Open SUNY Textbooks: Microbiology: A Laboratory Experience

Open SUNY Textbooks:
Microbiology: A Laboratory Experience

From OpenStax:
"Designed to support a course in microbiology, Microbiology: A Laboratory Experience permits a glimpse into both the good and the bad in the microscopic world. The laboratory experiences are designed to engage and support student interest in microbiology as a topic, field of study, and career.

This text provides a series of laboratory exercises compatible with a one-semester undergraduate microbiology or bacteriology course with a three- or four-hour lab period that meets once or twice a week. The design of the lab manual conforms to the American Society for Microbiology curriculum guidelines and takes a ground-up approach — beginning with an introduction to biosafety and containment practices and how to work with biological hazards. From there the course moves to basic but essential microscopy skills, aseptic technique and culture methods, and builds to include more advanced lab techniques. The exercises incorporate a semester-long investigative laboratory project designed to promote the sense of discovery and encourage student engagement. "

Introduction to Computational Biology: An Evolutionary Approach

From the About:
"This introduction to computational biology is centered on the analysis of molecular sequence data. There are two closely connected aspects to biological sequences: (i) their relative position in the space of all other sequences, and (ii) their movement through this sequence space in evolutionary time. Accordingly, the first part of the book deals with classical methods of sequence analysis: pairwise alignment, exact string matching, multiple alignment, and hidden Markov models. In the second part evolutionary time takes center stage and phylogenetic reconstruction, the analysis of sequence variation, and the dynamics of genes in populations are explained in detail. In addition, the book contains a computer program with a graphical user interface that allows the reader to experiment with a number of key concepts developed by the authors.

Introduction to Computational Biology is intended for students enrolled in courses in computational biology or bioinformatics as well as for molecular biologists, mathematicians, and computer scientists."

Anatomy and Physiology

From the Summary:
"Anatomy and Physiology is a dynamic textbook for the two-semester human anatomy and physiology course for life science and allied health majors.

The web-based version of Anatomy and Physiology also features links to surgical videos, histology, and interactive diagrams."

Cell and Molecular Biology 3E: What We Know and How We Found Out

From the Summary:
"The 3rd edition of Cell and Molecular Biology 3e: What We Know & How We Found Out (CMB3e) is the latest edition of an interactive Open Educational Resource (OER) electronic textbook, available under a Creative Commons CC-BY license. Like earlier editions (and like most introductory science textbooks), the third edition of the CMB3e iText opens with a discussion of scientific method. CMB3e retains its focus on experimental support for what we know about cell and molecular biology. Having a sense of how science is practiced and how investigators think about experimental results is essential to understanding the relationship of cell structure and function, not to mention the natural world around us.

Instructors and students can freely download the CMB3e Sample Chapter, Basic CMB3e and Annotated CMB3e iText. Instructors can request the Instructors CMB3e iText. All iText users can create their own digital annotations or download and print the text and write in the margins the old-fashioned way!"

Organic Chemistry with a Biological Emphasis Volume I

From the Summary:
"The traditional approach to teaching Organic Chemistry, taken by most of the textbooks that are currently available, is to focus primarily on the reactions of laboratory synthesis, with much less discussion - in the central chapters, at least - of biological molecules and reactions. This is despite the fact that, in many classrooms, a majority of students are majoring in Biology or Health Sciences rather than in Chemistry, and are presumably taking the course in order to learn about the chemistry that takes place in living things.

In an effort to address this disconnect, I have developed a textbook for a two-semester, sophomore-level course in Organic Chemistry in which biological chemistry takes center stage. For the most part, the text covers the core concepts of organic structure, structure determination, and reactivity in the standard order. What is different is the context: biological chemistry is fully integrated into the explanation of central principles, and as much as possible the in-chapter and end-of-chapter problems are taken from the biochemical literature. Many laboratory synthesis reactions are also covered, generally in parallel with their biochemical counterparts - but it is intentionally the biological chemistry that comes first."

Human Biology

From the Summary:
"This textbook has been created with several goals in mind: accessibility, customization, and student engagement—all while encouraging students toward high levels of academic scholarship. Students will find that this textbook offers a strong introduction to human biology in an accessible format."

Evolutionary Biology

Evolutionary Biology

From the Description:
"Now in an exciting new journal format, Evolutionary Biology is dedicated to the view that evolutionary theory is a unifying framework for the biosciences. The journal is a forum in which critical reviews, original research, commentaries, and controversial views are brought together to contribute to greater understanding of the origins and diversity of life.
This vision reflects the original intent of the serial publication Evolutionary Biology, first published in 1967 as a forum in which some of the most important papers in Evolutionary Biology appeared. The topics varied greatly and many of the papers were synthetic in nature. Although some existing journals deal with various facets of evolutionary biology, Evolutionary Biology fills the need for a journal which remains true to the vision and intent laid out by Dobzhansky et al. but that is adapted to today's publication environment. Evolutionary Biology provides a focal point for broad syntheses, in-depth treatment and controversial ideas."
