The loss of biodiversity is a significant ecological problem, and an important component of global environmental change (Ehrenfeld, 1972; Soulé, 1986; Wilson, 1988a; Lovejoy, 1988; NRC, 1992). The major cause of biodiversity loss is human action, primarily land-use that alters habit

The most direct cause of species extinction is the destruction of their habitat, but even in p

A conservative estimate of the magnitude of fungal biodiversity by Hawksworth (1991) suggests that less than 5% of the species have been described. Even in comparatively well-investigated countries as the Netherlands the fungal biodiversity can only be roughly estimat

Sascha Neumann,Philipp Sandermann9). Although plant communities of woodlands provide examples of varying ecological strategies (cf. Grime 1979), perhaps the most typical is the large number of stresstolerant species, species adapted to the low light intensity and the scarcity of mineral nutrients. They are mostly perennial species
