This book was released on 2013-01-25 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lands and waters of the Mid-Atlantic Region (MAR) have changed significantly since before the 16th century when the Susquehannock lived in the area. Much has changed since Captain John Smith penetrated the estuaries and rivers during the early 17th century; since the surveying of the Mason-Dixon Line to settle border disputes among Maryland, Pennsylvania, and Delaware during the middle of the 18th century; and since J. Thomas Scharf described the physiographic setting of Baltimore County in the late 19th century. As early as 1881, Scharf provides us with an assessment of the condition of the aquatic ecosystems of the region, albeit in narrative form, and already changes are taking place – the conversion of forests to fields, the founding of towns and cities, and the depletion of natural resources. We have always conducted our work with the premise that “man” is part of, and not apart from, this ecosystem and landscape. This premise, and the historical changes in our landscape, provide the foundation for our overarching research question: how do human activities impact the functioning of aquatic ecosystems and the ecosystem services that they provide, and how can we optimize this relationship?
Download or read book From Coastal Wilderness to Fruited Plain written by Gordon G. Whitney and published by Cambridge University Press. This book was released on 1996-08-29 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Coastal Wilderness to Fruited Plain is an account of the making of a large part of the American landscape following European settlement. Drawing upon land survey records and early travellers' accounts, Dr Whitney reconstructs the 'virgin' forests and grasslands of the north-eastern and central United States during the pre-settlement period. He then documents successively the clearance and fragmentation of the region's woodlands, the harvest of the forest and its game, the ploughing of the prairies, and the draining of wetlands. The degree to which these activities altered the soil, climate, plant and animal communities, and water cycle are evaluated, and the sustainability of present-day ecosystems is brought into question in this account.

Download or read book Bringing Nature Home written by Douglas W. Tallamy and published by Timber Press. This book was released on 2009-09-01 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: “With the twinned calamities of climate change and mass extinction weighing heavier and heavier on my nature-besotted soul, here were concrete, affordable actions that I could take, that anyone could take, to help our wild neighbors thrive in the built human environment. And it all starts with nothing more than a seed. Bringing Nature Home is a miracle: a book that summons butterflies." —Margaret Renkl, The Washington Post As development and habitat destruction accelerate, there are increasing pressures on wildlife populations. In his groundbreaking book Bringing Nature Home, Douglas W. Tallamy reveals the unbreakable link between native plant species and native wildlife—native insects cannot, or will not, eat alien plants. When native plants disappear, the insects disappear, impoverishing the food source for birds and other animals. Luckily, there is an important and simple step we can all take to help reverse this alarming trend: everyone with access to a patch of earth can make a significant contribution toward sustaining biodiversity by simply choosing native plants. By acting on Douglas Tallamy's practical and achievable recommendations, we can all make a difference.

Download or read book Concepts in Mycorrhizal Research written by K.G. Mukerji and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycorrhiza will be the focus of research and study for the coming decade. Successful survival and maintenance of plant cover is mostly dependent on mycorrhization. During the last decade about ten books have appeared on various aspects of mycorrhiza, including two on methodology. The present book has been compiled to give a complete and comprehensive description of the topic to the students and researchers in botany, applied mycology, biotechnology, forestry and agriculture. The book will also be useful to planners dealing with biofertilizers and forestation. Besides topics of academic interest, the volume includes several aspects which are unique and are written about for the first time, e.g.: Arbuscular Mycorrhizal symbiosis - recognition and specificity; Mycorrhizal Integration and cellular compatibility between Endomycorrhizal symbionts; Cost - economics of existing methodology for inoculum production of vesicular-arbuscular mycorrhizal fungi; Mycorrhiza: Ecological Implications of Plant interactions; Outplanting performance of mycorrhizal inoculated seedlings; Fluorescence microscopy in mycorrhiza studies and Ectomycorrhizal fungi as experimental organism. Other aspects not mentioned above include most recent reviews concerning vesicular-arbuscular mycorrhiza and ectomycorrhizae. The different review chapters have been written by world authorities in their respective specialisations giving more up to date information than is provided anywhere else. This book deals with all major aspects of mycorrhiza, giving structure, ultrastructure, ecology and applications in agriculture and forestry.
