Fig. 1: Graphical interpretation of the forest ecosystem function proxies used in this study.
From: Effectiveness of the world network of biosphere reserves in maintaining forest ecosystem functions

Variations in vegetation vitality assessed via gross and net primary productivity as well as via the enhanced and normalized difference vegetation index; Variations in temperature regulation capacities via hot day land surface temperatures. Variations in precipitation and water regulation via evapotranspiration and variations in ecosystem extents and state via forest patch connectivity.
