Explorers' botanical notebook : in the footsteps of Theophrastus, Marco Polo, Linnaeus, Flinders, Darwin, Speke and Hooker
\"This book follows the journey of over 80 pioneering botanists and the important findings and collections they have made. It includes each journey and routes taken with the help of maps and personal notes. Each story explains the complications and difficulties that each botanist had to overcome but the many discoveries made along the way.\"-- Provided by publisher.

Unrooted : botany, motherhood, and the fight to save an old science
Growing up in rural Ontario, Erin Zimmerman became fascinated with plants - an obsession that led to a life in academia as a professional botanist. But as her career choices narrowed in the face of failing institutions and subtle, but ubiquitous, sexism, Zimmerman began to doubt herself. Unrooted: Botany, Motherhood, and the Fight to Save an Old Science is a scientist's memoir, a glimpse into the ordinary life of someone in a fascinating field. This is a memoir about plants, about looking at the world with wonder, and about what it means to be a woman in academia - an environment that pushes out mothers and those with any outside responsibilities. Zimmerman delves into her experiences as a new mom, her decision to leave her position in post-graduate research, and how she found a new way to stay in the field she loves. She also explores botany as a \"dying science\" worth fighting for. While still an undergrad, Zimmerman's university started the process of closing the Botany Department, a sign of waning funding for her beloved science. Still, she argues for its continuation, not only because we have at least 100,000 plant species yet to be discovered, but because an understanding of botany is crucial in the fight against climate change and biodiversity loss. Zimmerman is also a botanical illustrator and will provide 8 original illustrations for the book.

Twitter unearths imperiled species
Gewin offers information on Plants are Cool, Too!, a web-based video series produced by Chris Martine, a botany professor and herbarium manager at Bucknell University. Like many scientists, Martine uses Twitter to connect with other botanists and share information. Until now, his efforts had never yielded an unexpected discovery.

Deep learning-based segmentation and classification of leaf images for detection of tomato plant disease
Plants contribute significantly to the global food supply. Various Plant diseases can result in production losses, which can be avoided by maintaining vigilance. However, manually monitoring plant diseases by agriculture experts and botanists is time-consuming, challenging and error-prone. To reduce the risk of disease severity, machine vision technology (i.e., artificial intelligence) can play a significant role. In the alternative method, the severity of the disease can be diminished through computer technologies and the cooperation of humans. These methods can also eliminate the disadvantages of manual observation. In this work, we proposed a solution to detect tomato plant disease using a deep leaning-based system utilizing the plant leaves image data. We utilized an architecture for deep learning based on a recently developed convolutional neural network that is trained over 18,161 segmented and non-segmented tomato leaf images—using a supervised learning approach to detect and recognize various tomato diseases using the Inception Net model in the research work. For the detection and segmentation of disease-affected regions, two state-of-the-art semantic segmentation models, i.e., U-Net and Modified U-Net, are utilized in this work. The plant leaf pixels are binary and classified by the model as Region of Interest (ROI) and background. There is also an examination of the presentation of binary arrangement (healthy and diseased leaves), six-level classification (healthy and other ailing leaf groups), and ten-level classification (healthy and other types of ailing leaves) models. The Modified U-net segmentation model outperforms the simple U-net segmentation model by 98.66 percent, 98.5 IoU score, and 98.73 percent on the dice. InceptionNet1 achieves 99.95% accuracy for binary classification problems and 99.12% for classifying six segmented class images; InceptionNet outperformed the Modified U-net model to achieve higher accuracy. The experimental results of our proposed method for classifying plant diseases demonstrate that it outperforms the methods currently available in the literature.

The multifarious Mr. Banks : from Botany Bay to Kew, the natural historian who shaped the world
As official botanist on James Cook's first circumnavigation, the longest-serving president of the Royal Society, advisor to King George III, the \"father of Australia,\" and the man who established Kew as the world's leading botanical garden, Sir Joseph Banks was integral to the English Enlightenment. Yet he has not received the recognition that his multifarious achievements deserve. In this engaging account, Toby Musgrave reveals the true extent of Banks's contributions to science and Britain. From an early age Banks pursued his passion for natural history through study and extensive travel, most famously on the HMS Endeavour. He went on to become a pivotal figure in the advancement of British scientific, economic, and colonial interests. With his enquiring, enterprising mind and extensive network of correspondents, Banks's reputation and influence were global. Drawing widely on Banks's writings, Musgrave sheds light on Banks's profound impact on British science and empire in an age of rapid advancement.-- Source other than the Library of Congress.
