Pleistocene glacial periods have had a major influence on the genetic variation and differentiation of plant populations in tropical mountains. However, the effect of these cycles on morphological differentiation remains virtually unexplored.

Climatic niche and population genetic structure of mistletoes
The prevalent view about genetic structuring in parasitic plants is that host-race formation is due to varying degrees of host specificity. However, the relative importance of ecological niche divergence and host specificity remains poorly understood.
