Cryptic variation fuels plant phenotypic change through hierarchical epistasis - Nature
Gene regulatory network architecture and complex dosage effects from paralogue diversification converge to shape phenotypic space, producing the potential for both strongly buffered phenotypes and sudden bursts of phenotypic change.

New Article: "The late rise of sky-island vegetation in the European Alps" rdcu.be/epLJg
A phylogenetic analysis of the flora of the Alps reveals that the flora is young and colonist rich. Its assembly was primarily driven by the Pleistocene climatic cycles.
