Summary: The study provides evidence of the transfer of pharmaceuticals and endocrine disruptors through the aquatic-terrestrial habitat by emerging aquatic insects. Adult Trichoptera, an important food source for riparian predators, showed increased body burden of these contaminants. The transfer of these contaminants from aquatic primary producers to terrestrial predators may impact their physiology and population dynamics.

Summary: Tropical aquatic ecosystems are impacted by warming, leading to a decrease in connectivity between terrestrial and aquatic habitats, as well as a reduction in the flux of aquatic resources to terrestrial ecosystems and variable effects on the breakdown of terrestrial resources in aquatic ecosystems. This could potentially impact consumers in both ecosystem types and disrupt cross-ecosystem dynamics in an interconnected tropical landscape.

Summary: This Perspective presents an integrative framework to improve estimates of land-atmosphere carbon exchange by considering the accumulation of carbon in the landscape and its export through rivers. The framework uses the watershed as the fundamental spatial unit and integrates all terrestrial and aquatic ecosystems. The application of this framework can bridge the gap between land and atmosphere-based approaches and enhance communication and collaboration among research communities.

Summary: Species dispersal and resource spatial flows have significant impacts on the dynamics of connected ecosystems. This study investigates the role of subsidy stoichiometry in mediating the response of a meta-ecosystem to subsidy flows. The results demonstrate the potential for positive feedback loops and increased production at the meta-ecosystem scale through spatial complementarity. However, accentuating the stoichiometric mismatch between local resources and basal species needs can also have a negative impact on production.

Summary: The study investigated the variation of nitrogen components in different aquatic ecosystems and found that nitrogen removal occurred during water flow, with a reduction rate of up to 43%. The heterogeneity in eco-stoichiometric characteristics of nitrogen components was higher in ditches and ponds compared to rivers and reservoirs. Ditches and ponds showed stronger interactions between overlying water and sediment, with higher rates of denitrification and anaerobic ammonium oxidation. The findings emphasize the importance of focusing on the upper reaches of agricultural catchments for nitrogen removal and developing region-specific conservation strategies to mitigate nitrogen pollution and protect water resources.

Summary: Silver is a rare and precious metal found in minerals and released into the environment through weathering and mining activities. It also enters the environment through manufacturing and use of silver compounds. Silver nanoparticles have become a significant source of anthropogenic silver in the environment. Most silver in soil and water is sorbed to particles and precipitated as various compounds. Humans and animals can be exposed to silver through inhalation and consumption of contaminated food and water. Remediation of silver-contaminated soil and water can be achieved through immobilization and mobilization processes. This review provides an overview of the sources, geochemistry, health hazards, remediation practices, and regulatory mandates of silver contamination in complex environmental settings, and discusses knowledge gaps and research priorities.

Summary: This study develops a conceptual framework of lateral carbon transport (LCT), focusing on dissolved organic carbon (DOC) transport, and operationalizes it with a coupled terrestrial-aquatic carbon and hydrology model. The research finds that climate is the strongest driver of LCT-DOC, with precipitation positively related and temperature inversely related to LCT-DOC at continental scales. Plant traits, especially water use efficiency, also interact strongly with climate and have a measurable influence on LCT-DOC.

Summary: The environmental flow releases in lowland Australian rivers are currently timed to avoid high-carbon production on floodplains, while return flows are avoided to prevent introducing deoxygenated blackwater into the main channel. By studying blackwater flows in the lower Murrumbidgee floodplain, researchers found that floodplain vegetation contributes significantly to the blackwater dissolved organic carbon, which can in turn contribute to algal production and increase in-stream productivity.

Summary: Over the past 30 plus years, the Arctic has warmed at a rate of 0.6 degrees C per decade, leading to permafrost thaw and changes in hydrological and biogeochemical processes. Recent studies show increased inorganic nutrient fluxes in larger Arctic rivers due to warming-induced active layer expansion and newly exposed subsurface source areas. Headwater streams in the Arctic demonstrate the ability to control downstream transport of phosphorous, but not dissolved inorganic nitrogen.

Summary: Research in lowland headwater streams in the temperate northeastern United States found that CH4 ebullition rates exhibit temporal and spatial heterogeneity, increasing with temperature. Land use was found to have a weak predictive power on this heterogeneity, with factors like water depth and sediment organic matter content and quality playing a more significant role.

Summary: Fecal contamination is a major cause of global water quality impairment, and aquatic ecosystems play a crucial role in removing fecal contamination. Understanding the mechanisms of fecal contamination removal in river networks under different flow conditions is essential. A river network model, FrAMES-Ecoli, was used to study the removal of fecal indicator bacteria in New England watersheds during summers. The results showed that river networks can effectively remove fecal indicator bacteria, with removal rates influenced by hydrologic conditions, watershed size, and source distribution. These findings highlight the importance of considering river network removal in managing fecal contamination in downstream receiving waters.

Summary: River networks play an important role in biogeochemical processes of the earth system. Here the authors show that cumulative river network function increases faster than watershed size for many biogeochemical processes, particularly at higher river flow, indicating large rivers contribute disproportionately to network function in the Earth System.

Summary: The COVID-19 pandemic disrupted human activity, leading to changes in human-ecosystem interactions, known as the anthropause. The effects of the anthropause on ecosystem states and functions, as well as its feedback to human systems through ecosystem services, are still uncertain. This study proposes new investigation pathways using a disturbance framework to capture the effects of the anthropause through coordinated, long-term social-ecological research. Although it is still early to comprehensively evaluate these effects, case studies using long-term data show changes in air and water quality, as well as wildlife populations and behavior coinciding with the anthropause. These findings highlight the importance of long-term data in understanding the impacts of the anthropause and separating them from natural variation and long-term trends.

Summary: Households' willingness to pay for water quality improvements depends on the location of the improvements, with higher values found for improvements near their homes or iconic areas. This study found that there are specific areas in New England where improvements hold high value for individual households, which can be identified through map interactions. The results highlight the importance of considering spatial heterogeneity in willingness to pay for water quality improvements.

Summary: This study conducted an N mass balance in eight small reservoirs in coastal New England over annual time periods, considering both inorganic and organic forms of N. It found that small reservoirs have high capacity for dissolved inorganic N retention during low and moderate discharge, but are roughly in balance for DIN at higher discharge. Dissolved organic N was also evident during low flow late in the warm season. These findings highlight the importance of considering the transformations between inorganic and organic N when evaluating the effect of small reservoirs on TDN fluxes over seasonal and annual timescales.

Summary: Headwater stream networks contribute significantly to the terrestrial carbon dioxide flux due to turbulence and interaction with terrestrial environments. Measuring and scaling these emissions is challenging due to limited monitoring points. Our study found that the stream network had higher carbon emissions under high flow conditions compared to low flow conditions. Winter stream emissions accounted for a larger percentage of the forest net ecosystem exchange than in summer, highlighting the importance of considering flow regime in annual estimates of stream network emissions.
