Download or read book Competition and the Structure of Bird Communities MPB 7 Volume 7 written by Martin L. Cody and published by Princeton University Press. This book was released on 2020-03-31 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Professor Cody's monograph emphasizes the role of competition at levels above single species populations, and describes how competition, by way of the niche concept, determines the structure of communities. Communities may be understood in terms of resource gradients, or niche dimensions, along which species become segregated through competitive interactions. Most communities appear to exist in three or four such dimensions. The first three chapters describe the resource gradients (habitat types, foraging sites, food types), show what factors restrict species to certain parts of the resource gradients and so determine niche breadths, and illustrate the important role of resource predictability in niche overlap between species for resources they share. Most examples are drawn from eleven North and South American bird communities, although the concepts and methodology are far more general. Next, the optimality of community structure is tested through parallel and convergent evolution on different continents with similar climates and habitats, and the direct influence of competitors on resource use is investigated by comparisons of species--poor island communities to species-rich mainland ones. Finally, the author discusses those sorts of environments in which the evolution of one species--one resource set is not achieved, and where alternative schemes of resource allocation, often involving several species that act ecologically as one, must be followed.
Download or read book Populations in a Seasonal Environment MPB 5 written by Stephen D. Fretwell and published by Princeton University Press. This book was released on 2020-03-31 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most organisms live in a seasonal environment. During their life cycles, some species face seasons of cold and heat, aridity and abundant rainfall, migration and stable residence, breeding and nonbreeding. Populations grow and decline as supplies of materials essential to their survival wax and wane. Such qualitative truths as these flow obviously from field observations. In this original monograph, Stephen Fretwell analyzes the highly complex interaction between a population and a regularly varying environment in an attempt to define and measure seasonality as a critical parameter in the general theory of population regulation. Concerned primarily with the size and the habitat distribution of populations, Professor Fretwell develops simple models that, when applied to specific populations, usually of birds, demonstrate the effect of seasonal variations on the regulation of populations. He maintains that seasonality, as a concept, is essential to a full understanding of environmental interaction. During the course of his exposition, the author offers several new hypotheses, including theories affecting the breeding, numbers, distribution, and diversity of wintering birds, and a theory affecting the body size of sparrows.
Download or read book Wildlife 2001 Populations written by D.R. McCullough and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1156 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1984, a conference called Wildlife 2000: Modeling habitat relationships of terrestrial vertebrates, was held at Stanford Sierra Camp at Fallen Leaf Lake in the Sierra Nevada Mountains of California. The conference was well-received, and the published volume (Verner, J. , M. L. Morrison, and C. J. Ralph, editors. 1986. Wildlife 2000: modeling habitat relationships of terrestrial vertebrates, University of Wisconsin Press, Madison, Wisconsin, USA) proved to be a landmark publication that received a book award by The Wildlife Society. Wildlife 2001: populations was a followup conference with emphasis on the other major biological field of wildlife conservation and management, populations. It was held on July 29-31, 1991, at the Oakland Airport Hilton Hotel in Oakland, California, in accordance with our intent that this conference have a much stronger international representation than did Wildlife 2000. The goal of the conference was to bring together an international group of specialists to address the state of the art in wildlife population dynamics, and set the agenda for future research and management on the threshold of the 21st century. The mix of specialists included workers in theoretical, as well as practical, aspects of wildlife conservation and management. Three general sessions covered methods, modelling, and conservation of threatened species.
Download or read book Ecology and Management of Cowbirds and Their Hosts written by James N. M. Smith and published by University of Texas Press. This book was released on 2014-09-05 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past two centuries, cowbirds have increased in numbers and extended their range across North America, while many of the native songbird species whose nests they parasitize to raise their young have declined. This timely book collects forty essays by most of the principal authorities on the biology and management of cowbirds. The book's goals are to explore the biology of cowbirds, the threats they pose to host species and populations, and the management programs that are being undertaken to minimize these threats. The book is organized into five sections, each with an extended editors' introduction that places the contributions in a broad, up-to-date setting. The sections cover: The changing abundance of cowbirds and the ways in which their numbers can be estimated. Host choice by cowbirds, the negative effects of cowbirds on particular host species, and the daily patterns of cowbird behavior. Behavioral interactions between cowbirds and specific host species. Patterns of cowbird abundance and host use across varying landscapes. Management programs designed to control cowbirds and protect threatened songbirds.
