CASE STUDY 7.2 Phylogeography of Red Deers in Eurasia
Reddeershavebeenassignedtotwodifferentspecies, Cervus elaphus inEurasia
and C. canadensis in North America. The recognition of subspecies within them
is questioned, as is the assignment of some Central Asian subspecies to both
species. The present classification is based on morphological characters, such as
body and antler size, antler shape, and cranial measurements. Ludt et al. (2004)
undertook a phylogeographic analysis in order to investigate whether red deers
represent one or two different species and whether the named subspecies are
consistent with knowledge based on molecular data.
Ludt et al. (2004) analyzed samples of tissue from fifty localities, which rep-
resent most living species and subspecies of Cervus elaphus and C. canadensis
across most of their range, as well as Sika deer ( C. nippon ), Thorold's white lipped
deer ( C. albirostris ), sambars ( C. unicolor and C. timorensis ), and hog deer ( Ax-
is porcinus ). Sequences of Dama dama, Bos taurus, and Moschus moschifer-
us were used as outgroups. Sequences were aligned with ClustalX version 1.83
(Thompson et al. 1997) and checked visually. Initial sequence comparisons and
measures of variability were performed with Mega version 2.1 (Kumar et al. 2001).
