Previous studies demonstrated that the invasion of land affected plastids and mitochondria differently and that the paths of mitochondrial integration differed between animals and plants. Ot...

Members of the plant genus Selaginella (de Beauvois 1805) have few known insect herbivores even though they are considered by some to be 'living fossils', with extant taxa virtually indistinguishable from 300 Mya fossils. Butterflies are well-known herbivores, and the satyrs are among the most speciose of them despite having radiated ∼ 35 Mya ago. Nearly all satyrs feed on grass or sedges, but ...
