Six bacterial ecophysiological groups from Pleistocene sediment samples collected from two Romanian caves were identified and evaluated for their potential contribution to the interpretation of paleoclimate. Denitrifiers and nitrite oxidizers were present in the culture plates of all samples, the ammonia oxidizers were absent, and the iron-reducers were confirmed solely in the deepest sample of one of the caves. The aerobic mesophilic heterotrophsRead more
Speleothems are one of the most intensively explored continental archives for palaeoclimate variability. The parameters, however, that control speleothem petrography and its changes with time and space, specifically calcite crystal morphology and carbonate mineralogy, are still poorly understood. In order to shed light on processes and their products, precipitation experiments of recent carbonate crystals on watch glasses and glass plates were performedRead more
