Summary: Fenced ecosanctuaries are effective in creating pest predator-free habitat for species with predation as a limiting factor, but our research found a lack of high-quality habitat around many fenced ecosanctuaries, especially outside the fence. Managers deciding on ecosanctuary locations should consider both the ecosystems within and surrounding the site, and the connectivity between the two. Lessons learned from fenced ecosanctuaries in New Zealand are likely applicable to other areas where the use of fenced ecosanctuaries for predation-sensitive species is emerging.

Summary: The study investigates American alligators' movement behaviors in a managed freshwater marsh ecosystem of the Florida Everglades using satellite telemetry, revealing that individual alligators did not change space use across seasons, but some showed lower movement activity and higher nitrogen isotopic values in the dry season, potentially due to concentrated prey during marsh dry down. Alligators may be using canals for foraging and shallow sawgrass habitats for basking, indicating that ongoing restoration of water inflow will likely impact alligators' distribution and movement behavior.

Summary: Understanding the role of adjacent habitats and predator abundance in controlling aphids in soybean fields is important for improving pest control in agriculture. This study found that hoverflies and ladybeetles were the most common predators moving into soybean during a soybean aphid outbreak, and their movement was influenced by the presence of aphids. Annual crops, such as wheat and canola, were found to have more predators than perennial crops or woody vegetation. The study suggests that adjacent wheat and canola fields contribute more predators for aphid control in soybean compared to adjacent alfalfa or woody vegetation.

Summary: This study found that the anti-predatory effect of snake sloughs in bird nests varies with different types of habitats. Snake sloughs in bird nests can reduce nest predation and serve as an anti-predator strategy. However, the effectiveness of snake sloughs in nests may depend on the species of nest predators and food resources in the habitat, which does not apply to all types of habitats.

Summary: Animal movement data is collected with devices like sensors and collars to monitor animal behavior, understand their relationship with the environment, and guide decision-making for environmental preservation and conservation actions. Current research focuses on identifying behavioral patterns and group formation, but lacks a unified solution for analyzing individual animal behavior and social interactions. This study presents a framework that uses trajectory analysis and association rule mining to determine the relationship level between animals, their social interactions, and their interactions with other environmental factors based on their movement data.

Summary: The global population of European eel is declining due to migration barriers in rivers. Bypass solutions are often constructed without sufficient knowledge of swimming behavior. This study used acoustic telemetry to track downstream-migrating silver eels and found differences in swimming behavior between downstream and upstream movement. The study provides important knowledge for designing effective bypass solutions for eels at migration barriers.

Summary: Atlantic goliath grouper is the largest grouper species in the Atlantic and has high site fidelity and limited movement range. The population in US waters declined significantly by 1990, leading to a harvest ban. Although the south Florida population has grown, the extent of recovery is uncertain. Despite this, limited recreational harvest has been approved. A recent study using acoustic telemetry and positioning solver revealed the fine-scale habitat use of three juvenile goliath groupers, showing high site fidelity and diel habitat use pattern.

Summary: In this study, intraspecific differences in outmigration phenology and straying prevalence in brown trout were investigated. The patterns of outmigration and return to freshwater differed between rivers, as did the factors affecting these outcomes. There was also a river-specific link between outmigration phenology and the likelihood of returning. The study suggests that the costs and benefits of autumn migration and straying depend on an individual's home river.

Summary: Habitat heterogeneity is an important factor influencing species distribution, and for harbour porpoises, their distribution is linked to prey availability. This study investigated the distribution and foraging behavior of harbour porpoises on a micro-scale using passive acoustic dataloggers in a high-density area in southern Sweden. The results revealed spatial preference at a small scale, with significant differences observed between sites that were only a few hundred meters apart. The study also found that porpoise activity followed a 24-hour cycle, with higher activity at night, and a 29.5-day cycle linked to the lunar cycle, with higher activity during full moon. The findings highlight the importance of considering micro-scale spatial distribution and foraging behavior in behavioral, management, and conservation studies and actions. The use of time series statistical methodology was shown to be informative and suitable for analyzing acoustic temporal data.

Summary: The global COVID-19 pandemic led to restrictions on people's movements in many jurisdictions, affecting recreational angling. After the restrictions were lifted, initial surveys suggested increased participation and altered angler demographics, but evidence remained limited. This study examines changes in angling interest, licence sales, and angling effort in different regions during the 'pre-pandemic,' 'acute pandemic,' and 'COVID-acclimated' periods. It suggests that efforts to retain younger anglers and provide more urban angling opportunities could increase overall participation levels and enhance resilience in recreational fisheries.

Summary: Sustainable management of lakes requires addressing ecological, economic, and social challenges, with a focus on achieving ecological improvement in a co-beneficial context. In-lake restoration measures can bring rapid ecosystem responses, especially when combined with circular economy practices. However, lake restoration approaches need to be carefully assessed to ensure they effectively address lake-specific problems, are cost-effective, and promote valuable ecosystem services.

Summary: Smartphone applications that serve as citizen science platforms can be used to collect data from recreational fisheries, providing an alternative to traditional survey methods. This study compared data from an electronic citizen science platform with an offsite web-based recall survey, and found that the data were consistently similar for certain fisheries, but the recall survey estimates were consistently higher for others. This suggests that the applicability of smartphone applications as citizen science platforms may be fishery-specific, and systematic bias may occur.
