“…Similarly, coyote harvests from Washington increased from the five -year period ending 1964-1965 (mean = 362/year) to the five years ending . Consistent with this, coyotes were rare or nonexistent in coniferous forests of the Oregon and Washington Cascades until timber wolves were extirpated around 1930 (Ozoga and Harger 1966).…”

“…Numerous reports describe coyotes accessing high-elevation, deep snow areas by moving along paths, roads, and snowshoe hare trails (Bider 1962;Ozoga and Harger 1966;. Unpublished data from Oregon (USDA Forest Service, unpublished report) and Colorado (Byrne 1998, unpublished) also suggest that coyotes use high elevation areas, although their means of access is not known.…”

Once found throughout the Rocky Mountains and forests of the northern states, the lynx now hides in pockets of its former range while feeding mostly on small animals like snowshoe hares. A team of government and university scientists review the newest scientific knowledge of this unique cat's history, distribution, and ecology. The chapters on this web site provide information for current scientific and public debates regarding the fate of the lynx in the United States. Chapters look at the relationships among lynx, its habitat, and its prey. The attributes of northern versus southern lynx populations are compared and contrasted. The authors caution against making decisions without enough knowledge and show where we lack information. While the authors present the latest preliminary research results on lynx and offer some qualified insights into lynx management, the book's intent is to assess the current state of knowledge regarding lynx.Hard copies of the report will be available in late 1999 from the University Press of Colorado,

“…Arjo and Pletscher (47) hypothesized that this pack structure change was for defense against wolves, and the dietary change was an increase in scavenging of carcasses left by wolves. Increased pack size in coyotes also has important offensive consequences for prey-killing, and many studies have documented that coyotes in large packs kill ungulate prey (10,(48)(49)(50).…”

“…In this case, it was probably a combination of both. For example, competition with larger predators causes coyotes to form larger packs for defense (47), which makes them better able to catch larger prey as a team (48)(49)(50).…”

Living coyotes modify their behavior in the presence of larger carnivores, such as wolves. However, little is known about the effects of competitor presence or absence on morphological change in coyotes or wolves over long periods of time. We examined the evolution of coyotes and wolves through time from the late Pleistocene, during which many large carnivorous species coexisted as predators and competitors, to the Recent; this allowed us to investigate evolutionary changes in these species in response to climate change and megafaunal extinctions at the end of the Pleistocene. We measured postcranial skeletal morphologies of wolves (Canis lupus) and coyotes (C. latrans) from Pleistocene-aged tar deposits, as well as early, mid, and recent Holocene populations of both. We found few morphological differences between Pleistocene and Holocene wolf populations. Conversely, we found many differences in coyotes: Pleistocene coyotes were larger and more robust than Holocene populations. However, within 1,000 y of the megafaunal extinctions, coyotes are morphologically indistinguishable from modern populations. We cannot attribute these differences directly to climate change because modern coyotes do not follow Bergmann's rule, which states body size increases with decreasing temperature. Instead, we suggest that Pleistocene coyotes may have been larger and more robust in response to larger competitors and a larger-bodied prey base. Although we cannot separate competition from predator-prey interactions, this study indicates that the effects of biotic interactions can be detected in the fossil record.Pleistocene extinctions | Canidae | Rancho La Brea

“…KREBS (1978) atribuiu esta a fatores tanto evolutivos como comportamentais. A estrutura da vegetação, alimento e elementos florísticos específicos (espécies de plantas que influenciam a distribuição de certos animais), bem como os recursos alimentares, são os fatores que mais influenciam na preferência de hábitat em carnívoros (YARSLEY & SAMUEL, 1980;CEBALLOS & GALINDO, 1984;OZAGA & HARGER, 1996;ZALAPA et al, 1998).…”

ABSTRACT. Carnivore mammals and their relation with habitat diversity in Aparados da Serra National Park, southern Brazil. A survey of carnivore mammals was accomplished in Aparados da Serra National Park from February 1998 to March 2000. The park has 10,250 ha and is considered a biodiversity core area of the Atlantic Forest Biosphere Reserve in the Rio Grande do Sul State, Brazil. The landscape is characterized by relatively well preserved relicts of Araucaria angustifolia (Bertol.) Kuntze forest, grasslands and Atlantic Forest, which have contributed for the survival of endangered carnivore mammals. The National Park was divided in a grid of 16 km 2 cells using a 1:50,000 scale map. The animals were recorded using indirect methods, by identifying signs (scats, tracks) and direct observation in 2.5 km long and 5 m wide transects, with 10 replicates in each grid cell. Interviews with local people were also used to confirm the animal presence. A total of 13 species was recorded: Procyon cancrivorus (Cuvier, 1798), Pseudalopex gymnocercus (G. Fischer, 1814), Leopardus pardalis (Linnaeus, 1758) and Cerdocyon thous (Linnaeus, 1766) were the most frequent species registered. Nasua nasua (Linnaeus 1766), Herpailurus yaguarondi (Lacépède, 1809), Chrysocyon brachyurus (Illiger, 1815), Eira barbara (Linnaeus, 1758), Leopardus sp., Puma concolor (Linnaeus, 1771), Galictis cuja (Molina, 1782), Conepatus chinga (Molina, 1892) and Lontra longicaudis (Olfers, 1818) showed lower frequencies. The Park presented areas with significant differences (Mantel Test, P< 0.05) in species richness and composition related to habitat classes. Areas with high habitat richness presented high species richness. The Araucaria forest was the habitat that presented the higher carnivore richness. The border areas of the Park are influenced by several environmental degradation factors that could be affecting the distribution of carnivores.
