Dear Colleagues, We are pleased to announce that a new chapter titled: Marine Environment and Public Health is available. The chapter has been published by InTech, inside the book Biodiversity Conservation and Utilization in a Diverse World (DOI: 10.5772/3330). We present some results of bacteriological surveys (Aeromonadaceae and Vibrionacea species) that have been carried out with many specimens of marine mammals, seabirds and sea turtles from Brazilian coast. It can be downloaded here: http://www.intechopen.com/books/biodiversity-conservation-and-utilization-in... DOI: 10.5772/48412 Or here: http://www.intechopen.com/books/biodiversity-conservation-and-utilization-in... http://dx.doi.org/10.5772/48412 Brief introduction: This book "Biodiversity Conservation and Utilization in a Diverse World" sees biodiversity as management and utilization of resources in satisfying human needs in multi-sectional areas including agriculture, forestry, fisheries, wildlife and other exhaustible and inexhaustible resources. Its value is to fulfill actual human preferences and variability of life is measured by amount of genetic variation available. In viewing diversity as an ultimate moral value, one is faced with a situation in environmental preservation in order to allow components of total diversity to flourish and constitute a threat to continuous existence and decrease total diversity. The overall importance described economic benefits from bio-diversity, though difficult to measure and varying, but are limited on a local scale, increase on a regional or national scale and become potentially substantial on a transnational or global scale. Best regards to all, Salvatore ------------------------------------------------------- Salvatore Siciliano Escola Nacional de Saude Publica/FIOCRUZ Rio de Janeiro, Brazil & IMMAR/GEMM-Lagos
