Summary: This study investigated energy sources and trophic interactions among vent fauna in deep-sea hydrothermal vents in the North Fiji Basin. The findings indicate that symbiont-bearing taxa have different carbon fixation pathways or nutrient preferences. Niche partitioning was observed among omnivores, with different resources or microhabitats being utilized. The crab was found to be the top predator in the ecosystem, consuming a variety of prey but with a lower preference for mussels. Overall, the vent fauna displayed non-overlapping diets and spatial niches, with each taxon having unique energy sources.

Summary: Stable isotope ratios of H, O, and C are informative of environmental exchanges, especially δ13C for latent heat flux under arid and low annual precipitation conditions. These stable isotope datasets collected by NEON contribute valuable information about bulk environmental fluxes useful for interpreting biogeochemical and ecohydrological processes.

Summary: The study found that mussels have higher trophic positions, requiring normalization of basal nitrogen isotope ratio. Spatial variations in nitrogen isotopic baselines in mussels reflect different nitrogen sources. Delta N-15 (base-bulk) and Delta N-15 (base-phe) are powerful tools for tracing nitrogen isotopic baselines.

Summary: Whiteman et al. (2021) utilized compound-specific stable isotope analysis (CS-SIA) with amino acid stable isotopes to quantify the extent of capital versus income breeding in emperor penguins. By reframing an important life-history trait as a spectrum rather than a dichotomy, they showcased the potential of CS-SIA as a tool for investigating resource allocation strategies in species. This study highlights the power of CS-SIA in unraveling life-history strategies of various species.

Summary: This study investigated the sources and biogeochemical processes of nitrate in Xi Bay, a coastal bay in Beibu Gulf, South China, using dual isotopes. The results showed that human activities, such as industrial and port activities, were the main drivers of nutrient enrichment in the bay. Microbial nitrification and external sources, including sewage, manure, soil N, and fertilizer, were identified as the dominant nitrate sources. Atmospheric deposition had a minor contribution to nitrate pollution in the bay.

Summary: This study evaluated the contribution of plankton to the production of tambaqui juveniles in ponds at different stocking densities. The results showed that plankton accounted for 22.75% of the fish biomass. Density had an impact on turbidity and Secchi, while final biomass and average density were the only zootechnical indexes that differed.

Summary: The study assessed spatial and temporal variation in the diet of the Eurasian otter in the Anzali Wetland through fecal and stable isotope analysis. Fish were found to be the main prey, with Prussian carp being the most important fish in the otters' diet. Some prey items showed seasonal variations, and the otter's trophic level was higher than other predators in the wetland.

Summary: Stable isotopes are increasingly used to understand the impacts of environmental changes on riverine ecological properties. The study found that the isotopic niches of fish in rivers are influenced by environmental gradients and human disturbance, with the spatial variation determined by external factors like epilithic periphyton and suspended particulate organic matter.

Summary: Stable carbon isotopes are a useful technique for partitioning CO2 exchange in ecosystems into GPP and respiratory components. By combining isotope technology and soil respiration, we developed a flux partitioning theory for mountain forest ecosystems and demonstrated its application using data from a temperate deciduous forest. This method provides a new approach for flux partitioning in forest ecosystems, particularly in mountain forests.

Summary: The presence of diamonds in alluvial deposits on the southwestern edge of the S & atilde;o Francisco Craton indicates the influence of subducted oceanic crust on the local mantle. The study of carbon and nitrogen isotope compositions of diamonds, as well as oxygen isotope compositions of their inclusion, reveals the contribution of different sources in the formation of diamonds, including altered oceanic crust and Earth's mantle. The isotopic signatures suggest that diamond-forming fluids may have originated from shallow oceanic crust and interacted with eclogitized substrates in deeper levels of oceanic crust. The research provides insight into diamond formation processes in subducted slabs and the subcontinental lithospheric mantle.

Summary: Mangroves are important for carbon sequestration, but future climate change and deforestation may have adverse impacts on their ability to store carbon. This study found that climate change will increase global carbon stocks in mangroves, exceeding losses from deforestation. However, under high-end scenarios, elevated temperatures and wider temperature ranges may increase the risk of carbon stock diminishment in some countries. Reducing mangrove deforestation rates would enhance the carbon benefit and make offsetting emissions through mangrove protection and restoration more attractive.

Summary: A new dataset combining geochemical and physical property data from 752 soil samples collected by citizen scientists has allowed for the first national estimates of the surficial soil organic carbon (OC) stock for Great British saltmarshes. The development of a new organic matter to organic carbon conversion method specifically for GB saltmarsh soil has enabled the inclusion of secondary data in the soil stock estimate.

Summary: Southeast Asia is considered to have high levels of marine plastic pollution, and it is important to understand its impacts and risks to marine ecosystems in order to develop mitigation measures. An international network of experts from various countries has set a research agenda for marine plastic pollution in the region, identifying key themes and research questions. Understanding the fate, degradation, and impacts of marine plastic pollution is crucial for tackling the issue effectively in Southeast Asia and providing insights for the rest of the world.

Summary: This study used meta-analysis to reveal the negative impacts of microplastics on seabed invertebrates, including feeding, survival, and energetics. The organisms exposed to microplastics showed negative responses compared to control groups, with embryos being the most strongly affected. Six out of seven biological processes were negatively impacted, and survival decreased significantly. The findings indicate that plastic pollution could have significant and enduring effects on the functioning of the ocean.

Summary: Coastal saltmarsh restoration can efficiently store carbon and uptake greenhouse gases. Globally, saltmarshes store approximately 1.41-2.44 Pg carbon. Restored saltmarshes have low greenhouse gas emissions and rapid carbon accumulation, with the potential to offset up to 0.51% of global energy-related CO2 emissions.

Summary: A study of seven mangrove forests in the Philippines showed that the abundance of roots near river mouths allows the forests to trap plastic litter. The research confirms that rivers are a major pathway for marine plastic pollution, and that mangrove roots play a crucial role in regulating the retention of litter. The results suggest that land-based waste management measures to prevent plastics from entering rivers will help reduce marine plastic pollution in Southeast Asia.
