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(More)
We present a new classification for the genus Conus sensu lato (family Conidae), based on molecular phylogenetic analyses of 329 species. This classification departs from both the traditional classification in only one genus and from a recently proposed shell- and radula-based classification scheme that separates members of this group into five families and(More)
A B S T R A C T In analyzing not-negation variation in English it becomes clear that specific strategies are used for prosodic emphasis and reduction of not in different social situations , and that contraction strategies vary independently of prosodic reduction. This article focuses on the factors influencing contraction strategies that are clearly dialect(More)
