Book Synopsis Ecology of an African Rain Forest by : Thomas T. Struhsaker
Download or read book Ecology of an African Rain Forest written by Thomas T. Struhsaker and published by . This book was released on 1999-02-01 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A unique book that is likely to become a benchmark for those who wish to save the rain forests through sustainable logging practices. Its uniqueness lies in the author's collection of long-term data (up to 25 years) on both plants and animals in the same site, the Kibale forest in Uganda. . . . Very highly recommended for libraries specializing in ecology, environmental science, forestry, and rain forests."--Choice "A much-needed volume that will be of interest to a wide audience, written by a leader in the field, and one with an international reputation. The current rosy advocacy for 'sustainable development' needs a wake-up call, and this is it. This volume combines some of the hottest topics in conservation science today into a cohesive whole that looks clear-eyed into the face of modern conservation in the tropics and finds it frighteningly lacking in scientific underpinning, rational consideration, and effective implementation."--Truman Young, University of California at Davis Thomas Struhsaker summarizes 20 years of research in the Kibale forest in Uganda, one of the most important centers for the study of tropical rain forests in Africa. Among the longest ongoing projects in rain forest ecology anywhere, Struhsaker's differs from the great majority of logging studies by emphasizing the fauna rather than looking only at the commercially valuable timber species. By providing long-term data on a variety of plants and animals, it offers the first truly in-depth synthesis of the consequences of selective logging in the tropics. The main body of the book demonstrates the adverse effects of logging--as many as 25 years after the event--on community structure and numerous other aspects of forest ecology. Although much has been claimed for the possibilities of sustainable logging in tropical rain forests, few data support these claims. Struhsaker demonstrates that future logging must be done at far lower intensities than is currently practiced if intact ecosystems are to be maintained. He also offers detailed recommendations for harvest plans compatible with the conservation of biodiversity and ecological integrity. The long-term data summarized here on the population dynamics of rain forest trees, primates, rodents, duikers, and elephants are unrivaled and will be widely cited, as will the data on seasonality, tree phrenology, gap dynamics, rainfall, and temperature. Struhsaker addresses the underlying causes of tropical deforestation and concludes that although there are numerous proximate factors, the ultimate causes are rapidly increasing human populations and rates of consumption per capita. He draws comparisons with relevant studies elsewhere in the tropics and offers specific recommendations to address the problems. Thomas T. Struhsaker has conducted field research in Africa over a period of 34 years. From 1970 through 1987 he established, developed, and directed the field research station in Kibale, Uganda. He maintains an active role in Kibale today and is a research scientist in the Department of Biological Anthropology and Anatomy at Duke University. His publications include The Red Colobus Monkey (1975) and more than 80 scientific and popular articles and technical reports on ecology, conservation, and animal behavior.

Book Synopsis Sustainable management of logged tropical forests in the Caribbean to ensure long-term productivity by : Gräfe, S., Köhl, M., Eckelmann, C.M., Bremner, Q., Oatham, M., Pacheco, R., Playfair, M., Shono, K.
Download or read book Sustainable management of logged tropical forests in the Caribbean to ensure long-term productivity written by Gräfe, S., Köhl, M., Eckelmann, C.M., Bremner, Q., Oatham, M., Pacheco, R., Playfair, M., Shono, K. and published by Food & Agriculture Org.. This book was released on 2021-09-01 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: To facilitate sustainable management of logged forests in the Caribbean, forest authorities of Belize, Guyana, Suriname, and Trinidad and Tobago, jointly with the Food and Agriculture Organization of the United Nations and the University of Hamburg as a scientific partner, implemented the regional project “Ensuring Long-Term Productivity of Lowland Tropical Forests in the Caribbean” financed by the German Federal Ministry of Food and Agriculture. The main objective of the project was to support the sustainable management of logged forests to maintain productivity and prevent further degradation. For this purpose, extensive field studies were conducted in the project countries, which resulted in silvicultural recommendations presented in this publication. The project findings revealed that the application of general sustainable forest management protocols for tropical production forests that set limits on harvesting does not necessarily ensure sustained productivity if the composition and management of the residual stand are not considered. The ratio of the number of harvested trees to the remaining future crop trees can provide a simple indicator of the sustainability of harvest. If the current harvest exceeds the number of future crop trees, the harvest is not sustainable. As a rule of thumb, at least one, preferably two future crop trees per harvested tree should be retained for future use. Protection of future crop trees can be a simple and practical approach to prevent high grading and degradation of the forest growing stock. The importance of reduced impact logging to reduce unnecessary damage to the future crop trees and for sustainable forest management, in general, is stressed.
