    Understorey bird species diversity and abundance in three forest types of Semuliki National Park, Uganda

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Sande, E. 2000. Understorey bird species diversity and abundance in three forest types of Semuliki National Park, Uganda. Ostrich 71 (1 & 2): 64–68.
  2. Avian guild assemblages in forest fragments around Budongo Forest Reserve, western Uganda

    Avian guild assemblages in forest fragments around Budongo Forest Reserve, western Uganda

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Remnant forest fragments provide an opportunity for conservation in fragmented landscapes but some patches are more useful than others. Forest fragments around Budongo Forest Reserve, an Important Bird Area in western Uganda, were surveyed to explore the effects of different...
  3. Characterisation of regular graphs as loop graphs

    Characterisation of regular graphs as loop graphs

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    There have been various generalisations of Cayley graphs, prototypes of transitive graphs. The most generalised is the description of graphs on general groupoids. What has clearly emerged in this exercise is that the philosophy of constructing graphs on groupoids offers...
  4. COMPLEMENTED RANGE SPACES

    COMPLEMENTED RANGE SPACES

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Most of the well known perturbation results hold for linear operators whose nullity or defect is finite, which implies the existence of topological complements to the null and range spaces respectively. This paper investigates properties associated with the stability of...
  5. ON Ω–KRMULL RINGS

    ON Ω–KRMULL RINGS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper we give a survey of a few selected results on non-commutative K1-ull rings in the sense of L. Le Bruyn, P. Wauters and the author. These rings are called Ω-Krull rings.
  6. THE INFLUENCE OF RAINFALL ON BLACK EAGLE BREEDING OVER 31 YEARS IN THE MATOBO HILLS, ZIMBABWE

    THE INFLUENCE OF RAINFALL ON BLACK EAGLE BREEDING OVER 31 YEARS IN THE MATOBO HILLS, ZIMBABWE

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Gargett, V., Gargett, E. & Damania, D. 1995. The influence of rainfall on Black Eagle breeding over 31 years in the Matobo Hills, Zimbabwe. Ostrich 66: 114–121.

  8. Representing vertex-transitive graphs on groupoids

    Representing vertex-transitive graphs on groupoids

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Vertex-transitive graphs are one of the most favoured class of graphs in modelling scientific phenomena if symmetry is at issue. An understanding of these graphs should, therefore, be an obvious undertaking. Here, we present a characterisation of vertex-transitive graphs as...
  9. ASPECTS OF BOUNDED PERTURBATION THEORY

    ASPECTS OF BOUNDED PERTURBATION THEORY

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    This paper is concerned with the stability of certain properties of linear operators in locally convex topological vector spaces under perturbations by operators which are small in some sense. Section 3 deals with the very useful concept of Banach balls...
