Summary: This study investigated the impacts of climate change stressors on the Australasian snapper in New Zealand. The results showed that the snapper's metabolic performance remained high even in warm conditions, and they were able to adapt well to hypoxia. Therefore, despite the threat climate change poses to marine organisms, a temperature of 25°C may be metabolically optimal for the Australasian snapper in Northern New Zealand.

Summary: Understanding the mechanisms behind critical thermal maxima (CTmax) is crucial in studying ectotherm thermal tolerance. Body size plays a significant role in affecting CTmax, with larger species showing more pronounced negative relationships. Additionally, differences in brain and cloacal temperature measurements are influenced by body size, with smaller lizards exhibiting larger discrepancies.

Summary: The ecological relevance of aerobic scope in fish is closely related to habitat and lifestyle, with fast-flowing aquatic habitats favoring species with high aerobic scope and anaerobic capacity for locomotion, while slow-flowing habitats may favor hypoxia tolerance at the expense of reduced locomotor capacity.

Summary: This study analyzes the biodiversity pattern of teleost fishes and explains the rarity of sharks and rays in polar waters. It shows that the thermal sensitivity of resting metabolic rates is lower among species in teleosts but not in sharks and rays. Environmental temperature impacts physiological functions and can limit the range expansions of ectothermic species. The study explores the link between thermal physiology and biogeography and tests two hypotheses: the Universal Temperature Dependence hypothesis and the Metabolic Cold Adaptation hypothesis. The results suggest that these hypotheses hold true for teleosts but not for elasmobranchs, and that metabolic cold adaptation in teleosts may explain their higher diversity at high latitudes.

Summary: The research proposes a hypothesis about water-breathing ectothermic animals, suggesting that they regulate peak specific dynamic action response during times of warming by reducing meal sizes to protect postprandial residual aerobic scope, leading to reductions in growth.

Summary: In this experiment, the effect of temperature on the survival, growth rate, metabolism, and physiological indices of juvenile Arctic charr in Iceland was examined. The results showed that high temperatures resulted in decreased survival and growth rate, reduced feed intake, and increased stress on the cardiovascular system. However, growth rate was not limited by temperature at lower temperatures.

Summary: In this study, the metabolic rates, thermal, and oxygen-related limits of Halobatrachus didactylus were estimated for the first time. The results show that this species is remarkably resilient to acute environmental variations in temperature and oxygen content, which suggests its ability to adapt to future extreme abiotic conditions in the oceans.

Summary: The study evaluated both aerobic and anaerobic metabolic scaling in the endemic Chilean freshwater crayfish Parastacus pugnax, finding that anaerobic metabolism does not scale with crayfish size, suggesting adaptation to hypoxic environments throughout their ontogeny.

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: Anthropogenic activities and global air temperature changes have caused increased water temperatures and episodic hypoxia in estuarine and coastal systems. These alterations have had population-level effects on aquatic organisms, including changes in species-specific distributions. Individual-based models were used to investigate the effects of temperature and hypoxia on the distribution of Atlantic croaker and spot in Chesapeake Bay. The models failed to accurately reproduce the observed spatial distributions, indicating that factors other than temperature may be influencing the movement and distribution of these fish species.

Summary: The study found that rotifers exhibited clone- and condition-specific responses to hypoxia and temperature, with different response strategies equally successful in maintaining fitness levels. The important conclusion was that body size decrease at higher temperatures enabled the maintenance of aerobic scope under clone-specific, thermally optimal conditions, and there are alternative options to prevent fitness reduction under hypoxia.

Summary: This study investigates the reorganization of the metabolic transcriptional network in the brainstem of American bullfrogs during hibernation to achieve ischemia tolerance. The results suggest that improving neural performance during ischemia involves a transcriptional program for glycogen and glucose metabolism.

Summary: This study explored the use of fish community size spectrum as a complementary bioindicator in 51 natural lakes and 102 reservoirs. Results showed that the size spectrum was influenced by water quality degradation, habitat loss, and fish invasion. The size spectrum was more sensitive to habitat loss in natural lakes. Using fish community size spectrum can provide additional insights into the responses of freshwater ecosystems to global changes and improve management efficiency.

Summary: Many factors influence species' distributions, including physiological traits like aerobic scope (AS). Previous theories proposed a positive link between AS and distribution range, but a comparative study on fish species found a negative relationship between thermal peak AS and latitude range, contradicting the prevailing theory. No association was found between thermal range AS and latitudinal range in 32 species.

Summary: This article presents a systematic review of recent studies in animal behavior and physiology, revealing a lack of attention to parasite infection. Only 21.9% of the studies acknowledged the potential effects of infections on animal performance, and only 5.1% considered infection status in their analyses. The authors emphasize the importance of considering individual infection status when assessing performance of wild animals.
