Dinitrogen fixation associated with shoots of aquatic carnivorous plants: Is it ecologically important?

Background and Aims Rootless carnivorous plants of the genus Utricularia are important components of many standing waters worldwide, as well as...

What do results of common sequential fractionation and single-step extractions tell us about P binding with Fe and Al compounds in non-calcareous sediments?

Correct identification of P forms together with their main Fe and Al binding partners in non-calcareous sediments is of crucial importance for...

Light as a factor affecting the concentration of simple organics in the traps of aquatic carnivorous Utricularia species

Rootless aquatic carnivorous Utricularia plants exude significant amounts of photosynthates into the trap fluid, where they have been shown to...

Ecological implications of organic carbon dynamics in the traps of aquatic carnivorous Utricularia plants

Rootless aquatic carnivorous Utricularia exude up to 25% of their photosynthates into the trap lumen, which also harbours a complex microbial...

Aluminum control of phosphorus sorption by lake sediments

Release of reactive (phosphate-like) phosphorus (P) from freshwater sediments represents a significant internal P source for many lakes. Hypolimnetic...

Natural inactivation of phosphorus by aluminum in atmospherically acidified water bodies

Atmospheric acidification of catchment–lake ecosystems may provide natural conditions for the in-lake control of P cycling. This process is based...

Phosphorus inactivation by aluminum in the water column and sediments: Lowering of in-lake phosphorus availability in an acidified watershed-lake ecosystem

Acid precipitation has been shown to reduce phosphorus (P) outputs from terrestrial sources. We present field evidence that the in-lake P cycle may...
