Summary: The study found that the export of nitrogen and phosphorus from the perhumid coastal temperate rainforest of northwestern North America is influenced by seasonal and stormflow events, showing a pulsed nature in the magnitude and species of nutrients exported.

Summary: The study revealed the significant carbon stocks in Mexican wetlands, with unprotected swamp forests and marshes containing substantial peat deposits, while grazed areas showed lower carbon storage effectiveness. Differences in carbon storage among wetland vegetation types in different regions highlight the need for region-specific government policies to protect coastal wetland carbon stocks.

Summary: The study highlights the lack of understanding of multiple stressors on urbanized Andean streams, where urbanization mostly impacts stream ecosystems through water-chemistry and physical-habitat stressors, with ecosystem functioning being more affected than structural attributes. It suggests that managers should focus on reducing important stressors rather than investigating complex stressor interactions, and that stream biomonitoring programs would benefit from a combination of structural and functional indicators in assessing anthropogenic effects.

Summary: Recent studies have mostly focused on the impact of large tropical cyclones on shorelines, disregarding the effects of less intense but more frequent events. This study analyzes the influence of offshore tropical storm Melissa on groundwater along the North America Atlantic coast. The findings show that Melissa led to a significant increase in groundwater level and specific conductivity, with a longer recovery time for conductivity. The study suggests that the increasing frequency of moderate storms will have a significant ecological impact on vegetated shorelines.

Summary: This study analyzed the effects of sugarcane cultivation on methane fluxes and concentrations in tropical streams in Southeastern Brazil, finding higher methane fluxes and concentrations during the summer and in streams with preserved catchments. Water chemistry factors such as dissolved oxygen, dissolved organic carbon, water velocity, and conductivity were found to influence methane concentrations in the studied streams.

Summary: This study evaluated the changes in hydrological and sediment connectivity in the Santa Cruz catchment in Mexico over a period of 42 years and projected these changes under a climate change scenario. The results showed that changes in land use/cover and expected climate change would modify hydrological and sediment connectivity. Under future conditions, there is likely to be an increase in runoff and sediment transport, which will impact soil erosion and vulnerability to flooding.

Summary: Urbanization has a significant impact on the water quality of urban streams, particularly in areas closer to the city center. During the summer season, when water levels and discharges are low, there is a significant increase in the concentration of metals/metalloids in the water. Continuous monitoring of urban streams, especially during warmer seasons, is recommended.

Summary: Climate change leads to more frequent and intense floods in agricultural regions of southern Wisconsin. During floods, concentrations and fluxes of CO2 and CH4 in streams are higher, likely due to flushing of gases from soils and respiration of organic matter.

Summary: Coastal ecosystems depend on local marine productivity and the subsidized productivity of fluvial systems. Terrestrial subsidies in insular ecosystems represent a relevant source of nutrients for many coastal communities, so variations in these contributions can cause negative impacts. Human activities such as deforestation can lead to increases in nutrient inputs to coastal ecosystems through rivers, resulting in changes in microalgal assemblages and vegetation.

Summary: Medicanes, or Mediterranean hurricanes, are mesoscale cyclones that have similar characteristics to tropical cyclones. They pose significant threats to islands and coastal areas within the Mediterranean Sea. This study investigates the oceanic response to these extreme events under present-day and future climate conditions, using a coupled hydrodynamic-wave model and synthetic data sets from global climate models. The results provide valuable information for coastal hazard assessment in the Mediterranean region.

Summary: Nutrient runoff from agriculture practices can have detrimental effects on waterway health and the environment. A systematic literature review was conducted to identify and evaluate nutrient runoff mitigation strategies based on their environmental benefit, implementation cost, and practicality. The review highlighted research gaps and barriers to the widespread implementation of these strategies, such as a lack of literature on nutrient runoff mitigation and reluctance from agricultural landowners to adopt policies without incentives. The synthesis of review data facilitated the development of a comprehensive nutrient runoff decision-making framework for policymakers to implement site-specific strategies.

Summary: Seabird colonies release high concentrations of nutrients, metals, and contaminants through their wastes, impacting the chemistry of lentic water bodies. Storm-petrels significantly increase metal concentrations in the affected sites, suggesting their role as biovectors of environmental contamination.

Summary: This study analyzed the effects of seasonal estuarization on the trophic structure of estuarine and neritic ecosystems, revealing that the transfer of organic matter and energy between ecosystems increases the complexity of the trophic structure of neritic ecosystem.

Summary: Research shows that climate change could make the current network of marine protected areas in 12 nations in the Western Indian Ocean ineffective in supporting conservation and socioeconomic outcomes. Most of the coral reefs and marine protected areas in countries at the highest risk of food insecurity are likely to experience significant biodiversity losses.
