Summary: Animal flight consumes metabolic energy at a higher rate and dissipates most of it as heat. During flight, heat is dissipated through forced convection, while during rest, the head and trunk are the main areas involved in heat dissipation. The surface temperature of the legs increases with flight duration. The methodology developed in this study can be used to assess the impact of climate change on bird behavior.

Summary: Windcatchers provide effective low-energy ventilation and summer passive cooling in temperate climates. However, their use in winter is limited due to significant ventilation heat loss and potential discomfort. This study evaluates the applicability of windcatchers in low-temperature conditions, highlighting the need for control strategies to reduce over-ventilation and the integration of heat recovery or thermal storage to enhance winter thermal conditions.

Summary: This study investigates the propagation of a premixed flame in micro-channels with smooth non-slip isothermal walls, focusing on the dynamics of flame extinction. Numerical simulations show that initial flame acceleration occurs after ignition at the closed end, but at a slower rate and for a shorter duration compared to the adiabatic case. Heat loss to the walls leads to changes in the flame front shape and eventual flame extinction.

Summary: The study found that snow buntings have a limited heat tolerance, experiencing heat stress when air temperatures are below their body temperature. This suggests that their well-developed cold tolerance may come at the cost of reduced heat tolerance, potentially impacting their ability to cope with warming Arctic temperatures.

Summary: To meet the increasing demands for bandwidth in 5G and 6G communication technology, the development of new dielectric substrates with low dielectric loss and improved thermal conductivity is essential. This study focuses on designing composites with low dielectric loss and high thermal conductivity for microwave applications involving high power and high frequency. The fabrication process of high-density electroceramic composites using sodium molybdate as the dielectric material and hexagonal boron nitride as the filler with higher thermal conductivity is described. The physical properties of the composites were characterized and analyzed based on filler volume, temperature, and frequency.

Summary: The study introduces the use of wrist-mounted wearable devices to monitor environmental and physiological responses for thermal comfort assessments, and evaluates their feasibility through two sets of experiments. Findings show that data obtained through the wearables can predict core temperature non-invasively and demonstrate a direct connection between air temperature at the wrist and individuals' perceived activity levels.

Summary: The aquifer thermal energy storage (ATES) system is an efficient method to address the energy supply-demand gap. Heat storage and preservation abilities play a crucial role in the success of ATES projects. However, previous studies have mainly focused on heat storage and recovery, neglecting the heat preservation ability of aquitards. Additionally, the effects of key factors on heat losses into aquitards and the appropriate selection of reservoirs for heat storage remain unclear. This study comprehensively evaluates ATES thermal performance by defining heat loss efficiency, analyzing the effects of key factors, and recommending optimal reservoirs for heat storage.

Summary: This study investigated the mechanisms of heat transfer and thermal regulation in electrically heated footwear using numerical simulation and experiments. Comparing two temperature control modes, it was found that the mode regulating temperature based on human skin had better performance and lower energy consumption. The properties of the heating pad and inner fabric layer were key factors affecting thermal regulation, while environmental temperature and heating power also played important roles in energy efficiency.

Summary: The study evaluated the intrinsic and extrinsic drivers of sex-specific sensitivity in the postnatal growth of Imperial Shag chicks, finding that singletons experienced suboptimal growth in poor years, with males being more sensitive than females. In two-chick broods, males required the most favorable environment to achieve the highest growth, while females maintained maximum growth rates regardless of the social environment.

Summary: The study focused on using animal-borne video cameras and accelerometers to analyze the prey capture behaviors of Magellanic Penguins, with the K-Nearest Neighbor algorithm proving effective in identifying these behaviors. The research found that energy expenditure during captures was significantly higher than during control diving periods and that the K-NN method provided accurate estimates of prey consumption.

Summary: The study indicates that Magellanic penguins show significant isotopic niche fluctuations between breeding seasons, primarily influenced by prey fish. The size of the isotopic niche is negatively correlated with prey fish biomass and their contribution in penguin diet. Additionally, the trophic level of Magellanic penguins increases with latitude, corresponding to the size distribution of their main prey and indicating that penguins from different colonies target different size classes of prey.

Summary: Leg rings have been found to affect the diving performance of Imperial Shags, especially in terms of foot-stroke amplitude and overall efficiency. While the impact is small and may not affect reproductive success, researchers should be cautious about the potential cumulative effect of attaching leg rings to foot-propelled diving species.

Summary: Researchers have found that penguins adopt a movement strategy that saves time, distance, and energy by selecting the shortest route to their destination and quickly returning to their nest. This strategy allows them to enhance their navigational capacities in challenging environments where vision is compromised.

Summary: This study reveals unusually high mercury concentrations in southern rockhopper penguins in the Southwest Atlantic Ocean. The variation in mercury concentrations among colonies is primarily determined by location rather than trophic position. The findings highlight the presence of a mercury hotspot in the Patagonian Shelf, located at the southern tip of South America. Regional and colony-based seabird conservation management is necessary in the presence of high local variability and plasticity in foraging habits.

Summary: The lower abundance, biomass, and homogenization of sizes of herbivorous fish caused by overfishing may lead to a disproportionate loss of functions. This study compares isotopic niche breadth, redundancy, and resource use in a herbivorous fish community to investigate the extent to which fishing affects species niche and functions. The results suggest that within the marine protected area, fish may have a greater amplitude of isotopic niche and greater niche overlap. This finding is consistent with previous studies that suggest the delimitation of marine protected areas can contribute to the redundancy of functions and resilience of coral reefs. More isotopic characterization of resources within the MPA is needed to determine if fish are using different resource species or the same ones.

Summary: The research in central-southern Chile found that crustaceans and demersal fish caught with bottom trawling clustered into three groups based on stable isotope values. Different species showed varying degrees of specialization within their own groups, with overlap in isotopic niches between populations. This suggests a complex interaction among benthic and demersal species sharing resources in the habitat, likely supported by a productive pelagic system.
