Book Description
From windswept tundra to humid subtropical everglades, fromgracious coniferous forests to austere deserts, North America isblessed with an incredibly diverse array of natural environments,each supporting a unique system of plant and animal life. Thesesystems--also known as biomes--are tightly woven webs of life thathave taken millennia to evolve. This lavishly illustrated bookintroduces readers to this extraordinary array of naturalcommunities and to the subtle interactions of minerals, plants, andanimals that take place within them. Professor Eric Bolen takes a qualitative, intuitive approach to hissubject, beginning with an overview of essential ecological termsand concepts, such as competitive exclusion, taxa, niches, andsuccession. Then, biome by biome, he covers the entirety of Canadaand the United States, starting with the tundra of the far northand working his way south and then west to conclude in the desertsand chaparral of southern California. Along the way, he delves intopertinent conservation issues and features fascinating historicalvignettes and original documents detailing human impact on variousenvironments--for instance, the role of John Deere's plow insettling grasslands, and the use of fur records from Hudson's BayCompany. Throughout, he enlivens the text with dozens of exquisitephotographs and illuminating maps, graphs, charts, andtables. Ecology of North America is an ideal first text for studentsinterested in natural resources, environmental science, andbiology, and it is a useful and attractive addition to the libraryof anyone interested in understanding and protecting the naturalenvironment.

Book Description
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.

Book Description
FOREST ECOLOGY Authoritative resource covering traditional plant ecology topics and contemporary components such as climate change, invasive species, ecosystem services, and more Forest Ecology provides comprehensive coverage of the field, focusing on traditional plant ecology topics of tree structure and growth, regeneration, effects of light and temperature on tree physiology, forest communities, succession, and diversity. The work also reviews abiotic factors of light, temperature, physiography (landforms and topography), soil, and disturbance (especially fire), and provides coverage of ecosystem-level topics including carbon storage and balance, nutrient cycling, and forest ecosystem productivity. The 5th edition of Forest Ecology retains the readability and accessibility of the previous editions and includes important additional topical material that has surfaced in the field. All topics are approached with a landscape ecosystem or geo-ecological view, which places biota (organisms and communities) in context as integral parts of whole ecosystems that also include air (atmosphere and climate), topography, soil, and water. As such, the book fills a niche utilized by no other forest ecology text on the market, helping students and researchers consider whole ecosystems at multiple scales. Sample topics covered in Forest Ecology include: Contemporary components of forest ecology, including climate change, invasive species, diversity, ecological forestry, landscape ecology, and ecosystem services. Characteristics of physiography important for forest ecosystems, including its effects on microclimate, disturbance, soil, and vegetation. Genetic diversity of woody plants and genecological differentiation of tree species, including the importance of hybridization, polyploidy, and epigenetics. Site quality estimation using tree height and ground flora, and multiple-factor approaches to forest site and ecosystem classification and mapping. Forest Ecology is a highly accessible text for students, but it also serves as an excellent reference for academics. In addition, practitioners of forest ecology can also harness the information within to gain better insight into the field for practical application of concepts.

Book Description
Biology textbooks and books on the history of science generally give a limited picture of the roles women have played in the growth and development of the biological sciences, mentioning primarily the Nobel laureates. This book provides a definitive archival collection of essays on a larger group of women, profiling both their work and their lives. The volume includes 65 representative women from different countries and eras, and from as many branches of biological investigation as possible. In addition to biographical information and an evaluation of the woman's career and significance, each entry provides a full bibliographic listing of works by and about the subject. The volume includes entries on women who have gained recognition through attainment of advanced degrees despite familial and societal pressures, innovative research results, influence exerted in teaching and guidance of students, active participation and leadership in professional societies, extensive scholarly publication, participation on journal editorial boards, extensive field experience, and influence on public and political scientific policymaking. A woman was considered eligible for inclusion if she met several of these criteria. Providing a historical perspective, the book is limited to women who were born before 1930 or are deceased.

Book Description
The Background of Ecology is a critical and up-to-date review of the origins and development of ecology, with emphasis on the major concepts and theories shared in the ecological traditions of plant and animal ecology, limnology, and oceanography. The work traces developments in each of these somewhat isolated areas and identifies, where possible, parallels or convergences among them. Dr McIntosh describes how ecology emerged as a science in the context of nineteenth-century natural history.

Book Description
The prairie grassland biome covers the heartland of North America with an eastward extension called the Prairie Peninsula. Primarily composed of tallgrass prairie, this biome lies between the shortgrass prairies of the west and the eastern deciduous forest region and includes the states of Illinois, Indiana, southeastern Wisconsin, and Ohio. With text by coauthors Gary Meszaros and Guy L. Denny and striking photographs by Meszaros, The Prairie Peninsula examines the many prairie types, floristic composition, and animals that are part of this ecosystem. It took only 50 years for 150 million acres of tallgrass prairie to disappear under the steel plow, transforming the Prairie Peninsula into fields of corn and wheat. Today, only a few thousand acres of this endangered ecosystem remain in small parcels, some just a few acres each. The second half of the 19th century brought the mass slaughter of prairie wildlife. By 1900, like the prairie they roamed, the plains bison, gray wolf, and eastern elk became extirpated east of the Mississippi River. The Prairie Peninsula also tells the story of the early settlers and the hardships they endured. Thousands died of milk sickness and malaria, with prairie fires sending flames 30 feet into the air and stretched across the horizon, destroying everything in their path. Today, many of these pioneers lie buried in cemeteries comprising prairie remnants, fragments of the primeval land they tried to tame. The authors investigate these and other surviving prairie remnants and current efforts to save these traces of original North American grassland. Both Gary Meszaros and Guy L. Denny have traveled extensively throughout the Midwest, studying the animal and floristic composition of original prairie remnants.
