Summary: Seabirds breeding on remote islands form dense nesting colonies, with their activities affecting soil invertebrates in different ways. The impact of nesting varied between taxa depending on life history and seasonality, reflecting a dynamic relationship influenced by the hyper-abundance of nesting seabirds.

Summary: This study quantifies the river radium inputs into the Arctic Ocean for the first time and improves the estimates for this region. Through lab experiments and data from major rivers around the world, it is found that rivers are an important source of radium to the Arctic Ocean. Understanding river radium inputs is crucial for studying changes in biogeochemically important element fluxes as climate change and Arctic warming continue.

Summary: Understanding the relationship between biodiversity and ecosystem function and how it is influenced by the Earth's surface is a central objective in ecology. This study used high-resolution habitat mapping and field sampling to investigate the connections among geophysical habitat structure, invertebrate communities, and secondary production in two North American riverscapes. The results show that sediment size patterns have a strong influence on invertebrate assemblages, and these relationships drive positive connections between biodiversity and secondary production.

Summary: Marine-derived macrophytes, such as sea wrack, can be used as habitat or food by terrestrial invertebrate fauna in sandy beach systems. This study aimed to investigate the relationship between landed sargasso and terrestrial invertebrate communities, as well as the potential use of sargasso as habitat or food. Surveys and experiments conducted in Southeast Florida showed that the quantity of sargasso had a more significant effect on invertebrate composition than location.

Summary: This study investigated the contribution of coastal terrestrial groundwater discharge and porewater exchange to dissolved carbon export in a tropical estuary in China. It was found that terrestrial groundwater discharge had a significant impact on DIC export, while porewater exchange played a crucial role in delivering DOC to the ocean. Both pathways contributed a large amount of dissolved carbon export to the coastal water, highlighting the importance of assessing different SGD pathways in understanding terrestrial solute fluxes.

Summary: The study suggests that sulfur-normalized Hg concentrations are the best proxy to assess Hg anomalies in Upper Ordovician sediments of the Yangtze Platform. The findings show that the dominant source of Hg in the study sections is terrigenous, rather than volcanic.

Summary: This study quantified the contribution of terrestrial invertebrates to tropical lakes by setting up pan traps in six lakes located in the Atlantic rainforest in south-eastern Brazil. The total abundance, biomass, and richness of insect orders were examined. The distance from the forest and the morphometric characteristics of each lake were measured to assess their influence on terrestrial invertebrate inputs.

Summary: Stable isotopic compositions of 25 rivers in Thailand were analyzed monthly from 2013 to 2015. The study found that monsoon precipitation significantly influences river isotopes, leading to spatial and temporal variations in isotopic compositions among different geographical regions. This research can be used to explore hydrological interactions in other tropical river basins.

Summary: Terrestrial inputs of dissolved organic matter (DOM) can stimulate microbial growth and increase food availability for zooplankton, but might decrease the content of eicosapentaenoic acid (EPA) in particular organic matter (POM), thereby reducing food quality and biomass of filter-feeding zooplankton.

Summary: By analyzing the elemental concentration and stable isotope composition of sub-surface sediments from 18 wetlands in eastern Australia, the study found that the variability in the geochemical organic matter data is mainly explained by geographic differences in catchment vegetation cover and the balance of terrestrial versus aquatic organic matter input to the sediment. Nitrogen limitation and geographic factors further influenced the TOC/TN of aquatic matter. These processes accounted for approximately 40% of the total variance in sediment geochemistry, while around 50% of the variance could be attributed to local conditions, unaccounted geochemical processes, or different sediment timescales.

Summary: The term 'Blue Carbon' was coined about a decade ago to highlight the important carbon sequestration capacity of coastal vegetated ecosystems. Recent investigations have revealed high outwelling of dissolved inorganic and organic carbon, as well as particulate organic carbon from blue carbon habitats. This highlights the need to pay attention to the mobile carbon fraction in the blue carbon framework.

Summary: The development of biochemical techniques has made it easier to identify the animal species used in archaeological artifacts' raw materials, but these techniques are costly and involve destructive sampling. Research on a medieval chess piece revealed that its ivory came from an African elephant, potentially from an eastern or southern African country, contributing to understanding past trade networks.

Despite seasonal changes, shifts in vegetation can modulate belowground effects of future alpine climate change.

Summary: Climate change and droughts threaten the ecology and resilience of saline lakes globally. However, research on their ecological response to climatic events in the Global South is lacking. This study investigated the effect of a severe drought in South Africa on the trophic structure of fish communities in a saline shallow lake. The results showed that drought altered the availability of basal resources and affected the food web, but did not significantly alter the fish community itself.

Summary: We report the concentrations of dissolved CO2, CH4, and N2O in two large East African lakes, Edward and George. Lake George has lower levels of CO2, CH4, and N2O compared to Lake Edward, primarily due to higher phytoplankton biomass. Spatial variations in the concentrations of these gases are related to bottom depth and inputs from Lake George via the Kazinga Channel. Mixing events caused by storms can lead to increased emissions of CH4 and N2O in surface waters.

Summary: This study examines the debate surrounding the extent of forest coverage in the central highlands of Madagascar and analyzes the carbon and sediment dynamics of grassland and forest soils. The study finds that grassland soils have lower organic carbon content compared to forest soils, and that the grasslands have developed on soils previously dominated by C-3 plants. Additionally, the grasslands in valley positions contain more recent grass-derived organic carbon, likely due to higher productivity and erosion.
