The Animal Damage Control (ADC) program currently relies heavily on aerial gunning in winter to control coyote depredations on mountain grazing allotments. Some people claim that winter aerial gunning is not effective because coyotes migrate to lower elevations during winter, following herds of big game animals, and may not be on the allotments where summer depredations occur. I studied the seasonal movement patterns of coyotes in the Bear River Range of Utah and Idaho to determine if coyotes in montane habitats move on a seasonal basis. Radio-collared coyotes were located from fixed-wing aircraft from 13 November 1987 to 15 September 1989. I used 3 parameters to assess interseasonal movement patterns: overlap in seasonal home ranges, distance between harmonic mean centers of activity, and seasonal differences in mean elevation. All mature coyotes showed overlapping seasonal home ranges, which suggests they did not move substantially between seasons. In contrast, none of the sub-adult coyotes had seasonal home ranges that overlapped. Distances between harmonic centers of seasonal activity were easily assigned to one of two groups (9́Þ5000 m and 9́Þ10,000 m). These corresponded precisely with coyotes that did and did not display overlap in seasonal home ranges. Significant changes in the elevations of seasonal locations were not evident for any age or sex group. I conclude (1) that movement of sub-adult coyotes in the Bear River Range is part of dispersal behavior and is not motivated by seasonal change and (2) that these sub-adult coyotes generally cease wandering during their second years. My findings are similar to other studies where nomadic wandering was more common among sub-adult coyotes and was not correlated with season. I saw no movement of coyotes from the mountains to valley locations. Adult coyotes were in the same location in summer as in winter.

Download or read book Coyote Movement Patterns with Emphasis on Home Range Characteristics written by Stephen J. Hibler and published by . This book was released on 1977 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Standard radio telemetry techniques via triangulation were used to determine coyote locations and to construct maps of coyote movement patterns in Curlew Valley (Utah and Idaho). Home range sizes were determined by establishing corresponding boundaries drawn on the basis of location, density and relative number of visitations (contour method), and then tracing the boundaries with a compensating polar planimeter. Mean home range sizes were determined directly for only those animals with home range values that reached an asymptote when plotted against corresponding time periods. This asymptotic value was considered the best estimate of the actual home range size. Four adult females and one adult male were in this category, with mean values of 18.3 km2 and 14.5 km2 respectively . The asymptote was estimated for home ranges which did not stabilize (mean values of 20.2 and 17.8 km for adult females and males respectively) using a home range estimator; validation of the estimator is discussed. Since no juvenile animal 's home range appeared to reach an asymptote, no asymptotic estimates were made . Various methods of constructing home range boundaries, their advantages and disadvantages, are listed. Standardization in the home range concept is necessary if meaningful comparisons are to be made between studies. Home ranges are dynamic, and must be considered in terms of specific time frames. Guidelines for adequate description of the home range are discussed with emphasis on quantity of data, time requirements and recognition of seasonal shifts in the home range. Map analysis suggested three general patterns with regard to home ranges; namely, animals with contiguous home range areas, those with disjunct home ranges, and wandering individuals. Fifty percent of the coyotes were trapped more than 0.5 km outside home range boundaries while an additional 42 percent were trapped on the periphery of the home range. Only 8 percent, all juveniles, were trapped within their home range. None of the 21 animals killed by hunters or trappers died well within their respective home ranges. Twenty-nine percent were killed on the periphery of their home ranges and 71 percent were killed an average of 11 km outside their home range ~n℗ʺ℗ʺ~rl~Ties. Several movement patterns other than home range were discernible, including brief excursions away from the home range (sallies), dispersals, and total area utilized. Mean dispersal distances for adul t males, juvenile males and females respectively were 56, 9 and 54 km; no adult female was known to disperse. Juvenile females had the greatest tendency to disperse with 53 percent involved; juvenile males, 33 percent and adult males, 30 percent. Sallies were analyzed according to distance, duration and frequency, with adult females having the longest (4.9 km) and the greatest number of sallies (7.9 per month), and adult males spending the most time per sally (16.2 hours) as well as time per month (72.9 hours) in sally activity. The total area utilized by coyotes is discussed in terms of size and measurement. Mean values for total areas utilized are 138 km2 for adult females, 90 km 2 for adult males, 68 km2 for juvenile males and 46 km 2 for juvenile females. Home range configuration is discussed in terms of importance and variability in form, with the majority of shapes being ameboid in character. Linearity may be a function of the method used to establish home range boundaries and use of baseline data from fixed radio telemetry stations.

Book excerpt: Xiaoming Wang and Richard H. Tedford combine their research with Mauricio Anton's impeccable reconstructions to present a remarkable portrait of canids over the past 40 million years. Wang and Tedford cull their history from the most recent scientific research conducted on the vast collections of the American Museum of Natural History and other leading institutions. With their rich fossil record, diverse adaptations to various environments, and different predatory specializations, canids are an ideal model organism for the mapping of predator behavior and morphological specializations. They also offer an excellent contrast to felids, which remain entrenched in extreme predatory specializations. The innovative illustrated approach of this book transforms the science of paleontology into a thrilling visual experience, and it forms the perfect accompaniment to an extremely important branch of animal and fossil study.

