Summary: This study investigated the variability in growth rates of Northern Pike in different lakes in the Northwest Territories of Canada, finding that lakes with greater catchment influence showed significantly slower growth rates for the fish. The study linked Northern Pike growth rates to trophic ecology and physicochemical data of the lakes and catchments, providing insights into potential impacts of future changes on fish growth and productivity in subarctic regions.

Summary: The study evaluates the ecomorphological relationship among 37 fish species in the Indian Sundarbans, focusing on identifying feeding guilds, understanding morphological relationships with diet, and assessing potential phylogenetic convergence. It highlights the importance of morphological differentiation in driving dietary variations and resource utilization patterns among coexisting species, while also suggesting the 8-Guild model as more representative of species feeding habits compared to the broader 3-Guild model.

Summary: This study investigated the levels of microplastics in the macroinvertebrate and fish community of the Dorset Stour river in SW England and tested the relationship between microplastic counts and ecological and morphological characteristics. The results showed that microplastic loadings were consistent within the communities but could not be predicted from any of their characteristics.

Summary: Research showed that the Pacific Marine Heatwave had impacts on rocky intertidal community structures across four regions in Alaska. Before the heatwave, there were significant differences in community structures among regions; however, during and after the heatwave, similarities in community structures increased, leading to greater homogenization of these communities.

Summary: This study assessed the vulnerability of five Pacific salmon species to invasive northern pike invasion using a modeling approach and Bayesian network, revealing pink salmon as the most vulnerable, followed by chum and coho salmon, with all five species being highly vulnerable in certain shared habitat. This framework can assist in prioritizing habitats and early monitoring of invading northern pike.

Summary: The study examined spatial patterns in diet, trophic niche width, and niche overlap of chum, pink, and sockeye salmon across the North Pacific. Different species showed variations in diet preference in different regions, with higher niche width and overlap in areas of high prey availability. Chum salmon demonstrated greater diet specialization compared to other species, especially in areas with abundant prey.

Summary: This study investigated the trophic position and isotopic niche of the blue swimming crab using carbon and nitrogen stable isotopes analysis. The results showed that the crab had a higher trophic position in the Mediterranean Sea compared to other areas. There was high inter-individual variability in the isotopic values, and no significant difference in the isotopic niche between male and female specimens was found. Furthermore, there was a significant correlation between specimen size and δ15N values, suggesting an ontogenetic dietary shift.

Summary: We analyzed the fatty acid composition of northern pike muscles from Gyda River in Siberia, Russia using gas-liquid chromatography. Out of the 43 identified fatty acids, 23 accounted for 99.3% of the total content. The fatty acid profile differed from other pike populations, possibly due to diet variations. Pike flesh had desirable nutritional qualities with a low n-6/n-3 ratio, low atherogenic and thrombogenic indices, and a high ratio of hypocholesterolemic to hypercholesterolemic fatty acids, making it a suitable replacement for traditional fish sources.

Summary: This study monitored the population of Syngnathus acus in Cies Archipelago, Spain and investigated changes in abundance, reproduction traits, trophic niche occupancy, and dietary regimes. The population consisted mostly of large adults, whose numbers decreased significantly after the breeding season. S. acus is a secondary consumer that prefers amphipods, but mature specimens were less selective than immature fish. The study highlights the unique features of the population in terms of size and occurrence of breeders.

Summary: Pelagic predators play a crucial role in sampling midtrophic organisms, especially in deep-sea habitats. This study investigated the diets and foraging behaviors of three poorly known deep-sea fish species by examining specimens from the stomachs of longnose lancetfish. We found high diet overlap but distinct differences in foraging strategies and prey sizes among the three species. Resource partitioning was observed, with each species specializing on different prey types.

Summary: The invasion of Round Goby in high diversity tributaries of the Laurentian Great Lakes has significant ecological impacts on native benthic riverine fishes, leading to changes in diet overlap and feeding strategy. The arrival of Round Goby resulted in an increase in ecologically significant diet overlaps among native benthic fishes, with some species shifting towards more specialized feeding strategies in response to potential competitive effects. These interactions may exacerbate the decline of native species in the long term, though the consequences of invasion-induced diet and feeding shifts remain poorly understood.

Summary: During primary succession, the ant community modifies its diet preferences and feeding habits, shifting towards plant-based diets in order to balance nutrition. Carbon and nitrogen isotope analyses of ants also support this finding.

Summary: The use of a global model for the Clupeiformes produces more accurate corrected δ13C values than species-specific models. At the order level, the linear model outperforms the mass-balance model.

Summary: Using otolith growth records of lake trout as a proxy for lake production, the study found a strong positive correlation between lake trout growth and temperature, suggesting that warmer springs and a longer ice-free season can promote lake trout growth. The results indicate that temperature can synchronize otolith growth across lakes, with or without the presence of sockeye salmon, and the presence of sockeye salmon did not improve model fit.

Summary: Invasive species introductions in high latitudes are increasing, and the effects of Elodea spp. on Subarctic and Arctic ecosystems, specifically its impact on fish life history, are still poorly understood. This study conducted a field experiment and found that Elodea spp. stands in a lake near Cordova, Alaska, led to reduced growth and lower trophic position for juvenile coho salmon compared to habitats dominated by native aquatic plants. The presence of Elodea spp. altered the energy flow to juvenile salmon by restructuring space and affecting prey resources, potentially leading to population-level impacts on salmon returns.
