  1. Variable community responses to herbivory in fire-altered landscapes of northern Patagonia, Argentina

    Variable community responses to herbivory in fire-altered landscapes of northern Patagonia, Argentina

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Landscapes in northern Patagonia have undergone dramatic changes in fire regimes over the last century. Superimposed on this changing vegetation mosaic are impacts from introduced herbivores. In this paper we identify synergistic interactions developing into positive fire-herbivory feedbacks that maximise...
  2. On-board computing in forest machinery as a tool to improve skidding operations in South African softwood sawtimber operations

    On-board computing in forest machinery as a tool to improve skidding operations in South African softwood sawtimber operations

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    On-board computing (OBC) systems in South African timber-harvesting operations are currently limited because of the lack of local expertise and experience. In this study three trials were conducted, monitoring three skidder extraction operations at three sites in South African softwood...
  3. A model to predict productivity of different chipping operations

    A model to predict productivity of different chipping operations

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The chipping operation is an important component of harvesting systems producing biomass and pulp chips. This paper aimed to develop a valid model to predict the productivity of chipping as part of these operations. Over a number of years more...
  4. The Self-Justifying Desire for Happiness

    The Self-Justifying Desire for Happiness

    Item type: Journal Article • Journal: South African Journal of Philosophy
    In Happiness, Tabensky equates the notion of happiness to Aristotelian eudaimonia. I shall claim that doing so amounts to equating two concepts that moderns cannot conceptually equate, namely, the good for a person and the good person or good life...
  5. Happiness and well-being: shifting the focus of the current debate

    Happiness and well-being: shifting the focus of the current debate

    Item type: Journal Article • Journal: South African Journal of Philosophy
    The point of departure of this paper is the recently emphasised distinction between psychological theories of happiness, on the one hand, and normative theories of well-being, on the other. With this distinction in mind, I examine three possible kinds of...
  6. Integrated harvesting for conventional log and energy wood assortments: a case study in a pine plantation in Western Australia

    Integrated harvesting for conventional log and energy wood assortments: a case study in a pine plantation in Western Australia

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Biomass or energy wood harvesting can be integrated with conventional log harvesting (saw log or pulpwood production) to allow more cost-effective energy wood supply. The efficiency of an integrated energy wood harvesting system was evaluated and compared with conventional log...
  7. Preliminary trials of the BioBaler working in Brazilian eucalypt plantations

    Preliminary trials of the BioBaler working in Brazilian eucalypt plantations

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The increasing demand for renewable energy feedstock has raised interest in growing eucalypts for fuel wood production, which is achieved by establishing very dense plantations cut every 18–24 months. The high moisture content of fresh Eucalyptus may handicap cut-and-chip operations,...
