Abstract [en]

Phylogenetic relationships among major groups of passeriform birds were studied by analyses of nucleotide sequence data from two nuclear genes, c-myc and RAG-1. The results corroborated both the monophyly of the order Passeriformes, and the major dichotomy into oscine and suboscine passerines previously suggested based on syringeal morphology and DNA-DNA hybridizations. The representatives of the Old World suboscines (families Eurylaimidae, Philepittidae and Pittidae) formed a monophyletic clade. The New World suboscines clustered into two clades. The first contained Conopophaga (Conopophagidae), Furnarius (Furnariidae), Lepidocolaptes (Dendrocolaptidae), Thamnophilus (Formicariidae), and Rhinocrypta (Rhinocryptidae). Previously, the monophyly of this group has been inferred from their possession of a unique, "tracheophone" syrinx, and from DNA-DNA hybridisation data. The second clade of New World suboscines includes Gubernetes and Muscivora (Tyrannidae), Phytotoma (Phytotomidae), Tityra (Cotingidae) and Pipra (Pipridae). This group of families have been considered monophyletic based on morphology (although ambiguously) and DNA-DNA hybridisation. The sister group relationship of Tityra and Phytotoma supports the previously supposed cotingid affinity of Phytotoma. Nuclear DNA data also unambiguously group the lyrebirds Menura with the oscines.

The presented results from the analysis of nuclear DNA agree well with morphology and DNA-DNA hybridisation data. The precise age of the divergences studied herein are unknown but based on interpretations of the fossil record of passerine birds many of them might date back to the early Tertiary. The agreement between data from the nuclear DNA and other sources, along with the fact that neither of the studied genes showed sign of saturation, indicate the great potential of these two nuclear genes to resolve very old divergences in birds.

Abstract [en]

This thesis concerns the phylogenetic relationships among suboscine birds with special emphasis on the antbird-ovenbird complex (Aves: Furnariida). The principal aim is to produce a framework for future systematic and comparative studies of suboscines by generating robust phylogenetic hypotheses from DNA-sequence data. Several gene regions, mostly from the nuclear genome, are used in order to get genetically independent estimates of phylogenetic relationships. The study is pioneering in the extensive use of nuclear DNA sequences to resolve passerine relationships.

The phylogenetic hypotheses are overall well supported by high nodal support values, and there is an overall good phylogenetic agreement between the different gene regions used. Several existing hypotheses about deeper relationships among New World suboscines based on morphology and DNA-DNA hybridisations are corroborated. In addition, novel hypotheses of relationships within the antbird-ovenbird complex are generated, e.g., a non-monophyletic origin of the ground antbirds, a basal position of the genus Sclerurus in relation to woodcreepers and core-ovenbirds, and a basal position of the genera Terenura, Myrmornis, Pygiptila and Thamnistes in relation to other typical antbirds.

Based on the results the current knowledge of systematic relationships among suboscines in general, and within the antbird-ovenbird complex in particular, are summarised and discussed. The thesis also includes discussions of recent methodological developments in avian molecular systematics, the use of morphological characters in phylogenetic reconstruction, and the problem of phylogenetic incongruence between data sets.
