GENERAL INTRODUCTION The family Synodontidae is a group of fish characterized by lizard-like head, spineless fins and a small adipose fin and are almost circumtropical in distribution.
A small proportion of sporangia of P. palmivora, less than 1.0 per cent, formed by hyphae growing on cocoa pods germinated in humid air at 25°C whilst still attached to the hypha.to produce germ tubes terminated by secondary sporangia.
ABSTRACT The objectives of this study were to confirm for the first time, the identity of Trametes mushrooms from Northern Namibia and then to generate information on local uses and bioactive compounds of these Trametes species. To achieve this, samples were collected from Ohangwena, Omusati, Oshikoto and Oshana regions and identified as Trametes species based on morphological features. These were a basidiocarp with concentric zones, brown, tan or grey colour and pores from 2-3 pores/mm to po...
ABSTRACT The emergence of the Community-Based Natural Resources Management (CBNRM) approach in Namibia contributed to the establishment of communal conservancies that aim to conserve wildlife outside protected areas, as well as benefit local communities. Recent translocations in Namibia involved the movement of wildlife from protected areas to communal conservancies in order to expand the range of wildlife species in the areas they once occupied, as part of effective community-based conservat...
Abstract Biodiversity loss discussions are usually characterised by broad ranging views. Patterns of wildlife decline and attitudes towards conservation have received minimal attention in the north central communal areas of Namibia. Wildlife decline has been primarily attributed to life styles, climatic change and the disruption to conservation activities during the war for independence (1966 – 1989). This thesis examines attitudes towards wildlife and conservation, and patterns of biodiver...
ABSTRACT This study is concerned with the design and development of an annotation model that gives users the power of expressivity as required in Economic Intelligence (EI) context. Most of the existing annotation platforms lack this power of expressivity. The study also discovered a need to develop an annotation model for creating and structuring annotations that will adequately capture the intention of the users (EI actors) in decision making process. In addition, there was a need for a te...

ABSTRACT River-floodplains are highly productive environments capable of supporting large fisheries. In the Kavango and Caprivi Regions in Namibia, artisanal gillnet fisheries catch is dominated by three cichlids: Oreochromis andersonii, Oreochromis macrochir and Tilapia rendalli. Their abundance is declining because of increased fishing pressure and their stocks are becoming vulnerable to overfishing. The aim of this thesis was to provide management recommendations for the three cichlids by ...
ABSTRACT A central pathogenic feature in Plasmodium falciparum cerebral malaria (CM) is the sequestration of infected erythrocytes (IEs) which results in the obstruction of blood flow, inflammation and damage to the endothelial cell barrier integrity. Adhesion is mediated by a family of approximately 60 highly variant parasite proteins called P. falciparum erythrocyte membrane protein 1 (PfEMP1), which are displayed on the surface of infected cells. All PfEMP1 contain multiple extracellular ...
ABSTRACT Seven Aspergillus species, A. clavatus, A. flavus, A. Lutn i qe tus, A. niger, A. ochraceus, A. sulphureus and A. ustus have been used to investigate the role of three Coleopteran insect pests, namely, Cal.1osobrochus macula tus, st tophiJ. us zeamais and 'rribo tium castaneum in the persistance and spread of contaminant fungi among grains of maize (Zea mays) and rice (Oryza sativa) and seeds of bambara groundnut (Vigna subterranea) a nd cowpea (Vigna unguiculata). The Aspergi11us sp...
ABSTRACT The physiological and morphological characteristics of five strains of Sclerotium rolfsii, namely, XLL, XAl, XA2, ELI and EL2, which were identified as strains by the aversion test, were studied. The susceptibility of five varieties of cocoyam, 'Amankani fitaa', 'Arnankani fufuo', 'Arnankani kyirepe' and 'Amankani pa' of Xanthosoma sagittifolium and a single variety of Colocasia antiquo rum to these strains, was also investigated. The appearance of the strains on Potato Dextrose Aga...

ABSTRACT This study examines handicraft production and the effects of local and global spatio-temporal changes on craft production and craft-based livelihoods in the Ashanti region of Ghana. It also investigates the coping and survival mechanisms craftspeople have adopted to overcome production difficulties and poverty. The study is philosophically grounded in cultural geography (cultural globalisation). Using the Sustainable Livelihoods Framework, Value Chain analysis. Participatory Wealth ...
ABSTRACT Research was carried out to develop an effective inoculum carrier of the nodule bacterium, Rhizobium sp., for the inoculation of seeds of bambara groundnut [Vigna subterranea (L.) Verde , comb . nov. = Voandzeia subterranea (L. ) T h o u a r s ] f r o m a local material. Five out of 16 strains of Rhizobium sp. isolated from soils of legume farms at eight localities within a radius of 180km from L e g o n were used in experiments to test the efficiency of the carrier that was develope...
