Project

Calcium tolerance in Sphagnum, its physiological and genetic backgrounds, and consequences in mire ecology (GAP505/10/0638)

This project addresses the issue of calcium tolerance in Sphagnum that has been virtually neglected as opposed to other aspects of Sphagnum ecology. Its understanding strategies in fens presently changed by Sphagnum expansi...

Isotope constraints on microbial N2-fixation in ombrotrophic peat bogs (GA16-18079S)

-fixation is triggered off even at relatively high N inputs into Sphagnum (10 kg/ha/yr. At two sites, where deposition brings isotopically light N, we found Sphagnum that is isotopically heavier than N2. If Sphagnum contain...

Nitrogen fixation in polluted Czech peat bogs Reconciling high N accumulation rates based on 210Pb dating with low 15N2 uptake and low P availability (GA24-12596S)

Availability of reactive nitrogen (Nr) is a key control of carbon sequestration in wetlands. To complement the metabolic demands of Sphagnum in pristine bogs, diazotrophs supply additional Nr via biological nitrogen fixation (BNF). Since bre...

How do communities of different organisms respond to insularity in a fragmented mire habitat? (GA24-10844S)

Fens are naturally insular habitats that have recently experienced rapid deterioration. To effectively protect and restore them, we need to know which processes of island biogeography are essential for their key biotic communities. Our goal is to tes...
