Book Synopsis Plant Diversity and Ecology in the Chihuahuan Desert by : Maria C. Mandujano
Download or read book Plant Diversity and Ecology in the Chihuahuan Desert written by Maria C. Mandujano and published by Springer Nature. This book was released on 2020-07-18 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental and specific diversity in the Chihuahuan desert in general, and in the Cuatro Ciénegas Basin in particular, has long been recognized as outstanding. This book provides a global ecological overview, together with in-depth studies of specific processes. The Chihuahuan desert is the warmest in North America, and has a complex geologic, climatic and biogeographical history, which affects today’s distribution of vegetation and plants and generates complex phylogeographic patterns. The high number of endemic species reflects this complex set of traits. The modern distribution of environments, including aquatic and subaquatic systems, riparian environments, gypsum dunes and gypsum-rich soils, low levels of phosphorous and organic matter, and high salinity combined with an extreme climate call for a range of adaptations. Plants are distributed in a patchy pattern based on punctual variations, and many of them respond to different resources and conditions with considerable morphological plasticity. In terms of physiological, morphological and ecological variability, cacti were identified as the most important group in specific environments like bajadas, characterized by high diversity values, while gypsophytes and gypsovagues of different phylogenies, including species with restricted distribution and endemics.

Book Synopsis Tropical Rainforest Responses to Climatic Change by : Mark B. Bush
Download or read book Tropical Rainforest Responses to Climatic Change written by Mark B. Bush and published by Springer Science & Business Media. This book was released on 2007 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to provide a current overview of the impacts of climate change on tropical forests, to investigate past, present, and future climatic influences on the ecosystems with the highest biodiversity on the planet.Tropical Rainforest Responses to Climatic Change will be the first book to examine how tropical rain forest ecology is altered by climate change, rather than simply seeing how plant communities were altered. Shifting the emphasis onto ecological processes e.g. how diversity is structured by climate and the subsequent impact on tropical forest ecology, provides the reader with a more comprehensive coverage. A major theme of this book that emerges progressively is the interaction between humans, climate and forest ecology. While numerous books have appeared dealing with forest fragmentation and conservation, none have explicitly explored the long term occupation of tropical systems, the influence of fire and the future climatic effects of deforestation, coupled with anthropogenic emissions. Incorporating modelling of past and future systems paves the way for a discussion of conservation from a climatic perspective, rather than the usual plea to stop logging.
Book Synopsis Nesting Birds of a Tropical Frontier by : Timothy Brush
Download or read book Nesting Birds of a Tropical Frontier written by Timothy Brush and published by Texas A&M University Press. This book was released on 2005 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Halfway between Dallas and Mexico City, along the last few hundred miles of the Rio Grande, lies a subtropical outpost where people from all over the world come to see birds. Located between the temperate north and the tropic south, with desert to the west and ocean to the east, the Lower Rio Grande Valley of Texas provides habitat for a variety of birds seen nowhere else in the United States. If you want to see a Hooked-billed Kite, Muscovy Duck, or Altamira Oriole, this is the place." "Drawing on years of personal observation and study, Timothy Brush has written a classic work of natural history about the little-known breeding bird communities of the Valley and the diversity of nesting strategies and behaviors that can be seen. Brush estimates that there are more than 150 current breeding species in the Lower Rio Grande Valley. In Nesting Birds of a Tropical Frontier, he describes the habits, distribution, changes in occurrence, and general outlook of these as well as former breeders, concentrating on Valley specialties and other birds of particular interest in the Valley." "Art by Gerald Sneed and color photographs by several of Texas' top nature photographers show off some of the Valley's famous birds. Historical maps of vegetation and geology help us gain a better perspective on the changes that have taken place along the Rio Grande and on the breeding bird communities of the U.S.-Mexico frontier."--Jacket

Book Synopsis Climate and Conservation by : Jodi A. Hilty
Download or read book Climate and Conservation written by Jodi A. Hilty and published by Island Press. This book was released on 2012-05-29 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate and Conservation presents case studies from around the world of leading-edge projects focused on climate change adaptation-regional-scale endeavors where scientists, managers, and practitioners are working to protect biodiversity by protecting landscapes and seascapes in response to threats posed by climate change. The book begins with an introductory section that frames the issues and takes a systematic look at planning for climate change adaptation. The nineteen chapters that follow examine particular case studies in every part of the world, including landscapes and seascapes from equatorial, temperate, montane, polar, and marine and freshwater regions. Projects profiled range from North American grasslands to boreal forests to coral reefs to Alpine freshwater environments. Chapter authors have extensive experience in their respective regions and are actively engaged in working on climate-related issues. The result is a collection of geographical case studies that allows for effective cross-comparison while at the same time recognizing the uniqueness of each situation and locale. Climate and Conservation offers readers tangible, place-based examples of projects designed to protect large landscapes as a means of conserving biodiversity in the face of the looming threat of global climate change. It informs readers of how a diverse set of conservation actors have been responding to climate change at a scale that matches the problem, and is an essential contribution for anyone involved with large-scale biodiversity conservation.
