Sexual size dimorphism in the evolutionary context of facultative paedomorphosis: insights from European newts.

abstract：BACKGROUND:The fern genus Dryopteris (Dryopteridaceae) is among the most common and species rich fern genera in temperate forests in the northern hemisphere containing 225-300 species worldwide. The circumscription of Dryopteris has been controversial and various related genera have, over the time, been included in and...
