Download or read book Trees in Trouble written by Daniel Mathews and published by Catapult. This book was released on 2020-04-07 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: A troubling story of the devastating and compounding effects of climate change in the Western and Rocky Mountain states, told through in–depth reportage and conversations with ecologists, professional forest managers, park service scientists, burn boss, activists, and more. Climate change manifests in many ways across North America, but few as dramatic as the attacks on our western pine forests. In Trees in Trouble, Daniel Mathews tells the urgent story of this loss, accompanying burn crews and forest ecologists as they study the myriad risk factors and refine techniques for saving this important, limited resource. Mathews transports the reader from the exquisitely aromatic haze of ponderosa and Jeffrey pine groves to the fantastic gnarls and whorls of five–thousand–year–old bristlecone pines, from genetic test nurseries where white pine seedlings are deliberately infected with their mortal enemy to the hottest megafire sites and neighborhoods leveled by fire tornadoes or ember blizzards. Scrupulously researched, Trees in Trouble not only explores the devastating ripple effects of climate change, but also introduces us to the people devoting their lives to saving our forests. Mathews also offers hope: a new approach to managing western pine forests is underway. Trees in Trouble explores how we might succeed in sustaining our forests through the challenging transition to a new environment.

Download or read book Responses of Fruit Trees to Global Climate Change written by Fernando Ramirez and published by Springer. This book was released on 2015-01-09 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: ​Global climate change is expected to produce increased carbon dioxide levels in the atmosphere, higher temperatures, aberrant precipitation patterns and a host of other climatic changes that would affect all life on this planet. This review article addresses the impact of climate change on fruit trees and the response of the trees to a changing environment. The response of fruit trees to increasing carbon dioxide levels, phenological changes occurring in the trees themselves due to increased temperature and the lower chilling hours especially in the temperate regions, ecophysiological adaptations of the trees to the changing climate, impact of aberrant precipitation, etc. are reviewed. There is very little data on the impact of rising CO2 levels on fruit tree performance or productivity including the temperate region. Based on a large number of observations on the phenology, there is reason to believe that the flowering and fruiting of most species have advanced by quite a few days, but with variations in different crops and on different continents. The chilling hours have also grown shorter in many regions, causing considerable reductions in yield for several species. In the tropics, there is very little work on fruit trees; however, the available data show that precipitation is a major factor regulating their phenology and yield. The ecophysiological adaptations vary from species to species, and there is a need to develop phenological models in order to estimate the impact of climate change on plant development in different regions of the world. More research is also called for to develop adaptation strategies to circumvent the negative impacts of climate change.

Download or read book Witness Tree written by Lynda Mapes and published by Bloomsbury Publishing USA. This book was released on 2017-04-11 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: An intimate look at one majestic hundred-year-old oak tree through four seasons--and the reality of global climate change it reveals. In the life of this one grand oak, we can see for ourselves the results of one hundred years of rapid environmental change. It's leafing out earlier, and dropping its leaves later as the climate warms. Even the inner workings of individual leaves have changed to accommodate more CO2 in our atmosphere. Climate science can seem dense, remote, and abstract. But through the lens of this one tree, it becomes immediate and intimate. In Witness Tree, environmental reporter Lynda V. Mapes takes us through her year living with one red oak at the Harvard Forest. We learn about carbon cycles and leaf physiology, but also experience the seasons as people have for centuries, watching for each new bud, and listening for each new bird and frog call in spring. We savor the cadence of falling autumn leaves, and glory of snow and starry winter nights. Lynda takes us along as she climbs high into the oak's swaying boughs, and scientists core deep into the oak's heartwood, dig into its roots and probe the teeming life of the soil. She brings us eye-level with garter snakes and newts, and alongside the squirrels and jays devouring the oak's acorns. Season by season she reveals the secrets of trees, how they work, and sustain a vast community of lives, including our own. The oak is a living timeline and witness to climate change. While stark in its implications, Witness Tree is a beautiful and lyrical read, rich in detail, sweeps of weather, history, people, and animals. It is a story rooted in hope, beauty, wonder, and the possibility of renewal in people's connection to nature.

