AB Climate change can induce temporary, spatial or behavioral changes in species, so thatonly some species can adapt to the new climatic conditions. In the case of invasivespecies, it is expected that they will be promoted in a context of global change, giventheir high tolerance to environmental factors and phenotypic plasticity. Once in theinvaded range, these species can hybridize with native species thus introducing theirgenotype in the native biota. However, the effects that climate change will have onthis process of invasion by hybridization remain unclear. We evaluated the historicalestablishment of the reciprocal hybrids between the native Spartina maritima and theinvasive S. densiflora in the Gulf of Cadiz (SW Iberian Peninsula) and we related it toclimatic changes during the period 1955–2017. Our results showed that, accordingto their dating based on their rate of lateral expansion rates, the establishment ofS. maritima x densiflora and S. densiflora x maritima in the Gulf of Cadiz has occurredin the last two centuries and has been related to changes in air temperature andrainfall during the flowering periods of their parental species, with antagonist impacts onboth hybrids. Thus, the hybrid S. densiflora x maritima has been established in yearswith mild ends of spring and beginning of summer when the flowering of S. maritimalengthened and its pollen production was higher, and it coincided with the beginningof the flowering period of S. densiflora. Moreover, the establishment of this hybrid wasrelated to higher spring/summer rainfalls, probably due to the reduction in salinity inmiddle marshes. However, the hybrid S. maritima x densiflora, was established mainlyin warmer spring/summers in which the proportion of pollen:ovule of S. maritima wasreduced favoring its pollination by S. densiflora. As a consequence of the promotionof S. maritima x densiflora with climate change, the native and endangered speciesS. maritima would be threatened, as both taxa share the same habitat and the hybridshows a remarkably higher competitive potential.
