Climate change is a defining element of the current ecological landscape, with
consequences ranging from global to local environments. One of the first indices of the …

Resource tracking, where animals increase energy gain by moving to track phenological
variation in resources across space, is emerging as a fundamental attribute of animal …

The cryosphere (including, snow, glaciers, permafrost, lake and river ice) is an integral
element of high mountain regions, which are home to roughly 10% of the global population …

Ungulate migrations are assumed to stem from learning and cultural transmission of
information regarding seasonal distribution of forage, but this hypothesis has not been …

The impacts of environmental predictability on the ecology and evolution of animal
movement have been the subject of vigorous speculation for several decades. Recently, the …

In terrestrial systems, the green wave hypothesis posits that migrating animals can enhance
foraging opportunities by tracking phenological variation in high-quality forage across space …

The green-up of vegetation in spring brings a pulse of food resources that many animals
track during migration. However, green-up phenology is changing with climate change …

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 …

Abstract The Green Wave Hypothesis posits that herbivore migration manifests in response
to waves of spring green‐up (ie green‐wave surfing). Nonetheless, empirical support for the …

In the 4.5 decades since Altmann (1974) published her seminal paper on the methods for
the observational study of behaviour, automated detection and analysis of social interaction …
