Biological Control in Latin America and the Caribbean: Its Rich History and Bright Future (CABI Invasives Series)

by Hugo César Arredondo-Bernal Jorge L. Sifontes Anobel Barba Lorena Barra-Bucarei César Basso Wagner Bettiol Fermin Blanco Helga Blanco-Metzler Claudia Carolina Antúnez Guillermo Cabrera Walsh Carmen C. Castillo Charlotte E. Causton Ronald D. Cave

The book summarizes the history of biological control in Latin America and the Caribbean. Few publications provide historical detail and the records are, therefore, fragmented until now. By bringing information together in this book, we offer a more complete picture of important developments in biological control on this continent. There are a wealth of text, tables and references about the history of such projects, and which were successful and which failed. This will help plan future biocontrol projects. An overview is provided of the current situation in biological control for many Latin American and Caribbean countries, revealing an astonishing level of practical biological control applied in the region, making it the largest area under biological control worldwide. The final part describes new developments and speculates about the future of biological control in Latin America and the Caribbean.

Biological Economies: Experimentation and the politics of agri-food frontiers (Routledge Studies in Food, Society and the Environment)

by Michael Carolan Hugh Campbell Nick Lewis Richard Le Heron

Recent agri-food studies, including commodity systems, the political economy of agriculture, regional development, and wider examinations of the rural dimension in economic geography and rural sociology have been confronted by three challenges. These can be summarized as: ‘more than human’ approaches to economic life; a ‘post-structural political economy’ of food and agriculture; and calls for more ‘enactive’, performative research approaches. This volume describes the genealogy of such approaches, drawing on the reflective insights of more than five years of international engagement and research. It demonstrates the kinds of new work being generated under these approaches and provides a means for exploring how they should be all understood as part of the same broader need to review theory and methods in the study of food, agriculture, rural development and economic geography. This radical collective approach is elaborated as the Biological Economies approach. The authors break out from traditional categories of analysis, reconceptualising materialities, and reframing economic assemblages as biological economies, based on the notion of all research being enactive or performative.

Biological Invasions in South Africa (Invading Nature - Springer Series in Invasion Ecology #14)

by David M. Richardson John R. Wilson Brian W. van Wilgen John Measey Tsungai A. Zengeya

This open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.

Biology and Conservation of Horseshoe Crabs

by David Smith Mark L. Botton John T. Tanacredi

The four living species of horseshoe crabs face a set of growing threats to their survival, including the erosion and/or man-made alteration of essential spawning habitat, coastal pollution, and overfishing. Horseshoe crabs are "living fossils", with a more than 200 million year evolutionary history. Their blood provides a reagent, known as Limulus amebocyte lysate or LAL, that clots in the presence of minute quantities of bacterial endotoxin; the LAL test is the state-of-the-art methodology used to ensure that pharmaceuticals and surgical implants are free of contamination. Horseshoe crabs are an integral part of the food web in coastal marine ecosystems, and their eggs provide essential food for shorebirds in the Delaware Bay estuary each spring. The commercial fishery for horseshoe crabs, which utilizes animals for bait, contributes to the economies of coastal communities. This book consists of papers presented at the 2007 International Symposium on the Science and Conservation of Horseshoe Crabs.

Biology and Conservation of the European Sturgeon Acipenser sturio L. 1758: The Reunion of the European and Atlantic Sturgeons

by Eric Rochard Frank Kirschbaum Jörn Gessner Nathalie Desse-Berset Patrick Williot

The book aims at synthesizing our current knowledge of Acipenser sturio and its management. This species, one of the most widespread sturgeon species all over Western Europe ranging from the Black Sea to the Baltic, is now on the verge of extinction. Major aspects of its biology and management, including mismanagement, are provided in a historic perspective. Similarly, the changes in the restoration programs (in situ and ex situ) initiated in France and Germany are presented. As the species occurred in sympatry with Acipenser oxyrinchus in Germany and Poland and very recently in France as well, a brief outlook on restoration-management programs of A. oxyrinchus are also provided for both North America and Northern European countries, namely Germany and Poland. As conservation-restoration actions go beyond scientific issues, non-governmental stakeholders and marine professional fishermen's organizations have also been asked to contribute, and the key role of a French-German cooperation plan is underlined. A part of the book is devoted to perspectives. Illustrations of the European sturgeon, mainly in photographs, but also in stamps and paintings, are presented.

