Superimposed on this is the episodic nature of major ecological changes, with naturally occurring floods and fires shaping the landform and distribution of vegetation communities, in addition to the more subtle successional changes. Spatial heterogeneity is another...

... 1982; Wiens 1989). In addition to spatial heterogeneity of structure, edges or ecotones contribute their own species assemblages that can be different to those present either side of the divide (Murcia 1995; Luck et al. 1999; Harper et al. 2005). This may increase diversity by attracting suites of edge...
