Summary: The authors utilize machine learning models to identify multifactor tipping points of global marine phytoplankton. The study reveals that temperature and carbon dioxide are the key risks, and predicts that the tipping points of production and resistance in tropical areas will be crossed by 2100.

Summary: Through studying coral-associated barnacles, we found that the morphology of their attachment organs is similar regardless of host species, and the settlement and metamorphosis processes are influenced by chemical cues. Larvae of barnacles with different host specificities only settle on their specific hosts, with one species displaying exploratory behavior before settlement while the other species settles directly. These findings suggest that host specificity and exploratory behavior in barnacle larvae are results of adaptive evolution.

Summary: Understanding the effects of OA and warming trend on marine organisms, particularly on early reproductive traits, is vital for predicting their response to climate change. In this study, exposure to elevated pCO(2) and higher temperatures had significant impacts on the sorus photosynthetic performance and germination rate of meiospores in Lessonia trabeculata, indicating potential threats to the species' establishment and ecosystem functioning.

Summary: The study revealed that the eastern oyster demonstrates significant recovery and acclimation when adapting to ocean acidification, supported by transcriptomic analysis. The functions of differentially expressed genes include cell differentiation, development, biomineralization, ion exchange, and immunity. The findings suggest acclimation as a mode of resilience to ocean acidification.

Summary: Ocean acidification can affect marine molluscs, but transgenerational plasticity may mitigate some effects. This study investigated how the microbiome can be influenced by transgenerational exposure to ocean acidification in Sydney Rock oysters. The results showed that parental exposure to elevated PCO2 altered the bacterial community composition in both eggs and larvae, with certain Rhodobacteraceae ASVs increasing or decreasing in abundance. These findings suggest that the transfer of maternal microbiomes to larvae is affected by exposure to ocean acidification and may contribute to transgenerational plasticity.

Summary: Anthropogenic carbon emissions and climate change have led to rapid warming, acidification, and deoxygenation in the ocean, causing increasing stress on marine ecosystems. This study demonstrates the ability to predict dissolved inorganic carbon, dissolved oxygen, and temperature in the surface and subsurface ocean multiple months in advance, with particularly high predictive skill observed in key regions such as the Northeast Pacific.

Summary: Aquatic ecosystems contribute 50% of global productivity and play a crucial role in mitigating climate change. Factors such as water temperature, ocean acidification, nutrient availability, deoxygenation, and exposure to UV radiation interact to either enhance or decrease productivity. While ocean warming and deoxygenation may have opposite effects on mitochondrial respiration, they synergistically affect plankton migration and N-2-fixation of diazotrophs. Ocean acidification and elevated pCO(2) have controversial effects on marine primary producers, but they can worsen viral attacks on microalgae and reduce calcification of algal calcifiers when combined with UV radiation. Field observations over a long period of time are limited, but future studies are expected to explore the responses and mechanisms to multiple drivers in different regions.

Summary: This study examines the impacts of ocean warming and acidification on larval Atlantic surfclams. Results show that ocean warming increases feeding, growth and biomineralization, but decreases swimming speed and pelagic larval duration. Ocean acidification increases respiration but reduces immune performance and biomineralization. Additionally, changes in energy allocation and profiles of responses are observed under climate change.

Summary: Global projections for ocean conditions in 2100 predict significant changes in the North Pacific. Local processes in the California Current System can modify these changes. However, downscaled multi-model climate projections demonstrate that future changes in biogeochemical variables in the CCS are amplified, dampened, and spatially variable compared to global models.

Summary: This study investigates the mechanisms of histamine-induced larval settlement in barnacles. Transcriptomic analyses reveal differentially expressed genes involved in the mitogen-activated protein kinase signaling pathway. Functional genes related to cyprid settlement are identified, including those involved in energy metabolism. AdipoR is identified as an important gene that affects cyprid settlement through regulation of energy metabolism.

Summary: Coastal macroalgae, such as Saccharina japonica, can be affected by global and local stressors like ocean acidification and heavy-metal pollution. This study examined how juvenile S. japonica responded to different levels of pCO(2) and copper concentrations. The results showed that the growth and biochemical compositions of the macroalgae were influenced by the interaction between copper concentration and pCO(2) level. Excess copper inhibited growth, but this effect was mitigated under high pCO(2) conditions.

Summary: This study investigated the impact of seagrass on the larval development of calcifying sea urchins under ocean acidification conditions. The results showed that seagrass can mitigate the negative effects of ocean acidification, reducing larval abnormalities and increasing total body length.

Summary: The unprecedented rate of increased CO2 levels in the ocean has led to ocean acidification, which can disrupt physiological and developmental processes in marine organisms like oysters. Despite this, some species may cope with OA stress through modifications in gene and protein expressions. The study found that lower pH levels (7.4) influenced DNA methylation patterns in larval genes of Crassotrea hongkongensis, affecting both metamorphosis success and substrate selection.

Summary: The rapid global spread of COVID-19 and other anthropogenic threats such as global climate change are posing significant economic challenges to the aquaculture sector. A positive correlation between the impacts of the pandemic and anthropogenic stressors was detected, with different effects on various parts of the supply chain. The use of integrated multitrophic aquaculture (IMTA) methods may enhance resilience to multiple stressors, providing different market options during the COVID-19 pandemic.
