Keywords	Tsuga / altitudinal hybrid zones / genetic swamping / adaptive introgression
Outline of Research at the Start	Using genetic data we will examine hybridisation dynamics between Japan's two endemic Tsuga species at the southern range-edge of subalpine T. diversifolia in Shikoku, where the temperate T. sieboldii co-occurs, providing crucial insight into the risk hybridisation may pose under a warming climate.
