Book excerpt: Excerpt from Revision of American Voles of the Genus Microtus Certain peculiarities of habits are common to nearly all of the Species. None are known to hibernate, but in the North they have snug winter homes under the snow, where they move about freely in numberless tun nels. They burrow in the ground, and are famous for their little roads or smooth trails which run through the grass from burrow to burrow or away to their feeding grounds. Bulky nests of grass and soft plant fibers are placed in underground cavities, or on the surface of the ground under cover of snow, logs, or dense vegetation. The nest is depressed globular in form, with an open chamber in the center, which contains a soft bed, ' and has one or two round entrances at the sides. These nests are the sleeping places of the old and the nurseries of the young. They are kept surprisingly clean and fresh, and new ones are frequently'made to take the place of those that are Old or imperfect. Breeding. - Voles seem to have no definite breeding season. Four to eight young are usually produced at a birth, and as far north as Min nesota I have found them in the nests at all seasons of the year. Their increase is accordingly very rapid, and is only partially counter balanced by the host of enemies that prey upon them. They form the principal food of nearly all owls and some hawks, while weasels, minks, foxes, coyotes, cats, badgers, skunks, and many other animals, as well as certain snakes, feed extensively on them. But in spite of their enemies they seem to hold their own, and tend to increase faster as the country becomes more thickly settled and the larger mammals and birds are destroyed.

Available in PDF, EPUB and Kindle. Book excerpt: 4.1.1 Demographic significance Confined populations grow more rapidly than populations from which dispersal is permitted (Lidicker, 1975; Krebs, 1979; Tamarin et at., 1984), and demography in island populations where dispersal is restricted differs greatly from nearby mainland populations (Lidicker, 1973; Tamarin, 1977, 1978; Gliwicz, 1980), clearly demonstrating the demographic signi ficance of dispersal. The prevalence of dispersal in rapidly expanding populations is held to be the best evidence for presaturation dispersal. Because dispersal reduces the growth rate of source populations, it is generally believed that emigration is not balanced by immigration, and that mortality of emigrants occurs as a result of movement into a 'sink' of unfavourable habitat. If such dispersal is age- or sex-biased, the demo graphy of the population is markedly affected, as a consequence of differ ences in mortality in the dispersive sex or age class. Habitat heterogeneity consequently underlies this interpretation of dispersal and its demographic consequences, although the spatial variability of environments is rarely assessed in dispersal studies.

Available in PDF, EPUB and Kindle. Book excerpt: The boreal forest is one of the world's great ecosystems, stretching across North America and Eurasia in an unbroken band and containing about 25% of the world's closed canopy forests. The Kluane Boreal Forest Ecosystem Project was a 10-year study by nine of Canada's leading ecologists to unravel the impact of the snowshoe hare cycle on the plants and the other vertebrate species in the boreal forest. In much of the boreal forest, the snowshoe hare acts as a keystone herbivore, fluctuating in 9-10 year cycles, and dragging along secondary cycles in predators such as lynx and great-horned owls. By manipulating the ecosystem on a large scale from the bottom via fertilizer additions and from the top by predator exclosures, they have traced the plant-herbivore relationships and the predator-prey relationships in this ecosystem to try to answer the question of what drives small mammal population cycles. This study is unique in being large scale and experimental on a relatively simple ecosystem, with the overall goal of defining what determines community structure in the boreal forest. Ecosystem Dynamics of the Boreal Forest: The Kluane Project summarizes these findings, weaving new discoveries of the role of herbivores-turned-predators, compensatory plant growth, and predators-eating-predators with an ecological story rich in details and clear in its findings of a community where predation plays a key role in determining the fate of individuals and populations. The study of the Kluane boreal forest raises key questions about the scale of conservation required for boreal forest communities and the many mammals and birds that live there.

Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Ultrasonic Vocalization: Window into the Mammalian Brain, Volume 25, is an exhaustive resource on ultrasonic vocalizations in vertebrates, providing full coverage of all aspects of these vocalizations. The book also demonstrates the usefulness of ultrasonic vocalizations in studies of animal communication, sociobiological states, and in mammalian models of affective disorders, addictions and neurodevelopmental disorders, making it an indispensable resource for researchers using animal models. The book begins with the evolution of vocal communication before discussing mechanisms of ultrasound production, perception and the brain systems involved in emotional arousal that are responsible for the generation of vocalization and emotional states. In addition, the book covers studies of neuroactive agents and sociopsychological conditions that can regulate the outcome of ultrasonic vocalization and provide clues about animals’ internal states. Critically, the book also includes thorough coverage of pharmacological investigations using ultrasonic vocalizations, increasingly being utilized for studies in affective disorders, psychoses, addiction and alcoholism. No other book provides such extensive coverage of this rapidly growing field of study. Represents a multidisciplinary approach that incorporates evolution, communication, behavioral homeostasis, emotional expression and neuropsychiatric dysfunction Provides a systematic review of ultrasonic vocalizations in major groups of rodents widely used in laboratory research Discusses numerous other species across vertebrates that emit ultrasounds

Download or read book Public Health Significance of Urban Pests written by Xavier Bonnefoy and published by World Health Organization. This book was released on 2008 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second half of the 20th century and the beginning of the 21st century witnessed important changes in ecology, climate and human behaviour that favoured the development of urban pests. Most alarmingly, urban planners now face the dramatic expansion of urban sprawl, in which city suburbs are growing into the natural habitats of ticks, rodents and other pests. Also, many city managers now erroneously assume that pest-borne diseases are relics of the past. All these changes make timely a new analysis of the direct and indirect effects of present-day urban pests on health. Such an analysis should lead to the development of strategies to manage them and reduce the risk of exposure. To this end, WHO invited international experts in various fields - pests, pest-related diseases and pest management - to provide evidence on which to base policies. These experts identified the public health risk posed by various pests and appropriate measures to prevent and control them. This book presents their conclusions and formulates policy options for all levels of decision-making to manage pests and pest-related diseases in the future. [Ed.]
