Imposex in Stramonita haemastoma: a preliminary comparison between waterborne and dietborne exposure [PDF]

open access: hybridEcotoxicology and Environmental Contamination, 2014
00 adult individuals of the Stramonita haemastoma were collected from a pristine beach in Ceara State, Brazil. These organisms were transplanted into a marina with intense shipping activities and were fed weekly with oysters obtained from the same ...

Low abundance and skewed population structure of the whelk Stramonita haemastoma along the Israeli Mediterranean coast [PDF]

open access: bronzeMarine Ecology - Progress Series, 2001
Stramonita (=Thais) haemastoma (Kool, 1987), a relatively large predatory snail found in rocky littoral ecosystems, can attain densities of hundreds of individuals per m 2 in warm temperate coasts of the western Atlantic. It has also been reported as common along the Israeli Mediterranean coast; however our preliminary observations there suggested low ...

Locomotion of Stramonita haemastoma (Linnaeus) (Gastropoda, Muricidae) on a mixed shore of rocks and sand [PDF]

open access: diamondRevista Brasileira De Zoologia, 2001
Mixed shores of rocks and sand are appropriate systems for the study of limitations that the isolation of rocks may impose for gastropods that typically inhabit rocky shores. We marked 52 Stramonita haemastoma (Linnaeus, 1767) snails on a mixed shore and found that 34 of them moved between rocks one to four times during 15 surveys in a period of 72 ...

Unexpected mosaic distribution of two hybridizing sibling lineages in the teleplanically dispersing snail Stramonita haemastoma suggests unusual postglacial redistribution or cryptic invasion. [PDF]

open access: goldEcol Evol, 2017
AbstractMolecular approaches have proven efficient to identify cryptic lineages within single taxonomic entities. Sometimes these cryptic lineages maybe previously unreported or unknown invasive taxa. The genetic structure of the marine gastropodStramonita haemastomahas been examined in the Western Mediterranean and North‐Eastern Atlantic populations ...

Spatial-temporal distribution and recruitment of Stramonita haemastoma (Linnaeus, 1758) (Mollusca) on a sandstone bank in Ilhéus, Bahia, Brazil [PDF]

open access: goldBrazilian Journal of Biology, 2011
We examined aspects of the population ecology of the gastropod Stramonita haemastoma at Ilhéus, Bahia, Brazil. We collected monthly from October 2007 through September 2008 on a sandstone bank 1.5 km long, on which two points and two sampling levels were defined.

Stramonita haemastoma as a bioindicator for organotin contamination in coastal environments [PDF]

open access: greenMarine Environmental Research, 2007
Stramonita haemastoma was investigated as a suitable bioindicator of TBT and TPhT contamination in the tropical Atlantic Ocean by: 1. Imposex induction in healthy females after inoculation with TBT and TPhT in the laboratory; and 2. Determining incidence of imposex in S.

Organotin pollution at Arraial do Cabo, Rio de Janeiro State, Brazil: increasing levels after the TBT ban [PDF]

open access: yesBrazilian Journal of Oceanography, 2011
Imposex, an endocrine disruption phenomenon, is a biomarker of tributyltin (TBT) exposure in marine gastropod populations. The occurrence and intensity of the syndrome in populations of the neogastropod Stramonita haemastoma were ascertained at nine ...

Evolution of Duplicated Hox Gene Clusters in Land Snails and Slugs. [PDF]

open access: yesJ Exp Zool B Mol Dev Evol
Molluscs of the order Stylommatophora underwent an ancient genome duplication. We show that stylommatophoran snails and slugs have two broken and incomplete Hox gene clusters; HoxA generally has 9 genes, HoxB usually has 7 genes. After duplication of an ancestral 11‐gene Hox cluster, there was patchwork retention of duplicated genes.
