Phylogeny and Classification of Extant Gastropoda
网页In the last few years, however, something of a consensus has emerged about the major features of gastropod phylogeny, and a stable classification is now developing. For most of the twentieth century, gastropods were divided into three major groups (frequently referred to as “subclasses”): Prosobranchia, Opisthobranchia, and Pulmonata.
A Phylogenomic Backbone for Gastropod Molluscs - Oxford …
网页2022年6月29日 · Vetigastropoda is a key clade to elucidate both the phylogeny and the evolutionary history of Gastropoda, given 1) its hypothesized age between ca. 485 Ma (Wagner 2002) and ca. 420 Ma (Fryda et al. 2008), 2) its position in some phylotranscriptomic trees contradicting the monophyly of the Orthogastropoda (Zapata et al. 2014; Cunha and Giribet ...
A Phylogenomic Backbone for Gastropod Molluscs - PubMed
网页2022年10月12日 · Currently, gastropods are divided into six subclasses: Caenogastropoda, Heterobranchia, Neomphaliones, Neritimorpha, Patellogastropoda, and Vetigastropoda. Phylogenetic relationships among these taxa historically lack consensus, despite numerous efforts using morphological and molecular information.
The molecular phylogeny of Caenogastropoda (Mollusca, Gastropoda…
网页Although the monophyly of Caenogastropoda has been widely accepted, thier internal phylogenetic relationships remain unclear. In the present study, a total of 27 caenogastropods belonging to eight superfamilies were sequenced and used for phylogenetic reconstruction.
Phylogenomic analyses of deep gastropod relationships reject ...
网页2014年11月7日 · In this study, we address the evolution of Gastropoda and evaluate the relationships among and within major clades in this group by creating a comprehensive taxonomic dataset from 40 novel transcriptomes and 16 …
Neogastropod (Mollusca, Gastropoda) phylogeny: A step …
网页2022年6月29日 · The Neogastropoda (Mollusca, Gastropoda) encompass more than 15,000 described species of marine predators, including several model organisms in toxinology, embryology and physiology. However, their phylogenetic relationships remain mostly unresolved and their classification unstable.
Gastropoda: An Overview and Analysis | Phylogeny and Evolution …
网页This chapter presents an overview and analysis of the phylogeny and evolution of the molluscan class Gastropoda. It explains that Gastropoda is the largest molluscan class and it contains the greatest diversity of described marine species.
Gastropod phylogenetics: Progress, problems, and implications
网页If we can control the effects of homoplasy, then gastropods are an excellent “model” group for testing macroevolutionary hypotheses such as changing rates of evolution. Two obvious candidates are rates of morphologic evolution among basal neogastropods, and rates of molecular evolution within clades radiating after the K/T mass extinction.
Classification and Nomenclator of Gastropod Families
网页2005年1月1日 · A working classification attempts to reconcile recent advances in the phylogeny of the Gastropoda, using unranked clades above superfamilies, and the more traditional approach, using...
Global diversity of gastropods (Gastropoda; Mollusca) in freshwater
网页Molecular phylogeny of a circum-global, diverse gastropod superfamily (Cerithioidea: Mollusca: Caenogastropoda) pushing the deepest phylogenetic limits of mitochondrial LSU rDNA sequences. Molecular Phylogenetics and Evolution 22: 399–406.
