Summary: Groundwater discharge plays a significant role in coastal aquatic ecosystems, but its patterns, importance, and effects on rocky shores communities are largely unknown. This study assessed the importance of groundwater discharge in intertidal ecosystems using benthic macroinvertebrate composition and abundance as indicators. The results showed that groundwater discharge significantly affected the abundance of biological communities across all shores, but did not impact biodiversity patterns. Certain algae, snails, and lichens could be used as bioindicators for shifts in groundwater discharge patterns.

Summary: The brachyuran crabs Carcinus maenas and Hemigrapsus sanguineus are successful invaders along coastal areas. They compete for food, with C. maenas better suited for animal food and H. sanguineus better suited for algae food. H. sanguineus can increase its utilization of algae food when animal food is scarce or competition with C. maenas is intense.

Summary: Environmental DNA metabarcoding is an effective method for assessing the diversity and biomarkers of aquatic invertebrate communities. Different wetland types exhibit significant differences in taxonomic composition and environmental impacts on invertebrate community structure. Understanding the composition and ecological characteristics of invertebrates is crucial for the conservation and management of wetland ecosystems.

Summary: Ecological stability depends on interactions between different levels of biological organization. Insurance effects occur when increasing species diversity leads to more stable community-level properties. This study investigates how species richness and population-level parameters influence community invariability.

Summary: A two-year experiment was conducted to investigate the impact of Pollicipes pollicipes harvest on intertidal community structure and ecological diversity. The study found that intensive exploitation resulted in a decrease in P. pollicipes and Mytilus spp. coverage, while Chthamalus spp. and Corallina spp. increased. The recovery of P. pollicipes aggregations was slow and variable, but their coverage increased under non-extracted conditions.

Summary: The study suggests that stream regulation and eutrophication influence the diversity of basal resources and biological trait changes in aquatic invertebrate assemblages. Isotope analysis and trait-based approaches provide complementary insights into ecosystem functioning, highlighting the potential effects of multiple stressors on trophic structures within aquatic invertebrate assemblages and the local dynamics of invertebrate communities in regulated river systems.

Summary: The relationship between resource quantity and quality and species richness at different spatial scales was evaluated in this study. It was found that at the local scale, species richness peaked at intermediate levels of resource quantity (chlorophyll a), but had a shallow negative relationship with resource quality (periphyton C:P and N:P). However, at the regional scale, species richness had a strong negative relationship with resource quantity and quality. This suggests that resource quantity has a greater impact on biodiversity than resource quality, consistent with patterns of eutrophication.

Summary: Changes in invertebrate body size-distributions following loss of habitat-forming species can impact ecological processes such as predation and competition. The study revealed predictable variation in size spectra of shallow epifaunal assemblages across reef microhabitats along an eastern Australian climatic gradient. While size spectra differed between major groups of microhabitats, there was little variability between tropical and temperate biomes. Ocean warming is unlikely to greatly alter epifaunal size spectra directly, but transformation of habitats due to warming may affect reef food web dynamics.

Summary: The Arctic Ocean is experiencing severe environmental changes, with microscopic data analysis showing shifts in the size structure of microbial communities and revealing a decline in total biovolume from summer to autumn, as well as a relative shift towards larger cell sizes in phytoplankton biovolume size-spectra in October.

Summary: This study describes a rocky intertidal food web in Golfo Nuevo, Argentina and evaluates the impact of green crab invasion on the network. By comparing pre-invasion and post-invasion scenarios, several network metrics were calculated. The green crab is positioned as a top predator, altering the structure and stability of the food web. The invasion decreases food web stability and has implications for assessing the effects of other global change factors.

Summary: This study investigates the responses of the gastrointestinal bacterial community in aquatic snails to dietary changes and changes in environmental conditions, and finds that the composition of the bacterial community is affected by salinity and food source. In addition, the presence of antibiotics disrupts the self-regulating mechanism of the host and results in decreased energy reserves.

Summary: A trophic model was constructed for the Poonthura Estuary, revealing that the ecosystem in this anthropogenically impacted estuary is impaired and differs in trophic functioning from estuaries with similar physical features. The study provides a pioneering step in understanding the ecosystem status and functioning of small, anthropogenically disturbed estuaries, and offers a theoretical and scientific basis for their management and restoration.

Summary: Climate change and human activities have significant impacts on lakes and their catchments, requiring a well-distributed and high frequency network to monitor environmental variables and share data efficiently. The PITAGORA project developed low-cost, easily implementable, and reliable instruments for measuring various environmental parameters, adaptable to different monitoring purposes.

Summary: The recovery time of ecological communities after disturbances differs, with multivariate composition taking longer to recover. This study used network analysis to find that changes in interaction strength are closely related to compositional changes, and rewiring of postdisturbance interaction strength is the main cause of observed compositional changes. Pesticide interactions are significant in the long term only when both interaction strength and food-web architecture are reshaped by disturbances.

Summary: Coastal marine ecosystems are crucial for Earth's biogeochemical and ecological functions, but are highly sensitive to the impacts of climate change and human activities. A study monitoring 12 sampling stations in 8 ecosystems in France over 2 decades found two abrupt changes in 2001 and 2005, indicating the influence of climate change on coastal ecosystems with trends towards increasing temperature and salinity, and decreasing chlorophyll a, nutrients, and particulate matter.

Summary: Algal polysaccharides, such as alginate, are an important organic matter source for marine heterotrophic bacteria, playing a key role in the oceanic carbon cycle. Research on the uptake of alginate by microbial communities revealed that specific bacteria can uptake alginate at the single-cell level, indicating niche specialization within heterotrophic communities and their quantitative role in coastal ecosystems.

Summary: The study found significant differences in diet and trophic levels of sea urchins at different latitudes, primarily influenced by local prey availability. Sea urchins adjust their foraging based on the small-scale distribution of food items, and changes in food source distribution may have important implications for food web dynamics and ecosystem functions.

Summary: Research using genome data and gas chromatography-mass spectrometry analyzed sterol profiles in different species of seaweed, revealing some conserved metabolic reactions but also variable pathways, potentially used for signaling molecule production. These new findings will facilitate further investigation into the biological roles of these algal pathways.
