  • Modeling light competition in the forests of western Oregon

    Creator:
    Hanus, Mark L.
    Abstract:
    A plant's immediate neighborhood reflects its realized level of competitive stress, since competition and natural selection act at the individual level. In stands with continuous canopies competition for light is the dominant spatial interaction. Over 100 spatially explicit indices have been used to characterize the local competitive environment in models...

  • Disaggregative and individual-tree growth models in theory and application

    Creator:
    Ritchie, Martin W.
    Abstract:
    Disaggregative and individual-tree/distance-independent modeling methods are compared and contrasted. Differences between the two are related to differences in functional and apparent resolution and may be illustrated using aggregation theory. When considering models of different levels of resolution describing a given phenomenon, invariance with respect to the aggregation implied (symmetry) may...
