Topography can create substantial environmental variation at fine spatial scales. Shaped by slope, aspect, hill-position and elevation, topoclimate heterogeneity may increase ecological diversity, and act as a spatial buffer for vegetation responding to climate change. Strong links have been observed between climate heterogeneity and species diversity at broader scales, but the importance of topoclimate for woody vegetation across small spatial extents merits closer examination. We established w...

Summary The rugged topography of the Cape Floristic Region (CFR), South Africa, is frequently invoked to explain the spectacular radiation of the Cape flora, but the mechanisms involved remain unclear. Where recent authors emphasize the importance of elevation gradients as stimuli for ecological speciation, earlier workers stressed the role of topography as an isolating mechanism, particularly in montane lineages. Using six Cape plant lineages, we tested whether elevation niches are phylogenetic...

Abstract Since some speciation mechanisms are more likely to generate morphological disparity than others, the general failure of vascular plant taxonomists to recognize cryptic diversity may bias perceptions about speciation process in plants. While the exceptional floristic richness of the South African Cape has largely been attributed to adaptive divergence (‘ecological’ speciation), a combination of climatic dynamism and complex topography has likely provided ample opportunities for ‘non-eco...

abstract Understanding the ecology and evolution of the hyper-diverse Cape flora is dependent on developing anunderstanding of its component parts, best epitomized by the Cape floral clades that have diversified andare largely endemic to the region. Here we employ a new dated phylogenetic hypothesis for the sedgegenus Tetraria, one of the smaller Cape floral clades, to develop an understanding of timing and ratesof diversification in the group. Specifically, we test whether diversification in Tetraria ...

Abstract Soil organic matter (SOM) is a major pool within the global carbon cycle and understanding its composition (and compositional variability) is critical for predicting its response to future climatic change. Arid and semi-arid regions are typified by relatively low soil organic matter concentrations, but their vast area means that they still represent an important component of the global soil carbon pool. Recent studies have demonstrated the potential of pyrolysis–gas chromatography/mass ...
