Evolutionary history of regeneration in crinoids (Echinodermata).
The fossil record indicates that crinoids have exhibited remarkable regenerative abilities since their origin in the Ordovician, abilities that they likely inherited from stem-group echinoderms. Regeneration in extant and fossil crinoids is recognized by abrupt differences in the size of abutting plates, aberrant branching patterns, and discontinuities in carbon isotopes. While recovery is comm...
متن کاملPCB exposure and regeneration in crinoids (Echinodermata)
Echinoderm regeneration provides a convenient and tractable test to monitor the effects of persistent micropollutants on the developmental physiology of marine animals. Regeneration involves crucial and sensitive biological processes (cell proliferation, morphogenesis, differentiation, tissue renewal) that make it an ideal tool to assess micropollutants at the tissue and cellular level. Our res...
متن کاملA revision of the genus Atelecrinus PH Carpenter (Echinodermata: Crinoidea).
The unusual bathyal comatulid crinoid genus Atelecrinus is widespread in the Atlantic and tropical Pacific Oceans and currently includes three recognized species. A re-assessment based on examination of new and existing specimens requires establishment of two new genera and five new species, and returns three junior synonyms to species-level status. Paratelecrinus is erected to accommodate Atel...
متن کاملCircumpolar dataset of sequenced specimens of Promachocrinus kerguelensis (Echinodermata, Crinoidea)
This circumpolar dataset of the comatulid (Echinodermata: Crinoidea) Promachocrinus kerguelensis (Carpenter, 1888) from the Southern Ocean, documents biodiversity associated with the specimens sequenced in Hemery et al. (2012). The aim of Hemery et al. (2012) paper was to use phylogeographic and phylogenetic tools to assess the genetic diversity, demographic history and evolutionary relationshi...
متن کاملNew Hyocrinid Crinoids (Echinodermata) from Submersible Investigations in the Pacific Ocean
A few specimens belonging to the deep-sea family Hyocrinidae (stalked Crinoidea, Echinodermata) collected by submersible in the eastern and western Pacific Ocean are described. Laubierierinus pentagonalis, n. genus, n. sp., from the North Fiji Rise is the first discovery of a hyocrinid crinoid with a pentaradially symmetrical stalk. Hyocrinus biscoitoi, n. sp., from the East Pacific Rise attain...
