Nectar preferences of specialist and occasional avian nectarivores, and their role in the evolution of floral traits.
(2009)Our understanding of bird pollination systems has changed dramatically in the last few years. A long-standing paradigm was that hummingbirds and passerine birds select for different nectar properties in flowers ... -
On the behavioural ecology and vocal communication of the brown-headed parrot (Poicephalus cryptoxanthus)
(2002)The Brown-headed Parrot (Poicephalus cryptoxanthus) is a poorly known species inhabiting open woodland in south-eastern Africa. This study elucidates critical aspects of the species ecology and although each of ... -
An outline of the ecology and behaviour of the red lechwe (Kobus leche leche Gray, 1850)
(1979)In a number of publications serious concern has been expressed about 'the status of lechwe in the Kwando/Linyanti/Chobe system. Concern has also been expressed about the effects of possible water extraction from the ... -
Patterns of animal endemism in the Maputaland-Pondoland-Albany biodiversity hotspot.
(2013)The Maputaland-Pondoland-Albany (MPA) hotspot, as is the case of all such global biodiversity hotspots, has primarily been recognised based on its high floristic endemism and delimited intuitively. Boundaries of global ... -
Patterns, mechanisms and evolution of avian facultative hypothermic responses : a southern African perspective.
(2001)Recent evidence suggests that avian facultative hypothermic responses are more common than previously thought. Traditionally, several categories of avian hypothermic responses have been recognized, and are frequently ... -
Phylogeny of the Ammobatini and revision of the Afrotropical genera (Hymenoptera : Anthophoridae : Nomadinae)
(1994)The phylogeny of the Ammobatini was studied, with regard to the principles of cladistics using parsimony, and the classification is revised. It is concluded that the tribe forms a monophyletic group that comprises six ... -
Plant molluscicides for snail control in the South African context.
(1994)Despite more than half a century of international research on schistosomiasis control, this disease remains a public health concern in many Third World countries. Four to five percent of the world's population is estimated ... -
The population dynamics of impala (Aepyceros melampus Lichtenstein) in Mkuzi Game Reserve.
(1979)The need to understand the dynamics of the impala population in Mkuzi Game Reserve arose during the early 1960's when it became clear that various factors were contributing to an overpopulation of the species in the ... -
Population genetics of the striped-mouse, Rhabdomys Pumilio (Sparrman, 1784)
(1999)The striped-mouse, Rhabdomys pumilio, is widely distributed throughout southern Africa within a variety of habitats and rainfall regimes. It is found at sea level in the Eastern and Western Cape regions and at altitudes ... -
Reproduction and population ecology of the blue wildebeest Connochaetes taurinus taurinus in Zululand.
(1977)A two-year study was made of the blue wildebeest Connochaetes taurinus taurinus in Zululand, Natal. Aspects investigated included age determination methods, growth and condition, reproductive physiology, habitat ... -
Reproductive behaviour and habitat use in the Blue-Eyed Black Lemur (Eulemur flavifrons, Gray, 1867) at the Sahamalaza-Iles Radama National Park, Madagascar.
(2009)The critically endangered blue-eyed black lemur (Eulemur flavifrons) is one the leaststudied day active lemurs because of the recent rediscovery and limited distribution. This thesis examined the habitat use, reproductive ... -
Resistance in maize to the maize stalk borer, Busseola fusca (Fuller) (Lepidoptera: Noctuidae)
(1989)An in depth review is given of Host Plant Resistance research on borers in general, and on B. fusca in particular. The general biology and economic importance of B. fusca are also discussed. Several aspects of the ... -
Resource partitioning in a viverrid assemblage.
(1988)Viverrids are small carnivores that achieve high species richness throughout their range. This study investigated the ecology and resource partitioning of five members of this family (Genetta tigrina, Herpestes ichneumon, ... -
A review of the old world genera of Lauxaniidae (Diptera)
(1971)This paper presents in key form a review of the Old World genera of Lauxaniidae. Thirteen new genera are erected, three genera are placed in synonymy, four subgenera are given generic status, and one genus is transferred ... -
A revision of the genus Ancilla Lamarck, 1799 (Mollusca : Olividae : Ancillinae)
(1982)The genus Ancilla Lamarck, 1799, contains 34 valid species and subspecies; 41 names previously applied to the group are reduced to 23, and 11 new species described (Kilburn, 1977, 1980, 1981). A provisional subgeneric ... -
