Abstract
Under the Meeting IX Caribbean Biodiversity Congress, abstracts can be sent for participating at the Symposium: APPROACH TOWARD A SUSTAINABLE BIOMONITORING OF FRESHWATER ECOSYSTEMS’ HEALTH BASED ON OXIDATIVE STRESS MOLECULAR BIOMARKERS

Physical-chemical and chemical determinations currently employed for monitoring pollution are mainly based on qualitative and quantitative information about contaminants and freshwater quality, generally at high costs, providing indirect information and no direct biological interpretation of damage for these ecosystems. Thus, molecular biomarkers constitute a first approach for gathering information about cell damage and antioxidant response, early signals of ecosystems disorders. The main goal of the Symposium is focussed to generating debate about advantages using molecular biomarkers approach for biomonitoring ecosystems' health with respect to conventional chemical and physical-chemical methods. Thoughts must be focused about appropriateness and relevance of gathered information, nature of analysis to be done, costs and period for assays establishment during decision-making process; which allows a closer assessment of biological damage in ecosystem health introduced by pollutant sources and their environmental impact.

En el marco del IX Congreso de la Biodiversidad Caribeña se podrán enviar resúmenes para presentar en el Simposio: ACERCAMIENTO HACIA UN BIOMONITOREO SOSTENIBLE DE LA SALUD DE ECOSISTEMAS DULCEACUICOLAS SOBRE LA BASE DE BIOMARCADORES MOLECULARES DEL ESTRÉS OXIDATIVO.

Los métodos químicos que se emplean actualmente para el monitoreo de la contaminación se basan fundamentalmente en la detección cualitativa y cuantitativa de los contaminantes. Son métodos generalmente costosos y proveen información indirecta, muchas veces sin una interpretación biológica del daño sobre estos ecosistemas. En tales condiciones, los marcadores moleculares constituyen una primera aproximación en la recopilación de información sobre el daño celular y la respuesta antioxidante, señales tempranas de alteraciones en los ecosistemas. El objetivo del Simposio es explicar las ventajas del biomonitoreo de la salud de los ecosistemas dulceacuícolas con métodos bioquímicos respecto a los métodos químicos y físico-químicos convencionales sobre la base del debate acerca de la pertinencia y relevancia de la información que brindan estos métodos, tipo de análisis a realizar, costos y momento en el que se establecen los ensayos para la toma de decisiones, permitiendo así una evaluación más cercana al daño biológico que introducen las fuentes contaminantes en la salud de los ecosistemas y su impacto ambiental.
