Summary: This study investigated the diet of benthic suspension feeders, such as corals, using fatty acid trophic markers. The research found that deep-water corals primarily feed on zooplankton, while shallow-water corals primarily feed on diatoms and flagellates. Furthermore, the study highlighted the limitations of using FATMs as diet tracers in limiting environmental conditions.

Summary: Compound-specific stable nitrogen isotope (delta 15N) analysis is a powerful tool for studying trophic dynamics and nitrogen biogeochemistry. This study presents a refined analytical technique and compares different sample pretreatment methods, providing high-resolution data for reconstructing changes in the origin and fate of nitrogen in aquatic food webs.

Summary: The northern Humboldt Current upwelling system is one of the most productive marine ecosystems, with fisheries landings five to eight times higher than other coastal upwelling systems. A study was conducted to understand the pelagic food-web structure and trophic interactions in this system. The study found regional shifts in the food web and differences in δN-15 ratios between surface waters and the oxygen minimum zone. Additionally, the role of benthic-pelagic coupling and the importance of certain key species in the zooplankton community were identified.

Summary: This study characterized the nutritional value of SPOM in the Guadalquivir River Estuary using a fatty acid-based index, showing seasonal and salinity-related variations in SPOM nutritional quality. A mixing model using bacterial fatty acids provided accurate estimates of the contribution of autotrophs and heterotrophs to microbial biomass.

Summary: The invasive freshwater bivalve Limnoperna fortunei shows strong physiological adaptability to environmental changes, particularly after feeding on cyanobacteria at high temperatures where it exhibits increased fatty acid biosynthesis, such as EPA and ARA, providing an important source of PUFAs for higher trophic levels. This transfer of responses from cyanobacteria to higher trophic levels can significantly impact the overall functioning of freshwater ecosystems.

Summary: This study assesses the plastic and genetic potential of response to elevated temperatures in the tropical bivalve Pinctada margaritifera. The results show that the bivalves have the capacity to adjust to long-term elevated temperatures and suggest the need for longer term studies to evaluate population resilience in the face of climate change.

Summary: Abyssal seafloor ecosystems, which cover more than 50% of the Earth's surface, rely on the flux of organic matter from the ocean's surface layer. This results in significant variations in food availability and limitations for bottom-dwelling organisms.

Summary: Intestinal flora plays a crucial role in maintaining the balance of the human body's ecosystem. By interacting with polysaccharides, the gut microbiota can be regulated to improve health and prevent disease. Polysaccharides, as prebiotics, have the potential to enhance human health by modulating the composition of gut microbiota.

Summary: The present study aims to combine oceanologic measurements and biochemical analysis to reveal the trophic conditions and environment state of Antarctic krill in real time. By analyzing the fatty acid composition of Antarctic krill samples collected from different water areas, significant differences were found, indicating regional variations in abundance and foraging ability. Additionally, the study discussed the impact of abiotic factors using CTD measurements. The results suggest that Antarctic krill undergo compensatory modifications in the composition of fatty acid components to adapt to different habitat conditions.

Summary: This study cloned fatty acid desaturases and elongases genes from Ruditapes philippinarum and analyzed their tissue distributions. The expressions of these genes were significantly higher in the digestive glands and intestine. Feeding the bivalves with microalgae of varying fatty acid compositions showed that the bivalves can modulate gene expressions to adapt to different dietary compositions and have the capacity for LC-PUFA biosynthesis.

Summary: Consumer liking of different types of lamb meat varies based on tenderness, juiciness, flavor liking, and overall liking. The study identified two consumer clusters with distinct preferences, where one group favored lamb with lower total lipid content, specific fatty acids, and volatile compounds, while the other group showed less influence from fatty acids and volatiles except for certain specific acids. This suggests that fatty acid profile and volatile compounds play a significant role in driving consumer liking for lamb for some consumers more than others.

Summary: Earthworms are invading soil communities worldwide, impacting ecosystem functions significantly as decomposers and ecosystem engineers. In northern regions of North America, invasive earthworms occupy empty niches in soil food webs and indirectly affect co-occurring invertebrate communities. The study reveals that earthworm invasion significantly affects the trophic niches of invertebrate species, leading to changes in basal resources and trophic levels.

Summary: Time series data from a moored array of sensors are used to describe the long-term mean circulation and seasonal variations on the West Florida Continental Shelf. The observations reveal a coherent shelf-wide circulation pattern with alongshore and down-coast flow, and a coastal jet separating an upwelling region from a downwelling region influenced by the deeper ocean.
