Available in PDF, EPUB and Kindle. Book excerpt: While Barton Springs Pool is an iconic landmark of Austin and many people are familiar with the end of Barton Creek and its seven miles of public greenbelt, less is known about the forty-odd miles beyond that tumble and twist across private lands, eventually feeding the Colorado River. Legendary fights saved Barton Springs in the 1980s and 1990s, when the pool repeatedly was closed because of pollutant runoff from streets, nearby construction, and leaking sewer lines. In 1992, a highly publicized campaign resulted in land protections and stricter water standards. But will the creek and its springs become fouled again? That possibility arises upstream where tributaries and other creeks flow across mostly rural acreage, attracting new housing and business developments. Not only would city bathers lose access to the pool, but endangered species of salamanders and birds that depend on the Edwards Aquifer and its unique habitats face an uncertain future. Following the creek from downtown Austin’s Barton Springs Pool to its source as a cow-pasture trickle, longtime resident and journalist Ed Crowell explores the creek’s contentious political history, its historic and current residents, and the mounting environmental pressures threatening it. Barton Creek highlights the passionate individuals involved in the stream’s preservation, from city scientists to local landowners, who want to see the creek running clear and clean for future generations. Striking photography and vivid descriptions will entice readers to fall in love with Barton Creek all over again.

Download or read book Unnatural Texas? written by Robin W. Doughty and published by Texas A&M University Press. This book was released on 2019-02-14 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: The story of introduced species in Texas is long (hogs were introduced by European settlers in the 1500s) and fraught with controversy. In Unnatural Texas? The Invasive Species Dilemma, Robin W. Doughty and Matt Warnock Turner introduce the “big hitters” of invasive species in the state. They profile the usual suspects—feral hogs, salt cedar, and fire ants—and also lesser known invasives, such as cats and sparrows. Blending natural and environmental history with geography, this book is a much-needed, balanced exploration of invasive species in Texas. The distinctions between native and invasive are not hard and fast, and perceptions of what is invasive have changed over the centuries. A striking example, free-ranging cats—domestic, stray, and feral—can wreak havoc on small mammal and bird populations. There is not a one-size-fits-all solution for invasives, and removal or complete eradication may not be possible or even desirable. The dilemma of what to do about invasive species also raises moral, social, economic, and cultural questions. This engaging introduction to the concept of invasive species in Texas will provide context for readers and will educate people on this important issue facing the state.

Download or read book The Writings of Ferdinand Lindheimer written by John E. Williams and published by Texas A&M University Press. This book was released on 2020-09-25 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ferdinand Jacob Lindheimer is known as the “father of Texas botany.” While he was not the first botanist to collect plants for scientific examination in Texas, his collections are credited with helping botanists around the world to understand the nature, extent, and significance of the diversity of plants in the state. In partnership with Asa Gray of Harvard University, Lindheimer spent eight years collecting Texas plants to distribute to a list of paying subscribers—including places like the British Museum, the Royal Botanic Gardens at Kew, and the Smithsonian Institution. Today, no fewer than 362 plant names are based, at least in part, on Lindheimer collections, and 65 plants have been named in his honor. Lindheimer was a founding settler of New Braunfels, raising his family on the banks of the Comal River while he continued to collect and ship plant specimens. He was “elected” as the first editor of the Neu-Braunfelser Zeitung (still published today as the Herald-Zeitung), and served from 1852 to 1872. He wrote a number of articles for the Zeitung on topics ranging from plants, climate, and agriculture to Texas Indian affairs, optimism, and teaching schoolchildren. In the last year of Lindheimer’s life, one of his students worked with him to collect an assortment of his essays and articles from the Zeitung. In 1879, the collection was published as Aufsätze und Abhandlungen von Ferdinand Lindheimer in Texas (Essays and Articles of Ferdinand Lindheimer in Texas). John E. Williams now offers the first English translation of these essays, which provides valuable insight into the natural and cultural history of Texas.

