    The functional classification of EFTs developed by Paruelo et al. (2001) [1] and Alcaraz-Segura et al. (2006, 2013) [2] [3] uses time series of spectral vegetation indexes to capture the carbon gains dynamics, the most integrative indicator of ecosystem functioning. [4]

    [3] [4]: 5 [2]: 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows. [5] "Ecosystem processes" are the transfers of energy and materials from one pool to another. [2]: 458 Ecosystem processes are known to "take place at a wide range of scales". Therefore, the correct scale of study depends on the ...
