Book Synopsis The Social Structure of an Avian Community During the Nonbreeding Season by : Wendy K. Gram
Download or read book The Social Structure of an Avian Community During the Nonbreeding Season written by Wendy K. Gram and published by . This book was released on 1996 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the breeding season, many bird species move to different habitats or alter their social behavior for the nonbreeding season. High densities of neotropical migrant species funnel into Mexico, Central America, and the West Indies, but relatively little is known about the wintering strategies of these migrants or the permanent resident species. I documented the distribution of migrant species in four habitats in the El Cielo Biosphere Reserve in southern Tamaulipas, Mexico, and studied the structure of mixed-species flocks which consisted of both migrant and Mexican resident species. I used point count surveys and mist nets to determine the distribution of migrant species among tropical semi-deciduous forest (300 m altitude), cloud forest (1100 m altitude), humid oak-pine forest (1200 m altitude), and dry pine-oak forest (1800 m altitude) in the Sierra Madre Oriental mountains. Forty-one species of migrants and 136 species of Mexican residents were observed during the winters of 1993-1995; migrant species represented from 22% to 29% of the species detected in point counts and captured in mist nets. Habitats at higher elevations with temperate-like forests and at lower elevations with tropical forests supported the greatest number and highest abundance of migrant species. Migrants showed some flexibility in habitat use, particularly compared to resident species. Mixed-species flocks, particularly insectivorous foraging flocks, were prevalent during the nonbreeding season in northern Mexico. Flocks in the dry pine-oak forest averaged the most individuals and species per flock. Participants in mixed-species flocks did not appear to be a random collection of species, and niche partitioning by foraging behavior was ubiquitous among flock members. Ruby-crowned kinglet, a migrant species, and crescent-chested warbler, a Mexican resident species, were nuclear flock species in one habitat and follower flock species in another habitat; their foraging behavior also changed among habitats and with different flockmates. Patterns of foraging behavior in mixed-species flocks were consistent with models of competition and habitat selection, but I could not separate the effects of these processes in this system. Survival during the nonbreeding season is critical in maintaining populations; continued studies of winter community structure are important for understanding large-scale population dynamics.
Book Synopsis Forest Structure, Function and Dynamics in Western Amazonia by : Randall W. Myster
Download or read book Forest Structure, Function and Dynamics in Western Amazonia written by Randall W. Myster and published by John Wiley & Sons. This book was released on 2017-01-03 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Amazon Basin contains the largest and most diverse tropical rainforest in the world. Besides the Andes and the Atlantic Ocean, the rainforest is bounded to the north by the Guiana crystalline shield and to the south by the Brazilian crystalline shield, marked at their edges by cataracts in the rivers and often dominated by grasslands. This book is motivated not just by the Amazon's scientific interest but also by its role in many ecosystem functions critical to life on Earth. These ecosystems are characterized both by their complexity and their interactive, higher-order linkages among both abiotic and biotic components. Within Amazonia, the Western Amazon (west of 65° latitude) is the most pristine and, perhaps, the most complex within the Amazon Basin. This Western Amazon may be broadly divided into non-flooded forests (e.g. terra firme, white sand, palm) and forests flooded with white water (generally referred to as várzea) and with black water (generally referred to as igapó). Here, for the first time, is a book devoted entirely to Western Amazonia, containing chapters by scientists at the forefront of their own areas of expertise. It should be a valuable resource for all future researchers and scholars who venture into Western Amazonia, as it continues to be one of the most beautiful, mysterious, remote and important ecosystems on Earth.

Book Synopsis Conservation of Tropical Birds by : Navjot S. Sodhi
Download or read book Conservation of Tropical Birds written by Navjot S. Sodhi and published by John Wiley & Sons. This book was released on 2011-02-23 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation of Tropical Birds has been written by four conservation biologists whose expertise spans all the tropical regions of the world. It is the first book to cover all the major issues in tropical bird conservation. Current problems faced by tropical bird conservationists are summarised and potential solutions outlined based on the results of case studies. Birds are key indicators of ecosystem health, and such a well-studied group of organisms, that they provide an excellent lens through which to examine global conservation problems caused by phenomena such as climate change, declines in ecosystem services, habitat loss, fires, overexploitation, and invasive species. Therefore, the book also provides an engaging synopsis of the general issues in conservation and the problems faced by other wildlife. This book serves as an important resource and companion to all people interested in observing and conserving birds in the tropics and elsewhere.
Download or read book Life After Logging written by E. Meijaard and published by CIFOR. This book was released on 2005-01-01 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a technical review of ecological and life history information on a range of Bornean wildlife species, aimed at identifying what makes these species sensitive to timber harvesting practices and associated impacts. It addresses three audiences: 1) those involved in assessing and regulating timber harvesting activities in Southeast Asia, 2) those involved in trying to achieve conservation goals in the region, and 3) those undertaking research to improve multipurpose forest management. This book shows that forest management can be improved in many simple ways to allow timber extraction and wildlife conservation to be more compatible than under current practices. The recommendations can also be valuable to the many governmental and non-governmental organisations promoting sustainable forest management and eco-labelling. Finally, it identifies a number of shortcomings and gaps in knowledge, which the hope can interest the scientific community and promote further research. This review is, an important scientific step toward understanding and improving sustainable forestry practices for long-term biodiversity conservation. Even in the short term, however, significant improvements can be made to improve both conservation and the efficiency of forest management, and there is no need to delay action due to a perceived lack of information. In the longer term it is expected that the recommendations from this review will be implemented, and that further research will continue to help foster an acceptable balance among the choices needed to maintain healthy wildlife populations and biodiversity in a productive forest estate.

