Wolves in the Lower 48 States
BEFORE THE SECRETARY OF THE INTERIOR PETITION FOR A NATIONAL RECOVERY PLAN FOR THE WOLF (CANIS LUPUS) IN THE CONTERMINOUS UNITED STATES OUTSIDE THE SOUTHWEST UNDER THE ENDANGERED SPECIES ACT Center for Biological Diversity Photo: Gary Kramer, U.S. Fish and Wildlife Service 2 July 20, 2010 Ken Salazar, Secretary Rowan Gould, Acting Director Department of the Interior U.S. Fish and Wildlife Service Main Interior Building 1849 C Street NW 18th and C Streets, N.W. Washington, D.C. 20240 Washington, D.C. 20240 Re: Petition to the U.S. Department of Interior and U.S. Fish and Wildlife Service, for Development of a Recovery Plan for the Gray Wolf (Canis lupus) in the Conterminous United States Outside of the Southwest. Dear Secretary Salazar and Acting Director Gould: Pursuant to 16 U.S.C. § 1533(f) of the Endangered Species Act and section 5 U.S.C. § 553 of the Administrative Procedure Act, the Center for Biological Diversity (“Center”) hereby petitions the U.S. Department of the Interior (“DOI”), by and through the U.S. Fish and Wildlife Service (“Service”), to develop a recovery plan for the gray wolf (Canis lupus) in the conterminous United States outside of the Southwest. Our petition excludes the Southwest on the premise that the Mexican gray wolf (Canis lupus baileyi) will be listed either as a subspecies or distinct population segment, as requested in the Center’s Mexican gray wolf listing petition of August 11, 2009. Should this not have occurred by the time the Service initiates development of a recovery plan for the wolf in the conterminous U.S. -
Dingo [Western Australia]
Farmnote 133/2000 : Dingo [Western Australia] Dingo Farmnote 133/2000 By Peter Thomson, Vertebrate Pest Research Section, Forrestfield The dingo or wild dog (Canis familiaris dingo) is found across most of Western Australia. It is subject to management programs in grazing areas because of its predation of livestock. Name 'Dingo' was the name recorded in the early days of European settlement in New South Wales for the 'dogs' belonging to the local Aborigines. 'Warrigal' is one of the central Australian Aboriginal names for the dingo. Although the dingo was classified in the same species as the domestic dog (Canis familiaris), it was probably never exposed to the processes of artificial selection that eventually produced the modern domestic dog. A suggested change in scientific name to Canis lupus dingo reflects the origin of dingoes from wolves (Canis lupus) and the separation of dingoes from domestic dogs. Farmnote 133/2000 : Dingo [Western Australia] Origin The dingo is a primitive dog that evolved from the Indian or Pallid wolf and became widespread throughout southern Asia between 6000 and 10,000 years ago. It is now believed that dingoes were introduced into Australia about 4000 years ago by Asian seafarers, rather than during an Aboriginal migration. Description Dingoes are anatomically very similar to domestic dogs with which they are able to interbreed. They are usually sandy red or ginger in colour, with white feet and a white tail tip. White dingoes and black and tan individuals are also found. Patchy colouration or brindling is a sign of hybridisation with domestic dogs. Occurrence Dingoes are found through much of the state. -
This Is the Authors' Post-Print PDF Version
This is the authors’ post-print PDF version of the paper ‘Wild dogs and village dogs in New Guinea: Were they different?’ which was published in Australian Mammalogy. Citation details for the published version are: Dwyer, P. D. and M. Minnegal (2016) Wild dogs and village dogs in New Guinea: Were they different? Australian Mammalogy 38(1): 1-11. DOI: 10.1071/AM15011 WILD DOGS AND VILLAGE DOGS IN NEW GUINEA: WERE THEY DIFFERENT? PETER D. DWYER and MONICA MINNEGAL Recent accounts of wild-living dogs in New Guinea argue that these animals qualify as an “evolutionarily significant unit” that is distinct from village dogs, have been and remain genetically isolated from village dogs and merit taxonomic recognition at, at least, subspecific level. These accounts have paid little attention to reports concerning village dogs. This paper reviews some of those reports, summarizes observations from the interior lowlands of Western Province and concludes that: (1) at the time of European colonization, wild- living dogs and most, if not all, village dogs of New Guinea comprised a single though heterogeneous gene pool; (2) eventual resolution of the phylogenetic relationships of New Guinea wild-living dogs will apply equally to all or most of the earliest New Guinea village-based dogs; and (3) there remain places where the local village-based population of domestic dogs continues to be dominated by individuals whose genetic inheritance can be traced to pre- colonization canid forebears. At this time, there is no firm basis from which to assign a unique Linnaean name to dogs that live as wild animals at high altitudes of New Guinea. -

