The approach of the researchers has been to identify climate drivers of vegetation productivity on monthly timescales.

Loranty MM, Lieberman - Cribbin W, Berner LT, Natali SM, Goetz SJ, Alexander HD, Kholodov AL (2016) Spatial variation in vegetation productivity trends, fire disturbance, and soil carbon across arctic - boreal permafrost ecosystems.

«Our results suggest that model improvements need to be targeted at processes controlling vegetation productivity and respiration from the soil.»

Using maps of vegetation productivity during a severe drought that occurred in the southwestern United States in 2002, Stoner modeled what would be the deer and mountain lion distribution and abundance, should extreme drought become the norm.

Bieniek, P. A., U. S. Bhatt, D. A. Walker, M. K. Raynolds, J. C. Comiso, H. E. Epstein, J. E. Pinzon, C. J. Tucker, R. L. Thoman, H. Tran, N. Mölders, M. Steele, J. Zhang, and W. Ermold, Climate drivers linked to changing seasonality of Alaska coastal tundra vegetation productivity.

Climate change and direct human land - use pressure are likely to have synergistic impacts on desert ecosystems and species that may be offset, at least partly, by vegetation productivity and carbon sequestration gains due to rising atmospheric CO2.

They find that the projected future increases to growing season length result in greater vegetation productivity and biomass, though this plateaus at the end of of the 21st century.

The uncertain impact of elevated CO2 on vegetation productivity and biogeochemical cycling in deserts is an important source of contrasting projections of impacts and vulnerability for different desert regions and vegetation types.

They identified climate drivers of vegetation productivity on monthly timescales and computed the sensitivity index.

Studies including Wang's earlier work in Africa have shown that even small changes in soil moisture in drylands could be significant enough to cause large changes in vegetation productivity.

Vegetation productivity or leaf cover can, for example, be measured across continents from space while providing information about biodiversity levels on the ground.

However, dry - spell duration and warming trend effects on vegetation productivity may be at least partly offset by rising atmospheric CO2 effects on plants (Bachelet et al., 2001; Thuiller et al., 2006b), leading to sometimes contrasting projections for deserts that are based on different modelling techniques that either incorporate or ignore CO2 - fertilisation effects.

The general cooling and atmospheric circulation changes result in weaker peak river flows and vegetation productivity, which may raise issues of water availability and crop production.

Their projections show an increase to growing season length, vegetation productivity (outside of the southeastern US) and biomass, as well as increased plant water - use efficiency.They also find that vegetation feedbacks may increase warming in summer at higher latitudes and reduce summer warming at lower latitudes.
