Tema(s): Recursos en línea: Resumen: We present results of a study in an intensively impacted and highly fragmented landscape in which we apply field-measured carbon (C)density values to land-use/ land-cover (LU/LC)statistics to estimate the flux of C between terrestrial ecosystems and the atmosphere from the 1970s and 1990s. Carbon densities were assigned to common LU/LC classes on vegetation maps produced by Mexican governmental organizations and, by differencing areas and C pools, net C flux was calculated from the central highlands of Chiapas, Mexico, during a 16-year period. The total area of closed forests was reduced by half while degraded and fragmented forests expanded 56