Download or read book Ecology of North America written by Eric G. Bolen and published by John Wiley & Sons. This book was released on 1998-02-18 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: From windswept tundra to humid subtropical everglades, fromgracious coniferous forests to austere deserts, North America isblessed with an incredibly diverse array of natural environments,each supporting a unique system of plant and animal life. Thesesystems--also known as biomes--are tightly woven webs of life thathave taken millennia to evolve. This lavishly illustrated bookintroduces readers to this extraordinary array of naturalcommunities and to the subtle interactions of minerals, plants, andanimals that take place within them. Professor Eric Bolen takes a qualitative, intuitive approach to hissubject, beginning with an overview of essential ecological termsand concepts, such as competitive exclusion, taxa, niches, andsuccession. Then, biome by biome, he covers the entirety of Canadaand the United States, starting with the tundra of the far northand working his way south and then west to conclude in the desertsand chaparral of southern California. Along the way, he delves intopertinent conservation issues and features fascinating historicalvignettes and original documents detailing human impact on variousenvironments--for instance, the role of John Deere's plow insettling grasslands, and the use of fur records from Hudson's BayCompany. Throughout, he enlivens the text with dozens of exquisitephotographs and illuminating maps, graphs, charts, andtables. Ecology of North America is an ideal first text for studentsinterested in natural resources, environmental science, andbiology, and it is a useful and attractive addition to the libraryof anyone interested in understanding and protecting the naturalenvironment.

Book excerpt: A treasury like no other Since the 1500s, scientists have documented the plants and fungi that grew around them, organizing the specimens into collections. Known as herbaria, these archives helped give rise to botany as its own scientific endeavor. Herbarium is a fascinating enquiry into this unique field of plant biology, exploring how herbaria emerged and have changed over time, who promoted and contributed to them, and why they remain such an important source of data for their new role: understanding how the world’s flora is changing. Barbara Thiers, director of the William and Lynda Steere Herbarium at the New York Botanical Garden, also explains how recent innovations that allow us to see things at both the molecular level and on a global scale can be applied to herbaria specimens, helping us address some of the most critical problems facing the world today. At its heart, Herbarium is a compelling reminder of one of humanity’s better impulses: to save things—not just for ourselves, but for generations to come.

Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to anyone who is in search of beauty in mathematics, and mathematics in the beauty around us. Attempting to combine mathematical rigor and magnificence of the visual perception, the author is presenting the mathematical study of phyllotaxis, the most beautiful phenomenon of the living nature. The distinctive feature of this book is an animation feature that explains the work of mathematical models and the transformation of 3D space. The analysis of the phyllotactic pattern as a system of discrete objects together with the mathematical tools of generalized sequences made it possible to find a universal algorithm for calculating the divergence angle. In addition, it is serving as a new proof of the fundamental theorem of phyllotaxis and analytically confirming well-known formulas obtained intuitively earlier as well as casting some doubts on a few stereotypes existing in mathematical phyllotaxis. The presentation of phyllotaxis morphogenesis as a recursive process allowed the author to formulate the hydraulic model of phyllotaxis morphogenesis and propose a method for its experimental verification. With the help of artificial intelligence, the author offered methodology for the digital measurement of phyllotaxis allowing a transition to a qualitatively new level in the study of plant morphogenesis. Due to the successful combination of mathematical constructions and their visual presentation, the materials of this study are comprehensible to readers with high school advanced mathematical levels.

This book was released on 2021-02-18 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: In more than four decades as president of The Land Institute, Wes Jackson became widely known as one of the founders of the sustainable agriculture movement for his work on perennial grains and Natural Systems Agriculture. But Jackson’s contribution to contemporary intellectual and political life goes well beyond plant breeding. Ever since he created one of the first university environmental studies programs in the early 1970s, Jackson has been exploring the human predicaments around sustainability and justice, asking questions that pull not only on agriculture and ecology but also on politics, economics, and culture. That work has appeared in four sole-authored books by Jackson, but nowhere is there an accessible summary of his key ideas. Robert Jensen provides a short, elegant introduction to Jackson’s ideas on ways to provide humanity with a truly sustainable foundation in grain agriculture, presented in a way that connects to the growing concern about climate change and other ecological crises. Jackson’s strength has been in generating new ideas and pushing the envelope not only on sustainable agriculture but also on the other dramatic changes necessary if we are to create a sustainable and just society. This volume helps the reader to organize those exciting ideas in a way that can expand the horizons of students and lay readers as well as challenge specialists in these fields. In a time when critical thinking and clear understanding are desperately needed if we are to face the multiple, cascading ecological and social crises, The Restless and Relentless Mind of Wes Jackson presents Jackson’s crucial insights about the natural world and human societies that can help provide a framework for understanding the tough decisions we will have to make. But just as important is the book’s glimpse into the curiosity that drives Jackson and the creativity that distinguishes his intellectual and activist work.

