This book was released on 2009 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Wildlife Trees play a significant role in maintaining species richness in forested ecosystems by providing critical habitat. This study was completed to develop a better understanding of the relationship between ecosystem and tree attributes and an established functional Wildlife Tree type classification. Data from four studies conducted in different ecosystems in central British Columbia are compared in this paper. The four study areas were: (1) boreal aspen forests, (2) mixed conifer forests in the boreal foothills, (3) mixed conifer forests in the moist interior plateau, and (4) mixed conifer forests in the interior wet belt. In each study area, tree species were evaluated by diameter classes for the percentage of live versus dead stems and functional Wildlife Tree types based on an existing classification system, and results within and among study areas were then compared. The combined tree sample size totalled almost 19 300 stems, comprising 10 different tree species. To provide a link to provincial Wildlife Tree policy, each tree's value was ranked using guidelines established by the provincial Wildlife Tree Committee."--Document.

This book was released on 2019-04-01 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The American chestnut, whitebark pine, and several species of ash in the eastern United States are just a few of the North American tree species that have been functionally lost or are in jeopardy of being lost due to outbreaks of pathogens and insect pests. New pressures in this century are putting even more trees at risk. Expanded human mobility and global trade are providing pathways for the introduction of nonnative pests for which native tree species may lack resistance. At the same time, climate change is extending the geographic range of both native and nonnative pest species. Biotechnology has the potential to help mitigate threats to North American forests from insects and pathogens through the introduction of pest-resistant traits to forest trees. However, challenges remain: the genetic mechanisms that underlie trees' resistance to pests are poorly understood; the complexity of tree genomes makes incorporating genetic changes a slow and difficult task; and there is a lack of information on the effects of releasing new genotypes into the environment. Forest Health and Biotechnology examines the potential use of biotechnology for mitigating threats to forest tree health and identifies the ecological, economic, and social implications of deploying biotechnology in forests. This report also develops a research agenda to address knowledge gaps about the application of the technology.
Download or read book Forest Ecosystems written by Juan A. Blanco and published by BoD – Books on Demand. This book was released on 2012-03-07 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: The common idea for many people is that forests are just a collection of trees. However, they are much more than that. They are a complex, functional system of interacting and often interdependent biological, physical, and chemical components, the biological part of which has evolved to perpetuate itself. This complexity produces combinations of climate, soils, trees and plant species unique to each site, resulting in hundreds of different forest types around the world. Logically, trees are an important component for the research in forest ecosystems, but the wide variety of other life forms and abiotic components in most forests means that other elements, such as wildlife or soil nutrients, should also be the focal point in ecological studies and management plans to be carried out in forest ecosystems. In this book, the readers can find the latest research related to forest ecosystems but with a different twist. The research described here is not just on trees and is focused on the other components, structures and functions that are usually overshadowed by the focus on trees, but are equally important to maintain the diversity, function and services provided by forests. The first section of this book explores the structure and biodiversity of forest ecosystems, whereas the second section reviews the research done on ecosystem structure and functioning. The third and last section explores the issues related to forest management as an ecosystem-level activity, all of them from the perspective of the "other" parts of a forest.
Download or read book Individual based Methods in Forest Ecology and Management written by Arne Pommerening and published by Springer Nature. This book was released on 2019-09-17 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Model-driven individual-based forest ecology and individual-based methods in forest management are of increasing importance in many parts of the world. For the first time this book integrates three main fields of forest ecology and management, i.e. tree/plant interactions, biometry of plant growth and human behaviour in forests. Individual-based forest ecology and management is an interdisciplinary research field with a focus on how the individual behaviour of plants contributes to the formation of spatial patterns that evolve through time. Key to this research is a strict bottom-up approach where the shaping and characteristics of plant communities are mostly the result of interactions between plants and between plants and humans. This book unites important methods of individual-based forest ecology and management from point process statistics, individual-based modelling, plant growth science and behavioural statistics. For ease of access, better understanding and transparency the methods are accompanied by R code and worked examples.
Download or read book Quantifying Functional Biodiversity written by Laura Pla and published by Springer Science & Business Media. This book was released on 2011-11-02 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book synthesizes current methods used to quantify functional diversity, providing step-by-step examples for defining functional groups and estimating functional indices. The authors show how to compare communities, and how to analyze changes of diversity along environmental gradients, using real-life examples throughout. One section of the book demonstrates the selection of traits, and the standardization and characterization of ecosystem data. Another section presents methods used to quantify functional diversity, shows how to relate functional diversity with environmental variables and how to connect these to ecosystem services. The concluding section introduces FDiversity, a free program developed by the authors. The reader is guided through every step from software installation and basic functions, to sample and database design, to graphical projection methods, employing case study data to illustrate key concepts.

Download or read book Ecology Volume II written by Antonio Bodini and published by EOLSS Publications. This book was released on 2009-10-20 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology is a component of Encyclopedia of Environmental and Ecological Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Ecology is the study of the interrelationships between living organisms and their environment. The term "ecology" was introduced by Ernst Haeckel, at the end of the nineteenth century. Since that time spectacular advances have been made. Much has been learned about the relationship between organisms and environmental factors, and about the processes that regulate the abundance and distribution of species. The Theme on Ecology with contributions from distinguished experts in the field discusses the Science of Ecology for a Sustainable World. The two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
