Spatial variations of denitrification activity and the relative importance of controlling factors were determined using the isotope pairing technique in a seepage chain of Mediterranean flowthrough lakes (Ruidera lakes) and within a given lake in the

Nutrient pollution effects are not always apparent in freshwater sediments, because increase of N and/or P concentrations in recent sediments is also a consequence of sediment diagenesis. In the present work, two cores of sediment have been extracted

In a laboratory experiment, we examined the prolonged survival and behaviour of the benthic foraminiferan Globobulimina turgida under 3 simulated natural conditions: oxygenated with added nitrate, anoxic with added nitrate, and anoxic. The survival r

Benthic foraminifera are unicellular eukaryotes found abundantly in many types of marine sediments. Many species survive and possibly reproduce in anoxic habitats1, but sustainable anaerobic metabolism

Benthic foraminifera, single-celled eukaryotes, constitute a significant part of the living community in low-oxygen or even oxygen-depleted marine environments. Although the diversity is typically low and the dominance high, selected species appears

Studies on nitrogen dynamics in seepage lakes are seldom undertaken, yet our understanding of the complex pattern of the nitrogen (N) cycle is complicated by its temporal and spatial heterogeneity. This research investigated temporal variation in N c
