Preface

Welcome to “Molecular Ecology & Evolution,” an open educational resource (OER) textbook designed for advanced undergraduate students in biology and related fields. This textbook is the result of funding by the Wheaton’s Library, Technology and Learning Committee (LTLC) to provide a resource for understanding the complex interplay between molecular biology and ecology. The material presented in this textbook aligns with the curriculum of the Molecular Ecology & Evolution course (BIO 317 and BIO 317L), taught at Wheaton College, and aims to bridge the gap between theoretical concepts and practical applications in this fascinating field of study. Molecular ecology is an interdisciplinary field that combines molecular biology, genetics, and ecology to unravel the mysteries of biodiversity and the evolutionary processes that shape it. This textbook serves as an introduction to the core concepts and methodologies of molecular ecology, offering insights into topics such as molecular markers, population genetics, phylogeography, and conservation genetics. The book is designed to cater to Biology majors who have only completed an introductory level Biology course but are eager eager to explore the molecular mechanisms underlying ecological interactions and evolutionary patterns. The content was deliberately designed in such a way that each chapter is short and tailored to the specific lecture and lab material explored each week. It was not meant to be exhaustive, with the more in-depth details to be presented in lecture and lab. For those adopting this resource, I suggest assigning the readings to students prior to coming to class, which can then be used as material for pre-lecture quizzes. Students are encouraged to engage with the material through discussions, hands-on laboratory exercises, and projects. The textbook is complemented by laboratory exercises that provide practical experience with key techniques, including DNA extraction, PCR, and bioinformatics analysis. The course also culminates in two major projects: an NSF-style research proposal and a manuscript for publication, allowing students to apply their knowledge creatively and collaboratively. Pre-requisites: BIO 114 (Introductory Biology) and any 200-level course.

Molecular Ecology & Evolution is designed to be a dynamic and evolving resource, reflective of the ever-changing field it represents. We hope that this textbook serves as a valuable guide for students embarking on their journey into the world of molecular ecology, fostering a deeper understanding and appreciation of the natural world.
