Process-based modelling of N losses from terrestrial ecosystems
(2010-05-20)
Nitrogen (N) loss to atmosphere and ground water can contribute to environmental destruction, by N emission as the greenhouse gas nitrous oxide (N2O) and by leaching of N to contamination and eutrophication of water. Dynamic ...

Calceolaria L., Jovellana Ruiz & Pav., and Porodittia G. Don (=Stemotria Wettst. &
Harms) toghether constitute the family Calceolariaceae consisting of approximately
300 species distributed manily in South America. The ...
Effects of pharmaceuticals on natural microbial communities: Tolerance development, mixture toxicity and synergistic interactions
(2010-09-17)
Due to our extensive use of pharmaceuticals, low concentrations (picomol-nanomol/L) end up in the aquatic
environment. Antibiotics comprise a group of pharmaceuticals specifically designed to disrupt microbial ...
Land use effects on nitrous oxide emission from drained organic soils
(2010-05-21)
Since industrialisation, the atmospheric concentration of greenhouse gases (GHG) has increased significantly. The most important anthropogenic GHGs are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). N2O is ...
Phylogenetic and phyloclimatic inference of the evolution of Potentilleae (Rosaseae)
(2010-05-20)
Polyploidization has occurred many times during the evolution of angiosperms. Allopolyploidization is believed to be the process behind many of these genome duplications, and has resulted in a genetically diverse angiosperm ...
