Quinn, N.J.: Reef Check – Papua New Guinea’s participation in a global assessment of human effects on coral reefs Villagers in Papua New Guinea (PNG) have used coral reefs for thousands of years. Recent human development in PNG has altered the use of coral reefs. Today more reefs are fished commercially, used by tourist divers, […]

Green, A.K.*; Ward, D.: Dispersal of hemiparasitic mistletoe (Plicosepalus acaciae) by the Yellow-vented Bulbul (Pycnonoyus xanthopygos) among Acacia trees in Israel Infection by the mistletoe (Plicosepalus acaciae) may exacerbate the already low and infrequent recruitment of Acacia raddiana, A. tortilis, and A. gerrardii negevensis (70% of foraging attempts) only when fruits were abundant in the […]

SNYDER, M.J.*; ROSSI, S.: Alterations in Stress Proteins Correlate with Space Competition in Sessile Marine Invertebrates. Competition for space among sessile marine invertebrates, following larval settlement, can involve aggressive behaviors and the production of biologically active substances. These strategies have been widely studied in benthic cnidarians, for which the destructive nature of such responses to […]

Parham, J.F.*; Simison, W.B.; Kozak, K.H.; Feldman, C.R.: A reassessment of some recently described Chinese turtles Over the past 16 years, herpetologists described 13 new species of turtles. Most of these are based on specimens purchased from the pet trade. Herpetologists collected only two of these species, the rest have not been observed in the […]

Dworkin, I.M.*; Larsen, E.W: Temporal dynamics of the interaction between homothorax and Antennapedia in D. melanogaster The antenna to leg transformations induced by dominant alleles of Antennapedia (Antp) have become classic examples of homeotic transformation in D. melanogaster. It has recently been suggested that this transformation is due to Antp mediated repression of the homothorax […]

CORLEY, L.S.*; STRAND, M.R.: Regulation of Caste Fate in the Polyembryonic Wasp Copidosoma floridanum Striking morphological differentiation among individuals structures the complex societies found in insects such as termites, bees, and ants. Castes have also evolved in other insects such as aphids, thrips and polyembryonic wasps. Copidosoma floridanum is a polyembryonic parasitoid wasp that produces […]

DAVIS, G.K.*; JARAMILLO, C.A.; PATEL, N.H.: Pax group III genes and the evolution of insect pair-rule patterning We have investigated the expression of homologues of the Drosophila Pax group III (PgIII) genes paired (prd), gooseberry (gsb) and gooseberry-neuro (gsb-n) in short germ insects. During Drosophila embryogenesis, prd acts as one of several pair-rule genes to […]

FRIEDRICH, M.: Evolution of insect eye development: comparative and functional evidence for a conserved role of wingless in negatively controlling the spatial extent of retina differentiation Molecular genetic studies in model organisms like mouse and Drosophila have identified a number of genes, which appear to be expressed and required in similar ways during eye development. […]

Kettle, C. S.; Arthur, W.: Centipede embryology: conservation and change in early development within the Chilopoda and comparisons with other arthropods Centipedes provide a good opportunity to study the evolution of segmentation, because (a) different orders of centipedes have different numbers of segments and (b) within one order, Geophilomorpha, there is also intraspecific variation in […]

DAVIDSON, B.J.*; MOODY, W.; SWALLA, B.: Tunicate Out of Body Experiences: Extra-Somatic Cell Migration and Other Insights and Observations on Urochordate Metamorphosis We are investigating the morphological changes occurring during urochordate metamorphosis and the hormonal/transcriptional signals which coordinate this process. Initially, we have described a series of discrete morphological stages in the tunicate Boltenia villosa […]
