Summary: The expression of life-history traits in fish is influenced by both current and past environmental conditions. This study investigates the effects of carry-over from larval traits and environmental conditions on the life-history traits of European seabass using otolith microstructure analysis. The results show that larval traits have a minor impact compared to the nursery environment on post-settlement traits.

Summary: This study investigated the patterns of fish co-occurrence in Amazonian streams and identified the environmental and spatial processes that determine these patterns. The results showed that most co-occurrence patterns were random and composed mainly of rare species, while a subset of species formed non-random aggregated or segregated pairs. The formation of these pairs was determined by biotic interactions, environmental filters' action, and/or limiting species dispersal.

Summary: Plankton-fish interactions are a crucial topic in marine ecology. Besides direct predation, there are non-lethal implications in the relationship, such as reduced reproduction rate of zooplankton due to fear of predation. This study analyzes the role of fish-induced fear in zooplankton and its carry-over effects using a population model. The model considers functional responses to capture the interplay between phytoplankton, zooplankton, and fish. Theoretical analyses and numerical simulations reveal the impact of non-lethal parameters and fear on population densities. The study has significant implications for understanding nonlinear models in plankton-fish ecology.

Summary: The study found that the abundance of microplastics in shrimp meal was significantly higher than in fish meal, with most of the microplastics in shrimp meal being 1-5 mm. Eight colors of microplastics were observed, including black, red, and orange microplastics. Fiber-type microplastics were mainly composed of olefins and polyester, while film- and fragment-type microplastics were mainly paraffin and polyethylene.

Summary: The global demand for raw materials used in animal feed has been steadily increasing in recent years, with a frequent presence of mycotoxins in these materials raising concerns for human health. Research on the occurrence of mycotoxins in feed, their metabolism and transfer into animal source foodstuffs in the past decade indicates a significant issue that warrants attention.

Summary: This study investigates the long-term physiological effects of early hypoxia exposure in the economically significant species Pacific abalone, revealing that juvenile abalones exposed to hypoxia at early development stages exhibit higher hypoxia tolerance but slower weight growth. These phenotypic effects are driven by strong selection of genes involved in signal transduction, autophagy, apoptosis, and hormone regulation, as well as the regulation of long non-coding RNA.

Summary: The justification for promoting tourism development lies in its ability to generate spillover effects on traditional economic activities. This study examines the relationship between tourism development and the local fisheries sector, finding that fisheries benefit from tourism growth in terms of increased value rather than increased volume of catches.

Summary: In this study, the authors investigated the behavioural changes in the acellular slime mould Physarum polycephalum with age. They found that migration speed decreased with age, but decision making and learning abilities did not deteriorate. Older slime moulds were able to temporarily recover their behavioural performances through a dormant stage or fusion with young slime moulds. Additionally, both old and young slime moulds were attracted preferentially towards cues released by young slime moulds. This study expands our knowledge on the behavioural plasticity of single-celled organisms and highlights slime moulds as a promising model for investigating the effects of ageing on behaviour at the cellular level.

Summary: This study assessed the influence of pre-breeding diet on seahorse reproduction for the first time, showing that feeding a mixed diet (Artemia and mysidaceans) throughout the pre-breeding period can enhance breeding performance and newborn size and quality. Isotopic analysis revealed a stable state in newborn batches after the second month of the breeding period, highlighting the importance of pre-breeding diet on seahorse reproduction.

Summary: This study explored marine biodiversity and potential species associations in eight Arctic marine areas from 2000 to 2019. The research found that species richness in the Arctic has been increasing in the past 20 years, indicating potential emerging areas of species accumulation due to climate-driven species redistribution. Regional species associations were dominated by positive co-occurrences, especially in the Pacific and Atlantic Arctic areas. Comparative analysis of sea ice concentrations revealed contrasting impacts on species richness, community composition, and co-occurrence, highlighting the vulnerability of Arctic marine areas to climate change.

Summary: This study found that environmental variables in the fall, especially the number of freeze-thaw events, influence late-winter fecundity of Canada jays, which in turn drives population growth. Warmer and more variable fall conditions may accelerate the degradation of perishable food, potentially impacting long-term population dynamics.

Summary: Predation-driven Allee effects are important in the dynamics of small prey populations, especially when a generalist predator targets specific prey. Fear of predation and its carry-over effects play a significant role in the stability of coexistence equilibrium, even for models with type I functional response. The study shows how non-lethal effects can change the dynamics of a prey-predator model and provides insights for understanding small population dynamics.

Summary: This study investigated the direct and indirect effects of fire on the network of relationships among soil prokaryotes in a Chilean sclerophyllous ecosystem. The results showed that the network parameters of bacterial communities in burnt soils differed most from those in unburnt soils, while the networks in burnt and unburnt rhizosphere soils exhibited similar characteristics. The bacterial community structure in burnt soils was more stable, but had a higher degree of stochasticity in unburnt rhizosphere soils.

Summary: This study explored the impact of cover crop management on weed biomass and crop productivity in subsequent crops, finding that the composition of cover crops, termination methods, and soil resource availability all played a role.
