Book Synopsis Seedling Recruitment in a Tropical Rain Forest by : C. E. Timothy Paine
Download or read book Seedling Recruitment in a Tropical Rain Forest written by C. E. Timothy Paine and published by VDM Publishing. This book was released on 2007 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical rain forests contain most of the world's known biological diversity. Understanding how this diversity persists in the face of anthropogenic disturbance is an increasingly critical issue. To manage and preserve intact ecosystems, and to restore degraded ones, a better knowledge of the basic ecological processes that affect them is necessary. We must be able to answer such questions as: How are plant communities structured? How is diversity maintained in species-rich ecosystems? What ecological factors determine which plants grow where? Many processes are known to shape plant communities, but what is their relative importance? Approaching answers to these questions is the primary focus of this book. The book presents a case study, built upon experiments performed in a Peruvian rain forest. The author conducted a series of manipulative experiments on tree seedlings to dissect the various forces that shape their coexistence. This book is directed to an audience of ecologists, forest researchers, and conservationists.

Book Synopsis Tropical Forest Community Ecology by : Walter Carson
Download or read book Tropical Forest Community Ecology written by Walter Carson and published by John Wiley & Sons. This book was released on 2011-08-31 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, tropical ecology has been a science often content with descriptive and demographic approaches, which is understandable given the difficulty of studying these ecosystems and the need for basic demographic information. Nonetheless, over the last several years, tropical ecologists have begun to test more sophisticated ecological theory and are now beginning to address a broad array of questions that are of particular importance to tropical systems, and ecology in general. Why are there are so many species in tropical forests and what mechanisms are responsible for the maintenance of that vast species diversity? What factors control species coexistence? Are there common patterns of species abundance and distribution across broad geographic scales? What is the role of trophic interactions in these complex ecosystems? How can these fragile ecosystems be conserved? Containing contributions from some of the world’s leading tropical ecologists, Tropical Forest Community Ecology provides a summary of the key issues in the discipline of tropical ecology: Includes contributions from some of the world’s leading tropical ecologists Covers patterns of species distribution, the maintenance of species diversity, the community ecology of tropical animals, forest regeneration and conservation of tropical ecosystems
Book Synopsis Tropical Forests by : Padmini Sudarshana
Download or read book Tropical Forests written by Padmini Sudarshana and published by IntechOpen. This book was released on 2012-03-14 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: The astounding richness and biodiversity of tropical forests is rapidly dwindling. This has severely altered the vital biogeochemical cycles of carbon, phosphorus, nitrogen etc. and has led to the change in global climate and pristine natural ecosystems. In this elegant book, we have defined "Tropical Forests" broadly, into five different themes: (1) tropical forest structure, synergy, synthesis, (2) tropical forest fragmentation, (3) impact of anthropogenic pressure, (4) Geographic Information System and remote sensing, and (5) tropical forest protection and process. The cutting-edge synthesis, detailed current reviews, several original data-rich case studies, recent experiments/experiences from leading scientists across the world are presented as unique chapters. Though, the chapters differ noticeably in the geographic focus, diverse ecosystems, time and approach, they share these five important themes and help in understanding, educating, and creating awareness on the role of "Tropical Forests" for the very survival of mankind, climate change, and the diversity of biota across the globe. This book will be of great use to the students, scientists, ecologists, population and conservation biologists, and forest managers across the globe.

