Summary: Monitoring and understanding the exploitation and stock status of target and bycatch species is crucial for fishery management and biodiversity conservation. This study developed an assessment framework using Japanese anchovy in the Bohai Sea as an example to address the challenge of lack of yield statistics. The framework allowed the estimation of anchovy stock status in the absence of yield data and can be applied to assess other fishery resources in similar situations.

Summary: The study of small pelagic fish in the Mediterranean Sea began in the Adriatic in the 1950's. Since 2009, internationally coordinated surveys under the MEDIAS action have been conducted to provide data for the management of small pelagics. The surveys cover EU Mediterranean waters and monitor the distribution using a common protocol.

Summary: Wetland plants play a significant role in wetland soil denitrification, but the effects of different plant communities are still unclear. This study found that wetland plants indirectly regulate soil denitrification by altering water content, nitrate concentration, and functional gene abundances. Co-planting Paspalum thunbergia and Phragmites karka can effectively improve nitrogen removal efficiency and mitigate eutrophication in adjacent aquatic ecosystems.

Summary: The study examines the contribution of species to plot biomass at different elevations in the tropical Andes region, finding that species abundance and frequency have varying impacts on plot biomass at different elevations. At lower elevations, species abundance is a better predictor of plot biomass, while less frequent species play a larger role in overall biomass contribution across elevations.

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: The study investigated the future shifts in temperate forest species composition and abundance due to climate change. It found that in the short term, biomass will increase and species composition will remain unchanged, but in the medium to long terms, changes in species composition will accelerate, with some species spreading and others declining, especially under extreme climate change scenarios.

Summary: Afforestation is crucial for controlling soil erosion and nutrient loss in the Loess Plateau in China. This study focuses on the impact of afforestation on soil nutrient changes, specifically looking at the effects of different vegetation types on understory vegetation and soil nutrients. The findings suggest that plant abundance, rather than species richness, is the key factor driving soil nutrient changes. Additionally, the abundance of shrubs and herbs differs in their contributions to soil nutrient variation depending on the vegetation type. It is also proposed that, in future assessments of vegetation impact on soil properties, phylogenetic relationships should be considered alongside species composition.

Summary: This study investigated the biology and abundance of turbot and thornback ray in Bulgarian Black Sea waters in 2020. Turbot is a valuable fish species in the Black Sea, while thornback ray is experiencing a decline in abundance in the Mediterranean region. The estimated stock biomass of turbot was 1467.6 tons with a relative abundance of 896,922 individuals, and for thornback ray, the figures were 1187.9 tons and 519,606 individuals. The study also analyzed the distribution of different length classes of these fish species and estimated the length-weight relationships.

Summary: Coastal wetlands are dynamic ecosystems that are vulnerable to climate-driven stressors. This study investigated how multiple stressors, such as elevated atmospheric CO2 concentrations and sediment deposition from hurricanes, would affect different wetland communities. The findings showed that encroachment of oligohaline marshes into freshwater forested wetlands can enhance belowground biomass accumulation and resilience to sea-level rise.

Summary: This study confirmed the presence of the dominant bivalve species, blood cockle (Anadara kagoshimensis), in the sandy and muddy areas off the coastal waters of the Black Sea. The population of blood cockles in the Southwestern Black Sea significantly increased in a single year, with Inebolu being the most widely distributed area. Blood cockles are ecologically important species in the Southern Black Sea habitats, and their study contributes to achieving Good Environmental Status (GES) and fisheries management in the region.

Summary: This study contrasted ecological stability based on statistical variability with the local stability of transient successional states. Results showed that while kelp exhibited less variability, barren grounds were more locally stable. The local stability criteria used in this study could help evaluate the stability of transient ecological states.

Summary: A mass-balanced and dynamical multispecies trophic model was constructed for a kelp forest ecosystem in the central-northern Peruvian coast, demonstrating the importance of the brown macroalgae Eisenia cokeri in the system. Analysis using EwE software indicated that this kelp forest is more developed but less resistant to disturbances compared to other kelp forests along the SE Pacific and Antarctic coast.

Summary: The macroscopic properties of a coastal benthic ecosystem in Mejillones Bay, northern Chile were compared using two multispecies trophic models constructed for the years 2006 and 2018. The increase in macroalgae, particularly Rhodophyta group, was the most significant change observed over the 12-year period. The analysis suggests that the ecosystem is moving towards eutrophic conditions based on the increase in Total System Throughput (TST) and decrease in Average Mutual Information.

Summary: The efficiency of two different substrates (natural vs. artificial) in promoting coral growth in three Pocillopora coral morphospecies was evaluated. The results indicate that substrate type does not affect Pocillopora growth, but seasonal changes have an impact. It is recommended to implement coral reef restoration programs during the warm season to enhance management actions in Isla Isabel National Park.

Summary: Human activities, including mining, tourism, port operations, fishing, and sewage discharge, have had a significant impact on the coastal area of Antofagasta Bay. This study assessed the benthic communities in different sectors between 2008 and 2011 and found that the communities were dominated by certain species. Sectors with medium to high levels of disturbances had higher species richness and diversity, while sectors with low disturbances had higher species dominance.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