Download or read book Granivorous Birds in Ecosystems written by Jan Pinowski and published by Cambridge University Press. This book was released on 2012-03-29 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was first published in 1977. It deals with the importance of weed seed and grain-eating birds in natural and agricultural environments. These birds are to be found worldwide and are a component of man-made ecosystems where they are associated with man's main food crops. An analysis is made of their evolution and genetics, population dynamics, energy and food requirements, impact on ecosystems and control. Principles, procedures and basic data are presented that can be applied to the evaluation and control of pest species anywhere in the world. In this synthesis volume full use is made of the systems approach, the ecological and evolutionary aspects of the study are integrated. In linking the studies with fundamental work on bioenergetics, new insights are provided into the behavioural and applied aspects of granivory. Studies which encompass archaeological and anthropological investigations form a backcloth for the detailed interpretation of the population biology and bioenergetics of birds.
Download or read book The Influence of Personality on Dispersal and Population Dynamics in a Passerine Bird written by Stepfanie Maria Aguillon and published by . This book was released on 2014 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dispersal influences the genetic and social composition of populations, yet it has been difficult to understand the mechanisms underlying dispersal and this limits our ability to understand how dispersal may be influencing population dynamics. Behavioral traits, such as aggression, have been implicated as drivers of both dispersal and population dynamics. However, the influence on both has never been addressed in a single system. Western bluebirds (Sialia mexicana) provide an excellent opportunity to address this question, as their dispersal propensity is dependent upon aggressive phenotype and we have detailed observations over a period of more than a decade. I show that natal dispersal is influenced by an interaction between father and son aggressive phenotypes, in addition to available resources on the natal territory. Furthermore, population density is influenced by resource availability and an interaction between population aggression and recruitment of offspring as breeders. Males that breed for multiple seasons once the population has reached saturation recruit a higher proportion of offspring into the population, as do males that are nonaggressive. Males that are nonaggressive are more likely to breed for multiple seasons, which suggests an added cost to aggressive behavior in this species. Both aggressive behavior and the availability of resources are mechanisms influencing dispersal of individuals that manifest at the population scale.

Available in PDF, EPUB and Kindle. Book excerpt: VLADIMIR A. PAYEVSKY PhD DSc (Biology), Honorary member of the American Ornithologists' Union, member of Scientific Program Committees of XXII International Ornithological Congress (1998) and of the Second Meeting of the European Ornithologists Union (1999), was born in Saint-Petersburg, Russia, in 1937. He is currently Chief Research Fellow at the Ornithological Department of the Zoological Institute of the Russian Academy of Sciences, member of the Scientific Council of the Institute, and co-editor-in-chief of the journal "Avian Ecology and Behaviour." Having graduated from the Faculty of Vertebrate Zoology at Petersburg State University in 1961, he began his professional career as a field ornithologist at the Courish Spit, Baltic sea, in the team of zoologists of Biological Station "Rybachy." During more than 35 years the emphasis of his principal scientific interest was in the area of population ecology, breeding biology, and migrations of birds with preferred orientation to demographic aspects of avian life. He has conducted field research mainly in the Baltic, and also during expeditions to Kazakhstan and Tadjikistan. Basic field activities have been the trapping, examination, biometrics, and the ringing of captured birds, as well as the study of avian breeding biology. Vladimir A. Payevsky is an author more than 180 papers and books, including some popular texts.
Download or read book Avian Migration written by Peter Berthold and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological biological observation station in the world (see first chapter "In Memory of Vogelwarte Rossitten"). This area later received enormous impetus when ex perimental research on the subject was begun: the large-scale bird-ringing experiment initiated in Rossitten in 1903 by Johannes Thienemann (who was inspired by the pioneering studies of C. C. M. Mortensen), the experiments on photoperiodicity carried out by William Rowan in the 1920s in Canada and retention and release experiments performed by Thienemann in the 1930s in Rossitten, the first experimental study on the orientation of migratory birds. After the Second World War, migration research, while continuing in the previous areas, also expanded into new directions such as radar ornithology, ecophysiology and hormonal control mechanisms, studies of evolution, ge netics, telemetry and others.

Available in PDF, EPUB and Kindle. Book excerpt: There are more than one thousand species of threatened birds in the world, while many others are valued for sport and some are serious pests. This volume reviews our current understanding of avian population dynamics and explores ways in which population studies can contribute to effective conservation and management. Estimation of demographic parameters, the role of mathematical modelling, and the special problems of island populations and seabird populations are discussed. The emphasis throughout is on how bird populations are regulated under various constraints and conditions, including the impact of environmental changes.
