The Dawson caribou (Rangifer tarandus dawsoni) was a rare subspecies of caribou that inhabited Haida Gwaii, an archipelago located 80 km off the west coast of Canada. It became extinct during the early part of the 20th century and to this day all that remains of Dawson caribou are several pelts, skulls, and antlers. With the exception of a physical description based on these remains, not much is known about the taxonomy of this subspecies of caribou. Using molecular and ancient-DNA techniques…

Evidence of Recent Population Differentiation in Orange-crowned Warblers (Vermivora celata) in Haida Gwaii
- Environmental Science, Biology
- 2010
Patterns of genetic diversity in western Orange-crowned Warbler populations do not provide evidence that the species persisted in a Pleistocene refugium in the area of Haida Gwaii, and modest genetic differentiation among populations is found.

Genetic evidence for the persistence of the critically endangered Sierra Nevada red fox in California
- Environmental ScienceConservation Genetics
- 2006
Findings provide strong evidence that the native Sierra Nevada red fox has persisted in northern California, as all nine samples from this population had the same haplotype, suggesting that several historic haplotypes may have become lost.
Postglacial population genetic differentiation potentially facilitated by a flexible migratory strategy in Golden-crowned Kinglets (Regulussatrapa)
- Environmental Science, Biology

Evidence supports the hypothesis that some taxa persisted in unglaciated refugia during the Last Glacial Maximum, such as on Haida Gwaii, and reports significant gene flow between the western North American mainland from mitochondrial markers, but significant population genetic differentiation at nuclear markers.
Available names for Rangifer (Mammalia, Artiodactyla, Cervidae) species and subspecies
- BiologyZooKeys
- 2022
This paper reviews available names for recently defined ecotypes of reindeer and caribou in compliance with ICZN rules for zoological nomenclature and shows that many of the subspecies and several species synonymised out of existence are, in fact, valid.
On the land mammals of the Queen Charlotte Islands, British Columbia, by John Henry Keen, with a catalogue of specimens
- Environmental Science
- 2017
The Reverend John Henry Keen collected plants and animals in the vicinity of the Anglican mission at Massett, on the north-central coast of the Queen Charlotte Islands, British Columbia, Canada, resulting in the first detailed information on the natural history of that region, particularly of the beetle fauna.

The results support the need for actions by wildlife managers to curtail deer impacts as soon as these become evident, especially in reserves and protected areas that lack hunters and other deer predators.

Origins of endemic stickleback from the Queen Charlotte Islands: mitochondrial and morphological evidence
- Biology
- 1996
A sample of 33 stickleback from the mid-Pacific was obtained and found both mitochondrial DNA (mtDNA) lineages, strongly suggesting ongoing dispersal of these fish across the Pacific, and inconsistent with previous suggestions of relict status for one of the lineages.

It is found that the Haida Gwaii bear are indistinguishable from coastal bear of British Columbia and Vancouver Island, but are highly distinct from continental bear, consistent with recent suggestions that a glacial refugium existed on the now submerged continental shelf.

A broad molecular survey of some of Haida Gwaii's putative glacial relicts to determine whether mtDNA phylogeography could shed some light on this long-standing problem was initiated and suggested that a coastal refugium existed in the Pacific Northwest.

Analyses of genetic diversity revealed a lack of molecular differentiation among the Queen Charlotte species, suggesting that these populations may be postglacial in origin and that together N. charlottae, N. louiseae, and N. haida might represent local variations of a single species.

A suite of unique biological features on the Queen Charlotte Islands have led to suggestions that parts of the islands were ice free during the last glacial advance, and Morphological differentiation between marine sticklebacks and some of the highly distinctive freshwater forms was ascribed to rapid post-glacial evolutionary divergence.

The presence of a unique restriction site among geographically isolated populations of Gasterosteus aculeatus suggests that these endemics may have had a common freshwater ancestor that inhabited periglacial freshwater habitats rather than being independently derived from marine forms.
