Book Description
Small enough to carry in a backpack, this comprehensive guide explores the many diverse natural communities of Michigan, providing detailed descriptions, distribution maps, photographs, lists of characteristic plants, suggested sites to visit, and a dichotomous key for aiding field identification. This is a key tool for those seeking to understand, describe, document, conserve, and restore the diversity of natural communities native to Michigan.

Book Description
This open access book describes the serious threat of invasive species to native ecosystems. Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.

Book Description
In 1984, a new research working party on mechanismsofwoody plant resistance against insects and pathogens(lUFROS2. 05-06) was formed in the International Union ofForestryResearchOrganizations. Thepurposeofthisworkingparty istostimulate and facilitate research progress in this areathroughenhancedcommunication among themany researchscientistsscatteredamongthevariouscountriesoftheworld. This volume istheresultofthe first internationalsymposiumofthisworkingparty, which took place in Orleans. France on August 26-29, 1986. Thanks are due to Institute Nationalde laRechercheAgronomique, StationdeZoologie, Forestiere, fortheir in- strumental part in organizingthis symposium, and to the University and the Cityof Orleansforgenerousfinancial support. The intentofthis proceedings is to (a) bring together adiverse array ofresearch resultsonthemechanismsofwoodyplantresistanceagainstdifferentkindsofinsects. and(b) to search for threadsofcommonality among these different plant/insect as- sociationstofurtherourfundamental understandingofhowplantsdefendthemselves againstphytophagousorganisms. Theresearchpapersareorganizedintothreemaingroups. Thefirstgroupexamines plant defenses from various basic physiological and ecological considerations. The remaining papers, which are mainly case studiesofplant resistance against insects. arecategorizedon the basisofinsect intimacy with host tissues: (a) highly mobile. free feeders suchas moth larvae andsawflies, and (b)poorlymobile, "attached" or imbeddedfeederssuchasaphids, scales, miners, andbarkbeetles.

Book Description
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.

Book Description
The landscapes of North America, including eastern forests, have been shaped by humans for millennia, through fire, agriculture, hunting, and other means. But the arrival of Europeans on America’s eastern shores several centuries ago ushered in the rapid conversion of forests and woodlands to other land uses. By the twentieth century, it appeared that old-growth forests in the eastern United States were gone, replaced by cities, farms, transportation networks, and second-growth forests. Since that time, however, numerous remnants of eastern old growth have been discovered, meticulously mapped, and studied. Many of these ancient stands retain surprisingly robust complexity and vigor, and forest ecologists are eager to develop strategies for their restoration and for nurturing additional stands of old growth that will foster biological diversity, reduce impacts of climate change, and serve as benchmarks for how natural systems operate. Forest ecologists William Keeton and Andrew Barton bring together a volume that breaks new ground in our understanding of ecological systems and their importance for forest resilience in an age of rapid environmental change. This edited volume covers a broad geographic canvas, from eastern Canada and the Upper Great Lakes states to the deep South. It looks at a wide diversity of ecosystems, including spruce-fir, northern deciduous, southern Appalachian deciduous, southern swamp hardwoods, and longleaf pine. Chapters authored by leading old-growth experts examine topics of contemporary forest ecology including forest structure and dynamics, below-ground soil processes, biological diversity, differences between historical and modern forests, carbon and climate change mitigation, management of old growth, and more. This thoughtful treatise broadly communicates important new discoveries to scientists, land managers, and students and breathes fresh life into the hope for sensible, effective management of old-growth stands in eastern forests.

Book Description
For nearly 50 years, pest control was mostly based on broad-spectrum conv- tional insecticides such as organochlorines, organophosphates, carbamates and pyrethroids. However, the severe adverse effects of pesticides on the environment, problems of resistance reaching crisis proportions and public protests led to stricter regulations and legislation aimed at reducing their use. Ways to reduce the use of synthetic pesticides in plant protection and to use more alternative and novel me- ods for pest control or biorational control are the challenges of pest control for the twenty-first century. The term biorational (biological + rational) pesticides can be defined as the use of specific and selective chemicals, often with a unique modes of action, that are compatible with natural enemies and the environment, with minimal effect on n- target organisms. Biorational control is based on a diversity of chemical, biological and physical approaches for controlling insect pests which results in minimum risk to man and the environment.
