    Managing human disturbance: factors influencing flight-initiation distance of birds in a West African nature reserve

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Escape behaviour in response to perceived predators can be employed as a guide when designating protected areas around sensitive bird species to minimise the impact of human disturbance. A key measure of escape response is flight-initiation distance (FID), the distance...

    Item type: Journal Article • Journal: South African Forestry Journal
    Clonal identities in a tree breeding and clonal development programme in Portugal consisted of two letters followed by a number of up to three digits. In Eucalpytus globulus clones the letters encoded pedigree information (and the year of induction into...

    A distance meter for large swimming marine animals

    Item type: Journal Article • Journal: South African Journal of Marine Science
    An electronic distance meter for marine animals is described. The device was tested on jackass penguins Spheniscus demersus, but could easily be modified for use on a variety of animals.

    (Φ, <em>M</em>)–extensions of near-rings

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper, we define and study a generalization of matrix, polynomial, and group near-rings. New results on ideal essentiality and lying over are obtained.
  6. Approach structures and measures of connectedness

    Approach structures and measures of connectedness

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Measures of connectedness versus disconnectedness are introduced in anarbitrary topological construct as fixed points of a Galois connection. This places measures of connectedness found in the literature in a general categorical frame-work.
  7. Morphology and affiliation of the centric diatom <em>Anaulus birostratus</em> (Grunow) Grunow from South Africa

    Morphology and affiliation of the centric diatom <em>Anaulus birostratus</em> (Grunow) Grunow from South Africa

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The morphology of a rectangular, pillow-shaped, centric diatom from the surf zone in False Bay and Algoa Bay was studied with the light microscope and by scanning and transmission electron microscopy. Acid-cleaned (i.e. free of organic material), and critical-point- and...