Book Synopsis The Desert Grassland by : Mitchel P. McClaran
Download or read book The Desert Grassland written by Mitchel P. McClaran and published by University of Arizona Press. This book was released on 2023-05-23 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mixed grass and shrub vegetation known to scientists as desert grassland is common to the basins and valleys that skirt the mountain ranges throughout southwestern North America, extending from Arizona, New Mexico and Texas down through thirteen Mexican states. This variegated ground cover is crucial to life in an arid environment. The Desert Grassland offers the most comprehensive study to date of these flora and the rich biotic communities they support. Leading experts in geography, biology, botany, zoology, and geoscience present new research on the desert grassland and review a vast amount of earlier work. They reveal that present-day grasses once grew in the ice-age forests that existed in these areas before the climate dried and the trees vanished and how the intensity and frequency of fire can influence the plant and animal species of the grassland. They also document how the influence of humans—from Amerindians to contemporary ranchers, public land managers, and real estate developers—has changed the relative abundance of woody and herbaceous species and how the introduction of new plants and domesticated animals to the area has also affected biodiversity. The book concludes with a review of the attempts, both failed and successful, to reestablish plants in desert grasslands affected by overgrazing, drought, and farm abandonment. Meticulously researched and copiously illustrated, The Desert Grassland is a major contribution to ecological literature. For advanced lay readers as well as students and scholars of history, geography, and ecology, it will be a standard reference work for years to come.
Book Synopsis Fire and Climatic Change in Temperate Ecosystems of the Western Americas by : Thomas T. Veblen
Download or read book Fire and Climatic Change in Temperate Ecosystems of the Western Americas written by Thomas T. Veblen and published by Springer Science & Business Media. This book was released on 2006-05-10 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both fire and climatic variability have monumental impacts on the dynamics of temperate ecosystems. These impacts can sometimes be extreme or devastating as seen in recent El Nino/La Nina cycles and in uncontrolled fire occurrences. This volume brings together research conducted in western North and South America, areas of a great deal of collaborative work on the influence of people and climate change on fire regimes. In order to give perspective to patterns of change over time, it emphasizes the integration of paleoecological studies with studies of modern ecosystems. Data from a range of spatial scales, from individual plants to communities and ecosystems to landscape and regional levels, are included. Contributions come from fire ecology, paleoecology, biogeography, paleoclimatology, landscape and ecosystem ecology, ecological modeling, forest management, plant community ecology and plant morphology. The book gives a synthetic overview of methods, data and simulation models for evaluating fire regime processes in forests, shrublands and woodlands and assembles case studies of fire, climate and land use histories. The unique approach of this book gives researchers the benefits of a north-south comparison as well as the integration of paleoecological histories, current ecosystem dynamics and modeling of future changes.

Book Synopsis Emerging zoonoses: eco-epidemiology, involved mechanisms and public health implications by : Rubén Bueno-Marí
Download or read book Emerging zoonoses: eco-epidemiology, involved mechanisms and public health implications written by Rubén Bueno-Marí and published by Frontiers Media SA. This book was released on 2015-07-06 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zoonoses are currently considered as one of the most important threats for public health worldwide. Zoonoses can be defined as any disease or infection that is naturally transmissible from vertebrate or invertebrate animals to humans and vice-versa. Approximately 75% of recently emerging infectious diseases affecting humans are diseases of animal origin; approximately 60% of all human pathogens are zoonotic. All types of potential pathogenic agents, including viruses, parasites, bacteria and fungi, can cause these zoonotic infections. From the wide range of potential vectors of zoonoses, insects are probably those of major significance due to their abundance, high plasticity and adaptability to different kinds of pathogens, high degrees of synanthropism in several groups and difficulties to apply effective programs of population control. Although ticks, flies, cockroaches, bugs and fleas are excellent insects capable to transmit viruses, parasites and bacteria, undoubtedly mosquitoes are the most important disease vectors. Mosquito borne diseases like malaria, dengue, equine encephalitis, West Nile, Mayaro or Chikungunya are zoonoses with increasing incidence in last years in tropical and temperate countries. Vertebrates can also transmit serious zoonoses, highlighting the role of some carnivorous animals in rabies dissemination or the spread of rodent borne diseases in several rural and urban areas. Moreover, the significance of other food borne zoonoses such as taeniasis, trichinellosis or toxoplasmosis may not been underestimated. According to WHO, FAO and OIE guidelines an emerging zoonotic disease can be defined as a zoonosis that is newly recognized or newly evolved, or that has occurred previously but shows an increase of incidence or expansion in geographical, host or vector range. There are many factors that can provoke or accelerate the emergence of zoonoses, such as environmental changes, habitat modifications, variations of human and animal demography, pathogens and vectors anomalous mobilization related with human practices and globalization, deterioration of the strategies of vector control or changes in pathogen genetics. To reduce public health risks from zoonoses is absolutely necessary to acquire an integrative perspective that includes the study of the complexity of interactions among humans, animals and environment in order to be able to fight against these issues of primary interest for human health. In any case, although zoonoses represent significant public health threats, many of them still remain as neglected diseases and consequently are not prioritized by some health international organisms.
