The number of studies that have documented individual body-mass changes in free-ranging ungulates is limited, due to difficulties and risks associated with repeated captures of wild animals. We tested a remotely controlled platform scale on Alpine ibex (Capra ibex) and bighorn sheep (Ovis canadensis). Animals were baited onto the platform scale with salt, and weights were recorded by observers with binoculars and spotting scopes. We found this method was both accurate and effective and suggest that it has application for other studies on ecology and management of wild ungulates.

Abstract
The number of studies that have documented individual body-mass changes in free-ranging ungulates is limited, due to difficulties and risks associated with repeated captures of wild animals. We tested a remotely controlled platform scale on Alpine ibex (Capra ibex) and bighorn sheep (Ovis canadensis). Animals were baited onto the platform scale with salt, and weights were recorded by observers with binoculars and spotting scopes. We found this method was both accurate and effective and suggest that it has application for other studies on ecology and management of wild ungulates.File in questo prodotto:
