Summary: By combining GPS tracking and SIA analysis, insights into the wintering ecology and habitat use of the Corsican osprey population were gained. The study revealed that 50% of ospreys were resident while the other half were migratory, showing high plasticity in habitat selection across the Mediterranean basin. The integration of SIA and GPS/GSM tracking techniques proved effective in providing comprehensive information for ecological studies of migratory birds in aquatic environments.

Summary: Greater spear-nosed bats forage on patchily distributed balsa flowers, but do not commute together with group members. Close proximity among bats is more important during resting rather than foraging.

Summary: This study investigated the effects of Cyberlindnera jadinii supplementation on raccoon dogs during the winter fur-growing period. The results showed that supplementation improved growth performance, antioxidant activity, immune status, and intestinal microbiota. Among the concentrations tested, 1 x 10(9) CFU/g was the most effective level of supplementation.

Summary: Understanding the space requirements of animals and their behavior is crucial for conservation and resource management. Studying the space-use patterns of habituated primates using GPS devices provides detailed movement information, but these data may not accurately represent the animals' total movements. Through a 13-year dataset, we found that accurate home range estimation is possible with relatively small sample sizes and irregular sampling, as long as data is collected over extended time periods.

Summary: It has been found that Thin-billed Prions travel long distances during incubation to forage in the Patagonian Shelf or Polar Front waters, while during chick-rearing, they undertake variable duration trips and forage locally and inshore. They show a high flexibility in foraging areas, habitats, and trip durations.

Summary: By tracking the at-sea distribution and movements of breeding Ancient Murrelets, researchers found that foraging trips occurred in distant areas from the colonies, while resting and transit behaviors mainly took place throughout the night and during the day, respectively. These findings are crucial for marine conservation and identifying critical foraging habitat.

Summary: The migration strategies and activity patterns of the Chinese Sparrowhawk were investigated by fitting the birds with GPS satellite positioning devices. Results showed the species used stop-over sites during long-distance migration, and displayed distinct summer, winter, and stop-over home ranges. Migration speed and stop-over duration also showed regular patterns.

Summary: The study found that wetlands serve as important breeding habitats for waterbirds, but red foxes and invasive racoon dogs pose a threat to bird populations. The habitat utilization of red foxes and racoon dogs showed differences between day and night, with red foxes selecting saltmarshes to a greater extent.

Summary: Research on bar-tailed godwits during wintering in France shows that they exhibit contrasting foraging behaviors and distributions between day and night, with smaller foraging home ranges at night and a preference for seagrass beds during the day. This variability in space use highlights differences in habitat selection and the importance of considering the night distribution of birds in future management and conservation efforts.

Summary: Sex-specific foraging behavior was observed in common terns, with females resting less and foraging closer to the colony in more coastal waters compared to males. Males showed higher variability in their foraging distribution throughout the tide cycle and foraged more outside of protected areas. This study highlights the importance of considering sex-specific foraging distributions when assessing the impact of at-sea threats on seabirds.

Summary: This paper introduces a statistically and computationally efficient method for population-level analysis of home-range areas, based on autocorrelated kernel density estimation (AKDE). The method can account for variable temporal autocorrelation and estimation uncertainty. By applying the method to empirical examples, the study quantifies differences between species, environments, and sexes. The approach allows researchers to accurately compare different populations while maintaining statistical precision and power.

Summary: The study found that adult leatherback turtles foraging in the northeastern Gulf of Mexico mainly feed along the west Florida continental shelf, with some females traveling to nesting beaches in the Caribbean, while a few individuals forage in waters of the central Gulf of Mexico.Migration of adult females through the Yucatan Channel indicates its seasonal importance for Caribbean nesting assemblages.

Summary: This study examines how the interaction between resource density and exploitation efficiency influences home range size of wolves. The results show that exploitation efficiency plays a key role in determining home range size, with the impact of linear features diminishing in areas of higher resource density.

Summary: The study of home range utilization of rewilded animals is crucial for reintroduction management. Tracking 16 Milu deer individuals reintroduced to a nature reserve in China for one year, researchers found that seasonal changes significantly affected the home range and core areas of the deer. The study also revealed the resource use strategies of the deer in response to seasonal changes.
