Measurement of CO2 flux above a tropical rain forest at Pasoh in Peninsular Malaysia

Effect of inter-annual climate variability on evapotranspiration and canopy CO2exchange of a tropical rainforest in Peninsular Malaysia

“…Although relatively few studies have applied eddy covariance (EC) flux measurement in tropical rainforests compared with other vegetation types Baldocchi et al 2001;Yasuda et al 2003), recent studies have observed 1-3 years of flux of either evapotranspiration or CO 2 exchange at several sites in Amazonian (Malhi et al 1998(Malhi et al , 2002Araújo et al 2002;Saleska et al 2003;da Rocha et al 2004;Goulden et al 2004;Kruijt et al 2004;Miller et al 2004) and Southeast Asian (Kumagai et al 2005(Kumagai et al , 2006Takanashi et al 2005;Hirano et al 2007;Kosugi et al 2008;Takanashi et al 2010) tropical rainforests.…”

Annual variation of carbon flux and impact factors in the tropical seasonal rain forest of xishuangbanna, SW China

“…Long-term experiments in Amazonian tropical forests confirm that the forests are a sink for atmospheric C [18] . A short-term study in a Malaysian tropical rain forest drew similar conclusions; the forest under study appeared to be a net C sink at least during the measurement period [19] . However, Saleska et al measured net ecosystem exchange of carbon dioxide for 3 years in two old-growth Amazonian forests in Brazil and found that carbon was lost in the wet season and gained in the dry season [13] .…”

“…A small perturbation in this biome could have a significant effect on the global carbon cycle and climate change; thus, determining whether tropical rain forests function as a sink or source of carbon to the atmosphere is an important problem. Houghton et al and Saleska et al believed that tropical forests are significant atmospheric carbon sources [12,13] ; however, some studies found that tropical forests are carbon sinks [11,[14][15][16][17][18][19][20][21] . So it is important to determine whether the tropical forest functions as C sink or source, which could provide vital insight into the future role of tropical forests in the global C cycle and climate change [22] .…”

Throughfall at an Abandoned Skid Trail in a Tropical Rain Forest in Peninsular Malaysia

“…However, the mean Th/Rg ratio was relatively larger than the Th/Rg ratio for the much younger secondary forest in Panama. It was reported that wind speed is generally low in tropical rain forests (Tani et al 2003, Yasuda et al 2003. Hence, we did not discuss whether wind speed and direction had an effect on throughfall in this study.…”
