Recent molecular phylogenetic studies of Commiphora (Burseraceae) have revealed a complex history of species evolution in this genus, which includes four separate invasions of Madagascar. Two of these invasions have resulted in radiations of species that are not well-characterized taxonomically due ...

This study evaluated the dynamics of bush cover in relation to the role played by seasonally grazed traditional enclosures compared to grazed rangelands. The result showed that herbaceous biomass was higher in enclosures than in the open grazed areas. Enclosures also showed more diversity and...

The vegetation and some associated environmental variables were investigated at Key Afer-Shala Luqa and Southwest of Lake Chamo, in the Gamo Gofa Zone, southern Ethiopia. To determine the species richness and classify the plant community types, analyse the species richness, evenness and diversity...

This paper focuses on the well-recognized herbal analgesics (opioids from opium (Papaver somniferum), salicin from Salix spp., tetrahydrocannabinols from cannabis (Cannabis sativa)), and plants under investigation for their possible analgesic effects (myrrh (Commiphora myrrha [Commiphora molmol]),...

Group meetings and individual farm visits were used to establish current tree planting practices in the smallholder farming sector of Zimbabwe. The number of tree species planted in each of the 8 districts studied ranged from 9 to 27, with 17 species occurring in at least half of the districts....

This paper provides an overview of some recent achievements in the area of production and utilization of fodder trees in East Africa. Most of the research work reviewed is part of the Agroforestry Research Network for Africa (AFRENA). In the sub-humid highlands the most common form of livestock...

The use of some medicinal plants their effects have been recorded from ancient writings to contemporary studies. The literature on 6 medicinal species (Punica granatum, Crocus sativa, Acorus calamus, Boswellia carteri [B. sacra], Commiphora myrrha [Commiphora molmol] and Cinnamomum cassia [...

In a pilot project in the Hiiraan region, 30 ha of sand were planted with Commiphora cuttings in cross-hatched lines in June 1983 and 18 species of trees and shrubs were planted between these lines. The Commiphora cuttings formed micro-windbreaks which reduced wind velocity and blowing sand, and...

A report in two parts, covering the sources, extraction and uses of, and markets for, natural oleoresins (excluding turpentine) and prepared oleoresins respectively. With the exception of galbanum (obtained from Ferula spp.), the natural oleoresins considered are all derived from trees or shrubs;...

Outlines the climate, geology, soils and vegetation of the Sahelian zone in Chad (i.e. the dry savanna to semi-desert belt immediately S. of the Sahara), and discusses the long-term deterioration in the soil and vegetation, confirmed by past records and largely attributable to man and livestock. An ...
