Researchers at the University of Rio Grande have just published a Thematic Volume at Marine Biology Research with integrated results of our long term studies at the Patos Lagoon Estuary (PLE) in southern Brazil. The complete volume is available at: http://www.tandfonline.com/toc/smar20/13/1?nav=tocList. PLE is one of the coastal sites in the Brazilian Long Term Ecological Research Programa (BLTE), and has been supported by the Brazilian Science and Tecnhology agency CNPq. PLE has been supported since its conception 20 years ago, and has significantly improved our knowledge on the variability of the biota and its causes. The long term study has contributed to the conservation and appropriate management of the Patos Lagoon Estuary and its marine coastal adjacent areas.
