Download or read book Arthropods of Tropical Forests written by Yves Basset and published by Cambridge University Press. This book was released on 2003-01-23 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arthropods are the most diverse group of organisms on our planet and the tropical rainforests represent the most biologically diverse of all ecosystems. This book, written by 79 authors contributing to 35 chapters, aims to provide an overview of data collected during recent studies in Australia, Africa, Asia, and South America. The book focuses on the distribution of arthropods and their use of resources in the rainforest canopies, providing a basis for comparison between the forest ecosystems of the main biogeographical regions. Topics covered include the distribution of arthropods along vertical gradients and the relationship between the soil/litter habitat and the forest canopy. The temporal dynamics of arthropod communities, habitats and food selection are examined within and among tropical tree crowns, as are the effects of forest disturbance. This important book is a valuable addition to the literature used by community ecologists, conservation biologists entomologists, botanists and forestry experts.
Download or read book Costa Rican Ecosystems written by Maarten Kappelle and published by University of Chicago Press. This book was released on 2016-04-15 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1502, Christopher Columbus named Costa Rica, and while gold and silver never materialized to justify the moniker of rich coast in purely economic terms, scientists and ecotravelers alike have long appreciated its incredible wealth. Wealth in Costa Rica is best measured by its biodiversityhome to a dizzying number of plants and animals, many endemic, it s a country that has long encouraged and welcomed researchers from the world over, and is exemplary in the creation and commitment to indigenous conservation and management programs. Costa Rica is considered to have the best preserved natural resources in Latin America. Approximately nine percent (about 1,000,000 acres) of Costa Rica has been protected in 15 national parks, and a comparable amount of land is protected as wildlife refuges, forest reserves or Indian reservations. This long-awaited synthesis of Costa Rican ecosystems is an authoritative presentation of the paleoecology, biogeography, structure, conservation, and sustainable use of Costa Rica s ecosystems. It systematically covers the entire range of Costa Rica s natural and managed, terrestrial, freshwater and marine ecosystems, including its island systems (Cocos Islands), the Atlantic and Pacific oceans and shores (coasts, coral reefs, mangrove forests), its lowlands (dry, season and wet forests), its highlands (the northern volcanoes and southern Talamanca s), and its estuaries, rivers, lakes, swamps and bogs. The volume s integrated, comprehensive format will be welcomed by tropical and temperate biologists alike, by biogeographers, plant and animal ecologists, marine biologists, conservation biologists, foresters, policy-makers and all scientists, natural history specialists and all with an interest in Costa Rica s ecosystems."
Download or read book Plant Conservation written by Gary A. Krupnick and published by . This book was released on 2005 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural history has always been the foundation of conservation biology. For centuries, botanists collected specimens in the field to understand plant diversity; now that many habitats are threatened, botanists have turned their focus to conservation, and, increasingly, they look to the collections of museums, herbaria, and botanical gardens for insight on developing informed management programs. Plant Conservation explores the value of these collections in light of contemporary biodiversity studies. Plant Conservation opens with a broad view of plant biodiversity and then considers evolutionary and taxonomic threats and consequences of habitat alteration; specific threats to plant diversity, such as invasive species and global climate change; consequences of plant population decline at the ecological, evolutionary, and taxonomic levels; and, finally, management strategies that protect plant biodiversity from further decline. With a unique perspective on biodiversity and scientific collections, Plant Conservation ultimately emphasizes the role museums and botanical gardens will play in future conservation.
Download or read book Random Fragmentation and Coagulation Processes written by Jean Bertoin and published by Cambridge University Press. This book was released on 2006-08-10 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fragmentation and coagulation are two natural phenomena that can be observed in many sciences and at a great variety of scales - from, for example, DNA fragmentation to formation of planets by accretion. This book, by the author of the acclaimed Lévy Processes, is the first comprehensive theoretical account of mathematical models for situations where either phenomenon occurs randomly and repeatedly as time passes. This self-contained treatment develops the models in a way that makes recent developments in the field accessible. Each chapter ends with a comments section in which important aspects not discussed in the main part of the text (often because the discussion would have been too technical and/or lengthy) are addressed and precise references are given. Written for readers with a solid background in probability, its careful exposition allows graduate students, as well as working mathematicians, to approach the material with confidence.

