Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the dynamical processes influencing the structure of coral communities, some of the most biologically diverse communities on earth. A variety of biological and physical processes operating across an enormous range of spatiotemporal scales are highlighted (e.g., niche partitioning, biological interactions, disturbance phenomena, large-scale tectonic, eustatic, climatic, and oceanographic processes). The focus on the community provides a framework for presenting some of the best examples from the literature using multiple taxonomic groups (e.g., corals, fishes, encrusting invertebrates).

Available in PDF, EPUB and Kindle. Book excerpt: Coral reefs are acknowledged for the beauty of their organisms, which has made this natural ecosystem one of the most appreciated on Earth. It is believed to be the richest in terms of species diversity and species interactions, at least in theory since there is yet much documentation work to be done. Indeed, the paradox is that of the estimated one million species living in this ecosystem globally, only 10% of them have been described. To date, most of the coral reef studies have focused on the most peculiar and fabulous groups, such as corals and fishes, although most of the diversity is usually represented by small, colored, camouflaged, hidden, and crypto organisms from all kingdoms of life. The mystery of their diversity, ecology, biology, and importance in the functioning of coral reefs motivate many scientists to dive, all around the world, in order to discover, name, and appreciate such a fascinating, but unfortunately overlooked, component of nature. This book is a very nice illustration of the charm of the coral-associated fauna.

Available in PDF, EPUB and Kindle. Book excerpt: Coral reef benthic communities form a critical part of coral reef systems linked to human societies. Using a complex systems approach that highlights inter-dependencies between substrate-bound organisms competing for space and ecological patterns that constrain demographic and competitive processes, the coral reef benthic system is dynamically characterized from the coral colony scale to the island scale with numerical models and data analysis techniques. In Chapter 2, I quantify and analyze reef-building coral colony change with colony areal coverage and longevity. Using over 4,300 Caribbean colonies measured over 4.5 years, proportional change in area of smaller colonies was found to be greater than for larger ones, following expectations of allometrically constrained growth. In terms of longevity, larger colonies lived longer than smaller ones, an effect that was lessened by colony fission and fusion, indicating these processes could confer a survival advantage. Overall, the results support a critical dependence of coral colony demography on size and morphology. In Chapter 3, I analyze the effect of spatial patterning on reefscape change over decadal time spans. Using a cellular model that simulates the interactions between four benthic functional groups, I find that reefscape (dm-km) dynamics can be categorized robustly with four distinct stages, including a transient stage dominated by nonlinear competitive dynamics. Increasing levels of colony spatial aggregation (clumpiness) results in a longer duration transient stage, prolonging arrival to the steady state. Results have potential implications for reef monitoring and restoration; for example, high initial aggregation slows loss in degraded reefs and low initial aggregation accelerates growth in healthy reefs. In Chapter 4, I describe derivation of a novel island-scale continuum coral reef model based on the cellular model used in Chapter 3. Numerical solutions of the resulting twelve coupled nonlinear partial differential equations (describing change of functional group fractional covers, nondimensional boundary lengths between functional groups, mean colony size and fish biomass density) match key aspects of the cellular model, as well as producing emergent patterns that go beyond what is observed in the cellular model. In Chapter 5, I describe a novel framework for using these results to build models of coupled societal-reef systems.

Available in PDF, EPUB and Kindle. Book excerpt: The overarching objective of this dissertation was to improve our knowledge of the relationship between seascape heterogeneity and diversity of stony coral assemblages across spatial scales. Coral communities on patch reefs in three regions of the Caribbean were used as a model system to investigating this relationship because patch reef heterogeneity could be readily quantified within the seascape using remote sensing and image analysis techniques. I began with a theoretical approach, exploring the origins of observed species diversity among coral communities at increasing spatial scales. Hierarchical sampling and null models revealed that coral diversity was governed by non-random processes at local- (10s of meters) and meso- (100s of m) scales. Spatial autocorrelation and reef heterogeneity were then investigated as potential mechanistic drivers of these non-random diversity patterns. I found limited support for spatial drivers. However, beta diversity was significantly correlated to metrics of reef heterogeneity (measured as reef size, spatial configuration, and complexity), indicating that differences in reef heterogeneity were making a disproportionate contribution to the overall coral community diversity. The relationship between corals and reef heterogeneity was found to be both scale-dependent and region dependent. This theoretical approach was followed by a manipulative approach using an existing artificial patch reef array to experimentally test the influence of reef spatial configuration and topographical complexity on local diversity. Corals were most sensitive to reef size and secondarily reef configuration within the seascape. Unlike reef fishes, reef complexity did not emerge as a strong predictor of the coral community composition in either the observational data or the experimental manipulation. These observational and experimental explorations of the relationship between corals and habitat reveal that intra-habitat variability (i.e. differences between patch reefs) can influence the diversity and abundance of corals. I then focused on applying this improved theoretical understanding towards improving coral management efforts. I present a new methodology to assess the efficacy of marine reserve effects by controlling for natural seascape variation within and beyond the reserve boundary, and I quantified the bias of underestimating coral diversity by using conventional reef monitoring protocols that ignore differences in reef size. In conclusion, I demonstrate empirically that seascape attributes of reef heterogeneity can contribute to coral diversity at relatively small spatial scales (

Book excerpt: Reef ecosystems extend throughout the tropics. Exploited by small-scale fishers, reefs supply food for millions of people, but, worldwide, there are growing worries about the productivity and current state of these ecosystems. Reef fish stocks display many features of fisheries elsewhere. However, habitat spatial complexity, biological diversity within and among species, ecosystem intricacy and variable means of exploitation make it hard to predict sustainable modes and levels of fishing.

