The lack of long-term records of productivity is a critical limitation to the study of ecosystem dynamics. Annual rings, a measure of growth in woody species, are a useful tool to document ecosystem dynamics. Time series of the Normalized Difference Vegetation Index (NDVI) provide estimates of ecosystem productivity through satellite-derived data on the fraction of photosynthetic active radiation absorbed by vegetation. In the Patagonian steppes, we relate changes in NDVI to interannual… 
Lake Fluctuations, Plant Productivity, and Long-Term Variability in High-Elevation Tropical Andean Ecosystems
Abstract Environmental trends and ecosystems' ranges of variability are little known in tropical very high elevation Andean ecosystems (above 4400 m a.s.l.). We combined satellite image analyses and
Growth variability and contrasting climatic responses of two Quercus macrolepis stands from Southern Albania
Key messageContrasted response of Quercus macrolepisgrowth to climate conditions during summer months indicated increased climate-related control of tree growth at high elevation site modulated by

Mediterranean dwarf shrubs and coexisting trees present different radial-growth synchronies and responses to climate
TLDR
Local conditions are also major drivers of growth in Mediterranean dwarf shrubs as indicated by the stronger asynchrony in ring formation of these species as compared with coexisting trees, particularly in cold sites.

CONTROLS OF GRASS AND SHRUB ABOVEGROUND PRODUCTION IN THE PATAGONIAN STEPPE
TLDR
ANPP association with climatic variables in the Occidental District of the Patagonian steppe shifted from precipitation alone to pre- cipitation and temperature when the temporal scale of analysis changed from annual to annual.
Ecosystem responses to changes in plant functional type composition: An example from the Patagonian steppe
Abstract. Grass cover along a grazing intensity gradient in Patagonia decreases, whereas bare soil and shrub cover increases. Our objective was to study the effect of a change in the dominant plant
PATTERNS AND CONTROLS OF PRIMARY PRODUCTION IN THE PATAGONIAN STEPPE: A REMOTE SENSING APPROACH†
We took advantage of regional gradients to study the spatial relationships between aboveground net primary production (ANPP) and climate in the Patagonian steppe of South America. We explored the
Relations between NDVI and tree productivity in the central Great Plains
Remotely sensed Normalized Difference Vegetation Index (NDVI) is a good measure of photosynthetic activity at landscape scales, and can be used to estimate productivity. Our research demonstrates
