Download or read book Tropical Rain Forest Ecosystems written by H. Lieth and published by Elsevier. This book was released on 2012-12-02 with total page 733 pages. Available in PDF, EPUB and Kindle. Book excerpt: After publication of the first volume of the Tropical Rain Forest, the International Journal of Mycology and Lichenology commented ``This is a welcome addition to the literature on the ecology of tropical rain forests. The book provides a wealth of data and stimulating discussions and is of great interest to ecologists interested in tropical areas.'' Whereas the first volume dealt with system-ecological aspects such as community organization and processes, the present volume concentrates on biogeographical aspects such as species composition, diversity, and geographical variation.Recent ecological research in the tropical rain forest has greatly extended our understanding of biogeographical patterns of variation in the various groups of organisms, and has revealed many of the ecological and evolutionary forces that led to the present patterns of variation. Many important systems of co-evolution between the tropical rain forest ecosystems have also come to light, and the loss of species and related damage is better understood in quantitative terms.This volume presents a comprehensive review of these and other features of the rain forest ecosystem structure, and the ecological processes operating that system. General chapters on abiotic and biotic factors are followed by specific chapters on all major groups of organisms. Prospects for the future are discussed and research needs clearly stated. Also the human exploitation of the system, its effects and its limits are discussed. The book is extensively illustrated by photographs, graphs, and tables, and comprehensive bibliographies follow each chapter. Author, systematic and subject indices complete the book.It is a must for all ecologists, agriculturists, foresters, agronomists, hydrologists, soil scientists, entomologists, human ecologists, nature conservationists, and planners dealing with tropical areas. Biologists and environmentalists will also find the volume of great interest.

Book excerpt: Necrophilous insects occupy a biologically interesting ecological niche because carrion is a highly desirable but ephemeral food source. Insects that feed on carrion are widely studied in forensic and entomological disciplines, but many taxa attracted to decomposition are often overlooked. Dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae and Aphodiinae) are frequently found at carrion, but very little is known about their attraction to this resource. Are dung beetles attracted to the carrion itself or are they attracted indirectly because the gastrointestinal contents of the animals are exposed? This research attempts to disentangle the association between dung beetles and carrion by examining the distribution of dung beetles on the head- and tail-end of rat carrion, delimiting a resource more attractive to necrophagous insects (head-end) and a resource more attractive to coprophagous insects (tail-end). Comparisons were made between dung beetle distributions on rat carrion with carrion beetle (Coleoptera: Silphidae) distributions, a model of distribution patterns for a taxon known to target carrion. A total of 25,081 dung beetle individuals from 21 species and 3,333 individual carrion beetles from 9 species were collected in our year-long study. Results indicate that dung beetles show higher attraction to the head-end of rat carrion than the tail-end. This distribution pattern is also found in carrion beetles, suggesting that similar resources are being targeted. When dung beetles are grouped by behavioral guilds, rollers and tunnellers also share this pattern of greater abundance at the head-end rather than the tail-end, but dwellers show no discernable difference between the head- and tail-end. This research indicates that dung beetle interactions with carrion that are more complex than previously understood. Our results suggest that scarabaeine dung beetles target carrion preferentially, challenging the long-held belief that, within temperate regions, dung beetle necrophagy is rare and unimportant to the decomposition of carrion.

Download or read book Living with the Flood written by Samantha Paul and published by Oxbow Books. This book was released on 2015-11-30 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The site at Mill Lane, Sawston, represents millennia of human activity within a dynamic and changing landscape setting. River valleys have been a focus for human activity since the early Holocene and, in addition to providing abundant archaeological evidence for this activity, the proximity to water also highlights the potential for the preservation of both archaeological remains and palaeoenvironmental source material. However, human activity within river valleys also commonly bridges areas of both wetland and dryland; ecological zones which are often approached using quite different archaeological methods and which present considerable differences in levels of archaeological visibility and preservation. The site at Mill Lane offered an uncommon opportunity to explore the interface between these two types of environment. Here we present the results of the study of a wetland/dryland interface on the edge of palaeochannels of the River Cam in Cambridgeshire. Through the integrated archaeological and palaeoenvironmental analysis of a site on the western edge of Sawston, a detailed picture of life on the edge of the floodplain from the late glacial to the post-medieval periods has been developed. At the heart of this is the relationship between people and their changing environment, which reveals a shifting pattern of ritual, occupation and more transitory activity as the riparian landscape in a wooded setting became a wetland within a more openly grazed environment. The presence of potential built structures dating to the early Neolithic, the early Bronze Age and the early Anglo-Saxon periods provides some sense of continuity, although the nature of these structures and the environmental context within which they were constructed was very different.

Download or read book Dung Beetle Ecology written by Ilkka Hanski and published by Princeton University Press. This book was released on 2014-07-14 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many ecosystems dung beetles play a crucial role--both ecologically and economically--in the decomposition of large herbivore dung. Their activities provide scientists with an excellent opportunity to explore biological community dynamics. This collection of essays offers a concise account of the population and community ecology of dung beetles worldwide, with an emphasis on comparisons between arctic, temperate, and tropical species assemblages. Useful insights arise from relating the vast differences in species' life histories to their population and community-level consequences. The authors also discuss changes in dung beetle faunas due to human-caused habitat alteration and examine the possible effects of introducing dung beetles to cattle-breeding areas that lack efficient native species. "With the expansion of cattle breeding areas, the ecology of dung beetles is a subject of great economic concern as well as one of intense theoretical interest. This excellent book represents an up-to-date ecological study covering important aspects of the dung beetle never before presented."--Gonzalo Halffter, Instituto de Ecologia, Mexico City Originally published in 1991.

