Abstract Ocean acidification is considered detrimental to marine calcifiers, but mounting contradictory evidence suggests a need revisit this concept. This systematic review and meta‐analysis aim critically re‐evaluate the prevailing paradigm of negative effects ocean on calcifiers. Based 5153 observations from 985 studies, many calcifiers (e.g., echinoderms, crustaceans, cephalopods) are found be tolerant near‐future (pH ≈ 7.8 by year 2100), coccolithophores, calcifying algae, corals appear sensitive. Calcifiers generally more sensitive at larval stage than adult stage. Over 70% in growth calcification non‐negative, implying acclimation capacity acidification. can mediated phenotypic plasticity physiological, mineralogical, structural, molecular adjustments), transgenerational plasticity, increased food availability, or species interactions. The results suggest that impacts less deleterious initially thought as their adaptability has been underestimated. Therefore, forthcoming era research, it advocated studying how organisms persist important they perish, future hypotheses experimental designs not constrained within effects.

Limitations of cross‐ and multigenerational plasticity for marine invertebrates faced with global climate change

Global Change Biology, Год журнала: 2019, Номер 26(1), С. 80 - 102

Abstract Although cross generation (CGP) and multigenerational (MGP) plasticity have been identified as mechanisms of acclimation to global change, the weight evidence indicates that parental conditioning over generations is not a panacea rescue stress sensitivity in offspring. For many species, there were no benefits conditioning. Even when improved performance was observed, this waned time within or across fitness declined. CGP MGP studies resilient species with tolerant genotypes wild populations selected family lines. Several bivalves possess favourable tolerance phenotypically plastic traits potentially associated genetic adaptation life habitats where they routinely experience temperature and/or acidification stress. These will be important help ‘climate proof’ shellfish ventures. Species are naturally those broad range environmental conditions good candidates provide insights into physiological molecular involved MGP.

As result, present stressors shock‐type exposure at rates much faster than projected scenarios.

Ocean acidification promotes broad transcriptomic responses in marine metazoans: a literature survey

Frontiers in Zoology, Год журнала: 2020, Номер 17(1)

Опубликована: Фев. 17, 2020

Abstract For nearly a decade, the metazoan-focused research community has explored impacts of ocean acidification (OA) on marine animals, noting that changes in chemistry can impact calcification, metabolism, acid-base regulation, stress response and behavior organisms hold high ecological economic value. Because OA interacts with several key physiological processes organisms, transcriptomics become widely-used method to characterize whole organism responses molecular level as well inform mechanisms explain phenotypes observed OA. In past there been notable rise studies examine transcriptomic metazoans, here we attempt summarize findings across these studies. We find vary dramatically their pH although common patterns are often observed, including shifts ion metabolic processes, calcification mechanisms. also see examining organismal multi-stressor context, reporting synergistic effects temperature. addition, is an increase use evolutionary potential adapt conditions future through population transgenerational experiments. Overall, literature reveals complex OA, which some will face more dramatic consequences than others. This have wide-reaching communities ecosystems whole.

The impact of environmental acidification on the microstructure and mechanical integrity of marine invertebrate skeletons

Abstract Ocean acidification (OA), from seawater uptake of anthropogenic CO2, has a suite negative effects on the ability marine invertebrates to produce and maintain their skeletons. Increased organism pCO2 causes hypercapnia, an energetically costly physiological stress. OA alters carbonate chemistry, limiting available form calcium (CaCO3) minerals used build The reduced saturation state CaCO3 also corrosion structures. Global change is accelerating coastal driven by land-run off (e.g. acid soil leachates, tannic acid). Building maintaining biomaterials in face changing climate will depend balance between calcification dissolution. Overall, response environmental acidification, many calcifiers less biomineral so have smaller body size. Studies skeleton development echinoderms molluscs across life stages show stunting effect OA. For corals, linear extension may be maintained, but at expense dense biomineral. Conventional metrics quantify growth need augmented characterisation changes structure mechanical integrity caused acidification.

Marine nano-ecotoxicology has emerged with the purpose to assess environmental risks associated engineered nanomaterials (ENMs) among contaminants of emerging concerns entering marine environment. ENMs' massive production and integration in everyday life applications, their peculiar physical chemical features, including high biological reactivity, have imposed a pressing need shed light on risk for humans Environmental safety assessment, known as ecosafety, thus become mandatory perspective develop more holistic exposure scenario understand effects. Here, we review current knowledge behavior impact ENMs which end up A focus titanium dioxide (n-TiO2) silver nanoparticles (AgNPs), metal-based massively used commercial products, polymeric NPs polystyrene (PS), largely adopted proxy nanoplastics, is made. eco-interactions molecules (bio)natural ones anthropogenic pollutants, forming eco- bio-coronas link uptake toxicity organisms are discussed. An ecologically based design strategy (eco-design) proposed support development new ENMs, those applications (e.g., nanoremediation), by balancing effectiveness no humans.

Acute environmental temperature variation affects brain protein expression, anxiety and explorative behaviour in adult zebrafish

Abstract This study investigated the effect of 4-d acute thermal treatments at 18 °C, 26 °C (control) and 34 on nervous system adult zebrafish ( Danio rerio ) using a multidisciplinary approach based behavioural tests brain proteomic analysis. The variations induced by treatment were five different tests, novel tank diving, light dark preference, social mirror biting, Y-Maze which are standard paradigms specifically tailored for to assess their anxiety-like behaviour, boldness, aggressiveness, explorative respectively. Proteomic data revealed that several proteins involved in energy metabolism, messenger RNA translation, protein synthesis, folding degradation, cytoskeleton organisation synaptic vesiculation regulated differently extreme temperatures. results showed behaviours increase compared those or whereas anxiety-related signalling pathways downregulated. Moreover, both affect exploratory behaviour appears not be modulated past experiences, suggesting impairment fish cognitive abilities. is continuation our previous work 21-d chronic same constant temperature level will enable comparison effects function zebrafish.
