Book Description
Breathe Easy with This Groundbreaking Gardening Guide If you are one of the millions of people with allergies or asthma, this totally unique book shows you how to avoid plants that trigger allergies and to create a garden that will actually protect you by trapping pollen and cleaning the air around you. This revolutionary approach combines the best of horticulturist Thomas Ogren’s previous books—Allergy-Free Gardening and Safe Sex in the Garden—into a full-color guide, including hundreds of new and updated plant listings and photographs. Ogren’s innovative system for combating allergens is based on the crucial matter of plant sex. By replacing troublesome male plants in your yard with pollen-blocking female “pollen screens,” allergy sufferers can reduce or eliminate their symptoms. More than 3,000 plant listings are included, accompanied by an easy-to-use allergy ranking scale of 1 to 10. With many new pollen-free plants to choose from, as well as clearly marked “worst offenders” to avoid, this is the ultimate resource for home gardeners and professionals alike who want to build healthy, safe, and beautiful gardens that everyone can enjoy.

Book Description
An understanding of the processes of plant reproduction is increasingly important in the exploitation of plant resources. Microspore formation is a major event in the life cycles of land plants, allowing the transition from diploid sporophyte generation to the haploid gametophyte generation, and varies greatly between taxa in the diversity of processes involved. Despite the wealth of information available, there are very few sources which bring together the results of research work on the reproduction in all the major plant groups.**Microspores fills this gap by reviewing microsporogenesis from a systematic and evolutionary perspective in groups ranging from algae to angiosperms. Special chapters focus on structure, function, cell and molecular processes, and potential biotechnological applications of plant spores and pollen. The result is an up-to-date guide to the applications of modern techniques in the classic area of botany.**This work bridges several disciplines to provide a coherent and authoritative account which will be essential reading for research scientists and lecturers in botany, evolution, ultrastructure, reproductive and developmental biology, and palynology.

Book Description
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.

Book Description
The Equatorial Rain Forest: A Geological History presents the equatorial vegetation as a dynamic entity with varied and highly significant history. It also discusses other types of equatorial regions. It addresses the vegetational history from a palaeoecological viewpoint. Some of the topics covered in the book are the vegetation of equatorial regions; the prelude to the quaternary; the quaternary vegetation of equatorial Latin America; the quaternary vegetation of equatorial Africa; the cretaceous period; and the quaternary vegetation of equatorial indo-malesia. The value of vegetational history is fully covered. The effect of man on vegetation is discussed in detail. The text describes in depth the methods of studying vegetational history. The Paleocene, Eocene, and Oligocene epochs are presented completely. A chapter is devoted to the palynological evidence and synthesis. Another section focuses on the xeroseres, hydroseres and related successions. The book can provide useful information to botanists, geologists, students, and researchers.

Book Description
News headlines are forever reporting diseases that take huge tolls on humans, wildlife, domestic animals, and both cultivated and native plants worldwide. These diseases can also completely transform the ecosystems that feed us and provide us with other critical benefits, from flood control to water purification. And yet diseases sometimes serve to maintain the structure and function of the ecosystems on which humans depend. Gathering thirteen essays by forty leading experts who convened at the Cary Conference at the Institute of Ecosystem Studies in 2005, this book develops an integrated framework for understanding where these diseases come from, what ecological factors influence their impacts, and how they in turn influence ecosystem dynamics. It marks the first comprehensive and in-depth exploration of the rich and complex linkages between ecology and disease, and provides conceptual underpinnings to understand and ameliorate epidemics. It also sheds light on the roles that diseases play in ecosystems, bringing vital new insights to landscape management issues in particular. While the ecological context is a key piece of the puzzle, effective control and understanding of diseases requires the interaction of professionals in medicine, epidemiology, veterinary medicine, forestry, agriculture, and ecology. The essential resource on the subject, Infectious Disease Ecology seeks to bridge these fields with an ecological approach that focuses on systems thinking and complex interactions.

Book Description
Students of human behavior have always been interested in the relationship between human populations and their environment. Decades of research not only have illuminated the backdrop against which culture is viewed, but have identi fied many of the conditions that influence or promote technological develop ment, social transformation, and economic reorganization. It has become in creaSingly evident, however, that if we are to explore more forcefully the linkages between culture and environment, a processual orientation is required. This is found in human ecology-the study of the relationship between people and the ecosystem of which they are a part. This book is a collection of papers about the recent and distant past by scientists and humanists involved in the study of human ecology in northeastern North America. The authors critically examine the systemic interface between people and their environment first by identifying the indicators of that rela tionship (e.g., historical documentation, archaeological site patterning, faunal remains), then by defining the processes by which change in one part of the ecosystem affects other parts (e.g., by conSidering how an ecotonal gradient affects biotic communities over time), and finally by explicating the behavioral implications thereof.
