Available in PDF, EPUB and Kindle. Book excerpt: International Review of Forestry Research, Volume 1 is a collection of reviews and summaries of world literature concerning defined problem areas in forestry research. This book is composed of seven chapters, and starts with a general survey of the historical development of international forestry research, specifically in Central Europe, since the origin of forest management and of forestry as a science lies on it. This historical development includes historical methods in the practice of forest science, human influences, economics, culture, and laws. The subsequent chapters describe the methods for improvement of forest growth on swamps, the concept of nutrient requirement in forestry, and the methods for determining nutrient requirements of forest trees and stands. These topics are followed by discussions on the biological and environmental aspects of forest site appraisal systems; the anatomy, chemistry, and physiology of bark; and advances in the physiology and biochemistry of tree seeds during maturation, storage, and germination. The concluding chapter considers the development of harmonious control in agricultural, horticultural, and forestry crops, as well as the human influence on regulation and determination of insect populations. This book will prove useful to forest scientists, research workers, teachers, advanced students, administrators, economists, and forest and land managers.

This book was released on 2013-06-29 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects multiply. Destruction reigns. There is dismay, followed by outcry, and demands to Authority. Authority remembers its experts or appoints some: they ought to know. The experts advise a Cure. The Cure can be almost anything: holy water from Mecca, a Government Commis sion, a culture of bacteria, poison, prayers denunciatory or tactful, a new god, a trap, a Pied Piper. The Cures have only one thing in common: with a little patience they always work. They have never been known entirely to fail. Likewise they have never been known to prevent the next outbreak. For the cycle of abundance and scarcity has a rhythm of its own, and the Cures are applied just when the plague of insects is going to abate through its own loss of momentum. -Abridged, with insects in place of voles, from C. Elton, 1924, Voles, Mice and Lemmings, with permission of Oxford University Press This book is an enquiry into the "natural rhythms" of insect abundance in forested ecosystems and into the forces that give rise to these rhythms. Forests form unique environ ments for such studies because one can find them growing under relatively natural (pri meval) conditions as well as under the domination of human actions. Also, the slow growth and turnover rates of forested ecosystems enable us to investigate insect popula tion dynamics in a plant environment that remains relatively constant or changes only slowly, this in contrast to agricultural systems, where change is often drastic and frequent.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehenisive text approaches the subject from an ecological/evolutionary biological perspective. The assumption is that one cannot study forest insects without understanding the dynamics of the relationship between an insect and its host plant. This relationship includes knowing what factors control forest insect populations such as food, food quality, tree vigor, host selection, and symbiotic relationships. The authors also discuss tree-injuring insects from the perspective of their influence on tree physiology and growth as well as economic and commercial effects. The book represents a "modern" approach to the topic of forest and shade tree insects; is well-illustrated; and includes a comprehensive primary reference list.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past three decades there has been a dramatic increase in theoretical and practical studies on insect natural enemies. The appeal of insect predators, and parasitoids in particular, as research animals derives from the relative ease with which many species may be cultured and experimented with in the laboratory, the simple life cycles of most parasitoids, and the increasing demand for biological pest control. There is now a massive literature on insect natural enemies, so there is a great need for a general text that the enquiring student or research worker can use in deciding on approaches and techniques that are appropriate to the study and evaluation of such insects. This book fulfils that demand. A considerably updated and expanded version of a previous best-seller, it is an account of major aspects of the biology of predators and parasitoids, punctuated with information and advice on which experiments or observations to conduct, and how to carry them out. Guidance is provided, where necessary, on the literature that may need to be consulted on particular topics. While researchers can now refer to several books on parasitoids and predators, Insects as Natural Enemies is unique in emphasising practicalities. It is aimed at students and professional working in universities and both government and commercial institutes in the fields of pest management, agriculture, horticulture and forestry.

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 Jervis's Insects as Natural Enemies: Practical Perspectives written by Ian C.W. Hardy and published by Springer Nature. This book was released on 2023-12-11 with total page 779 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a dramatic increase in theoretical and practical studies on insect natural enemies over the last decades. The appeal of insect predators and, in particular, parasitoids, as research animals derives from the relative ease with which many species may be cultured and experimented on in the laboratory, the simple life-cycles of most parasitoid species, and the increasing demand for biological pest control as a key component of the integrated pest management approach. There is now a very substantial literature on insect natural enemies and thus a great need for a general text that enquiring students or research workers can use in deciding on approaches and techniques that are appropriate to the study and evaluation of such insects. This book fulfils that demand. It is a considerably updated and expanded version of a previous best-seller and provides an account of major aspects of the biology of predators and parasitoids, punctuated with information and advice on which experiments or observations to conduct and, importantly, how to carry them out. Guidance is provided, where necessary, on the most recent further literature that may need to be consulted on given topics. While researchers can now refer to several books on parasitoids and predators, Jervis’s Insects as Natural Enemies is unique in emphasising practicalities. It is aimed at students and professionals working in universities and both government and commercial institutes in the fields of integrated pest management, agriculture, horticulture and forestry, as well as those interested in fundamentals of behavioural, population, community and evolutionary ecology.

Book excerpt: Avian Biology is a collection of papers that deals with biological aspects of birds such as their classification and habitat behavior. One paper reviews how birds are classified through practical systematics, study of fossils, and some of the problems encountered in the arrangement of major groups. Another paper discusses the origin and evolution of birds from their reptilian predecessors to their current evolutionary rates. Evolutionary rates vary depending on access to new habitats; if the environment is static, evolutionary rates can also slow down. One author discusses the inter-relations of sea birds with their marine environment, including coastal areas and the biological properties of the surface water. Another author describes the biology of desert birds relating to nomadism behavior and physical adaptations especially to the arid environment. The author also describes the cooling mechanism of these desert birds. Another paper evaluates the ecological aspect of behavior that includes foraging, habitat selection, mating, and flocking cohesion. Avian biologists, zoologists, and readers who have a general interest in birds will find this book useful.

Download or read book Avoiding Attack written by Graeme D. Ruxton and published by Oxford University Press. This book was released on 2019-01-31 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Avoiding Attack discusses the diversity of mechanisms by which prey avoid predator attacks and explores how such defensive mechanisms have evolved through natural selection. It considers how potential prey avoid detection, how they make themselves unprofitable to attack, how they communicate this status, and how other species have exploited these signals. Using carefully selected examples of camouflage, mimicry, and warning signals drawn from a wide range of species and ecosystems, the authors summarise the latest research into these fascinating adaptations, developing mathematical models where appropriate and making recommendations for future study. This second edition has been extensively rewritten, particularly in the application of modern genetic research techniques which have transformed our recent understanding of adaptations in evolutionary genomics and phylogenetics. The book also employs a more integrated and systematic approach, ensuring that each chapter has a broader focus on the evolutionary and ecological consequences of anti-predator adaptation. The field has grown and developed considerably over the last decade with an explosion of new research literature, making this new edition timely.
