Fig.1: Ecosystem Functional Types (EFT) of temperate South America based on Moderate Resolution Imaging Spectroradiometer Enhanced Vegetation Index (MODIS-EVI) dynamics (Alcaraz-Segura et al. 2013). The map shows the EFTs of the 2001–2008 period.
Ecosystem Functional Type (EFT) is an ecological concept to characterize ecosystem functioning. Ecosystem Functional Types are defined as groups of ecosystems or patches of the land surface that share similar dynamics of matter and energy exchanges between the biota and the physical environment.[1][2][3] The EFT concept is analogous to the Plant Functional Types (PFTs) concept, but defined at a higher level of the biological organization. As plant species can be grouped according to common functional characteristics, ecosystems can be grouped according to their common functional behavior.
One of the most used approaches to implement this concept has been the identification of EFTs from the satellite-derived dynamics of primary production,[1][2] an essential and integrative descriptor of ecosystem functioning.[4]