The Biology and Ecology of Giant Kelp Forests

by Michael S. Foster David R. Schiel

The largest seaweed, giant kelp (Macrocystis) is the fastest growing and most prolific of all plants found on earth. Growing from the seafloor and extending along the ocean surface in lush canopies, giant kelp provides an extensive vertical habitat in a largely two-dimensional seascape. It is the foundation for one of the most species-rich, productive, and widely distributed ecological communities in the world. Schiel and Foster's scholarly review and synthesis take the reader from Darwin's early observations to contemporary research, providing a historical perspective for the modern understanding of giant kelp evolution, biogeography, biology, and physiology. The authors furnish a comprehensive discussion of kelp species and forest ecology worldwide, with considerations of human uses and abuses, management and conservation, and the current and likely future impacts of global change. This volume promises to be the definitive treatise and reference on giant kelp and its forests for many years, and it will appeal to marine scientists and others who want a better appreciation and understanding of these wondrous forests of the sea.

Biology, Controls and Models of Tree Volatile Organic Compound Emissions (Tree Physiology #5)

by Russell K. Monson Ülo Niinemets

Plant-driven volatile organic compound (BVOC) emissions play a major role in atmospheric chemistry, including ozone and photochemical smog formation in the troposphere, and they extend the atmospheric lifetime of the key greenhouse gas, methane. Furthermore, condensation of photo-oxidation products of BVOCs leads to formation of secondary organic aerosols with profound implications for the earth's solar radiation budget and climate. Trees represent the plant life form that most contributes to BVOC emissions, which gives global forests a unique role in regulating atmospheric chemistry. Written by leading experts in the field, the focus is on recent advancements in understanding the controls on plant-driven BVOC emissions, including efforts to quantitatively predict emissions using computer models, particularly on elicitation of emissions under biotic and abiotic stresses, molecular mechanisms of volatile synthesis and emission and the role of emissions in plant stress tolerance.

The Biology of Aquatic and Wetland Plants

by Gary N. Ervin

Aquatic plants play a critically important role in maintaining ecosystem health. They are natural biological filters in freshwater and estuarine wetlands; they contribute to the reproductive success of many organisms, some of which are harvested for food; they assist in flood control; and they are prominent elements in the aesthetics and recreational use of freshwater and estuarine habitats. Despite this globally recognized importance, wetlands have faced and continue to face threats from the encroachment of human activities. The Biology of Aquatic and Wetland Plants is a thorough and up-to-date textbook devoted to these plants and their interactions with the environment. The focus is on botanical diversity from the perspective of evolutionary relationships, emphasizing the role of evolution in shaping adaptations to the aquatic environment. By incorporating recent findings on the phylogeny of green plants, with special emphasis on the angiosperms, the text is broadly useful for courses in plant biology, physiology, and ecology. Additionally, a chapter on population biology and evolutionary ecology complements the evolutionary backdrop of hydrophyte biology by examining the details of speciation and applications of modern genetic approaches to aquatic plant conservation. Key Features • Synthesizes recent and seminal literature on aquatic and wetland plants • Emphasizes evolutionary history as a factor influencing adaptations to the wetland environment • Provides a global perspective on plant diversity and threats facing wetland ecosystems • Highlights research needs in the field of aquatic and wetland plant biology • Includes 280 figures, with more than 300 color photographs, and 41 tables to provide ease of access to important concepts and information

The Biology Of Belief: Unleashing The Power Of Consciousness, Matter And Miracles

by Bruce Lipton

In The Biology Of Believe Bruce Lipton explores celular development and how the environment plays a much more important roll in how life develops than conventional science ever thought. He challenges the belief that genetics control how we and all life develop and thrive ground breaking research. We once believed that the world was round but now marvel that anyone would have thought this. Bruce Lipton along with many micro biologist genetics are the blue print and plans but our environment and beliefs are the catolist that determine the quality of life.

