Invasive species present a major threat to global biodiversity.
Understanding genetic patterns and evolutionary processes that reinforce
successful establishment is paramount for elucidating mechanisms
underlying biological invasions. Among birds, the ring-necked parakeet
(Psittacula krameri) is one of the most successful invasive species,
established in over 35 countries. However, little is known about the
evolutionary genetic origins of this species and what population genetic
signatures tell us about patterns of invasion. We reveal the ancestral
origins of populations across the invasive range and explore the potential
influence of climate and propagule pressure from the pet trade on observed
genetic patterns. Ring-necked parakeet samples representing the ancestral
native range (n = 96) were collected from museum specimens, and modern
samples from the invasive range (n = 855) were gathered from across
Europe, Mauritius and Seychelles, and sequenced for two mitochondrial DNA
markers comprising 868 bp of cytochrome b and control region, and
genotyped at 10 microsatellite loci. Invasive populations comprise birds
that originate predominantly from Pakistan and northern areas of India.
Haplotypes associated with more northerly distribution limits in the
ancestral native range were more prevalent in invasive populations in
Europe, and the predominance of Asian haplotypes in Europe is consistent
with the higher number of Asian birds transported by the pet trade outside
the native range. Successful establishment of invasive species is likely
to be underpinned by a combination of environmental and anthropogenic
influences.
