Summary: The study reveals a 50% decline in surface krill abundance in the North Atlantic over the past 60 years, with no associated range shift. While warmer isotherms are shifting northwards, cooler isotherms have remained relatively static, leading to a narrowing of the core temperature range for krill distribution. This habitat squeeze may explain the decline in krill population and highlights the complexities of species response to warming temperatures.

Summary: The East Greenland Polar Front (EGPF) is an important front in the Nordic Seas, and its variations are closely linked to sea ice melting and North Atlantic water recirculation. Analysis using global ocean reanalysis data reveals that the intensity and area of EGPF show significant seasonal and interannual variations, with an increasing trend in recent years.

Summary: The study revealed a negative trend in Arctic sea-ice since 1979, particularly in the Barents Sea and Kara Sea, with significant sea-ice reduction in the Barents Sea. The research demonstrated that sea-ice cover in the BKS is influenced by SST, AT, and OLR.

Summary: Analysis of a large database of Holocene temperature time series challenges the concept of a globally synchronous Holocene Thermal Maximum. The discrepancies between climate reconstructions and model simulations highlight the need for reevaluation of climate models and proxy temperature records. The heterogeneous response to climate forcing indicates the lack of globally synchronous HTM.

Summary: The relative influence of fishing and climate-induced environmental change on fish stocks has been controversial. A new model called FishClim is introduced to estimate their interaction and influence, and it can help develop better strategies for sustainable fish stock management.

Summary: In order to provide better decision support, scientists have developed a unified dynamical-statistical prediction system to successfully forecast the biomass of cod stocks in the North and Barents Seas a decade in advance. Retrospective forecasts show differences in the prediction skill of the models, with North Sea cod stock possibly not recovering in the next decade and Northeast Arctic cod stock potentially declining but having a better chance of recovery.

Summary: Variability in the spatial and temporal distribution of mesozooplankton abundance in the N Alboran Sea was assessed from 2010 to 2020, and compared with historical data from 1992 to 2000. The study found significant differences in mesozooplankton abundance between the two time periods, as well as variations in composition throughout the seasons. Increasing temperature and decreasing predation pressure were suggested as the main drivers of mesozooplankton variability.

Summary: The study found a high stability of zooplankton community over time in the Gulf of Lions, with no significant long-term trends in density, size, and taxonomic composition. Variations in zooplankton size and density were not correlated to environmental variables, suggesting the importance of biotic interactions.

Summary: The distribution of Synechococcus in two Moroccan lagoons was examined using 16S rRNA amplicon oligotyping. It was found that the number of Synechococcus representatives was higher in the Mediterranean lagoon compared to the Atlantic lagoon. A total of 31 Synechococcus oligotypes were identified, which clustered into 10 clades with different distribution patterns. Clades IV and I had a higher relative abundance in the Mediterranean lagoon in 2014, which is unusual as they are commonly found in cold waters.

Summary: The state of Campeche in Mexico is home to a significant green turtle rookery. After the practice of harvesting the turtles ceased, the population began to rebound. A study of the relationship between the number of nesting females and the number of hatchlings produced over a 37-year period revealed a correlation that could be influenced by environmental factors, such as the Atlantic Multidecadal Oscillation cycle.

Summary: The study examined the changes in zooplankton communities in the southern Salish Sea during the 2015-2016 Pacific marine heatwave. It was found that there were variations in zooplankton biomass among different regions, with anomalously high biomass in the Puget Sound region. The changes in zooplankton communities were likely caused by factors such as increased water temperatures, nutrient-driven increases in primary production, and changes in species composition from the ocean. Further research is needed to understand the implications of these changes for the future food web.

Summary: This study investigates the factors affecting the year-to-year change in the intensity of synoptic-scale variability over the tropical western North Pacific during summer and fall. The study finds that sea surface temperature anomalies in the equatorial Pacific play a key role in modulating the background fields and intensity of synoptic-scale disturbances in the region. Furthermore, the research shows that SST anomalies in the tropical western Pacific have a notable impact on the intensity of synoptic-scale variability in the region. Opposite SST anomalies in different types of years lead to a weak relationship between the TWNP SSV and equatorial eastern Pacific SST.

Summary: The warming trends in the Indian Ocean and the North Atlantic Ocean are not only a result of increased greenhouse gases, but also influenced by atmospheric teleconnections. This study demonstrates that the interaction between these two ocean basins through atmospheric teleconnection reinforces their warming trends, creating a positive feedback mechanism. The Pacific Ocean also plays a role in modulating this warming chain. These findings highlight the importance of understanding ocean-basin interactions for more accurate future warming projections.

Summary: The number of small lakes on Earth, especially marine small saline lakes, plays an important role in the environment, society, and economy. However, there is a lack of studies in these environments. In this study, the authors investigated the variability of zooplankton and zoobenthos in a small hypersaline lake in Crimea. The results showed significant fluctuations in animal composition and abundance, but no direct long-term changes were observed.

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: Seafood is a vital source of protein globally, but balancing food security and ocean health is a challenge. The European Union adopts Ecosystem-based fisheries management to address this challenge, however, the impact of fisheries agreements with neighboring countries on EU ecosystems is often overlooked.

Summary: The study evaluated the epidemiology and genetic diversity of a non-native fungal pathogen in fish populations in France, revealing its potential widespread presence and limited detection in carriers. The Pseudorasbora parva populations showed homogeneous genetic and geographical structuring, suggesting the possibility of successive introduction events from native and invasive ranges in France.

Summary: In this article, the authors review the trade-offs in energy allocation between reproductive activities and maintenance, as well as the associations between reproductive activities, energy expenditure, and malignant cell dynamics. They argue that studying the interactions between host-oncogenic processes and life-history theory will be of significant importance for future research.

Summary: Understanding the spatio-temporal dynamics of glass eel recruitment is crucial for assessing eel population status and future stock. In this study, a Bayesian State-Space Model was used to investigate the temporal variations in glass eel recruitment in the Rhone delta (France). The results showed inter-annual variations in recruitment with no specific trend, as well as substantial spatial variations in the resulting recruitment. The findings highlight the importance of accounting for spatial heterogeneity in the dynamics of glass eel recruitment.

Summary: The study found that the total annual biomass-per-unit-effort is increasing in Lake Mikri Prespa, while the relative biomass-per-unit-effort of introduced species in the lake is also increasing over the years. Differences in trophic status between the lakes are reflected in species trend patterns.
