Book Synopsis Effect of Disturbance on Natural Forest Regeneration in a Changing Tropical Environment by : Donald Mlambo
Download or read book Effect of Disturbance on Natural Forest Regeneration in a Changing Tropical Environment written by Donald Mlambo and published by Frontiers Media SA. This book was released on 2023-11-22 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent research shows that tropical forests are experiencing changes driven by many factors including deforestation and fragmentation, over-exploitation, invasive species, wildfires, insect and pathogen outbreaks, drought, windstorms and other climatically-enhanced events. Due to climate change, these disturbance events are becoming unprecedented in their frequency, extent and intensity. There is increasing concern that they may impact natural forest regeneration processes and drive rare and sensitive tropical woody plant species along an extinction trajectory. Although natural regeneration has potential to enhance ecological resilience, support local biodiversity, and provide ecosystem goods and services, it is often overlooked as an approach that can be aligned with biodiversity conservation goals, ecological restoration and climate change mitigation targets. Promoting natural forest regeneration may actually be less costly and more effective for restoring ecosystem functions.
Book Synopsis Tropical Forests in Transition by : J. Goldammer
Download or read book Tropical Forests in Transition written by J. Goldammer and published by Birkhäuser. This book was released on 2013-03-08 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: In evolutionary time scales natural disturbances have affected the vegetation on Earth. During the Quaternary the forest biomes of the tropics were subjected to manifold disturbances. Climate changes and climate oscillations were associated with changing precipitation and drought regimes, flooding, siltation, landslides, etc. The prehistorical forest was also influenced by the effects of large wildlife populations. Large-scale catastrophies in the forest biomes were mainly caused by abiotic environmental alterations, the small-scale disturbances were and still are related to both biotic and abiotic processes. Both the large-and the small-scale disturbances have played a significant role in shaping distribution, dynamics, structure and composition of the paleoforest. After the expansion of hominids and early humans, and later, by modern humans, the anthropogenic influences on the tropical forest began to overlap natural disturbances. Today's anthropogenic impacts on the tropical forests differ qualitatively and quanitatively from the natural disturbances. The speed of tropical deforestation and savannization is dramatically increasing. The physical and chemical impacts of forest conversion and biomass burning add to other anthropogenic influences on the atmosphere and climate. The expected anthropogenic climate change will also have considerable impacts on the tropical flora and fauna. The book on "Tropical Forests in Transition" synthesizes information on changing environmental conditions and human impacts on the tropical forest by looking back to the paleoecology, analyzing the impact of modern human populations and modeling the future of the tropical forest in a changing environment. The aim of the book is to strengthen multidisciplinary thinking in disturbance ecology.
Book Synopsis A Caribbean Forest Tapestry by : Nicholas Brokaw
Download or read book A Caribbean Forest Tapestry written by Nicholas Brokaw and published by Oxford University Press. This book was released on 2012-06-21 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global change threatens ecosystems worldwide, and tropical systems with their high diversity and rapid development are of special concern. We can mitigate the impacts of change if we understand how tropical ecosystems respond to disturbance. For tropical forests and streams in Puerto Rico this book describes the impacts of, and recovery from, hurricanes, landslides, floods, droughts, and human disturbances in the Luquillo Mountains of Puerto Rico. These ecosystems recover quickly after natural disturbances, having been shaped over thousands of years by such events. Human disturbance, however, has longer-lasting impacts. Chapters are by authors with many years of experience in Puerto Rico and other tropical areas and cover the history of research in these mountains, a framework for understanding disturbance and response, the environmental setting, the disturbance regime, response to disturbance, biotic mechanisms of response, management implications, and future directions. The text provides a strong perspective on tropical ecosystem dynamics over multiple scales of time and space.
Book Synopsis Changes and Disturbance in Tropical Rainforest in South-East Asia by : D. M. Newbery
Download or read book Changes and Disturbance in Tropical Rainforest in South-East Asia written by D. M. Newbery and published by World Scientific. This book was released on 2000 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Views on the dynamics of tropical forests are changing rapidly with the recognition that their environment is variable on the decadal to century scale. Fluctuating climatic conditions partly determine tropical forest structure, species composition and dynamics. Tropical communities are also highly contingent in space and time with respect to site and historical factors. Tropical forests have experienced to some degree this disturbance regime in the past, but climatologists are now predicting increasingly frequent extreme events in the new century. The combination of increasing deforestation and land-use conversion by man plus an increasingly variable environment means a situation that could be very difficult to manage.
