Coral reefs are one of the most biologically diverse habitats in the world, host to an extraordinary variety of marine plants and animals. They are also one of the world''s most fragile and endangered ecosystems. The growth of mass tourism, combined with the boom in popularity of scuba diving, has brought these spectacular ecosystems to public attention across the planet. Coral reefs provide essential fish habitat, support endangered and threatened species, and harbor protected marine mammals and turtles. They are a significant source of food, provide income and employment through tourism and marine recreation, and offer countless other benefits to humans, including supplying compounds for pharmaceuticals. Yet coral reefs around the world are rapidly being degraded by a number of human activities, such as overfishing, coastal development, and the introduction of sewage, fertilizer, and sediment. "World Atlas of Coral Reefs "provides the first detailed and definitive account of the current state of our planet''s coral reefs. With its wealth of authoritative and up-to-date information, the finest maps available, and detailed descriptive texts and images by leading experts, this full-color volume will be a critical resource for anyone interested in these vital environments. "World Atlas of Coral Reefs "contains eighty-four full-page newly researched and drawn color maps, together with more than two hundred color photos illustrating reefs, reef animals, and images taken from space by NASA astronauts during the 2000 and 2001 space shuttle flights. The authors provide a wealth of information on the geography, biodiversity, and human uses of coral reefs, as well as details about thethreats to their existence. Prepared at the UNEP-World Conservation Monitoring Centre in Cambridge, England--the United Nations office responsible for providing authoritative information on the condition of global biodiversity--the "Atlas "will be a critical tool for scientists, students, policymakers, and planners at local, national, and international levels alike. Publication of the "World Atlas of Coral Reefs" is supported by international institutions including the United Nations Environment Programme; The Marine Aquarium Council, The International Coral Reef Initiative; ICLARM--The World Fish Cen

Intended for technicians, constructors, and engineers seeking a broad introduction to surveying, Geographic Information Systems (GIS), and Geographic Positioning Systems (GPS), this new text by Barry Kavanagh offers the needed coverage in a well-written presentation of principles and applications. "Some of the key features include: " Emphasis on the use of computer applications as a key tool in bringing together the diverse subjects covered in the book. The heavy use of illustrations helps the reader visualize the concepts and apply them to real-world situations. Extensive coverage of remote sensing methods. This state-of-the-art exploration of the theory and applications of geometrics recognizes the expansion and advances in the field "and" the broadening of the allied disciplines that have a direct interest in the newest technological approaches to geo-data collection, processing, analysis, management, and presentation. Exceptionally well-written by a teacher/surveyor manager with many years of experience, it provides a comprehensive "insider''s" view of what''s important, what works, and how it all fits together. Divided into three parts--Fundamentals, Remote Sensing, and Engineering Applications--it covers both traditional topics in surveying and the more recently developed topics in geographic information systems (GIS), global positioning (GPS) and airborne imagery, together with satellite imagery (remote sensing)--all with a focus on applications of interest to the fields of in civil, surveying, and geological engineering, physical geography, environmental, natural resources, etc. Features an appendix of 11 field projects involving the fundamentals of taping, leveling, and angle acquisition, and applications in data gathering, stake-outs for buildings, curves, and pipelines. An Introduction to Geometrics. Distance Measurement--Taping. Electronic Distance Measurement (EDM). Leveling. Angles and Directions. Transits/Theodolites. Traverse Surveys. Electronic Surveying Measurements. Topographic Surveying and Mapping. Geogramic Information Systems (GIS). Global Positioning Systems (GPS). Control Surveys. Land Surveying. Airborne Imagery. Satellite Imagery. Highway Curves. Construction Surveying. For anyone interested in the state-of-the-art theory and applications of Geomatics/Surveying.

La presente obra recoge un conjunto de trabajos originales, abordados principalmente desde la Biogeografía española sobre el paisaje, la evolución y la conservación del bosque mediterráneo y los humedales.Se trata de 93 contribuciones presentadas al X Congreso Español de Biogeografia, celebrado en Almagro en 2018, que han sido agrupadas en esta publicacion en seis grandes partes tematicas: Aportaciones destacadas; el Bosque mediterraneo evolucion y paisaje; Humedales, sistemas acuaticos y su dinamica; Biogeografia, conservacion y gestion; Tecnicas y metodos en investigacion y educacion en Biogeografia, y por ultimo, una parte que recoge aquellas investigaciones que estan aun en proceso de desarrollo.Inventarios de campo, fuentes documentales, tecnicas paleobiologicas, tecnologias de la informacion geografica en sentido amplio y, pro primera vez, las aportaciones desde la didactica y la divulgacion, son las tecnicas que mas emplean los investigadores en los trabajos presentados en esta obra.
