Polyploid speciation in the Greater Cape Floristic Region : species limits within Ehrhara calycina
… species whose core distribution lies within the Greater Cape Floristic Region (GCFR). Importantly, it shows a high degree of morphological and ploidy level variation. Based on observations of distinct forms co-occurring at multiple sites, the hypothesis that E. calycina comprises more than one …

The role of geophytes in stone age hunter-gatherer subsistence and human evolution in the greater cape floristic region
… a large portion of the plant diversity in the Greater Cape Floristic Region (GCFR), where significant archaeological evidence of the evolution of human modernity has been identified in the Middle Stone Age (MSA). It is thought that the resources available in this region during this time period …

Distribution and phylogenetic inference within the flightless spring katydids (Tettigoniidae: Brinckiella Chopard, 1955) in the Greater Cape Floristic Region
… genus Brinckiella is an endemic group from the Greater Cape Floristic region (GCFR) with several undescribed species. Some of them are of conservation concern, categorized by IUCN as Endangered (EN) and Vulnerable (VU) due to their restricted distribution caused by livestock overgrazing, …

Phylogenetic relationships and the effects of edaphic heterogeneity on the distribution of Wiborgia (Fabaceae) in the Greater Cape Floristic region
The Greater Cape Floristic Region (GCFR) is divided into two subregions, the Core Cape Subregion (CCR) and Extra Cape Subregion (ECR), which are mainly characterized by Fynbos and Succulent Karoo biomes, and are recognized among global biodiversity hotspots. The soils in the ECR are mostly shale …

Taxonomy and evolutionary studies on the genus Psoralea L. (Psoraleeae, Fabaceae)
… endemic to southern Africa predominantly in the Greater Cape Floristic Region (GCFR). The genus Psoralea, consisting of 75 species endemic to southern Africa, is the second most speciose legume in the GCFR after Aspalathus (280 species). This thesis, consisting of a literature review, three …

Taxonomy and Life History of Gall Midges (Diptera, Cecidomyiidae) on Drosanthemum and Malephora (Aizoaceae) in South Africa
… and remarkably species-rich fauna and flora. The Greater Cape Floristic Region, consisting of the Cape Floristic Region and the Succulent Karoo Region, is home to South Africa's second most diverse plant family, the Aizoaceae. While the Aizoaceae are relatively well studied, there has been little …

Ecological resilience at semi-arid and temperate boundaries of the Mediterranean-type Fynbos Biome, South Africa, during the Holocene
… of the Mediterranean-type fynbos biome in the Greater Cape Floristic Region (GCFR) of South Africa, understanding of the longterm impacts of global change are particularly important. In this study, palaeoecological data are used to assess the effects of changes in climate, fire and land use on …

The natural history, sensory ecology and biogeography of the seed dispersal of large fruits in Fynbos
… all reseeding plants. In the Fynbos Biome of the Greater Cape Floristic Region (GCFR) of South Africa, at least 100 plant species have seed traits that suggest they are scatterhoarded by small mammals. The aims of this thesis were to investigate the dispersal biology of large-fruited Fynbos plants …

Reassessment of species limits and diversification process in the Cape grass genus Ehrharta Thunb
The Greater Cape Floristic Region (GCFR) of South Africa has one of the most biodiverse floras in the world. Although ecological speciation is thought to be a primary mechanism behind diversification in the GCFR, it has recently been hypothesised that non-ecological speciation may have an …

Systematics of the Relhaniinae (Asteraceae-Gnaphalieae) in southern Africa : geography and evolution in an endemic Cape plant lineage
The Greater Cape Floristic Region (GCFR) houses a flora unique for its diversity and high endemicity. A large amount of the diversity is housed in just a few lineages, presumed to have radiated in the region. For many of these lineages there is no robust phylogenetic hypothesis of relationships, …

Systematics and evolutionary ecology of Osteospermum section Polygalinae DC
… daisies, having most of its diversity in the Greater Cape Floristic Region of South Africa. The genus is characterised by remarkable variation in fruit structure and dispersal biology, putatively including species that employ myrmecochory (dispersal by ants). Myrmecochory is thought to be …

Behavioural, microhabitat, and phylogenetic dimensions of intrasexual contest competition in combatant monkey beetles (Scarabaeidae: Hopliini)
… diverse group of pollinating insects in the Greater Cape Floristic Region (GCFR) that shows a high degree of sexual dimorphism and mating behaviour driven by male-male competition. I build on previous observations of hind leg use in intrasexual male-male contest for reproductive access to …

Systematics of Hermannia L. (Malvaceae): a taxonomic review of the genus
… most species are distributed across Africa from Cape Verde eastwards to Saudi Arabia, with the majority restricted to Southern Africa. The taxonomy of the genus is not well understood, species concepts are poorly defined, and there have not been any comprehensive studies on its phylogeny, …

Molecular phylogenetics, taxonomy and niche-based conservation risk assessment of Thesium L. (Santalaceae)
… southern Africa, ca. 103 species occur in the Greater Cape Floristic Region (GCFR), of which about 72 are regional endemics. The GCFR Thesium, including ecologicalspecialists and generalists, offers an appropriate system for evaluating both the correlates of range extent, specialisation and the …
