We summarized the scientific information available for the Alexander Archipelago wolf (Canis lupus ligoni) in the Tongass National Forest of southeast Alaska. Information concerning the morphology, distribution, taxonomy, genetics, and ecology of wolves are presented. Three issues for the conservation of wolves in southeast Alaska are discussed: loss of long-term carrying capacity for deer due primarily to extensive timber harvesting, increased mortality of wolves associated with improved human access from roads, and continued high levels of harvest of wolves by humans.Continued timber harvesting at current levels and by current methods will likely have adverse consequences for some segments of the wolf population. Although some short-term regulatory changes and the management of road access may need to be considered to keep wolf harvest at a sustainable level, the most important consideration is to maintain long-term carrying capacity for deer, the principal prey for most of the wolf population. A series of old-growth forest reserves may provide an effective strategy to increase the likelihood that wolves will persist where extensive timber harvesting has occurred, or is planned.Keywords: Alexander Archipelago wolf, Canis lupus ligoni, effects of logging on wildlife, population dynamics of wolves, predator-prey dynamics, roads and wolf mortality, Tongass National Forest, southeast Alaska.
SummaryThe Alexander Archipelago wolf (Canis lupus ligoni) occupies most of southeast Alaska from Yakutat Bay to Dixon Entrance except for Admiralty, Baranof, and Chichagof Islands. Based on common cranial characteristics, the Alexander Archipelago wolf was considered by early taxonomists to be a distinct subspecies. Recent taxonomic work suggests that these wolves may have originated from a larger subspecific group (C. l. nubilus) that at one time inhabited most of the contiguous Western United States. Wolves probably entered southeast Alaska sometime after the Wisconsin glaciation, following the northward expansion of black-tailed deer (Odocoileus hemionus) along the coast. The hypothesis of a southern origin is supported by recent genetic research showing that wolves in southeast Alaska share a common allele not found in a sample of wolves from interior Alaska or the Yukon. The population is relatively isolated from other wolf populations by water and mountain barriers.A study of the ecology of wolves in southeast Alaska was conducted on Prince of Wales and Kosciusko Islands from 1992 to 1995. Average home-range size of radio-telemetered wolves was 280 square kilometers (109 mi 2 ), with 75 percent of the radio locations for each pack within "core areas" averaging 124 square kilometers (48 mi 2 ). Pack sizes ranged from 2 to 12, with 7 to 9 typical in early autumn. Annual rates of dispersal averaged 39 percent; 71 percent of dispersers were adults ≥2 years old. Dispersal distances were relatively short (13 to 182 kilometers [5 to 71 mi]) presumably due to inter-island water barriers. Wolf movements were more restricted duri...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
