Carbon stocks in root biomass and soil organic carbon (SOC) were analysed in tropical mountain cloud forest (TMCF) of Mexico. Additionally, the hypothesis that the concentration of roots in the forest is not homogeneous but that they are concentrated near the trunks of the trees was evaluated. Root biomass was 707.68 ± 150.41 g·m ⁻² , which stores...

El bosque tropical estacionalmente seco se localiza en México, específicamente en las costas del Golfo de México, Mar Caribe y el Pacífico, donde alberga una gran diversidad de especies animales y vegetales.
