Download or read book Global Warming and Population Responses among Great Plains Birds written by Paul Johnsgard and published by Lulu.com. This book was released on 2015-02-19 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Based on an analysis of 47 years (1967-2014) of Audubon Christmas Bird Counts (CBC), evidence for population changes and shifts in early winter (late December) ranges of nearly 150 species of birds in the Great Plains states is summarized, a region defined as including the Dakotas, Nebraska, Kansas, Oklahoma, and the Texas panhandle. The rationale for this study had its origins in Terry Root's 1988 Atlas of North American Wintering Birds. ... The present analysis includes all of the 40 annual CBC surveys from the 1967-8 to the 2006-7 counts, plus the results of the most recent 2013-14 CBC. The present summary quantitatively describes the early winter abundance for 147 of the most commonly encountered regional species, illustrating their temporal changes in geographic distributions and relative abundance between 1967 and 2014"--Publisher description.
Download or read book Effects of Climate Change on Birds written by Anders Pape Møller and published by OUP Oxford. This book was released on 2010-08-12 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change affects all living organisms; it has done so in the past and will do so in the future. However, current climate change is exceptional both in terms of the rate of change and the impact of multiple types of global change on individuals, populations, species, and ecosystems. Effects of Climate Change on Birds provides an exhaustive and up-to-date synthesis of the science of climate change as it relates to birds. Compared with any other class of animals, birds provide more long-term data and extensive time series (some dating back more than 100 years), a more geographically and taxonomically diverse source of information, and a longer tradition of extensive research. In fact this research record exceeds what is available in all other organisms combined.
Download or read book At Home and at Large in the Great Plains Essays and Memories written by Paul Johnsgard and published by Lulu.com. This book was released on 2015 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: These fourteen essays originally appeared in Prairie Fire, a monthly newspaper that for seven years has carried important messages of social, environmental, and economic issues to residents of Nebraska, Iowa, Colorado, and South Dakota, and subscribers in the rest of the world. They discuss the North American east-west ecological boundaries, spring migration events, bird feeders, feathered survivors of a glacial past, the threatened sharp-tailed grouse, the effects of climate change, some "sacred places"-Aransas National Wildlife Refuge, the Ashfall Fossil Beds, Squaw Creek Refuge, the Hutton Niobrara Ranch Sanctuary, and Yellowstone National Park-, our troubles with mountain lions and grizzly bears, and crane season in Wyoming. There is also an expanded informal autobiography, "My Life in Biology" and a current and comprehensive list of all publications of a writer described as "probably the world's most prolific living author of ornithological and natural history literature."
Download or read book Birds and Climate Change written by James W. Pearce-Higgins and published by Cambridge University Press. This book was released on 2014-06-12 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the red grouse to the Ethiopian bush-crow, bird populations around the world can provide us with vital insights into the effects of climate change on species and ecosystems. They are among the best studied and monitored of organisms, yet many are already under threat of extinction as a result of habitat loss, overexploitation and pollution. Providing a single source of information for students, scientists, practitioners and policy-makers, this book begins with a critical review of the existing impacts of climate change on birds, including changes in the timing of migration and breeding and effects on bird populations around the world. The second part considers how conservationists can assess potential future impacts, quantifying how extinction risk is linked to the magnitude of global change and synthesising the evidence in support of likely conservation responses. The final chapters assess the threats posed by efforts to reduce the magnitude of climate change.

