Comparing leukocyte‐ and thrombocyte‐rich fibrin and autologous grafts for the treatment of experimentally induced wounds in the tarsometatarsus of chickens

Veterinary Record, EarlyView.
Abstract Background Managing open wounds in birds is challenging. This study compared leukocyte‐ and thrombocyte‐rich fibrin (L‐TRF) and autologous grafts for treating wounds in the tarsometatarsus of chickens. Methods Full‐thickness wounds were experimentally induced in the tarsometatarsus of 23 healthy adult chickens.

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects

Wildlife Biology, EarlyView.
Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)
