Summary: A field experiment was conducted to investigate the effects of intercropping systems on soil biota. It was found that intercropped maize soils had increased complexity and robustness of soil networks, while densities of plant parasitic nematodes and β-glucosidase activity were reduced. Intercropped soybean soils had lower C availability, but showed an increase in saprophytic fungi and plant parasitic nematodes compared to monoculture soils.

Summary: This study compared the grain filling dynamics, source-sink characteristics, and quality-related traits of rice under different natural field temperature conditions. The findings suggest that high natural field temperature during the reproductive stage negatively affects rice quality by increasing chalkiness and protein content, and decreasing starch content and grain-filling duration.

Summary: This study proposes a technical analysis framework for the source-sink process of microplastics based on the watershed-estuary-offshore system and investigates the impacts of human activities and hydrologic conditions on microplastic distribution patterns in Laizhou Bay. It concludes that river input is the main pathway for microplastics in coastal areas to enter the sea and that population clusters and urbanization play a significant role in microplastic emission hotspots. The study also establishes a model to simulate the transport of microplastics in the bay, confirming that river inputs are an important source.

Summary: Carabids beetles are important biocontrol agents of weeds, but it is difficult to predict their consumption levels and regulation of weed seeds. Olfactory cues from predators or potential competitors can influence the selection and consumption of food resources by foraging individuals. Identifying and understanding the factors that drive the seed foraging behavior of carabid beetles is essential for predicting consumption levels in different carabid communities and improving weed regulation.

Summary: This paper presents a classification mapping routine to classify the Danish stream network into an established Groundwater-surface water interaction (GSI) typology framework. The results show that about 85% of Denmark's streams are connected to groundwater, with approximately equal portions in sandy and clayey areas. The maps will assist policymakers in controlling water and pollutant transfer from the uplands to streams to attain good environmental status for surface and groundwater bodies.

Summary: This study developed methods to estimate referral and prehospital time in rural districts of low and middle-income countries, and found that despite efforts to strengthen the health system, referral time remained the main barrier limiting the number of referrals. The addition of new referral centres is estimated to triple the population living within 2 hours from a centre with better emergency care capacity and nearly double the number of expected referrals.

Summary: Organisms with complex life cycles have populations that occupy different habitats at different stages, creating demographically open populations. The dynamics of these populations depend on the occurrence and timing of stochastic influences relative to density dependence. However, understanding these dynamics has been challenging, especially in the face of climate warming. In this study, a density-perturbation experiment was conducted using stream caddisflies, and it was found that density dependence occurs in the larval stage, offsetting variability associated with dispersal and driven by food resource abundance. The results also highlight the complementary nature of stochastic and deterministic influences on open populations.

Summary: This study conducted an analysis of stream macroinvertebrate communities under different stressor gradients using trait-based approaches and found that anthropogenic stressors have stronger effects on community composition compared to natural stressors. The movement of communities along multiple axes in trait space is likely driven by limited adaptation to these novel stressors.

Summary: The small population paradigm suggests that reduced genetic variation leads to limited phenotypic variation, affecting population resilience and adaptation. However, recent evidence challenges this paradigm, indicating that mechanisms independent of genetic variation may also play a role. In aquatic ecosystems, large-scale empirical examples are scarce.

Summary: Habitat modification and mammalian predation have different impacts on the range contraction of the threatened New Zealand riverine duck. Mammalian predation is the main driver of the catastrophic declines of this species, while habitat modification also contributes to its decline. The study identifies potential habitat areas for conservation of the riverine duck outside its current range, provided mammalian predator control is implemented.

Summary: Amphidromy is a unique life-history strategy of certain fish species where they spawn in fresh or brackish water, and then newly hatched larvae disperse to the sea where they develop for a brief period. They later return to freshwater as juveniles, grow and mature, and then spawn. The six amphidromous species from the Galaxias genus in the Southern Hemisphere are important for recreation, culture, and economy, particularly because their juveniles are harvested. However, the declining population and lack of important demographic information raise concerns about their management.

Summary: The study found that quantifying the body size-specific habitat use of vulnerable species is crucial for accurately evaluating population health, identifying the effects of anthropogenic stressors, and directing effective habitat restoration. The total biomass of large kokopu was most affected by pool volume and forest cover, while the biomass of small kokopu was influenced by substrate size, bank cover, and pool volume. The study highlights the importance of considering the ontogenetic shift in species' habitat use.

Summary: Scientific support can improve conservation and community livelihoods by assisting Indigenous peoples and local communities (IPLC) in customary environmental management. This study developed a demographic model to help Ngai Tahu, a Maori tribe in New Zealand, manage a culturally important population of Black Swans. The model highlighted the importance of monitoring and limiting adult and subadult swan mortality for population and egg harvest sustainability, and suggested that closer monitoring of swan mortality could enhance Ngai Tahu's ability to practice customary harvest.
