Summary: The response to hypoxia of Mesonauta festivus and Aequidens pallidus varies, with A. pallidus showing lower tolerance to hypoxia due to its natural normoxic environment, while M. festivus exhibits a higher decrease in metabolic rate and activation of anaerobic metabolism. The ability to tolerate hypoxia is closely related to the species' metabolic depression, indicating the importance of preserving natural dissolved oxygen levels in maintaining fish biodiversity.

Summary: The study revealed that during flight in oxygen levels near the Pcrit, mass-specific metabolic rates declined precipitously with mass both across and within castes, suggesting strong size limitations on oxygen delivery, but only during extreme conditions when demand is high and supply is low.

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: Extended exposure to low pO(2) leads to diverse effects on signaling cascades, with redox homeostasis achieved by day 3 but energy metabolism perturbed, leading to increased immune/inflammatory signaling. Protein interactions play a crucial role in achieving redox balance and survival during extended low pO(2) exposures.

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: Climate change and increasing sea surface temperature have worsened ocean deoxygenation, affecting the metabolic response and tolerance range of Caribbean coral species and their algal symbionts. This study found that they exhibited varying degrees of tolerance to hypoxia, providing insights into the community composition of reefs under changing climate and guiding restoration efforts.

Summary: The recent proliferation of invasive blue crab in the Mediterranean Sea is a consequence of climate change and globalization. This study investigates the thermal tolerance of the blue crab and predicts its potential distribution in the Mediterranean Sea under current and future temperature conditions. The findings provide valuable information for the management and risk assessment of this impactful crustacean.

Summary: The study revealed that changes in photosynthetic and respiration rates in coastal marine habitats can lead to considerable variability in ecosystem metabolism on different time scales, from diurnal to seasonal. Different habitats showed diverse responses to changes in pH and DO, emphasizing the importance of enhancing seagrass and macroalgae cultivation to maintain estuarine ecological balance in the face of predicted declines in pH and oxygen levels.

Summary: The research found that fipronil has severe toxic effects on stingless bees, compromising their physiological functions. The exposure to this insecticide leads to decreased respiration rate and disrupted structure and function of the Malpighian tubules in the bees. In addition, ingestion of fipronil increases oxidative stress, autophagy, and apoptosis, further impairing the bees' cell recovery ability.

Summary: This study simulated hypoxic stress to distinguish hypoxia-tolerant and hypoxia-sensitive individuals in golden pompano. Analysis of mRNA expression profiles in the brains and livers under hypoxia revealed differences in metabolism pathways and functions related to signal transduction between the two groups.

Summary: Obstructive sleep apnea (OSA) is a common disease associated with dyslipidemia, insulin resistance, and metabolic syndrome. Brown adipose tissue (BAT) is believed to affect systemic glucose tolerance through adaptive thermogenesis, while chronic hypoxia affects the function and metabolism of BAT. This study shows that chronic hypoxia leads to browning of BAT, but also tissue-specific and systemic insulin resistance.

Summary: In vascular smooth muscle cells, Cyglobin (Cygb) mediated NO metabolism is primarily dependent on the reducing systems cytochrome b5 (B5) and cytochrome b5 reductase (B5R), with cytochrome P450 reductase (CPR) playing a minor role.
