Book Description
Iowa's rock record is the product of more than three billion years of geological processes. The state endured multiple episodes of continental glaciation during the Pleistocene Ice Age, and the last glacier retreated from Iowa a mere (geologically speaking) twelve thousand years ago. Prior to that, dozens of seas came and went, leaving behind limestone beds with rich fossil records. Lush coal swamps, salty lagoons, briny basins, enormous alluvial plains, ancient rifts, and rugged Precambrian mountain belts all left their mark. In "Iowa's Geological Past, " Wayne Anderson gives us an up-to-date and well-informed account of the state's vast geological history from the Precambrian through the end of the Great Ice Age. Anderson takes us on a journey backward into time to explore Iowa's rock-and-sediment record. In the distant past, prehistoric Iowa was covered with shallow seas; coniferous forests flourished in areas beyond the continental glaciers; and a wide variety of animals existed, including mastodon, mammoth, musk ox, giant beaver, camel, and giant sloth. The presence of humans can be traced back to the Paleo-Indian interval, 9,500 to 7,500 years ago. Iowa in Paleozoic time experienced numerous coastal plain and shallow marine environments. Early in the Precambrian, Iowa was part of ancient mountain belts in which granite and other rocks were formed well below the earth's surface. The hills and valleys of the Hawkeye State are not everlasting when viewed from the perspective of geologic time. Overall, Iowa's geologic column records an extraordinary transformation over more than three billion years. Wayne Anderson's profusely illustrated volume provides a comprehensive and accessible survey of the state's remarkable geological past.

Book Description
Iowa has more than eighteen thousand archaeological sites, and research in the past few decades has transformed our knowledge of the state's human past. Drawing on the discoveries of many avocational and professional scientists, Lynn Alex describes Iowa's unique archaeological record as well as the challenges faced by today's researchers, armed with innovative techniques for the discovery and recovery of archaeological remains and increasingly refined frameworks for interpretation. The core of this book--which includes many historic photographs and maps as well as numerous new maps and drawings and a generous selection of color photos--explores in detail what archaeologists have learned from studying the state's material remains and their contexts. Examining the projectile points, potsherds, and patterns that make up the archaeological record, Alex describes the nature of the earliest settlements in Iowa, the development of farming cultures, the role of the environment and environmental change, geomorphology and the burial of sites, interaction among native societies, tribal affiliation of early historic groups, and the arrival and impact of Euro-Americans. In a final chapter, she examines the question of stewardship and the protection of Iowa's many archaeological resources.

Book Description
This beautiful and comprehensive guide, many years in the making, is a manual for identifying the butterflies of Iowa as well as 90 percent of the butterflies in the Plains states. It begins by providing information on the natural communities of Iowa, paying special attention to butterfly habitat and distribution. Next come chapters on the history of lepidopteran research in Iowa and on creating butterfly gardens, followed by an intriguing series of questions and issues relevant to the study of butterflies in the state. The second part contains accounts, organized by family, for the 118 species known to occur in Iowa. Each account includes the common and scientific names for each species, its Opler and Warren number, its status in Iowa, adult flight times and number of broods per season, distinguishing features, distribution and habitat, and natural history information such as behavior and food plant preferences. As a special feature of each account, the authors have included questions that illuminate the research and conservation challenges for each species. In the third section, the illustrations, grouped for easier comparison among species, include color photographs of all the adult forms that occur in Iowa. Male and female as well as top and bottom views are shown for most species. The distribution maps indicate in which of Iowa’s ninety-nine counties specimens have been collected; flight times for each species are shown by marking the date of collection for each verified specimen on a yearly calendar. The book ends with a checklist, collection information specific to the photographs, a glossary, references, and an index. The authors’ meticulous attention to detail, stimulating questions for students and researchers, concern for habitat preservation, and joyful appreciation of the natural world make it a valuable and inspiring volume.