Download or read book Forests and Insects written by Allan D. Watt and published by Springer Science & Business Media. This book was released on 1997-09-30 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the full breadth of forest entomology. It combines the work of forest entomologists working on the impact and management of forest pests with those involved in diversity assessment and conservation of insects in forests. Forests and Insects demonstrates that both these disciplines demand an understanding of population and community biology. The book covers such topics as colonization of trees by insects, population dynamics of forest insects, insect natural enemies, the effects of climate change and pollution on forest pests, spatial variation in the abundance of insects,the mineralization of carbon by termites, the impact of herbivorous insects, and the conservation of forest insect diversity, including the effects of forest fragmentation and deforestation. This Royal Entomological Society Symposium volume will be of great interest to all agricultural and forest entomologists, population and community biologists, pest management specialists and anyone concerned with the conservation of forest biodiversity.
Download or read book Caterpillars written by Nancy E. Stamp and published by Springer. This book was released on 1993 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caterpillars are excellent model systems for the investigation of insect-plant interactions, predator-prey interactions, and insect physiology. Despite this, however, there is at present only a limited understanding of the constraints on foraging patterns of caterpillars. A major problem is the difficulty of designing and analyzing experiments which account for multiple constraints. Caterpillars: Ecological and Evolutionary Constraints on Foraging reviews the present state of research into caterpillar biology while arguing for a multiple factor approach in studying insect herbivores. Written by leading authorities in entomology and ecology, it provides an explicit framework for carrying out such investigations. The book details the constraints of the foraging patterns of caterpillars, including phylogenetic constraints, the physical environment, nutritional supply and demand, predators, and plant chemical defenses. It also analyzes caterpillar adaptations, such as sociality, mutualism, aposematism, and cryptic morphology, and covers population dynamics and the influence of environmental factors upon tropical, temperate, and arctic caterpillars. The book concludes with a discussion of the implications of this material for pest management, forest systems, and agroecosystems.

Download or read book Handbook of Ecological Restoration written by Martin R. Perrow and published by Cambridge University Press. This book was released on 2002-09-05 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume handbook is a comprehensive account of the rapidly emerging and vibrant science of the ecological restoration of habitats and species. Ecological restoration aims to achieve complete structural, functional, self-maintaining biological integrity following disturbance. In practice, any theoretical model is modified by a number of economic, social, and ecological constraints. Consequently, material that might be considered as rehabilitation, enhancement, re-construction, or re-creation is also included. Principles of Restoration defines the underlying principles of restoration ecology in relation to manipulations and management of the biological, geophysical, and chemical framework.
Download or read book Chalcidoidea of Iran written by Hassan Ghahari and published by CABI. This book was released on 2021-01-27 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: The superfamily Chalcidoidea (Insecta, Hymenoptera) contains in excess of 26,000 described species worldwide, but with an estimated total diversity of more than 500,000 species the vast majority of species have yet to be discovered and described. Most chalcidoid species are parasitoids of hosts in at least 12 different insect orders, attacking the egg, larval or pupal stages, though phytophagy and other life cycles and hosts are known. Iran is the 18th largest country in the world and has a rich and diverse insect fauna, including Chalcidoidea. It is extremely interesting from a biogeographic point of view, and a paradise for an entomologist. This book summarizes the results of all prior research concerning species diversity of Iranian Chalcidoidea, including host records and distribution records by province in Iran as well as world distribution by country for 1,351 species of Chalcidoidea recorded from Iran through the end of 2019.
