Native Trees of the Midwest is a definitive guide to identifying trees in Indiana and surrounding states, written by three leading forestry experts. Descriptive text explains how to identify every species in any season and color photographs show all important characteristics. Not only does the book allow the user to identify trees and learn of their ecological and distributional attributes, but it also presents an evaluation of each species relative to its potential ornamental value for those interested in landscaping. Since tree species have diverse values to wildlife, an evaluation of wildlife uses is presented with a degree of detail available nowhere else. The revised and expanded second edition contains a chapter on introduced species that have become naturalized and invasive throughout the region. All accounts have been reviewed and modifications made when necessary to reflect changes in taxonomy, status, or wildlife uses. Keys have been modified to incorporate introduced species.   An interview with the authors is available on YouTube.
Photographing Turkey Run: A Guide to Nature Photography was written to be used in conjunction with Daniel P. Shepardson’s A Place Called Turkey Run: A Celebration of Indiana’s Second State Park in Photographs and Words. This guide contains tips and techniques designed to provide a basic understanding of how to photograph nature and improve one’s photography skills.    
A biochemist and an agronomist present the known facts - for the first time in one volume - about guar, an Old World legume. Guar is now grown in large quantities to produce guar gum, an important industrial water-soluble hydrocolloid. Guar seed has a high content of vegetable protein, and with genetic improvement, it could provide a valuable source of protein in the human diet. The guar plant has been cultivated in India and Pakistan for generations, and guar gum has been used in manufacturing in the United States and abroad since World War 11. Although some investigation has been made into the potential of guar seed as a valuable source of protein for the human diet, more research is required to make use of guar seed economically feasible.
A recent history of plant science, this compilation of lectures was initially presented at the 1991 Plant Science Lecture Series, sponsored by Iowa State University. The eight scholars featured are key contributors to plant science over the past 50 years.   Scientists often get so engrossed in the day-to-day and month-to-month activities of their research programs and professional endeavors that they fail to record and interpret the chronology of events that lead to great scientific discoveries and advances in using science for the benefit of humankind. Iowa State University, through the sponsorship of the Department of Agronomy, Botany, Forestry, Horticulture, and Plant Pathology, presents an annual Plant Science Lecture Series, which provides the opportunity for outstanding scholars to share their knowledge and expertise in an atmosphere of intellectual camaraderie.   Historical Perspectives in Plant Science is a compilation of the 1991 lectures presented for the series and provides a unique look at plant science history via anecdotes and personal knowledge about research failures and successes, cooperation and competition among scientists, and the interplay of discoveries in the several disciplines encompassed by the field of plant science. It provides a benchmark, as of 1991, for the history of plant science as seen, experienced, and interpreted by eight scholars who played significant roles in "making plant science history."   The areas of research covered range from a general overview of plant science to the development of the history of plant physiology, plant pathology, quantitative genetics, and cytogenetics to molecular biology to the history of plant breeding methology and accomplishments.
