  1. To run or hide?: escape behaviour in a cryptic African snake

    To run or hide?: escape behaviour in a cryptic African snake

    Item type: Journal Article • Journal: African Zoology
    Optimal escape theory predicts that escape behaviour of an organism is best understood in terms of costs and benefits of escaping relative to risk of predation. However, risk of predation facing an organism is dependent on various biotic and abiotic...
  2. Assessing the threat of avian predation on a small viperid snake

    Assessing the threat of avian predation on a small viperid snake

    Item type: Journal Article • Journal: African Zoology
    Predators are important because they influence survival rates, population density and behaviour of prey species. However, assessing the predation pressure facing a particular species is difficult when that species faces a suite of predators. We aimed to characterize the suite...

  5. ON A THEOREM OF A.A. LYAPUNOV

    ON A THEOREM OF A.A. LYAPUNOV

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this note we obtain some extensions and an approximation of the Lyapunov convexity theorem by means of the bilinear integration of a set-valued function. The integration is performed successively with respect to a non-atomic, a direct sum and a...
  6. THE INTERIORITY OF A MULTIFUNCTION

    THE INTERIORITY OF A MULTIFUNCTION

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    We study the set of points of a topological space X at which a multifunction F: X → Y is interior. This paper also deals with the valuation of the Borel class of this set. The necessary examples and counterexamples...
