Summary: The study investigated the competition between microbial invaders and resident microbes under different environmental conditions, finding that invaders were more likely to colonize a toxic medium in the presence of resident communities, while invasive species that could survive alone had a higher success rate in benign environments when residents were absent. Through experiments, it was shown that early colonists may exclude future invaders through a priority effect.

Summary: This study identifies pH as a key factor that influences the interactions between nectar-colonizing microbes, plants, and pollinators, thereby exerting important ecological and evolutionary effects on ecological communities. Field and laboratory experiments demonstrate the significance of pH-driven priority effects in species competition and evolution, and a field experiment reveals the functional consequences of nectar pH for plant reproduction.

Summary: The landscape genetic structure can reflect the rapid genetic adaptation of early colonist lineages to local conditions during population assembly, resulting in an evolution-mediated priority effect that limits the establishment opportunity for later-arriving lineages.

Summary: The study found that local priority effects promote the survival of rare species, leading to higher metacommunity diversity and significant disparities in richness among evolutionary lineages. However, classic macroevolutionary patterns of niche incumbency are not influenced by local priority effects.

Summary: Recent studies show that ecological and evolutionary processes can often interact; however, our understanding of evolution in multi-species communities is still lacking; focusing on interactions between evolutionary biology and community ecology processes can explore eco-evolutionary dynamics in multi-species communities.

Summary: Changes in land use and agricultural intensification have negative impacts on biodiversity and ecosystem functioning of small water bodies. A study in northeastern Germany found that land-use type affects the structure of active bacterial, archaeal, and eukaryotic communities in kettle holes, but does not significantly impact gene expression patterns. This suggests a high level of functional redundancy across the communities. The study highlights the importance of considering the effects of surrounding landscape on water bodies for sustainable management and biodiversity conservation.

Summary: The study demonstrates stabilizing single-atom catalysts on tungsten carbides for efficient oxygen evolution reaction, achieving low overpotential and high turnover frequency due to the unique structure of tungsten carbides. The application of inexpensive and durable WCx supports opens up a promising pathway to develop further single-atom catalysts for electrochemical catalytic reactions.

Summary: This study introduces an evolutionary model based on hypergraph theory combined with aging effect to reflect the temporal dynamics of citation behavior. The empirical analysis shows that the attraction of early publications decays exponentially, and the aging effect significantly influences the description of collective citation patterns.

Summary: The arrival order of species, known as the priority effect, is important for determining the outcome of their interactions. This study uses a metacommunity model to demonstrate that the specific mechanisms underlying priority effects influence biodiversity patterns and the homogenizing effect of high dispersal. Trait-dependent priority effects can significantly reduce the effect of dispersal on biodiversity, highlighting the importance of considering these mechanisms in understanding patterns of biodiversity.

Summary: Understanding the response of biodiversity to environmental changes requires linking local and regional ecological and evolutionary processes. In this study, we integrated evolution and mutualistic coevolution in a model of metacommunity dynamics and conducted numerical simulations to examine the effects of coevolution on species distribution and persistence. Our results demonstrate that coevolution and species richness synergistically shape distribution patterns by enhancing colonization and reducing extinction in metacommunities. Coevolution increases trait matching among mutualists at the landscape scale, counteracting local maladaptation and facilitating colonization and range expansions. Furthermore, coevolution buffers the effects of environmental changes, preventing species extinctions and metacommunity collapse. These findings elucidate the mechanisms by which coevolution promotes persistence under environmental changes, particularly in diverse systems with landscape connectivity.

Summary: This paper investigates a cooperative optimization framework for eco-driving and signal priority for freight vehicles on signalized arterial roads. By optimizing speed trajectories and signal timing, the goal is to minimize fuel consumption of freight vehicles and queueing delay of passenger vehicles at intersections, with the aim of achieving freight-priority. A sub-optimal strategy is proposed to address the non-convex optimization problem caused by constraints from queues and traffic signals. Comparison studies show significant improvement in traffic efficiency and fuel economy with faster calculation.

Summary: This study investigates the mechanisms governing the recovery of aquatic macroinvertebrates following flood disturbance by combining field surveys with a field experiment. The results show that beta diversity actually decreases among natural habitats over time after the flood or the creation of ponds, contrary to expectations. Flood heterogeneity and spatial scale differences between experimental ponds and natural habitats constrain the balance between deterministic and stochastic processes driving the convergence of assemblages over time.

Summary: The emergence of eco-philosophy and applied environmental ethics from the concepts about nature and the environment has led to new currents of thinking supporting pro-ecological movements. Research shows the importance of interdisciplinary dialogue, training philosophical consultants, and promoting ecological concepts for developing sustainable communities.

Summary: In hypersaline environments, microbial communities use DNA primarily as a phosphorus source, requiring other sources of carbon and nitrogen for substantial growth. The taxonomic composition of eDNA in the water column changes depending on the availability of inorganic phosphorus or supplied DNA, indicating preferential uptake of eDNA from specific organismal sources. Substantial shifts in the taxonomic composition and diversity of microcosm communities occur due to preferential eDNA consumption and differential growth under various nutrient availability regimes, suggesting microbial community assembly in salterns is driven by available resources, including eDNA.
