	MITES - CLASSIFICATION AND DIVERSITY (Site not responding. Last check: 2007-10-12)
		Members of Huitfeldtia rectipes Thor, a holarctic mite that occurs throughout Boreal and Arctic Ecozones, inhabit the profundal zone of oligotrophic lakes in the Mixedwood Plains at the southern limit of the distribution for the species (Smith 1976a).
		Several holarctic genera are represented in the Ecozone by one or two common species with either Northeastern or Boreal distributions (Smith 1977b).
		Several species in the holarctic genera Aturus and Kongsbergia are among the dominant mites in stream riffles in the Ecozone (Fig.M-34), but these taxa have not yet been well studied and species identities remain uncertain.

	Cucujidae
		The family is represented on all continents except Africa, but is richest in the Holarctic Region.
		Cucujus is Holarctic in distribution, with one species, represented by two subspecies, currently recognized from North America.
		The largest genus, Pediacus, is also Holarctic, but in the New World extends its distribution south into the Neotropics in Central America at high altitudes.

	Holarctic biogeography of Agonum carabid beetles: Illuminating area relationships through time (Site not responding. Last check: 2007-10-12)
		Using morphological characters we have deduced a phylogenetic hypothesis for the natural entities comprising this group, rooting the cladogram at the African sister group Agonidium.
		Distributional ranges vary tremendously among the species; some are peripheral isolates occupying only a fraction of the range of the adelphotaxon, others are broadly sympatric assemblages of related species, which in some instances span hemispheres.
		This occurrence of many widespread, sympatric species is typical for many Holarctic groups, who have diversified prior to the great perturbations of Pleistocene glaciation.

		On the Zoogeography of the Holarctic Region, by Karl Patterson Schmidt
		None of these genera are confined to the two areas nor, indeed, to the Holarctic Region, and thus they do not contribute evidence of special relationship between the faunae.
		suggest that the existing resemblances between eastern Asia and eastern America are all that remain of a wide-spread Holarctic fauna of an earlier period, and one in numerous respects peripheral to the Holarctic fauna of the present day.

	History of the North American Bird Fauna, by Ernst Mayr
		Second, there are certain groups ("holarctic," or "panboreal," elements) which have moved back and forth across Bering Strait so freely that they cannot be assigned with certainty to either continent.
		It was much neglected in the past, when some of its components were labelled "Holarctic," others "Neotropical." The greater part of the Tertiary North American continent had a subtropical or tropical climate, as mentioned above, and it is therefore not surprising that tropical families and genera are well represented in this North American element.
		It is not justifiable, as far as birds are concerned, to include North America either in a "Neotropical" or in a "Holarctic" region, since the autochthonous North American element comprises up to 50 per cent, or even more, of the North American fauna in all habitats except the arctic.

		These are koinobiont endoparasitoids of Symphyta and, rarely, Lepidoptera; oviposition is into the egg or larva, with emergence after the host cocoon is spun.
		The biology is unknown but they are Holarctic in distribution; two genera.
		Townes (1969) originally placed the two genera as a tribe in the Banchinae but later (1970b) put them in a separate subfamily on the basis of adult, larval, and biological characters.

	Biogeography of wolverine (Gulo gulo)
		Wolverines have a Holarctic distribution, from Scandinavia through eastern Europe, Russia, and Siberia to Alaska, Canada, and the western United States (Sleeper 1995).
		The Mustelidae appear to have originated late in the Eocene from the ancestral, Holarctic Miacidae family, but the early stages of their evolutionary history are difficult to trace, mainly because of their forest habitat (Ewer 1973).
		The immigrations of mustelids out of the Holarctic and into South America happened in the Quaternary (Gittleman 1996).

		), a large-horned species, was evidently well-adapted to cool steppe-like grasslands that existed throughout the Holarctic region (northern Eurasia and North America) from England eastward to the Northwest Territories of Canada during the Pleistocene (about 2 million to 10,000 years ago).
		With the small horse and woolly mammoth, it is one of the commonest species known from Eastern Beringia (unglaciated parts of Alaska, Yukon and adjacent areas of the Northwest Territories).
		The species spread eastward to England and westward to the Beaufort Sea coast of the Northwest Territories, and possibly some herds were forced farther southward and eastward (e.g.

	Studia dipterologica Supplement - Volume 4
		It is the author's purpose to make a contribution to the amelioration of this unsatisfactory situation.
		The present work offers a revision of the "Lestremiinae" which, for the first time, covers the entire Holarctic region.
		A standardised terminology and a fresh attempt at the discovery and evaluation of characters provide the basis for a comparative morphological study of the adult stage.

		Waterfowl are an important migratory component of the Holarctic avifauna, and their phylogeography and population genetics at high latitudes can provide insight into how these climatologically variable regions have affected avian lineages.
		The Mallard (Anas platyrhynchos) is the most numerous and well-known waterfowl species with a Holarctic distribution and thus serves as a model for waterfowl studies in the Holarctic.
		In addition to providing insight into how strong seasonality, concordant seasonal migration, and historical processes have affected Holarctic avian lineages, knowledge of Mallard population structure and distribution is necessary to develop measures for management, because the Mallard is the most popular game duck in Eurasia and North America.

	Odonata (Damselflies and Dragonflies) Chapter: Assessment of species diversity in the Montane Cordillera Ecozone (Site not responding. Last check: 2007-10-12)
		The majority of the 76 species known from the Montane Cordillera Ecozone are restricted to the Nearctic region, although six are holarctic (defined here as species with transcontinental ranges in both North America and Eurasia).
		This section describes the Nearctic faunal elements pertaining to the ecozone (species with holarctic distributions are also assigned to a North American faunal element).
		In general, these species range from the Atlantic Provinces across the northern New England states, Quebec, northern Ontario, parts of the northern tier of mid-western states, the Prairie Provinces north of the Great Plains, and northern British Columbia, often ranging cosiderably southward in the higher mountains and plateaus of the western Cordillera.

	Birds and Nature: The Geographical Distribution of Birds
		When we understand that at least one-third of the species found in the Nearctic are also found in the Palearctic, we shall understand why these two are grouped under one region.
		Indeed, there are few species which nest in both the Holarctic and in the regions bounding it on the south, and many of these are found only on the southern boundaries of the Holarctic.
		In our part of the Holarctic, that is, the Nearctic, the familiar birds about us do not nest also in the tropical regions.

	Prater & Marchant & Vuorinen. Guide to the Identification and Ageing of Holarctic Waders
		In covering all the waders of Eurasia (excluding India and southeast Asia), North America and North Africa - 117 species or 58% of the world total - the need for the first detailed guide to waders has been fulfilled with laudable overkill.
		Species breeding in the Holarctic are treated in detail - with emphasis on the most numerous ones - under headings of identification, ageing, sexing, geographical variation and biometrics.
		For irregular breeders and vagrants, only the basic identification criteria are given.
