Ocean acidification represents a threat to marine species worldwide, and forecasting the ecological impacts of is high priority for science, management, policy. As research on topic expands at an exponential rate, comprehensive understanding variability in organisms' responses corresponding levels certainty necessary forecast effects. Here, we perform most meta-analysis date by synthesizing results 228 studies examining biological ocean acidification. The reveal decreased survival,...
Abstract. Macrophytes growing in shallow coastal zones characterised by intense metabolic activity have the capacity to modify pH within their canopy and beyond. We observed diel changes (5–12 m) seagrass (Posidonia oceanica) meadows spanning 0.06 units September 0.24 June. The carbonate system (pH, DIC, aragonite saturation state (ΩAr)) O2 displayed strong variability driven primary productivity, chemistry were related structural parameters of meadow, particular, leaf surface area available...
Abstract Invasion of ocean surface waters by anthropogenic CO 2 emitted to the atmosphere is expected reduce seawater pH 7.8 end this century compromising marine calcifiers. A broad range biological and mineralogical mechanisms allow calcifiers cope with acidification, however these are energetically demanding which affect other processes (trade-offs) important implications for resilience organisms against stressful conditions. Hence, food availability may play a critical role in determining...
Abstract Climate-related risks in Central and South America have received increased attention concern science policy, but an up-to-date comprehensive review synthesis of adaptation potential is currently missing. For this paper we evaluated over 200 peer-reviewed articles grey literature documents published since 2012. We found that climate change during the 21st century may increase risk to severe levels for following topical clusters: (a) Food insecurity; (b) Floods landslides; (c) Water...
Future ocean acidification (OA) will affect physiological traits of marine species, with calcifying species being particularly vulnerable. As OA entails high energy demands, during the rapid juvenile growth phase, food supply may play a key role in response organisms to OA. We experimentally evaluated modulating responses and biomineralization processes juveniles Chilean scallop, Argopecten purpuratus, that were exposed control (pH ~ 8.0) low pH 7.6) conditions using three treatments (high,...
Abstract Under future increased CO 2 concentrations, seagrasses are predicted to perform better as a result of photosynthesis, but the effects in carbon balance and growth unclear remain unexplored for early life stages such seedlings, which allow plant dispersal provide potential adaptation under changing environmental conditions. Furthermore, outcome concomitant biochemical changes plant-herbivore interactions has been poorly studied, yet may have important implications communities. In...
Abstract Coastal biota is exposed to continuous environmental variability as a consequence of natural and anthropogenic processes. Responding heterogeneous conditions requires the presence physiological strategies cope with environment. Ecosystems influenced by upwelling endure naturally cold, acidic hypoxic conditions, nevertheless they sustain major fisheries worldwide. This suggests that species inhabiting habitats possess adaptations handle high variability. Here, we assessed impact main...

Ocean acidification and hypoxic events are an increasing worldwide problem, but the synergetic effects of these factors seldom explored. However, this occurrence stressors is prevalent. The coastline Chile not only suffers from coastal hypoxia cold, oxygen-poor waters in upwelling also supersaturated CO2, a study site to explore combined effect ocean hypoxia. We experimentally evaluated metabolic response different invertebrate species (2 anthozoans, 9 molluscs, 4 crustaceans, 2 echinoderms)...
Penguins dominate the Antarctic avifauna. As key animals in ecosystem, they are monitored to evaluate ecological status of this pristine and remote region specifically, have been used as effective bioindicators suitable for long-term monitoring metals environment. However, studies about role emblematic organism could play recycling trace (TMs) ecosystem very limited. In study we evaluate, using peer review research articles already published our own findings, distribution (i.e., Ca, Fe, Al,...
The ocean off south-central Chile is subject to seasonal upwelling whose intensity mainly controlled by the latitudinal migration of southeast Pacific subtropical anticyclone. During austral spring and summer, mean flow equatorward favoring coastal upwelling, but periods strong southerly winds are intermixed with relaxed southerlies or weak northerly (downwelling favorable). This sub-seasonal, high-frequency variability results in pronounced changes oceanographic conditions air-sea heat gas...
Along the west coast of South America, from tropical zone to Patagonian waters, there is a significant latitudinal gradient in seawater temperature, salinity and carbonate chemistry. These physical–chemical changes induce morphological physiological responses calcifying organisms, which may alter their energy budget calcification processes. In this study, we study organism maintenance (i.e. metabolic rate) mineralogical composition shell juvenile marine snails Concholepas concholepas...

Changes in phenotypic traits, such as mollusc shells, are indicative of variations selective pressure along environmental gradients. Recently, increased sea surface temperature (SST) and ocean acidification (OA) due to levels carbon dioxide the seawater have been described agents that may affect biological processes underlying shell formation calcifying marine organisms. The benthic snail Concholepas concholepas (Muricidae) is widely distributed Chilean coast, so naturally exposed a strong...
