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: Sea otters and wolves, two apex predators, have interacted for the first time after their ranges overlap, with sea otters becoming an abundant marine subsidy for wolves. The reintroduction and restoration of sea otters have caused a dietary switch in wolves, eliminating deer and linking nearshore and terrestrial food webs. This study highlights the unexpected nutrient pathway and cross-boundary subsidy cascades resulting from species restoration.

Summary: The study found that the biomass and diversity of aerial invertebrates from terrestrial origin landing on the streams increased with temperature, as did the biomass of ground-dwelling invertebrates falling into the streams. However, the biomass and diversity of terrestrial invertebrates drifting in the streams decreased with temperature.

Summary: Ingestion of contaminated prey is a major route for metal exposure in terrestrial insectivores. The study highlights the importance of considering both the proportion of different prey and their individual metal concentrations when estimating exposure risks for insectivores. Additionally, it emphasizes the need to account for metal exposure from emerging aquatic insects for terrestrial insectivores living close to lakes and streams.

Summary: The environmental fate of emerging contaminants at the aquatic terrestrial boundary is not well understood. This study focused on the bioaccumulation and bioamplification of pharmaceuticals and endocrine disrupting compounds in aquatic insects. The results showed variations in accumulation and amplification at different taxonomic levels. The study highlights the importance of taxonomy in understanding contaminant exchange between aquatic and terrestrial food webs. Predicting these processes with simple linear models was not successful.

Summary: Seabirds on islands play a crucial role in transferring marine-derived nutrients to the coast, enriching nearshore ecosystems. Invasive predators disrupt this land-sea linkage, and their eradication is important for restoring seabird islands. This study found that a combination of seabird and terrestrial abiotic variables influenced the composition of macroalgae communities surrounding islands. Season and depth were the main factors contributing to nitrogen enrichment.

Summary: Global declines in biodiversity can impact ecosystem function, and more research is needed to explore the biodiversity-ecosystem function connections across different ecological realms. Various linkages include cross-system subsidies, ecosystem engineering, and hydrology.

Summary: As global change alters ecosystems, the importance of subsidies from one habitat to another may change. This study manipulated black mangrove cover and found that increasing mangrove cover decreases the relative importance of marine subsidies into the intertidal at the plot level, but concentrates subsidies at the front edge of the mangrove stand. Storms may temporarily override mangrove attenuation of subsidies. The study emphasizes the importance of understanding the impact of changes in plant species composition on marine subsidies and exchanges among ecosystems.

Summary: This study found that the EPA content in aquatic insects did not differ with different degrees of habitat degradation, but crawling emergence significantly altered the contribution to total biomass export in spring under degraded conditions. The EPA content in ground-dwelling spiders was correlated with emergent stonefly biomass, and reduced crawling emergence might impact spider fitness. Functional traits, such as emergence mode and nutritional quality, should be considered when assessing the effects of stream degradation on terrestrial ecosystems.

Summary: Research has shown that aquatic organic matter (AOM) can be transferred from rivers to surrounding terrestrial ecosystems and decomposed by terrestrial organisms when extreme hydrological events occur. The decomposition rate depends on the type of organic matter, with AOM of animal origin decomposing more rapidly than that of vegetal origin. Microorganisms and vertebrates contribute most to the decomposition process.

Summary: Emergent insects play a crucial role in transferring aquatic nutrients to terrestrial food webs. The differences in fatty acid profiles between aquatic and terrestrial insects have not been sufficiently explored. This study examined the fatty acid profiles of aquatic and terrestrial insects over a growing season and found distinct differences between the two groups regardless of season. Aquatic insects had high proportions of long-chain polyunsaturated fatty acids (PUFA), while terrestrial insects had high proportions of linoleic acid. These findings highlight the importance of aquatic emergence as essential subsidies for riparian predators, especially during the breeding season.

Summary: Stream ecosystems rely on the exchange of energy between land and water to maintain a productive food web. Land use around streams can affect resource subsidies for stream predators. Forested buffers are often used to protect aquatic ecosystems, but their effects on resource subsidy source are unclear. Our study found that brown trout and spiders rely on terrestrial sources of prey, emphasizing the importance of maintaining functional riparian zones to support terrestrial subsidies into streams.

Summary: There is increasing awareness of the ecosystem engineering services provided by recovering populations of Eurasian beaver. By modifying aquatic environments, this species has a significant, positive influence on biodiversity. Our study in Poland compared the species richness and activity of terrestrial mammals at beaver ponds and randomly-selected reference sites. The results showed that beaver sites had higher species richness and activity, and the presence of beavers also rearranged the occurrence and activity of the terrestrial mammal assemblage.

Summary: Allochthonous resource fluxes mediated by organisms crossing ecosystem boundaries are crucial for resource-limited environments. Invasive species like black rats disrupt the natural pathways of nutrient subsidies. This study examines the role of seabirds in subsidizing terrestrial food webs and coral reefs in the Abrolhos Archipelago. The results show that seabird subsidies lead to overall enrichment of N-15 across the food web on islands. However, contrary to other studies, delta N-15 values were consistently lower within the seabird colonies, suggesting localized depletion in N-15 in small islands influenced by seabirds. Additionally, seabird presence has a higher effect on the base of the trophic web.

Summary: The Comparative Functional Response Approach (CFRA) is a practical method for forecasting the long-term impacts of potential invading consumers. This study examines the conceptual foundations of CFRA in relation to basic Lotka-Volterra consumer-resource theory. The findings suggest that while the CFRA holds true under certain conditions, predator impacts on prey abundance and stability are more influenced by variations in conversion efficiency and background mortality.

Summary: Predicting the combined effects of independent predators on shared prey requires considering nonlinear factors to avoid biases. Historical failures to account for biases introduced by nonlinear processes suggest a need for reevaluation of the general conclusions about the ubiquity of emergent MPEs.
