Abstract
Soils in temperate forests ecosystems are the greatest terrestrial CH4 sink globally. Global and regional circulation models predict decreased average rainfall, increased extreme rainfall events and increased temperatures for many temperate ecosystems. However, most studies of soil CH4 uptake have only considered extended periods of drought rather than an overall decrease in rainfall amount. We measured soil CH4 uptake from March 2010 to March 2012 after installing passive rainfall reduction systems to intercept approximately 40% of throughfall in a temperate broadleaf evergreen eucalypt forest in south-eastern Australia. Throughfall reduction caused an average reduction of 15.1 ± 6.4% (SE) ..
