Dynamic interactions between CO2 efflu, sap flow and internal CO2 concentration in tree stems: implications towards the assessment of actual stem respiration
… order to verify whether forests are net sinks of CO2, it is necessary to accurately quantify the photosynthesis (CO2 uptake) and respiration (CO2 release) by trees. The objective of the Ph.D. was to perform fundamental research on dynamics in respiration of tree stems. It became clear that …

Tree Growth and Carbon Balance in a Temperate Forest Exposed to Elevated Carbon Dioxide for Eight Years
… global carbon cycle. Increases in atmospheric CO2 concentrations strongly influence plant carbon uptake and because forests account for the bulk of terrestrial productivity the future role of forests in the carbon cycle is a subject of current scientific interest. This research investigates …

Boreal tree stem CO2 flux dynamics
Hiilidioksidilla (CO2) on tärkeä rooli puun toiminnassa, sillä sitä tarvitaan fotosynteesissä, käytetään biomassan kasvatukseen ja vapautetaan soluhengityksessä. Puunrungon CO2 vuo koostuu lähinnä soluhengityksestä, minkä vuoksi ilman lämpötilaa voidaan käyttää vuon ennustamiseen. Suurin osa …
