Summary: This study compares the body size structures, growth, metabolism, and size composition of meiofauna and macrofauna between a high-energy submarine canyon and the adjacent continental slope. The results show that larger individuals dominate on the slope while smaller ones dominate in the canyon, resulting in depressed community biomass, secondary production, and respiration in the canyon. Environmental factors such as bottom current velocity and sediment erosion duration significantly influence the body size composition of the canyon benthos.

Summary: Body size is an important trait related to abundance, home range, metabolic rates, and stressors. The relationship between body size and abundance in aquatic ecosystems, particularly for benthic macroinvertebrates, deviates from the expected value. This deviation may be influenced by various factors and the sampling methods used. Leaf-bags and Surber-net, two commonly used sampling methods, provide different data about body size and abundance of benthic macroinvertebrates.

Summary: This study used data from stream-fish surveys in northeastern Spain to examine the effects of species introductions on native fish communities. The results showed that translocated fishes had a greater impact on the individual size and abundance of native fishes, while exotic fishes had a positive effect on the abundance and richness of native fishes, with larger individuals being present. The study suggests that translocated fishes may become as problematic as exotic fishes, especially with increased angling and water transfers among catchments. The use of fish body size as a transferable trait in fish monitoring is also discussed.

Summary: Invasive species have significant impacts on environmental conditions, biodiversity, and ecosystem processes. The invasive aquatic plant Elodea canadensis has a pronounced effect on the biomass and metabolism of biofilms, increasing nitrogen availability and productivity while reducing nitrogen limitation.

Summary: Climate change affects benthic bioturbation in the southern North Sea, with temperature increase being the main factor. While overall bioturbation potential remains relatively stable, some species are projected to increase their bioturbation potential, leading to a change in relative contribution to bioturbation in the southern North Sea. This may have an impact on the biochemical cycling in sedimentary areas.

Summary: Invertebrate animals living at the seafloor have a significant impact on global ecosystems, but our understanding of their influence is limited due to difficulties in integrating information across sizes and sampling methodologies. This paper outlines practices that can support the establishment of Benthic Invertebrate Abundance and Distribution as an Essential Ocean Variable, including quantifying individual body size, utilizing automated information processing, and making data available through recognized access points. These practices enable broader-scale analysis and support research and sustainable development in marine ecosystems.

Summary: This study investigates the poor performance of the random forest algorithm with default parameters in species presence-background modeling, attributing it to class imbalance and class overlap. By proposing solutions and methods to manage imbalance and overlap, the algorithm's performance is improved.

Summary: Benthic-pelagic coupling refers to the combination of downward and upward flows of organic matter and nutrients between the pelagic and benthic domains mediated by trophic interactions. This study investigated the spatio-temporal variability of such flows in the Salento and Calabrian areas of the Northern Ionian Sea. The results highlight the important role of deep faunal communities in the BPC, which are influenced by temporal changes driven by the Adriatic-Ionian Bimodal Oscillating Systems (BiOS).

Summary: Damming has both short-term benefits and long-term negative impacts on the aquatic ecosystem. The Ba Lai dam in Vietnam's Mekong delta was studied to investigate its ecological impact on the estuary and its nematode communities. The dam was found to cause environmental differences and changes in the nematode communities.

Summary: The distribution of fruit pigeons on the island of New Guinea is influenced by geographical accessibility. The coexistence of species in a particular year and location is a nonrandom selection process. The sizes of these species are more widely spread and evenly spaced compared to random sets of species. Additionally, the local status of a highly mobile species decreases as other resident species become more closely related.

Summary: This study highlights the importance of understanding the patterns and potential processes underlying the island species-area relationship (ISAR) in freshwater lakes in different climatic regions. It provides a baseline for understanding how further changes to the ecosystem might influence biodiversity patterns.

Summary: This study investigated the disparity of responses shown by body-size spectra of periphytic ciliate communities when used as biomarkers to detect the toxicity of the broad-spectrum veterinary antibiotic nitrofurazone. The results demonstrated that body-size spectra and body-size distinctness offered clear evidence of nitrofurazone toxicity in periphytic ciliates. Therefore, body-size spectra can be used as a pivotal biomarker to determine the ecotoxicity of nitrofurazone in aquatic environments.

Summary: This study compares three different micronekton sampling gears and evaluates their impact on active carbon transport. The results show significant differences in estimated total active carbon transport between the gears, primarily driven by size-based sampling biases. These findings provide a foundation for future studies to adjust for sampling gear biases in active carbon transport research.
