Over the last two centuries overhunting, anthropogenic barriers and habitat loss have
disrupted many ungulate migrations. We review the literature on ungulate migration …

More and more studies are demonstrating that populations of animals‐from herbivores to top
predators, vertebrates and invertebrates‐are limited by their food, and that the availability of …

There has been a recent surge of interest in remote sensing and its use in ecology and
conservation but this is the first book to focus explicitly on the NDVI (Normalised Difference …

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 …

This review highlights the latest developments associated with the use of the Normalized
Difference Vegetation Index (NDVI) in ecology. Over the last decade, the NDVI has proven …

The forage-maturation hypothesis (FMH) states that herbivores migrate along a
phenological gradient of plant development in order to maximize energy intake. Despite …

Animal migration has long intrigued scientists and wildlife managers alike, yet migratory
species face increasing challenges because of habitat fragmentation, climate change and …

The forage maturation hypothesis (FMH) proposes that ungulate migration is driven by
selection for high forage quality. Because quality declines with plant maturation, but intake …

Time can be a limiting constraint for consumers, particularly when resource phenology
mediates foraging opportunity. Though a large body of research has explored how resource …

Seasonal patterns of climate and vegetation growth are expected to be altered by global
warming. In alpine environments, the reproduction of birds and mammals is tightly linked to …
