Biological Sciences: Ebooks

Includes our current knowledge of the invasion or encroachment and cause of population growth and spread of some dry land, arid zone woody legumes. Community structure, population growth, and competition of these woody legumes will also be examined. These species and ecosystems are both extensive and dynamic. They occur worldwide, but mainly in the arid zones of the tropics and sub-tropics. The cause of the growth and spread of these species and communities has long been claimed to be caused by distal factors rather than proximal ones. However, these species appear to be influenced and perhaps controlled by anthropogenic factors, specifically grazing and fire or lack of fire. Their overall worldwide distribution has probably changed little in the recent past, but their populations have expanded into grasslands and their density has increased in many places. Some associated communities have shown dramatic changes in response to recent large-scale droughts and the loss of most of the dominant overstory species. However, changes in the woody legume communities and their species are generally unknown. ​

WILLA Literary Award Winner in Creative Nonfiction 2022 Spur Award Winner 2022 Top Pick in Southwest Books of the Year  Honorable Mention in the At-Large NFPW Communications Contest The Forgotten Botanist is the account of an extraordinary woman who, in 1870, was driven by ill health to leave the East Coast for a new life in the West--alone. At thirty-three, Sara Plummer relocated to Santa Barbara, where she taught herself botany and established the town's first library. Ten years later she married botanist John Gill Lemmon, and together the two discovered hundreds of new plant species, many of them illustrated by Sara, an accomplished artist. Although she became an acknowledged botanical expert and lecturer, Sara's considerable contributions to scientific knowledge were credited merely as "J.G. Lemmon & wife." The Forgotten Botanist chronicles Sara's remarkable life, in which she and JG found new plant species in Arizona, California, Oregon, and Mexico and traveled throughout the Southwest with such friends as John Muir and Clara Barton. Sara also found time to work as a journalist and as an activist in women's suffrage and forest conservation. The Forgotten Botanist is a timeless tale about a woman who discovered who she was by leaving everything behind. Her inspiring story is one of resilience, determination, and courage--and is as relevant to our nation today as it was in her own time.
