Ecological Phytogeography: A Case Study of Commiphora Species
Journal Title: STAR Journal - Year 2013, Vol 2, Issue 3
Abstract
The present paper stipulated phytogeography, ecological ranges, possible origin and migratory route of Commiphora Jacq. species. Data were gathered from the field, herbarium and secondary sources. Information on distribution, altitude and soil preferences were compiled and aggregated together. Phytogeographical aspect of the group has been analyzed using Brooks’s parsimony analysis (1990) which was done by tabulating flora regions versus the species under consideration where the matrix has been filled as either presence or absence. The result of data on phytogeography showed three patterns of distribution. Based on the plate tectonic theory, evolution and diversification of most angiosperm families into consideration, the origin of Commiphora has been discussed in details. It was recommended that the migratory route of Commiphora still requires further investigation and needs to be corroborated with data on the age of the genus and that of the concept of plate tectonic theory.
