Don"t explode . seed pods open and seeds drop straight down ( low area )( on nguema,ed dispersal ) Chasmogamous seed pod , when touched , Can explode and send seeds flying up to. D dispersal ability low ability - low colonization. Stage 2- local adaptation and local extinction . ex.

Occurs only on two islands (again , not close by ) Disjunct distribution separate enough that the two populations are consideredseparate species .
