"Botany in Hawai‘i" discusses introductory topics of Botany through examples of the native and introduced plants found in Hawai‘i. It includes anatomy and physiology of seeds, roots, leaves, stems, fruits and flowers and covers the main plant groups from nonvascular to flowering plants. This book provides a visual reference to botanical concepts and terminology for beginners.
In The Botany of Desire, Michael Pollan explores risks inherent in one of the most widespread practices in modern agriculture. It's called monoculture, and it refers to cultivation of single or very similar varieties of a food crop on large acreages. In many cases, the variety is one that dominates the marketplace, like the Russet Burbank potato, whose shape makes it a favorite for cutting French fries, or one of the few apple varieties commonly seen in supermarkets. Monoculture may offer economic advantages, but Pollan argues that it brings serious environmental risks.
A knowledge of broadleaf plant parts will help the student identify plants at various stages of life. The weed ID resource books often use technical terms to describe how the plant parts look. It is important the student understands the technical terms in order to properly identify weed species. Students will also practice using common weed id apps
This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public.

"Tropical maize hybrid, a single cross of flint and dent inbred lines, is an important crop throughout the Americas and Africa. Crop yield, however, is highly dependent on nitrogen availability, and fertilizers are therefore often necessary to increase production. Developing more nitrogen-efficient maize would not only cut costs for farmers, it would also increase crop yield and reduce environmental impacts. But how do you make a plant more nitrogen efficient? The performance and production of crops can be improved by selectively crossing individuals with desired traits. When such plants are crossed, they produce hybrids that are often bigger, stronger, and more vigorous than either of the parent plants. By carefully choosing which individuals are used in creating these hybrids, specific traits, such as nitrogen efficiency, can be selected for..."

This resource is a publishing of 64 drawn illustrations. The images were initially created for an art installation by Kellie Bornhoft (kelliebornhoft.com). The artist wishes to share the images under CC BY-NC 4.0 for educational and non-commercial use. The intention is to bring awareness to these endangered species.

"Walking through the produce section at the grocery store, you are likely to find tomatoes of all shapes, sizes, and colors. One variety may be large and oblong with a hint of bitter flavor while another will have small, sweet fruits. This variance is primarily the result of genetic and chemical properties of the different varieties. But it turns out, environment also plays a role. A team of Italian scientists has shown that the molecular properties of tomatoes are strongly influenced by environmental factors such as temperature and moisture. And changing these factors can, in turn, have pronounced effects on the physical and culinary qualities of the fruits – an important finding considering the pace of current climate change. To tease apart the interaction between genetics, environment, and organoleptic traits, the research team grew three tomato varieties in two different locations. This exposed the plants to varying levels of moisture, soil acidity, and temperature, among other conditions..."

This transect across northern Washington State was one of our most geologically and biologically diverse field trips. The trip started with a drive across the relatively uniform basalt flows of the Columbia plateau and then traversed the extremely geologically complex North Cascades accessible from a scenic route through the small, and relatively less-traveled, North Cascades National Park. Steep gradients in elevation annual precipitation and winter temperatures revealed equally dramatic changes in vegetation from cold desert shrub lands to temperate coastal rain forests. Like previous trips, this one allowed students to observe glacial processes up close and trace the history of plant succession as glaciers retreat.

This eBook aims to support current and future plant genetic resource managers as they consider the impacts of climate change on plants, agriculture, agrobiodiversity, and plant collections. Our goal is to provide information for readers to learn, understand, plan, and anticipate climate change extremes and how they might impact plant conservation and ex situ collections. Developing plans and preparing management and decision-making processes for dealing with the effects of climate change aligns with many sustainability practices and brings forward skills and techniques for forecasting and adaptive resource management.
In this eBook, we focus on introducing broad ideas, tools, and tactics to support ex situ plant collection managers in building climate-ready collections. We summarize the impacts of climate change on agriculture and food systems, and present a series of chapters that highlight important considerations of a complex landscape, including:
Chapter 1 – Understanding how climate changes impacts agriculture and food systems
Chapter 2 – Identifying the importance of plants in both mitigating and adapting to climate change
Chapter 3 – Understanding the need and value of ex situ plant collections for providing solutions that address the effects of climate change
Chapter 4 – Understanding how climate change affects plant interactions with pollinators, pathogens, and pests
Chapter 5 – Describing methods and opportunities for plant breeding to respond to climate change
Chapter 6 – Considering climate change impacts on plant collections management
Chapter 7 – Learning to develop plans that address the vulnerabilities of climate change
This information serves as an overview of a complex subject that includes the impacts of climate change on agricultural productivity and the critical roles that plant collections have in mitigating and adapting to a changing climate. A greater understanding of these key topics will provide critical insights into the planning necessary to ensure that food plant genetic resources are conserved for current and future generations.

The goal of this class was to explore the natural history of the southern part of the Cascade Range in Oregon. We discussed the complex geologic setting of the range and focused primarily on volcanic features, geologic history and landscape evolution. Adaptation of organisms to desert, alpine and forest habitats were investigated, as well as the spatial and temporal factors that influenced plant species distribution. We spent most of our time exploring Crater Lake National Park and Newberry Volcano National Monument during this immersive field experience..
