Phosphorous requirement of indigenous N-fixing legumes and rhizobial diversity in the low P soils of the Cape floristic region, South Africa
Soils of the Cape Floristic Region (CFR) vary in phosphorous (P) availability and legume species tend to be distributed in specific edaphic habitats. Eighteen indigenous CFR legume species were grouped as high-P, low-P, Pgeneralist and unclassified plants, by associating their distribution with …

Systematics of Ficinia clade (Cyperaceae)
… The clade has a centre of diversity in the Cape Floristic Region (CFR), where over 70% (113 species) of the species occur, with several taxa dispersed into alpine areas of Africa, and to Australasia, Europe and the Americas. This study aims to infer the phylogenetic relationships and …

A systematic study of the South African genus Prionium (Thurniaceae)
… widespread within the Fynbos biome in the Cape Floristic Region (CFR) with scattered populations into the Maputaland-Pondoland Region (MPR). This study of the systematics of the genus Prionium investigates whether this old lineage comprising of a single extant species P. serratum, is …

Rhizobia diversity and their effect on the distribution of indigenous legumes in the Cape Floristic Region
The Cape Floristic Region (CFR) includes a broad variety of bed rocks and soils are a mosaic of sandstone and shale substrates that give rise to a variety of soil types mainly sandstone, aeolian sands, shale, granite and limestone thereby creating heterogeneity in edaphic conditions. Species …

Phosphorus sensitivity in species of Proteaceae (Protea obtusifolia, Leucadendron coniferum and Leucadendron salignum) from different soil habitats : possible candidates for growth on former agricultural soils high in P
… Leucadedndron meridianum) soils in the Cape Floristic Region (CFR) were compared. These species were also investigated as potential candidates for growth on nutrient enriched, post-agricultural soils. In parallel, two crop plant species (Lupinus albus, with cluster roots; and L. …

The many forms of thirst : investigating forest constraints in the Cape Floristic Region
… the primary constraints of forests in the Cape Floristic Region (CFR), in South Africa. Based on a study by Lehmann et al. (2011) on savanna ecosystems, it was hypothesised that seasonal drought and moisture balance were more likely to limit forest distribution than broader rainfall …

The physiological importance of small leaf sizes in the mediterranean type ecosystem vegetation of the Cape floristic region
Numerous "Fynbos" species of the Cape Floristic Region (CFR) have particularly fine, narrow leaves. The rates of transpiration and heat loss are partially dependent on boundary layer conductance, which is determined by leaf shape and size, surface modifications and wind speed. We expected …

Germination success and drought response in Erica coccinea
… of resprouter and seeder Erica in the Cape Floristic Region (CFR) of South Africa is determined more by water availability. Erica seeders are predicted to withstand the mild droughts of the southwest CFR better than Erica resprouters, which would account for the abundance of seeders in …

The importance of hydrologic refugia for the diversity of the Cape Flora
… crucial for preserving species richness in the Cape Floristic Region (CFR) of South Africa, an area renowned for its exceptional plant species diversity and endemism, which is increasingly threatened by the impacts of global change. Despite the importance of refugia in the CFR, very little is …

Endemism and richness in the Cape floristic region: phytogeographic patterns and environmental correlates in a global biodiversity hotspot
… retrieved within the exceptionally species rich Cape Floristic Region (CFR), a global biodiversity hotspot in South Africa. Modern Analytical techniques, including a novel approach developed within this study, were used to identify Phytogeographical Centres. Moreover, the efficiency and …

Does pubescence increase uptake of nutrient deposition on leaves?
… with sparse leaf hair cover, such as in the Cape Proteaceae species of the Cape Floristic Region (CFR), remain unknown. 2. We postulated that leaf hairs of the Proteaceae in the CFR facilitate both nutrient absorption and water retention on the leaf surface. Leaf hair distribution is expected …

The thermal tolerances and preferences of native fishes in the Cape Floristic Region: towards understanding the effect of climate change on native fish species
… and reduction in rainfall in the Western Cape Province of South Africa is inevitable and unavoidable. Within the Western Cape lies the Cape Floristic Region (CFR); a biodiversity hotspot with high levels of endemism. This includes its freshwater fish assemblage. Whereas the current …

The preservation of the Cape flora : status, causes of rarity, ideals and priorities
The Cape Floristic Region (CFR), covering 90 000 km2, comprises one of the world's six floral kingdoms. With 8600 species, of which 68 per cent are endemic, it ranks amongst the richest of temperate and tropical floras. Although 19 per cent of the CFR occurs in nature reserves, by far the majority …
