  • Environmental variability and system heterogeneity in terrestrial biogeochemical models

    Creator:
    Sierra, Carlos Alberto
    Abstract:
    Ecosystems are highly heterogeneous systems subjected to important levels of environmental variability; however, it is common in terrestrial biogeochemical models to assume homogeneous properties of the elements of the system or constant environmental conditions. For some processes, heterogeneity in these models is treated very simplistically, but there is not much...

  • Spatial and temporal variability of carbon dynamics in a tropical forest of Colombia

    Creator:
    Sierra, Carlos Alberto
    Abstract:
    Despite the importance of tropical forest ecosystems in the global carbon cycle, there have been few studies of carbon dynamics in this biome. The magnitude of carbon stocks in the tropics and their changes over time are poorly known since ground-based observations are lacking. In this study, total carbon stocks...
