The aim of this research is to determine the diversity of Acanthaceae species in Ivory Coast, as well as the effect of climate change on their distribution. Variations in climatic variables including precipitation and temperature are likely to have an effect on biodiversity and the spatial distribution of species-friendly ecosystems. The habitats of Dicliptera alternans Lindau, Elytraria ivorensis Dokosi, and Whitfieldia lateritia Hook. were modelled using the concept of «Maximum Entropy» under current and future climatic conditions (horizon 2050/scénario A2). These species were chosen based on the number of occurrences on the one hand, and the endangered existence of the species on the other. The species' contact information was gathered and combined with bioclimatic data from the www.worldbioclim.org database. For each species, the surface of the theoretically desirable zones of distribution (or not) was determined. The record retrieval revealed a total of 106 species, classified into 39 groups, with 16 percent of them being endemic to the Ivory Coast. On the local list of endangered and rare species of the Ivory Coast of Aké-Assi L., 7 species are listed. The results show that the environmental variable «Seasonal variation of temperature (Bio 4) » is the environmental variable that contributed the most to the prediction of the model of the species Dicliptera alternans Lindau, Elytraria ivorensis Dokosi, and Whitfieldia lateritia by 2050. The A2 scenario predicts that by 2050, the surface area of the species' potentially favourable zones will be decreased by 67.66 percent, 3.35 percent, and 1.17 percent, respectively, for Dicliptera alternans Lindau, Elytraria ivorensis Dokosi, and Whitfieldia lateritia Hook. Despite these changes, the findings indicate that protected areas in Ivory Coast remain refuges for species of the Acanthaceae family under current and potential environmental conditions. This research backs up the effect of climate change on the spatiotemporal distribution of organisms. This study would assist in better directing conservation and management decisions for protected areas as biodiversity refuges.
