Since their range expansion into eastern North America in the mid-1900s, coyotes (Canis latrans) have become the region's top predator. Although widespread across the region, coyote adaptation to eastern forests and use of the broader landscape are not well understood. We studied the distribution and abundance of coyotes by collecting coyote feces from 54 sites across a diversity of landscapes in and around the Adirondacks of northern New York. We then genotyped feces with microsatellites and…

Effects of land cover on coyote abundance
Abstract Context.Throughout the world, declines in large mammalian carnivores have led to the release of smaller meso-mammalian predators. Coyotes (Canis latrans) have increased in abundance,
Diet, Habitat Use, and Size of an Urban Population of Coyotes Obtained Noninvasively
Anthropogenically altered landscapes are novel ecosystems that some species successfully exploit. Canis latrans (Coyote) can attain high densities in urban ecosystems and is of public interest
Coyote colonization of northern Virginia and admixture with Great Lakes wolves
Noninvasive molecular techniques are used to detect the geographic origins of the recent coyote colonization of northern Virginia as a representative of the mid-Atlantic region and to detect signatures of admixture with GLWs.
Spatial genetic analysis of coyotes in New York State
It is suggested that the contact zone between coyote colonization fronts has either eroded or moved further south in New York, indicating that local abundance and ecological context rather than genetic lineage are likely to determine the local ecological effects of coyotes in this region.
Landscape variables associated with relative abundance of generalist mesopredators
Feces counts are used to index the relative abundance of red foxes in a densely forested mountain range, the Black Forest in Germany and it is found that landscape diversity and edge density best predicted differences in feces abundance, both showing a positive correlation with feces abundance.
Effects on white‐tailed deer following eastern coyote colonization
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, is tested.
Resource selection at homesites by wolves and eastern coyotes in a Canis hybrid zone
We modeled resource selection by wolves (Canis spp.), eastern coyotes (C. latrans), and admixed canids during the pup-rearing season at den and rendezvous sites (collectively, homesites) within a
Rapid adaptive evolution of northeastern coyotes via hybridization with wolves
It is suggested that hybridization with wolves in Canada introduced adaptive variation that contributed to larger size, which in turn allowed eastern coyotes to better hunt deer, allowing a more rapid colonization of new areas than coyotes without introgressed wolf genes.
Mapping the expansion of coyotes (Canis latrans) across North and Central America
A detailed account of the original range of coyotes and their subsequent expansion provides the core description of a large scale ecological experiment that can help to better understand the predator-prey interactions, as well as evolution through hybridization.
Can scale-dependent landcover relationships explain canid community composition independent of intraguild occupancy?
Context Niche theory is frequently used as a framework to integrate environmental variables and species interactions to describe species geographic distribution. Yet, the scale at which species


Suitability of the forest landscape for coyotes in northeastern North America and its implications for coexistence with other carnivores
Abstract We compared rural and forest coyotes in northeastern North America under the hypothesis that the forest landscape represents a marginal habitat for this species. We predicted that forest
Summer foraging behaviour of eastern coyotes in rural versus forest landscape: A possible mechanism of source-sink dynamics
Following wolf (Canis lupus) extinction and opening of the forest landscape, coyotes (Canis latrans) progressively colonized eastern North America. In southeastern Quebec, coyotes occur in two
The low performance of forest versus rural coyotes in northeastern North America: Inequality between presence and availability of prey
Abstract Coyotes, which originate from central and southwestern North America, recently extended their range into forests of the Northeast. Forest coyotes occur in lower densities, have lower body
Bobcat–coyote niche relationships during a period of coyote population increase
Resource partitioning between bobcats and coyotes was investigated in eastern Maine during 1979–1984, when colonizing populations of coyotes were rapidly expanding, to investigate activity patterns, spatial relationships, and habitat use.
Coyote Movements, Habitat Use, and Food Habits in Southwestern Oklahoma
Eighteen radio-equipped coyotes (Canis latrans) were found to have home ranges averaging 68.7 km2 for adult females, 31.3 km2 for adult males, 39.9 km2 for yearling females, and 1.0 km2 for pups.
Chronology of Range Expansion of the Coyote, Canis latrans , in New York
Coyotes ( Canis latrans ) were historically restricted to central North America. In less than two centuries, however, Coyotes have colonized most of the continent, including much of northeastern
Home range and habitat use of coyotes in a farm region of Vermont
We studied home ranges, activities, and habitat use of 29 radio-collared coyotes (Canis latrans) representing 11 different social groups in the Champlain Valley of Vermont. Between July 1984 and
Factors influencing killing rates of white-tailed deer by coyotes in eastern Canada
Predation affects the dynamics of many ungulate species. Until recently, little attention has been given to understanding the underlying processes and relationships in predator-prey systems. We
Sciurid Habitat Relationships in Forests Managed Under Selection and Shelterwood Silviculture in Ontario
Abstract Although partial forest harvesting is practiced over large areas, managers know little about its impacts on sciurid rodents, particularly on northern (Glaucomys sabrinus) and southern flying

A spatially explicit population model was used to assess potential effects of predicted changes in snowfall by 2055 on regional marten and lynx populations and suggested that contraction may occur in the core of their current regional range as well as among smaller peripheral populations.
