Download or read book The Nature of Desert Nature written by Gary Paul Nabhan and published by University of Arizona Press. This book was released on 2020-11-10 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this refreshing collection, one of our best writers on desert places, Gary Paul Nabhan, challenges traditional notions of the desert. Beautiful, reflective, and at times humorous, Nabhan’s extended essay also called “The Nature of Desert Nature” reveals the complexity of what a desert is and can be. He passionately writes about what it is like to visit a desert and what living in a desert looks like when viewed through a new frame, turning age-old notions of the desert on their heads. Nabhan invites a prism of voices—friends, colleagues, and advisors from his more than four decades of study of deserts—to bring their own perspectives. Scientists, artists, desert contemplatives, poets, and writers bring the desert into view and investigate why these places compel us to walk through their sands and beneath their cacti and acacia. We observe the spines and spears, stings and songs of the desert anew. Unexpected. Surprising. Enchanting. Like the desert itself, each essay offers renewed vocabulary and thoughtful perceptions. The desert inspires wonder. Attending to history, culture, science, and spirit, The Nature of Desert Nature celebrates the bounty and the significance of desert places. Contributors Thomas M.

Download or read book Seed Germination in Desert Plants written by Yitzchak Gutterman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: During germination, the most resistant stage of the life cycle - the seed - changes to the most sensitive stage, namely the seedling. Therefore, in desert plant species seed dispersal and subsequent germination in the optimum time an place place are particularly critical parameters. Discussed here are the ways and means by which desert plants have adapted through the course of evolution to their extreme environment. Two such strategies which have evolved are a) plants with relatively large and protected seeds which germinate when the chance of seedling survival is high and the risk relatively low or b) those with an opportunistic strategy: minute seeds which germinate after low rainfall under high risk for seedling survival if additional rain does not follow. Most species adopt a combination of the two mechanisms. Species have adapted both genotypically and phenotypically, both aspects of which are also discussed in this thorough text. The reader is provided with a good understanding of the complex influences on each seed traced through from initial development to germination stage regarding germination preparation and subsequent survival.

