Summary: Marine protected areas are important for conservation, but the increase in fish biomass within MPAs creates incentives for poaching. Fishing activities persist in most MPAs worldwide, raising concerns about monitoring and enforcement. A proposal for a Conservation Finance Area (CFA) utilizes leased fishing zones within MPAs to finance monitoring and enforcement, leading to greater conservation success.

Summary: Earthworms are invading soil communities worldwide, impacting ecosystem functions significantly as decomposers and ecosystem engineers. In northern regions of North America, invasive earthworms occupy empty niches in soil food webs and indirectly affect co-occurring invertebrate communities. The study reveals that earthworm invasion significantly affects the trophic niches of invertebrate species, leading to changes in basal resources and trophic levels.

Summary: Common sole in the eastern English Channel show strong interest in fisheries research, with a decline in recruitment and spawning stock biomass observed in recent years. Larval survival during the transition from endogenous to exogenous feeding is crucial, with good conditions observed near the coast and at the end of the spring season due to higher temperature and fluorescence values. The coastal migration pattern for sole larvae was consistent between 1995 and 2017, but with significantly lower larval abundances in the recent period.

Summary: The disappearance of sea ice in the Arctic region calls for urgent development of oil spill mitigation techniques suitable for ice-covered waters. The uncertainty surrounding oil spills in the Arctic is due to ice cover and sub-zero temperatures, which may affect natural attenuation efficiency. Research suggests that brine volume in ice at low temperatures may not be enough for biodegradation, whereas seawater is more suitable for this process.

Summary: Stable isotope mixing models are used to reconstruct animal diet, but current research neglects the dynamics of isotopic ratios and the impact of time lag on diet reconstruction. By using a dynamic mixing model, it is possible to more accurately estimate the consumer's diet and avoid misinterpretation in ecosystem functioning and food-web structure analysis.

Summary: The development and physiology of herring larvae were monitored in response to warming, acidification, and different food quality treatments. The experiment showed that warming and acidification resulted in a stress response at the molecular level and a decrease in herring larvae size-at-stage. The findings suggest that the predicted warming and acidification environment is stressful for herring larvae, potentially affecting their survival and recruitment.