Book Synopsis Tropical Rain Forest Ecology, Diversity, and Conservation by : Jaboury Ghazoul
Download or read book Tropical Rain Forest Ecology, Diversity, and Conservation written by Jaboury Ghazoul and published by Oxford University Press. This book was released on 2023-04-10 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rain forests represent the world's richest repository of terrestrial biodiversity, and play a major role in regulating the global climate. They support the livelihoods of a substantial proportion of the world's population and are the source of many internationally traded commodities. They remain (despite decades of conservation attention) increasingly vulnerable to degradation and clearance, with profound though often uncertain future costs to global society. Understanding the ecology of these diverse biomes, and peoples' dependencies on them, is fundamental to their future management and conservation. Tropical Rain Forest Ecology, Diversity, and Conservation introduces and explores what rain forests are, how they arose, what they contain, how they function, and how humans use and impact them. The book starts by introducing the variety of rain forest plants, fungi, microorganisms, and animals, emphasising the spectacular diversity that is the motivation for their conservation. The central chapters describe the origins of rain forest communities, the variety of rain forest formations, and their ecology and dynamics. The challenge of explaining the species richness of rain forest communities lies at the heart of ecological theory, and forms a common theme throughout. The book's final section considers historical and current interactions of humans and rain forests. It explores biodiversity conservation as well as livelihood security for the many communities that are dependent on rain forests - inextricable issues that represent urgent priorities for scientists, conservationists, and policy makers.
Book Synopsis Ecology of Mediterranean Evergreen Oak Forests by : Ferran Roda
Download or read book Ecology of Mediterranean Evergreen Oak Forests written by Ferran Roda and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Used by humans since ancient times, evergreen oak forests still cover extensive mountain areas of the Mediterranean Basin. These broadleaved evergreen forests occupy a transitional zone between the cool-temperate deciduous forest biome and the drier Mediterranean pine forests and shrublands. Slow growing and casting a deep shade, the sclerophyllous holm oak (Quercus ilex) absolutely dominates the closed canopy of many Mediterranean evergreen oak forests. This is a synthesis of 20 years of research on the structure, function, and dynamics of holm oak forests in two intensively studied experimental areas in Spain. By combining observational measurements at the leaf, tree, plot, and catchment scales with field experiments and modelling, the authors explore how these forests cope with strong water limitation and repeated disturbances.
Book Synopsis New Models for Ecosystem Dynamics and Restoration by : Richard J. Hobbs
Download or read book New Models for Ecosystem Dynamics and Restoration written by Richard J. Hobbs and published by Island Press. This book was released on 2013-03-19 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: As scientific understanding about ecological processes has grown, the idea that ecosystem dynamics are complex, nonlinear, and often unpredictable has gained prominence. Of particular importance is the idea that rather than following an inevitable progression toward an ultimate endpoint, some ecosystems may occur in a number of states depending on past and present ecological conditions. The emerging idea of “restoration thresholds” also enables scientists to recognize when ecological systems are likely to recover on their own and when active restoration efforts are needed. Conceptual models based on alternative stable states and restoration thresholds can help inform restoration efforts. New Models for Ecosystem Dynamics and Restoration brings together leading experts from around the world to explore how conceptual models of ecosystem dynamics can be applied to the recovery of degraded systems and how recent advances in our understanding of ecosystem and landscape dynamics can be translated into conceptual and practical frameworks for restoration. In the first part of the book, background chapters present and discuss the basic concepts and models and explore the implications of new scientific research on restoration practice. The second part considers the dynamics and restoration of different ecosystems, ranging from arid lands to grasslands, woodlands, and savannahs, to forests and wetlands, to production landscapes. A summary chapter by the editors discusses the implications of theory and practice of the ideas described in preceding chapters. New Models for Ecosystem Dynamics and Restoration aims to widen the scope and increase the application of threshold models by critiquing their application in a wide range of ecosystem types. It will also help scientists and restorationists correctly diagnose ecosystem damage, identify restoration thresholds, and develop corrective methodologies that can overcome such thresholds.

Book Synopsis Mycorrhizal Associations Shape Complex Plant-soil Interactions in the Early Seedling Recruitment of Bornean Rainforest Trees by : Richard Maxfield Segnitz
Download or read book Mycorrhizal Associations Shape Complex Plant-soil Interactions in the Early Seedling Recruitment of Bornean Rainforest Trees written by Richard Maxfield Segnitz and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Biotic feedbacks between plants and soil fungi have been shown to influence seedling recruitment and plant community structure. This dissertation is principally concerned with how mycorrhizal associations influence such feedbacks as experienced by tropical tree seedlings, how soil fertility might change these interactions, and how the fungal communities that drive feedbacks assemble on seedling roots. While work in temperate forests suggests that there are consistent differences in plant-soil feedback between plants with arbuscular and ectomycorrhizal associations, it is unclear whether these differences exist in diverse tropical rainforests or how they may be impacted by heterogeneity in soil nutrients. In this dissertation, I address several current knowledge gaps by examining how plant-soil feedbacks operate in a diverse but ectomycorrhizal dominated rainforest in Northern Borneo. I conducted a shadehouse experiment (Chapters 1 & 2) using a design that allowed me to test whether the direction and strength of plant-soil feedback depends on a tree species' mycorrhizal association type, phylogenetically driven variation in the soil microbiota, and the fertility of the soil. I established a large scale multispecies shadehouse experiment in which the edaphic and biotic origins of soils were manipulated. I found that phylogenetically structured plant-soil feedbacks could influence seedling performance, but did so differently for ectomycorrhizal and arbuscular mycorrhizal seedlings (Chapter 1). Further, I found that soil resource availability changed the strength and direction of feedbacks for arbuscular mycorrhizal hosts but not ectomycorrhizal hosts. Using environmental DNA sequencing to characterize root-associated fungi in this experiment (Chapter 2), I showed that root-associated fungal communities differed at broad taxonomic scales across host mycorrhizal types but were similarly structured by host identity and soil type at finer scales. Further, I show that evolutionary relationships between seedlings and the overstory species that condition the soil can predictably affect root community structure, but that this effect differed depending on seedling mycorrhizal type, providing a possible mechanism by which plant-soil feedbacks is mediated. In my final chapter, I examine plant-soil feedbacks in a field experiment that focused on a single ectomycorrhizal seedling species. I explored how plant-soil feedbacks interact with density-dependent seedling mortality across the landscape in the field (Chapter 3). I found that seedlings of this species might weakly benefit from recruitment near conspecific adults and were likely not subject to conspecific negative density dependence typically thought to limit recruitment in tropical forests. I found that local scale density-dependence in seedling mortality did not vary with proximity to conspecific adults, suggesting that for this species the predominant effects on growth and mortality might be driven more by variation in the presence of beneficial soil biota than natural enemies. The results of this thesis collectively suggest that mycorrhizal associations of tropical trees play an important role in shaping how complex plant-soil interactions affect early seedling recruitment and, ultimately, tropical tree diversity. I found that species' mycorrhizal type shaped the feedbacks they experienced in a diverse Bornean rainforest, and also that mycorrhizal type could affect how the overstory canopy shapes root fungal communities. Further, the impact of overstory canopy composition on seedling growth can be dependent on both mycorrhizal type and edaphic heterogeneity.
