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 is dynamic, i.e. it is involved in a continuous evolution. The rate of evolution is at its minimum in climax conditions, but in all other conditions it can range from very slow to fast. It is essential in phytocenological investigations to understand the processes involved in the evolution of vegetation, but such processes may be too slow ...

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.

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 ...

Nitrogen and Vegetation Dynamics in European Salt Marshes
2002In this paper we discuss the role of nitrogen in the vegation dynamics of European salt marshes. An overview is presented of various fluxes of nitrogen to and from salt marsh ecosystems. Our primary view is on European salt marshes. A nitrogen budget constructed for salt marsh ecosystems in the Wadden Sea area shows that N-influx rates via floodwater ...

Vegetation and vegetation dynamic of the Chilean littoral dunes
1992Las dunas litorales chilenas tienen su origen en procesos erosivos de tierras agrícolas, con el correspondiente acarreo de sedimentos por los ríos, hacia el mar. Este último disuelve los nutrientes y devuelve el suelo lavado, como arena, al litoral. Al secarse, los vientos se encargan de dispersarla. Por lo anterior, las dunas tienen mayor extensión en
