Book Description
Excerpt from The North American Species of Drosophila In View of these facts, it has seemed to the writer that a systematic review of the group would be desirable. No comprehensive study of the American forms has hitherto been made, so that our knowledge of the number of species and of their distribution and habits is very fragmentary. Furthermore, much of the published data on these points is unreliable, for the reason that different names have sometimes been applied to the same form, or different forms have been given the same name. Even when material has been identified by the same entomologist, there is a large possibility of inconsistency - and this applies to the writer's own determinations, for it is very easy to go astray when identifying pinned material. It is hoped, however, that a beginning has been made in the undertaking of bringing order out of something very like chaos.

Book Description
This book facilitates an integrative understanding of the development, genetics and evolution of butterfly wing patterns. To develop a deep and realistic understanding of the diversity and evolution of butterfly wing patterns, it is essential and necessary to approach the problem from various kinds of key research fields such as “evo-devo,” “eco-devo,” ”developmental genetics,” “ecology and adaptation,” “food plants,” and “theoretical modeling.” The past decade-and-a-half has seen a veritable revolution in our understanding of the development, genetics and evolution of butterfly wing patterns. In addition, studies of how environmental and climatic factors affect the expression of color patterns has led to increasingly deeper understanding of the pervasiveness and underlying mechanisms of phenotypic plasticity. In recognition of the great progress in research on the biology, an international meeting titled “Integrative Approach to Understanding the Diversity of Butterfly Wing Patterns (IABP-2016)” was held at Chubu University, Japan in August 2016. This book consists of selected contributions from the meeting. Authors include main active researchers of new findings of corresponding genes as well as world leaders in both experimental and theoretical approaches to wing color patterns. The book provides excellent case studies for graduate and undergraduate classes in evolution, genetics/genomics, developmental biology, ecology, biochemistry, and also theoretical biology, opening the door to a new era in the integrative approach to the analysis of biological problems.

Book Description
Ecological and evolutionary genetics span many disciplines and virtually all levels of biological investigation, from the genetic information itself to the principles governing the complex organization of living things. The ideas and informa tion generated by ecological and evolutionary genetics provide the substance for strong inferences on the origins, changes and patterns of structural and functional organization in bio logical communi ties. It is the coordination of these ideas and thoughts that will provide the answers to many fundamental questions in biology. There is no doubt that Drosophilids provide strong model systems amenable to experimental manipulation and useful for testing pertinent hypotheses in ecological and evolutionary genetics. The chapters in this volume represent efforts to use Drosophila species for such a purpose. The volume consists of a dedication to William B. Heed, followed by four major sections: Ecological Genetics, Habitat Selection, Biochemical Genetics and Molecular Evolution. Each section is introduced by a short statement, and each chapter has an independent summary. The chapters contain the sub stance of talks given at a joint Australia-US workshop held January 5-10, 1989 at the University of New England, New South Wales, Australia. We are indebted to the Division of International Programs of the National Science Foundation (USA) and to the Science and Technology Collaboration Section of the Department of Industry, Technology and Commerce (Australia) for the provi sion of financial support under the US/Australia Science and Technology Agreement.