Available in PDF, EPUB and Kindle. Book excerpt: In this book, contributors from diverse backgrounds take a first step toward an integrated view of reefs and the significance of their recent decline. More than any other earth system, coral reefs sit at a disciplinary crossroads. Most recently, they have reached another crossroads - fundamental changes in their bio-physical structure greater than those of previous centuries or even millennia. Effective strategies to mitigate recent trends will require an approach that embraces the myriad perspectives from across the scientific landscape, but will also need a mechanism to transform scientific understanding into social will and political implementation.

Download or read book Resilience and the Behavior of Large Scale Systems written by Lance H. Gunderson and published by Island Press. This book was released on 2012-06-22 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists and researchers concerned with the behavior of large ecosystems have focused in recent years on the concept of "resilience." Traditional perspectives held that ecological systems exist close to a steady state and resilience is the ability of the system to return rapidly to that state following perturbation. However beginning with the work of C. S. Holling in the early 1970s, researchers began to look at conditions far from the steady state where instabilities can cause a system to shift into an entirely different regime of behavior, and where resilience is measured by the magnitude of disturbance that can be absorbed before the system is restructured. Resilience and the Behavior of Large-Scale Systems examines theories of resilience and change, offering readers a thorough understanding of how the properties of ecological resilience and human adaptability interact in complex, regional-scale systems. The book addresses the theoretical concepts of resilience and stability in large-scale ecosystems as well as the empirical application of those concepts in a diverse set of cases. In addition, it discusses the practical implications of the new theoretical approaches and their role in the sustainability of human-modified ecosystems. The book begins with a review of key properties of complex adaptive systems that contribute to overall resilience, including multiple equlibria, complexity, self-organization at multiple scales, and order; it also presents a set of mathematical metaphors to describe and deepen the reader's understanding of the ideas being discussed. Following the introduction are case studies that explore the biophysical dimensions of resilience in both terrestrial and aquatic systems and evaluate the propositions presented in the introductory chapters. The book concludes with a synthesis section that revisits propositions in light of the case studies, while an appendix presents a detailed account of the relationship between return times for a disturbed system and its resilienc. In addition to the editors, contributors include Stephen R. Carpenter, Carl Folke, C. S. Holling, Bengt-Owe Jansson, Donald Ludwig, Ariel Lugo, Tim R. McClanahan, Garry D. Peterson, and Brian H.

Available in PDF, EPUB and Kindle. Book excerpt: Kupe and the Corals is the story of Kupe, a young boy who undertakes an amazing voyage of discovery to learn about corals and the importance of coral reefs to all of the many animals that depend upon them. One night while he is fishing with his father, Kupe observes an astonishing event, thousands and thousands of tiny “bubbles” rising to the surface of the waters in the lagoon near where he lives. Kupe is amazed by this sight and wants to learn more about the “strange pink bubbles” that he has captured in an old jam jar. Kupe visits with an elder from his village and a scientist from the nearby marine lab in an attempt to learn more about what he has seen. During his conversations, Kupe learns that what he has captured are tiny coral larvae, baby corals that are produced in the millions over just a few nights each year by the adult corals living in the lagoon. Kupe then goes on to learn more about how corals grow and the importance of corals in building the reefs that provide homes for all of the other wonderful animals that he sees while snorkeling in the lagoon. Now, realizing how important the larvae he has captured are to the health of the coral reef, Kupe happily returns his larvae to the sea. Kupe and the Corals, is the sixth book in the Long Term Ecological Research Network Series.

This book was released on 2009-09-23 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mangrove forests, seagrass beds, and coral reefs are circumtropical ecosystems that are highly productive, and provide many important biological functions and economic services. These ecosystems cover large surface areas in the shallow tropical coastal seascape but have suffered from serious human degradation, especially in the last few decades. Part of their diversity, productivity, and functioning seems to be based on their juxtaposition. Especially in the last decade significant advances have been made on new insights into their ecological connectivity. This authoritative book provides a first-time comprehensive review of the major ecological interactions across tropical marine ecosystems that result from the mutual exchange of nutrients, organic matter, fish, and crustaceans. A group of leading authors from around the world reviews the patterns and underlying mechanisms of important biogeochemical and biological linkages among tropical coastal ecosystems in 15 chapters. Included are chapters that review cutting-edge tools to study and quantify these linkages, the importance of such linkages for fisheries, and how tropical ecosystems should be conserved and managed for sustainable use by future generations. The book uses examples from all over the world and provides an up-to-date review of the latest published literature. This book is a ‘must read’ for professionals working on the conservation, management, and ecology of mangrove, seagrass and coral reef ecosystems.
