| 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 |
| local differentiation in the presence of gene flow in the citril finch serinus citrinella. | it is well known theoretically that gene flow can impede genetic differentiation between populations. in this study, we show that in a highly mobile bird species, where dispersal is well documented, there is a strong genetic and morphological differentiation over a very short geographical scale (less than 5 km). allocation tests revealed that birds caught in one area were assigned genetically to the same area with a very high probability, in spite of current gene flow. populations were also morp ... | 2006 | 17148333 |
