Evaluation of a rapid method for measuring lactate in the venous blood of ruminants
Veterinary Record, EarlyView.Abstract Background In cattle and small ruminants, blood lactate can predict recovery and survival in various diseases. Increased lactate concentration is associated with an unfavourable‐to‐poor prognosis. Different mobile rapid lactate measurement devices have been explored in different animal species.

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)

Wildlife Biology, EarlyView.Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species.