Biology of Earthworms (Soil Biology #24)

by Ayten Karaca

Earthworms, which belong to the order Oligochaeta, comprise roughly 3,000 species grouped into five families. Earthworms have been called 'ecosystem engineers'; much like human engineers, they change the structure of their environments. Earthworms are very versatile and are found in nearly all terrestrial ecosystems. They play an important role in forest and agricultural ecosystems. This Soil Biology volume describes the various facets of earthworms, such as their role in soil improvement, soil structure, and the biocontrol of soil-borne plant fungal diseases. Reviews discuss earthworms' innate immune system, molecular markers to address various issues of earthworm ecology, earthworm population dynamics, and the influences of organic farming systems and tillage. Further topics include the characteristics of vermicompost, relationships between soil earthworms and enzymes, the role of spermathecae, copulatory behavior, and adjustment of the donated sperm volume.

The Biology of Island Floras

by Juli Caujapé-Castells David Bramwell

Oceanic islands offer biologists unparalleled opportunities to study evolutionary processes and ecological phenomena. However, human activity threatens to alter or destroy many of these fragile ecosystems, with recent estimates suggesting that nearly half of the world's insular endemics are threatened with extinction. Bringing together researchers from around the world, this book illustrates how modern research methods and new concepts have challenged accepted theories and changed our understanding of island flora. Particular attention is given to the impact of molecular studies and the insights that they provide into topics such as colonisation, radiation, diversification and hybridisation. Examples are drawn from around the world, including the Hawaiian archipelago, Galapagos Islands, Madagascar and the Macronesian region. Conservation issues are also highlighted, with coverage of alien species and the role of ex situ conservation providing valuable information that will aid the formulation of management strategies and genetic rescue programmes.

The Biology of Reaction Wood

by Barry Gardiner John Barnett Pekka Saranpää Joseph Gril

The book is a fundamental reference source on reaction wood for wood scientists and technologists, plant biologists, silviculturists, forest ecologists, and anyone involved in the growing of trees and the processing of wood. It brings together our current understanding of all aspects of reaction wood, and is the first book to discuss both compression wood and tension wood. Trees produce reaction wood to maintain the vertical orientation of their stems and the optimum angle of each branch. They achieve this by laying down fibre cell walls in which differences in physical and chemical structure from those of normal fibres are expressed as differential stresses across the stem or branch. This process, while of obvious value for the survival of the tree, causes serious problems for the utilisation of timber. Timber derived from trees containing significant amounts of reaction wood is subject to dimensional instability on drying, causing twisting, bending and splitting. It is also difficult to work as timber, and for the pulp and paper industry the cost of removing the increased amount of lignin in compression wood is substantial. This has both practical and economic consequences for industry. Understanding the factors controlling reaction wood formation and its effect on wood structure is therefore fundamental to our understanding of the adaptation of trees to their environment and to the sustainable use of wood. The topics covered include: -Morphology, anatomy and ultrastructure of reaction wood -Cell-wall polymers in reaction wood and their biosynthesis -Changes in tree proteomes during reaction wood formation -The biomechanical action and biological functions of reaction wood - Physical and mechanical properties of reaction wood from the scale of cell walls to planks -The detection and characterisation of compression wood -Effects of reaction wood on the performance of wood and wood-based products - Commercial implications of reaction wood and the influence of forest management on its formation

New chapters have been added on termite pheromones, termites as pests of agriculture and on destructive invasive species.

Biology of Wonder: Aliveness, Feeling and the Metamorphosis of Science

by Andreas Weber

The disconnection between humans and nature is perhaps one of the most fundamental problems faced by our species today. The schism between us and the natural world is arguably the root cause of most of the environmental catastrophes unraveling around us. However, until we come to terms with the depths of our alienation, we will continue to fail to understand that what happens to nature also happens to us.In Healing Ecology author Andreas Weber proposes a new approach to the biological sciences that puts the human back in nature. He argues that feelings and emotions, far from being superfluous to the study of organisms, are the very foundation of life. From this basic premise flows the development of a "poetic ecology" which intimately connects our species to everything that surrounds us--showing that subjectivity and imagination are prerequisits of biological existence.Healing Ecology demonstrates that there is no separation between us and the world we inhabit, and in so doing it validates the essence of our deep experience. By reconciling science with meaning, expression and emotion, this landmark work brings us to a crucial understanding of our place in the rich and diverse framework of life-a revolution for biology as groundbreaking as the theory of relativity for physics. Dr. Andreas Weber is a German academic, scholar and author. He is a leader in the emerging fields of "biopoetics" and "biosemiotics," and his work has been translated into several languages and published around the globe.
