Available in PDF, EPUB and Kindle. Book excerpt: Whether in felling trees for wood, rearing insects for biological control, or culling animals for conservation purposes, efficient management of biological systems requires quantitative analysis of population growth and harvesting policies. Aiming to encourage the exchange of ideas among scientists involved in the management of fisheries, wildlife, forest stands, and pest control, the authors of this work present a general framework for modeling populations that reproduce seasonally and that have age or stage structure as an essential component of management strategy. The book represents the first time that examples from such diverse areas of biological resource management have been brought together in a unified modeling framework using the standard notation of mathematical systems theory. In addition, the authors combine a nonlinear extension of Leslie matrix theory and certain linear elements, thereby permitting interesting analytical results and the creation of compact, realistic simulation models of resource systems.

This book was released on 2020-03-31 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although ecologists have long considered morphology and life history to be important determinants of the distribution, abundance, and dynamics of plants in nature, this book contains the first theory to predict explicitly both the evolution of plant traits and the effects of these traits on plant community structure and dynamics. David Tilman focuses on the universal requirement of terrestrial plants for both below-ground and above-ground resources. The physical separation of these resources means that plants face an unavoidable tradeoff. To obtain a higher proportion of one resource, a plant must allocate more of its growth to the structures involved in its acquisition, and thus necessarily obtain a lower proportion of another resource. Professor Tilman presents a simple theory that includes this constraint and tradeoff, and uses the theory to explore the evolution of plant life histories and morphologies along productivity and disturbance gradients. The book shows that relative growth rate, which is predicted to be strongly influenced by a plant's proportional allocation to leaves, is a major determinant of the transient dynamics of competition. These dynamics may explain the differences between successions on poor versus rich soils and suggest that most field experiments performed to date have been of too short a duration to allow unambiguous interpretation of their results.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together the work of over twenty-five researchers to provide a comparative and empirically rich portrait of community forestry policy and practice in Canada. Tackling all forestry regions from Newfoundland to British Columbia, it unearths the history of community forestry across the nation, demonstrating strong regional differences tied to patterns of policy-making and cultural traditions. Case studies reveal innovative practices in governance and ecological management but also uncover challenges related to government support and market access. This book also considers the future of the sector, including the role of institutional reform, multiscale networks, and adaptive management strategies.

Book excerpt: "This book presents a synthesis of published information on mountain pine beetle (Dendroctonus ponderosae Hopkins [Coleoptera: Scolytidae]) biology and management with an emphasis on lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests of western Canada. Intended as a reference for researchers as well as forest managers, the book covers three main subject areas: mountain pine beetle biology, management, and socioeconomic concerns. The chapters on biology cover taxonomy, life history and habits, distribution, insect-host tree interactions, development and survival, epidemiology, and outbreak history. The management section covers management strategy, survey and detection, proactive and preventive management, and decision support tools. The chapters on socioeconomic aspects include an economic examination of management programs and the utilization of post-beetle salvage timber in solid wood, panelboard, pulp and paper products."--Publisher's description.

Available in PDF, EPUB and Kindle. Book excerpt: Natural killer (NK) cells are innate lymphoid cells that have a significant role in regulating the defenses against cancer development and certain viral infections. They are equipped with an array of activating and inhibitory receptors that stimulate or diminish NK cell activity, respectively. Inhibitory receptors include, among others, the MHC class I ligands killer cell immunoglobulin-like receptors (KIR) in humans, and members of the Ly49 family of receptors in mice, and CD94/NKG2A. Activating receptors include cytokine and chemokine receptors, and those that interact with ligands expressed on target cells, such as the natural cytotoxicity receptors or NCRs (NKp30, NKp44 and NKp46), NKG2D, CD244 and DNAM-1. In addition, NK cells express Fc?RIIIA or CD16, the receptor that exerts antibody-dependent cell mediated cytotoxicity (ADCC). NK cells also express the death ligands FasL and TRAIL. The killing or sparing of target cells depends on the integration of distinct signals that originate from NK cell receptors. NK cells spare healthy cells that express normal levels of MHC class I molecules and low amounts of stress-induced self-molecules, whereas they kill target cells that down-regulate MHC class I molecules and/or up-regulate stress-induced self-molecules. The latter are common signatures of virus-infected cells and tumors. All the accumulated knowledge on NK cell biology, along with many clinical observations, is driving multiple efforts to improve the arsenal of NK cell-based therapeutic tools in the fight against malignant diseases. Indeed, NK cell-based immunotherapy is becoming a promising approach for the treatment of many cancers. It is well known that NK cells have a significant role in the anti-tumor effect of therapeutic antibodies that use ADCC as a mechanism of action. In addition to this, administration of autologous and allogeneic NK cells after activation and expansion ex vivo is used in the treatment of cancer. Moreover, adoptive transfer of NK cell lines has been tested in humans, and genetically modified NK cells expressing chimeric antigen receptors are being studied in preclinical models for potential use in the clinic.

Available in PDF, EPUB and Kindle. Book excerpt: Our requirement for plant breeders to be successful has never been greater. However one views the forecasted numbers for future population growth we will need, in the immediate future, to be feeding, clothing and housing many more people than we do, inadequately, at present. Plant breeding represents the most valuable strategy in increasing our productivity in a way that is sustainable and environmentally sensitive. Plant breeding can rightly be considered as one of the oldest multidisciplin ary subjects that is known to humans. It was practised by people who first started to carry out a settled form of agriculture. The art, as it must have been at that stage, was applied without any formal underlying framework, but achieved dramatic results, as witnessed by the forms of cultivated plants we have today. We are now learning how to apply successfully the results of yet imperfect scientific knowledge. This knowledge is, however, rapidly develop ing, particularly in areas of tissue culture, biotechnology and molecular biology. Plant breeding's inherent multifaceted nature means that alongside obvious subject areas like genetics we also need to consider areas such as: statistics, physiology, plant pathology, entomology, biochemistry, weed science, quality, seed characteristics, reproductive biology, trial design, se lection and computing.

Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity loss is one of the major resource problems facing the world, and the policy options available are restricted by inappropriate economic tools which fail to capture the value of species and their variety. This study describes in non-technical terms how cost-benefit analysis techniques can be applied to species and species loss, and how they provide a measure of the efficiency of conservation measures. Only when conservation can be shown to pass such a basic economic test, the authors claim, will it be incorporated into policies.;David Pearce has also written Blueprint for a Green Economy.

Available in PDF, EPUB and Kindle. Book excerpt: By the year 2000, the world had built more than 45,000 large dams to irrigate crops, generate power, control floods in wet times and store water in dry times. Yet, in the last century, large dams also disrupted the ecology of half the world's rivers, displaced tens of millions of people from their homes and left nations burdened with debt. Their impacts have inevitably generated growing controversy and conflicts. Resolving their role in meeting water and energy needs is vital for the future and illustrates the complex development challenges that face our societies. The Report of the World Commission on Dams: - is the product of an unprecedented global public policy effort to bring governments, the private sector and civil society together in one process - provides the first comprehensive global and independent review of the performance and impacts of dams - presents a new framework for water and energy resources development - develops an agenda of seven strategic priorities with corresponding criteria and guidelines for future decision-making. Challenging our assumptions, the Commission sets before us the hard, rigorous and clear-eyed evidence of exactly why nations decide to build dams and how dams can affect human, plant and animal life, for better or for worse. Dams and Development: A New Framework for Decision-Making is vital reading on the future of dams as well as the changing development context where new voices, choices and options leave little room for a business-as-usual scenario.
