STRUCK, T.H.; PURSCHKE, G.; University of Osnabr�ck, Germany; University of Osnabr�ck, Germany: Phylogenetic relationships of small and enigmatic polychaetes based on 18S-rDNA sequences The phylogeny of meiofaunal polychaetes based on morphological data is controversially discussed due to their great simplicity. These species often lack characters typical of larger polychaetes, such as parapodia and head appendages, […]

CONSTABLE, H.; MOOI, R.*; California Academy of Sciences, San Francisco; California Academy of Sciences, San Francisco: Phylogenetic analysis of echinothurioids, deep-sea echinoids with venomous spines Echinothurioids are strange, “regular” sea urchins having features indicative of a basal position in the phylogeny of extant echinoids. A few echinothurioids live on coral reefs, but the vast majority […]

AVDONINA, A.M.; Vladimir State Pedagogical University: Particular qualities of digestive system organization of Isohypsibius sattleri (Richters, 1902) (Tardigrada: Eutardigrada) with remarks about cuticle Many authors described the fine structure of various eutardigrade species (Dewel, Clark, 1973, Shaw, 1974, Greven, 1975, Dewel, Dewel, 1979, Dewel, Nelson, Dewel, 1993, Eibye-Jacobsen, 1996, 1997 and others). The subject of […]

A variety of genes have been identified which may be involved in sex determination […]

HACHTMAN., R.; RANCK, F.; ROSE, J.; RYAN, W.L.*; Kutztown University of Pennsylvania: Oxygen Measurement as an Indicator of Optimum Light Conditions for the Sea Anemone Aiptasia: Normal vs. Bleached Individuals The sea anemone, Aiptasia, is a nuisance for home aquarists, in part because of its ability to reproduce from fragments and in part due to […]

SANTINI, F.; University of Toronto: Osteology and phylogeny of the smooth pufferfishes (Tetraodontidae: Tetraodontiformes: Teleostei). The family Tetrodontidae (Tetraodontiformes, Teleostei) comprises over 120 species of mostly coral reef fishes, with some taxa found also in brackish waters. Commonly known as smooth pufferfishes, these morphologically very derived teleosts possess the smallest genome (in DNA content per […]
