<p>The Amazon rainforest is among the most vital ecosystems on earth, holding about a quarter of the global terrestrial carbon sink. Since 2005, three 100-year return period droughts have occurred, the likes of which have the potential to turn the forest from a carbon sink to a carbon source. Monitoring the Amazon is essential to

The Vegetation Index and the Study of Vegetation Dynamics
1989The presentation reviews the basic principles supporting the derivation and analysis of vegetation indices from spectral data. The relationships between the normalized difference vegetation index and the vegetation characteristics is discussed, with emphasis upon dynamic processes important in biomass accumulation. Since time-series of vegetation index

It is almost dogma that the boreal forest in North America is a fire-dependent forest, yet ecologists often do not consider in any technical detail how forest fires produce effects on individual plants and on plant populations. Consequently, the causal connection between the behaviour of fire and its ecological consequences is poorly understood.

On the dynamics of vegetation: Patterns of environmental and vegetational change
Vegetatio, 1978Ecological succession theory deals with temporal change in biological communities. It consists largely of generalizations based on temporal sequences inferred from spatial ones. The predictive content of the theory is low, since predictions are derived from unconditional trends rather than conditional laws.

Vegetation dynamics induced by phreatophyte–aquifer interactions
Journal of Theoretical Biology, 2007The dynamics of phreatophyte vegetation are strongly coupled to those of the shallow phreatic aquifers from which phreatophytes extract water. Vegetation is able to influence the depth of the water table, which, in turn, can induce stress in vegetation.

Vegetation dynamics or ecosystem dynamics: Dynamic sufficiency in succession theory
Vegetatio, 1980Recently several authors have claimed that long term vegetation change, at least in the case of forest ecosystems, can usefully and quite accurately be described by stationary Markov chain models (Anderson, 1966; Waggoner & Stephens, 1970; Horn, 1974, 1975a, 1975b, 1976) or their deterministic counterpart, coupled differential equation models (Shugart ...

Vegetation Dynamics as a Tool for Detecting Clandestine Graves
Journal of Forensic Sciences, 2012Abstract: The burial of a body can affect plant communities through mechanical disturbance and nutrient balance alteration. We performed an experimental trial using five swine carcasses buried in an open site in Italy. Vegetation dynamics was monitored recording monthly every plant individual on a regular sampling grid during 1 year on the graves, on ...

Vegetation and Ecosystem Dynamics
2009Within the Mediterranean region a number of distinctive vegetation communities can be recognized, comprising some 25,000 species, of which about 50 per cent are endemic. Broadly defined, these originated with the establishment of a mediterranean-type climate about 3.2 million years ago, since when they have been subject to the vicissitudes of glacial ...
