Mathematical Modeling in Biology

Shandelle M. Henson is Professor of Mathematics and Professor of Ecology at Andrews University, Michigan, USA. She uses dynamical systems theory and bifurcation theory to study nonlinear population dynamics and the effects of climate change on marine organisms. Shandelle earned a Ph.D. in mathematics at the University of Tennessee, Knoxville and did several years of postdoctoral work at the University of Arizona. She serves as editor-in-chief of the journal Natural Resource Modeling and is a coauthor of the book Chaos in Ecology: Experimental Nonlinear Dynamics (Academic Press 2003) which documented chaotic dynamics in laboratory populations of insects.James L. Hayward is Professor Emeritus of Biology at Andrews University, Michigan, USA. He earned a Ph.D. in zoology from Washington State University, and he has studied the behaviors and population dynamics of marine birds and mammals in the Pacific Northwest of North America since he began graduate studies in 1972. In addition, Jim has studied the behavior of marine iguanas and flightless cormorants on the remote and uninhabited island of Fernandina, the westernmost island in the Galapagos. He also is a recognized expert in the fossilization of eggshell in birds and dinosaurs.Shandelle and Jim, a wife-husband research team, are widely published in both the technical and popular literature, and both have won awards for their teaching. They have applied mathematical methods to the behavioral dynamics of seabirds at Protection Island National Wildlife Refuge in the Strait of Juan de Fuca, Washington, USA since 2002. They reside in Niles, Michigan, USA and they have a daughter, son-in-law, and four grandsons. They enjoy hiking, geology, art, music, and literature.

"Without hesitation, we highly recommend this book for Mathematics and Science Undergraduate Students and Graduate-Level Biology Students as well as researchers who are interested in biological research using a Mathematical Modeling approach. Apart from providing information for readers, this book is also equipped with exercises in almost every chapter to train readers to understand the contents of the book and this book is also equipped with various case studies that can be studied to understand the concepts of Mathematical Modeling in Biology. We greatly appreciate the authors who have contributed to writing this book which is the first edition of CRC Press for the Mathematical Biology Series. The enormous potential of Mathematical Modeling as a statistical approach in research methods can be predicted that this book will become a fundamental need for current and future research in the field of biology and several related fields."- Technometrics
