Using the satellite-derived NDVI to assess ecological responses to environmental change.
Essential Biodiversity Variables
With the first plenary meeting of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) soon under way, partners are developing—and seeking consensus around—Essential Biod diversity Variables (EBVs) that could form the basis of monitoring programs worldwide.

Biodiversity redistribution under climate change: Impacts on ecosystems and human well-being
The negative effects of climate change cannot be adequately anticipated or prepared for unless species responses are explicitly included in decision-making and global strategic frameworks, and feedbacks on climate itself are documented.
The Normalized Difference Vegetation Index (NDVI): unforeseen successes in animal ecology
This review highlights the latest developments associated with the use of the Normal- ized Difference Vegetation Index (NDVI) in ecology. Over the last decade, the NDVI has proven extremely useful in…

The results suggest that attempts to forecast how warmer winters and springs will affect animal population dynamics and life histories in alpine environments should consider factors influencing the rate of changes in primary production during green-up and the timing of vegetation onset.

An increasing NAO results in a spatially more variable phenology, offering migrating deer an extended period with access to high-quality forage leading to increased body mass, and the importance of incorporating spring as well as the interaction between winter climate and topography when aiming at understanding how plant and animal respond to climate change.

Using national crop and livestock production records from 1961-2003 and satellite-derived data on pasture greenness from 1982-2003 we show that the productivity of crops, livestock, and pastures in…

This study explored how climate and vegetation onset (satellite-derived Normalized Difference Vegetation Index data) determined individual performance in three reindeer populations, and found an earlier onset positively affected the body mass of calves born the following autumn.
