Por décadas, permeó una visión de la tecnología como una de las principales fuentes del ataque al medio ambiente y de su degradación. Hoy se le considera como un aliado para combatir los efectos negativos de la perenne negligencia ecológica humana. El uso de la tecnología para la implementación de estrategias innovadoras y eficaces en favor del medio ambiente, un hábitat seguro y sustentable se abordó en el Congreso Internacional sobre Sustentabilidad en los Hábitats, realizado en 2016. De este encuentro entre estudiantes, especialistas, autoridades y organizaciones civiles de América Latina, Asia y Europa emana este libro, que incluye dos ejes de relevancia global: los retos en ...
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.

An icon (from the Greek word "eikon," "image") is a wooden panel painting of a holy person or scene from Orthodox Christianity, the religion of the Byzantine Empire that is practiced today mainly in Greece and Russia. It was believed that these works acted as intermediaries between worshipers and the holy personages they depicted. Their pictorial language is stylized and primarily symbolic, rather than literal and narrative. Indeed, every attitude, pose, and color depicted in an icon has a precise meaning, and their painters--usually monks--followed prescribed models from iconographic manuals. The goal of this book is to catalogue the vast heritage of images according to iconographic type and subject, from the most ancient at the Monastery of Saint Catherine in the Sinai to those from Greece, Constantinople, and Russia. Chapters focus on the role of icons in the Orthodox liturgy and on common iconic subjects, including the fathers and saints of the Eastern Church and the life of Jesus and his followers. As with other volumes in the Guide to Imagery series, this book includes a wealth of color illustrations in which details are called out for discussion.

Few places in the world can claim such a diversity of species as the Gulf of California (Sea of Cortez), with its 6,000 recorded animal species estimated to be half the number actually living in its waters. So rich are the Gulf's water that over a half-million tons of seafood are taken from them annuallyÑand this figure does not count the wasted by-catch, which would triple or quadruple that tonnage. This timely book provides a benchmark for understanding the Gulf's extraordinary diversity, how it is threatened, and in what ways it isÑor should beÑprotected. In spite of its dazzling richness, most of the Gulf's coastline now harbors but a pale shadow of the diversity that existed just a h...
