Summary: In trait-based ecology, it is common to use measures to quantify phenotypic variation between populations. However, these measures overlook the within-population trait variability and some of them cannot be partitioned between populations. This study proposes a new measure called the phenotypic dissimilarity (PhD) index to address these issues and provide a tool for quantifying phenotypic variation within and between species.

Summary: This study explores the use of otolith microchemical composition as a tool to differentiate A. carbo specimens caught in different areas, and studies the potential birth areas and spatial migration patterns throughout the species' life cycle. The results show that otolith microchemical composition can discriminate the locations where specimens were caught, supporting the separation between the northern and southern distribution areas of A. carbo. The study also suggests the existence of two natal sources and confirms the migratory behavior of A. carbo.

Summary: Due to a lack of biological information on population structure and spatial dynamics of capelin that spawn in Greenland, there is currently no sustainable fisheries management advice available. This study analyzed chemical tracers in otoliths from 549 spawning capelin to provide a chemical baseline for investigations of migration and population structure in Greenlandic waters. The results demonstrate the applicability of otolith chemistry as a tracer of physicochemical variation in an arctic marine environment undergoing rapid climatic changes.

Summary: This study investigated the spawning grounds and habitat use patterns of Acanthopagrus latus in the waters surrounding the Wanshan Islands in China. The findings revealed that the spawning area of A. latus originated from low to medium-salinity waters with mangroves and oyster farm habitats in the Pearl River Estuary. A. latus showed widespread migration between estuarine and marine habitats throughout its life cycle. These results have important implications for future fisheries management.

Summary: Understanding the spatial and temporal scales of key population processes is crucial for effective recovery actions in fisheries management. The study on three potamodromous species in the Darling River showed that golden perch were mainly locally spawned, while Murray cod were mainly lifelong residents and silver perch mostly immigrated from the Murray River. Recovery actions in the Darling River should consider the relevant spatial and temporal scales of life history processes.

Summary: Plasticity can have direct effects on the interactions between species, by expanding or shifting interaction niches, and ultimately modifying the structure and functionality of ecological networks. This causal pathway may explain how interaction niches evolve quickly in response to rapid environmental changes and is important for understanding the impact of global change on ecological interactions.

Summary: Dams can facilitate the colonization and spread of aquatic invasive species, as seen in the case of European perch in the Solina Dam on the San River system in Poland. Extensive sampling and otolith microchemistry analysis revealed that while perch were widely distributed upstream of the dam, they primarily shared the same spawning and larval rearing habitat, likely the Solina Reservoir. This study highlights the importance of reservoirs in providing critical habitat elements for colonizing river systems.

Summary: Eels exhibit a high level of phenotypic plasticity in response to biogeographical drivers and local conditions. This study provides a biogeographical snapshot of eel life-history traits, showing geographical and salinity variations. Eels grow faster and migrate earlier in southern Europe, suggesting local growth conditions play a larger role in silvering process than fish age. Eels with a brackish life-history grow faster, reach larger size-at-age, and have better condition, indicating the importance of brackish areas for eel production. However, a large proportion of the variation in life-history traits remains unexplained, implying other drivers at the catchment scale.
