND, L.Z.; HOLLAND, N.D.: Developmental expression of AmphiFoxD3, an amphioxus gene in the FoxD subfamily: insight into the evolutionary origin of vertebrate neural crest Neural crest is unique to vertebrates. Embryologically, neural crest derives from the edges of the neural plate and adjacent non-neural ectoderm, and undergoes an epithelial/mesenchymal transition to become a […]

BABBITT, C.C.*; PATEL, N.H.: Developmental Systematics: Correlation Between Ontogeny and Phylogeny in the Malacostraca (Crustacea) Although events in early development have long been used as defining characters for taxonomic groups, the phylogenetic signal of different developmental processes at different taxonomic levels has never been rigorously tested. The challenge has been to define distinct processes during […]

SECOR, S.M.*; NAGY, T.R.: Determination of lean, fat, and ash mass of snakes using dual-energy X-ray absorptiometry (DXA) Non-invasive measures of body composition (lean and fat mass, and bone mineral content) are crucial for studies in energetics, reproduction, and the regulation of body energy and mineral stores. Unfortunately, previous attempts to non-invasively determine body composition […]

FAULKNER, A.C.; SECOR, S.M.: Determinants of post-feeding response of the toad Bufo marinus Feeding stimulates an increase in metabolic rate and the summation of the energy expended on the ingestion, digestion, absorption, and assimilation of a meal is termed specific dynamic action (SDA). Previously, studies documented the effects of one or two of the following […]

CHARDON, Michel; PARMENTIER, Eric; VANDEWALLE, Pierre; DIOGO, Rui: Derived State of Weberian Characters in Loricarioids and Amphiliids Modifications of the Weberian apparatus are exceptional. The pars inferior of the labyrinths and anterior Weberian ossicles are transformed in loricarioids and amphiliids only (Chardon, 1967; Jenkins, 1979: electron microscopy; Coburn and Grubach, 1997: development; de Pinna, 1998: […]

REYNOLDS, J.A.*; HAND, S.C.: Depression of aerobic metabolism during diapause: insights from mitochondria of Artemia franciscana embryos In response to cues that signify onset of winter, female brine shrimp, A. franciscana, switch from ovoviviparous reproduction to oviparous production of encysted embryos that enter diapause. Diapause is a pre-programmed state of developmental arrest that is often […]

RIPLEY, B.J.; VERGARA, L.V.; TORRES, J.D.; HOLTZ, J.; SIMOVICH, M.A.: Cyst Size in Relation to Female Size in the San Diego Fairy Shrimp Branchinecta sandiegonensis In many organisms, larger females have larger offspring. Large offspring may have better survival, increasing fitness for these large females. The reproductive strategies of ephemeral pond crustaceans such as fairy […]

WHEATLY, M.G.*; GAO, Y.: Crayfish Plasma Membrane Ca ATPase: Characterization, Expression and Evolution. The crayfish molting cycle is used to study regulation of expression for Plasma Membrane Ca ATPase (PMCA). As in vertebrates PMCA is encoded by a family of 4 genes (PMCA 1-4). Expression was examined in an epithelium that transports Ca (gill) versus […]

HUDSON, H.A.*; HOM, J.R.; FIESS, J.C.; KATO, C.; YANCEY, P.H.: Corelations of hypotaurine and thiotaurine contents with sulfide metabolism in gills of vesicomyid bivalves from different cold seeps Most marine invertebrates use organic solutes such as taurine, glycine, and betaine as cell osmolytes. But recent studies show that deep-sea, hydrothermal-vent, and cold-seep animals have different […]

HELMUTH, Brian; DRYDEN, Colette; GARDNER, Kristi: Coral Reef Studies in the Classroom: Integration of Research with K-12 Education In November 2000, researchers from the University of South Carolina and the Louisiana Universities Marine Consortium studied the effects of reef hydrodynamics on coral physiology using the Aquarius habitat located near Key Largo, Florida. Specifically, we investigated […]
