Book Synopsis Grassland Simulation Model by : G. S. Innis
Download or read book Grassland Simulation Model written by G. S. Innis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perspectives on the ELM Model and Modeling Efforts This volume is the major open-literature description of a comprehensive, pioneering ecological modeling effort. The ELM model is one of the major outputs of the United States Grassland Biome study, a contribution to the International Biological Program (IBP). Writing this introduction provides wel come personal opportunity to (i) review briefly the state of the art at the beginning of the ELM modeling effort in 1971, (ii) to discuss some aspects of the ELM model's role in relation to other models and other phases of the Grassland Biome study, and (iii) to summarize the evolution of ELM or its components since 1973. Pre-Program Historical Perspective My first major contacts with ecological simulation modeling were in 1960 when I was studying intraseasonal herbage dynamics and nutrient production on foothill grasslands in southcentral Montana, making year-round measurements of the aboveground live vegetation, the standing dead, and the litter. Limitations in funding and the rockiness of the foothill soils prevented measuring the dynamics of the root biomass, both live and dead. Herbage biomass originates in live shoots from which it could be translocated into live roots or the live shoots could transfer to standing dead or to litter. Standing dead vegetation must end up in the litter and the live roots eventually transfer to dead roots. Obviously, the litter and the dead roots must decay away.

Book Synopsis Southwood's Ecological Methods by : Peter A. Henderson
Download or read book Southwood's Ecological Methods written by Peter A. Henderson and published by Oxford University Press. This book was released on 2021-04-01 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Methods by the late T.R. E. Southwood and revised over the years by P. A. Henderson has developed into a classic reference work for the field biologist. It provides a handbook of ecological methods and analytical techniques pertinent to the study of animals, with an emphasis on non-microscopic animals in both terrestrial and aquatic environments. It remains unique in the breadth of the methods presented and in the depth of the literature cited, stretching right back to the earliest days of ecological research. The universal availability of R as an open source package has radically changed the way ecologists analyse their data. In response, Southwood's classic text has been thoroughly revised to be more relevant and useful to a new generation of ecologists, making the vast resource of R packages more readily available to the wider ecological community. By focusing on the use of R for data analysis, supported by worked examples, the book is now more accessible than previous editions to students requiring support and ideas for their projects. Southwood's Ecological Methods provides a crucial resource for both graduate students and research scientists in applied ecology, wildlife ecology, fisheries, agriculture, conservation biology, and habitat ecology. It will also be useful to the many professional ecologists, wildlife biologists, conservation biologists and practitioners requiring an authoritative overview of ecological methodology.
Book Synopsis Measuring Plant Diversity by : Thomas J. Stohlgren
Download or read book Measuring Plant Diversity written by Thomas J. Stohlgren and published by OUP USA. This book was released on 2007 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here is a thorough presentation and critique of the sampling approaches, designs and field techniques for measuring plant diversity. Ecologists interested in assessing landscapes and ecosystems must measure biomass, cover, and the density or frequency of various key species. Recently, sampling designs for measuring species richness and diversity, patterns of plant diversity, species-environment relationships, and species distributions have become finer-grained, as it has become increasingly important to accurately map and assess rare species for conservation. This book lays out the range of current methods for mapping and measuring species diversity, for field ecologists, resource managers, conservation biologists, and students, as a tool kit for future field measurements of plant diversity.

Book Synopsis Quaternary Extinctions by : Paul S. Martin
Download or read book Quaternary Extinctions written by Paul S. Martin and published by University of Arizona Press. This book was released on 2022-01-04 with total page 903 pages. Available in PDF, EPUB and Kindle. Book excerpt: "What caused the extinction of so many animals at or near the end of the Pleistocene? Was it overkill by human hunters, the result of a major climatic change or was it just a part of some massive evolutionary turnover? Questions such as these have plagued scientists for over one hundred years and are still being heatedly debated today. Quaternary Extinctions presents the latest and most comprehensive examination of these questions." —Geological Magazine "May be regarded as a kind of standard encyclopedia for Pleistocene vertebrate paleontology for years to come." —American Scientist "Should be read by paleobiologists, biologists, wildlife managers, ecologists, archeologists, and anyone concerned about the ongoing extinction of plants and animals." —Science "Uncommonly readable and varied for watchers of paleontology and the rise of humankind." —Scientific American "Represents a quantum leap in our knowledge of Pleistocene and Holocene palaeobiology. . . . Many volumes on our bookshelves are destined to gather dust rather than attention. But not this one." —Nature "Two strong impressions prevail when first looking into this epic compendium. One is the judicious balance of views that range over the whole continuum between monocausal, cultural, or environmental explanations. The second is that both the data base and theoretical sophistication of the protagonists in the debate have improved by a quantum leap since 1967." —American Anthropologist

Book Synopsis Ecological Methods by : T.R. Southwood
Download or read book Ecological Methods written by T.R. Southwood and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: The virtual impossibility of extracting the many different species from a habitat with equal efficiency by a single method (e.g. Nef, 1960). 1.1 Population estimates Population estimates can be classified into a number of different types; the most convenient classification is that adopted by Morris (1955), although he used the terms somewhat differently in a later paper (1960). 1.1.1 Absolute and related estimates The animal numbers may be expressed as a density per unit area of the ground of the habitat. Such estimates are given by nearest neighbour and related techniques (Chapter 2), marking and recapture (Chapter 3), by sampling a known fraction of the habitat (Chapter 4-6) and by removal sampling and random walk techniques (Chapter 7). Absolute population The number of animals per unit area (e.g. hectare, acre). It is almost impossible to construct a budget or to study mortality factors without the conversion of population estimates to absolute figures, for not only do insects often move from the plant to the soil at different developmental stages, but the amount of plant material is itself always changing. The importance of obtaining absolute estimates cannot be overemphasized.
Book Synopsis Plant Resistance to Herbivores and Pathogens by : Robert S. Fritz
Download or read book Plant Resistance to Herbivores and Pathogens written by Robert S. Fritz and published by University of Chicago Press. This book was released on 2012-07-15 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: Far from being passive elements in the landscape, plants have developed many sophisticated chemical and mechanical means of deterring organisms that seek to prey on them. This volume draws together research from ecology, evolution, agronomy, and plant pathology to produce an ecological genetics perspective on plant resistance in both natural and agricultural systems. By emphasizing the ecological and evolutionary basis of resistance, the book makes an important contribution to the study of how phytophages and plants coevolve. Plant Resistance to Herbivores and Pathogens not only reviews the literature pertaining to plant resistance from a number of traditionally separate fields but also examines significant questions that will drive future research. Among the topics explored are selection for resistance in plants and for virulence in phytophages; methods for studying natural variation in plant resistance; the factors that maintain intraspecific variation in resistance; and the ecological consequences of within-population genetic variation for herbivorous insects and fungal pathogens.
