Chapter 3 Evaluation of Several Tree Species for Activity Against the Animal Fungal Pathogen Aspergillus Fumigatus
Chapter 3 Evaluation of several tree species for activity against the animal fungal pathogen Aspergillus fumigatus M.M. Suleiman, L.J. McGaw, V. Naidoo, J.N. Eloff PREFACE The plant species that were selected in the previous chapter had to be evaluated to determine which species should be used for in depth investigation. The minimum inhibitory concentration (MIC) of the extract was determined to confirmed earlier investigation. We evaluate the effects of the extract further on other important animal fungal pathogens. The text in this chapter was submitted and accepted as manuscript for publication to South African Journal of Botany, Vol. 76, pages 64-71 to enable wider readership of the results obtained. Abstract Aspergillus fumigatus causes severe problems in poultry production systems. Seven South African tree species were selected from the database of the Phytomedicine Programme based on its antifungal activity against the fungus Cryptococcus neoformans. The acetone leaf extracts of the plants had minimum inhibitory concentrations (MICs) of 0.1 mg/ml and lower in the preliminary screening. The antibacterial and antifungal activities of hexane, dichloromethane, acetone and methanol extracts of the leaves were determined using a two-fold serial microdilution method against a range of commonly encountered animal pathogenic fungi (Aspergillus fumigatus, Candida albicans, Cryptococcus neoformans, Microsporum canis and Sporothrix schenckii) and four nosocomial bacteria (Staphylococcus aureus, Enterococcus faecalis, Escherichia coli and Pseudomonas aeruginosa). The plant species investigated were Combretum vendae (A.E. van Wyk) (Combretaceae), Commiphora harveyi (Engl.) Engl. (Burseraceae), Khaya anthotheca (Welm.) C.DC (Meliaceae), Kirkia wilmsii Engl. (Kirkiaceae), Loxostylis alata A. Spreng. ex Rchb. -
Exploring the Benefits and Challenges of Indigenous Foods in an African Context Using a Case Study of Community Gardens in the Western Cape of South Africa
Exploring the benefits and challenges of indigenous foods in an African context using a case study of community gardens in the Western Cape of South Africa by Francia-Marié de Bruin Thesis presented in partial fulfilment of the requirements for the degree Of Master of Philosophy in Sustainable Development in the Faculty of Economic and Management Sciences at Stellenbosch University Supervisor: Dr Laura Pereira Co-Supervisor: Catherine (Loubie) Rusch March 2018 Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third-party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Date: March 2018 Copyright © 2018 Stellenbosch University All rights reserved i | P a g e Stellenbosch University https://scholar.sun.ac.za Abstract Research suggests that the benefits and value of indigenous foods within the South African context have not been fully utilised. Their potential value to the South African food system and food security which is embedded within it, could be enhanced were their benefits to be explored more comprehensively. Therefore, the aim of this research was to systematically review literature using relevant search criteria and databases relating to underutilised indigenous crop species and foods in Africa as well as abroad (including the Oceania, South America and Asia). The intention was to provide an encompassing overview of both literature and literature gaps regarding nutritional, environmental, economic, and social-cultural benefits and challenges of indigenous food plants. -

E-mail: Abstract: The Rondônia Natural Resources Management Project (PLANAFLORO) was a strategic program developed in partnership between the Brazilian Government and The World Bank in 1992, with the purpose of stimulating the sustainable development and protection of the Amazon in the state of Rondônia. More than a decade after the PLANAFORO program concluded, the aim of the present work is to recover and share the information from the long-abandoned plant collections made during the project’s ecological-economic zoning phase. Most of the material analyzed was sterile, but the fertile voucher specimens recovered are listed here. The material examined represents 378 species in 234 genera and 76 families of angiosperms. Some 8 genera, 68 species, 3 subspecies and 1 variety are new records for Rondônia State. It is our intention that this information will stimulate future studies and contribute to a better understanding and more effective conservation of the plant diversity in the southwestern Amazon of Brazil. Introduction The PLANAFLORO Project funded botanical expeditions In early 1990, Brazilian Amazon was facing remarkably in different areas of the state to inventory arboreal plants high rates of forest conversion (Laurance et al. -

The Monophyly of Bursera and Its Impact for Divergence Times of Burseraceae
TAXON 61 (2) • April 2012: 333–343 Becerra & al. • Monophyly of Bursera The monophyly of Bursera and its impact for divergence times of Burseraceae Judith X. Becerra,1 Kogi Noge,2 Sarai Olivier1 & D. Lawrence Venable3 1 Department of Biosphere 2, University of Arizona, Tucson, Arizona 85721, U.S.A. 2 Department of Biological Production, Akita Prefectural University, Akita 010-0195, Japan 3 Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, Arizona 85721, U.S.A. Author for correspondence: Judith X. Becerra, [email protected] Abstract Bursera is one of the most diverse and abundant groups of trees and shrubs of the Mexican tropical dry forests. Its interaction with its specialist herbivores in the chrysomelid genus Blepharida, is one of the best-studied coevolutionary systems. Prior studies based on molecular phylogenies concluded that Bursera is a monophyletic genus. Recently, however, other molecular analyses have suggested that the genus might be paraphyletic, with the closely related Commiphora, nested within Bursera. If this is correct, then interpretations of coevolution results would have to be revised. Whether Bursera is or is not monophyletic also has implications for the age of Burseraceae, since previous dates were based on calibrations using Bursera fossils assuming that Bursera was paraphyletic. We performed a phylogenetic analysis of 76 species and varieties of Bursera, 51 species of Commiphora, and 13 outgroups using nuclear DNA data. We also reconstructed a phylogeny of the Burseraceae using 59 members of the family, 9 outgroups and nuclear and chloroplast sequence data. These analyses strongly confirm previous conclusions that this genus is monophyletic. -