Download or read book Ecology of Desert Systems written by Walter G. Whitford and published by Academic Press. This book was released on 2019-08-20 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly one-third of the land area on our planet is classified as arid or desert. Therefore, an understanding of the dynamics of such arid ecosystems is essential to managing those systems in a way that sustains human populations. This second edition of Ecology of Desert Systems provides a clear, extensive guide to the complex interactions involved in these areas. This book details the relationships between abiotic and biotic environments of desert ecosystems, demonstrating to readers how these interactions drive ecological processes. These include plant growth and animal reproductive success, the spatial and temporal distribution of vegetation and animals, and the influence of invasive species and anthropogenic climate change specific to arid systems. Drawing on the extensive experience of its expert authors, Ecology of Desert Systems is an essential guide to arid ecosystems for students looking for an overview of the field, researchers keen to learn how their work fits in to the overall picture, and those involved with environmental management of desert areas. Highlights the complexity of global desert systems in a clear, concise way Reviews the most current issues facing researchers in the field, including the spread of invasive species due to globalized trade, the impact of industrial mining, and climate change Updated and extended to include information on invasive species management, industrial mining impacts, and the current and future role of climate change in desert systems
Download or read book Dynamics of Native and Invasive Non native Plant Species in Desert Sand Dunes of Eureka Valley Death Valley National Park written by Elaine K. Chow and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The dynamics of native and non-native invasive plant species in desert sand dune environments have not been well explored. This is partially due to the isolation of inland dunes. For the same reason, endemism is likely to occur. Thus, invasions of desert dunes pose a large threat to endemic taxa that are confined to these terrestrial islands. One of the most floristically species-rich sand dune ecosystems of western North America is in Eureka Valley, Death Valley National Park. Park managers and conservationists fear that populations of two of the three dune endemics may be vulnerable to the invasion of Salsola gobicola. Furthermore, one of those two vulnerable species, Oenothera californica ssp. eurekensis, is currently listed as federally endangered. Despite a scarcity of reliable monitoring data, the U.S. Fish & Wildlife Service (U.S.F.W.S.) recently proposed to delist the subspecies because the original threat to the population, off-road vehicle usage, was removed. However, solid observational or experimental data on the biological threat of S. gobicola on the dune endemic and other native populations are lacking. The potential impacts of S. gobicola were explored through target-neighborhood approaches (one observational and one experimental) to examine the influences of inter- and intraspecific competitive effects as well as effects of neighbor density in the non-native species and two native species, Crypthantha micrantha and O. californica ssp. eurekensis. The observational field study suggested competition between two abundant populations of annuals, S. gobicola and C. micrantha. Comparisons of natural density gradients of neighbors of S. gobicola, C. micrantha, all species excluding conspecifics, and all species including both study species of interest indicated the latter two variables had the most influence on performance of S. gobicola and C. micrantha targets, respectively. This implies diffuse competition may play a stronger role than inter- and intraspecific competition among the native and non-native annual species observed. A manipulative pot study was conducted with S. gobicola and the perennial, O. californica ssp. eurekensis to directly determine the effects of inter- and intraspecific neighbors, neighbor density and stage class (first- and second-year) of perennial plants on target plant performance of both species. The manipulative study revealed the strongest competitors were the older perennial targets and neighbors in both intra- and interspecific competition. The response to neighbor density on the native species differed between studies; negative and positive effects were observed in the field study and no effect was observed in the manipulative study. However, both studies indicated that S. gobicola was, at best, competitively similar to the competitive effects of the native species. These outcomes on the competitive effects of the invasive species on a common desert annual and a rare endemic species may dispel the bias that invasive species are stronger competitors than rare and native species. To address the scarcity of reliable population data on O. californica ssp. eurekensis for both park managers and the U.S.F.W.S., a monitoring study was implemented in the field. The method of distance-sampling was used for its repeatability, efficiency, accuracy and precision in estimating abundance of rare species. The four-year data set revealed large variability in the spatio-temporal distribution and abundance of the endangered species at multiple scales. Thus, more years of monitoring appears necessary to determine population trends and stability. Nevertheless, these more reliable population estimates and the findings from the competition studies can better inform management strategies of both invasive and sensitive native species. Furthermore, such observational and manipulative studies can improve our understanding of invasions in unique and protected ecosystems like the sand dunes in Eureka Valley.

Download or read book Flora of the Gran Desierto and R o Colorado Delta written by Richard Stephen Felger and published by University of Arizona Press. This book was released on 2023-02-07 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Pinacate lava fields and expansive dunes to the shores of the Gulf of California, the Gran Desierto is one of the hottest and driest places in the Western Hemisphere. Yet this region in the state of Sonora in northwestern Mexico embraces a remarkable number of habitats with a fascinating and surprisingly rich flora. This is the heart of the Sonoran Desert, still in a largely primordial state, in juxtaposition with the ravished wetlands of the once great Río Colorado. Flora of the Gran Desierto is the culmination of more than twenty-five years of research in this magnificent desert and delta by botanist Richard Felger. This comprehensive floristic study of more than 565 species of vascular plants features original diagnostic descriptions and innovative identification keys to the families, genera, and species. Particular attention has been devoted to taxa that are poorly known. Even weeds and their histories are treated in detail. Hundreds of illustrations by such eminent botanical artists as Lucretia Brezeale Hamilton, Matt Johnson, and Bobbi Angell will aid in the identification of plants. Common names of plants are given in English, Spanish, and O'odham. While emphasizing scientific accuracy, the book is written in an accessible style. Felger's observations and knowledge of plant ecology, geographic distribution, evolution, ethnobotany, plant variation and special adaptations, and the history of the region provides botanists, naturalists, ecologists, conservationists, and anyone else celebrating the desert with readable, interesting, and important information. With two of Mexico's newest biosphere reserves—the Pinacate and the Upper Gulf of California—this region is a keystone for desert conservation efforts. Its location linking vast preserves to the north makes this book especially useful for anyone interested in borderland studies and the Sonoran Desert. Flora of the Gran Desierto represents a most creative, definitive, and enthusiastic treatment of Sonoran Desert plant life and is highly relevant to ecological restoration in deserts and wetlands in arid places worldwide.
