Summary: This study investigated the physiological responses of Euglena gracilis (E. gracilis) under semicontinuous N-starvation (N-) conditions in open ponds. The results showed that E. gracilis had higher growth rates and a higher paramylon content under N- conditions compared to N+ conditions. The study also revealed that E. gracilis exhibited similar cell numbers regardless of nitrogen concentrations, with relatively smaller cell size and unaffected photosynthetic apparatus under N- conditions. This adaptation ability of E. gracilis may have promising implications for the algal industry to achieve high productivity without relying on genetically modified organisms.

Summary: Major changes in North Atlantic zooplankton communities in recent decades have been linked to climate change, and the roles of environmental drivers are often complex. This study analyzed long-term monitoring data from the west coast of Scotland to investigate the decline in zooplankton abundance. The results showed that declines in abundance were partly explained by a negative trend in salinity, alongside the seasonal cycle and potential changes in offshore water masses.

Summary: The changing Arctic environment is influencing key zooplankton species such as Calanus finmarchicus, with areas near the ice-edge in the Fram Strait becoming more favorable for their habitat. This increase in suitable habitat is likely due to the long-term retreat of the ice-edge, allowing for earlier and longer phytoplankton blooms and higher temperatures that enhance copepod developmental rates. These changes can have significant implications for community structure and regional food-webs.

Summary: Demersal fisheries trawling is recognized as a significant cause of benthic disturbance, but sampling difficulties have limited our understanding of the phenomena. In this study, we conducted experiments to examine the influence of trawl gear on resuspended sediments and nutrients. The results show that sampling height and drag exerted by the gear affect the composition of particles and nutrients, with sediment particles being more influenced by gravity. The findings suggest that trawl gear design can be modified to reduce impacts on benthic ecosystems.

Summary: The traditional separation between primary producers and consumers in the marine food web is being replaced by the paradigm of mixoplankton, which are planktonic protists capable of both heterotrophy and autotrophy. This shift in understanding has implications for primary production, biomass transfer, and CO2 sequestration in the deep ocean. However, there is currently no tool to quantify the relative contributions of autotrophy and heterotrophy in planktonic protists, hindering our understanding of carbon cycling in marine ecosystems. This study explores the use of hydrogen isotopic signature of lipid biomarkers as a novel tool to investigate the prevalence of mixotrophy in marine microorganisms.

Summary: Sinking detritus particles play a crucial role in regulating global climate by transporting organic carbon into the deep ocean. We propose a new model that shows how the surface area of these particles increases during degradation, leading to faster remineralisation rates and reduced carbon sequestration. Our findings highlight the importance of further research to better understand the dynamics of particle surface area and microbial activity in order to improve global biogeochemical models.

Summary: The interface between freshwater and marine systems, estuaries, can act as a filter of the land-ocean carbon flux, removing terrestrially derived dissolved organic carbon (DOC). However, the fate of peat-derived DOC within estuaries remains poorly understood due to various factors. The study of DOC and inorganic nutrients in minimally disturbed Falkland Island estuaries revealed limited evidence of estuarine DOC removal, but observed hot zones of biogeochemical activity and in situ DOC production. This suggests that estuaries receiving high organic matter inputs can serve as analogues for natural biogeochemical functioning in temperate estuaries.

Summary: Zooplankton play an important role in ocean biogeochemistry, and their role in controlling atmospheric CO2 concentrations needs to be better understood. Pelagic mesozooplankton and micronekton communities influence the fate of organic matter through various ways, including consumption of primary producers and the active flux of carbon through diel vertical migration (DVM). The study provides insight into the biomass and metabolic budgets of mesopelagic animals, highlighting the need for a better understanding of lipid-storing animals and their influence on carbon budgeting in the pelagic.

Summary: The Vistula Lagoon, one of the two lagoons on the Polish coast, is economically and environmentally significant. This study aims to calculate the water balance of the lagoon before and after the construction of a canal through the Vistula Spit. The construction of the new connection may impact the lagoon's water balance and its biotic and abiotic environment. Data on precipitation, evaporation, inflow from the catchment, and inflow/outflow through the Strait of Baltiysk were collected for mathematical modeling. The study suggests that the construction of the new canal will not significantly alter the lagoon's water balance but may cause environmental problems.