Book Synopsis Ecological Strategies and Disturbance Response of Tropical Forest Trees by : Oyomoare Lolade Osazuwa-Peters
Download or read book Ecological Strategies and Disturbance Response of Tropical Forest Trees written by Oyomoare Lolade Osazuwa-Peters and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical forests store [approximately] 40% of terrestrial carbon, process six times as much carbon as is released through fossil fuel use, and are epicenters of biodiversity. Despite all that we know about tropical forests, there remains much to discover about variation in ecological strategies, differences in the way species acquire limited resources through dissimilarities in construction and allocation patterns. We also know little as to how this variation shapes the resilience of tropical tree communities to disturbance. These forests are increasingly threatened by global change stressors, such as anthropogenic land-use and climate change. Recent advances in ecological literature show that more insight into differences in ecological strategies among tropical forest species can be gained by going beyond species distributions to also examine functional trait variation. Functional traits are morphological and physiological traits that reflect allocation strategies thought to be important determinants of fitness. In the first two chapters of my dissertation, I quantified wood density and anatomical variation at multiple scales, and related this variation to ecological strategies of tropical forest tree species. The last two chapters examined effects of historical disturbance on the composition and temporal dynamics of tropical forest communities. In addition to wood density, other traits studied in these later chapters were maximum height and diameter. Across my dissertation, the scales spanned ranged from intra-individual, intra-specific, interspecific, community and temporal levels, across two tropical forests, the 50 ha CTFS plot in BCI, Panama, and the 5.2 ha long-term forest plots in Kibale National Park, Uganda. With the functional trait approach, my dissertation demonstrated several novel patterns, including 1) linear radial increases in wood density are typical of fast-growth high mortality tropical tree species, while slow-growth low mortality species show a range of radial changes in wood density including non-linear trends 2) greater variation in ecological strategies when wood density is decomposed into anatomical components, with functional consequences for species growth and mortality of saplings but not adult trees, 3) persistence of the effects of selective logging on the taxonomic and structural composition but not functional composition of a tropical forest 45 years after, and 4) inadequacy of classical successional models that assume recovery to pre-disturbance conditions for predicting the effects of selective logging on tropical forest dynamics.
Book Synopsis Bats in the Anthropocene: Conservation of Bats in a Changing World by : Christian C. Voigt
Download or read book Bats in the Anthropocene: Conservation of Bats in a Changing World written by Christian C. Voigt and published by Springer. This book was released on 2015-12-07 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on central themes related to the conservation of bats. It details their response to land-use change and management practices, intensified urbanization and roost disturbance and loss. Increasing interactions between humans and bats as a result of hunting, disease relationships, occupation of human dwellings, and conflict over fruit crops are explored in depth. Finally, contributors highlight the roles that taxonomy, conservation networks and conservation psychology have to play in conserving this imperilled but vital taxon. With over 1300 species, bats are the second largest order of mammals, yet as the Anthropocene dawns, bat populations around the world are in decline. Greater understanding of the anthropogenic drivers of this decline and exploration of possible mitigation measures are urgently needed if we are to retain global bat diversity in the coming decades. This book brings together teams of international experts to provide a global review of current understanding and recommend directions for future research and mitigation.

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 The context of REDD+ in Guyana by : Benn, V.
Download or read book The context of REDD+ in Guyana written by Benn, V. and published by CIFOR. This book was released on 2020-05-28 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Guyana is a small country with 87.5% of its area covered with forest (GFC 2018b) and lies in the center of the Guiana Shield, one of the four largest remaining standing tropical rainforests in the world. In 2006, Guyana took advantage of the recognition of the value of standing forest to mitigate climate change and became actively engaged in REDD+. Subsequently, in 2009, a Memorandum of Understanding was signed with Norway to support implementation of a Low Carbon Development Strategy (LCDS). This was a national plan to reorient Guyana’s economy and move towards more sustainable extractive industries and forest management. The bilateral agreement with Norway established a framework for performance-related finance of up to USD 250 million from 2010 to 2015 for implementation of the LCDS. Three main pillars of the LCDS, linked to its REDD+ agenda, included maintaining historically low deforestation, endorsing low carbon development and adapting to climate change (Bellfield et al. 2015).More recently, and building on the LCDS, a new Green State Development Strategy: Vision 2040 has been developed for Guyana as a “twenty-year, national development policy that reflects the guiding vision and principles of the ‘green agenda’. The central objective is development that provides a better quality of life for all Guyanese derived from the country’s natural wealth – its diversity of people and abundant natural resources (land, water, forests, mineral and aggregates, biodiversity)” (GoG 2019b, p. 1).Since 2009, CIFOR has conducted the Global Comparative Study (GCS) in 13 countries, with Guyana as the final addition. Among the GCS-REDD+ case studies, Guyana is one of the most advanced REDD+ countries, alongside Brazil (KorhonenKurki et al. 2019), and the Norway–Guyana bilateral agreement is the world’s second largest national-level REDD+ scheme (Bade 2013). Yet, Guyana’s economy still largely depends on extractive resources, with mining remaining the main driver of deforestation and forest degradation. The potential revenue anticipated from offshore oil extraction might change the country’s landscape and outlook, putting the permanence of REDD+ under scrutiny. The Guyana case study, therefore, presents many lessons on how to balance development paths without jeopardizing national forest resources.
