Biogeography of Angolan rodents: The first glimpse based on phylogenetic evidence
- Environmental Science, BiologyDiversity and Distributions
Assessment of phylogenetic diversity and biogeographical affinities of the rodent fauna from one of the most neglected areas in Africa shows clear trends in phylogenetic Diversity and Biogeographical Affinities.
Quaternary fossil fauna from the Luangwa Valley, Zambia

This paper describes a large collection of Quaternary fossil fauna from the Luangwa Rift Valley, Zambia. Stone Age artefacts have been recovered from stratified fluvial contexts, but no in situ…
TICKS AND TICK-BORNE PATHOGENS FROM WILDLIFE IN THE FREE STATE PROVINCE, SOUTH AFRICA
- Biology, MedicineJournal of wildlife diseases
Eight ixodid tick species, associated with 59 free-ranging mammals belonging to 10 species, were collected at five different localities in the Free State Province, South Africa andGene sequences recovered in this study were 98–100% homologous with GenBank sequences for Anaplasma bovis, theileria separata, and Theileria sp.
Ecological and life-history correlates of enamel growth in ruminants (Artiodactyla)
- Geography, Environmental Science
The application in two fossil species provides evidence that EFF angle is a reliable proxy of the life history of extinct mammals, and suggests that the two mechanisms of enamel growth might be subject to different selective forces.

Here we present the recently discovered desert kites of South Africa in terms of landscape-based data derived from LiDAR scanning that enable us to compare the morphometric and topographic…
The evolution of body size, horn shape and social behaviour in crown Antilopini - an ancestral character state analysis
Using a species level phylogeny of this group, the results for the reconstruction of ancestral social organisation of the dwarf species are inconclusive, but the small body size and short horns of Ourebia, Raphicerus, Dorcatragus, and Madoqua are most likely derived traits.
A Fossil History of Southern African Land Mammals

There is an ever-growing wealth of mammalian fossil material being collected from palaeontological and archaeological sites in southern Africa. This reference provides comprehensive information on…
Sexual dimorphism across 3 stages of development in polygynous Artiodactyls is not affected by maternal care
- BiologyCurrent zoology
On the whole, postnatal maternal care seems to have no or even an inverse effect on the evolution of dimorphism, which is apparently not consistent with the assumption of greater maternal investment in male than in female offspring among polygynous mammals.

Pollen analysis is frequently used to build climate and environmental histories. A distinct Holocene pollen series exists for Chaco Canyon, New Mexico. This study reports linear modeling and…
Antelope adaptations to counteract overheating and water deficit in arid environments
- Environmental Science, BiologyJournal of Arid Land
This review provides a better understanding of the main behavioral mechanisms of antelope adaptations to arid environments and allows for the identification of the key factors for successful conservation of antelopes in their natural habitats.

Population genetics of the springbok Antidorcas marsupialis - a preliminary study
Biochemical-genetic variation was studied in springbok Antidorcas m. marsupialis (Zimmermann, 1780) from a large (N>2000) "wild" population (n=24) and a small (30>N>20) isolated farm population…
Observations on the migration and habits of the Antelopes of the Kalahari Gemsbok Park - Part II
- Environmental Science, Geology
To follow up the observations made in the Kalahari Gemsbok Park in December, 1957, a second trip was made in June, 1958 on which the present report is based. It is intended mainly as a progress…
Observations on Social Organization of Springbok, Antidorcas Marsupialis, in the Bontebok National Park, Swellendam
AbstractThe study area of 2 786 ha contained over 200 springbok. The data were gathered during 78 separate day visits over four years. The most important social groups were (1) nursery herds of…
Preferential utilization of pans by springbok (Antidorcas marsupialis)
- Environmental Science
Forage utilization by springbok in pans and surrounding habitats was compared at one karroid shrubland site and two desert grassland sites and was found to be greater in pans than on adjacent plains…

Nematodirus spathiger had the widest host spectrum and with the exception of black wildebeest, was collected from all the host species examined.
Hygroscopic Food: a Source of Water for Desert Antelopes?
- Biology, MedicineNature
I collected plants which were eaten by antelopes during a drought, determined the rate at which the dry leaves gain water at temperatures and humidities measured during the drought, and calculated the amount of water available to the antelope if they feed at night.
Observations on the Behaviour and Feeding Habits of the Springbok, Antidorcas Marsupialis
AbstractThe stance and attitudes of the springbok are found to be similar to those of other gazelles. Gaits used are a rack-like walk (passgang), a trot and a gallop; display trot, the stott and the…
The vegetation of the S.A. Lombard Nature Reserve and its utilisation by certain antelope
- Environmental Science
All the antelope on this reserve except gemsbok, feed by nibbling the plants here and there, and it was a tedious task to trace the exact feeding spot.
SPATIAL UTILISATION OF AN ENCLOSED AREA OF THE KAROO BY SPRINGBOKANTIDORCAS MARSUPIALISAND MERINO SHEEPOVIS ARIESDURING DROUGHT
Observed inter-specific differences suggest that a combination of springbok and Merino sheep in a 350 ha paddock on a game ranch in the Karoo would lead to a better utilisation of the vegetation.
Some observations on social organisation and behaviour of springbok in the Jack Scott Nature Reserve
Aspects of social organisation and behaviour of springbok were observed in a small population in the Jack Scott Nature Reserve, Transvaal, and observations of intolerant behaviour on the part of such males towards other male springboks suggested territoriality.
