Carbon dioxide balance in early-successional forests after forest fires in interior Alaska
Masahito UEYAMA, Hiroki IWATA, Hirohiko NAGANO, Narumi TAHARA, Chie IWAMA, Yoshinobu HARAZONO

Fire is the major disturbance in North American boreal forests, and is thought to be the most important process that determines the carbon balance in North American boreal forests. This study conducted four years of tower flux measurements in a burned ecosystem from one to four years after a fire, and nine years of measurements in …

Variations in fraction of absorbed photosynthetically active radiation and comparisons with MODIS data in burned black spruce forests of interior Alaska
Iwata, H., Ueyama, M., Iwama, C. and Harazono, Y.

Absorption of photosynthetically active radiation (PAR) by vegetation was observed in two burned black spruce forests, one and seven years after wildfire, in interior Alaska along with several vegetation properties. This study considered PAR absorption by mosses by examining the relationship between PAR transmittance and fractional …

Quick recovery of carbon dioxide exchanges in a burned black spruce forest in interior Alaska
Iwata, H., Ueyama, M., Harazono, Y., Tsuyuzaki, S., Kondo, M., Uchida, M.

Observations of carbon dioxide (CO2) flux with the eddy covariance technique were conducted at a burned boreal forest site five years after a wildfire and at a mature forest site in Interior Alaska to investigate the effects of wildfire on CO2 exchange in a boreal forest. Both gross primary productivity and ecosystem respiration …
