| low support for separate species within the redpoll complex (carduelis flammea-hornemanni-cabaret) from analyses of mtdna and microsatellite markers. | the redpoll complex, consisting of three currently recognized species (carduelis flammea, c. hornemanni and c. cabaret), is polytypic in biometry, morphology, physiology and behaviour. however, previous genetic work has not revealed any indications of genetic differentiation. we analysed sequence variation in the mtdna control region, and allele frequencies of supposedly faster evolving microsatellites (n=10), in an attempt to detect molecular genetic support for the three species, as well as tw ... | 2008 | 18439841 |
| phylogeny and rapid northern and southern hemisphere speciation of goldfinches during the miocene and pliocene epochs. | mitochondrial cytochrome b (cyt b) from 25 out of 31 extant goldfinches, siskins, greenfinches and redpolls (genus carduelis) has been sequenced from living samples taken around the world, specimens have also been photographed. phylogenetic analysis consistently gave the same groups of birds, and this grouping was generally related to geographical proximity. it has been supposed that pleistocene glaciations played a crucial role in the origin of extant diversity and distribution of northern hemi ... | 1998 | 9791543 |
| comparative phylogeography of five avian species: implications for pleistocene evolutionary history in the qinghai-tibetan plateau. | pleistocene climate fluctuations have shaped the patterns of genetic diversity observed in extant species. in contrast to europe and north america where the effects of recent glacial cycles on genetic diversity have been well studied, the genetic legacy of the pleistocene for the qinghai-tibetan (tibetan) plateau, a region where glaciation was not synchronous with the north hemisphere ice sheet maxima, remains poorly understood. here, we compared the phylogeographical patterns of five avian spec ... | 2010 | 20002586 |
