Summary: Site selection bias can occur when researchers choose to monitor animals in locations that have high abundance, occupancy or quality. This can lead to an inaccurate representation of the overall population dynamics. Three potential pitfalls of site selection bias include regression to the mean, preferential sampling, and the missing zero effect.

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: The sea bass stock around the UK has declined rapidly over the past decade due to overfishing and low recruitment. To develop effective management strategies, understanding the factors that affect sea bass settlement on nursery grounds is important. An individual-based model has been used to investigate these factors, with simulations showing similarities to empirical data but also highlighting the need for further investigation into differences between modelled supply and observations.

Summary: This study investigated the fish assemblages on 629 rocky reefs along a 417 km coastline in southeastern Australia. The results showed that Chrysophrys auratus preferred to inhabit reefs near estuaries, with smaller size and higher abundance. The length and abundance of Nemadactylus douglasii and Pseudocaranx georgianus were not influenced by the proximity or size of estuaries. Regardless of the distance to estuaries, marine reserves had higher abundances and larger Chrysophrys auratus. The study highlights the importance of estuaries for sustaining coastal fisheries recruitment.

Summary: This study investigated the habitat selection of black grouse in the lowlands of Central Europe. It found that black grouse preferred undisturbed and heterogeneous habitats, far from dense forests, with wide sand heaths, natural grasslands, and intermixed bogs, diverse vegetation and food sources, and low density of (loose) shrub formations and solitary trees. Wetlands were extremely important in a landscape dominated by dry heaths and grasslands.

Summary: This study predicts the distribution patterns of juvenile largehead hairtail and identifies priority conservation areas for nursery grounds. A hierarchical Bayesian spatio-temporal model is applied to scientific survey data and geographic/physical variables. The study finds that dissolved oxygen, net primary production, and sea bottom temperature significantly affect the occurrence probability of the species. Three stable nursery grounds are identified in Zhejiang inshore waters, with the largest one located outside of protected areas. The study suggests including these areas in conservation planning for effective management.

Summary: The study shows that restoring suitable habitat in the Seine estuary in the Eastern English Channel can significantly increase spawning stock biomass and fishery catches of common sole. Restoring habitat quality has a greater effect than restoring habitat surface extent. Due to low connectivity between subpopulations, most of the benefits of local restoration remain regional, primarily impacting the subpopulation relying on the Seine nursery, with moderate spread to the entire Eastern English Channel.

Summary: A rigorous understanding of how environmental conditions affect population dynamics is crucial for species conservation. This study analyzed an 11-year dataset on puma space use, mortality, and reproduction to quantify the impacts of living in a fragmented landscape on individual survival and population dynamics. The results showed that long-term exposure to housing density led to increased mortality risk for female pumas, resulting in source-sink dynamics and reduced female survival in more developed areas. Habitat selection was found to be a better proxy for habitat quality in predicting source areas for large carnivores compared to time-of-day-independent habitat selection. The study highlights the importance of conserving high-quality source habitat and linking landscape conditions to population dynamics for effective conservation.

Summary: Understanding habitat use and reproductive biology of invasive species is crucial for predicting invasions and developing management plans. The study on rudd in the upper Niagara River revealed that emergent vegetation is the most important habitat factor associated with the presence of age-0 rudd, and their presence decreases as distance to the nearest wetland increases. The findings can be utilized to create predictive models of rudd invasion and guide early detection programs.

Summary: There is a clear gender difference between males and females of Macrobrachium amazonicum, with males more commonly found in larger size classes; males have a higher growth rate but shorter lifespan and higher mortality rate. Environmental changes and anthropic influences lead to system instability, resulting in shorter lifespan, faster growth rates, and smaller asymptotic sizes for both sexes.

Summary: Researchers have observed a modular pattern in the relationship between hermit crabs and gastropod shells, where the network can be divided into compartments with species interacting more within their own compartment. Different morphometric traits in hermit crabs influence their specialization levels, as hermit crabs of different sizes may require different types of shells for optimal interaction.

Summary: The early larval stages of Lysmata ankeri and L. bahia were described, compared, and illustrated, providing valuable insights into their post-embryonic development and evolutionary history. Ovigerous specimens from the coast of southeastern and northeastern Brazil were used for this study. Unique features were observed in the larvae of L. ankeri and L. bahia, which were not found in other analyzed species, such as a pair of simple setae on the third pleonal somite in zoea I and more than 11 setae on the uropod exopod. Similar characteristics were found in species from different clades of the Lysmata-Exhippolysmata complex, allowing for the identification of early stages of Lysmata larvae. Further research is needed to confirm phylogenetic patterns and the significance of other larval characters for a better understanding of the evolutionary history of this group.

Summary: Thoe Bell, 1836 is a type of amphiamerican small spider crab with cryptic habits, which has rare records in the literature and carcinological collections. The taxonomy of the known species in the genus has been revised, and a phylogenetic reconstruction based on mitochondrial markers supports the monophyletic status of Thoe and suggests a radiation of the genus from the western Atlantic to the eastern Pacific.
