Accumulation and biotransformation dynamics of the neurotoxic complex, saxitoxin, in different life stages of Ostrea chilensis
Autor: Paola A. Villanueva, Gemita Pizarro, C. J. Segura, Alejandro Ortiz, Jorge M. Navarro
Publikováno v: Marine Environmental Research. 144:240-245
The neurotoxic complex saxitoxin, is a group of marine toxins that historically has significantly impacted human health and the ability to utilize marine resources. A steady increase in the distribution and intensity of Alexandrium catenella blooms i

Temporal changes in environmental conditions of a mid-latitude estuary (southern Chile) and its influences in the cellular response of the euryhaline anemone Anthopleura hermaphroditica

Publikováno v: Ecological Indicators. 88:169-180
The cellular response of the estuarine anemone Anthopleura hermaphroditica was assessed during a tidal cycle (low tide at noon) and compared between organisms acclimated to summer and winter environmental conditions (UV-B and PAR levels, salinity and

The influence of season and the tidal cycle on division of labour by the radula during feeding in the estuarine brooding gastropod Crepipatella dilatata (Calyptraeidae)
Autor: R. J. Thompson, V.M. Cubillos, C. J. Segura, J.A. Montory, L. P. Salas-Yanquin, Oscar R. Chaparro
Publikováno v: Helgoland Marine Research, Vol 72, Iss 1, Pp 1-11 (2018)
The brooding gastropod Crepipatella dilatata can feed by scraping the substrate with the radula and by suspension-feeding, which also requires use of the radula. There is a “division of labour” for the radula among three discrete tasks associated

Brooding strategy in fluctuating salinity environments: oxygen availability in the pallial cavity and metabolic stress in females and offspring in the Chilean oyster Ostrea chilensis
Autor: Oscar R. Chaparro, Jan A. Pechenik, C. J. Segura, V.M. Cubillos, Casey M. Diederich, J.A. Montory
Publikováno v: Journal of Comparative Physiology B. 185:659-668
Organisms that encounter stressful situations in nature often cope using behavioral (e.g., avoidance) or physiological tactics. In sessile mollusks, the only available behavioral option in dealing with salinity stress is to “clam up”, isolating t

At reduced salinities, brooding females of some gastropods and bivalves may isolate their mantle cavities from the environment for several days, maintaining internal osmotic concentration but causing severe declines in dissolved oxygen and pH, and in

Embryonic brooding in Crepipatella fecunda: Implications for processes related to maternal feeding
Autor: Maria Loreto Mardones, Oscar R. Chaparro, Sebastián Osores, C. J. Segura, Jan A. Pechenik
Publikováno v: Journal of Experimental Marine Biology and Ecology. 443:141-146
Females of the calyptraeid gastropod Crepipatella fecunda enclose their fertilized eggs in thin-walled egg capsules. They then brood these capsules for at least several weeks in the mantle cavity, near the gills. Such brooding has the potential to ob

We established the role of the pallial filter in the suspension-feeding slipper limpet Crepipatella fecunda (Gastropoda, Calyptraeidae), which inhabits coastal areas of southern Chile characterised by sediment resuspension resulting from tidal forces

Isolation-hypoxia and re-oxygenation of the pallial cavity of female Crepipatella dilatata during estuarine salinity changes requires increased glyoxylase activity and antioxidant metabolism to avoid oxidative damage to female tissues and developing embryos

Publikováno v: Marine environmental research. 119
The estuarine slipper limpet Crepipatella dilatata is a gastropod that can survive prolonged periods of low salinities (< 24 PSU) caused by tidal changes and/or prolonged periods of rain. During low salinity events, C. dilatata can isolate its body f

Marine larvae that experience some sub-lethal stresses can show effects from those stresses after metamorphosis, even when they seem to recover from those stresses before metamorphosis. In this study we investigated the short and long-term effects of
