Summary: When modeling an ecosystem, compromises must be made to preserve the essence of the system. In this study, Ecopath was used to model the plankton food web in the Strait of Georgia in different seasons. The changes in community composition and trophic behavior in the food web have implications for higher trophic levels. The inclusion of the microbial loop, although often excluded in coastal ecosystem models, is important in influencing trophic positions and transfer efficiencies.

Summary: Southern Ocean ecosystems play a crucial role in supporting globally important ecosystem services through their complex and regionally distinctive food webs. However, our current understanding of the structure, function, status, and trends of these food webs is limited, and the impact of climate change and human activities is expected to drive significant changes. Further development of assessment methods and management strategies is needed to conserve Southern Ocean food webs in the face of ongoing environmental challenges.

Summary: The study found that in some freshwater streams, trematode parasites play underappreciated roles in the ecosystem energetics, with their standing biomass exceeding that of aquatic insects and being only surpassed by host snails, sculpin, trout, and crayfish. The substantial parasite biomass stemmed from high snail density and infection prevalence, with infected hosts consisting largely of trematode tissue.

Summary: Complex systems often experience sudden regime shifts, known as critical transitions. Identifying warning signals for these transitions early enough to prevent them is challenging. In this study, we use landscape-flux theory to quantify the stability of ecological systems and provide early warning signals based on average flux, entropy production rate, non-equilibrium free energy, and time irreversibility. Our proposed method, demonstrated using a shallow lake model, can potentially predict critical transitions earlier than conventional methods, contributing to the resilience assessment of various ecological systems.

Summary: Levels of sociality in nature vary widely, and the dynamics of sociality under the selection pressure imposed by contagion remains elusive. In this study, a model for the evolution of sociality strategies in the presence of beneficial and costly contagion was considered. The results revealed a social dilemma, where the evolutionarily-stable sociality strategy was distinct from the collective optimum. The study sheds light on how contagion shapes the evolution of social interaction but highlights that evolution may not necessarily lead to social structures that are beneficial for all individuals.

Summary: Contemporary economic thinking neglects the fact that the human economy is interconnected with Nature and treats humans as mere consumers of natural resources. This paper suggests an alternative economic reasoning approach that focuses on the demand for Nature's services and its sustainable supply. It advocates for the measurement of inclusive wealth and its distribution by national statistical offices instead of relying solely on GDP. Policy instruments for managing global public goods, such as the open seas and tropical rainforests, are discussed based on the concept of inclusive wealth.

Summary: Infectious diseases can cause long-term damage to the host, leading to increased mortality even after recovery. The mortality due to 'long COVID' is an example of this potential, but the impact of such post-infection mortality (PIM) on epidemic dynamics is not known. Using an epidemiological model, researchers found that PIM can induce epidemic cycling, especially when there is weak PIM and no robust immunity. This overlooked phenomenon highlights the importance of characterizing heterogeneity in susceptibility for accurate epidemiological predictions.

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.

This mechanism provides cells with a favorable temperature environment, allowing for specific species and community growth rates to develop blooms under non-light limiting macronutrients and iron conditions. Our findings have important implications for increased productivity in a future warming climate.
