Influence of Holocene habitat availability on Pacific gray whale ( Eschrichtius robustus ) population dynamics as inferred from whole mitochondrial genome sequences and environmental niche modeling
Abstract Environmental changes since the Pleistocene and commercial whaling in the last few centuries have drastically reduced many whale populations, including gray whales in the North Pacific. Herein we use complete mitogenome sequences from 74 individuals to evaluate gray whale phylogeography and...
