Sentences with phrase «fox clade»

However, the fact that we detected only 13 — 14 base pair substitutions between the closest mainland gray fox lineage and the northern / southern island fox ancestor suggests that the date of divergence for the island fox clade could be more recent than 9200 years ago.

Our divergence date estimates for the island fox clade itself, ~ 9200 years ago, as Santarosae separated into four distinct islands and for the southern island fox lineage, ~ 7100 years ago, correspond well with the earliest AMS dated island fox bones (~ 7100 cal BP for northern and ~ 5640 cal BP for the southern islands).

Not exact matches

Our phylogenetic analysis (Fig. 3) revealed that fox haplotypes fell in two well - supported and divergent clades (Clades Aclades (Clades AClades A & B).

Glacial climatic fluctuations caused habitat changes, including the appearance of continental ice sheets as far south as Washington State [37], that may have caused range shifts in locally adapted gray fox populations, with foxes with clade B haplotypes existing as far south as southern California.

As the climate warmed during the Holocene, and suitable habitat expanded northward, gray fox population ranges shifted further north resulting in foxes with clade A haplotypes distributed as far north as Shasta County in northern California (Fig. 1).

Remarkably, island fox haplotypes formed a monophyletic clade nested within clade B, rather than with foxes from southern California, closest to the Channel Islands.
