Summary: Artificial reefs can support trophic structure and pathways similar to those of natural reefs, although there may be spatial differences in pathway magnitudes. The study shows that the development of artificial reef systems over the years enables them to be comparable to natural reef systems. Future research should focus on comparing specific trophic compartments and combining trophic ecology with community structure to better understand the development of artificial reef systems.

Summary: The study examined the effects of rock pool physical properties and seasonal changes on food web structure in a warm temperate coast of South Africa. The results showed that factors such as water depth, pool size, phosphate concentrations, salinity, and temperature all influenced overall food web dynamics, with effects moderated by seasonality.

Summary: This study investigated the correlation between behavior type and diet in a protected population of Atlantic cod. By using acoustic telemetry and stable isotope compositions, the researchers determined the behavior and diet of the cod. The study further explored whether there were survival costs associated with behavior and diet.

Summary: In this study, the predator-prey interactions and trophic structure of the pelagic fish community in the Bay of Biscay were investigated using stomach content analysis and stable isotope analysis. The results showed that trophic guilds were more influenced by intra-specific affinities rather than seasonal variability. Vertically migrating meso- and macrozooplankton played an important role as a food source for the pelagic fish community, and there was high trophic overlap among most species. The trophic structure did not differ between spring and late summer, but the trophic positions were consistently lower in spring.

Summary: During the MERITE-HIPPOCAMPE campaign in the Mediterranean Sea, plankton samples were collected from 10 stations from the French coast to the Gulf of Gabe`s. The study found that the sources of carbon and nutrients in plankton vary depending on the coast and offshore area, and the size and nutritional content of plankton increase with size. The results also highlight spatial variations in the trophic structure of plankton size-fractions, which can contribute to the assessment of plankton as a biological pump of contaminants.

Summary: In order to evaluate the impact of rainfall on the basal resources supporting food webs, we compared stable isotope ratios (813C and 815N) of fish consumers and organic matter sources between up- and down-sites in an estuary across different seasons and years. Our study found seasonal differences in the isotopic values of basal resources and fish consumers in both years. Changes in rainfall period resulted in significant differences in the isotopic values of fish consumers at the up-site, indicating a shift in food availability. However, the isotopic values of fishes remained consistent at the down-site, suggesting a negligible impact of rainfall on fish resources.

Summary: The food and feeding relationships in the Ulhas River Estuary (URE) were analyzed using stable carbon and nitrogen isotopic signatures. The results showed that there were both a phytoplankton-based pelagic food chain and a detritus-based benthic food chain in URE. The ecosystem in URE exhibited a broader food web structure and higher trophic diversity, indicating the influence of anthropogenic activities on nitrogen pollution and trophic disturbance.

Summary: The trophic structure of the zooplankton community in Daya Bay reflects the health of the ecosystem and the impact of human activities. This study investigated the stable isotope values (813C and 815N) and trophic positions of dominant zooplankton groups in Daya Bay during winter. The results showed that the distribution of isotopic values was influenced by terrestrial organic matter input and nutrient loading. Eutrophication increased trophic overlap between zooplankton groups, and large Sagitta was identified as the top predator in the community.

Summary: Radiogenic strontium isotopes (Sr-87/Sr-86) are a useful tool for investigating migration and landscape use. The study shows that the Sr-88/Sr-86 ratio may reveal unknown dietary and physiological information. Furthermore, the delta Sr-88 values in tooth enamel can differentiate between plants and herbivores, but the distinction between herbivores and carnivores requires further research.

Summary: This study investigated the spatial and seasonal distributions of stable carbon and nitrogen isotopes in dominant zooplankton groups in Jiaozhou Bay. The results showed that the distributions of these isotopes were influenced by terrigenous organic matter input and phytoplankton biomass, with variations observed in different seasons. The study also found a correlation between small zooplankton stable isotope values and particulate organic matter. The influence of anthropogenic nutrient input on isotopic baseline and trophic levels of zooplankton groups was discussed.

Summary: Stable isotopes of Antarctic ice cores are widely used in reconstructing past climates. This study analyzes the spatio-temporal variations of snow accumulation and stable isotopic composition in two regions of East Antarctica and evaluates the impact of diffusion on isotope records. The study finds that the variations in delta O-18 and delta D are primarily influenced by snow accumulation and temperature. Furthermore, the study reveals that diffusion does not significantly impact the dating and paleoclimatic interpretation of isotope records in high accumulation areas of coastal Antarctica.

Summary: Marine neuston, a group of zooplankton that live near the ocean surface, is one of the least studied zooplankton groups. This study characterized the neustonic communities across different oceanic provinces and found that the differences in stable isotopes are related to environmental characteristics. The trophic structure of neuston communities is generally consistent across different regions, but the size and overlap of trophic niches may vary depending on food availability.

Summary: Protein domains are crucial units for protein classification, function understanding, and design, with various prediction methods and databases available in the past two decades. These methods are categorized into sequence-based and structure-based approaches, each with its own advantages and limitations. Popular online protein domain databases are overviewed, with discussions on potential improvements of prediction methods.

Summary: The Himalayan mountain range produces large rainfall gradients and the Indian Summer Monsoon contributes to most of the precipitation in the central Himalayas. However, the partitioning of moisture into different storage systems and their contribution to river discharge remains unclear. In this study, field data and stable isotope composition of river and rain water were used to understand hydrological variability. The study found that pre-ISM rainfall is distinct from monsoon rain and groundwater. The research highlights the importance of pre-ISM precipitation and groundwater as sources of river discharge in the central Himalayas.
