Summary Understanding the movement ecology of threatened species is fundamental to improving management and conservation actions for their protection, mainly during pre-adult stage particularly when a subject population reinforcement or reintroduction projects. An example case Cinereous Vulture Aegypius monachus on Iberian Peninsula, an endangered that has been reintroduced in different regions last two decades. Here, we explore differences between spatial Vultures, according age-class, sex, season (breeding non-breeding). We used GPS-tag data from 51 individuals into Catalonia (north-east Spain) describe use space, i.e. home-range size, core area, minimum convex polygon (MCP) patterns, cumulative distance, maximum displacement, daily dispersal, annual dispersal. Our study showed significant variation space patterns among birds influences age, season. Age was most influential factor, determining range areas patterns. Similar other vulture species, home increase with subadult vultures exhibiting larger ranges than young first year, juveniles, immature birds, but MCP measures were juveniles. Movement also influenced by juveniles making longer movements, followed immatures subadults (with similar values), shorter movements year life. Overall, males made explored smaller foraging females. Season had important effect dispersal breeding period (February–August). findings fill knowledge gap regarding behaviours information will enable improvement decisions.

Unsustainable fossil fuel emissions have prompted a global shift towards renewable energy sources, such as wind. This has led to strong expansion of wind power generation infrastructures, often conflicting with biodiversity conservation. Relatively large flying animals, birds and bats, frequently been reported collide turbines, resulting in casualties that can depress population size lead local extinctions. Migratory species move across continents through their year-round displacements may be especially at risk. We comprehensively assessed turbine exposure for colonial migratory raptor European conservation interest, the lesser kestrel Falco naumanni, based on distribution >1800 colonies GPS-tracking dataset (>350 individuals) three distinct biogeographical populations (from Iberian, Italian, Balkan peninsulas). 26 % least one within foraging areas around colony sites, Italian being most The main network protected areas, Natura 2000 network, failed mitigate potential negative impact turbines breeding populations. revealed was negligible African non-breeding (Sahel region), particularly high during migration, lower Iberian individuals but not ones.

Abstract The rapid expansion of wind power energy has direct negative impacts on biodiversity, notably avifauna through collisions with turbines. A better understanding the collision causes is key to improving mitigation efforts. Collisions are result a combination environmental factors that increase bird sensitivity and/or exposure collisions. To date, potential risk have mostly been assessed individually, in few species interest at small spatiotemporal scales, despite multifaceted nature risk. fill this gap, we used for first time data from automatic detection systems (optic automatically detect and monitor birds vicinity turbines) simultaneously assess effects behavioural (here, estimated as presence zone) frequency which use zone). We analysed 205,867 trajectories recorded between 2018 2023 11 French facilities. obtained results similar previous studies relying other methods (GPS, observations). Results suggest was higher during periods high activity (first hours daylight migrations). They also may conditions reduce birds' visual perception turbines (high nebulosity, low visibility rotor speeds) influence flight height temperatures speeds). found nonsynchronicity peaks, highlighting importance considering both drivers when investigating However, our show variability species, behaviours sites should be addressed future clarify relationships risk, behaviour. Policy implications . Data promising non‐invasive approach requires human logistical resources develop more comprehensive strategy. can valuable biodiversity stakeholders highlight locally sensitivity, avoid installing sensitive areas or adjust system settings.

This research plunges into the rapidly growing radar technology in medical sector, putting emphasis on its possibility to revolutionize elderly care and health monitoring among aging global population. Based a systematic literature review rigorous bibliometric analysis, we discuss application healthcare, focusing potential for non-invasive, high-accuracy diagnosis continuous patient monitoring. Our findings highlight critical harmony between advances machine learning, artificial intelligence, data analytics, which open door smart healthcare solutions. These advancements will improve early disease detection, fall risk prevention, real-time monitoring, resulting quick responses. study endeavors offer useful knowledge researchers, practitioners, policymakers who are working towards use of better context demographic changes that world is experiencing terms an ageing population by mapping current landscape, identifying existing trends gaps, proposing future direction research.
