Genitalia Malformations in Stramonita haemastoma (Gastropoda: Muricidae) from Atlantic and Mediterranean Coast

Journal of Aquaculture Research & Development, 2017
Stramonita haemastoma is a gonochoric marine gastropod. The examination of the genital tract has revealed the occurrence of malformations affecting the penis of males S. haemastoma, as for the females only aphallia was recorded. Investigations of the genital tract malformations were made in snails sampled monthly from Bizerta Channel (Northern Tunisia),

Chromatographic Characterization of Archaeological Molluskan Colorants via the Di-Mono Index and Ternary Diagram

Heritage, 2023
One of the main research questions regarding archaeological molluscan purple pigments and dyes is whether it is possible to determine which malacological species produced these colorants. For this determination of the zoological provenance of the pigment,

New Imposex Development Index (IDI) for Stramonita haemastoma (Mollusca: Muricidae): A Transplantation Experiment in the Brazilian Northeast [PDF]

Ecotoxicology and Environmental Contamination, 2007
A total of 600 Stramonita haemastoma (Mollusca: Muricidae) individuals, free of imposex, were transplanted into a marina with an intense ship flow. Thirty individuals were collected periodically until 210 days and analyzed according to RPLI (Relative Penis Length Index), RPSI (Relative Penis Size Index), IDI (Imposex Development Index, developed in ...

Imposex incidence in Stramonita haemastoma (Gastropoda: Muricidae) from the Mediterranean and Atlantic coast after Tributyltin global ban

Journal of Sea Research, 2018
Abstract The development of male genital tract by female gastropods, or imposex, can be caused by the tributyltin used in antifouling paints. A spatial survey of imposex in the gastropod Stramonita haemastoma was conducted across five Western Mediterranean and eleven North-Eastern Atlantic sites, in order to monitor the effectiveness of the ...

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

Brazilian Journal of Biology
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

Trophic Ecology of Loggerhead Turtles (Caretta caretta) in Southern Brazil: Insights From Stable Isotopes

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT This study aimed to investigate the trophic ecology of loggerhead turtles recorded stranded along the Paraná coast in southern Brazil. Carbon and nitrogen stable isotopes were analysed in muscle tissues from 20 loggerhead turtles and in 69 specimens representing 12 prey species (molluscs, crustaceans and teleost fishes).

Assessing the Continuous Impact of Tributyltin from Antifouling Paints in a Brazilian Mangrove Area Using Intersex in Littoraria angulifera (Lamarck, 1822) as Biomarker

International Journal of Oceanography, Volume 2013, Issue 1, 2013., 2013
Intersex is a sensitive biomarker of TBT exposure and effects in littorinid gastropods and described for the mangrove periwinkle Littoraria angulifera for the first time in this study. The objective was to describe the occurrence of intersex in L. angulifera, to propose the species as a sentinel organism to assess TBT contamination, and to characterize
