Biogeography and genetic diversity of the atlantid heteropods
The atlantid heteropods are regularly encountered, but rarely studied marine planktonic gastropods. Relying on a small (<14 mm), delicate aragonite shell and living in the upper ocean means that, in common with pteropods, atlantids are likely to be affected by imminent ocean changes. Variable shell morphology and widespread distributions indicate that the family is more diverse than the 23 curr...
متن کاملTime-calibrated molecular phylogeny of pteropods
Pteropods are a widespread group of holoplanktonic gastropod molluscs and are uniquely suitable for study of long-term evolutionary processes in the open ocean because they are the only living metazoan plankton with a good fossil record. Pteropods have been proposed as bioindicators to monitor the impacts of ocean acidification and in consequence have attracted considerable research interest, h...
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 کاملAtlantid Heteropods as Living Substrata for Eggs of Halobates sericeus (Heteroptera: Gerridae)
Atlantid heteropods are collected occasionally in Hawaiian waters with yellow, narrowly elliptical objects attached to their shells. Examination of 139 of these objects from 72 atlantids showed that they consisted of an outer, clear capsule whose contents were usually yellow, although 16 were empty and four contained brown insects at an advanced stage of development. The latter were identified ...
متن کاملAtlanta ariejansseni, a new species of shelled heteropod from the Southern Subtropical Convergence Zone (Gastropoda, Pterotracheoidea)
The Atlantidae (shelled heteropods) is a family of microscopic aragonite shelled holoplanktonic gastropods with a wide biogeographical distribution in tropical, sub-tropical and temperate waters. The aragonite shell and surface ocean habitat of the atlantids makes them particularly susceptible to ocean acidification and ocean warming, and atlantids are likely to be useful indicators of these ch...
