Producción y descomposición de hojarasca en diferentes condiciones sucesionales del bosque de pino-encino en Chiapas, México

Litter production was evaluated in successional pine-oak forests in two localities in Chiapas; simultaneously we assessed the leaf-litter decomposition of seven tree species ( Alnus acuminata subsp. arguta, Chiranthodendron pentadactylon, Clethra suaveolens, Liquidambar styracifl ua, Quercus crassifolia, Quercus sapotifolia and Pinus oocarpa ). After 1-year, the highest litter production was recorded in pine-oak-forests (7.59±0.29 Mg·ha-1·year-1), followed by the oak forests (6.58±0.27 Mg·ha-1·year-1), pineoak-Liquidambar forests (5.33±0.18 Mg·ha-1·year-1), pine forest (5.18±0.19 Mg·ha-1·year-1), and the lowest annual litter production occurred in the plots under forest restoration (2.43±0.13 Mg·ha-1·year-1). After 10-mo, the highest rate of leaf-litter decomposition occurred in Alnus acuminata (61-67%) regardless of the forest conditions and in the rest of the species, litter decomposition ranged from 34-52%, but not signifi cant differences between forest conditions were observed.
