Modelling denitrification including the dynamics of denitrifiers and their progressive ability to reduce nitrous oxide: comparison with batch experiments

Nitrous oxide contributes to the global greenhouse effect and affects the chemistry of O 3 in the upper troposphere and lower stratosphere. To define a relevant model for microbial NO 3 - and N 2 O reductions in soil and estimate the parameters involved, we propose a method combining measurements of anaerobic soil slurry and simulations of NO 3 - and N 2 O reductions, including non-enzymatic competition between NO 3 - and N 2 O as electron acceptors and the microbial dynamics of two denitrifier groups that are either able or unable to reduce N 2 O. Three models varying in the description of soil capability to reduce N 2 O through denitrification were assessed. The procedure was applied on a…

Hepatics and anthocerotes of the mediterranean, an annotated checklist

The names of all hepatics and anthocerotes published to the end of may 2007 in the Mediterranean countries and Bulgaria are compiled in an annotated checklist list. The list comprises accepted names and synonyms and provides explanatory annotations for ambiguous and disputed names. A total of 403 accepted species and 12 infraspecific taxa are reported from the area.
