Our understanding of ungulate migration is advancing rapidly due to innovations in modern
animal tracking. Herein, we review and synthesize nearly seven decades of work on …

Migration of ungulates (hooved mammals) is a fundamental ecological process that
promotes abundant herds, whose effects cascade up and down terrestrial food webs …

As human activities expand globally, there is a growing need to identify and mitigate barriers
to animal movements. Fencing is a pervasive human modification of the landscape that can …

Global declines in wildlife migrations have prompted new initiatives to conserve remaining
migratory behaviors. However, many migrations have already been lost. Important attempts …

BACKGROUND Fences are one of the most widespread manmade features in nature,
constituting an artificial limitation to the movement of wildlife. To date, their effects on wildlife …

Migratory ungulates are thought to be declining globally because their dependence on large
landscapes renders them highly vulnerable to environmental change. Yet recent studies …

Background Small unoccupied aircraft systems (UAS) are replacing or supplementing
occupied aircraft and ground-based surveys in animal monitoring due to improved sensors …

Modern tracking technology has facilitated a novel understanding of terrestrial mammal
movement while revealing that movements are being truncated and lost. The first step …

Formally protected areas are an important component of wildlife conservation, but face
limitations in their effectiveness for migratory species. Improved stewardship of working …

Fine‐scale movement data has transformed our knowledge of ungulate migration ecology
and now provides accurate, spatially explicit maps of migratory routes that can inform …
