Every ecosystem is a complex organization of carefully mixed life forms; a dynamic and particularly sensible system. Consequently, their progressive decline may accelerate climate change and vice versa, influencing flora and fauna composition and distribution, resulting in the loss of biodiversity. Climate changes effects are the principal topics of this volume. Written by internationally renowned contributors, Biodiversity loss in a changing planet offers attractive study cases focused on biodiversity evaluations and provisions in several different ecosystems, analysing the current life condition of many life forms, and covering very different biogeographic zones of the planet.

“The first English translation of the major work of a privileged, unconventional, and somewhat neglected Cuban author.” —Choice Eleven years before Uncle Tom’s Cabin fanned the fires of abolition in North America, an aristocratic Cuban woman told an impassioned story of the fatal love of a mulatto slave for his white owner's daughter. So controversial was Sab’s theme of miscegenation and its parallel between the powerlessness and enslavement of blacks and the economic and matrimonial subservience of women that the book was not published in Cuba until 1914, seventy-three years after its original 1841 publication in Spain. Also included in the volume is Avellaneda’s Autobiography (1839), whose portrait of an intelligent, flamboyant woman struggling against the restrictions of her era amplifies the novel's exploration of the patriarchal oppression of minorities and women. “A worthy addition to scholarship in Latin American studies, useful in comparative literature and social history courses covering such writers as Harriet Beecher Stowe, Jorge Isaacs, Alejo Carpentier, or Ramon del Valle-Inclán.” —Choice

Forest Plans of North America presents case studies of contemporary forest management plans developed for forests owned by federal, state, county, and municipal governments, communities, families, individuals, industry, investment organizations, conservation organizations, and others in the United States, Canada, and Mexico. The book provides excellent real-life examples of contemporary forest planning processes, the various methods used, and the diversity of objectives and constraints faced by forest owners. Chapters are written by those who have developed the plans, with each contribution following a unified format and allowing a common, clear presentation of the material, along with consistent treatment of various aspects of the plans. This work complements other books published by members of the same editorial team (Forest Management and Planning, Introduction to Forestry and Natural Resource Management), which describe the planning process and the various methods one might use to develop a plan, but in general do not, as this work does, illustrate what has specifically been developed by landowners and land managers. This is an in-depth compilation of case studies on the development of forest management plans by the different landowner groups in North America. The book offers students, practitioners, policy makers, and the general public an opportunity to greatly improve their appreciation of forest management and, more importantly, foster an understanding of why our forests today are what they are and what forces and tools may shape their tomorrow. Forest Plans of North America provides a solid supplement to those texts that are used as learning tools for forest management courses. In addition, the work functions as a reference for the types of processes used and issues addressed in the early 21st century for managing land resources. - Presents 40-50 case studies of forest plans developed for a wide variety of organizations, groups, and landowners in North America - Illustrates plans that have specifically been developed by landowners and land managers - Features engaging, clearly written content that is accessible rather than highly technical, while demonstrating the issues and methods involved in the development of the plans - Each chapter contains color photographs, maps, and figures

An appreciation of the beautiful, iconic, and endangered Eastern Hemlock and what it means to nature and society The Eastern Hemlock, massive and majestic, has played a unique role in structuring northeastern forest environments, from Nova Scotia to Wisconsin and through the Appalachian Mountains to North Carolina, Tennessee, and Alabama. A “foundation species” influencing all the species in the ecosystem surrounding it, this iconic North American tree has long inspired poets and artists as well as naturalists and scientists. Five thousand years ago, the hemlock collapsed as a result of abrupt global climate change. Now this iconic tree faces extinction once again because of an invasive insect, the hemlock woolly adelgid. Drawing from a century of studies at Harvard University’s Harvard Forest, one of the most well-regarded long-term ecological research programs in North America, the authors explore what hemlock’s modern decline can tell us about the challenges facing nature and society in an era of habitat changes and fragmentation, as well as global change.

"Scale - the understanding of ecological phenomena through levels of biological organization across time and space - is one of most important concepts in ecology. It is often challenging for ecologists to find systems that lend themselves to study across scales; however, Sarracenia, a pitcher plant indigenous to the eastern United States, is unique because it can be studied at a hierarchy of scales: individuals, communities, and whole ecosystems. Ecologists Aaron Ellison and Nicolas Gotelli have studied Sarracenia for decades and, in this book, they synthesize their research and show how this system can inform the broad and challenging question of scaling in ecology. The authors' goal is to deepen the current understanding of major ecological processes, and how they operate across scales"--
