Summary: Organisms have the ability to alter their physiology in response to environmental conditions, providing a short-term defense mechanism against weather extremes due to climate change. In this study, a tropical subtidal gastropod demonstrated metabolic acclimation to increased CO2 levels and heating, but acute lethal temperature limits appeared less flexible during short-term acclimation.

Summary: Long-term experimental investigations on the transgenerational plasticity (TGP) and transgenerational acclimatization to global change in marine invertebrates are sparse. The study revealed significant effects of ocean warming and acidification on sea urchins, with offspring from near-future climate conditions displaying smaller size and reduced physiological functions. The experiment also showed potential for genetic adaptation in surviving individuals after a pathogenic event, but raised concerns about negative parental effects and reduced population replenishment.

Summary: Ocean warming is predicted to challenge marine organisms, especially when combined with ocean acidification. Thermal history determines the physiological adjustments of marine organisms to climate change, with warm-acclimated individuals conserving energy to adapt to warming. However, compensatory feeding disappears when warming is combined with ocean acidification.

Summary: The study found that ocean warming has a greater impact on the growth of marine diatom Thalassiosira weissflogii over long-term selection experiments compared to ocean acidification. Many temperature response traits were influenced by ocean warming, indicating that it is the main driver for the evolution of T. weissflogii. However, adaptations resulting from warming can be constrained by ocean acidification, leading to trade-offs in photochemical performances.

Summary: This study aimed to estimate the potential risk of the combined effect of global change factors and microplastic pollution on the growth and development of the sea urchin P. lividus. The results showed that exposure to decreased pH and microplastic caused a significant decrease in larval growth, while an increase in water temperature added additional stress, resulting in lower growth and altered development of the sea urchin larvae. The combined stress of ocean warming, acidification, and microplastic pollution may threaten sea urchin populations and have a potential impact on coastal ecosystems.

Summary: Understanding how ocean acidification and warming affect consumption rates of predators and herbivores in marine ecosystems is crucial for predicting responses to global change. Studies show that both OA and warming can directly impact consumers, but there is high variability in consumption rates, likely due to species adaptation and methodological differences. Exposure to OA may reduce consumption rates on average, but rates can increase when both consumers and their resources are exposed to the same conditions concurrently.

Summary: The Southern Ocean is responding rapidly to human-induced global change, and serves as a valuable indicator for the impact of ocean warming and acidification on marine species and ecosystems. The authors provide the largest carbonate mineralogical dataset for Southern Ocean bryozoans, highlighting their potential as effective monitors for studying the effects of ocean warming and acidification. They find that bryozoan mineralogy changes significantly with decreasing latitudes and increasing seawater temperature, suggesting that seawater temperature may be a significant driver of global variations in bryozoan mineralogy.

Summary: Ocean warming significantly reduces successful symbiont infection and geometric diameter of Platygyra daedalea recruits, while high pCO(2) has little impact. There is an inverse relationship between symbiont infection rates and survivorship, particularly at high temperatures. The study also reveals a high degree of plasticity in early symbiosis with implications for coral-algal partnerships under future climatic conditions.

Summary: Research shows that crustose coralline algae (CCA) respond negatively to low and medium emissions scenarios of warming and acidification, and may be adversely affected by 2030 if current emissions persist. Significant declines in growth rates and increases in bleaching were observed in the high emission scenario. These findings underscore the urgent need to take action to protect CCA and the valuable ecosystem services they provide.

Summary: This study investigates the frequency distribution of behavioral and physiological phenotypic traits in fish under natural and controlled laboratory conditions. The results show that ocean acidification leads to a decrease in shy phenotypes, while ocean warming results in both a decrease and increase of bold phenotypes. The variance within populations is reduced in natural conditions compared to control conditions, suggesting potential reshaping of species interactions. However, these phenotypic alterations do not affect fish body condition.

Summary: Ocean warming and acidification pose a severe threat to pteropods in the Arctic by reducing their survival and causing the dissolution of their shells. Lipids, especially phospholipids, play a crucial role in the early-stage pteropods. Our experimental study shows that elevated temperatures and high CO2 concentrations lead to a significant decrease in total lipids, mainly due to the reduction of phospholipids. This reduction may compromise cell differentiation and energy balance in the early-stage larvae. The negative effects of warming on lipid metabolism may be a more immediate threat to pteropods than shell dissolution effects caused by acidification.

Summary: Alternative splicing is a molecular mechanism that allows a gene to encode multiple transcripts and proteins. This study explored the patterns of alternative splicing in the liver of a coral reef fish in response to a marine heatwave. The results showed that acute warming during the onset of the heatwave had a greater impact on alternative splicing than continued exposure to elevated temperatures, and after the heatwave, the fish showed differential splicing of genes related to cyto-protection and post-damage recovery. These findings reveal the role of alternative splicing in the response of coral reef fish to thermal stress.

Summary: This study examines the combined effects of climate change on the yellowfin tuna population and finds that acidification will have smaller impacts compared to ocean warming, but will still affect the dynamics of the population. The distribution of yellowfin tuna is projected to shift eastward, and acidification is expected to weaken the increase in abundance in the eastern Pacific.

Summary: The parental environment can influence offspring phenotypes, but the specific factors are not well understood. This study explores the effects of parental exposure to elevated temperature on a coral reef fish. The results show that within a generation, coral reef fish can maintain performance through phenotypic plasticity, but between generations, warming may have negative impacts. This research provides important insights for accurately predicting how organisms will respond to climate change.

Summary: Body condition is an important indicator of the overall health and energetic status of fishes. The commonly used Fulton's condition factor requires length and mass measurements, but mass can be difficult to obtain in large species. Girth measurements can replace mass for wild pelagic sharks, but the validity of this method has not been fully confirmed.

Summary: This study examined the differences in skeletal muscle morphological and metabolic properties in neonate epaulette sharks exposed to their current-day ambient or projected end-of-century habitat temperatures. The results showed that sharks hatched earlier but were similar in body size at the end of the study. Muscle fiber size, nuclear density, and capillary density were similar between temperature regimes. However, fiber density was lower, satellite cell density was higher, and fibers associated with satellite cells were smaller in sharks reared at the projected end-of-century temperature.

Summary: Reef shark species have experienced significant declines due to human activities, and their conservation requires policies at local, federal, and global levels. This study monitored the blacktip reef shark population around Moorea and within the world's largest shark sanctuary for nine years. The results indicate that local and likely federal policies have been effective in maintaining stable juvenile shark density. However, some nursery areas showed increasing shark densities, potentially due to changes in reproductive behavior or habitat type and resources. Water temperature did not have a significant impact on juvenile shark density over time.

Summary: This study monitored and sampled blacktip reef sharks in nursery habitats to improve understanding of shark reproductive behavior and biology. The research revealed evidence of plastic philopatric behavior, with some female sharks changing parturition areas between seasons while others consistently returning to the same site. Additionally, resource allocation within some shark litters appeared to be unbalanced. These findings contribute to our knowledge of shark populations and can inform future conservation strategies.

Summary: Puffer and porcupine fishes have the ability to inflate themselves by swallowing seawater to defend against predation, but this mechanism leads to the loss of stomach function. Through studying the stomach phenotype and genotype of four different fish species, it was found that this inflation mechanism is only present in Tetraodontiformes and is not a selective pressure for stomach loss in other gastric inflating fishes.
