Summary: The Permian Period experienced unprecedented Earth system changes, transitioning from icehouse to greenhouse conditions and facing two biocrises associated with volcanisms. Seawater Sr isotope records can illuminate the Permian Earth system evolution, but face issues such as low resolution and potential diagenetic alteration. New research suggests that changes in hydrothermal input, rather than continental weathering intensity, may have been the primary driver of the observed variations in Permian seawater 87Sr/86Sr ratios.

Summary: Predicting microbial community behaviors relies on understanding their interactions. This study investigated interactions among four bacterial species and validated model predictions through experiments. However, the growth medium had inhibitory effects on Comamonas testosteroni, and metabolites secreted by Agrobacterium tumefaciens and Microbacterium saperdae shortened its lag phase.

Summary: The Dolomites is a significant region for studying the evolution of shallow-marine ecosystems during the end-Permian mass extinction. By using strontium isotope stratigraphy, the correlation between the Dolomites and the Meishan section can be established, contributing to the understanding of the biological crisis that occurred.

Summary: The Rhynchonellida, a group of brachiopods, showed increased lineage richness in the Early and early Middle Triassic with changes in shell size and development of ornamentation. The study suggests that paedomorphosis might have been a survival strategy for certain genera to thrive in the harsh environment after the P/Tr extinction.

Summary: This study evaluated the empirical support for environmental stress models (ESMs) and found that consumer pressure on prey typically decreases with increasing environmental stress (consumer stress model; CSM), while prey pressure on consumers (prey stress model; PSM) occurs less frequently. This contrasts with a prior survey, suggesting that consumers are generally more suppressed by stress than prey. Therefore, increased climate change-induced environmental stress is likely to reduce the impacts of consumers on prey more often than the reverse.

Summary: Recent research has shown that changes in resource availability can impact a consumer's thermal performance curve. When resources decline, the optimal temperature and breadth of thermal performance also decrease, increasing the risk of warming. This study investigates how temperature affects consumer-resource dynamics and the potential for changes in the consumer's thermal performance curve to alter extinction risk.

Summary: The turnover of microbial communities is influenced by local and regional factors. Local factors shape community assembly through biological interactions and the environment, while regional factors affect microbial dispersion patterns. This study investigated the turnover processes of three microbial subcommunities in a tropical freshwater reservoir cascade during dry and rainy seasons. The results showed that both local and regional factors played a role in community composition, with different influences in each season.

Summary: This study investigates the interactions between phytoplankton and bacterial communities in three lakes in southwestern China. The results uncover the influence of environmental conditions, phytoplankton community structure, resource-use efficiency, community turnover, and microcystins on bacterial community diversity and composition.

Summary: In a global society, there are various land use patterns, inequality, and movement of people and goods, raising concerns about the future sustainability of the human population and the natural environment. Inequalities in resource access and differences in technological progress impact land management outcomes and social behaviors within the global society.

Summary: The redox chemistry change in ancient oceans has had a significant impact on the evolutionary trajectories of animals. Uranium isotopes in marine carbonate sediments have been used to quantify the oxygenation state of the oceans throughout geological history. However, diagenesis processes can introduce uncertainties in these measurements. This study examines the potential of using articulate brachiopod shells as diagenetically resistant materials to accurately record the ancient seawater conditions. Results show that approximately 53% of the shells preserve the primary seawater signals. The study also reveals four episodes of expanding marine anoxia during the Permian, which are temporally correlated with periods of volcanism. The last two anoxic events coincide with or precede the end-Guadalupian and end-Permian mass extinctions, confirming the importance of marine anoxia in driving marine animal extinctions.

Summary: The study utilized ecological niche modelling to investigate the effects of climate change on passerine species in the Himalayas, finding significant turnover between the Last Interglacial Period and the Last Glacial Maximum. The statistical analyses of climatic variables revealed increased variability during the Last Interglacial Period, potentially causing community turnover. Furthermore, the study suggests that dramatic historical climate change could overcome the buffering effect of elevational heterogeneity in tropical mountains, emphasizing the importance of considering past climate change in understanding biodiversity patterns.

Summary: Predicting food web structure in future climates is a key goal of ecology, but requires a solid understanding of the factors shaping current food webs. The relationship between the number of links and species in food webs is still poorly understood, with some interactions being 'forbidden' and potentially impacting structure. Accounting for these 'forbidden interactions' can constrain the feasible link-species space, with food webs distributed throughout this space based on shared biotic and abiotic features. This study offers new insights into the factors determining this fundamental aspect of food web structure.
