Abstract

|
| In order to promote and valorise phytogeographic concepts for conservation policy development, a simplified model based on the affiliation of Acanthaceae species sampled in the Democratic Republic of Congo with the phytogeographic sectors of Ndjele (1988) was tested. A data set of 3231 samples, 40 genus and 183 species was analysed. Spatial distribution maps were composed using a geographic information system. While certain species were observed throughout the territory, others were characteristic to one or several sectors. The Bemba sector and the Central Forest sector could be sources of taxon migration because of their large number of samples. The highest diversity of Acanthaceae was observed in the Bemba sector. « Indicator species », i.e. species only present in one single sector, have been identified except for the Congolo-Sudanian transition sector, the Lualaba sector and the Kivu Uplands sector. |
