Download or read book The Pantanal of Pocon written by Charles W. Heckman and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many famous wetlands in the world that have been deemed important for the homeostasis ofthe biosphere and accorded some form ofprotected status in view of the richness of their flora and fauna. T}1e Pantanal, located almost directly in the center ofthe South American continent, is among the largest such wetlands in the world. It is, in fact, the largest wetland that is still in a nearly natural state and has not been extensively modified by man for agriculture. The extent of the region covered by flood waters at the end of each rainy season varies from year to year, sometimes considerably, so estimates of the exact area it occupies have varied enormously. The size of the 2 2 Pantanal has been reported to be between 80,000 km (Bonetto, 1975) and 250,000 km (Tundisi and Matsumura-Tundisi, 1985). The most co~on1y accepted estimates at the present time are approximately 130,000 to 140,000 km , supported by estimates made from Nimbus-7 satellite observations (Hamilton et al. , 1996). However, Por (1995) suggested that the area extending into Bolivia and Paraguay has not been satisfactorily 2 surveyed, leading him to accept the figure of 200,000 km as the area of the entire Pantanal, ineluding all of its extensions. The main reason for the year to year variation in the extent of the flooding is the considerable difference in timing of the rainfall on the watershed.

Download or read book Bird Nests and Construction Behaviour written by Mike Hansell and published by Cambridge University Press. This book was released on 2000-08-31 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bird Nests and Construction Behaviour provides a broad view of our understanding of the biology of the nests, bowers and tools made by birds. It illustrates how, among vertebrates, the building abilities of birds are more impressive and consistent than for any other builders other than ourselves, yet birds seem to require no special equipment, and use quite uncomplicated behaviour. In doing so, the book raises general issues in the field of behavioural ecology including the costs of reproduction, sexual selection and the organisation and complexity of behaviour. Written for students and researchers of animal behaviour, behavioural ecology and ornithology, it will nevertheless make fascinating reading for architects and engineers interested in understanding how structures are created by animals.

Download or read book Neotropical Hard Ticks Acari Ixodida Ixodidae written by Alberto A. Guglielmone and published by Springer Nature. This book was released on 2021-07-29 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of the 758 species of hard ticks (family Ixodidae) currently known to science, 137 (18%) are found in the Neotropical Zoogeographic Region, an area that extends from the eastern and western flanks of the Mexican Plateau southward to southern Argentina and Chile and that also includes the Greater and Lesser Antilles and the Galápagos Islands. This vast and biotically rich region has long attracted natural scientists, with the result that the literature on Neotropical ticks, which are second only to mosquitoes as vectors of human disease and are of paramount veterinary importance, is enormous, diffuse, and often inaccessible to non-specialists. In this book, three leading authorities on the Ixodidae have combined their talents to produce a summary of essential information for every Neotropical tick species. Under each species name, readers will find an account of the original taxonomic description and subsequent redescriptions, followed by an overview of its geographic distribution and host relationships, including a discussion of human parasitism. Additional sections provide detailed analyses of tick distribution by country and zoogeographic subregion (the Caribbean, southern Mexico and Central America, South America, and the Galápagos Islands), together with a review of the phenomenon of invasive tick species and examination of the many valid and invalid names that have appeared in the Neotropical tick literature. The text concludes with an unprecedented tabulation of all known hosts of Neotropical Ixodidae, including the tick life history stages collected from each host. This book is an invaluable reference for biologists and biomedical personnel seeking to familiarize themselves with the Neotropical tick fauna.
Download or read book Ecological Physiology of Daily Torpor and Hibernation written by Fritz Geiser and published by Springer Nature. This book was released on 2021-08-23 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an in-depth overview on the functional ecology of daily torpor and hibernation in endothermic mammals and birds. The reader is well introduced to the physiology and thermal energetics of endothermy and underlying different types of torpor. Furthermore, evolution of endothermy as well as reproduction and survival strategies of heterothermic animals in a changing environment are discussed. Endothermic mammals and birds can use internal heat production fueled by ingested food to maintain a high body temperature. As food in the wild is not always available, many birds and mammals periodically abandon energetically costly homeothermic thermoregulation and enter an energy-conserving state of torpor, which is the topic of this book. Daily torpor and hibernation (multiday torpor) in these heterothermic endotherms are the most effective means for energy conservation available to endotherms and are characterized by pronounced temporal and controlled reductions in body temperature, energy expenditure, water loss, and other physiological functions. Hibernators express multiday torpor predominately throughout winter, which substantially enhances winter survival. In contrast, daily heterotherms use daily torpor lasting for several hours usually during the rest phase, some throughout the year. Although torpor is still widely considered to be a specific adaptation of a few cold-climate species, it is used by many animals from all climate zones, including the tropics, and is highly diverse with about 25-50% of all mammals, but fewer birds, estimated to use it. While energy conservation during adverse conditions is an important function of torpor, it is also employed to permit or facilitate energy-demanding processes such as reproduction and growth, especially when food supply is limited. Even migrating birds enter torpor to conserve energy for the next stage of migration, whereas bats may use it to deal with heat. Even though many heterothermic species will be challenged by anthropogenic influences such as habitat destruction, introduced species, novel pathogens and specifically global warming, not all are likely to be affected in the same way. In fact it appears that opportunistic heterotherms because of their highly flexible energy requirements, ability to limit foraging and reduce the risk of predation, and often pronounced longevity, may be better equipped to deal with anthropogenic challenges than homeotherms. In contrast strongly seasonal hibernators, especially those restricted to mountain tops, and those that have to deal with new diseases that are difficult to combat at low body temperatures, are likely to be adversely affected. This book addresses researchers and advanced students in Zoology, Ecology and Veterinary Sciences.

Download or read book Studying Vibrational Communication written by Reginald B. Cocroft and published by Springer. This book was released on 2014-07-25 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explains the key ideas, questions and methods involved in studying the hidden world of vibrational communication in animals. The authors dispel the notion that this form of communication is difficult to study and show how vibrational signaling is a key to social interactions in species that live in contact with a substrate, whether it be a grassy lawn, a rippling stream or a tropical forest canopy. This ancient and widespread form of social exchange is also remarkably understudied. A frontier in animal behavior, it offers unparalleled opportunities for discovery and for addressing general questions in communication and social evolution. In addition to reviews of advances made in the study of several animal taxa, this volume also explores topics such as vibrational communication networks, the interaction of acoustic and vibrational communication, the history of the field, the evolution of signal production and reception and establishing a common vocabulary.

Download or read book Bird Migration written by Eberhard Gwinner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: E. GWINNER! The phenomenon of bird migration with its large scale dimensions has attracted the attention of naturalists for centuries. Worldwide billions of birds leave their breeding grounds every autumn to migrate to areas with seasonally more favor able conditions. Many of these migrants travel only over a few hundred kilo meters but others cover distances equivalent to the circumference of the earth. Among these long-distance migrants are several billion birds that invade Africa every autumn from their West and Central Palaearctic breeding areas. In the Americas and in Asia the scope of bird migration is of a similar magnitude. Just as impressive as the numbers of birds are their achievements. They have to cope with the enormous energetic costs of long-distance flying. particularly while crossing oceans and deserts that do not allow replenishment of depleted fat reserves. They have to appropriately time the onset and end of migrations. both on a daily and annual basis. And finally. they have to orient their migratory movements in space to reach their species- or population-specific wintering and breeding grounds, irrespective of the variable climatic conditions along their migratory routes.
