In particular, we prove that there exists a global weak solution, if the order of the fractional diffusion α∈(1-c1, 2], where c1>0 is an explicit constant depending on the physical parameters present in the problem (chemosensitivity and strength of logistic damping). Furthermore, in the range 1-c2<α≤2 with 0
