Hydro-chemical cycle of forest ecosystem in the Norikura Highlands—2. Hydrologic and chemical cycle in coniferous forest and deciduous forest
forest ecosystem throughfall soil water dissolved elements base cations
2009/7/14
Hydro-chemical cycle of forest ecosystem was investigated in the Norikura Highlands. The investigation period was from June to October, 2003 and 2004. The precipitated water that reached to the forest...
Hydro-chemical cycle of forest ecosystem in the Norikura Highlands—1. Chemical characteristic and seasonal change of throughfall in forest ecosystem
forest ecosystem throughfall canopy leaching canopy uptake seasonal change

Because of precipitation serves as a major vehicle of nutrient input into the forest ecosystem, the accurate measurement of its volume and ion concentration is of prime importance in an evaluation of ...
Modelling the ecosystem effects of nitrogen deposition：Model of Ecosystem Retention and Loss of Inorganic Nitrogen
nitrogen deposition Ecosystem Retention
2009/6/8
A catchment-scale mass-balance model of linked carbon and nitrogen cycling in ecosystems has been developed for simulating leaching losses of inorganic nitrogen. The model (MERLIN) considers linked bi...
Vegetation dynamics and soil water balance in a water-limited Mediterranean ecosystem on Sardinia, Italy
Vegetation dynamics Mediterranean ecosystem soil water balance
2009/5/6
Mediterranean ecosystems are commonly heterogeneous savanna-like ecosystems, with contrasting plant functional types (PFTs, e.g. grass and woody vegetation) competing for water. Mediterranean ecosyste...
Ecosystem effects of thermal manipulation of a whole lake, Lake Breisjøen, southern Norway (THERMOS project)
Lake Breisjø en water chemistry Ecosystem effects thermal manipulation
2009/4/29
We conducted a 3-year artificial deepening of the thermocline in the dimictic Lake Breisjøen, southern Norway, by means of a large submerged propeller. An adjacent lake served as untreated refe...
Necessity to consider hydrological controls of biogeochemical cycling when developing a catchment-scale ecosystem model
hydrological controls catchment-scale ecosystem model biogeochemical cyclin
2009/4/2
In order to model the stream water chemistry in a forest catchment, the model should include functions describing both the biogeochemical cycle and the hydrological pathways as the transportation syst...
Biogeochemical model in forest ecosystem：Application and problem of PnET model
nutrient cycling stream chemistry simulation model process-based model carbon and nitrogen dynamics
2009/4/2
Biogeochemical processes are closely related to ecosystem functioning and the change in stream chemistry against various environmental changes. A process-based model that replicates the interaction be...
Features of Lake Takkobu ecosystem assessed by natural abundance of 13C and 15N
Kushiro Moor lake ecosystem

southern part. Seasonally, POM with high δ13C and low δ15N has appeared in summer, whereas the opposite is the case in spring and autumn. Horizontally, the summer POM with both higher δ13C and lower δ...
Physical and biogeochemical controls of microaggregate dynamics in a tidally affected coastal ecosystem
Physical biogeochemical controls
2014/5/4
Tidal flat ecosystems exhibit pronounced tidal currents that cause high loads of suspended matter (SPM) and intense sedimentation. To identify systematic patterns of tidal SPM dynamics and the signifi...
