Environmental and climate changes have placed increasing pressure on the resilience of marine ecosystems. In addition to these transformations, coastal environments are also affected by anthropogenic stressors, such as metal contamination. Bivalves play a crucial ecological role in estuarine This study aimed evaluate effects CO 2 -induced acidification, warming, mixed metals contamination mangrove mussel Mytella charruana . We evaluated DNA damage (strand breaks), lipid peroxidation (LPO) levels, reduced glutathione (GSH) content, well enzymatic activities S-transferase (GST) peroxidase (GPx) gills digestive glands. Additionally, neurotoxicity was assessed muscle tissues through acetylcholinesterase (AChE) activity. Laboratory experiments were conducted using sediments spiked with (Cu, Pb, Zn, Hg), alongside control group (non-spiked sediments), combining three pH levels (7.5, 7.1, 6.7) two temperatures (25 27°C). Five mussels per treatment (four replicates) exposed for 96 h. Two pools organisms each separated replicate ( n = 8) their gills, glands, muscles dissected biochemical biomarkers analyses. Temperature increase primary factors modulating antioxidant responses AChE activity muscle. However, when combined stressors integrity LPO. Acidification alone showed no effect any biomarker analyzed. Higher IBR values indicated exposure, even at concentrations below individual safety levels. Here, we provide insights from short-term experiment complex interactions between predicted scenarios, which change influenced associated mixture sediments. These findings contribute understanding organismal scenarios change, particularly environments.

A paradise for Maldane sarsi antarctica: preliminary characterization of the marine soft-bottom fauna of False Bay (Livingston Island, South Shetland Islands, Antarctica)

Abstract Soft-bottom areas are among the least explored ecosystems in Antarctica. To improve our understanding of these environments, we performed a preliminary assessment marine macrobenthic fauna False Bay, Livingston Island, near Huntress Glacier (South Shetland Islands, Antarctica). Fourteen Van Veen grabs (0.018 m 2 area) were deployed at two stations within bay depths 174–210 m. The samples provided values up to 159 556 individuals -2 15 major taxonomic groups. Annelida Polychaeta was predominant (~93%), followed by Ophiuroidea and Bivalvia external station Amphipoda internal site. Maldanid polychaetes, particularly Maldane sarsi antarctica , constituted 84.62–90.74% samples. Total biomass 6673.25 grams wet weight per square metre, mainly from Ascidiacea, Polychaeta, Holothuroidea Ophiuroidea. Approximately 12% macrofauna inhabited sediment (epifauna), while 88% lived into sediments (infauna). Regarding feeding modes, specimens detritivores (77.91–82.71%), suspension-feeders (7.59–13.37%) and, infrequently, predators (4.07–5.07%) grazers (4.63–4.65%). According compilation occurrence records Southern Ocean, M. has circum-Antarctic distribution. Furthermore, population this species Bay appears be stable undisturbed with normal distribution size structure, higher proportion intermediate sizes (2.85–4.26 cm). This study provides for first time detailed descriptions soft bottoms representing effort monitor ecological shifts critically important understudied region, which is experiencing rapid environmental changes Antarctic ecosystems.
