Cave-Dwelling Planariidae in Dinaric Karst Exhibit Differing Levels of Cave Trait Evolution. [PDF]

Ecol Evol
The Dinaric karst of Croatia is a global hotspot of subterranean biodiversity, yet its cave planarians remain poorly studied. By combining field sampling, phylogenetic analyses of mitochondrial COI and nuclear 18S markers, and analyses of pigmentation and eye reduction, we provide the first integrative assessment of cave planariids in Croatia and ...
