This text has been compiled to provide an overview of how plant breeders develop cultivars of plant species. The methods that breeders use depend directly on the type of cultivar used to produce a commercial crop. The four most common types of cultivars are (a) clonal cultivars (b) synthetic cultivars (c) pure-line cultivars and (d) hybrid cultivars. These types of cultivars will be discussed throughout the book, alongside review questions for self-study.
This resource will explore the validity of arguments and/or conclusions in dinosaur research through evaluating the scientific evidence. Students using this resource will read, experiment, and evaluate scientific literature surrounding dinosaurs. Students will have the opportunity to work with others to evaluate the plausibility of the dinosaur concepts and theories, and engage in hands-on experiments to add additional information to their interpretations. Students will learn to participate in evaluation mechanisms to assess critical thinking and science literacy.
This book presents the original works of Environmental Justice students from Linn-Benton Community College. Students select and design projects based on their experiences and interests to contribute to this living anthology each term. The goal of this publication is to increase the impact of student scholarship, research, creativity, and activism to work for environmental and social justice in our communities. These openly-licensed works span multiple formats and genres based on student interest.
Principles of Cultivar Development is intended to help you learn how to be a successful manager of a cultivar development program. In this text, you will apply the principles learned in Plant Breeding Methods to design a breeding program that makes effective use of available resources and alternative breeding strategies. By the end of this volume, readers will be able to describe the process for developing clonal, pure-line, hybrid, and synthetic cultivars. Each chapter includes additional readings and examples of how breeders have implemented the concepts in their breeding programs.

Introducción a la Química Ambiental nos invita a entender cómo los principios químicos influyen en nuestro entorno y qué podemos hacer para cuidarlo. Este libro explora el impacto de nuestras actividades en el aire, el agua y el suelo, explicando las reacciones químicas detrás de estos problemas. Pero no se queda ahí: también nos muestra cómo la química puede ser una aliada en el desarrollo de tecnologías limpias y soluciones sostenibles que ayuden a contrarrestar los efectos negativos de la industrialización y el crecimiento poblacional. Además, propone reflexionar sobre nuestro papel en la protección del planeta. Con apartados clave como "Componentes del Sistema Ambiental", es una herramienta esencial para ingenieros y personas interesadas en comprender cómo interactúan los sistemas naturales y humanos, inspirando a buscar soluciones prácticas y sostenibles para los desafíos ambientales actuales.
This textbook is oriented toward a first or second year college science class, or an advanced high school course. Sixteen chapters are present which fits a 16-week college semester. These chapters may be divided into three sections:
Environmental Geology is a comprehensive, up-to-date textbook for college-level courses on the environmental aspects of Earth Science. It covers Earth systems, climate change, glaciation, natural hazards like earthquakes and floods, and essential resources such as water, energy, and metals. Richly illustrated with embedded exercises—some interactive—it engages students as they explore key geological processes and their environmental impacts.
