Summary: The Atlantification of the European Arctic is a complex phenomenon driven mainly by the changing properties of Atlantic water, leading to the alteration of local ecosystems towards a more temperate state and the appearance/range expansion of subarctic-boreal species at higher latitudes. This poses a threat to Arctic marine communities, with increasing biological complexity, (re)colonisation of boreal organisms, and the role of floating plastic debris in aiding the distribution of marine taxa as key factors.

Summary: The Pacific Arctic marine ecosystem has experienced significant changes in recent years due to global warming, sea ice melting and increased transportation of Pacific-origin waters into the Arctic region. These changes have impacted the distribution and abundance of larval fish populations in the northern Bering Sea and Chukchi Sea. The study found that the warming and loss of sea ice have led to shifts in fish assemblages, with boreal species expanding northward and Arctic species retreating poleward.

Summary: The Arctic Ocean is experiencing rapid changes, with the air temperature rising faster than global average. This has significant consequences for the ecosystems, especially for the polar zooplankton species. The study found that Arctic zooplankton species have a higher tolerance to ocean warming than expected, but they may be outcompeted by their Atlantic counterparts in areas of strong distribution overlap. Changes in zooplankton community composition and biodiversity will have major consequences for trophodynamics and energy flux in Arctic ecosystems.

Summary: This study assessed the temporal trends in functional diversity of deep-sea demersal fish communities in East Greenland, aiming to characterize ecological responses to rising sea temperatures. The findings revealed a decrease in functional diversity, associated with taxonomic and functional borealization, down to 1000 m, indicating an increase in mobile generalists and a decrease in bottom dwelling benthivores. The decline in functional diversity may have a negative impact on ecosystem resilience to environmental change. These responses are likely not limited to the study area and highlight the need for greater attention to ecosystem considerations in deep-sea climate change management strategies.

Summary: The seawater microbiome plays a crucial role in marine ecosystems. This study found significant differences in the composition of the microbiome between Spitsbergen and Greenland shelves, primarily influenced by salinity. The presence of cyanobacterium Prochlorococcus marinus in Arctic waters suggests the ongoing Atlantification and the potential impact of climate warming on the microbiome.

Summary: The study indicates that the increased liquid fresh water transport (FWT) between 2010 and 2015 in the East Greenland Current (EGC) has not continued, but instead decreased to pre-2009 levels. Additionally, there was a decrease in FWT in the Polar Water (PW) between 2015 and 2019, with occasional high FWT events in 2017. The reduced salt transport independent of reference salinity is related to a slowdown of the EGC.

Summary: In the Western Mediterranean Sea, there have been notable changes in the abundance, body condition, growth, reproduction, and distribution of forage fishes. These changes can be attributed to various factors such as increased fishing mortality, environmental changes, recovery of top predators, and increased competition. By using ecosystem-based modeling, researchers investigated the main drivers and changes in the pelagic ecosystem of the region. The results highlight the importance of considering these factors and adopting an ecosystem-based approach in managing the Mediterranean Sea.

Summary: The redistribution of marine biota in response to climate change and shifting seascapes is challenging to track due to discontinuities in biological observations, lack of data availability, and mismatch between data and real species distributions. The availability of data is identified as the most significant challenge in assessing species redistributions under global climate change. Combining multiple surveys is necessary to cover a significant portion of species ranges, and spatio-temporal modeling can help overcome differences in sampling schemes and inconsistency in sampling for tracking species redistributions.

Summary: This study analyzed the diet composition of western Baltic cod based on stomach samples collected using different fishing methods. The study found that cod in shallow areas primarily feed on benthic invertebrates instead of forage fish. The results also showed that the food intake of cod in deeper areas is influenced by catch depth, season, fish length, and other factors.

Summary: Species distribution models for marine organisms are increasingly utilized for spatial planning, conservation, and fisheries management. Various mathematical forms and physical/biological independent variables are used, with first-generation models mainly following linear or smoothing spline forms. Machine learning methods were used to evaluate different classes of variables, showing that physical and secondary production variables have the greatest contribution, while terrain variables have the least contribution. The presence and absence of species are defined by factors such as water depth, temperature, chlorophyll concentration, and specific zooplankton taxa, with strong seasonal variations.

Summary: There is a spatial and temporal coupling between ecological community composition and food web structure. Changes in community composition affect the structure of food webs, with a strong spatial coupling observed in the North Sea. However, the temporal covariation between community composition and food web structure depends on the spatial scale, with a temporal mismatch at the regional scale but a strong coupling at the local scale.

Summary: This study explores the importance of gender norms in agricultural innovation and presents an integrative research approach that incorporates local conditions to inform the design and targeting of gender-inclusive interventions. The concept of gender climate is used to describe the socially constituted rules that dictate men's and women's behavior. The findings suggest that favorable economic or infrastructure conditions do not necessarily correlate with favorable gender normative conditions.

Summary: This study investigates the key reproductive traits of three different species of fish and finds that all of them are batch-spawners, which may be an advantage in coping with the variability in food supply and other risks for offspring survival. The study also discovers that the electric lantern fish has two year-classes and only experiences one spawning season per lifetime.