Does the Cascade Wolf Survive? Robert Pisano
Does the Cascade Wolf Survive? Robert Pisano The Cascade wolf Cants lupus fuse us is extinct in the USA. But it may survive in Canada, in the coastal forests of British Columbia, the northernmost part of its original range. But British Columbia gives this highly endangered subspecies no special protection. Over-hunting and hybridisation with neighbouring wolf subspecies and domestic dogs are the chief threats. The author reviews wolf management in coastal British Columbia and suggests changes that would improve the Cascade wolfs prospects, including complete protection of all wolves on wilderness islands where it may survive. The grey or timber wolf Canis lupus, ranged over most of North America virtually undisturbed until the European settlers arrived.1 To them, it was a competitor for game and a marauder of domestic stock, and numbers declined dramatically;^ habitat too was inevitably destroyed. As a result 15 of the 27 currently recognised subspecies of North American gray and red wolves are either extinct or highly endangered. Gray wolves are the largest wild canid. In size, weight, pelage and colour they vary considerably among, and often within, subspecies, but generally adult males are between 5 and 6.5 feet from the front of the snout to the tip of the tail, weigh between 45 and 175 pounds, and are grizzled grey with a range from black to nearly pure white. Today four grey wolf subspecies are protected as distinct races: the northern Rocky Mountain wolf C.I. irremotus, the Vancouver Island wolf C.I. crassodon, the Mexican wolf C.I. baileyi and, within its US range only, the eastern timber wolf C. -

Captive Breeding and the Reintroduction
Molecular Ecology (2008) 17, 344–350 doi: 10.1111/j.1365-294X.2007.03400.x CaptiveBlackwell Publishing Ltd breeding and the reintroduction of Mexican and red wolves P. W. HEDRICK and R. J. FREDRICKSON School of Life Sciences, Arizona State University, Tempe, Arizona 85281-4501, USA Abstract Mexican and red wolves were both faced with extinction in the wild until captive popula- tions were established more than two decades ago. These captive populations have been successfully managed genetically to minimize mean kinship and retain genetic variation. Descendants of these animals were subsequently used to start reintroduced populations, which now number about 40–50 Mexican wolves in Arizona and New Mexico and about 100 red wolves in North Carolina. The original captive Mexican wolf population was descended from three founders. Merging this lineage with two other captive lineages, each with two founders, has been successfully carried out in the captive population and is in progress in the reintroduced population. This effort has resulted in increased fitness of cross-lineage wolves, or genetic rescue, in both the captive and reintroduced populations. A number of coyote-red wolf hybrid litters were observed in the late 1990s in the reintroduced red wolf population. Intensive identification and management efforts appear to have resulted in the elimination of this threat. However, population reintroductions of both Mexican and red wolves appear to have reached numbers well below the generally recommended number for recovery and there is no current effort to re-establish other populations.

It has been selectively bred into a wide range of different forms. They are found throughout the world in many different habitats, both closely associated with humans and away from habitation. They are active hunters and have significant negative impacts on a wide range of native fauna. view this species on IUCN Red List Species Description Domestic dogs are believed to have first diverged from wolves around 100,000 years ago. Around 15,000 years ago dogs started diverging into the multitude of different breeds known today. This divergence was possibly triggered by humans changing from a nomadic, hunting based-lifestyle to a more settled, agriculture-based way of life (Vilà et al. 1997). Domestic dogs have been selectively bred for various behaviours, sensory capabilities and physical attributes, including dogs bred for herding livestock (collies, shepherds, etc.), different kinds of hunting (pointers, hounds, etc.), catching rats (small terriers), guarding (mastiffs, chows), helping fishermen with nets (Newfoundlands, poodles), pulling loads (huskies, St. Bernards), guarding carriages and horsemen (Dalmatians), and as companion dogs. Domestic dogs are therefore extremely variable but the basic morphology is that of the grey wolf, the wild ancestor of all domestic dog breeds. -
