The first tourist destinations were primarily consolidated in the early twentieth century. Since then, tourism has undergone significant changes in its economic and social components. Over time, many of these destinations have now come to represent 'mass tourism' and are the subject of many studies on the impacts of tourism and competitiveness policies. The conclusions of these studies point to the need for new perspectives and strategies ranging from adaptation to new contexts to a radical change in targets. Concepts such as 'sustainability', 'nature', 'biodiversity' or 'climate change' have now been added to the tourism industry with varying degrees of knowledge and skill. These offer a gr...
First published in 1979, this guide has become the standard resource for scientists, divers, and spearfishers interested in the fishes of the tropical Pacific Coast. The authors have revised and updated this edition to include the most current taxonomic information, additional species descriptions, and new illustrations.
This new book takes us through a journey from early life to modern agriculture. The thirty eight authors present current studies on the interrelation of plants-animals. This topic has always fascinated man, as evidenced even by the first chapters of Genesis. The world of aqueous and terrestrial fauna appeared on early earth only after the flora covered the areas with the green pigmentation. Almost all life depends upon sunlight via the photosynthesis of the botanical world. We read abut the harnessing of bee pollination of crops to make it an essential component of modern agriculture endeavor. Some plants seduce insects for pollination by their appearance (e.g., disguised orchids entice visitors); there is the production of sweet nectar as a bribe in flowers to attract bees, butterflies, and honey-sucking birds. A particular outstanding phenomena are the carnivorous plants that have developed trapping and digesting systems of insects and higher animals.
