ZANOL, J.; FAUCHALD, K.; George Washington Univ. ; NMNH, Smithsonian Institution: Looking for more morphological information, a study of morphological characters in Eunicidae (Eunicida, Polychaeta, Annelida) One current problem in morphological phylogenetic studies of Polychaeta is the lack of knowledge about variability of diagnosing characters which makes the establishment of accurate primary hypotheses of homology […]

FERRIER, D.E.K.; Univ. of Oxford: Homeobox gene clusters in polychaete annelids. Genes of the Antp-superclass (including Hox, ParaHox and NK genes) are key regulators of development across the animal kingdom. A distinctive feature of these genes is that they tend to be arranged into clusters in the genome. This is typified by the famous Hox […]

NORENBURG, J.L.; THOLLESSON, M.; Natl. Mus. Nat. Hist., Washington DC; Uppsala Univ., Sweden: Diversification in the phylum Nemertea in light of a molecular phylogeny. A recent molecular phylogeny of Nemertea, based on Bayesian analysis of partial sequence data from four genes for 55 species-level taxa, proposed three new higher-level clades and resolution for several contested […]

GRAY, E.M.; BRADLEY, T.J.; Univ. of California, Irvine; Univ. of California, Irvine: Water Balance in two Tropical Mosquitoes, Anopheles gambiae and An. arabiensis Anopheles arabiensis and its sister species An. gambiae occupy distinct ranges in the African Sub-Saharan region: the former is found in more arid habitats than the latter. Small insects face a high […]

PINSHOW, Berry; Ben-Gurion University of the Negev: Plasma volume maintenance during long distance flight in birds vs. plasma volume maintenance in desert mammals: different origins for analogous traits Both mammals and birds defend plasma volume under stressful, dehydrating environmental conditions. In mammals, plasma volume maintenance has been studied in a variety of desert species and […]

WALSH, E.J.*; HOWARD, S.; BONILLA, L.; SCHROEDER, T.; Univ. of Texas at El Paso; Univ. of Texas at El Paso; Univ. of Texas at El Paso; Academy of Natural Sciences, Philadelphia: Patterns of diapause and sexual reproduction of Hexarthra (Rotifera) in temporary aquatic habitats of the Chihuahuan desert (HuecoTanks State Historic Site) Aquatic species inhabiting […]

POUCHKINA-STANTCHEVA, N.; TUNNACLIFFE, A.; Institute of Biotechnology, University of Cambridge, Cambridge, CB2 1QT, UK; Institute of Biotechnology, University of Cambridge, Cambridge, CB2 1QT, UK: Molecular studies of anhydrobiosis in bdelloid rotifers Bdelloid rotifers are renowned for their ability to survive extreme desiccation. Generally, onset of anhydrobiosis in Bdelloidea is characterised by reduced metabolism, arrested development […]

WILLIAMS, J.B.*; RUEHL, N. C. ; LEE, R. E.; Miami University, Oxford, Ohio; Miami University, Oxford, Ohio; Miami University, Oxford, Ohio: Links between cold hardiness and desiccation resistance in an overwintering insect To investigate possible links between cold-hardiness and desiccation resistance in insects, we examined changes in seasonal parameters associated with these phenomena in overwintering […]

GEFEN, E.; Univ. of Nevada, Las Vegas: Interspecific differences in water relations of scorpions: a new perspective Scorpions are thought to follow the water permeability:habitat relationship. Similarly, while scorpions are generally considered as poor osmoregulators the osmoregulatory capacities of the xeric buthid Parabuthus villosus were viewed as a useful adaptation to its xeric distribution. However, […]