Download or read book Managing Landscapes for Change written by Robert M. Scheller and published by Springer Nature. This book was released on 2020-11-27 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses how future landscapes will be shaped by pervasive change and where, when, and how society should manage landscapes for change. Readers will learn about the major anthropogenic drivers of landscape change, including climate change and human induced disturbance regimes, and the unique consequences that multiple and simultaneously occurring change agents can have on landscapes. The author uses landscape trajectories as a guide to selecting the appropriate course of action, and considers how landscape position, inertia, and direction will determine landscape futures. The author introduces the concept of landscapes as socio-technical-ecological systems (STES), which combines ecological and technological influences on future landscape change and the need for society to acknowledge both when considering landscape management. Thinking beyond solutions, the author identifies barriers to managing landscapes for change including the cost, cultural identity of local populations, and the fear of taking action under uncertain conditions. Nevertheless, processes, tools, and technologies exist for overcoming social and ecological barriers to managing landscapes for change, and continued investment in social and scientific infrastructure holds out hope for maintaining our landscape values even as we enter an era of unprecedented change and disruption.

Download or read book The Journeys of Trees: A Story about Forests, People, and the Future written by Zach St. George and published by W. W. Norton & Company. This book was released on 2020-07-14 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: An urgent and illuminating portrait of forest migration, and of the people studying the forests of the past, protecting the forests of the present, and planting the forests of the future. Forests are restless. Any time a tree dies or a new one sprouts, the forest that includes it has shifted. When new trees sprout in the same direction, the whole forest begins to migrate, sometimes at astonishing rates. Today, however, an array of obstacles—humans felling trees by the billions, invasive pests transported through global trade—threaten to overwhelm these vital movements. Worst of all, the climate is changing faster than ever before, and forests are struggling to keep up. A deft blend of science reporting and travel writing, The Journeys of Trees explores the evolving movements of forests by focusing on five trees: giant sequoia, ash, black spruce, Florida torreya, and Monterey pine. Journalist Zach St. George visits these trees in forests across continents, finding sequoias losing their needles in California, fossil records showing the paths of ancient forests in Alaska, domesticated pines in New Zealand, and tender new sprouts of blight-resistant American chestnuts in New Hampshire. Everywhere he goes, St. George meets lively people on conservation’s front lines, from an ecologist studying droughts to an evolutionary evangelist with plans to save a dying species. He treks through the woods with activists, biologists, and foresters, each with their own role to play in the fight for the uncertain future of our environment. An eye-opening investigation into forest migration past and present, The Journeys of Trees examines how we can all help our trees, and our planet, survive and thrive.

Download or read book Trees in a Changing Environment written by Michael Tausz and published by Springer. This book was released on 2014-08-26 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book delivers current state-of-the-science knowledge of tree ecophysiology, with particular emphasis on adaptation to a novel future physical and chemical environment. Unlike the focus of most books on the topic, this considers air chemistry changes (O3, NOx, and N deposition) in addition to elevated CO2 effects and its secondary effects of elevated temperature. The authors have addressed two systems essential for plant life: water handling capacity from the perspective of water transport; the coupling of xylem and phloem water potential and flow; water and nutrition uptake via likely changes in mycorrhizal relationships; control of water loss via stomata and its retention via cellular regulation; and within plant carbon dynamics from the perspective of environmental limitations to growth, allocation to defences, and changes in partitioning to respiration. The authors offer expert knowledge and insight to develop likely outcomes within the context of many unknowns. We offer this comprehensive analysis of tree responses and their capacity to respond to environmental changes to provide a better insight in understanding likelihood for survival, as well as planning for the future with long-lived, stationary organisms adapted to the past: trees.
