Description The geographic mosaic theory of coevolution (GMTC) has provided new and novel insights to species interaction and coevolution meanwhile bridged the gap between population ecology to species evolution, thus has received a great attention. GMTC has been supported by numerous empirical studies meanwhile still suffer some challenges. For example, how does gene flow and geographic distance among metapopulations affect geographic mosaic effects? How to accurately determine and measure the 'hotspots' and 'coldspots'? In this study, we take the classic obligated mutualistic system fig-fig wasp as our research system, and totally 20 populations for each of the two species (monoecious Ficus altissima and dioecious F. tinctoria) that widely distributed in tropical and subtropical China will be investigated. We will measure both the selective traits and neutral traits for fig and fig wasps to quantify the differentiation of the traits among populations thus to determine the possible evolutionary 'hotspots' and 'cold spots'. Meanwhile, we will also determine how the population differentiation of fig volatile in receptive phase of the two species in responding to the hotspots and cold spots. Furthermore, the differences in gene flow and its influences to mosaic selection, the local reciprocal selection effect the sexual isolation of fig wasps will be investigated. As one of few examples that using the obligated mutualistic system examining the GMTC, this study will enrich our understanding of plant animal coevolution and meanwhile provide new and unequivocal verification to GMTC.
