Urban green spaces (UGSs) are vital for enhancing urban ecological health and resident well-being. However, their diverse functions need to be balanced based on spatial limitations and varying stakeholder preferences. Integrated planning approaches are needed to exploit the multiple benefits of UGSs. This study introduces a multi-objective decision-support model designed to optimize UGS planning by simultaneously addressing carbon sequestration, ecological connectivity, and cost constraints. The model incorporates the non-dominated sorting genetic algorithm II to identify Pareto-optimal solutions for tailored decision-making strategies that balance different priorities. The model indicated that ecological connectivity can be improved by 7.57 % while meeting carbon-reduction and budgetary targets. The model effectively balanced trade-offs, underscoring the importance of both the quantity and strategic placement of green space. This decision-support framework empowers decision-makers to rapidly simulate and validate optimal scenarios, effectively balance competing objectives, and provide a scientific basis through verifiable feedback, ultimately promoting the development of sustainable urban environments.

Humans and other primates are capable of learning to recognize new visual stimuli throughout their lifetimes. Most theoretical models assume that such learning occurs through the adjustment of the large number of synaptic weights connecting the visual cortex to downstream decision-making areas. While this approach to learning can optimize performance on behavioral tasks, it can also be costly in terms of time and energy.

Freshwater lakes are increasingly subject to simultaneous nutrient enrichment and antibiotic pollution, yet the joint effects of these stressors on microbial network structure remain poorly characterized. This study examined the combined effects of nutrients and antibiotics on bacterial communities across eight bays in Erhai Lake, which were classified into high-, moderate-, and low-pollution zones. High-pollution bays (Haichao, Dongsha, and Shuanglang) recorded the region's highest nutrient concentrations, with chemical oxygen demand reaching 33.

Small cascade dams drive spatial divergence in the composition of dissolved organic matter (DOM) in local sediments. Taking Xixi River in the southeast of China, a representative small cascade-dammed watershed, as an example, this study explored the spatial variations of DOM components and its interactions with microbial communities under the influence of cascade dams. Results revealed that DOM composition differed significantly, i.

Microplastics and nanoplastics (MNPs) are common pollutants that engage with proteins, lipids, nucleic acids, and other biomolecules, damaging cell structure. This review goes beyond simply listing where MNPs are found to explore how they cause harm, detailing mechanisms such as oxidative stress, endocrine disruption, genotoxicity, protein misfolding, lipid membrane destabilization, and epigenetic changes. Propose an integrated mechanistic hypothesis connecting these processes via oxidative epigenetic feedback loops, size-dependent organelle targeting, and pollutant corona effects, with potential implications for cellular aging and transgenerational outcomes.

The One Health concept strongly brings into focus the important connections for human and ecosystem health. However, the incorporation of behaviour method guidelines in risk assessment and regulation/policy is not equal between human and ecological disciplines. A survey was conducted on the perceptions and role of behavioural (eco)toxicology in the protection of the human and ecosystem health.
