Summary: Non-frugivorous waterbirds play a crucial role in dispersing weed plants over long distances, exchanging species between human-dominated and natural areas. The study demonstrates that about 92% of weed seeds are dispersed within the birds' activity area, while the remaining 8% reach other habitats, with 42% reaching moist environments suitable for weed establishment. This research emphasizes the significance of non-frugivorous birds in long-distance plant dispersal, an often overlooked mechanism in weed plant expansion studies.

Summary: Large gulls, including the little-studied Siberian migrant Vega gull, show consistent migratory patterns and behavior, with preference for coastal routes and long-distance flights between breeding and wintering grounds. Spring migration is faster and more synchronized than autumn migration, with higher flight altitudes and more day and twilight flights. Individuals exhibit strong site fidelity to their breeding and wintering sites, but show higher between-individual variation in autumn. Timing of spring migration is likely influenced by snowmelt, while the duration of migration windows could be related to flyway habitats. Ongoing environmental changes may impact migration timing and duration.

Summary: Biogeochemistry patterns in shallow lakes are influenced by both in-lake factors and watershed-level factors. The relative importance of these factors is not well understood. A study in Minnesota, USA demonstrated that lake size had the strongest influence on fish δC-13 ratios, while all agriculture in watersheds influenced fish δN-15 ratios. Water column TN and TP concentrations were influenced by the in-lake factor of ecosystem state, with lower concentrations in the clear state. Land use did not have a significant effect on TN or TP concentrations, likely due to the masking effect of ecosystem state.

Summary: We examined the factors of warm air temperatures, high solar radiation, and weak wind speeds in causing hypoxia in a shallow lake during a heat wave. By simulating dissolved oxygen concentrations in the lake's bottom water, we compared the concentrations in 2022 with the average concentrations of the past 30 years. Our findings showed that wind speeds had the greatest impact on hypoxia occurrence. Insufficient convection led to hypoxia when wind speeds were low, but there was no hypoxia when the wind speed matched the 30-year average. However, if solar radiation and air temperatures matched their respective 30-year averages, hypoxia did not occur even with low wind speeds. Therefore, we concluded that the combination of weak winds and either high solar radiation or air temperatures induced hypoxia during the 2022 heat wave.

Summary: This study assessed microplastic pollution in tropical shallow lakes and found different types and colors of microplastics in lake sediments. The results showed that environmental factors influenced the concentration of microplastics, but there was only a small difference between different regions. The study also suggested that pollution from sanitation, sewage effluents, and solid waste may be the main factors contributing to microplastic contamination.

Summary: Despite the negative impact of urbanization on biodiversity, urban areas provide unique opportunities for certain species. This study compares the movement behavior and habitat selection of Lesser Black-backed Gulls breeding in an urban colony and a coastal colony in north-west England. The results show that urban breeders prefer to forage in urban areas, while coastal breeders primarily forage in coastal habitats and avoid urban areas. Additionally, individual variations in habitat use were observed, which may have implications for management strategies. These findings highlight the link between nesting and foraging ecology and demonstrate that changes in food availability will affect gulls in coastal and urban areas differently.

Summary: Worldwide, water quality managers aim for a state of clear, macrophyte-dominated shallow lakes rather than turbid, phytoplankton-dominated ones. However, the concept of critical turbidity has been neglected in contemporary water quality models. In this study, an innovative graphical and mathematical model called GPLake-M was developed, combining the theories of critical turbidity and resource competition mechanisms. The results provide insights into the regime shifts in shallow lakes and can serve as a starting point for further research and model development.

Summary: Ecosystems under stress can exhibit abrupt and irreversible responses through tipping points. This study examines the possibility of bistability emerging through evolution by natural selection along resource gradients, using shallow lakes as an example. The model suggests that competitive asymmetries along opposing resource gradients may allow bistability to emerge, but under restrictive conditions, indicating the potential role of eco-evolutionary dynamics in alternative stable states.

Summary: While agricultural intensification is associated with lake eutrophication, the role of macrophytes and the effects of agriculture on shallow lakes in the global south remain less understood. A study on the Pampean region of Argentina found that submerged macrophytes, total nitrogen, and nearby agriculture were the main drivers of phytoplankton biomass in the shallow lakes. The conservation of submerged macrophytes and control of agriculture in riparian areas can help stabilize the shallow lakes and maintain a clear regime even in eutrophic conditions.

Summary: Analyzing the vertical distribution of nutrient salts in lakes and estimating the total mass of lake nutrients is important for the management and regulation of lake nutrient status. This study proposes algorithms for estimating the total masses of nitrogen (N) and phosphorus (P) per unit water column in shallow eutrophic lakes. Using Lake Taihu as an example, the study obtained the total masses of nutrients in the lake and discussed the performance of the algorithms. The results showed that the vertical distribution of nutrients in Lake Taihu followed a quadratic pattern, and the algorithms based on surface water quality indicators had good accuracy.

Summary: The study found that multitrophic richness had a stronger positive effect on multifunctionality than richness of single trophic groups. Removal of each single trophic group decreased the effect of multitrophic richness on multifunctionality. Larger predatory vertebrates and primary producers had stronger positive effects on multifunctionality, while the richness of basal trophic groups indirectly contributed to increasing multifunctionality through fueling large-sized predators.

Summary: Endozoochory by waterfowl is important for a broad range of angiosperms, most of which lack a fleshy fruit. This dispersal function contributes to the formation and maintenance of plant communities and may allow range shifts for plant species under global change. However, our current understanding of what seed or plant traits are important for this dispersal mechanism, and how they relate to variation in waterbird traits, is extremely limited.

Summary: Coastal wetlands are valuable aquatic ecosystems with high productivity that provide important services, but are at risk of salinization due to predicted rise of sea level and freshwater extractions. Salinization may shift microbial activity from heterotrophic bacterial-dominated processes towards archaeal-dominated processes, influenced by factors like nitrogen concentration, salinity, and virus abundance. More research is needed to accurately predict future scenarios in coastal wetlands.

Summary: Animal-borne bio-logging devices are commonly used on seabirds to study their behavior and physiology, as well as their interactions with the marine environment. Assessing the negative impacts of such devices on the individuals carrying them is crucial for improving data quality and animal welfare. In this study, we examined the effects of thoracic-harness attachments on the breeding performance and return rates of Great Black-backed Gulls. The results showed that the tagged individuals had lower egg hatching numbers and success rates compared to control groups, and the harness attachment potentially caused the death of one individual. Caution is advised when using harness-mounted devices on Great Black-backed Gulls.
