Artkonzepte, in Bildern

Biodiversität, die Artenvielfalt, ist in aller Munde. Grundlage zum Messen der Biodiversität, ist fast immer (noch) die Anzahl der in einem Gebiet gefundenen Arten. Aber was ist eine Art? Ein paar Bildchen. Und Beispiele.

Monophyletic species

Probably the most common line one can read in phylogenetic papers scratching at the surface of evolution is "species xxx is not monophyletic" or "supports species yyy as monophyletic".
