The introduction of exotic plants can have large impacts on ecosystem functions such as soil nutrient cycling. Since these impacts result from differences in traits between the exotic and resident species, novel physiological ...
How much evolutionary history in a 10x10m plot?
We use a fully dated phylogenetic tree of the angiospermfamilies to calculate phylogenetic diversity (PD) in four South African vegetation types with distinct evolutionary histories. Since the branch length values are in ...
The recent fire history of the table Mountain National Park and implications for fire management
(Open Journals Publishing, 2008)
This paper provides an assessment of fire regimes in the Table Mountain National Park over the past four decades. We compiled a GIS database of all fires between 1970 and 2007 and analysed the fire regime in terms of the ...
