BARAGONA, M.A.*; HAIG-LADEWIG, L.A.; WANG, S.Y.: Multiple Paternity in the Grass Shrimp Palaemonetes pugio Microsatellite markers were used to study the mating system of Palaemonetes pugio. Grass shrimp genomic libraries were screened for clones containing di- or trinucleotide repeats. Positive clones were sequenced and PCR primers were designed for clones containing more than five tandem […]

Barriga-Sosa, I.*; Arredondo-Figueroa, J. L.: Morphological and allozyme variation in Chirostoma grandocule Steindachner (Pisces:Atherinopsidae) from Lake P�tzcuaro, M�xico. We investigated the levels of population differentiation of the silverside fish species Chirostoma.grandocule Steindachner in Lake P�tzcuaro based on morphometric and allozyme data and relate such information to aspects of life history and changes in their natural […]

HOFFART, C.*; HILL, P.S.M.: Morphological and Molecular Phylogenetic Analyses of the Gryllotalpidae: What Came First, the Chirp or the Trill? The prairie mole cricket (Gryllotalpa major) is a burrowing insect native to the tallgrass prairies of the southern United States. The male produces a loud, long-range calling song at sunset in April and May by […]

WALSH, E.J.*; DE LA RIVA, V.: Molecular systematics of the Brachionidae (Phylum Rotifera) based on internal transcribed spacers (ITS) of the nuclear ribosomal gene complex. Rotifers play important roles in freshwater communities. Despite their ubiquity, little is known about their evolutionary relationships. From an ecological perspective brachionid rotifers have received considerable attention yet the most […]

CHAN, S.-M.; GU, P.-L.: Molecular characterization of a cDNA encoding for a shrimp Cellular Retinoic Acid/Retinol Binding Protein Members of the cellular retinoic acid binding protein (CRABP) family are small proteins involved in the metabolic pathways of retinoic acid (RA). Although there is report describing the cloning of a retinoic-X receptor, no report describes the […]

KRENZ, J.G.*; HASELKORN, T.S.; BRODIE, E.D., III; BRODIE, E.D., JR.; JANZEN, F.J.: Molecular Phylogeography of Common Garter Snakes (Thamnophis sirtalis) in Western North America Populations of the common garter snake (Thamnophis sirtalis) in western North America that are found in the same range as the coastally distributed rough-skinned newt (Taricha granulosa) display resistance to the […]

DAVIDSON, B.J.*; MOODY, W.; SWALLA, B.: Metamorphic Competence in the Urochordates: Cloning of a Potential Competence Factor Involved in EGF Signaling We are interested in elucidating the signals involved in coordinating urochordate post-larval development. Through suppressive PCR subtractions of staged Boltenia villosa larval and juvenile cDNAs, we have isolated transcripts differentially expressed during urochordate metamorphosis. […]

TASI, T.; MAURES, T.*; FUNKENSTEIN, B.; DUAN, C.: MOLECULAR CLONING AND EXPRESSION OF INSULIN-LIKE GROWTH FACTOR BINDING PROTEIN-2 IN THE GILTHEAD SEABREAM, SPARUS AURATA The insulin-like growth factors (IGFs) in extracellular fluids are bound to several high-affinity binding proteins (IGFBPs). The circulating IGF/IGFBP complexes prolong the half-lives of IGFs and buffer the acute hypoglycemic effects […]

KLOHR, S.D.*; EDER, S.; KRAJNIAK, K.G.: Localization and Effects of FMRFamide Related Peptides in the Earthworm Crop-Gizzard Previous studies have shown that the crop-gizzard of the earthworm, Lumbricus terrestris responds to FMRFamide. Recently, we used immunohistochemical techniques to see where FMRFamide is localized in these tissues and an isolated tissue assay to determine how they […]

MOORE, I.T.*; WINGFIELD, J.C.: Latitudinal gradient in sensitivity of the hypothalamic-pituitary-gonadal axis to gonadotropin-releasing hormone. Field investigations have revealed complex patterns of testosterone levels in vertebrates. Even in closely related taxa and within populations (especially birds) patterns of testosterone secretion may be dramatically different. The mechanisms underlying this variation in patterns remain unclear. At the […]
