Extended patchy ecosystems may increase their total biomass through self-replication

, 2017
Patches of vegetation consist of dense clusters of shrubs, grass, or trees, often found to be circular characteristic size, defined by the properties of the vegetation and terrain. Therefore, vegetation patches can be interpreted as localized structures.

The Inventory of Forest Carbon Stocks in the Province of Trento: some remarks on the sampling design and first comments on its results

Forest@, 2008
Multiple sampling designs are commonly used in forest inventory to combine information collected in very large first-phase samples using remote sensing (satelite or aerial images) with the field data collected on smaller sub-samples. In Italy, during the

Indicators of Pasture Digression in Steppe Ecosystems of Mongolia [PDF]

, 2012
The research shows that widely used key measures of vegetation structure (species diversity, projected cover and above-ground phytomass) are not always suitable as indicators of pasture degradation. Based on an analysis above-ground phytomass composition,
