Heikki Poutanen

Kuoron rooli messussa on ollut aina hyvin huomattava. Schola cantorum lauloi messun keskeiset laulut jo 700-luvulla. Neljä vuosisataa myöhemmin, kun moniääninen laulu tuli vähitellen messuun, kuoron asema vahvistui ja oli välttämätön. 1300-luvulta lähtien saatettiin säveltää messun koko ordinarium kuorolle.

Holocene carbon dynamics and atmospheric radiative forcing of different types of peatlands in Finland

Paul Mathijssen

Peatlands contain approximately a third of all soil carbon (C) globally and as they exchange carbon dioxide (CO2) and methane (CH4) copiously with the atmosphere, changes in peatland C budgets have a large impact on the global C balance and on the concentration of greenhouse gases in the atmosphere. How peatlands will react to future climate changes, however, is still relatively uncertai...
