Summary: This study analyzed high-frequency data on phytoplankton and environmental factors in Jiaozhou Bay and found that the abundance of phytoplankton exhibited a two-peak pattern of annual variation in recent years, with a decrease in species diversity. The increase in water temperature and intensification of eutrophication led to a more single dominant species, resulting in decreased community diversity and stability. Temperature was identified as the main driving factor influencing phytoplankton community structure, particularly during peak periods. Nitrogen and phosphorus were also important factors influencing species composition and competitive advantage.

Summary: This study investigated the spatial and temporal variations in phytoplankton community compositions in the southern coastal waters of Korea (SCWK) using high-performance liquid chromatography (HPLC) analysis of photosynthetic pigments. The results showed that diatoms were the dominant groups in the SCWK, especially in cold seasons. Cyanobacteria became dominant in summer due to water stratification caused by temperature and salinity discrepancies. Macronutrients, such as dissolved inorganic nitrogen, dissolved inorganic phosphate, and dissolved silica, were found to have a strong positive correlation with diatoms. Further research on the responses of small-sized prokaryotic phytoplankton, especially cyanobacteria, to environmental variations would help improve our understanding of the SCWK ecosystem.

Summary: This study examined the impact of environmental change on the phytoplankton communities in the coastal waters of the Eastern English Channel. The results showed that the species richness of phytoplankton was influenced by various factors, including wind-driven processes, nutrient supply, temporal niche differentiation, and competition-defense and growth-defense trade-offs. The study also found that the reduction of unbalanced nutrients facilitated the growth of Phaeocystis blooms, while climate warming and nitrate reduction may pose a threat to diatom communities in the future.

Summary: Subtropical systems experience occasional severe floods that lead to significant changes in phytoplankton community structure. A study in an Australian subtropical bay found that a 1:100 year summer flood resulted in rapid shifts from micro-phytoplankton dominance to nano- and pico-plankton dominance. This shift was attributed to increased nutrient availability stimulating the growth of smaller phytoplankton species.

Summary: This study demonstrates the relative significance of ecological mechanisms in shaping microbial communities in the Pacific Ocean, specifically in terms of selection, dispersal, and drift. Temperature plays an important role in determining the importance of homogeneous selection and dispersal limitation in community assembly. Co-occurrence-based community metrics are found to be better indicators of biogeographic patterns compared to compositional or phylogenetic distance measures. These findings contribute to our understanding of microbial community assembly processes and their role in global biogeochemical processes.

Summary: Coastal climate impact studies are increasingly using multi-source and multi-dimensional atmospheric and environmental datasets to investigate the relationship between climate signals and ecological response. This research applies dimensionality reduction techniques to study the impacts of atmospheric processes on coastal chlorophyll-a concentrations in the Dutch Wadden Sea. The techniques are able to incorporate spatial correlation, temporal correlation, and functional variability, and identify important atmospheric variables affecting chlorophyll-a concentration. The results show potential for dimensionality reduction in atmospheric variables, chlorophyll-a time series, and climate projection scenarios. Solar radiation and air temperature are found to be the most important atmospheric variables, with regional differences in their importance.

Summary: Pelagic primary production is the main input of organic energy for benthic production below the photic zone. Changes in phytoplankton species composition and bloom dynamics, as a consequence of climate change and eutrophication, are reducing high quality diatoms reaching the benthic fauna and promoting cyanobacteria. The investigated macrofaunal species display a selective feeding behavior with preference for spring-bloom associated diatoms, indicating that changes in phytoplankton bloom composition are likely affecting benthic species composition and production.

Summary: This study investigates the impact of different seasonal, quality, and quantity of plankton communities on benthic metabolism. The results show that the quality of organic matter is crucial in determining the fate of organic nitrogen once it settles to the sediment surface, with N-rich plankton deposition favoring nutrient cycling over N-loss via denitrification. This highlights the complex interplay between quantity and quality of organic matter in regulating nitrogen cycling.

Summary: Using DNA metabarcoding, this study calculated prey selectivity indices and energy fluxes in a pelagic food web. It found that food web dynamics are influenced by prey selectivity and temporal match-mismatch in growth cycles, and that cyanobacteria are the main source of primary production in the investigated coastal pelagic food web. The study provides a method for quantifying energy fluxes in marine food webs using DNA metabarcoding and suggests its potential extension to other ecosystems.

Summary: Macrobenthic organisms in temperate latitudes below the photic zone rely on organic matter sedimentation as their energy source. A study in the Baltic Sea found low seasonal variability in fatty acid content of benthic macroinvertebrates despite high seasonal variation in phytoplankton species composition. Each benthic species had distinct levels of major fatty acid groups, suggesting adaptation to degraded sedimenting material. Species composition of benthic macrofauna affected nutrient availability to higher trophic levels more than seasonal changing conditions.

Summary: The hound needlefish Tylosurus crocodilus is popular in local markets of Tanzania, but overfishing due to the growing coastal population threatens its sustainability. This study used the COI gene to assess the genetic population structure and connectivity patterns of T. crocodilus in Tanzanian coastal waters. The results showed low genetic diversity and no significant genetic structure among populations, indicating high genetic connectivity. However, recent demographic expansion was detected, suggesting the need for management actions to prevent genetic diversity loss and the effect of genetic drift on populations.
