| description | <p>The change in the structure of species communities along environmental gradients is a privileged field of ecology as it allows exploring a continuous progression of situations often in a small area, in this context, we are interested in studying the impact of altitude and slope on the density and the recovery rate of <em>Asphodelus microcarpus </em>population in mountainous ecosystem. <em>Asphodelus microcarpus </em>is an ecological model, which allows us to have an idea about the degree of degradation in mountainous ecosystem, the density increases with advanced degradation stage. Analysis of variance revealed a highly significant difference (P = 0.001) between the 20 selected stations. The principal component analysis revealed that the density is important in low altitudes around 750 m where the slopes are average, this correlation is the result of human pressures that weaken the mountain of Tessala.</p><p>International Journal of Environment Vol.5(3) 2016, pp.43-56</p> |
