Tributyltin (TBT) and other pollutants are present in Patagonia, associated with maritime traffic human activities. Cause–effect relationship between TBT imposex development females of marine gastropods is well documented. We tested whether the incidence pollution related to detectable shell-shape variations edible snail (Buccinanops globulosus). compared shell shape B. globulosus six contiguous sites on a gradient traffic, by using geometric morphometric analysis. Our results indicated that...
The rocky shore of Punta Este, Golfo Nuevo (Patagonia, Argentina), was sampled by means the standardized NaGISA (CoML) protocol, that aimed to generate biodiversity baseline data in six levels, from high intertidal 10 m depth. Based on generated data, we analysed benthic assemblage structure, species richness, mean abundance and distribution pattern invertebrate functional groups, typifying each subtidal level. is exposed extreme physical conditions higher than any other system studied, with...
High concentrations of metals are accumulated by edible marine resources, affecting human health. Marine gastropods have been commercially captured and consumed in Argentina for decades without official regulations or studies to guarantee their safety. In this study, (cadmium, aluminium, iron, zinc, copper lead) were analysed the first time Buccinanops globulosus, Adelomelon ancilla Trophon geversianus surrounding sediments. Taking into account maximum levels recommended national...
Abstract The superposition of male sexual characteristics in female marine gastropods (imposex) represents one the clearest ecological examples organotin-mediated endocrine disruption. Recent evidences suggest that signaling pathways mediated by members nuclear receptor superfamily, RXR and PPARγ, are involved development this pseudohermaphroditic condition. Here, we identified significant differences expression two caenogastropod species from Nuevo Gulf, Argentina, Buccinanops globulosus...
The gastropod Buccinanops globulosus is commonly used as a bioindicator of tributyltin (TBT) contamination due to its high imposex incidence in maritime traffic areas. aim this study was evaluate both oxidative stress B. at three sites with different activity, and Nuevo Gulf, Argentina. Oxidative parameters digestive glands, like superoxide dismutase (SOD) glutathione-S-transferase (GST) activities, reduced glutathione levels (GSH), damage lipids, estimated thiobarbituric acid reactive...
El objetivo de este trabajo fue estudiar parámetros reproductivos y desarrollo imposex en el caenogasterópodo Buccinanops globulosus que habita una zona portuaria alto tráfico marítimo con presencia contaminantes. Los resultados mostraron mayor incidencia hembras sin ovicápsulas ovicápsulas. Entre las imposex, del pene significativamente aquellas (3.4 mm) (1.5 mm). En B. comúnmente un solo juvenil eclosiona por cada cápsula, embargo, estudio se registraron capsulas múltiples embriones. Todos...
The marine gastropod Buccinanops globulosus is known to have high imposex incidence in areas moderately polluted by tributyltin (TBT). Acute toxicity was previously studied adults but no information about embryonic intracapsular development. To estimate the potential effects of organotin pollution on progeny B. globulosus, acute tests were conducted encapsulated and excapsulated pre-hatching embryos. lethal median concentration estimated for 96 h (LC50 h) embryos 196.70 µg TBTCl L−1, while...
