Effects of Climate Change on Ticks and Tick-Borne Diseases in Europe
Figure 3
The vegetation-derived
clusters as recognized over the western Palaearctic. The image was obtained
from a yearly series of monthly satellite images, capturing the Normalized
Difference Vegetation Index (NDVI): a measure of the photosynthetic activity of
the vegetation. These images were subjected to a cluster analysis according to
the monthly NDVI features to obtain 10 categories (category 1 is water and not
displayed in the picture). (Estrada-Peña et al. 2006 [48], with permission from Medical and Veterinary Entomology).
