Microorganisms are the most abundant form of life on Earth and in recent decades it has become increasingly clear that their collective activities are one of the dominant forces shaping the Earth.
Biological psychology is the study of the biological bases of behavior and mental processes. It explores how biological factors like genes, hormones, neurotransmitters, and brain structures influence psychological components like thoughts, emotions, memories, and actions. This free and open textbook provides a wide ranging and up-to-date introduction to the main topics and methods of biological psychology.
This resource is intended for an introductory or intermediate-level college genetics course. It begins with an exploration of DNA and genome structure and continues with a study of the molecular mechanisms that drive gene expression. Concepts of classical transmission genetics are linked to the molecular mechanisms that underlie observable phenotypes. It concludes with specific topics that synthesize information from both molecular and transmission genetics, including consideration of topics like epigenetics, cancer biology, and evolution. Examples of both historical and current problems in genetics are presented, along with conversations of the relationship between genetics and society.
This laboratory manual is meant to be used in a lab course that accompanies a college-level introductory human anatomy course. It covers the language of anatomy, cells and tissues, and the organ systems that comprise the human body. Multiple open textbooks were adapted to create this lab manual. Attribution for these sources are provided at the end of each chapter.
Understanding organisms—their evolution, ecology and body systems— is at the heart of this free and open resource geared toward introductory-level college biology majors. This text has been adapted and curated with a lens toward representation and inclusivity. Student engagement is encouraged through ample graphics, embedded media and linked supplementary resources throughout, as well as interactive, responsive H5P practice activities.
This book is aimed at fellow academics teaching biosciences students (probably in the first or second year of an undergraduate degree). It contains materials from eight different sets of practicals that colleagues have developed here at the University of Sheffield, concerning different areas of molecular and cellular biology. The experiments all span a few lab sessions, and are a step away from “cookbook” style labs with defined instructions and a certain outcome; each one contains significant elements of experimental planning. The standard lab session in our School is three hours long, with students working in pairs.

Introduction to Behavioral Neuroscience aligns to the topics and objectives of introductory behavioral neuroscience courses taught in psychology, biology, neuroscience, and similar departments. This offering is intended for undergraduates with no presumed college-level science coursework, and presents the foundational principles of brain-behavior-environment interactions.
An overview of the study of human behavior through a biological lens, this text focuses on the role of the central nervous system and its role in the regulation and control of human behavior. Topics include both structure and function of neurons, neurophysiology of the nervous system, basic neuroanatomy, drugs and behavior, internal regulatory processes, learning and memory, emotions, and some forms of psychopathology.
Microbes form the “unseen majority” of life on Earth, with bacteria at the forefront as both the architects of life’s chemical foundations and agents of disease. But their story is far more complex. Bacteria thrive in diverse and extreme environments, driven by the dynamic evolution of their genomes. These tiny organisms wield an extraordinary ability to adapt, balancing genetic changes across generations with rapid physiological responses to environmental shifts. In Bacterial Genomes, the evolutionary and regulatory processes that shape bacterial life are brought to life. This textbook offers a conceptual exploration of how bacterial genomes are organized, how they evolve, and how their genetic information is interpreted through intricate molecular networks. Drawing on both cutting-edge research and the historical milestones that shaped microbiology, it illuminates how bacteria navigate the intersection of genetic adaptation and ecological resilience. Designed for college students, interdisciplinary researchers, and even the determined amateur, Aswin Seshasayee moves beyond technical jargon to provide a thought-provoking synthesis of bacterial evolution and adaptation. Unlike traditional genomics texts, this book blends historical insights with contemporary discoveries, offering a fresh perspective on the role of bacteria in shaping the living world.
Introduction to Microbiology is a textbook designed for non-majors and allied health microbiology courses. The book features chunked content, embedded assessments, and clearly stated learning objectives to support active and inclusive learning. It incorporates equity-focused case studies, interactive elements, and diverse global perspectives to enhance engagement and representation - reflecting our belief that students are not only learners but also co-creators of knowledge. Created by Ying Liu of City College of San Francisco (CCSF) in collaboration with undergraduate students from CCSF and the University of Dundee.
