Using morphometrics to quantitatively differentiate African wild dog footprints from domestic dog footprints – a pilot study
Abstract Reliable population estimation and species inventories are important for wildlife conservation, but such estimations are often difficult due to unreliable identification of the species in question. Furthermore, for predator conflict resolution, it is essential to be able to reliably identif...
