Educators' experiences of an appraisal system in an independent school in KwaZulu-Natal.

Thesis (M.Ed.) - University of KwaZulu-Natal, 2005.This mini-dissertation reports on a case study of teachers' perceptions of the performance appraisal system used at an independent school in the greater Durban area in Kwa-Zulu Natal. As the system was implemented at a time when appraisal was only mandatory in government schools and not i

Systematics, diversity and forage value of indigenous legumes of South Africa, Lesotho and Swaziland

The diversity of legumes, indigenous to South Africa, Lesotho and Swaziland is reported using recorded descriptive and distribution data. A total of 24 tribes, 118 genera and 1662 species were documented with the majority of genera belonging to subfamily Faboideae, tribe Phaseoleae, and the majority of species to tribe Crotalarieae. In terms of distribution patterns, most species were present in the Savanna Biome and Central Bushveld Bioregion. Even though most tribes contain species with secondary metabolites (mainly non-protein amino acids), tribes containing poisonous species are far fewer. Herbs are the key growth form, followed by shrubs, dwarf shrubs and trees. The majority of species are perennials. A map representing the collection intensity for the study area showed that the majority of legumes species were collected in the Fynbos, Savanna and Grassland Biome. It is concluded that indigenous South African legumes are extremely diverse and this denotes the importance of further investigating their forage potential or use in other agricultural practices.Key words: Biomes, bioregions, Fabaceae, fodder, genebank, Leguminosae, pastures, tribe

Integrating biotechnology into the polyfarm concept

The polyfarm concept aims at strengthening traditional and appropriate farming technologies within the local agro-economic, cultural and socio-economic constraints of rural small farming. Different modules can be grouped together to suit the needs of the farmer. The polyfarm can serve as a demonstration and training facility to make rural farmers aware of the existence of biotechnologically-enhanced crops, their benefits and potential for use by resource-poor farmers. Enhanced soybean and maize are planted together with the conventional crop to demonstrate that these crops can improve yields, cut costs, reduce spraying and save time for the small-scale farmers

The benefits of an extra-curricular 'reading for enjoyment' programme for primary school learners

Changing perceptions of literacy over the past few decades have produced new approaches to the problem of how best to improve the literacy competence of primary school learners. Literacy remains a continuous problem in South Africa, as learners lack motivation to read or are struggling to read, write, and learn in a language that is unfamiliar to them. Researchers such as Street (2005) believe that literacy should not be viewed only as a set of skills to be mastered, but rather as something which must be understood in its broader social context. In accordance with this theory, the South African organisation PRAESA uses their Nal'ibali campaign to promote 'reading for enjoyment' and the formation of 'reading clubs' in order to improve learners' motivation to read and thus their literacy competence by increasing their exposure to pleasurable reading experiences. In this study it is argued that reading for enjoyment is beneficial to primary school learners' literacy competence as well as their personal and social development. In this study, Grade 5, 6, and 7 learners belonging to the reading club at a primary school in Port Elizabeth were observed over a six-month period. Data was collected through ethnographic observation of the reading club sessions and compiled into a detailed expository and sequential report. This narrative was then analysed in order to determine to what extent the learners had benefited in terms of their development from their participation in the reading club's activities. The analysis of the narrative demonstrated that learners' literacy competence, as well as personal and social skills such as self-confidence and tolerance, had been enhanced by the learners' voluntary participation in enjoyment-centred experiences with literacy. The findings of this study demonstrate that, in under-resourced schools and communities lacking a strong reading culture, an extra-curricular 'reading club' with a focus on reading for enjoyment was able to improve learners' literacy skills and provide opportunities for holistic growth by increasing learners' motivation to read

Collection Priorities of Pasture Genetic Resources in the Paniceae Native to South Africa

There is an urgent need for the prioritization and ex situ conservation of pasture grass species. Many pasture grasses are still in the process of domestication and grasslands in the tropical, subtropical, semi-arid and arid regions of the world are therefore a major source of genetic material for future forage improvement. Within South Africa, it was found that the Paniceae contains several species with high pasture value and that many populations of these species are found in water-limited environments. Therefore, it was proposed that a strategy be developed for the South African National Forage Genebank to prioritize efforts to collect and conserve seed of grass species within the Paniceae, focussing especially on those species in genera Anthephora, Brachiaria, Digitaria, Panicum and Setaria located in areas receiving less than 600 mm of annual precipitation

Biogeographical patterns of grasses (Poaceae) indigenous to South Africa, Lesotho and Eswatini