Download or read book The North American Swans Their Biology and Conservation written by Paul Johnsgard and published by Lulu.com. This book was released on 2020-03-23 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among birds, swans are relatively long-lived species and are also among the most strongly monogamous, having prolonged pair and family bonds that strongly influence their reproductive and general social behavior, which, in combination with their beauty and elegance, contribute to the overall high degree of worldwide human interest in them. This volume of more than 59,000 words describes the distributions, ecology, social behavior, and breeding biologies of the four species of swans that breed or have historically bred in North America, including the native trumpeter and tundra swans, the introduced mute swan, and the marginally occurring whooper swan. Also included are 5 distribution maps, 15 drawings, 27 photographs by the author, and a reference section of nearly 1,000 literature citations.
Download or read book The North American Perching and Dabbling Ducks written by Paul Johnsgard and published by Lulu.com. This book was released on 2017-03 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, the fourth in a series of books that collectively update and expand P.A. Johnsgard's 1975 The Waterfowl of North America, summarizes research findings on this economically and ecologically important group of waterfowl. The volume includes the mostly tropical perching duck tribe Cairinini, of which two species, the muscovy duck and the wood duck, are representatives. Both species are adapted for foraging on the water surface, mostly on plant materials, but typically perch in trees and nest in elevated tree cavities or other elevated recesses. This volume also includes the dabbling, or surface-feeding, duck tribe Anatini, a large assemblage of duck species that mainly forage on the water surface but nest on the ground, or only very rarely in elevated locations. Of this tribe, 12 species that regularly breed in North America are included, among them such familiar species as mallards, wigeons, pintails, and teal. Descriptive accounts of the distributions, populations, ecologies, social-sexual behaviors, and breeding biology of all these species are provided, together with distribution maps. Five additional Eurasian and West Indian species have been reported several times in North America; these have been included with more abbreviated accounts, but all 17 species are illustrated by drawings, photographs, or both. The text includes about 84,000 words and contains more than 1,000 references. There are also 12 distribution maps, 21 drawings, 28 photographic plates, and 58 anatomical or behavioral sketches.
Download or read book The North American Geese written by Paul Johnsgard and published by Lulu.com. This book was released on 2016-08-23 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: The eight currently recognized species of North American geese are part of a familiar group of birds collectively called waterfowl, all of which are smaller than swans and generally larger than ducks. They include the most popular of our aquatic gamebirds, with several million shot each year by sport hunters. Our two most abundant waterfowl, the Canada goose and snow goose, have populations collectively totaling about 15 million individuals. Like swans, the lifelong pairbonding of geese, their familial care, and prolonged social attachment to their offspring are legendary. Their seasonal migratory flights sometimes span thousands of miles, and the sight of their long, wavering flight formations are as much the symbols of seasonal change as are the spring songs of cardinals or the appearance of autumnal leaf colors. This book describes each species' geographic range and subspecies, its identification traits, weights and measurements, and criteria for its age and sex determination. Ecological and behavioral information includes each species' breeding and wintering habitats, its foods and foraging behavior, its local and long distance movements, and its relationships with other species. Reproductive information includes each species' age of maturity, pair-bond pattern, pair-forming behaviors, usual clutch sizes and incubation periods, brooding behavior, and postbreeding behavior. Mortality sources and rates of egg, young, and adult losses are also summarized, and each species' past and current North American populations are estimated. In addition to a text of nearly 60,000 words, the book includes 8 maps, 21 line drawings, and 28 photographs by the author, as well as more than 700 literature citations.
Download or read book The Birds of Nebraska written by Paul Johnsgard and published by Lulu.com. This book was released on 2018-07-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This annotated list of the birds of Nebraska grew gradually out of research associated with my writing of the Birds of the Great Plains: Breeding Species and Their Distribution (Johnsgard, 1979a). It expands and updates an earlier version that was published in 2013 by the University of Nebraska–Lincoln Libraries DigitalCommons’ Zea Books (Johnsgard, 2013a). It has been updated and modified in its current revision to conform with the most recent (2017) major revision of the American Ornithologists’ Society’s Checklist of North American Birds (Chesser et al., 2017). It has also been modified in its current revision to conform very closely to the most recent “Official List of the Birds of Nebraska” by the Nebraska Ornithologists’ Union (Gubanyi, 1997, and later supplements in the Nebraska Bird Review, to 84:138–150). The NOU’s official state list of birds (461 species as of 2017) is based on actual specimen evidence or some other convincing basis of each species’ proven occurrence in the state. That list includes 337 “regular” species, 29 “casual” species, 90 “accidental” species, and 5 extinct or extirpated species. In this edition I have classified 368 of the 461 species of Nebraska birds as ranging in relative frequency of occurrence as “abundant” to “rare.” There are also 61 species considered to be of “accidental” occurrence, having been reliably reported in Nebraska no more than five times, 20 that are considered “extremely rare” or “very rare,” if reported from six to 25 times. There are also three extinct, four extirpated, and five unsuccessfully introduced species. Thirteen hypothetical species of dubious origin or identification are mentioned parenthetically. The text includes more than 123,000 words, nearly 200 literature references, and 19 pages of drawings and maps.

Download or read book Behavioural and Ecological Consequences of Urban Life in Birds written by Caroline Isaksson and published by Frontiers Media SA. This book was released on 2018-06-19 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urbanization is next to global warming the largest threat to biodiversity. Indeed, it is becoming increasingly evident that many bird species get locally extinct as a result of urban development. However, many bird species benefit from urbanization, especially through the abundance of human-provided resources, and increase in abundance and densities. These birds are intriguing to study in relation to its resilience and adaption to urban environments, but also in relation to its susceptibility and the potential costs of urban life. This Research Topic consisting of 30 articles (one review, two meta-analyzes and 27 original data papers) provides insights into species and population responses to urbanization through diverse lenses, including biogeography, community ecology, behaviour, life history evolution, and physiology.

Download or read book The North American Whistling Ducks Pochards and Stifftails written by Paul Johnsgard and published by Lulu.com. This book was released on 2017-03-24 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the 12 species representing three waterfowl tribes described in this volume are not closely related, they fortuitously provide an instructive example of adaptive evolutionary radiation within the much larger waterfowl lineage (the family Anatidae), especially as to their divergent morphologies, life histories, and social behaviors. The whistling-ducks (Dendrocygna), with three known North American species, are notable for their permanent pair-bonds, extended biparental family care, and strong social cohesion. In contrast, males of the five typical pochards of North American diving ducks (Aythya) establish monogamous pair-bonds that are maintained only long enough to assure that the female's eggs are fertilized. The endpoint of this behavioral gradient, promiscuity or polygyny, exists among at least some of the typical stifftails (Oxyura). Such diverse reproductive strategies have exerted powerful evolutionary influences on interspecies variations in sexual dimorphism, sexual behavior, anatomy, ecology, and other traits. This volume includes more than 63,000 words, plus some 200 maps, photos, drawings, and sketches, and nearly 650 literature citations. It is the last of five volumes that describe all 55 waterfowl species that have been historically documented in North America; collectively, the volumes total over 300,000 words, with nearly 3,000 literature citations, and more than 600 maps, photos, drawings, and sketches.

Available in PDF, EPUB and Kindle. Book excerpt: This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel's, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly popular with naturalists, birders, and other outdoor enthusiasts.
