Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

Wildlife Biology, EarlyView.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

A Case Report on Rehabilitation of the Asiatic Black Bear (Ursus thibetanus ussuricus) in the Wild 亚洲黑熊 (Ursus thibetanus ussuricus) 野外放归野化案例报告

Wildlife Letters, EarlyView.
Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.

Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China 气候变化下中国大兴安岭漠河地区猞猁潜在适宜区的变化

Wildlife Letters, EarlyView.
Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

High Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...
