ABSTRACT Models that simulate the process of stomatal conductance (gs) for a given set of environmental conditions are important, as this process is the main mechanism that controls the gas exchange of terrestrial plants absorbing atmospheric CO2 in

Publikováno v: Sustentabilidade em Debate, Vol 11, Iss 2 (2020)

Cenários de mudança de uso e cobertura da terra na Amazônia são necessários para subsidiar decisões que podem evitar a emissão de milhões de toneladas de CO2 para a atmosfera. Portanto, é importante avaliar modelos que visam a geração de c
