Presented in a clear and concise style, this book will prove to be an invaluable resource not only for the professional biologist, but the layman as well. Jim Heffelfinger's book breaks the mold. Resource depletion may have contributed to the eventual abandonment of the region during the Medieval Warm Period. The study reveals the presence of heterogeneous vegetation consisting of both woodland and grassland habitats during the late Pleistocene. Epizootic hemorrhagic disease viruses were isolated from seven 18% of the outdoor fawns and all 40 remained clinically normal. The clear, detailed table of contents will help readers flip right to the section they want to investigate. Furthermore, for several subspecies, marked differences in distribution area were found depending on the distribution model used.
According to univariate comparison, both patches may be considered as pertaining to the same landscape element. Measuring trace mineral concentrations can be an important component of assessing the health of free-ranging deer. Twelve of 52 fawns from Texas were moved to an indoor facility. With a clear mission to make his information not only helpful, but entertaining and attractive as well, each chapter focuses on a specific aspect of understanding deer. In this book, anyone interested in deer will be treated to authoritative but nontechnical discussions of deer evolution, natural history, human use, physical characteristics, antler growth, movement, home ranges, density, diets, water requirements, mortality rates, rutting behavior, hybridization, and management.
Factors other than forage were responsible for habitat separation of Big Bend's 2 deer species. The oxygen isotope composition also indicates a diversity of preferences for habitats, including open habitats as well as humid and closed habitats. Deer of the Southwest is a pleasure to read and should be part of every deer enthusiast's library. In treatment areas we erected temporary warning signs equipped with reflective flags and solar-powered flashing amber lights. We evaluated the utility of body and tail hair for measuring selenium, copper, zinc, iron, and manganese in free-ranging mule deer Odocoileus hemionus by using Spearman rank correlations and linear regression.
The clear, detailed table of contents will help readers flip right to the section they want to investigate. The distribution of deer killed by individual mountain lions in areas of exclusive use and areas of overlap was identical to that expected based on the distribution of live deer alone. Growing degree days in this region place the most salient limits on the elevation of maize production and define the region corresponding to a maize-free diet. The test is not in scientific style as this may be a deterrent to many readers, but he cites source information so that anyone interested can review the original articles and draw their own conclusions. Seton 1929 estimated there were approximately 2,000,000 bighorn sheep in the contiguous United States in pristine times; about half were desert bighorn sheep Buechner 1960 Cooperrider 1985. I found the book outstanding because of the width of coverage and the readability. Stomach contents of 25 Carmen Mountains white-tailed deer Odocoileus virginianus carminis and 29 desert mule deer O.
Over much of their range in the U. We could not predict when males would water. Significantly P We determined desert mule deer Odocoileus hemionus crooki watering frequency by monitoring 27 radio-collared deer on 2 study areas in Arizona. His website has been saying another printing is in the works since last year. As a result of applying this tool, strategies for conservation are exposed, and the protocol implemented in the phylogeographic study of white-tailed deer Odocoileus virginianus is defined, to respond to the definition of subspecies and to contribute information for their conservation, management and exploitation. I captured male white-tailed deer Odocoileus virginianus on 2 south Texas ranches and aged them by cementum annuli in an extracted incisor and tooth replacement and wear.
To determine a priori the identity of the pellet samples and evaluate the accuracy of our methods, we obtained samples from individuals in captivity. However, the cementum ages appeared less biased because they predicted a pattern of bias for wear ages equivalent to experience in the literature and gave a more realistic age distribution for the population. They are known to use a variety of habitats, including semi-arid to arid areas Urness, 1981; Wallmo, 1981; Wallmo et al. Jim Heffelfinger has solidified his reputation as the premier authority on deer in this region. Desert bighorn sheep populations of the western United States and Mexico have suffered severe declines due to human impacts. Thus, predation was primarily compensatory. Jim Heffelfinger has crammed a tremendous amount of information into this book.
Se evaluaron 3259 registros de astas de venados cazados entre 1999 y 2009. Precision of the aging techniques was equally poor. To conduct the study we selected segments of 5 highways in 3 western states that were crossed by mule deer during seasonal migrations. Thirty-eight subspecies are recognized, 14 of which occur in Mexico. However, in recent times, numbers are down; drastic habitat alteration and destruction by humans eliminated or reduced desert bighorn herds, and in 1991 approximately 25,000 desert bighorn sheep existed in isolated populations scattered throughout their former range Valdez and Krausman, in press. Hence, in the case of the specimen from Barycz, the observed remodeling process is related to the healing of a fractured velvet antler. The test is not in scientific style as this may be a deterrent to many readers, but he cites source information so that anyone interested can review the original articles and draw their own conclusions.
Evidence derived from gastrointestinal contents, palynological associations, phytolithic analysis, carbon isotopic analyses, and microwear analysis, have shown that Mammut americanum was a browser Green et al. So how soon is soon? Such accounts are supported by ecological, physiographic, and morphological data. Everything you ever wanted to know about these two deer species can be found in its pages. It will be appealing to anyone who likes the long-legged critters. Observed heterozygosity H O was comparable to that of white-tailed deer in the United States H O ¼ 0. The white-tailed deer Odocoileus virginianus occurs over a broad latitudinal range from South America to Canada. Elk Cervus elaphus and mule deer Odocoileus hemionus distribution and use of habitats shared with cattle Bos spp.
Conditions that predispose individual ungulates to mortality are present more often than not in arid environments, and thus managers should not assume that predation is limiting, regardless of predation rates. None of the other correlations and linear associations were found to be sufficiently strong to conclude that hair can reliably be utilized as a complementary sample for measuring these trace mineral concentrations. Despite this drawback, however, both methods appear to be highly accurate. Habitat use by mule deer was studied in the Mapimí Biosphere Reserve in the Chihuahuan Desert, Mexico. Males rubbed more often than females; and in males the rubbing frequency increased in autumn. We found that neither the number of subspecies 13 or 14 of the 38 recognised subspecies , nor the geographical limits between subspecies coincided completely between models. Author Jim Heffelfinger presents a wide array of data in a reader-friendly, well-organized way.
In some areas, observers may misclassify yearling bucks that have shed antlers as juveniles. Some of these genetic markers, found in extant Mexican wolves, reportedly also occur in a few individuals far to the north of the range defined in early accounts. Although it ranges up to 3,600 m Bailey 1931 , the highest densities of Coues' white-tailed deer are found between 1,200 m and 2,100 m Knipe 1977, Heffelfinger 2006. Both enlightening and instructive, Deer of the Southwest is the ultimate source for understanding the history, management, and issues facing this resource. Subordinate individuals rubbed less often, but sniffed more often, particularly at shared rubbing sites. The importation of small game animals suggests that the local supplies could not meet the needs of the community. Such areas should be considered as a high-priority for the con-servation of this species.
