Section B. Is local diversity a product of regional forces‚ local forces‚ or both‚ and how might we know? In ecology‚ the change in species diversity across space and time is one of the oldest studied subjects‚ however the underlying causes of many diversity patterns is under much debate (Field et al. 2001; MacArthur‚ 1972; Rosenzweig‚ 1995). How does diversity arise (Erwin 1991)? How is diversity distributed in space (Dean et al. 1997‚ Fonseca et al. 2000)? And how is diversity maintained

With regards to their morphology‚ lichens have three major forms which are described as crustose (crusty)‚ foliose (leafy) and fruticose (shrubby). Lichen ecology is also of significance in terms of habitat; their importance in nutrient cycling and the preventing erosion; indication of pollution as well as their characteristic
