Se denomina imposex a la aparición de caracteres sexuales secundarios en hembras de neogasterópodos producidos por laexposición a tributil-estaño (TBT). No existen hasta la fecha reportes de este fenómeno en el Cari...

Holoplanktonic gastropods (pteropods and heteropods) are major components of modern Indo–West Pacific (IWP) plankton, yet their fossil record in this region remains sparse. Expanding the spatial and temporal coverage o...

Pomacea canaliculata is a highly successful invasive snail that shapes freshwater communities in both native and invaded habitats. We studied its digenean parasites from three freshwater bodies in its native distribution...

Gastropoda, with approximately 80,000 living species, is the largest class of Mollusca. Among gastropods, apple snails (family Ampullariidae) are globally distributed in tropical and subtropical freshwater ecosystems and...

The importance of small-scale heterogeneity in local factors which overrides that of larger-scales factors, suggest that local factors play a major role in determining the richness and prevalence of larval digeneans in i...

Trochotomidae is a small but distinctive extinct family of pleurotomarioidean gastropods characterized by trochiform shells with an elliptical trema. Two new species of trochotomids are described from Pliensbachian depos...

The conquest of the terrestrial environment required numerous adaptations, although aerial respiration was what allowed animals to become completely independent of aquatic environments. Here, we analyze the specialized o...

In order to characterize the diet of Astropecten brasiliensis and Luidia ludwigi scotti, the stomach content of both starfish species was analyzed. Starfishes were sampled for two years off Puerto Quequén coast in the B...

The presence of evidence of depredation in ostracods valves from marine and freshwater environments of the central region of the republic Argentina are studied in this paper. In samples from intertidal environment (Puert...

The Bryn Gwyn (Chubut Province, Patagonia, Argentina) is a classic fossiliferous site, long recognised for its Cenozoic vertebrate record. However, its invertebrate content remains poorly documented. The Lower Miocene Ga...

The ichnogenus Lapispira Lange (originally recognized in the Hettangian of Germany) attained a wide geographic distribution, occurring mainly in Jurassic sediments. The ichnotaxon was recently re-described in Sinemurian-...

Trophic studies are key components in animal ecology and fisheries research. Although stomach samples are often obtained from fisheries, diet studies that consider the influence of fisheries on dietary results are still ...

This work aimed to evaluate the water quality of Soldati Lake (City of Buenos Aires, Argentina) through physicochemical and ecotoxicological studies. Two samplings were performed: one in summer 2023 (sites: S1 and S2) an...

Los gasterópodos Neritinidae de Puerto Rico presentan un ciclo de vida anfídromo y exhiben polimorfismo en los patrones de coloración de la concha. Se identificó que la oviposición aumenta río arriba conforme los i...
