Summary: Understanding the effects of historical climate variability on current climate differences and their impacts on soil bacterial communities is crucial for evaluating the feedback of terrestrial biosphere to global climate change. Our study shows that the influence of historical climate fluctuation can enhance stochasticity and reduce community dissimilarity, while current climate differences can lead to pronounced divergence between communities. Ignoring the impact of prior climate variability may result in underestimating the influence of current climate differentiation on community dissimilarity and assembly stochasticity.

Summary: This study used a geological chronosequence across the Hawaiian Islands to examine the changes in ecological communities with community age. By sampling arthropod and plant communities and analyzing their interactions, the study found that the number of interactions, ratio of plant to arthropod species, and interaction evenness increased significantly with community age. Additionally, the index of specialization had a curvilinear relationship with community age. These findings indicate that younger communities have fewer but stronger interactions, while older communities become more diverse and even.

Summary: This study investigates the differences in genetic and demographic dynamics, as well as the effects on population survival, under two types of stochasticity: demographic stochasticity and environmental stochasticity. The research shows that population survival probability declines sharply with stronger stabilizing selection under demographic stochasticity, but declines more continuously when environmental stochasticity is strengthened. However, the genetic variance that confers the highest population survival probability differs little under the two types of stochasticity.

Summary: The dynamics of habitat selection in response to predators is a complex function of predator identity, density, richness, species composition, and patch spatial context. Prey show varied responses to specific predators or combinations of predators, resulting in distinct community composition and higher beta-diversity. Non-consumptive effects of predators can dramatically impact individuals, populations, and communities, with habitat selection playing a key role in prey responses.

Summary: The finding that adaptive evolution can often significantly impact ecological dynamics challenges traditional perspectives that ignore evolution in community ecology. This study proposes that evolution frequently alters both local and regional processes of community assembly, showing how adaptation can greatly affect community composition and that this is influenced by regional factors such as environmental heterogeneity and spatial structure.

Summary: Biotic interactions play a major role in microbial diversity, but they have not been adequately quantified, leading to unexplained residual variation in microbial biogeographic studies. In this study, a holistic approach was proposed to understand the importance of inter-domain interactions in shaping microbial diversity by considering community-level characteristics. The research found that eukaryotic characteristics were better predictors of bacterial diversity indices and community structure compared to environmental and spatial variables alone. The study also highlighted the significance of non-grazing interacting processes in shaping bacterial diversity and community assembly.

Summary: The study of deep-time ecological dynamics shows that mammalian ecological assemblages undergo long periods of functional stasis despite high taxonomic volatility. Higher functional richness and diversity promote the persistence of functional faunas, safeguarding functional diversity may enhance the persistence of ecosystem functioning in the face of future disturbances.

Summary: The study investigated the microbial assembly pattern in petrochemical sludge, revealing different strategies for the abundant and rare operational taxonomic units. Abundant OTUs were more influenced by deterministic processes, while rare OTUs were more affected by weak selection. The results provide insights into the adaptation of bacteria and archaea in petrochemical wastewater treatment.

Summary: Marine microbial communities assemble along sediment depth gradients, affected by various factors. Archaeal community assembly is determined by determinism, while bacterial community assembly is dominated by stochasticity. Rare taxa play a significant role in community stabilization, suggesting the importance of studying benthic microbial interactions in the bottom sediments.

Summary: Habitat degradation is expected to alter community structure and ecosystem functions, affecting biodiversity. Positive species covariance and community stability were found to be impacted by nutrient levels and habitat types. Ecological stochasticity was higher in natural sites compared to modified habitats, suggesting deterministic processes could control community composition.

Summary: Managing and engineering microbial communities requires the ability to predict their composition. While little work has been done on predicting compositions on evolutionary timescales, this study shows that community composition typically changes during evolution, but the composition of replicate communities remains similar. These changes were also predictable, suggesting that it may be possible to forecast the evolution of microbial communities even on long timescales.

Summary: The study examines the economic effects of lockdowns in different regions through supply chains, finding that upstreamness, intensity of loops, and supplier substitutability largely determine the economic impact of the lockdown in a region. The economic recovery after lifting a lockdown varies depending on whether it is done alone or with another region closely linked through supply chains. Inter-region policy coordination is proposed to reduce economic loss due to lockdowns.

Summary: Reputation serves as a powerful mechanism for enforcing cooperation among unrelated individuals through indirect reciprocity, but faces challenges such as private assessment disagreement, noise, and incomplete information. The study suggests that a social norm should meet certain conditions to penalize its close variants, and the appreciation of a well-reputed player's donation to an ill-reputed co-player by other society members plays a crucial role. The continuum formulation proposed demonstrates how indirect reciprocity can operate beyond the binary distinction between good and bad, even in the presence of inhomogeneity, noise, and incomplete information.

Summary: This study investigates the longitudinal dynamics of development cooperation at the global level, with a focus on aid flows. The analysis of aid data from 1970 to 2013 reveals a persistent structure of aid networks, consisting of a small number of major donors and a large number of globally connected recipients. This challenges the efficacy of aid reform efforts to substantially change the global aid flow pattern.

Summary: Group structure has a profound impact on social interactions and cooperation behaviors. This study explores the interaction between population structure and reciprocity in the evolution of cooperation. By using a game-theoretic model, the researchers find that the effect of population structure depends on the benefit of cooperation, with group-structured populations being more cooperative when the benefit is small and well-mixed populations being more cooperative when the benefit is large.

Summary: To prevent the spread of COVID-19, many governments have imposed lockdowns, resulting in economic stagnation. This study examines the economic effects of lockdowns in multiple regions and finds that coordinating the timing of lockdowns leads to smaller economic losses. Furthermore, the benefits of synchronous lockdowns are greater when regions are connected through more supply-chain links. These findings highlight the importance of policy coordination across regions and countries during lockdowns.

Summary: Centrality, a fundamental concept in modern network theory, quantifies the importance of individual nodes through various measures. This paper introduces a classification system for parametrized centralities and identifies a new type of centrality called ground-current centrality. The ground-current centrality differs significantly from other centralities and demonstrates consistent performance in preserving rank order and centrality value distribution across different network architectures.
