Land cover has been evaluated and classified on the basis of general features using reflectance or digital levels of photographic or satellite data. One of the most common methodologies based on CORINE land cover (Coordination of Information on the Environment) data, which classifies natural cover according to a small number of categories. This method produces generalizations about the inventor...

Synthetic aperture radar (SAR) is one of the most promising remote sensors to map forest carbon. The unique spaceborne and longwavelength SAR data currently available are L-band data, but their relationship with forest biomass is still controversial, particularly for high biomass values. While many studies assume a complete loss of sensitivity above a saturation point, typically around 100 t.ha...

Unfavourable soil conditions frequently limit tree regeneration in mountain forests on calcareous bedrock. Rocky, shallow organic soils on dolomite pose a particular problem for tree regeneration due to commonly restricted water and nutrient supplies. Moreover, an often dense layer of understorey vegetation competes for the limited resources available. Hence, an array of interacting factors imp...

Ecological data about three free-ranging groups of C. penicillata (black-pincelled marmoset) were observed between March and December 1996, in one cerradão patch (in the Ecological Reserve of Brazilian Institute of Geography and Statistics, RECOR) and two patches of dense cerrado (one in the RECOR and another in the Botanical Garden of Brasília, JBB), situated in the APA (area of environmental ...

The Pangkal Babu Mangrove Forest has an important role in a fish habitat that is closely related to the livelihoods of fishermen so it overall economic relationship. This study aims analyze condition mangrove forests, triangulation relationship between forests and resources, community's economy as well forms local wisdom protecting preserving forests. research was conducted forest area, Tungkal...

r(A) = \V\-k(A), (2) where k(A) is the number of connected components of the graph with vertex set V and edge set A (including isolated vertices). It can immediately be seen from the above that the number of forests of a graph is equal to the value of the Tutte polynomial at the point (2,1). The Tutte polynomial contains many other invariants of fundamental importance in fields as diverse as st...

From analysis of published global site biomass data (n = 136) from primary forests, we discovered (i) the world's highest known total biomass carbon density (living plus dead) of 1,867 tonnes carbon per ha (average value from 13 sites) occurs in Australian temperate moist Eucalyptus regnans forests, and (ii) average values of the global site biomass data were higher for sampled temperate moist ...
