Anthropogenic climate change is a significant driver of in marine ecosystems globally. To improve mechanistic understanding the impact climate-related stressors, experimental work on organisms has intensified recent decades. A previous synthesis paper published nearly decade ago established that Marine Climate Change Experiments (MCCEs) from 2000–2009 were primarily laboratory-based and focused single stressors individual focal temperate species. Using consistent methodology, we compared analysis to experiments following (i.e. 2010–2019) assess trends MCCEs determine what extent knowledge gaps research priorities have been addressed. The search returned 854 papers, vs. 110 2000s, indicating considerable intensification effort output. We found again species studies most common, particularly with benthic invertebrates as model organisms, comprised over 90% all studies. However, multiple stressor increased substantially, where tests for interaction effects between ocean acidification (i.e., p CO 2 ) warming common. Furthermore, wider range studied more community-level conducted 2010s 2000s. In addition, behavioral responses, transgenerational effects, genetic adaptation extreme climatic events markedly. These advances undoubtedly improved how will affect communities they underpin. Going forward, biases type distribution should be addressed enhance general responses environmental change. Similarly, manipulate greater number non-climate factors increase target realism. Finally, possible, further combined contextualized field-based observations better reflect complexity yield representative

Ocean acidification alters foraging behaviour in Dungeness crab through impairment of the olfactory pathway

Global Change Biology, Год журнала: 2023, Номер 29(14), С. 4126 - 4139

Crustacean olfaction is fundamental to most aspects of living and communicating in aquatic environments more broadly, for individual- population-level success. Accelerated ocean acidification from elevated CO2 threatens the ability crabs detect respond important olfactory-related cues. Here, we demonstrate that ecologically economically Dungeness crab (Metacarcinus magister) exhibits reduced antennular flicking responses a food cue when exposed near-future levels, adding growing body evidence impaired behaviour. Underlying this altered behaviour, find have lower olfactory nerve sensitivities (twofold reduction activity) response . This suggests levels will impact threshold detection by crabs. We also show sensitivity accompanied decrease sensory neuron (OSN) expression principal chemosensory receptor protein, ionotropic 25a (IR25a) which odorant coding signalling cascades. The OSNs exhibit morphological changes form decreased surface areas their somata. study provides first effects high at multiple biological organization marine crabs, linking physiological cellular with whole animal behavioural responses.

Effects of ocean acidification and ocean warming on the behavior and physiology of a subarctic, intertidal grazer

The global ocean is expected to both acidify and warm concurrently; thus, multiple-stressor manipulative experimentation an emergent area of study that ultimately aims examine the individual interactive effects these factors on marine organisms. We characterized physiological responses acidification warming intertidal grazer Lottia scutum , examined how change variables influenced predator-prey dynamics with Evasterias troschelii, a key sea star predator. Specifically, we conducted laboratory experiment where exposed limpets factorial combinations temperature (11 15°C) pH (7.6 8.0), measured thermal tolerance, metabolic rate, cortisol concentrations, behavioral found (OW) decreased critical maxima (CT max ) increased levels in L. whereas (OA) mass-specific rate this species. Additionally, there was no significant effect OA or OW anti-predator behavior when E. troschelii . These results highlight need for future studies integrate multidisciplinary experimental designs (i.e. physiology) span multiple biological organization make ecologically relevant predictions organisms will respond change.

CO₂-Induced Ocean Acidification Alters the Burrowing Behavior of Manila Clam Ruditapes philippinarum by Reversing GABA_A Receptor Function

Environmental Science & Technology, Год журнала: 2023, Номер 57(24), С. 8921 - 8932

Biological burrowing behavior is an important driver shaping ecosystems that being threatened by CO2-induced ocean acidification; however, the effects of acidification on and its neurological mechanism remain unclear. This study showed elevated pCO2 significantly affected behaviors Manila clam Ruditapes philippinarum, such as increased foot contraction, time, intrabottom movement decreased depth. Delving deeper into mechanism, exposure to extracellular pH [HCO3–]. Moreover, indicator GABAA receptor, a neuroinhibitor for movement, was found be closely associated with behavioral changes. In situ hybridization confirmed receptor widely distributed in ganglia muscles, mRNA level GABA concentration. However, increase ligand did not suppress but rather sent "excitatory" signals contraction. The destabilization acid–base homeostasis demonstrated induce reversal potential alteration function under pCO2. revealed affects clams altering from inhibitory excitatory.

Elevated carbon dioxide (CO2) levels can alter ecologically important behaviours in a range of marine invertebrate taxa; however, clear mechanistic understanding these behavioural changes is lacking. The majority research on the effects elevated CO2 has been done fish, focusing disrupted functioning GABAA receptor (a ligand-gated ion channel, LGIC). Yet, could induce alterations through mechanisms that disturb different components neurobiological pathway produces behaviour, including sensation, altered choices and disturbed channel-mediated neurotransmission. Here, we review potential by which may affect behaviours. Marine acid-base physiology pharmacology discussed relation to functioning. Alternative for change at are considered topics future have identified. A will be determine why there variability CO2-induced across taxa, some, but not other, affected within species identify invertebrates most vulnerable rising levels.
