“…However, the effects of OA on marine ecosystems will depend on the relative sensitivity and tolerance of different species, and their ability to acclimatize and adapt to the environmental changes brought about by rising CO 2 levels [2]. Recent studies show that increased pCO 2 levels can affect the growth, survivorship and physiology of some marine fishes [3][4][5][6][7]. Elevated CO 2 has also been shown to alter behaviours in a wide variety of fish [8][9][10] and invertebrates [11][12][13].…”

Knowledge of adaptive potential is crucial to predicting the impacts of ocean acidification (OA) on marine organisms. In the spiny damselfish, Acanthochromis polyacanthus , individual variation in behavioural tolerance to elevated pCO 2 has been observed and is associated with offspring gene expression patterns in the brain. However, the maternal and paternal contributions of this variation are unknown. To investigate parental influence of behavioural pCO 2 tolerance, we crossed pCO 2 -tolerant fathers with pCO 2 -sensitive mothers and vice versa, reared their offspring at control and elevated pCO 2 levels, and compared the juveniles' brain transcriptional programme. We identified a large influence of parental phenotype on expression patterns of offspring, irrespective of environmental conditions. Circadian rhythm genes, associated with a tolerant parental phenotype, were uniquely expressed in tolerant mother offspring, while tolerant fathers had a greater role in expression of genes associated with histone binding. Expression changes in genes associated with neural plasticity were identified in both offspring types: the maternal line had a greater effect on genes related to neuron growth while paternal influence impacted the expression of synaptic development genes. Our results confirm cellular mechanisms involved in responses to varying lengths of OA exposure, while highlighting the parental phenotype's influence on offspring molecular phenotype.

“…For example, some evidence suggests that organisms experience increased sensitivity to ocean acidification when concurrently exposed to elevated temperatures (Kroeker et al, 2013). From our literature review, it is clear that research effort over the last decade has focused more on experiments that assessed the combined effects of multiple stressors, including both climate and non-climate related factors (e.g., Burnell et al, 2013;Al-Janabi et al, 2019;McMahon et al, 2020). Despite this, single factor ocean acidification experiments, the "novel stressor" from the 2000s (Wernberg et al, 2012) continued to be prevalent in the 2010s.…”

“…Second, the number of transgenerational experiments, which primarily tested if offspring can adapt and acclimate to climate changes if their parents are exposed to stress, increased more than 11-fold between the two decades. Transgenerational experiments from the most recent decade have demonstrated that exposure over generations can reduce the negative effects to ocean warming and acidification on offspring, for example by restoring aerobic scope (Donelson et al, 2016), body size (McMahon et al, 2020) and alter sex ratios (Donelson and Munday, 2015). However, transgenerational responses to climate change have also shown to be negligible (Uthicke et al, 2013) or negative (Welch et al, 2014;Griffith and Gobler, 2017;de Bettignies et al, 2018), demonstrating that these effects can be very complex and difficult to predict.…”

Another Decade of Marine Climate Change Experiments: Trends, Progress and Knowledge Gaps

Anthropogenic climate change is a significant driver of change in marine ecosystems globally. To improve mechanistic understanding of the impact of climate-related stressors, experimental work on marine organisms has intensified in recent decades. A previous synthesis paper published nearly a decade ago established that Marine Climate Change Experiments (MCCEs) published from 2000–2009 were primarily laboratory-based and focused on single stressors and individual focal temperate species. Using consistent methodology, we compared the 2000–2009 analysis to experiments published in the following decade (i.e. 2010–2019) to assess recent trends in MCCEs and to determine to what extent knowledge gaps and research priorities have been addressed. The search returned 854 papers, vs. 110 from the 2000s, indicating considerable intensification of research effort and output. We found again that single species studies were most common, particularly with benthic invertebrates as model organisms, and that laboratory-based research comprised over 90% of all studies. However, multiple stressor experiments increased substantially, where tests for interaction effects between ocean acidification (i.e., increased pCO2) and warming were particularly common. Furthermore, a wider range of model species were studied and more community-level experiments were conducted in the 2010s compared with the 2000s. In addition, studies on behavioral responses, transgenerational effects, genetic adaptation and extreme climatic events increased markedly. These recent advances in MCCEs have undoubtedly improved understanding of how climate change will affect marine organisms and the communities and ecosystems they underpin. Going forward, biases in the type and distribution of model organisms should be addressed to enhance general understanding of responses to environmental change. Similarly, experiments should manipulate a greater number and range of climate and non-climate factors and increase the number of target organisms to increase realism. Finally, where possible, further research should be combined and contextualized with field-based experiments and observations to better reflect the complexity of marine ecosystems and yield more representative responses to ocean climate change.

“…High CO 2 has also been documented to impact the reef fish physiological traits such as escape performance ( Allan et al, 2013 ; Allan et al, 2014 ), metabolism ( Wisenden, 2012 ; Couturier et al, 2013 ; Rummer et al, 2013 ; McMahon et al, 2020 ), and reproduction ( Miller et al, 2013 ; Welch and Munday, 2016 ). A meta-analysis of fish metabolic responses to OA revealed that there is an increase on resting metabolic rate ( Ṁ O 2Rest ), but there seems to be no overall effect of OA on fish absolute aerobic scope ( Ṁ O 2Max - Ṁ O 2Rest ) ( Hannan and Rummer, 2018 ).…”

Access to Cleaning Services Alters Fish Physiology Under Parasite Infection and Ocean Acidification

et al. 2022

Cleaning symbioses are key mutualistic interactions where cleaners remove ectoparasites and tissues from client fishes. Such interactions elicit beneficial effects on clients’ ecophysiology, with cascading effects on fish diversity and abundance. Ocean acidification (OA), resulting from increasing CO2 concentrations, can affect the behavior of cleaner fishes making them less motivated to inspect their clients. This is especially important as gnathiid fish ectoparasites are tolerant to ocean acidification. Here, we investigated how access to cleaning services, performed by the cleaner wrasse Labroides dimidiatus, affect individual client’s (damselfish, Pomacentrus amboinensis) aerobic metabolism in response to both experimental parasite infection and OA. Access to cleaning services was modulated using a long-term removal experiment where cleaner wrasses were consistently removed from patch reefs around Lizard Island (Australia) for 17 years or left undisturbed. Only damselfish with access to cleaning stations had a negative metabolic response to parasite infection (maximum metabolic rate—ṀO2Max; and both factorial and absolute aerobic scope). Moreover, after an acclimation period of 10 days to high CO2 (∼1,000 µatm CO2), the fish showed a decrease in factorial aerobic scope, being the lowest in fish without the access to cleaners. We propose that stronger positive selection for parasite tolerance might be present in reef fishes without the access to cleaners, but this might come at a cost, as readiness to deal with parasites can impact their response to other stressors, such as OA.