Download or read book Second Growth written by Robin L. Chazdon and published by University of Chicago Press. This book was released on 2014-05-23 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: For decades, conservation and research initiatives in tropical forests have focused almost exclusively on old-growth forests because scientists believed that these “pristine” ecosystems housed superior levels of biodiversity. With Second Growth, Robin L. Chazdon reveals those assumptions to be largely false, bringing to the fore the previously overlooked counterpart to old-growth forest: second growth. Even as human activities result in extensive fragmentation and deforestation, tropical forests demonstrate a great capacity for natural and human-aided regeneration. Although these damaged landscapes can take centuries to regain the characteristics of old growth, Chazdon shows here that regenerating—or second-growth—forests are vital, dynamic reservoirs of biodiversity and environmental services. What is more, they always have been. With chapters on the roles these forests play in carbon and nutrient cycling, sustaining biodiversity, providing timber and non-timber products, and integrated agriculture, Second Growth not only offers a thorough and wide-ranging overview of successional and restoration pathways, but also underscores the need to conserve, and further study, regenerating tropical forests in an attempt to inspire a new age of local and global stewardship.
Book Synopsis Handbook of Research on the Conservation and Restoration of Tropical Dry Forests by : Bhadouria, Rahul
Download or read book Handbook of Research on the Conservation and Restoration of Tropical Dry Forests written by Bhadouria, Rahul and published by IGI Global. This book was released on 2019-09-27 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical dry forests are the most exploited and endangered ecosystems in the world. A combination of climatic and human factors often reduce these forests to patches of dry scrubs or savannas. Because these ecosystems experience a more arduous and less anticipated environment, they are more prone to environmental stress as plant communities are developed. Therefore, urgent research is necessary to understand both the detrimental issues and problem-solving approaches to conserving these important forests. The Handbook of Research on the Conservation and Restoration of Tropical Dry Forests is a pivotal reference source that combines theory and practice on the current trends and issues in this important ecological subject and discusses future challenges towards conservation strategies of these tropical dry forests. While highlighting topics such as forest management, natural regeneration, and silviculture, this publication examines the anthropogenic impacts on tropical dry forests and the necessity to rebuild their ecosystems. This book is ideally designed for state forest agency professionals, resource managers, non-governmental organization agents, ecologists, botanists, environmentalists, students, and researchers seeking current research on the threats to these forests.

Book Synopsis Earth, Wind, Water, Fire by : Naomi Beth Schwartz
Download or read book Earth, Wind, Water, Fire written by Naomi Beth Schwartz and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate models predict changes to the frequency and intensity of extreme events, with large effects on tropical forests likely. Predicting these impacts requires understanding how landscape configuration and land-use change influence the susceptibility of forests to disturbances such as wind, drought, and fire. This is important because most tropical forests are regenerating from anthropogenic disturbance, and are located in landscape mosaics of forest, agriculture, and other land use. This dissertation consists of four chapters that combine remote sensing and field data to examine causes and consequences of disturbance and land-use change in tropical second-growth forests. In Chapter 1, I use satellite data to identify factors associated with permanence of second-growth forest, and assess how estimates of carbon sequestration vary under different assumptions about second-growth forest permanence. I show that most second-growth forest is cleared when young, limiting carbon sequestration.
Book Synopsis Tropical Fire Ecology by : Mark Cochrane
Download or read book Tropical Fire Ecology written by Mark Cochrane and published by Springer Science & Business Media. This book was released on 2010-04-11 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tropics are home to most of the world’s biodiversity and are currently the frontier for human settlement. Tropical ecosystems are being converted to agricultural and other land uses at unprecedented rates. Land conversion and maintenance almost always rely on fire and, because of this, fire is now more prevalent in the tropics than anywhere else on Earth. Despite pervasive fire, human settlement and threatened biodiversity, there is little comprehensive information available on fire and its effects in tropical ecosystems. Tropical deforestation, especially in rainforests, has been widely documented for many years. Forests are cut down and allowed to dry before being burned to remove biomass and release nutrients to grow crops. However, fires do not always stop at the borders of cleared forests. Tremendously damaging fires are increasingly spreading into forests that were never evolutionarily prepared for wild fires. The largest fires on the planet in recent decades have occurred in tropical forests and burned millions of hectares in several countries. The numerous ecosystems of the tropics have differing levels of fire resistance, resilience or dependence. At present, there is little appreciation of the seriousness of the wild fire situation in tropical rainforests but there is even less understanding of the role that fire plays in the ecology of many fire adapted tropical ecosystems, such as savannas, grasslands and other forest types.
