Summary: The study found that heat tolerance differences in Daphnia magna may be related to metabolic compensation rather than genetics. Additionally, D. magna acclimated at 25 degrees Celsius showed a greater ability to slow down respiration at high temperatures compared to those acclimated at 10 degrees Celsius.

Summary: Research suggests that in future extremely warm summer conditions, blue mussels can enhance heat tolerance by regulating metabolic demand, reducing the risk of heat-induced supply and demand mismatch, but the capacity to acquire such heat tolerance through acclimation is relatively minor.

Summary: This study demonstrates that components of the molecular oxygen-sensing machinery are robustly activated across tissues under chronic hypoxia, inducing repressive transcriptional and post-transcriptional epigenetic marks in the hypoxia-acclimated brain. Additionally, evidence supports the role of membrane remodeling and mitochondrial function in promoting metabolic suppression in goldfish.

Summary: The study investigated the effects of daily temperature fluctuation on development characteristics in five species of fruit flies with different thermal resistance. Results showed significant differences in responses to fluctuating developmental temperatures among species of the same genus with different thermal resistance levels, indicating the importance of considering multiple traits in interpreting responses to fluctuating temperatures.

Summary: For marine animals with biphasic life stages, physiological constraints on early stages could explain adult distributions and life history traits. In the case of the Mytilus galloprovincialis and Perna perna mussels, their metabolic regulation capacities in response to temperature differ as adults but are similar during the post-settlement recruit stage. Monthly variations in metabolic patterns indicate unexpected high plasticity in response to recent seasonal thermal history for both species.

Summary: Uncertainty in parameters in ecological models can be incorporated by treating parameters as random variables with distributions. Recent advances in uncertainty quantification methods provide new approaches for analyzing models with random parameters. Modelling key parameters as random variables changes the characteristics of the model. The computational efficiency of polynomial chaos methods helps in better predicting and synthesizing models with data.

Summary: Reversible phenotypic flexibility allows organisms to adjust to environmental conditions, and the costs and constraints of this flexibility are not well understood. This study found that high basal metabolic rate (BMR) is positively correlated with flexibility in BMR, but flexibility in maximum cold-induced metabolic rate (M-sum) or metabolic scope does not generally incur elevated costs.

Summary: The cytoplasmic inheritance of human chloramphenicol resistance, which is mediated by mitochondrial DNA (mtDNA), has been discovered for almost half a century. Mutations in mtDNA have been found to cause severe inheritable metabolic diseases and neurodegenerative diseases. Recent studies have shown that impaired mitochondrial functions and loss of mitochondrial stress resilience can influence animal behaviors. In addition, the activation of the tryptophan-kynurenine metabolic system, which is related to stress and inflammation, has been linked to the development of neurological and psychiatric disorders.

Summary: This article investigates the metabolic scope, performance, and tolerance of juvenile European sea bass reared under high water temperatures. It finds that European sea bass can maintain high performance at 28 degrees Celsius, but critical survivability thresholds appear sharply close to 33 degrees Celsius.

Summary: GIRK1-dependent signaling is critical for maintaining optimal PrL function and behavioral control in male mice, but not in females. Stress-induced deficits in affect regulation and cognition are associated with disruption of this signaling pathway, providing a potential therapeutic target for improving quality of life.

Summary: An L-p-version of the generalized trace-free Korn inequality is proven for incompatible tensor fields P in the domain Ω, with specific conditions on the boundary. The estimates also hold true for tensor fields with vanishing tangential trace, indicating a strong relationship between the norms of the tensor fields in different spaces.

Summary: The experimental study demonstrated that the decline in total phytoplankton abundance under high CO2 conditions was primarily driven by ecological shifts and to a lesser extent by evolutionary changes. This suggests that intraspecific diversity changes may occur regardless of CO2 levels, contributing to the low evolutionary contribution observed.

Summary: The study found that the richness, prevalence, and abundance of parasites in Mytilus galloprovincialis are influenced by both biotic (host size, density, and local parasite richness) and abiotic (eutrophication and salinity) factors. Local parasite richness was the most relevant factor driving parasite species richness, and prevalence was mainly driven by eutrophication levels.

Summary: This study evaluates the thermal response of the infective larval stage of the parasite Himasthla elongata, finding that infection renders the host more susceptible to elevated temperatures and warming has adverse effects on the parasite's transmission to the bivalve host.

Summary: Experimental ecology has recently focused on regional to local environmental fluctuations in the context of global climate change. Marine heatwaves pose significant threats to marine organisms, but studies including fluctuating thermal stress are rare and often lack long-term environmental data. This study evaluated 22-year high-resolution sea surface temperature data to assess the occurrence of heatwaves and cold-spells in a temperate coastal marine environment. The results demonstrate that heatwaves decrease feeding and activity of the common sea star Asterias rubens, with longer heatwaves having a more severe and lasting impact on feeding pressure and growth. Heatwaves with interruptions have a minor impact compared to continuous heatwaves, and the impact diminishes with repeated heatwave events.

Summary: Low-salinity stress can severely affect the fitness of marine organisms. The organic osmolyte pool plays an important role in low-salinity acclimation, while inorganic osmolytes are involved in long-term cellular osmoregulation in most species.

Summary: Salinity is a common stressor for decapod crustaceans, and larval stages determine their tolerance and potential for dispersal. This study examined the combined effect of salinity and temperature on the larval development of the decapod Hemigrapsus takanoi. Results showed that increasing salinity favored larval development and survival, but the population may be restricted from spreading to lower salinity areas. Additionally, desalination and rising temperatures in the Baltic Sea may pose additional stress to the existing population.

Summary: Salinity is a major factor affecting marine organisms. This study conducted a systematic review and meta-analysis on osmolytes in marine invertebrates acclimated to reduced salinity. The findings suggest that tissue concentrations of certain organic compounds and sodium are consistently reduced across different phyla, indicating the utilization of intracellular inorganic ions as a response system during acute exposure to low salinity stress. However, there are still research gaps in quantifying salinity-induced long-term changes in intracellular ion concentrations and compiling a complete intracellular osmolyte budget. Best-practice guidelines are suggested to better understand the mechanisms of salinity acclimation in marine invertebrates.

Summary: Climate change increases extreme events in the sea, especially in coastal habitats. The impacts of heatwaves and upwelling events on a temperate keystone predator, the starfish Asterias rubens, were experimentally tested. It was found that prior exposure to present-day heatwaves alleviated upwelling-induced stress, indicating cross-stress tolerance. However, future projected heatwaves caused 100% mortality of starfish, indicating extensive mortality under intensified conditions.

Summary: Global warming can impact the transmission of infectious diseases by affecting the release of cercarial stages from their hosts in trematode parasites. However, we have limited knowledge about the emergence patterns of cercariae from high temperature environments. This study investigated the effect of temperature on cercarial emergence of two trematode species from mud snails in the Persian Gulf, finding that they have the warmest recorded thermal optima among aquatic trematodes.