Available in PDF, EPUB and Kindle. Book excerpt: When I first proposed a series entitled Current Mammalogy to the pub lishers, they were reluctant to undertake such a project because they viewed the field of mammology as overly fragmented. At first I found this idea to be difficult to accept; however, upon reflection, I came near to agreeing with it. Although many of us work on mammals, we gen erally feel more allegiance to our specialties, such as systematics, ge netics, cytogenetics, ecology, behavior, pest control, paleontology, wildlife management, primatology, and marine mammalogy, than we do to the general field of mammalogy. However, rather than becoming discour aged from pursuing this project, I became more certain than ever that a series such as Current Mammalogy was needed. We hope to make this series a place where specialists can present their ideas not only to other members of their specialty, but to those outside the area as well. Hopefully, this exchange of ideas will be a mutually beneficial exercise. The Editorial Board of Current Mammalogy has decided to keep the range of subjects in each volume as broad as possible rather than concentrating on one or two topics, in the hope that this will keep the series as useful as possible to the broadest range of readers.

This book was released on 2021-03-09 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: A natural history and celebration of the famous bears and salmon of Brooks River. On the Alaska Peninsula, where exceptional landscapes are commonplace, a small river attracts attention far beyond its scale. Each year, from summer to early fall, brown bears and salmon gather at Brooks River to create one of North America’s greatest wildlife spectacles. As the salmon leap from the cascade, dozens of bears are there to catch them (with as many as forty-three bears sighted in a single day), and thousands of people come to watch in person or on the National Park Service’s popular Brooks Falls Bearcam. The Bears of Brooks Falls tells the story of this region and the bears that made it famous in three parts. The first forms an ecological history of the region, from its dormancy 30,000 years ago to the volcanic events that transformed it into the Valley of Ten Thousand Smokes. The central and longest section is a deep dive into the lives of the wildlife along the Brooks River, especially the bears and salmon. Readers will learn about the bears’ winter hibernation, mating season, hunting rituals, migration patterns, and their relationship with Alaska’s changing environment. Finally, the book explores the human impact, both positive and negative, on this special region and its wild population.

Book excerpt: This cooperative effort by USDA Forest Service Research and the National Forest System assesses the state of knowledge related to the conservation status of four forest carnivores in the western United States: American marten, fisher, lynx, and wolverine. The conservation assessment reviews the biology and ecology of these species. It also discusses management considerations stemming from what is known and identifies information needed. Overall, we found huge knowledge gaps that make it difficult to evaluate the species' conservation status.
Download or read book Carnivore Behavior Ecology and Evolution written by John L. Gittleman and published by Cornell University Press. This book was released on 2019-05-15 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mammalian order Carnivora is characterized by an incredible range of morphological, ecological, and behavioral variation. Carnivores can be as small as the 100-gram least weasel or as large as the 800-kilogram polar bear. Their reproductive rate can vary from one offspring every five years, as with some black bears, to three litters a year, as with the dwarf mongoose. Group sizes can be traced along a wide continuum, from the solitary ermine to the monogamous golden jackal to the large extended packs of as many as 80 spotted hyenas. Until recently the general habits of most wild carnivore species were inadequately understood. In the last decade, however, improved technologies, including the use of radiotelemetry and night-vision scopes, have led to many important discoveries. This book is at once a critical summary and an evaluation of current research on carnivores. A worthy successor to R.F. Ewer's monumental volume, The Carnivores (Cornell University Press), it is the work of 30 leading carnivore biologists, who here assemble comparative data on the basic anatomical, behavioral, ecological, physiological, reproductive, and evolutionary characteristics of this group. After a general introduction to the Carnivora, the volume is divided in three parts, each of which begins with a brief introduction outlining its main themes. Part I, Behavior, covers acoustic and olfactory communication, behavioral development, behavioral ecology of canids and hyaenids, modes of solitary living, and group living. In Part II, Ecology, topics include feeding ecology of the giant panda and Asiatic black bear, adatpations for aquatic living, ecological constraints on predation in felids, consequences of small size in mustelids, rate of basal metabolism and food habits, and reproductive output. Part III, Evolution, deals with the morphological approaches to phylogeny, and the fossil record. An appendix presents a complete classification of the Carnivora, including topics of continuing controversy. Highlighting recent developments in the study of the Carnivora and areas for further research, this broad synthesis will be of great value of students and researchers in animal behavior, behavioral ecology, wildlife ecology, mammalogy, paleontology, systematics, and evolution theory. It will also encourage realistic conservation programs to manage rapidly diminishing populations and will elucidate particular features of the carnivores for nonspecialist readers.
