Summary: In agricultural systems, linear habitat features and resource shifting over the season can shape insect communities. Trait-based approaches are useful for understanding how environmental factors drive community structuring. In Mediterranean vineyard agroecosystems, linear habitat type and seasonality have different effects on Heteroptera communities, and trait composition is more sensitive to these factors than taxonomy.

Summary: Food webs play a crucial role in influencing ecosystem diversity and functioning. This study utilized extinct and extant mammal traits, geographic ranges, observed predator-prey interactions, and deep learning models to investigate the changes in terrestrial mammal food webs over the past 130,000 years globally. The results revealed significant declines in complexity of food webs due to loss of food web links after the arrival and expansion of human populations. The study estimates a 53% decline in food web links globally, primarily caused by extinctions but also by range losses for extant species. This highlights the potential for restoring food webs through recovery of extant species.

Summary: This study investigates how species invasions affect the structure, diversity, and stability of simple communities, and predicts the factors influencing invasion success and consequences. The results suggest that warm and productive habitats are more susceptible to successful invasions, with smaller competitors, intraguild predators, and relatively small top predators being the most successful invaders. Additionally, successful invasions can either destabilize or stabilize community dynamics, depending on the environmental conditions and the trophic position of the invader.

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: This study aimed to identify pathways of mercury accumulation in an alien species clams, Rangia cuneata, which serves as an unrecognized source of mercury pollution in the southern Baltic Sea. It was found that clams effectively detoxified xenobiotics in summer, resulting in faster growth and higher mercury accumulation in the shell. The concentration of mercury in clams was not determined by their sex, and the main form of mercury was mercury sulfide (HgS). Geographical changes in mercury concentration were related to the form of mercury in the sediment.

Summary: The study established empirical algorithms between CDOM absorption coefficient and reflectance band ratio using Sentinel-2 images, in situ data, and water chemical parameters. It showed that by considering trophic state and using specific band ratios, the geographical range of remote sensing-based CDOM models can be expanded. However, a decrease in accuracy was observed in eutrophic reservoirs, likely due to increased complexity of CDOM sources.

Summary: The study investigates the association between body size, trophic position, and the use of different energy sources in the Volta Grande rapids of the Xingu River. The results indicate that riparian vegetation plays a critical role in supporting the biomass of most aquatic organisms. Contrary to expectations, there was no gradual increase in the coupling of energy pathways with increasing body size and trophic position.

Summary: Many fish species use active and passive sound production for communication, but the field of bioacoustics and ichthyology has lacked a global inventory of known fish sound production. To address this, FishSounds.net was developed to compile and disseminate fish sound production information and recordings. The website currently catalogues research on active and passive sound production for 1185 fish species from 837 references, along with 239 exemplary audio recordings. Users can search the website based on taxonomy, geographical distribution, sound type, or reference.

Summary: Popular armored catfishes from South America have become invasive and can deplete basal resources, potentially impacting native fauna. A study in the Usumacinta River Basin, Guatemala, analyzed stable isotopes in fish tissues and basal resources to assess the trophic ecology of native fishes in the presence of Pterygoplichthys. The study found that the invasive catfish and environmental factors impact the trophic ecology of native fish.

Summary: The organic carbon stored in seagrass meadows is globally significant and could be relevant in strategies to mitigate increasing CO2 concentration in the atmosphere. Seagrass abundance is a good predictor of the soil organic carbon stocks, and the relative availability of nutrients N and P also influences carbon storage. Nutrient availability and eutrophication are likely to exert a strong influence on carbon storage in seagrass meadows.

Summary: Using histopathology, genomics, and transmission electron microscopy, the first symbiont profiles for Florida blue crabs (Callinectes sapidus) occupying freshwater to marine habitats were described. Twelve symbiont groups were identified, including ciliophorans, digenean, microsporidian, Haplosporidia, Hematodinium sp., Nematoda, filamentous bacteria, gregarine, Callinectes sapidus nudivirus, Octolasmis sp., Cambarincola sp., and putative microcell. Water temperature and salinity explained 48% of the variation in symbiont groups among Florida habitats, and salinity was positively correlated with C. sapidus symbiont diversity. Impaired crabs were more likely to host symbionts, and the microsporidian symbiont group had a particularly strong effect on C. sapidus reflex response. Considering full symbiont profiles and their associations with a spatially and temporally variable environment is important for assessing C. sapidus population health.

Summary: In this study, the effects of nutrient enrichment, salinity, and their interaction on the competitive interactions between a native macrophyte (wild celery) and a nonindigenous invasive macrophyte (hydrilla) were experimentally examined. The results showed that fertilizer enhanced wild celery's leaf area and aboveground biomass, but did not enhance hydrilla's competitiveness. Salinity negatively affected wild celery's leaf area and biomass, and also reduced hydrilla's belowground biomass production, but did not influence competition.

Summary: During lateral connections, aquatic organisms can assimilate material from oxbows and vice versa. This study analyzed hydrology, lateral connectivity, and stable isotope ratios to determine spatial food web subsidies between the active channel and oxbow lakes. The results showed that riparian C4 grasses were not a significant source of organic matter for fishes and mussels. Some organisms were observed to have assimilated ex situ source material, but further analysis using additional biomarkers and experimental approaches is needed to accurately track the movement of sources and organisms in spatially structured food webs.
