Paleolimnological research only started in Uruguay in 1999 in the frame of the German-Uruguayan Academic Cooperation Program (DAAD-UDELAR). Research focused in costal lagoons and special attention was paid to the relationship between trophic development and sea level changes. Paleolimnology was also used as tool to assess human impact on aquatic water bodies and to provide a basis for the development of a management plan. Concomitantly, diatom taxonomy was also developed as diatoms are very well established indicators of paleoenvironmental change. In this sense, about 70 diatom species have been described as new for science.
