Abstract

This Ph. D. dissertation is focused in Ziziphus lotus populations from the semiarid southeast of Iberian Peninsula (Almería and Murcia provinces). Z. lotus is a keystone species of a European priority habitat according to Habitat Directive, Habitat 5220*- Arborescent scrubs with Ziziphus lotus. Since 1950s, this habitat has suffered a severe degradation rate, which has continued in spite of its rating as priority habitat for conservation. The main aim of this research is assessing how the loss of habitat quality, at local and landscape scales, is affecting wild pollinator assemblages, genetic diversity and gene flow of Z. lotus populations in the semiarid southeast of Iberian Peninsula.
