An optimal control model is constructed where the cutting of old-growth forest generates jobs and adds to the stock of land devoted to "newgrowth," rotational forestry. Welfare is determined by the number of jobs in the forest economy and the stock of old-growth forest, which provides "nontimber" benefits.

Abstract Old-growth has been used and understood by foresters and ecologists for a long time. The term implies that the organism must be old, becoming overmature, senescent, slow growing, and declining in vigor. But the precise characteristics and attributes of the term are not identified.

EGF: new tricks for an old growth factor
Current Opinion in Cell Biology, 1993During the past year, the biology of epidermal growth factor (EGF) has been investigated in lower organisms (Caenorhabditis elegans, Drosophila and bacteria). These experiments have produced some surprising results: the identification of defects produced by mutation of EGF-like genes; the role of EGF receptors in bacterial invasion; and the role of EGF-

Distance decay in an old‐growth neotropical forest
Journal of Vegetation Science, 2005Abstract. Questions: Does distance decay exist in an old‐growth neotropical forest? Is this distance decay stronger than expected due to environmental heterogeneity alone? At what spatial scales are distance decay manifested?Location: La Selva Biological Station, Costa Rica, Central America.Methods: An index of distance decay is applied appropriate
