Non‐indigenous molluscs in the Eastern Mediterranean have distinct traits and cannot replace historic ecosystem functioning

Global Ecology and Biogeography, Volume 31, Issue 1, Page 89-102, January 2022., 2022
Abstract Aim A large body of ecological theory predicts that non‐indigenous species (NIS) are successful invaders if their niches overlap little with native taxa. Native–non‐indigenous trait dissimilarity, however, may also be observed if NIS have outcompeted ecologically similar native species. Discriminating these scenarios is essential for assessing

Phylogeography of Agathistoma (Turbinidae, Tegulinae) snails in tropical and southwestern Atlantic

Zoologica Scripta, Volume 51, Issue 1, Page 76-90, January 2022., 2022
Abstract The rocky intertidal gastropods Agathistoma viridulum and A. hotessierianum occur from the Caribbean to southern Brazil, with a gap in the equatorial region, giving them an anti‐tropical distribution. We used sequences from mitochondrial genes to elucidate the phylogeography of A. viridulum and A.

Non‐native species outperform natives in coastal marine ecosystems subjected to warming and freshening events

Global Ecology and Biogeography, Volume 30, Issue 8, Page 1698-1712, August 2021., 2021
Abstract Aims Contemporary climate change and biological invasions are two main drivers of biodiversity redistribution. Interactive effects between these drivers have been reported in a variety of studies, yet results are conflicting. Some studies find that contemporary climate change facilitates the spread and success of non‐native species, especially

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,

Characterization of the occupied shells by the hermit crab Clibanarius vittatus (Decapoda, Diogenidae) at Baixio Mirim tideflat, Guaratuba Bay, southern Brazil

Anais da Academia Brasileira de Ciências, 2010
A characterization of the occupied shells by the hermit crab Clibanarius vittatus was carried out. Hermit crabs were collected in the intertidal zone, during the low spring tide monthly from April 2005 to March 2006.

Imposex in endemic volutid from Northeast Brazil (Mollusca: Gastropoda)

Brazilian Archives of Biology and Technology, 2008
Imposex is characterized by the development of masculine sexual organs in neogastropod females. Almost 120 mollusk species are known to present imposex when exposed to organic tin compounds as tributyltin (TBT) and triphenyltin (TPT). These compounds are

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

Brazilian 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 ...

First record of the gastropod Stramonita haemastoma (Linnaeus, 1767) in the English Channel

BioInvasions Records, 2019
Here we report the first record of the red mouthed rock shell Stramonita haemastoma (Linnaeus, 1767) (Gastropoda, Muricidae) a predatory gastropod newly introduced to the English Channel. This species originally lives in the western Atlantic, eastern Pacific and Mediterranean Sea. Three specimens were collected on Pecten maximus at St-Martin-de-Bréhal,

Historical human activities reshape evolutionary trajectories across both native and introduced ranges

Ecology and Evolution, Volume 10, Issue 13, Page 6579-6592, July 2020., 2020
The same vectors that introduce species to new ranges could move them among native populations, but how human‐mediated dispersal impacts native ranges has been difficult to address because human‐mediated dispersal and natural dispersal can simultaneously shape patterns of gene flow.

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),
