Summary: Passive integrated transponder devices (PIT tags) are reliable for individual identification in Eurasian beavers, but the retention rate of very high frequency (VHF) transmitters and bio-loggers is relatively low, particularly for temperature and heart rate loggers.

Summary: Moors in western European landscapes are important habitats for nature conservation, but many have been degraded. Beavers are seen as a potential factor for rewetting these habitats. Research shows that the development of beaver populations in moor habitats can be closely tracked through analyses of digital orthographical aerial photographs (DOPs).

Summary: Territory acquisition and pair compatibility are essential for the fitness of territorial animals. In Eurasian beavers, competitive ability is crucial for territory acquisition, while mate compatibility is generally less important. The study suggests a trade-off between territory acquisition and pair compatibility in saturated populations.

Summary: Competition and predation are key factors shaping interspecific coexistence in wildlife communities. This study used camera trapping to investigate the overlap of activity rhythms between the Eurasian beaver and its potential competitors and predators. The results showed that the beaver displayed mostly crepuscular behavior and avoided overlapping with the activity of predators.

Summary: The study found that tagging Eurasian beavers can lead to a reduction in daily body weight but the specific mechanisms behind this effect are unclear. Tag weight, number of tagging days, and season did not have a significant impact on the body weight change of tagged animals. The detrimental effects of tagging have implications for animal welfare and data bias, emphasizing the importance of careful consideration in tag use.

Summary: This study conducted research on 90 Eurasian individuals and analyzed their skull data through computed tomography images. Four distinct skull types were identified, providing guidance for orthodontic surgery in the Eurasian population.

Summary: This study summarizes the foraging behavior of beavers in commercial and natural forests in the Czech Republic. Beavers prefer willow, poplar, and hazel as their food sources, but they also use commercial tree species like oak, causing economic losses in forestry. The preference for different trunk diameters and distances from water varies in different types of forest stands.

Summary: The Eurasian beaver is distributed in at least 32 European countries, with most countries protecting the species but allowing hunting when the population is strong. In Poland, where the beaver population is large, it is only partially protected. The study compared the population trends of beavers in Poland (protected) and Belarus (hunted) from 2004 to 2019. The results showed that the population in Poland increased 3.5 times during this period, while in Belarus it only increased by 20%.

Summary: This study investigates factors influencing tree species selection by Eurasian beavers in forests, aiming to provide practical proposals for protecting commercial tree species while maintaining high beaver populations. The study finds that beavers prefer deciduous softwoods over commercial species as food. Planting dense softwood stands at a certain distance can reduce damage to commercial tree species.

Summary: The reintroduction of Eurasian beavers in England has potential benefits for flood alleviation and biodiversity, but faces opposition. One area of controversy is the impact on fish and fishing. By using Q-Methodology, researchers found three nuanced and contrasting perspectives among the angling community in the reintroduction areas. To address potential conflicts, management themes should include open dialogue across sectors, research into beaver-fish relationships, and empowerment for individuals to respond to negative impacts.

Summary: Body size and testicular measurements are important parameters for evaluating breeding quality. Age significantly affects body and testicular measurements in Arabian bucks, with the highest correlation coefficients observed between body weight and various traits, as well as body condition score and body measurements, showing the potential for these measurements to be used in selecting males for reproduction.

Summary: The study found that all beavers in the three populations tested were in good physical condition, showed low levels of disease or parasite exposure, and did not carry any non-native diseases or parasites of concern. This suggests that beavers are successfully adapting to British landscapes and are not significant reservoirs of zoonotic diseases.

Summary: This paper presents a low-power continuous patient monitoring method that improves clinical practice and patient outcomes by collecting biological impedance measurements. The method tracks the activity level and body states of patients, providing new insights into their status and assisting in remote monitoring of heart failure patients.

Summary: With increasing technology and knowledge, non-invasive methods for monitoring wildlife, such as identifying and ageing Eurasian beavers from their tail, are becoming more important. This study found that individual identification using tail patterns was 100% accurate across different distances, indicating its potential as a non-invasive monitoring method. However, the method of ageing beavers based on tail color was found to be inaccurate.
