                         evapotranspiration influenced by biotic and abiotic factors 
                         through analysis of diurnal variation of aerodynamic resistance 
                         (ra), stomatal resistance (rs) and decoupling factor (\Ω). 
                         This index was proposed by Jarvis and McNaughton (1986) as an 
                         indicative of the control of these resistances on the 
                         evapotranspiration of vegetation. Selection of representative data 
                         from wet and dry seasons from a primary forest in Central Amazonia 
                         and a primary forest and a pasture sites in Southwestern Amazonia 
                         had shown that: (i) ra is about 20 s.m-1 in both forests in both 
                         seasons, and ranges from 70 to 100 s.m-1 in the pasture site; (ii) 
                         rs varies both throughout the day and seasonally, with medians 
                         increasing from 40 in the morning, to 150 s.m-1 in late afternoon, 
                         in the wet season in the forests and from 50 to 160 s.m-1 in the 
                         pasture. These values increase in the dry season, with the forests 
                         rs ranging from 50 up to 500 s.m-1 and pasture rs starting from 
                         140 s.m-1 and reaching up to more than 1800 s.m-1 in the dry 
                         afternoons; (iii) \Ω ranges from 0.5 to 0.8 during the wet 
                         season, and reduces to values below 0.5 in the afternoons during 
                         the dry season, indicating that, although a strong influence of 
                         net radiation in the evaporative loss is present, to a large 
                         extent the evapotranspiration fluxes are coupled to the biotic 
                         control of stomatal closure in the vegetation, especially in the 
                         pasture and during dry periods.",
