Ocean acidification (OA) can impair antioxidant responses in bivalves altering their capacity to cope with environmental changes. Here, we analyzed the effects of short-term OA exposure on an important commercial Patagonian scallop Zygochlamys patagonica (P.P. King, 1832), considering present pH variability at natural beds scallops and conditions. The were exposed three levels pH, (1) high pHT= 8.10 (mean annual sampling site), (2) medium 7.80 (minimum value recorded scallops’ bed close...
Ocean acidification (OA) is a global process decreasing seawater pH. It direct consequence of the increase in CO2 emissions due to human activities, with consequences for marine species and ecosystems. The effects long-term OA exposure (6 months) followed by 2 months depuration were analyzed. Mortality, shell growth, mass, adductor muscle mass and, gonadal condition indexes (CI) measured Patagonian scallop Zygochlamys patagonica, an important seafood Southwest Atlantic Ocean. scallops...
Hypoxia in freshwater ecosystems is spreading as a consequence of global change, including pollution and eutrophication. In the Patagonian Andes, decline precipitation causes reduced lake water volumes stagnant conditions that limit oxygen transport exacerbate hypoxia below upper mixed layer. We analyzed molecular biochemical response North bivalve Diplodon chilensis after 10 days experimental anoxia (< 0.2 mg O2 / L), (2 normoxia (9 L). Specifically, we investigated expression an...
Context Bivalve fishery represents an important socio-economic resource in Río Negro province, and Mytilus platensis is the main exploited species. Thus, biomonitoring trace metals this mussel particularly relevant for both environmental protection human consumption. Aim Anthropogenic pollution its impact on mussels were experimentally evaluated situ two coastline sites of northern Patagonia. Methods Trace metal concentrations quantified water a harbour area (Port San Antonio Este) reference...
Abstract Freshwater bivalves of the order Unionoida display an uncommon phenotypic plasticity with high interpopulation and intrapopulation morphological variability, which could be advantageous for coping habitat modifications. However, unionoids have suffered a marked population decline in different parts world last decades. A some populations South American long‐lived freshwater mussel Diplodon chilensis as consequence deterioration has recently been recorded. Ontogenetic allometry shape...
Markers of oxidative stress and biochemical composition were investigated in digestive gland gonad tissues the freshwater mussel Diplodon chilensis, as well morphometric variables relation to chronological age sex. Individual growth followed a von Bertalanffy model (VBGM). Superoxide dismutase activity, glutathione level damage proteins remain constant through life both tissues, whereas catalase glutathione-S-transferase activities lipid peroxidation decrease until 24–27 years age, fairly...
Abstract Water quality was monitored along an Andean river of global importance using the freshwater bivalve Diplodon chilensis as sentinel species. Bivalves were placed in cages at three sites (S1–3) Chimehuin River order to evaluate long‐term effects a trout hatchery (S2) and open dump sewage treatment plant nearby city (S3). samples bivalves collected 0, 3, 6, 9 12 months, from S3, S2 reference site upstream (S1), physicochemical parameters biological response caged studied.

Climate change is producing sea level rise and deoxygenation of the ocean, altering estuaries coastal areas. Changes in oxygen availability are expected to have consequences on physiological fitness intertidal species. In this work we analyze coping response stout razor clam (Tagelus plebeius (Lightfoot, 1786)) extreme environmental changes concentration. Their biochemical responses normoxia, hypoxia, hyperoxia transition at different (low–high) were measured through an situ transplant...

Through oxidative stress indicators, it is possible to quantify response organisms changes physical-chemical, and/or variables. Therefore,...
While the physical characteristics of sandy beaches play a significant role in shaping macrofaunal community features through morphodynamics, regional environmental factors may also account for deviations from expected patterns. Here, we assess concurrent effects local morphodynamic and variables, such as sea surface temperature (SST), salinity, chlorophyll-a (chl-a), on species richness abundance assemblages four located along estuarine gradient generated by Río de la Plata (RdlP)...
