A common challenge in phylogenetic reconstruction is to find enough
suitable genomic markers to reliably trace splitting events with short
internodes. Here we present phylogenetic analyses based on genome-wide
single-nucleotide polymorphisms (SNPs) of an enigmatic avian radiation,
the subspecies complex of Afrocanarian blue tits (Cyanistes teneriffae).
The two sister species, the Eurasian blue tit (Cyanistes caeruleus) and
the azure tit (Cyanistes cyanus), constituted the outgroup. We generated a
large data set of SNPs for analysis of population structure and phylogeny.
We also adapted our protocol to utilize degraded DNA from old museum skins
from Libya. We found strong population structuring that largely confirmed
subspecies monophyly, and constructed a coalescent-based phylogeny with
full support at all major nodes. The results are consistent with a recent
hypothesis that La Palma and Libya are relic populations of an ancient
Afrocanarian blue tit, although a small data set for Libya could not
resolve its position relative to La Palma. The birds on the eastern
islands of Fuerteventura and Lanzarote are similar to those in Morocco.
Together they constitute the sister group to the clade containing the
other Canary Islands (except La Palma), in which El Hierro is sister to
the three central islands. Hence, extant Canary Islands populations seem
to originate from multiple independent colonisation events. We also found
population divergences in a key reproductive trait, viz. sperm length,
which may constitute reproductive barriers between certain populations. We
recommend a taxonomic revision of this polytypic species, where several
subspecies should qualify for species rank.
