Summary: The kelp forests of the California Current System have experienced prolonged marine heatwave (MHW) events that coincide with the life history events of many marine invertebrates. This study focused on the purple sea urchin and examined the effects of MHWs on gametogenesis and whether it induces transgenerational plasticity in thermal tolerance. The results showed that embryos from MHW-acclimated females had higher thermal tolerance and increased protein concentration in their eggs.

Summary: Climate change poses constant and more severe environmental challenges to coastal and marine species. Marine heatwave events have serious impacts on the fitness and survival of species, especially during the sensitive early-life stages. A study on planktonic larvae of the fiddler crab Leptuca thayeri using historical data and climate change predictions found that higher temperatures and changing pH conditions affect larval survival and physiology, leading to potential reductions in larval recruitment and stocks with negative ecological effects on estuarine habitats.

Summary: Due to the unusual warm ocean condition fueled by a marine heatwave, Typhoon Bavi became the strongest typhoon in the East China Sea in the past decade. The shallow water depth and strong salinity stratification in the ECS prevented typhoon-induced cooling, resulting in high sea surface temperatures that enhanced the typhoon's heat flux. Interestingly, the typhoon itself likely contributed to the rapid development of the marine heatwave. This study provides important insights into the interaction between typhoons and marine heatwaves, which are becoming increasingly significant under climate change.

Summary: The study in French Polynesia found that a marine heatwave in 2019 caused widespread coral bleaching and mortality, disproportionately affecting the largest individuals of key coral genera. Heat stress from the event significantly reduced overall fecundity of corals and led to a decline in survivorship of newly-settled coral recruits. The findings highlight the potential long-term impacts of marine heatwaves on coral reef ecosystems.

Summary: Significant questions remain about the effects of climate change on ecosystems structured by abiotic stress. This study found that a multiyear marine heatwave led to major shifts in intertidal community dynamics and zonation, impacting both seaweed and invertebrate populations. The results suggest that intense and lasting warming events may restructure ecological dominance patterns and reduce the habitability of ecosystems along abiotic stress gradients.

Summary: Developing new tools to assess the health of cultivated shellfish larvae is crucial for the aquaculture industry. In a large-scale trial, mussel embryos were exposed to copper in the presence of EDTA, and metabolomics analysis was used to identify potential biomarkers for monitoring and characterize the mechanisms of metal toxicity. The results showed that low levels of bioavailable copper caused coordinated fluctuations in metabolite profiles, while lethal levels of copper induced severe metabolic dysregulation and cell/organism death.

Summary: Animal behavior is driven by the fundamental need to feed and reproduce, which can be inferred from the spatiotemporal variations in biological signals. This study investigated the environmental correlates of vocalizations in blue whales and found that D calls were associated with foraging effort, while song intensity showed a seasonal pattern aligned with the timing of conception. Furthermore, a marine heatwave resulted in reduced foraging and lower reproductive effort in blue whales.

Summary: Marine heatwaves (MHWs) in the South China Sea during summer, especially near the Nansha Islands and Beibu Gulf, have shown a significant increasing trend in the MHW days, duration, and frequency during 1982-2020. This is likely due to the anomalous intensification of the western North Pacific high pressure system causing disruptions in the summer southwest monsoon, leading to severe basin-wide MHWs in the South China Sea.

Summary: Marine heatwaves, prolonged periods of warm seawater, can reshape marine communities and ecosystems. Researchers propose a functional trait approach to understand which species and communities are most vulnerable to these events and predict how species distribution and community composition may shift over time. This approach aims to unify extreme events and long-term environmental trends as drivers of ecological change, enhancing the ability to make informed management decisions.

Summary: This study surveyed the seasonal biomass and cover of subtidal macroalgal and sessile invertebrate communities in Hong Kong. The results showed that shallow assemblages were more influenced by environmental factors and exhibited seasonal patterns, while deeper communities had less biomass but were more stable across seasons. Oysters, barnacles, and live corals dominated the sessile invertebrate communities at both depths. This study establishes a baseline for assessing future changes in algal productivity and community composition.

Summary: Distributional shifts in species ranges provide critical evidence of ecological responses to climate change. Assessments of climate-driven changes typically focus on broad-scale range shifts, but overlook ecological consequences at regional and local scales. This study uses an ecosystem engineer species, Sabellaria alveolata, to assess climate-driven changes within its fragmented distribution using landscape ecology metrics and species distribution modeling.

Summary: Macroalgal forests play a vital role in coastal ecosystems globally, but the unique environmental conditions in climatic transition zones can limit their productivity and persistence. A study on a seaweed in Hong Kong showed that it had the highest growth in cooler conditions but surprisingly had the highest photosynthetic rates in summer, after a period of senescence and dormancy. This discrepancy may enable the seaweed to withstand higher temperatures, resisting predicted range shifts due to ocean warming. However, other seaweeds in climatic transition zones may face shorter growth seasons, longer dormancy, and reduced biomass production, potentially reducing the overall productivity of these algal forests.

Summary: Human activities have caused degradation of ecosystems globally, resulting in a recovery debt. Restoration efforts have shown initial success in increasing biodiversity and abundance of species, but the rate of recovery decreases over time, leaving a 35% shortfall in global recovery compared to the predisturbed state. Future coastal development should consider not only immediate damage but also potential generational loss.

Summary: Reef building oysters provide ecological benefits and ecosystem services, but the impact of changing environmental conditions on their microbial communities and ecological role is unclear. In this study, oysters were exposed to acidification and hypoxia, resulting in physiological stress, changes in microbial community structure, and potential nutrient cycling loss. These findings suggest that the oyster holobiont may experience negative effects under hypoxia and multi-stressor conditions.

Summary: The Barents Sea, as the largest Arctic shelf region, plays a vital role in supporting commercial fisheries. The ecosystem of this region is significantly influenced by both warm Atlantic Water (AW) and cold Arctic Water (ARW), resulting in distinct frontal zones. This study found that copepod populations, particularly herbivorous copepods, were most abundant and productive in the Polar Front, as well as in the eastern frontal zones. The geographic positions of sampling stations, depth, and chlorophyll a concentration were identified as the main factors influencing copepod biomass and production.
