Figure 1From: Stability analysis of a fractional-order two-species facultative mutualism model with harvesting (1a) The relationship between the numbers of individuals of species \(\pmb{x_{1}}\) , \(\pmb{x_{2}}\) with respect to time t . (1b) The relationship between the values of \(\pmb{x_{1}}\) and \(\pmb{x_{2}}\) with \(\pmb{\alpha=0.5}\) for \(\pmb{(x_{1}(0),x_{2}(0))=(70,110), (90,90), \text{ and } (110,70)}\) .