Book Synopsis Sacred Natural Sites by : Bas Verschuuren
Download or read book Sacred Natural Sites written by Bas Verschuuren and published by Routledge. This book was released on 2012-06-25 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sacred Natural Sites are the world's oldest protected places. This book focuses on a wide spread of both iconic and lesser known examples such as sacred groves of the Western Ghats (India), Sagarmatha /Chomolongma (Mt Everest, Nepal, Tibet - and China), the Golden Mountains of Altai (Russia), Holy Island of Lindisfarne (UK) and the sacred lakes of the Niger Delta (Nigeria). The book illustrates that sacred natural sites, although often under threat, exist within and outside formally recognised protected areas, heritage sites. Sacred natural sites may well be some of the last strongholds for building resilient networks of connected landscapes. They also form important nodes for maintaining a dynamic socio-cultural fabric in the face of global change. The diverse authors bridge the gap between approaches to the conservation of cultural and biological diversity by taking into account cultural and spiritual values together with the socio-economic interests of the custodian communities and other relevant stakeholders.

Book Synopsis Tropical Ecosystems: Structure, Functions and Challenges in the Face of Global Change by : Satish Chandra Garkoti
Download or read book Tropical Ecosystems: Structure, Functions and Challenges in the Face of Global Change written by Satish Chandra Garkoti and published by Springer Nature. This book was released on 2019-09-24 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book brings together research topics having a broad focus on human and climate change impacts on the terrestrial ecosystems in the tropics in general and more specifically from the most significant and vulnerable Himalayan ecosystem. A total of 16 contributions included in the book cover a diverse range of global change themes such as the impacts of changing temperature and precipitation on soil ecosystems, forest degradation, extent and impacts of invasive species, plant responses to pollution, climate change impacts on biodiversity and tree phenology, environmental changes associated with land use, importance of traditional knowledge in climate change adaptation, timberline ecosystems, and role of integrated landscape modeling for sustainable management of natural resources. The book is a collective endeavour of an international multidisciplinary group of scientists focused on improving our understanding of the impacts of global change on the structure and functioning of tropical ecosystems and addressing the challenges of their future sustainable management. We hope that the book will help researchers working in the areas of ecology and environmental science to update their knowledge. We also expect that natural resource managers and policy planners will find explanations for some of their observations and hypotheses on multiple global change factors impacting tropical ecosystems and especially Himalayan ecosystems.
Book Synopsis Fundamentals of Tree Ring Research by : James H. Speer
Download or read book Fundamentals of Tree Ring Research written by James H. Speer and published by University of Arizona Press. This book was released on 2021-11-30 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree-ring dating (dendrochronology) is a method of scientific dating based on the analysis of tree-ring growth patterns. As author James Speer notes, trees are remarkable bioindicators. Although there are other scientific means of dating climatic and environmental events, dendrochronology provides the most reliable of all paleorecords. Dendrochronology can be applied to very old trees to provide long-term records of past temperature, rainfall, fire, insect outbreaks, landslides, hurricanes, and ice storms--to name only a few events. This comprehensive text addresses all of the subjects that a reader who is new to the field will need to know and will be a welcome reference for practitioners at all levels. It includes a history of the discipline, biological and ecological background, principles of the field, basic scientific information on the structure and growth of trees, the complete range of dendrochronology methods, and a full description of each of the relevant subdisciplines. Individual chapters address the composition of wood, methods of field and laboratory study, dendroarchaeology, dendroclimatology, dendroecology, dendrogeomorphology, and dendrochemistry. The book also provides thorough introductions to common computer programs and methods of statistical analysis. In the final chapter, the author describes "frontiers in dendrochronology," with an eye toward future directions in the field. He concludes with several useful appendixes, including a listing of tree and shrub species that have been used successfully by dendrochronologists. Throughout, photographs and illustrations visually represent the state of knowledge in the field.
Download or read book Biodiversity written by N. Biedinger and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity, sometimes simply understood as "diversity of species", is a specific quality of life on our planet, the dimensions and importance of which have just lately been fully realized. Today we know that "biological diversity is a global asset of incalculable value to present and future generations" (Kofi Annan). Biodiversity is spread unequally over the world: in fact, the main share of biological resources worldwide is harboured predominantly by the so-called developing countries in the tropics and sub tropics. Therefore, Biodiversity - A Challenge for Development Research and Policy was chosen as the title for an international conference which was held in Bonn in 1997 as one of the first major events organized by the then newly established North-South Centre for Development Research (ZEF) at Rheinische Friedrich-Wilhelms-Universitat Bonn (Germany). Since the ZEF, founded by the Senate of the University of Bonn in 1995, has played a central role in turning Bonn into a centre for international cooperation and North-South dialogue. The Centre is a product of the Bonn Berlin agreement of July 1994 which was adopted to offset the effects caused by the Parliament and much of the Government moving to Berlin. It fits in well with the double strategy to strengthen Bonn's position as an interna tional science arena and as an eminent place for development policy and the national and supranational agencies dealing with this issue.