Book Synopsis Mixed-Species Groups of Animals by : Eben Goodale
Download or read book Mixed-Species Groups of Animals written by Eben Goodale and published by Academic Press. This book was released on 2017-04-26 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixed-Species Groups of Animals: Behavior, Community Structure, and Conservation presents a comprehensive discussion on the mixed-species groups of animals, a spectacular and accessible example of the complexity of species interactions. They are found in a wide range of animals, including invertebrates, fish, mammals and birds, and in different habitats, both terrestrial and aquatic, throughout the world. While there are more than 500 articles on this subject scattered in separate categories of journals, there has yet to be a general, cross-taxa book-length introduction to this subject that summarizes the behavior and community structure of these groups. The authors first survey the diversity of spatial associations among animals and then concentrate on moving groups. They review the major classes of theories that have been developed to explain their presence, particularly in how groups increase foraging efficiency and decrease predation. Finally, they explore the intricacies of species interactions, such as communication, that explain species roles in groups and discuss what implications these social systems have for conservation. Functions as a single resource for readers inside and outside of academia on mixed-species groups, serving as a foundation for future research in this field Begins with an empirical summary of mixed-species distribution and reviews how the theories explaining their adaptive benefits are supported by the evidence Includes many aspects of mixed-group behavior (e.g. foraging, communication, collective decision-making, dominance, social roles of species and leadership, relationship to conservation) that were not previously or easily accessible
Book Synopsis Ecology and Evolution of Cooperative Breeding in Birds by : Walter D. Koenig
Download or read book Ecology and Evolution of Cooperative Breeding in Birds written by Walter D. Koenig and published by Cambridge University Press. This book was released on 2004-04-22 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cooperative breeders are species in which more than a pair of individuals assist in the production of young. Cooperative breeding is found in only a few hundred bird species world-wide, and understanding this often strikingly altruistic behaviour has remained an important challenge in behavioural ecology for over 30 years. This book highlights the theoretical, empirical and technical advances that have taken place in the field of cooperative breeding research since the publication of the seminal work Cooperative Breeding in Birds: Long-term Studies of Behavior and Ecology (1990, HB ISBN 0521 372984, PB ISBN 0521 378907). Organized conceptually, special attention is given to ways in which cooperative breeders have proved fertile subjects for testing modern advances to classic evolutionary problems including those of sexual selection, sex-ratio manipulation, life-history evolution, partitioning of reproduction and incest avoidance. It will be of interest to both students and researchers interested in behaviour and ecology.
Book Synopsis Nomadic Desert Birds by : W. Richard J. Dean
Download or read book Nomadic Desert Birds written by W. Richard J. Dean and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: My interest in the behaviour and movements of birds of arid and semi-arid ecosystems began when my wife, Sue Milton, and I were Roy Siegfried, Director, at that time, of the Percy approached by Prof. FitzPatrick Institute of African Ornithology, to set up a project to investigate granivory in the South African Karoo. Sue and I spent some time finding a suitable study site, setting up accommodations and an automatic weather station at Tierberg, in the southern Karoo near the village of Prince Albert, and planning projects. Among our first projects was a transect where we noted plant phe nology, measured seed densities on the soil surface, counted birds, observed ant activity, measured soil surface temperatures and col lected whatever climate data we could at 40 sites along a 200-km oval route. Along the way, we became interested in the marked presence and absence of birds at certain sites - abundant birds one day, and very few birds at the same site a month later. Subsequent counts along fixed transects through shrublands confirmed that a number of bird species were highly nomadic over short and long distances, locally and regionally, leading to speculation on how widespread these movements were in the arid ecosystems of the world.
Book Synopsis Current Ornithology Volume 17 by : Charles F. Thompson
Download or read book Current Ornithology Volume 17 written by Charles F. Thompson and published by Springer Science & Business Media. This book was released on 2010-09-09 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.
Download or read book Living on the Edge written by Le Zwarts and published by BRILL. This book was released on 2012-01-01 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Living on the Edge' examines the function of the Sahel region of Africa as an important wintering area for long-distance migrant birds. It describes the challenges the birds have to cope with – climate change, of course, and rapid man-made habitat changes related to deforestation, irrigation and reclamation of wetlands. How have all these changes affected the birds, and have birds adapted to these changes? Can we explain the changing numbers of breeding birds in Europe by changes in the Sahel, or vice versa?

Book Synopsis Ecology and Behavior of Chickadees and Titmice by : Ken A. Otter
Download or read book Ecology and Behavior of Chickadees and Titmice written by Ken A. Otter and published by Oxford University Press. This book was released on 2007-02 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Members of the Paridae family represent popular organisms for ornithological research. This is due to the flexibility to study this group of birds in both the lab and the natural environment. In contrast to previously published literature, this volume concentrates on research themes. The editor has invited a team of leading specialists to provide a synopsis of ecological and behavioural research, and to compare and contrast this with what is known from Old World members of this family (e.g. blue tit and great tit) as well as other avian groups.
