Aim of study: To quantify the biomass and carbon stored in main ecosystem components Pinus radiata D. Don plantations across an age sequence Pampean region Argentina.
 Area Plantations were established on non-agricultural land, southeast province Buenos Aires.
 Material methods: Fourteen sites selected plantations, 9-, 13-, 15-, 19- 21-years-old, a first forest rotation. Forty-two tre...

Radiata pine (Pinus radiata D. Don) and Douglas fir (Pseudotsuga menziesii (Mirb.) Franco.) seedlings were subjected to waterlogging periods of 1, 2, 4, 3, and 16 weeks. Phosphorus-32 uptake and succinic dehydrogenase activity of waterlogged mycorrhizas were measured and compared with non-waterlogged mycorrhizas. After 2 weeks of waterlogging Douglas fir mycorrhizas absorbed less P than control...
