Temporal changes in the Bothnian Sea food web reveal a deterioration linked to fishing pressure and recent eutrophication

ICES Journal of Marine Science, Journal Year: 2025, Volume and Issue: 82(3)

Abstract Changes in food web dynamics can have large and irreversible effects for many species, due to natural, climate-related, or anthropogenic factors. In the Bothnian Sea, changes key drivers, including climate change fisheries, raise concerns that are deteriorating. However, no method exists evaluating status region. We examine how Sea open sea has changed over time (1979–2021) using EU Marine Strategy Framework Directive criteria status. To analyse components potential we apply integrated multivariate analysis generalized additive models. Results indicate MSFD criterion ‘balance between trophic guilds’, mainly associated with herring fishing mortality, dissolved inorganic phosphorus, salinity. of species within guilds’ reflected increased cyanobacteria phytoplankton biomass, stickleback abundance planktivorous fish guild, declining Monoporeia affinis among benthic deposit feeders. The results corroborate a worsening measures such as lowering phosphorus loading mortality would prevent further depreciation. This study contributes development management objectives webs

Physiological responses of Atlantic cod to climate change indicate that coastal ecotypes may be better adapted to tolerate ocean stressors

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Healthy ecosystems and species have some degree of resilience to changing conditions, however as the frequency severity environmental changes increase, may be diminished or lost. In Sweden, one example a with reduced is Atlantic cod (Gadus morhua). This has been subjected overfishing, additional pressures such habitat degradation conditions there little no recovery, despite more than decade management actions. Given historical ecological, economical, cultural significance cod, it important understand how respond global climate change recover sustainably manage this in future. A multi-stressor experiment was conducted evaluate physiological responses juvenile exposed warming, ocean acidification, freshening, expected occur their nursery habitat. The response single drivers showed variable effects related fish biometrics increased levels oxidative stress dependent parameters. Importantly, two separate were seen within treatment for freshening groups. These within-treatment differences correlated genotype, offshore ecotype having heightened compared coastal ecotype, which better adapted tolerate future changes. results demonstrate that, while tolerance changes, ecotypes differently, cumulative multiple stressors lead deleterious species.
