A quantitative method of palaeolake-level reconstruction using ostracod assemblages : an example from the Bolivian Altiplano

This paper provides quantitative information concerning the response of ostracods to environmental variability in order to reconstruct past environments. Ostracod faunas from modern sediments of Bolivian lakes and swamps were studies. Ostracod distribution is controlled by several ecological characteristics such as lake-level and water chemistry. Statistical results indicate that three transfer functions (on water depth, Total dissolved Salts and water in Mg/Ca ratio) can be developed, from ostracod species frequencies in lacustrine sediments, with some restrictions for the tow last ones (Resume d'auteur)

Late Quaternary palaeohydrology of Lake Huinaymarca (Bolivia)

L'analyse des associations d'ostracodes présents dans les échantillons prélevés dans les sédiments du lac Huinaymarca permet de retracer l'évolution hydrobiologique du lac (variation du niveau lacustre, variation de l'oxygénation par rapport à la position de la thermocline, interconnections avec les différents bassins du lac) au cours des dix derniers millénaire

Ostracoda and global events

The environmental mechanisms directly responsible for variations recorded in the ornamentation of ostracos are well known. They concern mainly the carbonate equilibrium at the water/sediment interface (reticulation phenomenon sensu lato) and the impact of the input of fine-grained and all allochthonous matter on biotopes (nodation and microconation phenomena) (Resume d'auteur)