Book Synopsis Climate Change and Insect Pests by : Christer Bjorkman
Download or read book Climate Change and Insect Pests written by Christer Bjorkman and published by CABI. This book was released on 2015-10-01 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects, being poikilothermic, are among the organisms that are most likely to respond to changes in climate, particularly increased temperatures. Range expansions into new areas, further north and to higher elevations, are already well documented, as are physiological and phenological responses. It is anticipated that the damage by insects will increase as a consequence of climate change, i.e. increasing temperatures primarily. However, the evidence in support of this common “belief” is sparse. Climate Change and Insect Pests sums up present knowledge regarding both agricultural and forest insect pests and climate change in order to identify future research directions.
Book Synopsis Potential Impacts of Climate Change on Tropical Forest Ecosystems by : Adam Markham
Download or read book Potential Impacts of Climate Change on Tropical Forest Ecosystems written by Adam Markham and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change represents one of the most alarming long-term threats to ecosystems the world over. This new collection of papers provides, for the first time, an overview of the potentially serious impact that climate change may have on tropical forests. The authors, a multi-disciplinary group of leading experts in climatology, forestry, ecology and conservation biology, present a state-of-knowledge snapshot of how tropical forests are likely to react to the changes being wrought on our planet's atmosphere and climate. Tropical forests represent extraordinary harbours for biological diversity, and yet as deforestation and degradation continue apace, they are under greater pressure from human impacts than ever before. Climate change adds yet another threat to these valuable ecosystems, and this volume demonstrates just how significant a problem this may really be. The authors identify certain types of forest, including tropical montane cloud forest that may be particularly vulnerable. They also show the strong likelihood of global warming aggravating problems in already fragmented forest areas.
Book Synopsis Large-scale Forest Restoration by : David Lamb
Download or read book Large-scale Forest Restoration written by David Lamb and published by Routledge. This book was released on 2014-09-19 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landscapes are being degraded and simplified across the globe. This book explores how forest restoration might be carried out to increase landscape heterogeneity, improve ecological functioning and restore ecosystem services in such landscapes. It focuses on large, landscape-scale reforestation because that is the scale at which restoration is needed if many of the problems that have now developed are to be addressed. It also shows how large-scale forest restoration might improve human livelihoods as well as improve conservation outcomes. A number of governments have undertaken national reforestation programs in recent years; some have been more successful than others. The author reviews these to explore what type of reforestation should be used, where this should be carried out and how much should be done. For example, are the traditional industrial forms of reforestation necessarily the best to use in all situations? How can forest restoration be reconciled with the need for food security? And, are there spatial thresholds that must be exceeded to generate economic and environmental benefits? The book also examines the policy and institutional settings needed to encourage large-scale reforestation. This includes a discussion of the place for incentives to encourage landholders to undertake particular types of reforestation and to reforest particular locations. It also considers forms of governance that are likely to lead to an equitable sharing of the costs and benefits of forest restoration.
Book Synopsis The Ecology of Natural Disturbance and Patch Dynamics by : Steward T.A. Pickett
Download or read book The Ecology of Natural Disturbance and Patch Dynamics written by Steward T.A. Pickett and published by Elsevier. This book was released on 2013-10-22 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologists are aware of the importance of natural dynamics in ecosystems. Historically, the focus has been on the development in succession of equilibrium communities, which has generated an understanding of the composition and functioning of ecosystems. Recently, many have focused on the processes of disturbances and the evolutionary significance of such events. This shifted emphasis has inspired studies in diverse systems. The phrase "patch dynamics" (Thompson, 1978) describes their common focus. The Ecology of Natural Disturbance and Patch Dynamics brings together the findings and ideas of those studying varied systems, presenting a synthesis of diverse individual contributions.
