Steppe Eagle Population Structure Genetic Study: is There Hope for the Endangered Species?
Пернатые хищники и их охрана, 2023 For centuries, Steppe Eagle (Aquila nipalensis) had been the most numerous Palearctic Aquila species, but nowadays it has been decreasing in numbers progressively, so in 2015 the IUCN changed the species status to “endangered”.

Survey for Hemoparasites in Imperial Eagles (Aquila heliaca), Steppe Eagles (Aquila nipalensis), and White-tailed Sea Eagles (Haliaeetus albicilla) from Kazakhstan [PDF]
Journal of Wildlife Diseases, 2004 Prevalence of hemoparasites has been investigated in many avian species throughout Europe and North America. Basic hematologic surveys are the first step toward evaluating whether host-parasite prevalences observed in North America and Europe occur elsewhere in the world. We collected blood smears from 94 nestling imperial eagles (Aquila heliaca), five

Advanced Materials Interfaces, EarlyView.Spin‐coated films of the conjugated polymer F8T2 (poly (9,9‐dioctylfluorene‐alt‐bithiophene)) generate superoxide at the film‐medium interface, enabling precise delivery of reactive oxygen species (ROS) as visible‐light “ROS patches.” Coated surfaces drive rapid, localised cytotoxicity in MCF7 cancer monolayers under white light, providing a reagent ...

Eagle Nesting Groups in the Important Bird Area “Donyz-Tau cliff faces” in 2022
Пернатые хищники и их охрана, 2023 The Important Bird Area (IBA) “Donyz-Tau cliff faces” (KZ019), with an area of 387,110 hectares, has been allocated by I.V. Karyakin (2008) based on survey results in 2003–2006. Survey showed several globally threatened and biome-specific species nesting

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Monitoring mercury across the National Wildlife Refuge System using a biosentinel approach
The Journal of Wildlife Management, EarlyView.We measured mercury concentrations in 1,356 dragonfly larvae collected from 30 National Wildlife Refuges across the United States and found wide variability among refuges, spanning the full range reported for other protected lands. Using a management‐focused mercury impairment index, 80% of refuges contained sites classified as moderate or higher risk.
