Crop Adaptation and Improvement for Drought-Prone Environments
Ndjido Kane; Daniel Foncéka; Timothy Dalton · New Prairie Press · 2022
This book focuses on three important elements in the development of cereal and legume crops in semi-arid West Africa. The first section illustrates the socioeconomic factors that affect the food system for these crops and contains an overview of crop production and consumption in the region. Then, important inputs that affect system productivity are presented: preferences for new seed varieties, yield response to fertilizer, counterfeit herbicides, climate information, and the way farmers develop expectations about the weather events that shape cropping outcomes. The final chapter of section one is dedicated to understanding urban consumer preferences for processed food products derived from pearl millet. The second section addresses the state of the art of phenotyping and the modeling of crop adaptation to dryland farming systems. Chapters in section two focus on the regional network for phenotyping, high throughput phenotyping in field situations, root architectures, and crop ideotypes. In addition, empirical evidence is presented on root and soil interactions and the effectiveness of unmanned aerial vehicles (UAVs to assess sorghum physiology. Finally, the third section investigates the genetic diversity and improvement of dryland crops. Chapters in this section focus on biodiversity and agricultural system sustainability, orphan crops such as fonio, and the utilization of a regional germplasm collection in the improvement of cowpea, groundnut, pearl millet, and sorghum.

Climate Justice in Your Classroom
Alexandra Anderson-Frey; Brittany Johnson; Mikelle Nuwer; Luanne Thompson · University of Washington · 2023
As the inequitable impacts of climate change become more evident and destructive, it is essential for climate and environmental justice, as well as methods of civic engagement, to be taught at a high-level to college-level students. This book provides real examples of how professors at the University of Washington integrated these critical issues into their teachings, both in targeted lessons and as throughlines across an entire course. These samples of how environmental and climate justice have been successfully integrated into higher-level education can serve as both a record of the UW's progress towards centering JEDI at the heart of all students, and as a model for future instructors to use as they work to incorporate more aspects of justice and engagement into their own material.

Fish, Fishing, and Conservation
Donald Orth · Virginia Tech Publishing · 2023
Fish, Fishing, and Conservation is a 389-page, peer-reviewed open textbook intended for undergraduate students who are exploring majors in Fish & Wildlife. It is also relevant to a general audience or for use in courses which explore social and ethical aspects of fish, fishing and conservation. People, places, and approaches to fishing are as varied as the diverse fish fauna that exist on the planet. As conservation planners recognize the value of substantial engagement of stakeholders in decision making and ineffectiveness of rigid top-down management approaches, Fish, Fishing, and Conservation asserts that all peoples must play a role in conservation. Through case studies, engaging narrative and graphics, and exercises, the text explores major motivations for fishing and non-fishing related values, responsible fisheries practices, the rights of all people to decide how to manage and conserve fish, their habitats, and how they are utilized in the context of overfishing as a pressing global problem for which appropriate solutions are not easily found nor implemented. Introductory chapters examine fish, fishing, and why fish matter and examine the role of values in driving conservation initiatives. Fish and their unique sensory capabilities are described along with a review of recent studies to examine issues of pain, sentience, and learning in fishes living in a foreign, underwater world. The text incorporates these new findings in conservation and management leading readers to evaluate and adopt suitable approaches to ethical reasoning which consider the welfare needs of wild and cultured fishes. Later chapters focus on the role of gender in fishing, conservation organizations, recreational fishing, and a focus on specific fisheries that reveal the principles of conservation and management as they play out in major controversies. Additionally, the textbook contains audio recordings of professional profiles by Virginia Tech students. These are linked at the beginnin

Threshold Concepts in Biochemistry
Julian Pakay; Hendrika Duivenvoorden; Thomas Shafee; Kaitlin Clarke · La Trobe University · 2023
Biochemistry (and Molecular Biology) represent one of the fastest-growing fields of scientific research and technical innovation and the resulting biotechnology is increasingly applied to other fields of study. So, an understanding of Biochemistry is increasingly important for students in all biological disciplines. However, at the same time, the content is inherently complex, highly abstract, and often deeply rooted in the pure sciences – mathematics, chemistry, and physics. This makes it difficult to both learn and to teach. This book is designed as a succinct and focused resource, specifically aimed to help students grasp key threshold concepts in Biochemistry. Due to their troublesome nature, understanding threshold concepts is a cognitively demanding task. By using a series of thematically linked case studies that accompany theory, the cognitive load will be reduced. This will free up students to focus on learning concepts rather than distracting them with unnecessary specifics.
