Phylogenetic Lineages

In this paper, we review major classification schemes proposed for oaks by John Claudius Loudon, Anders Sandøe Ørsted, William Trelease, Otto Karl Anton Schwarz, Aimée Antoinette Camus, Yuri Leonárdovich Menitsky, and Kevin C. Nixon. Classifications of oaks (Fig. 1) have thus far been based entirely on morphological characters. They differed profoundly from each other because each taxonomist gave a different weight to distinguishing characters; often characters that are homoplastic in oaks. With the advent of molecular phylogenetics our view has considerably changed. One of the most profound changes has been the realisation that the traditional split between the East Asian subtropical to tropical subgenus Cyclobalanopsis and the subgenus Quercus that includes all other oaks is artificial. The traditional concept has been replaced by that of two major clades, each comprising three infrageneric groups: a Palearctic-Indomalayan clade including Group Ilex (Ilex oaks), Group Cerris (Cerris oaks) and Group Cyclobalanopsis (cycle-cup oaks), and a predominantly Nearctic clade including Group Protobalanus (intermediate or golden cup oaks), Group Lobatae (red oaks) and Group Quercus (white oaks, with most species in America and some 30 species in Eurasia). The main morphological feature characterising these phylogenetic lineages is pollen morphology, a character overlooked in traditional classifications. This realisation, along with the now available (molecular-)phylogenetic framework, opens new avenues for biogeographic, ecological and evolutionary studies and a re-appraisal of the fossil record. We provide an overview about recent advances in these fields and outline how the results of these studies contribute to the establishment of a unifying systematic scheme of oaks. Ultimately, we propose an updated classification of Quercus recognising two subgenera with eight sections. This classification considers morphological traits, molecular-phylogenetic relationships, and the evolutionary history of one of the most important temperate woody plant genera.

Coevolutionary History

The coevolutionary history of Lepidoptera and angiosperms is evaluated in relation to Croizat's panbiogeographic synthesis of angiosperm evolution. The panbiogeographic method of ocean basin classification is used to identify major patterns of trans-oceanic distribution for lepidopteran families and genera (principally non-ditrysian). The Pacific basin is identified as a major evolutionary centre for several 'primitive non-ditrysian Lepidoptera, including Zeugloptera, Aglossata, Heterobathmiina, Neopsuestina, Palaephatidae, Prodoxidae, and possibly the Dacnonypha. The ditrysian Ithomiidae are similarly classified with the Pacific while the related Daniidae are identified as Indian Ocean. An Indian Ocean baseline is proposed for the Callidulidae, Tinissimae and Perissomasticini (Tineidae). A 'coevolutionary' history is supported in terms of Lepidoptera and angiosperms sharing common biogeographic (spatiotemporal) characters associated with the pre-Cretaceous tectonic history of major ocean and sea basins. The lack of congruent higher level Lepidoptera-angiosperm phylogenies emerging from systematic studies may be due to a lack of cospeciation events, but this does not exclude a close ecological and evolutionary relationship through the history of both groups.
