Download or read book The Assessment and Modeling of Regeneration Dynamics for Eastern White Pine Pinus Strobus L written by Jerome Allan Krueger and published by . This book was released on 2002 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study represents an analysis of regeneration processes for eastern white pine (Pinus strohus L.). The objective is to develop an integrated approach to evaluate the influence of factors that, alone and in combination, determine regeneration outcomes. This study is composed of three sections. The first chapter is a literature review of white pine regeneration dynamics. The purpose is to present a process for understanding the regeneration process of a single species and present a conceptual approach to integrated evaluation of influential variables. Six interrelated ecological factors (seed tree density, competition, disturbance, seedbed conditions, soils, and damage agents) were identified and their impact on the regeneration process is evaluated. A conceptual model of the integration approach and two examples of how this approach can be utilized in assessing regeneration operations are presented.

This book was released on 2017-10-28 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Predicting the Effect of Fire on Large-Scale Vegetation Patterns in North America Ecological considerations provide constraints on the vegetation transitions produced by these reductions of lai, and additional insight into successional dynamics and changes in species composition. For example, fire can cause changes in the domi nant plant phenology or leaf type in a biome without obligatory changes in lal. Under standing how ecological effects preset the initial conditions to which fire behavior models are applied will be a key step in integrating biotic and abiotic processes, to effectively model the mechanisms of change at the biome scale.

Download or read book Research Agenda for Integrated Landscape Modeling written by Sam Cushman and published by . This book was released on 2007 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliable predictions of how changing climate and disturbance regimes will affect forest ecosystems are crucial for effective forest management. Current fire and climate research in forest ecosystem and community ecology offers data and methods that can inform such predictions. However, research in these fields occurs at different scales, with disparate goals, methods, and context. Often results are not readily comparable among studies and defy integration. We discuss the strengths and weaknesses of three modeling paradigms: empirical gradient models, mechanistic ecosystem models, and stochastic landscape disturbance models. We then propose a synthetic approach to multi-scale analysis of the effects of climatic change and disturbance on forest ecosystems. Empirical gradient models provide an anchor and spatial template for stand-level forest ecosystem models by quantifying key parameters for individual species and accounting for broad-scale geographic variation among them. Gradient imputation transfers predictions of fine-scale forest composition and structure across geographic space. Mechanistic ecosystem dynamic models predict the responses of biological variables to specific environmental drivers and facilitate understanding of temporal dynamics and disequilibrium. Stochastic landscape dynamics models predict frequency, extent, and severity of broad-scale disturbance. A robust linkage of these three modeling paradigms will facilitate prediction of the effects of altered fire and other disturbance regimes on forest ecosystems at multiple scales and in the context of climatic variability and change.

Download or read book Ecoregions written by Robert G. Bailey and published by Springer Science & Business Media. This book was released on 2014-04-03 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global warming and human-driven impacts are changing the World’s ecological zones. This book applies the principles described in Bailey’s Ecosystem Geography: From Ecoregions to Sites, 2nd ed. (Springer 2009, 1st ed. 1996) to describe and characterize the major terrestrial and aquatic ecological zones of the Earth. Bailey’s system for classifying these zones has been adopted by major organizations such as the U.S. Forest Service and The Nature Conservancy and this book is a significant contribution to a long tradition of classifying and studying the world’s ecological regions or ecoregions. It includes two color maps that show the major ecoregions of the continents and oceans. Also included are: - 106 illustrations with 55 in full color - A new chapter on mountains is included. - There are new sections that address concerns about how eco regions are changing under the relentless influence of humans and climate change - Another new feature is the discussion of using eco regional patterns to transfer research results and select sites for detecting climate change effects on ecosystem distribution - Use of ecoregional patterns to design monitoring networks and sustainable landscapes - Fire regimes in different regional ecosystems and their management implications.

Download or read book Cascading Effects of Fire Exclusion in Rocky Mountain Ecosystems written by Robert E. Keane and published by . This book was released on 2002 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The health of many Rocky Mountain ecosystems is in decline because of the policy of excluding fire in the management of these ecosystems. Fire exclusion has actually made it more difficult to fight fires, and this poses greater risks to the people who fight fires and for those who live in and around Rocky Mountain forests and rangelands. This paper discusses the extent of fire exclusion in the Rocky Mountains, then details the diverse and cascading effects of suppressing fires in the Rocky Mountain landscape by spatial scale, characteristic, and vegetation type. Also discussed are the varied effects of fire exclusion on some important, keystone ecosystems and human concerns.
