| This paper examines the relationship between history and science with regard to the marine environment. It argues that historians and scientists should collaborate to reconstruct past ecosystems. Such collaboration to shed some light on the reasons why the life in the oceans appears as it does today. With this objective in view, a global research program has been established. The History of marine animal populations (HMAP) addresses four basic questions. (1) How has the extent and diversity of these populations changed over the last 2000 years? (2) Which factors have influenced these change? (3) What has been the anthropogenic and biological significance of these changes? (4) What has been the interplay of changing marine ecosystems and human societies?... |

| The marine areas of Uruguay consist of the Río de la Plata estuary and the adjacent shelf and slope, part of the Subtropical Convergence Ecosystem. In this paper, the main advances in the knowledge of marine life in these areas (the known) are reviewed in order to discuss future lines of research (the unknown). Information has been separately analysed for the plankton, nekton, and benthos in each of 3 areas-the littoral, the shelfs and the "open ocean". Current knowledge of marine life is uneven among the groups and areas. In the case of the plankton, research has concentrated on the near-shore waters and focused on taxonomy and distribution. Little is known about the responses of organisms to environmental variability and about biological processes. The... |
