Resumen del producto

Harmful algal blooms (HABs) are becoming more extensive geographically and in extent of time, and the causes are not yet fully understood. It has been suggested that apart from natural causes, there is a relationship with global climate change and anthropogenic pollution in coastal waters, but the impact of each factor has not been established. A raise in global atmospheric temperature, with the consequential increase in ocean temperatures has been pointed out as one of the main reasons for HAB expansion; yet, many coastal changes generated by human activities, such as land alteration, nutrient enrichment due to agriculture, industry and urban waste also show a relationship with this expansion. In Mexico, HAB studies are still scarce, including their causes and consequences, and it is imperative to reinforce research and monitoring strategies since their impacts are not only reflected in ecosystem damage but also in socio-economic losses in tourism, public health and monitoring costs. Nevertheless, we have now information about several toxinproducing species in our coasts, information on recent events, and their plausible relationship with hydrological conditions and coastal pollution. To better understand this phenomenon and to be able to act accordingly, inter-institutional and multidisciplinary collaborative work among researchers, environmental and health authorities, and general population is urgent. To contribute with this knowledge, we prepared a review of the research held in Mexico on harmful algal blooms and their probable relationship with coastal pollution and climate change.[br]
