Summary: The climate variability hypothesis suggests that environmental thermal variation affects the thermal tolerance of species. In this study, we examined the thermal tolerance of 75 species of amphibian tadpoles from the Ecuadorian Andes and found that species from stable thermal environments have narrower thermal tolerance ranges than those from variable environments.

Summary: The study reveals a significant negative correlation between thermal tolerance and degree of subterranean specialization, with habitat temperature having only a marginal effect on lethal limits. Thermal variability plays a greater role than mean habitat temperature in shaping the thermal niche of subterranean species.

Summary: This study assessed the drivers of soil CO2 emissions in temperate forests in the Indian Western Himalayan Region. The results showed that soil temperature, maximum air temperature, and altitude positively influenced soil respiration, while vegetation abundance had a negative effect. This study provides valuable information for estimating the impact of climate change on soil carbon fluxes and developing carbon management policies for forest ecosystems.

Summary: This study investigated the longevity characteristics of thirteen fungi species, including yeasts, and found that lifespan is correlated with tolerance to oxidative stress in some yeasts, while mitochondrial activity alone cannot predict lifespan. The classification of strains showed that certain species have high mitochondrial activity, elevated resistance to oxidative stress, and elongated lifespan.

Summary: This study investigated the mitochondrial activity and biogenesis in Haberlea rhodopensis leaves during fresh, desiccated, and rehydrated states. The researchers found that unlike photosynthesis, mitochondrial respiration in the plant was immediately activated to levels comparable to fresh tissue upon rehydration. The abundance of transcripts and proteins involved in mitochondrial respiration and biogenesis remained consistent across all three states. The study also revealed the presence of alternative respiratory components and high uncoupled respiration capacity in desiccated tissue.

Summary: Paleoclimate reconstruction is essential for climate assessments, and it is important to benchmark the methodologies and proxy data used. Pseudoproxy experiments provide a transparent test bed for evaluating climate reconstruction methods, and this study develops a dataset that leverages proxy system models to make synthetic proxies more relevant to the real world. By conducting various experiments, a rich dataset (pseudoPAGES2k) is produced for many applications.

Summary: Despite overall warming, many regions in the Northern Hemisphere have been cooling in autumn. This cooling has led to an increase in the release of net CO2, as primary production decreased more than respiration in cooling areas and respiration increased more than production in warming areas. Despite opposite temperature trends, there has been a systematic increase in ecosystem carbon release across the Northern Hemisphere middle and high latitudes.

Summary: Research findings suggest that prenatal exposure to heat-calls affects mitochondrial function in zebra finch nestlings, particularly in high temperature environments. This discovery contributes to our understanding of acoustic developmental programming and avian strategies for heat adaptation.

Summary: The wave energy flux along the southern African coastline reaches extreme levels, impacting coastal communities and marine operations. A study using wave buoy data and wave models found significant seasonal and interannual variability in wave energy flux and direction. Climate modes such as the Southern Annular Mode (SAM), El Nino Southern Oscillation (ENSO), and the semi-annual oscillation (SAO) were assessed, with SAM showing the strongest overall relationship. Different climate modes and their combinations influenced the wave energy flux in different seasons.

Summary: In a future climate, the expansion of the Hadley cell and trade easterlies towards the poles is projected to impact the ocean and sea surface temperature (SST). This impact is expected to affect the large-scale SST variability, particularly in subtropical regions.

Summary: Comparing the thermal tolerance and performance of native and invasive species from varying climatic origins may explain why some native and invasive species can coexist. We found that the winter ant (Prenolepis imparis) is the native species best able to coexist with the invasive Argentine ant (Linepithema humile). These results suggest that partitioning based on differences in temperature tolerance promotes the winter ant's continued occupation of areas invaded by the Argentine ant.

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: Short-term temperature response curves of leaf dark respiration provide insights into how plant respiratory traits acclimate to changing environmental conditions. The study shows that thermal acclimation of leaf respiration is common in most biomes, with the threshold of respiration adjusting in response to warmer climates.

Summary: The dynamics of carbon dioxide fluxes in the high-altitude Alpine Critical Zone are complex due to the significant spatial heterogeneity and interannual variability caused by extreme climatic and environmental conditions. A study was conducted in the Nivolet plain, western Italian Alps, using in-situ measurements from 2018 to 2021 to analyze the relative importance of spatial and temporal variability of CO2 fluxes. The results showed that the variability of model parameters was larger across different years compared to different plots, indicating the importance of long-term flux monitoring to capture interannual temporal variability.
