Summary: Understanding the relationship between behavioural buffering of temperature change and organismal fitness is crucial in the era of human-driven climate change. This study investigated how thermal landscapes, physiological performance, and behaviour interact and shape fitness in the southern rock agama lizard. The results showed that male lizards in territories with low thermal quality spent more time compensating for sub-optimal temperatures and displayed less. Moreover, the display rate was positively associated with lizard fitness, indicating that engaging in thermoregulatory behaviour may incur opportunity costs as climate change progresses.

Summary: As climate change progresses, understanding how animals respond to shifts in their local environments is crucial. Changes in microbial communities that live in and on host organisms are part of this response. We investigated the effects of shifting climates on the gut microbiome of slender anole lizards through field and laboratory studies, including transplants to warmer islands in the Panama Canal. We found that slender anole microbiomes remained stable in response to short-term warming but may be sensitive to sustained climate anomalies, such as droughts. These findings have important implications for a species considered highly vulnerable to climate change.

Summary: Anthropogenic climate change poses a significant threat to biodiversity, with extreme temperature events increasing in frequency, duration, and intensity. While the effects of climate extremes on insects have been well-studied, spiders and other arthropods have received less attention. This paper discusses spider responses to extreme temperatures and identifies important knowledge gaps that need to be addressed to understand their vulnerability to climate change.

Summary: The research began with explaining the high level of aerobic metabolism in mammals and progressed to investigate the role of membrane lipids in metabolism. It was found that the increase in aerobic metabolism in mammals is driven by increases in mitochondrial volume, membrane densities, organ size, and changes in enzyme activity. The increase in energy production is matched by increases in energy use, notably driven by increases in H+, Na+, and K+ fluxes. Maintaining Na+ gradient across cell membranes depends on an increase in sodium pump molecular activity rather than an increase in sodium pump number, coupled with an increase in highly unsaturated polyunsaturated fatty acids (PUFA) in membranes.

Summary: In this study, we examined the effects of a 2 degrees C-warmer climate on the thermal traits of Zootoca vivipara lizards. We found that adults exhibited plastic changes in dorsal coloration and preferred temperature in warmer climates, and these changes were not in line with the selective gradients. Juvenile lizards, on the other hand, showed darker coloration in warmer climates, either through plasticity or selection, and this effect was further enhanced by intergenerational plasticity. The study highlights the importance of considering both plasticity and selection in understanding adaptation to climate change.

Summary: This study aims to characterize the energy transfer from parental organisms to offspring in Brazilian Guitarfish through the analysis of energy markers in parental fluids. The results indicate that these markers are being made available to the offspring, possibly as complementary sources of energy. This research sheds light on the metabolic dynamics during reproduction stage in Elasmobranchs.

Summary: The different planes of pre- and postweaning nutrition have effects on prepubertal serum leptin concentrations, LH profiles, and age at puberty in Holstein heifers. Higher preweaning nutrition levels can increase leptin concentrations, while higher postweaning nutrition levels may lead to an earlier onset of puberty.

Summary: CRISPR/Cas9-based homing gene drives are a potential new approach to mosquito control. In this study, researchers successfully generated transgenic Ae. aegypti lines expressing Cas9, which significantly biased the inheritance of an sgRNA-expressing element. The sds3G1-Cas9 isolate showed the highest average inheritance, indicating its potential for driving the spread of the targeted element more efficiently.

Summary: This meta-study found that cardiac capillary numerical density and mitochondrial volume density decrease with increasing body mass. The scaling trajectories suggest quantitative matching between the supply and consumption of oxygen in the heart, supporting the economic design at the cellular level. However, the exponent for the maximum external mechanical power of the cardiac tissue decreases at a slower rate, implying a declining external mechanical efficiency of the heart with increasing body mass.

Summary: The study examines the growth rate and mass changes during larval stages and metamorphosis across various taxa. It finds support for Werner's assumption regarding growth rates but contradicts the assumption that body size remains constant during transitions. The research suggests that mass changes profoundly affect the timing of transitions, emphasizing the need to consider the impact of mass loss or gain on fitness.

Summary: Climate change presents challenges for plants due to increased temperature exposure. Phenotypic plasticity plays an important role in plant responses. Different traits show different responses to temperature. Temperature affects plasticity in germination, leaf, physiology, and reproductive traits, and plasticity variation among family lines is related to fitness.

Summary: This study investigates the effects of climate warming on the trade-off between seed size and number in an alpine plant. The results show that warming during parental growth reduces both seed size and number, but does not affect germination. This highlights the detrimental effect of warming on parental fitness and the potential risk of climate change for alpine plant communities.

Summary: Constraint-based explanations have dominated theories of size-related patterns in nature. However, we propose a new theory that predicts metabolic allometry arises as a consequence of the optimization of growth and reproduction to maximize fitness within a finite life. Our theory is free of physical geometric constraints and suggests that metabolic allometry can be explained without invoking traditionally assumed constraints.

Summary: Dispersal plays a crucial role in individual fitness, population dynamics, and range expansion. The spatial sorting of phenotypes at range edges and invasion fronts can lead to changes in morphological traits related to dispersal. However, different study systems exhibit varying responses to spatial sorting, and separating spatial sorting from natural selection and population dynamics is challenging.

Summary: Froese and Pauly argue that our model contradicts the observation that fish reproduce before their growth rate decreases. Kearney and Jusup show that our model incompletely describes growth and reproduction for some species. Here, we discuss the costs of reproduction, the relationship between reproduction and growth, and propose tests of models based on optimality and constraint.

Summary: Incubation temperature has lasting effects on growth, locomotor performance, and metabolic rate of skink offspring. Cool and hot incubation temperatures result in faster growth and larger maximum size, while hot incubation temperatures reduce locomotor performance. Effects on metabolic rate are present in sub-adults, with higher rates in cool-incubated lizards. Additionally, cool and hot incubation treatments result in shorter sperm midpieces and heads.