Book Description
"Over the course of his 43-year career, James C. Knox conducted seminal research on the geomorphology of the Driftless Area of southwestern Wisconsin. His research covered wide-ranging topics such as long-term land-scape evolution in the Driftless Area; responses of floods to climate change since the last glaciation; processes and timing of floodplain sediment deposition on both small streams and on the Mississippi River; impacts of European settlement on the landscape; and responses of stream systems to land-use changes. This volume presents the state of knowledge of the physical geography and geology of this unglaciated region in the otherwise-glaciated Midwest with contributions written by Knox prior to his passing in 2012 and by a number of his former colleagues and graduate students"--

Book Description
This extensively revised, restructured, and updated edition continues to present an engaging and comprehensive introduction to the subject, exploring the world’s landforms from a broad systems perspective. It covers the basics of Earth surface forms and processes, while reflecting on the latest developments in the field. Fundamentals of Geomorphology begins with a consideration of the nature of geomorphology, process and form, history, and geomorphic systems, and moves on to discuss: structure: structural landforms associated with plate tectonics and those associated with volcanoes, impact craters, and folds, faults, and joints process and form: landforms resulting from, or influenced by, the exogenic agencies of weathering, running water, flowing ice and meltwater, ground ice and frost, the wind, and the sea; landforms developed on limestone; and landscape evolution, a discussion of ancient landforms, including palaeosurfaces, stagnant landscape features, and evolutionary aspects of landscape change. This third edition has been fully updated to include a clearer initial explanation of the nature of geomorphology, of land surface process and form, and of land-surface change over different timescales. The text has been restructured to incorporate information on geomorphic materials and processes at more suitable points in the book. Finally, historical geomorphology has been integrated throughout the text to reflect the importance of history in all aspects of geomorphology. Fundamentals of Geomorphology provides a stimulating and innovative perspective on the key topics and debates within the field of geomorphology. Written in an accessible and lively manner, it includes guides to further reading, chapter summaries, and an extensive glossary of key terms. The book is also illustrated throughout with over 200 informative diagrams and attractive photographs, all in colour.

Book Description
Carbonate rock coasts are found world-wide, from continental shorelines of the Adriatic Sea of Europe to the Yucatan Peninsula of North America, and on tropical islands from Rodrigues Island in the Indian Ocean, to the Mariana Islands in the Pacific Ocean, to the Bahama Islands in the Atlantic Ocean. Such coasts are well known for their unusual and distinctive karst landforms. Karst processes, particularly those associated with coastal landforms, are proving to be surprisingly unique and complex. This volume presents a comprehensive overview of the processes associated with coastal karst development comparing examples from a broad geographical and geomorphological range of island and continental shoreline/paleoshoreline settings, including a review of pseudokarst processes that can compete with and overprint dynamic coastal karst landscapes. As effective management of hydrologic resources grows more complex, coastal caves and karst represent fundamental components in associated coastal aquifers, which in the rock record can also form significant petroleum reservoirs. Audience By providing a clearer understanding of the geological, biological, archaeological and cultural value of coastal caves and karst resources, this volume offers a critical tool to coastal researchers and geoscientists in related fields and to coastal land managers as it illustrates the diversity of coastal karst landforms, the unique processes which formed them, the diversity of resources they harbor and their relationship to coastal zone preservation strategies and the development of sustainable management approaches.

Book Description
In The Emerald Horizon, Cornelia Mutel combines lyrical writing with meticulous scientific research to portray the environmental past, present, and future of Iowa. In doing so, she ties all of Iowa's natural features into one comprehensive whole. Since so much of the tallgrass state has been transformed into an agricultural landscape, Mutel focuses on understanding today’s natural environment by understanding yesterday’s changes. After summarizing the geological, archaeological, and ecological features that shaped Iowa’s modern landscape, she recreates the once-wild native communities that existed prior to Euroamerican settlement. Next she examines the dramatic changes that overtook native plant and animal communities as Iowa’s prairies, woodlands, and wetlands were transformed. Finally she presents realistic techniques for restoring native species and ecological processes as well as a broad variety of ways in which Iowans can reconnect with the natural world. Throughout, in addition to the many illustrations commissioned for this book, she offers careful scientific exposition, a strong sense of respect for the land, and encouragement to protect the future by learning from the past. The “emerald prairie” that “gleamed and shone to the horizon’s edge,” as botanist Thomas Macbride described it in 1895, has vanished. Cornelia Mutel’s passionate dedication to restoring this damaged landscape—and by extension the transformed landscape of the entire Corn Belt—invigorates her blend of natural history and human history. Believing that citizens who are knowledgeable about native species, communities, and ecological processes will better care for them, she gives us hope—and sound suggestions—for the future.
