Email [email protected] * Correspondence author Keywords: Canis latrans, Canis lycaon, Canis lupus, Canis oriens, cladogamy, coyote, coywolf, eastern coyote, eastern wolf, hybridisation, meta-analysis, northeastern coyote, wolf. Abstract A flurry of recent papers have attempted to taxonomically characterise eastern canids, mainly grey wolves Canis lupus, eastern wolves Canis lycaon or Canis lupus lycaon and northeastern coyotes or coywolves Canis latrans, Canis latrans var. or Canis latrans x C. lycaon, in northeastern North America. In this paper, we performed a meta-analysis on northeastern coyote taxonomy by comparing results across studies to synthesise what is known about genetic admixture and taxonomy of this animal. Hybridisation or cladogamy (the crossing between any given clades) be- tween coyotes, wolves and domestic dogs created the northeastern coyote, but the animal now has little genetic in- put from its parental species across the majority of its northeastern North American (e.g. the New England states) range except in areas where they overlap, such as southeastern Canada, Ohio and Pennsylvania, and the mid- Atlantic area. The northeastern coyote has roughly 60% genetic influence from coyote, 30% wolf and 10% domestic dog Canis lupus familiaris or Canis familiaris. There is still disagreement about the amount of eastern wolf versus grey wolf in its genome, and additional SNP genotyping needs to sample known eastern wolves from Algonquin Pro- vincial Park, Ontario to verify this.

Réclamée pour aider à améliorer les perspectives décroissantes des industries du charbon et de l’acier du Cap-Breton, la chaussée a aussi eu un impact immense en élevant le tourisme au rang d’une industrie viable, le Cap-Breton étant une communauté écossaise traditionnelle et désormais accessible. Le tourisme et l’expansion industrielle ont été étroitement liés à un important changement de cap des politiques du gouvernement fédéral, qui a alors commencé à assumer un rôle plus interventionniste dans la planification du développement économique régional, ce qui leur a été profitable. This article assesses the conceptualization, construction, and mythologizing of the Canso Causeway, a major post-Second World War reconstruction project that joined mainland Nova Scotia to Cape Breton Island in 1955. Sought after in order to help improve the waning prospects of Cape Breton’s coal and steel industries, the causeway also had a tremendous impact on increasing tourism as a viable industry based on Cape Breton as a traditional but accessible Scottish community. Both tourism and industrial expansion were closely tied to and benefited from a significant policy shift as the federal government began to assume a more interventionist role in regional economic development planning.

  • White-Tailed Deer, Coyotes, and the Ecology of Fear in a Longleaf
    WHITE-TAILED DEER, COYOTES, AND THE ECOLOGY OF FEAR IN A LONGLEAF PINE SAVANNA By MICHAEL JOHN CHERRY (Under the Direction of Robert J. Warren) Abstract Predators can exert powerful influence on their prey, independent of direct killing, by inducing antipredator responses. Coyotes (Canis latrans) have recently achieved abundances capable of influencing white-tailed deer (Odocoileus virginianus) population demography in the southeastern USA, but the effects of antipredator responses have not been reported. I conducted a multifaceted investigation of coyote and white-tailed deer interactions, using population monitoring data, harvest data, and results from controlled experimentation with predator exclosures. This work provided evidence that coyotes can influence white-tailed deer space use and vigilance while foraging, and documented a negative relationship between coyote abundance and body mass of adult female deer during an 11-year period. I compared multiple measures of reproductive success during a 7-year period that encompassed high and low coyote-deer ratios to elucidate the relative contributions of direct predation and predation risk effects to an observed increase on recruitment as measured by fawn-adult female ratios. Fawn survival rates were similar between periods, but the proportion of females with evidence of ovulation increased during the period of low coyote-deer ratios. Increases in ovulation were similar to increases in the proportion of females with evidence of lactation and fawn-adult female ratios. While direct killing by predators greatly influenced survival of fawns during both periods, changes in recruitment resulted from variations in fecundity. I tested hypotheses predicting the consequences of 10 years of predator exclusion on oak (Quercus sp.) recruitment and the density of selected deer forage species.

The Committee is composed of representatives of the Department of Regional Economic Expansion, Environment Canada and Transport Canada, and of the Department of the Environment, Department of Development and Department of Municipal Affairs of the Province of Nova Scotia. The Strait of Canso Environment Committee has as its first objective the development of an environmental management strategy proposal for the Strait of Canso area. Regional environmental assessment and environmental management programs must necessarily be based upon a comprehensive and integrated knowledge of the physical, social and economic resource base ofthe region. Toward this end, the Committee arranged for an initial program, funded under a Federal-Provincial agreement, comprising an inventory of existing information on the natural environment of the Strait of Canso region. The inventory of natural resources and resource uses commenced the summer of 1974, leading to the presentation of the information in a series of special maps and accompanying reports for publication and distribution in late 1975 and early 1976.

SCOTT MILLS, Wildlife Biology Program and Of®ce of Research and Creative Scholarship, University of Montana, Missoula, MT 59812, USA ABSTRACT The expansion or recovery of predators can affect local prey populations. Since the 1940s, coyotes (Canis latrans) have expanded into eastern North America where they are now the largest predator and prey on white-tailed deer (Odocoileus virginianus). However, their effect on deer populations remains controversial. We tested the hypothesis that coyotes, as a novel predator, would affect deer population dynamics across large spatial scales, and the strongest effects would occur after a time lag following initial coyote colonization that allows for the predator populations to grow. We evaluated deer population trends from 1981 to 2014 in 384 counties of 6 eastern states in the United States with linear mixed models.

  • Coyotes, Look Christine to Their Wolf Relatives Schadler
    To understand By Eastern coyotes, look Christine to their wolf relatives Schadler housands of Eastern coyotes live among us – rarely seen, often heard and frequently discussed. Some T people resent the presence of coyotes and fear them as predators of pets, livestock and game animals. Others admire their resilience, and are thrilled to hear their return- to-the-wild howl and all it represents. In short, the coyote is a topic of contention. The Eastern coyote (Canis latrans var.) and the Eastern wolf (Canis lupus lycaon) are closely related and similar enough in appearance that it can be hard to distinguish them. Yet coyotes are abundant throughout their range in the face of liberal hunting and trapping seasons, while the wolf is protected by the Endangered Species Act. The answer to this dichotomy lies in the apparent vulnerability of the wolf and the undeniable success of the coyote. Susceptible to overhunting and habitat loss, wolves in the lower 48 were nearly eradicated over a century ago. Today, wolves roam through- out the West and the Great Lake states, saved by protection and reintroductions. The coyote’s success, on the other hand, has created a public relations night- mare for itself. Despite over a century of relentless persecution, coyotes have thwarted every effort at control and have expanded their range into the densely settled East Coast. Studies show that where coyote bounties (paying hunters to kill coyotes), open hunting seasons, poisoning, snaring and other control measures have been attempted, success varies depending on scale. Nationwide, there are tens of 8 November/December 2010 • WILDLIFE JOURNAL O T PHO S AM AD AY AY NDS © LI WILDLIFEILDLIFE JJOURNAL •• November/December 2010 9 Wolf or Coyote?
