Chronic nitrogen addition causes a reduction in soil carbon dioxide efflux during the high stem-growth period in a tropical montane forest but no response from a tropical lowland forest on a decadal time scale

Atmospheric nitrogen (N) deposition is rapidly increasing in tropical regions. We studied the response of soil carbon dioxide (CO2) efflux to long-term experimental N addition (125 kg N ha−1 yr&...
Direct Rhenium-Osmium age of the Oxfordian-Kimmeridgian boundary,Staffin bay,Isle of Skye,U.K.,and the Late Jurassic time scale
Direct Rhenium-Osmium age Oxfordian-Kimmeridgian boundary Staffin bay Late Jurassic time scale
2009/12/2
Rhenium-Osmium (Re-Os) dating of black shale of the proposed Global Stratotype Section and Point (GSSP) for the Oxfordian-Kimmeridgian boundary, at Staffin Bay, Isle of Skye, U.K., yields an age of 15...
Evolution of the 2006–2007 El Nio:the role of intraseasonal to interannual time scale dynamics
Evolution 2006–2007 intraseasonal to interannual time scale dynamics
2010/1/27
We describe development of the 2006–2007 El Ni?o, which started late, ended early and was below average strength. Emphasis is on the interplay between large scale, low frequency (i.e., seasonal-to-int...
Time-scale invariances in preseismic electromagnetic radiation,magnetization and damage evolution of rocks
Time-scale invariances preseismic electromagnetic radiation magnetization damage evolution

We investigate the time-scale invariant changes in electromagnetic and mechanical energy releases prior to a rock failure or a large earthquake. The energy release processes are caused by damage evolu...
