Assessing how environmental changes affect the distribution and dynamics of vegetation and animal populations is becoming increasingly important to terrestrial ecologists. However, until recently linking climate, vegetation and wildlife has not been an easy task, partly because traditional field ecological data on plants are generally collected at small spatial scales for only a few species.

Remote sensing data and NDVI (Normalised Difference Vegetation Index) have recently changed this situation, and given ecologists a promising way to couple vegetation with herbivore distribution, movement, performance and dynamics.

In this talk Dr. Pettorelli will discuss how NDVI can help quantify the relationships between vegetation dynamics, animal distribution, animal density, seasonal movements and individual performance in various ecosystems (spanning from tropical, to semi-desertic to arctic) at multiple spatial and temporal scales.
