Resumen:
We compared mitochondrial cytochrome b sequences of ring-necked
pheasants (Phasianus colchicus) from Midwestern United States (SD and
NE, USA) to a molecular phylogeographic hypothesis of pheasants in the
native Eurasian range to understand which subspecies are represented by
wild and captive-released birds. We found that these birds represent 2
Eurasian lineages, which we refer to generally as northern Eurasian
(Colchicus group) and eastern China (Torquatus group). These
mitochondrial DNA lineages occur in different frequencies in the wild,
with the latter being 3 times more common. This suggests that 1) the
eastern China lineage is either better suited to surviving in natural
environments of the Midwestern United States outside captivity; 2) this
group was more highly represented in original or ongoing releases; or 3)
this group is more easily harvested. Confirmation of these possibilities
could affect the type of pheasants bred for release. We also detected a
low level of genetic variability in Midwestern birds relative to those
from the native range, suggestive of an inbreeding effect. (c) 2020 The
