Summary: The study investigated large- and small-scale geographical variability in the Greater North Sea ecoregion using otolith shape analysis of European sprat. The results indicated that otolith shape follows the genetic population structure, supporting the latest revision of stock boundaries and identifying four main groups based on phenotypic variability. However, the low accuracy of crossvalidations using Linear Discriminant Analysis currently limits the operational use of otolith shape analysis for population identification.

Summary: Despite some institutional governance shortcomings, the majority of people in rural-connected areas of Chile get water through local rural drinking water committees, while most people in isolated areas obtain water from rivers without interacting with their neighbors. This highlights the importance of a multi-level contextual approach to rural water governance.

Summary: This study utilized the multivariate spatial scan statistic to identify geographic areas and times of sea lice infestation in farmed salmonids in Chile. The results revealed spatial clusters with different infestation levels and associated factors, highlighting the importance of Integrated Pest Management (IPM). Recommendations for an IPM plan were provided, considering factors such as stock density thresholds and chemical control efficacy to prevent resistance and minimize environmental residues.

Summary: Rainfall partitioning in secondary forests from southern Chile is important for the climate change context. The study found that the secondary rainforest intercepts 33% of total rainfall, with throughfall and stemflow being the main components that reach the forest floor. Canopy interception varies seasonally and is influenced by forest structure.

Summary: The study revealed a variety of mineral resources in the seabed offshore of Chile, with minerals such as quartz, feldspars, pyroxenes, and amphiboles being dominant. Framboidal pyrites associated with methane hydrates were found at depths greater than 900 meters, alongside reflective grains containing up to 58.3 wt% Cu, possibly derived from the continent or formed by in situ diagenetic precipitation.

Summary: This study discusses the climatic and vegetation conditions in southern South America during Late MIS 5 and MIS 3, highlighting high environmental variability and abrupt interruptions of interstadial conditions by glacial expansions. The Patagonian Ice Sheet reached its full glacial extent during Early to Middle MIS 3, suggesting millennial-scale climate changes characterized the pre-gLGM period at southern mid-latitudes.

Summary: This article analyzes the perceptions of rural social actors and experts on the peatlands of Chiloe Island, Chile. The study finds that there is a gradient of increasing loss in peatlands surface from South to North. Rural people show low direct use of peatland services and lack knowledge about peatlands. The study highlights the need to transfer knowledge to local communities and improve education about peatlands.

Summary: Using size-at-age data from field surveys, we examined how European plaice respond to spatial differences in environmental variables in the North Sea. We found that northern and southern migrating groups of males and females exhibited different growth patterns. However, these patterns were not supported by otolith-based estimates.

Summary: Estuaries and coastal areas with high nutrient inputs support highly productive fisheries and aquaculture operations, but also make them sensitive and vulnerable to human activities. Close monitoring of environmental conditions and productivity, especially at lower trophic levels, is necessary to ensure the sustainability of these ecosystems.

Summary: The growth and age characteristics of Diaphus brachycephalus in the South China Sea were studied through specimen collection and microscopic observation of otoliths. The relationship between body length and weight was determined, and it was found that there were no significant differences between sexes and survey stations. The growth rate decreased from juvenile to adult, and the hatching dates were speculated to be from March to November.

Summary: This study reveals that the seasonal and spatial changes of N. scintillans in the East China Sea and southern Yellow Sea are largely controlled by phytoplankton biomass, particularly the concentration of chlorophyll-a. The abundance of N. scintillans in the Changjiang Estuary significantly increased in 2011 due to accelerated eutrophication and warming, resulting in higher phytoplankton abundance.

Summary: The study analyzed the genetic structure of Baltic Sea pike using microsatellite markers, showing two distinct coastal clusters and a third cluster formed by lake populations. The research also found that the dispersal barrier is mainly caused by a sharp salinity leap, indicating a physiological rather than physical barrier.

Summary: This study investigated the selenium concentration in water, phytoplankton, and zooplankton in the Baltic Sea and analyzed the factors affecting selenium absorption and transfer. The results showed that the biomass of plankton played an important role in shaping selenium concentration, and seasonal and taxonomic changes also influenced selenium concentration.

Summary: In the present study, the otolith stable carbon and oxygen isotope ratios of Larimichthys polyactis were determined. The results showed significant differences in the isotopes ratios among different groups, indicating potential migratory routes. A schematic map of the migratory routes was depicted, providing important references for effective resource management.

Summary: Antarctic soil fungal communities are highly adapted to the extreme environment of the region, with abiotic conditions playing a key role in determining their structure. The communities show low resilience to environmental changes, which raises concerns in the face of global warming. Both abiotic parameters and species adaptation are crucial factors that influence the diversity and composition of these communities.