The ecological and economical importance of African grasses in sustaining animal production prompted studies to quantify the wealth of grass genetic resources indigenous to southern Africa. Plant collection and occurrence data were extracted from two southern African datasets, BODATSA and PHYTOBAS, and analysed to establish biogeographical patterns in the grass flora indigenous to South Africa, Lesotho and Eswatini. A total of 1 648 quarter degree grid cells, representing 674 grass species, were used in an agglomerative hierarchical clustering to determine biogeographical units being referred to as grasschoria. Six distinct groups formed, mainly following existing biome vegetation units, termed the Grassland, Indian Ocean Coastal Belt, Fynbos, Savanna, Central Arid Region and Succulent Karoo grasschoria. The description focuses on associated phytochoria, floristic links, key species, climate and soil properties. The main gradient distinguishing grasschoria was a rainfall-temperature gradient. The collection, conservation and breeding of pasture grass species adapted to especially arid and semi-arid environments, could be managed more efficiently by using these results, but also calling on the need to describe and label infraspecific genetic variants, including ecotypes.http://www.tandfonline.com/toc/tarf20/currentpm2021Plant Production and Soil Scienc

A phytogeographical classification and survey of the indigenous browse flora of South Africa, Lesotho, and Eswatini

DATA AVAILABILITY STATEMENT : All data presented in this manuscript are available from the corresponding author upon reasonable request.SUPPLEMENTARY MATERIALS : FIGURE S1: Clusters formed by AHC assigned to a generalist group and seven browse-choria with clear geographical boundaries; FIGURE S2: Distribution patterns of key, annual, endangered, and invasive browse of South Africa, Eswatini, and Lesotho; TABLE S1. A list of declared woody encroacher species, indigenous to South Africa, Eswatini, and Lesotho, browsed by livestock and game.Rangelands in South Africa, Lesotho, and Eswatini contain a rich diversity of valuable fodder trees and shrubs. This research is the first attempt to document the regional diversity and distribution of these browse resources. Scientific publications, textbooks, databases, and published reports were accessed to compile a database of plant species that were recorded as utilised by ruminants and non-ruminants. Relevant forage attributes, such as functional traits as well as utilisation traits, were added to each species record. Thereafter, distribution records were extracted from the South African National Biodiversity Institute’s Botanical Database of South Africa and analysed with numerical techniques to establish phytogeographical patterns. A total of 613 plant species from 76 families have been recorded, which formed seven distinct phytochoria, termed the Central Arid, Eastern Subtropical, Highland Temperate, Moist Temperate, Northern Subtropical, Southern Temperate, andWestern Arid browse-choria. Key families and species, as well as functional and utilisation traits, are discussed, focusing on key species present in the browse-choria. This browse database, together with the earlier compiled Leguminosae and Poaceae databases, will be used to prioritise indigenous southern African plant species/infraspecific taxa to be collected for the conservation of genetic resources and future evaluations for potential development as forage crops.The Red Meat Research and Development (RMRD) fund of South Africa.https://www.mdpi.com/journal/diversityam2024Plant Production and Soil ScienceSDG-15:Life on lan

Diversity and biogeographical patterns of legumes (Leguminosae) indigenous to southern Africa

The principal aim of this study was to establish biogeographical patterns in the legume flora of southern Africa so as to facilitate the selection of species with agricultural potential. Plant collection data from the National Herbarium, South Africa, were analysed to establish the diversity and areas covered by legumes (Leguminosae/Fabaceae) indigenous to South Africa, Lesotho and Swaziland. A total of 27,322 records from 1,619 quarter degree grid cells, representing 1,580 species, 122 genera and 24 tribes were included in the analyses. Agglomerative hierarchical clustering was applied to the presence or absence of legume species in quarter degree grid cells, the resultant natural biogeographical regions (choria) being referred to as leguminochoria. The description of the 16 uniquely formed leguminochoria focuses on defining the associated bioregions and biomes, as well as on the key climate and soil properties. Legume species with a high occurrence in a leguminochorion are listed as key species. The dominant growth form of key species, species richness and range within each leguminochorion is discussed. Floristic links between the leguminochoria are established, by examining and comparing key species common to clusters, using a vegetation classification program. Soil pH and mean annual minimum temperature were found to be the main drivers for distinguishing among legume assemblages. This is the first time that distribution data for legumes has been used to identify biogeographical areas covered by leguminochoria on the subcontinent. One potential application of the results of this study is to assist in the selection of legumes for pasture breeding and soil conservation programs, especially in arid and semi-arid environments.This paper is dedicated to the memory of Robert Howard (Bobby) Westfall (17 December 1944–21 January 2016), vegetation ecologist and friend whose sudden death during the preparation of this manuscript deprived us of an invaluable collaborator.Financial assistance from the University of Pretoria is acknowledged with thanks.http://phytokeys.pensoft.nethttp://opendatacommons.org/licenses/odbl/1.0/am2016Plant Scienc