Download or read book 100 Caterpillars written by Jeffrey C. Miller and published by La Editorial, UPR. This book was released on 2006 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every bright monarch butterfly or striking luna moth started out in a far subtler form of nature's mosaic, a humble caterpillar. It is this early stage of life--crafted by natural selection into machines for converting a vast array of plant matter, mostly leaves, into the beautiful adults that have captivated humans for millennia--that this book brings to dazzling light. Unobtrusive as they go about their business, these caterpillars are rarely seen by humans--and are virtually never seen from the perspective presented in this sumptuous volume: photographed in extreme close-ups at a resolution that captures in sharp detail the exquisite colors and features eluding the casual observer. Gathered by biologists Daniel Janzen, Winifred Hallwachs, and Jeffrey Miller in the tropical dry forests, cloud forests, and rain forests of northwestern Costa Rica, over 100 large-format photographs of caterpillars document the dizzying variety of shapes, vivid colors, and cryptic markings among these species. The pictures are accompanied by capsule species accounts--revealing life histories as diverse as their forms--and magnificent images of the adult butterfly or moth. Throughout, the authors convey an intimate sense of these creatures--studied over twenty-five years--by focusing on how their features figure in their behavior and ecology, and on the beauty of nature in this life stage, as well as the nature of that beauty. The story of the caterpillars is also the success story of Area de Conservacion Guanacaste--where the long-term work of Janzen and Hallwachs, and a team of gusaneros (caterpillar collectors and rearers), along with the participation of neighboring farming communities, has deepened understanding of Costa Rica's Lepidoptera and has brought about advances in restoration ecology of tropical habitats, biodiversity prospecting, biological control of pests, biotechnology, residents' bioliteracy, and ecotourism development.
Download or read book 100 Butterflies and Moths written by Jeffrey C. Miller and published by Harvard University Press. This book was released on 2007 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Walking a forest trail in Costa Rica, a visitor might be struck by the sight of an iridescent blue morpho butterfly fluttering ahead in the filtered daylight, or an enormous silk moth, as magnificently patterned and subtly colored as a Persian carpet, only emerging to fly at night. Elsewhere, vivid yellow and orange sulphur butterflies flock to puddles to sip the concentrated minerals. Such is the dazzling variety of the butterflies and moths unique to this region. Gathered by biologists Daniel Janzen and Winifred Hallwachs in the forests of northwestern Costa Rica, 100 tropical butterflies and moths represent the diversity in large-format photographs by Jeffrey Miller that document the dizzying variety of shapes, colors, and markings. The photographs are accompanied by species accounts and images of the corresponding caterpillar. The authors recount these insects' feats of mimicry and migration, lift the veil on their courtship, and show how the new technology of DNA barcoding is changing the picture of Lepidopteran biodiversity. The authors also tell the success story of Area de Conservacion Guanacaste, where the long-term work of Janzen and Hallwachs, a team of caterpillar collectors, and the participation of neighboring farming communities has deepened understanding of Costa Rica's Lepidoptera and has brought about advances in restoration ecology of tropical habitats, biodiversity prospecting, biotechnology, and ecotourism development.
Download or read book Hymenoptera and Biodiversity written by John LaSalle and published by Oxford University Press, USA. This book was released on 1993 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing attention has been focused on biodiversity in recent years, based on a number of arguments to justify the conservation of the world's flora and fauna. Such arguments may be economic - that species may have potential for food or medicine - or ecological - that the extinction of any species affects the overall ecological balance. Little attention, however, has been focused on which groups have the greatest impact on maintaining diversity. Hymenoptera is one of these groups. It not only forms a major component of diversity itself, but is vital in sustaining diversity in other groups. Hymenoptera species (bees, wasps, ants and sawflies) are major plant pollinators, seed dispersers and parasitoids and predators of other arthropods (and hence important in biological control). This volume therefore tackles an important subject and concentrates on three key issues: how species of Hymenoptera affect diversity in other organisms; whether Hymenoptera is a group prone to extinction; and the consequences if Hymenoptera species are differentially removed from terrestrial ecosystems. The book is essential reading for entomologists and those concerned with biodiversity and conservation.