Download or read book Floral Mimicry written by Steven D. Johnson and published by Oxford University Press. This book was released on 2016-11-03 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mimicry is a classic example of adaptation through natural selection. The traditional focus of mimicry research has been on defence in animals, but there is now also a highly-developed and rapidly-growing body of research on floral mimicry in plants. This has coincided with a revolution in genomic tools, making it possible to explore which genetic and developmental processes underlie the sometimes astonishing changes that give rise to floral mimicry. Being literally rooted to one spot, plants have to cajole animals into acting as couriers for their pollen. Floral mimicry encompasses a set of evolutionary strategies whereby plants imitate the food sources, oviposition sites, or mating partners of animals in order to exploit them as pollinators. This first definitive book on floral mimicry discusses the functions of visual, olfactory, and tactile signals, integrating them into a broader theory of organismal mimicry that will help guide future research in the field. It addresses the fundamental question of whether the evolutionary and ecological principles that were developed for protective mimicry in animals can also be applied to floral mimicry in plants. The book also deals with the functions of floral rewardlessness, a condition which often serves as a precursor to the evolution of mimicry in plant lineages. The authors pay particular attention to the increasing body of research on chemical cues: their molecular basis, their role in cognitive misclassification of flowers by pollinators, and their implications for plant speciation. Comprehensive in scope and conceptual in focus, Floral Mimicry is primarily aimed at senior undergraduates, graduate students, and researchers in plant science and evolutionary biology.

Download or read book Dance of the Dung Beetles written by Marcus Byrne and published by Wits University Press. This book was released on 2019-04-01 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sweeping scientific and social history of the humble dung beetle The humble and industrious dung beetle is a marvelous beast: the 6,000 species identified so far are intricately entwined with human history and scientific endeavor. These night-soil collectors of the planet have been worshipped as gods, worn as jewelry, and painted by artists. More practically, they saved Hawaii from ecological blight, and rescued Australia from plagues of flies. They fertilize soil, cleanse pastures, steer by the stars, and have a unique relationship with the African elephant (along with many other ungulates). Above all, they are the ideal subject for biological study in an evolving world. In this sweeping history of more than 3,000 years, beginning with Ancient Egypt, scientist Marcus Byrne and writer Helen Lunn capture the diversity of dung beetles and their unique behavior patterns. Dung beetles’ fortunes have followed the shifts from a world dominated by a religion that symbolically incorporated them into some of its key concepts of rebirth, to a world in which science has largely separated itself from religion and alchemy. With over 6,000 species found throughout the world, these unassuming but remarkable creatures are fundamental to some of humanity’s most cherished beliefs and have been ever present in religion, art, literature, science and the environment. They are at the center of current gene research, play an important role in keeping our planet healthy, and some nocturnal dung beetles have been found to navigate by the starry skies. Outlining the development of science from the point of view of the humble dung beetle is what makes this charming story of immense interest to general readers and entomologists alike.

Available in PDF, EPUB and Kindle. Book excerpt: THE ECOLOGICAL SURVEY on which this book is based began to be planned in 1942, and since 1945 has been mainly centred upon Oxford University's estate at Wytham Woods, where a rich series of habitats from open ground and limestone to woodland with many springs and marshes interspersed occupies a hill set in riverine surroundings. Here biological research workers from the University have accumulated a considerable body of knowledge, some of which I have arranged in a general setting that allows one to comprehend some of the inter-related parts of the whole system. It is also intended to provide a framework for understanding animal communities elsewhere. The ecological inquirer is, more than most scien tific people, apt to fmd himself lost in a large labyrinth of interrelations and variables. The dictionary defmes a labyrinth as 'an intricate structure of inter communicating passages, through which it is difficult to fmd one's way without a clue'. This could equally be a figurative description of plant and animal communi ties. The present book seeks to provide a plan of construction of the labyrinth and a few new clues that may help the inquirer to know where he is on the gene ral ecological map. In presenting this blue-print of animal communities I have avoided giving long lists of species such as the botanist, with his smaller kingdom, can handle fairly well.

Download or read book Biology of Rove Beetles Staphylinidae written by Oliver Betz and published by Springer. This book was released on 2018-05-15 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rove beetles (Staphylinidae) are common elements of the soil biota, living in the litter and deeper soil layers. Although they are one of the most diverse and speciose groups of insects, no comprehensive books on their general evolution and ecology are as yet available. This book fills that gap, discussing significant aspects and active research examples in the fields of phylogeny and systematics, ecology and conservation, and reproduction and development. The combination of review chapters and case studies provides an excellent introduction to the biology of rove beetles and enables readers to become familiar with active research fields in this megadiverse group of beetles. Offering easy access to these fields, it also demonstrates how staphylinids are used as bioindicators in applied ecosystem research, including that concerning conservation issues. Experienced scientists and beginners alike find the diversity of subjects covered intriguing and inspiring for continuing and starting their own research. The book is intended for students and researchers in biology and zoology (entomology), including morphologists, ecologists, soil scientists, evolutionary biologists, paleontologists, biogeographers, taxonomists and systematists.
