OER for COS

This open textbook covers the most salient environmental issues, from a biological perspective. The text is designed for an introductory-level college science course. Topics include the fundamentals of ecology, biodiversity, pollution, climate change, food production, and human population growth.

This text is intended to support courses that bridge the divide between mathematics typically encountered in U.S. high school curricula and the practical problems that natural resource students might engage with in their disciplinary coursework and professional internships.

This course uses the basic principles of biology and earth science as a context for understanding environmental policies and resource management practices. Our planet is facing unprecedented environmental challenges, from oil spills to global climate change. In ENSC 1000, you will learn about the science behind these problems; preparing you to make an informed, invaluable contribution to Earth's future. I hope that each of you is engaged by the material presented and participates fully in the search for, acquisition of, and sharing of information within our class.

The Soils Laboratory Manual, K-State Edition is designed for students in undergraduate, introductory soil science courses, and highlights the many aspects of soil science, including: soil genesis and classification, soil physical properties, soil-water interaction, soil biology, soil chemistry, and soil fertility. The lab manual includes 15 different laboratories, each one starting with an introduction and pre-lab assignment, followed by in-lab activities, and complimented by post-lab assignment. In-lab activities involve field trips, experiments, observation stations, or problem sets. Post-lab assignments include online quizzes, problem sets, or laboratory summary reports.The Soils Laboratory Manual, K-State Edition is used in Kansas State University's AGRON 305 class, and is based on the Soils Laboratory Manual, NC State Edition used in North Carolina State University's SSC 201 class. The Soils Laboratory Manual, K-State Edition was originally published as a supplement to 'An Open-Source Laboratory Manual for Introductory Undergraduate Soil Science Courses' in Natural Sciences Education, Vol. 46:170013, and is also available for download at https://dl.sciencesocieties.org/publications/nse/articles/46/1/170013. Supporting materials, assignments, instructor versions, and DOCX and RTF files of the lab manual are available at http://open.soilscience.info.

Quantitative Ecology introduces and discusses the principles of ecology from populations to ecosystems including human populations, disease, exotic organisms, habitat fragmentation, biodiversity and global dynamics. The book also reformulates and unifies ecological equations making them more accessible to the reader and easier to teach.
