Diversity of Indo-West Pacific Siphonaria (Mollusca: Gastropoda: Euthyneura).
Species of the limpet genus Siphonaria (Gastropoda: Euthyneura) are commonly found in the rocky intertidal, worldwide, except in the Arctic. In total, 205 species-group names are available and not permanently invalid. However, estimating the actual species diversity of Siphonaria has remained challenging, mainly because past authors have interpreted differently the variation of shell characters...
متن کاملMolecular phylogenetics of Caenogastropoda (Gastropoda: Mollusca).
Caenogastropoda is the dominant group of marine gastropods in terms of species numbers, diversity of habit and habitat and ecological importance. This paper reports the first comprehensive multi-gene phylogenetic study of the group. Data were collected from up to six genes comprising parts of 18S rRNA, 28S rRNA (five segments), 12S rRNA, cytochrome c oxidase subunit I, histone H3 and elongation...
متن کاملMolecular Evolution and Phylogeny of Actin Genes in Haliotis Species (Mollusca: Gastropoda)
Gene conversion and positive selection are often proposed as mechanisms for the evolution of biological molecules. Changes in sequence similarity have been used as evidence for gene conversion (Crain et al., 1987). Evidence for the evolution of the actin gene family by gene conversion in the echinoderms, Strongylocentrotus purpuratus and Pisaster ochraceus, came from amino acid and DNA sequence...
متن کاملMolecular phylogeny and evolution of the cone snails (Gastropoda, Conoidea).
We present a large-scale molecular phylogeny that includes 320 of the 761 recognized valid species of the cone snails (Conus), one of the most diverse groups of marine molluscs, based on three mitochondrial genes (COI, 16S rDNA and 12S rDNA). This is the first phylogeny of the taxon to employ concatenated sequences of several genes, and it includes more than twice as many species as the last pu...
متن کاملGiant embryos and hatchlings of Antarctic nudibranchs (Mollusca: Gastropoda: Heterobranchia)
of development up to ready-to-hatch juveniles 2.5 mm in length. Based on their morphology and development in egg masses maintained in the laboratory, the embryonic period for B. hodgsoni is estimated to be up to 10 years, and for D. kerguelenensis 13 months. Thus, B. hodgsoni has the largest egg capsules and probably the largest hatchlings of any mollusc. Chemical analyses of D. kerguelenensis ...
