"We believe that the rate of hybridization is a
direct consequence of dingo control. Like all wolf species, dingoes
are highly territorial and aggressive, and it is with great difficulty
that outsiders join stable packs [dingoes: 17; other wolves: 12,45].
Under natural conditions genetic lines are protected through kin
selection, and genetic variation within packs may be small due to
inbreeding and aggressive behavior towards outsiders [1,46]. This
can give rise to the development of genetic traits unique to each
pack, such as coat color [dingo: 11; wolf: 1). Dingo control may
increase the number of floaters which are more likely to breed with
dogs [47]. Similarly, hybridization between wolves and dogs has
been reported from Latvia where wolf-hunting was common [48].
We propose that the most efficient way to conserve the genetic
identity of dingoes and other wolves is to cease control."