Available in PDF, EPUB and Kindle. Book excerpt: Stunned by widespread ignorance about the Gulf of Mexico following the 2010 Macondo oil spill, underwater photographer Jesse Cancelmo decided to turn his camera on the marine life of this 600,000 square mile international sea that connects five US states, six Mexican states, and the island nation of Cuba. With the goal of countering dismissive descriptions of a Gulf plagued with dead zones and overrun by oil rigs, Cancelmo set out to capture a world rarely acknowledged, let alone seen. Between the Gulf's rich shoreline habitats and its prolific oceanic communities, thriving amid dazzling coral reefs, brine seeps, canyons, salt domes, and hard bottom banks, are more than 15,000 species, including an iconic cast of sea animals: sperm whales, manta rays, whale sharks, manatees, spotted dolphins, and more. Capturing images from locations all around the Gulf, Cancelmo reveals the beauty and glory of these diverse habitats and species. Although this is a book of sensational underwater photography, Cancelmo intends it to be more than a celebration of oceanic beauty. He also hopes to inspire better understanding and appreciation of the natural marine habitats in the Gulf and to strengthen support for their protection and sustainment.

Book excerpt: Developments in Plant Genetics and Breeding, 1A: Isozymes in Plant Genetics and Breeding, Part A focuses on the advancements in the processes, methodologies, and approaches involved in the study of isozymes, including its role in plant genetics and breeding. The selection first elaborates on the historical perspectives of plant isozymes, plant genetics, and isozyme systems to study gene regulation during development. Discussions focus on the use of isozyme and similar comparisons to study differential gene regulation, gene preservation, dissemination of cultivars, propagation of cultivars and breeding lines, and studies on the effect of viral infection and hormones on isozyme expression. The text then examines allozymes in gene dosage studies, gene mapping, and plastid isozymes. The manuscript takes a look at the genetics of mitochondrial isozymes, evolution of plant isozymes, and detection of somatic variation. Topics include evolution of isozymes in plants, generation of isozymes, glutamate dehydrogenase, glutamate-oxaloacetate transaminase, and malate dehydrogenase. The text also ponders on enzyme activity staining, isozymic variation and plant breeders' rights, genetic purity of commercial seed lots, and use of isozymes in plant disease research. The selection is a valuable reference for researchers interested in the role of isozymes in plant genetics and breeding.

Download or read book Flora of the Pacific Northwest written by C. Leo Hitchcock and published by University of Washington Press. This book was released on 2018-09-17 with total page 928 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flora of the Pacific Northwest, first published in 1973, became an instant classic for its innovative style of providing species descriptions in the identification keys, and for its comprehensive illustrations of nearly all treated taxa (species, subspecies, and varieties). Students rely on it as an essential primer, while veteran botanists and natural resource managers use it as the definitive reference for the region�s flora. This completely revised and updated edition captures the advances in vascular plant systematics over the decades since publication of the first edition. These advances, together with significant changes in plant nomenclature, the description of taxa new to science from the region, and the recent documentation of new native and nonnative species in the Pacific Northwest required a thorough revision of this authoritative work. Flora of the Pacific Northwest covers all of Washington, the northern half of Oregon, Idaho north of the Snake River Plain, the mountainous portion of western Montana, and the southern portion of British Columbia. It accounts for the wild-growing native and introduced vascular plants falling within those boundaries and includes: Treatment of 5,545 taxa (more than 1,000 taxa added from the first edition) Illustrations for 4,716 taxa (1,382 more than the first edition) Nomenclature changes for more than 40 percent of the taxa included in the first edition These enhancements make this new edition the most comprehensive reference on Pacific Northwest vascular plants for professional and amateur botanists, ecologists, rare plant biologists, plant taxonomy instructors, land managers, nursery professionals, and gardeners.
