δ15N systematics in two minerotrophic peatlands in the eastern U.S.: Insights into nitrogen cycling under moderate pollution

Autor: Martin Novak, Petra Pacherova, Emily M. Elliott, Ivana Jackova, Marketa Stepanova, Jan Curik, Bohuslava Cejkova, Frantisek Buzek, Eva Prechova, Ivana Valkova

Publikováno v: Global Ecology and Conservation, Vol 17, Iss , Pp - (2019)

Availability of reactive nitrogen (Nr; mainly ammonium, NH4+, and nitrate, NO3−) via precipitation and upwelling groundwater affects carbon (C) accumulation in peat deposits and biological greenhouse gas emissions. Isotope composition of Nr was stu

Isotope composition of dissolved organic carbon in runoff and peat leachates from a Central European wetland: Temporal and spatial variability in DOC sources

Publikováno v: CATENA. 173:217-225

In the near future, climate change will increasingly affect export of carbon (C) from peatlands. Terminal mineralization of dissolved organic carbon (DOC) is a source of greenhouse gases (carbon dioxide, CO2, and methane, CH4) for the atmosphere, and

15N study of the reactivity of atmospheric nitrogen in four mountain forest catchments (Czech Republic, central Europe)

Autor: Martin Novak, Filip Oulehle, Bohuslava Cejkova, Pavel Krám, Ivana Jackova, Frantisek Veselovsky, Jan Curik, Frantisek Buzek, Oldrich Myska

Publikováno v: Applied Geochemistry

Reactivity of atmospherically deposited nitrate (NO3−) and ammonium (NH4+) was investigated in three mountain forest catchments and one ombrotrophic peat bog located in the northern Czech Republic. The study sites are characterized by moderate to h

Isotope composition of NH3, NOx and SO2 air pollution in the Moravia-Silesian region, Czech Republic

Autor: V. Lollek, Ivana Jackova, Z. Lnenickova, R. Matolakova, Frantisek Buzek, F. Veselovsky, Bohuslava Cejkova, L. Hellebrandova

Publikováno v: Atmospheric Pollution Research. 8:221-232

The aim of this study is to compare the concentration and isotopic monitoring of sources of emission of NH3, NOx and SO2 in the industrial Moravia-Silesian region. We collected gases in tube-type passive samplers with acid and alkali treated filters

Relationship between nitrogen isotope ratios of NO3− and N2O in vertical porewater profiles through a polluted rain-fed peat bog

Autor: Eva Prechova, Gerhard Gebauer, Martin Novak, Arnošt Komárek, Bohuslava Cejkova, Daniela Fottova, Michael Thoma, Silvia Parra Suarez, Frantisek Veselovsky, Frantisek Buzek, Ivana Jackova, Marketa Stepanova, Vladimir Blaha, Ivana Valkova, Jan Curik

Publikováno v: Soil Biology and Biochemistry. 123:7-9

We report a combination of δ15N-NO3- and δ15N-N2O values along vertical porewater profiles through a Sphagnum-dominated, high-elevation peat bog. Our objective was to distinguish between N2O production from NO3− via denitrification and N2O consum
