Reconciling fossils and molecules: Cenozoic divergence of cichlid fishes and the biogeography of Madagascar

Aim The biogeographical origins of the extant vertebrates endemic to Madagascar are largely unsolved, but have often been related to vicariance in the context of fragmentation of the supercontinent Gondwana in the Mesozoic. Such hypotheses are especially appealing in the case of cichlid fishes, which show phylogenetic relationships reflecting the temporal successions of the breakup of Gondwana. We used molecular clock data to test this assumption. Location Fragments of the 16S rRNA gene and of the nuclear Tmo-4C4 locus, partly obtained from Genbank from South American, African, Malagasy and Indian cichlids were analysed. Methods Based on monophyletic cichlid radiations in African lakes, we …

Additional file 1 of Genetic relationships between sympatric and allopatric Coregonus ciscoes in North and Central Europe

Additional file 1: Table S1. Proportion of missing genotypes among the nine microsatellites (columns) in the 18 Coregonus populations (rows). Individuals with more than a single missing locus were omitted from subsequent statistical analyses. AS = autumn-spawner, SS = spring-Spawner. Table S2. Matrix of pairwise θ between sympatric populations of Lake Stechlin (Coregonus albula and C. fontanae), sampled in different years (below diagonal), and their lower 95% confidence intervals (above diagonal). Weak structure between (sub)populations is indicated by the lower CI including zero. Table S3. Matrix of pairwise θ between sympatric populations of Lake Breiter Luzin (Coregonus albula and C. luc…