Book Synopsis Tropical Dry Forests in the Americas by : Arturo Sanchez-Azofeifa
Download or read book Tropical Dry Forests in the Americas written by Arturo Sanchez-Azofeifa and published by CRC Press. This book was released on 2013-08-29 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under threat from natural and human disturbance, tropical dry forests are the most endangered ecosystem in the tropics, yet they rarely receive the scientific or conservation attention they deserve. In a comprehensive overview, Tropical Dry Forests in the Americas: Ecology, Conservation, and Management examines new approaches for data sampling and analysis using remote sensing technology, discusses new ecological and econometric methods, and critically evaluates the socio-economic pressures that these forest are facing at the continental and national levels. The book includes studies from Mexico, Costa Rica, Colombia, Venezuela, and Brazil that provide in-depth knowledge about the function, status, and conservation efforts of these endangered forests. It presents key elements of synthesis from standardized work conducted across all sites. This unique contribution provides new light in terms of these forests compared to each other not only from an ecological perspective but also in terms of the pressures that they are facing, and their respective responses. Written by experts from a diversity of fields, this reference brings together the many facets of function, use, heritage, and future potential of these forests. It presents an important and exciting synthesis of many years of work across countries, disciplines, and cultures. By standardizing approaches for data sampling and analysis, the book gives readers comparison information that cannot be found anywhere else given the high level of disparity that exists in the current literature.
Book Synopsis Seasonally Dry Tropical Forests by : Rodolfo Dirzo
Download or read book Seasonally Dry Tropical Forests written by Rodolfo Dirzo and published by Island Press. This book was released on 2012-09-26 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though seasonally dry tropical forests are equally as important to global biodiversity as tropical rainforests, and are one of the most representative and highly endangered ecosystems in Latin America, knowledge about them remains limited because of the relative paucity of attention paid to them by scientists and researchers and a lack of published information on the subject. Seasonally Dry Tropical Forests seeks to address this shortcoming by bringing together a range of experts in diverse fields including biology, ecology, biogeography, and biogeochemistry, to review, synthesize, and explain the current state of our collective knowledge on the ecology and conservation of seasonally dry tropical forests. The book offers a synthetic and cross-disciplinary review of recent work with an expansive scope, including sections on distribution, diversity, ecosystem function, and human impacts. Throughout, contributors emphasize conservation issues, particularly emerging threats and promising solutions, with key chapters on climate change, fragmentation, restoration, ecosystem services, and sustainable use. Seasonally dry tropical forests are extremely rich in biodiversity, and are seriously threatened. They represent scientific terrain that is poorly explored, and there is an urgent need for increased understanding of the system's basic ecology. Seasonally Dry Tropical Forests represents an important step in bringing together the most current scientific information about this vital ecosystem and disseminating it to the scientific and conservation communities.
Book Synopsis Climate Change and Agriculture Worldwide by : Emmanuel Torquebiau
Download or read book Climate Change and Agriculture Worldwide written by Emmanuel Torquebiau and published by Springer. This book was released on 2015-10-26 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, especially with the approach of the 21st Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change in Paris in late 2015, the number of publications, conferences and meetings on climate change has been growing exponentially. Yet uncertainties remain concerning rural tropical areas where models are forecasting the onset of multiple disorders and trends are unclear. Meanwhile, the impact of climate change on the poorest communities is regularly documented, often prompting alarmist reactions. How can food security be achieved while adapting to and mitigating climate change? What are the main threats to agriculture in developing countries? How do farmers in these countries cope with the threats? What does agricultural research propose? What options have yet to be investigated? A broad scope of scientific research is underway to address these challenges. Diverse solutions are available, including new agricultural practices, water management, agricultural waste recycling, diagnosis of emerging diseases, payment for ecosystem services, etc. Gaining insight into the financial and political mechanisms that underlie international climate negotiations is also essential to design practical ways to deal with climate issues and meet sustainable development requirements in collaboration with farmers. This book pools the wealth of experience of dozens of researchers and development officers from a range of disciplines. We have focused on making it detailed, accurate and hopefully easy to read for researchers, students and all other informed readers.
Book Synopsis Tropical Forests and Climate by : N. Myers
Download or read book Tropical Forests and Climate written by N. Myers and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical forests affect climate, and the removal of the forests will change climate. Or not? This book discusses basic questions on how far, if at all, tropical deforestation leads to climatic change. The question of this uncertainty is particularly addressed. One important consequence of the uncertainties of whether deforestation affects climate is how scientific findings best illuminate the policy-making process.
