Book Description
One aim of the physical sciences has been to give an exact picture of the material world. One achievement of physics in the twentieth century has been to prove that that aim is unattainable . . . . There is no absolute knowledge. And those who claim it, whether they are scientists or dogmatists, open the door to tragedy. All information is imperfect. We have to treat it with humility. Bronowski (1973) The Ascent of Man It seems particularly appropriate to us to begin this book with Jacob Bronowski's passionate message firmly in mind. Those who set out to construct numerical models, especially ones that are mechanistic and essentially deterministic, must work always with this awareness as a backdrop for their efforts. But this is also true for the most meticulous physiologist or observant naturalist. We are all dealing with simplifications and abstractions, all trying to figure out how nature works. Unfortunately, this common pursuit does not always lead to mutual understanding, and we have become increasingly aware over the past six years that many ecologists feel a certain hostility or at least distrust toward numerical modeling. In a number of cases the reasons for such feelings are personal and very understandable-hard gotten data skimmed off by someone with little appreciation for the difficulties involved in obtaining reliable measurements, grandiose claims of predictability, the tendency for some model builders to treat other scientists as number-getters whose research can be directed in response to the needs of the model, etc.

Book Description
Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental settings, biotic components and structure of the system, considers trophic processes and energy flow, evaluates the modifying influence of natural and human perturbations, and suggests management needs. Although the focus of the book is on basic ecological research, the results have application for coastal managers.

Book Description
The book presents a collection of large-scale network-modeling studies on coastal systems in Latin America. It includes a novel description of the functioning of coastal complex ecosystems and also predicts how natural and human-made disturbances percolate through the networks. Coastal areas belong to the most populated ecosystems around the globe, and are massively influenced by human impacts such as shipping, mining, fisheries, tourism, pollution and human settlements. Even though many of these activities have facilitated socio-economic development, they have also caused a significant deterioration in natural populations, communities and ecosystems worldwide. Covering coastal marine ecosystems of Latin America such as the NE and SE Pacific, NW Atlantic and Caribbean areas, it discusses the construction of quantitative (Ecopath-Ecosim-Ecospace and Centrality of Node Sets) and semi-quantitative (Loop Analysis) multispecies trophic-network models to describe and assess the impacts of natural and human interventions like pelagic and benthic fishing as well as natural events such as El Niño, and La Niña. The book also features steady state (and/or near moving equilibrium) and dynamical models to support the management of exploited organisms, and applies and quantifies macroscopic indices, based on Ascendency (Ulanowicz) and Local Stability (Levins ́ Loop Analysis). Further, it discusses the determination of the Keystone Species Complex Index, which is a holistic extension of the classical concept of Keystone Species (Paine), offering novel strategies for conservation monitoring and management.

Book Description
Ecosystem-Based Management (EBM) is one of the most holistic approaches to protecting marine and coastal ecosystems as it recognizes the need to protect entire marine ecosystems instead of individual species. After decades of pollution, habitat degradation and overfishing, now climate change and ocean acidification threaten the health of the ocean in unprecedented way. Environmental Management of Marine Ecosystems illustrates the current status, trends, and effects of climate, natural disturbances and anthropogenic impacts on marine ecosystems. It demonstrates how to integrate different management tools and models in an up-to-date, multidisciplinary approach to environmental management. This indispensable guide provides several case studies from around the world and creates a framework for identifying management tools and their applications in coral reefs, fisheries, migratory species, marine islands and associated ecosystems such as mangroves and sea grass beds. It discusses the physical and chemical compositions of marine ecosystems along with the threats and actions needed to protect them. The application of model framework to several contemporary management issues include the modelling of harmful algal bloom dynamics, understanding the dispersal of sea lice, and the possible impacts on intertidal communities of the provision of novel offshore habitat. The results of extensive research by an international team of contributors, the Environmental Management of Marine Ecosystems is designed to inform scientists, practitioners, academics, government and non-government policymakers on the particularities of marine ecosystems and assist them in understanding the EBM approaches in means of mitigation and adaptation of human activities that result in sustainability. These practices will help change the current methodologies used for resource assessment and the future regulations of marine resources.

Book Description
The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Book Description
This book applies the ‘ecosystem services’ framework to coastal environments, showing how it could facilitate an adaptive management strategy. The contributors describe a decision support system (DSS) based on the 3 Ps – pluralism, pragmatism and precaution – that leads to a more flexible, ‘learn by doing’ approach to the stewardship of coastal environments. The book lays out a “Balance Sheets Approach” to formatting, interrogating and presenting data and findings. The opening chapter defines coastal zones, their characteristics and natural resources, and describes their complex and dynamic nature. The chapter shows that large-scale trends and pressures have led to a global loss of 50% of marshes, leading to significant declines in biodiversity and habitat. Part I presents a conceptual framework, describes natural science techniques for coastal and shelf modeling, and describes valuation of ecosystem services. Part II outlines practical ecosystem indicators for coastal and marine ecosystem services, reviews literature on valuation of coastal and marine ecosystem services, explores scenarios, outlines marine and coastal ecosystem services data and offers tools for incorporating data into decision-making. PART III offers case studies including one linking the ecosystem services of Marine Protected Areas to benefits in human wellbeing; and another on valuing blue carbon captured by oceans and coastal ecosystems. Also included are a study of managed realignments and the English coastline and their value estimate transferability; and studies of the impact of jellyfish blooms on recreation in the UK and on fisheries in Italy.
