Mountain areas are biodiversity hotspots and provide a multitude of ecosystem services of
irreplaceable socio‐economic value. In the European Alps, air temperature has increased at …

The mountain cryosphere of mainland Europe is recognized to have important impacts on a
range of environmental processes. In this paper, we provide an overview on the current …

The green wave hypothesis (GWH) states that migrating animals should track or 'surf'high-
quality forage at the leading edge of spring green-up. To index such high-quality forage …

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 …

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 …

Mountain ecosystems are sensitive and reliable indicators of climate change. Long-term
studies may be extremely useful in assessing the responses of high-elevation ecosystems to …

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 …

Summary 1 Nutrition influences most aspects of animal ecology: juvenile growth rates and
adult mass gain, body condition, probability of pregnancy, over‐winter survival, timing of …

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 …

Vital rates of large herbivores normally respond to increased resource limitation by following
a progressive sequence of effects on life‐history characteristics from survival of young, age …
