Aspalathus and Podalyria legumes balance acquisition of phosphorus and nitrogen for growth in nutrient poor fynbos soils

Author: Maistry, Pravin Mark Date: 2015 Legume species nodulate and grow successfully in the Core Cape Subregion, a Mediterranean-climate ecosystem with fynbos vegetation found on infertile soils. The physiological mechanisms enabling tolerance of low availability of phosphorus (P) ... Read more
Conserving living landscapes: investigating the impacts of livestock grazing and assessing rangeland restoration potential in Overberg Renosterveld, South Africa

Author: Poulsen, Zoë Chapman Date: 2021 Biodiversity is declining faster than at any other time in the Earth's history, driven mostly by land use change and degradation. Overberg Renosterveld, some of the most species diverse mediterranean type shrublands, are no exception with ... Read more
Consistent phenological shifts in the making of a biodiversity hotspot: the Cape flora

Author: Warren, Ben ; Bakker, Freek ; Bellstedt, Dirk ; Bytebier, Benny ; ClaSZen-Bockhoff, Regine ; Dreyer, Leanne ; Edwards, Dawn ; Forest, Felix ; Galley, Chloe ; Hardy, Christopher ; Linder, H Peter ; Muasya, A Muthama ; Mummenhoff, Klaus ; Oberlander, Kenneth ; Quint Date: 2011 BACKGROUND: The best documented survival responses of organisms to past climate change on short (glacial-interglacial) timescales are distributional shifts. Despite ample evidence on such timescales for local adaptations of populations at ... Read more c b
Cyperaceae tribe Cyperae : phylogenetic relationships and evolutionary patterns of diagnostic characters

Author: Dludlu, Meshack N Date: 2007 Phylogenetic relationships in Cyperus and allied genera in the tribe Cypereae (family Cyperaceae) have been reconstructed using parsimony and Bayesian analyses of a combined data matrix, which consisted of plastid DNA (rbcL, trnL-F intergenic ... Read more
Ecological influences in the biogeography of the Austral sedges

Author: Viljoen, Jan-Adriaan Date: 2016 The biogeographic history of a species is a result of both stochastic processes such as dispersal and habitat filters that determine where a population with a given set of biological requirements can become established. In this dissertation, ... Read more
Phenotypic characterization of rhizobia isolates and distribution of Burkholderia rhizobia in the Core Cape Subregion

Author: Sinyanya, Kolisa Yola Date: 2016 The Core Cape Sub-region is well known for its low nutrient, low pH soils which harbour a variety of alpha and beta- Proteobacteria associated with a diversity of legume species. Soil bacteria are important for ecological processes and are ... Read more
Phylogenetic inference and macro-evolutionary patterns in Ficinia Schrad. (Cyperaceae)

Author: Francis, Caitlynne Melanie Date: 2009 The genus Ficinia Schrad. has its centre of diversity in the Cape Floristic Region and phylogenetic relationships within this genus have not been fully studied representing a gap in the body of work on the Cyperaceae. Phylogenetic analyses ... Read more
Phylogenetic relationships and the effects of edaphic heterogeneity on the distribution of Wiborgia (Fabaceae) in the Greater Cape Floristic region

Author: Moiloa, Ntwai Date: 2016 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 ... Read more
Phylogeny reconstruction of the Schoeneae (Cyperaceae) with a focus on southern African genera

Author: Henning, Jessica Date: 2008 In this study both plastid and nuclear DNA sequences (rbcL, trnL-trnF, rps16, ITS and ETS) were analysed. New sequences were added to the matrix from Verboom (2006). Parsimony method was used for phylogeny reconstruction. Morphological ... Read more
Plant growth, stress tolerant traits and regulation of heat activated proteins in Aspalathus linearis (Burm. f.) R. Dahlgren exposed to elevated temperature and drought

Author: MacAlister, Dunja Date: 2020 Climate change is increasingly becoming a concern on plant growth, as seen in the increased number of warmer days and nights as well as an increased occurrence of heat waves, and drought periods globally. The Intergovernmental Panel on Climate ... Read more
Radiation and Repeated Transoceanic Dispersal of Schoeneae (Cyperaceae) Through the Southern Hemisphere

Author: Viljoen, Jan-Adriaan ; Muasya, A Muthama ; Barrett, Russell ; Bruhl, Jeremy ; Gibbs, Adele ; Slingsby, Jasper ; Wilson, Karen ; Verboom, Anthony Date: 2013 • Premise of the study: The broad austral distribution of Schoeneae is almost certainly a product of long-distance dispersal. Owing to the inadequacies of existing phylogenetic data and a lack of rigorous biogeographic analysis, relationships ... Read more
Taxonomy and evolutionary studies on the genus Psoralea L. (Psoraleeae, Fabaceae)

Author: Bello, Abubakar Date: 2016 Psoraleeae is a tribe of the papilionoid legumes in Fabaceae comprising ca. 223 species in nine genera. Members of Psoraleeae are distributed worldwide, though they mainly occur in the temperate biomes. Of these, ca. 60% of the species (mostly ... Read more
Thermo and drought tolerance markers and regulation of heat stress proteins for chickpea (Cicer arietinum L.; Fabaceae) production in NE South Africa

Author: Makonya, Givemore Munashe Date: 2020 Chickpea (Cicer arietinum) is an important legume crop globally ranked third after dry bean (Phaseolus vulgaris) and field pea (Pisum sativum). It constitutes 20% of the total global pulse production and around 95% of its production and ... Read more
What environmental variables limit Typha expansion in Cape Flats wetlands?

Author: Kilian, Kay-Leigh Date: 2010 The explosive expansion of Typha capensis into the wetlands of the Cape Flats has resulted in decreased species diversity and habitat value. Several initiatives to control this expansion have had varied success and management of wetlands ... Read more
