Diversity of the genus Seira (Collembola: Entomobryidae: Seirinae) in the Fynbos and Southern Afrotemperate forest
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Soil is one of the most complex and understudied terrestrial habitats, and it comprises a wide
range of organisms that affect the functioning of terrestrial ecosystems. Despite the importance
of these ...
The regulation of Phosphoenolpyruvate (PEP) metabolism via Phosphoenolpyruvate Carboxylase (PEPC) in P-deficient roots and nodules of Virgilia divaricata
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Plants exhibit a flexible array of morphological, physiological and biochemical adaptations during
phosphorous limitation. Legumes are vulnerable to P deficiency, because it affects their ability to
fix ...
Fouling by non-indigenous marine species - impacts on biodiversity and mariculture
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Alien fouling species are most likely to be introduced into Saldanha Bay via two vectors: the high shipping volume experienced in the Bay and the intensive mariculture operations that take place in the ...
Does the application of vermicompost solid and liquid extracts influence the growth, N-nutrition and soil microbial diversity of the legume, Lupinus angustifolius?
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: Vermicomposts (VCs) are the solid excreta of earthworms, known to contain plant available nutrients, large amounts of microbial life and diversity, and plant growth regulating hormones. VCs may play an ...
Phosphorus mobilization and localisation in the roots and nodules of a Cape Floristic Region legume, and its impact on nitrogen fixation
(Stellenbosch : Stellenbosch University, 2015-12)
ENGLISH ABSTRACT: During phosphorus (P) deficiency, plants can exhibit a wide array of morphological,
physiological and biochemical responses. Legume plants are vulnerable to P deficiency,
because it affects their ability ...
Casuarina invasions : a multi-scale assessment of an important tree genus
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Understanding the processes that drive the invasion of non-native species is often essential for effective management. This thesis focuses on Casuarina spp. – an economically and ecologically important ...
Cytosystematics of Gerbils
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: The objectives of this research were to: (1) accurately identify chromosome homology, (2) identify chromosome rearrangements leading to diploid number variation and chromosome evolution to formulate the ...
Genetic population structure of penaeid prawns Penaeus monodon Fabricius 1798, Fenneropenaeus indicus H. Milne Edwards 1837 and Metapenaeus monoceros Fabricius 1798 in the Malindi–Ungwana Bay, Kenya
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: Comparative analyses of genetic diversity, population structure and evolutionary relationships
among co–distributed species can provide useful insights into fisheries management. In this
study, mitochondrial ...
Comparative phylogeography and phylogenetic relationships of the four-striped mouse genus, Rhabdomys, and the ectoparasitic sucking louse, Polyplax arvicanthis
(Stellenbosch : Stellenbosch University, 2013-03)
ENGLISH ABSTRACT: Within southern Africa, the widely distributed four-striped mouse Rhabdomys is parasitized by, amongst others, the host-specific ectoparasitic sucking louse, Polyplax arvicanthis. The present study ...
Spatial variation in plant nutrient composition on Marion Island
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: To estimate nutrient budgets and model nutrient cycling at a whole ecosystem level on sub-Antarctic Marion Island requires information on the spatial variability of plant nutrient concentrations on the ...
