Journal ArticleDOI
Do niche-structured plant communities exhibit phylogenetic conservatism? A test case in an endemic clade
Yoseph N. Araya,Jonathan Silvertown,David J. G. Gowing,Kevin McConway,Hans Peter Linder,Guy F. Midgley +5 more
TL;DR: The demonstration that clear niche segregation may occur among related species without PNC being detectable supports the hypothesis that hydrological niche responses are evolutionarily labile and demonstrates that phylogenetic analysis can be a poor guide to the process of community assembly.
Journal ArticleDOI
Hierarchical processes define spatial pattern of avian assemblages restricted and endemic to the arid Karoo, South Africa
TL;DR: In this paper, a quantitative, systematic analysis of the different bird communities spanning the Karoo was undertaken to examine contributions of broad and local-scale physical environmental and biotic factors to regional variations in the species composition, using multivariate statistical and spatial analytical tools.
Journal ArticleDOI
Photosynthetic responses of heliophilous Rhus species to environmental modification by invasive shrubs
TL;DR: Overtopped individuals of both indigenous species showed morphological and physiological changes generally consistent with widely reported shade effects, however, R. lucida showed an apparently rare combination of unchanged maximum photosynthetic rate and increased apparent quantum yield under shaded conditions.
Impacts, vulnerability and adaptation in key South African sectors: An input into the Long Term Mitigation Scenarios process
Guy F. Midgley,R. A. Chapman,Pierre Mukheibir,Mark Tadross,Bruce Hewitson,Stephanie J.E. Wand,Roland Schulze,T Lumsden,M Horan,Michele Warburton,Barney S. Kgope,B Mantlana,A Knowles,A Abayomi,Gina Ziervogel,R Cullis,A.K. Theron +16 more
Journal ArticleDOI
Long-term effects of elevated atmospheric CO2 on species composition and productivity of a southern African C4 dominated grassland in the vicinity of a CO2 exhalation.
William D. Stock,Fulco Ludwig,Carl Morrow,Guy F. Midgley,Stephanie J.E. Wand,Nicky Allsopp,Tina L. Bell +6 more
TL;DR: In this paper, the long-term effects of CO2 exhalation on a natural C4 dominated sub-tropical grassland in terms of ecosystem structure and functioning were investigated.
