  Engelbrecht, Eileen (University of Pretoria, 2023)

  Invasive species are considered a major biological threat to the planet, causing losses on economic and environmental fronts. Lantana camara is one of the worst invasive plant species, globally and in South Africa, with ...
• Stable isotope values of Marion Island myctophids using otoliths from fur seal faecal samples 

  Van Tonder, André (University of Pretoria, 2023)

  Lanternfish (Myctophidae) are abundant mesopelagic fishes in the Southern Ocean ecosystem and represent a large dietary component for sentinel marine predators, such as seals and seabirds. Their contribution to diets of ...
• Efficacy, host-finding ability and application methods of entomopathogenic nematodes to control pupae of Gonipterus sp. 2 (Coleoptera: Curculionidae) 

  Rakubu, Innocent Lephaswa (University of Pretoria, 2023)

  Gonipterus sp. 2 is a pest of economic importance to South Africa as it threatens the sustainability of eucalypt plantations. The adult beetles and larvae cause damage to Eucalyptus spp. through defoliation. There are ...
• Coexistence among South African carnivores : spatial and temporal partitioning and their ecological correlates 

  Smith, Kyle (University of Pretoria, 2023)

  Carnivore species coexistence is shaped by niche partitioning that developed over evolutionary time through behavioural responses and adaptations to interspecific competition and risk. Minimising lethal and sub-lethal ...
• The effects of neonicotinoids and increasing temperatures on the thermoregulation and flight ability of South African honey bees, Apis mellifera scutellata (Lepeletier) 

  Bester, Laura Catherine (University of Pretoria, 2023)

  Predicted climatic changes throughout the southern African region are likely to affect the distribution of ecological zones, significantly impact agricultural yield, and influence the timing of the flowering season. Climate ...
• Hoverflies (Diptera : Syrphidae) as pollinators of sunflowers in the Waterberg region of Limpopo province, South Africa 

  Brits, Xavier (University of Pretoria, 2023)

  Pressure is being placed on the agricultural sector to supply an ever-growing demand for food as the population continues to increase globally. This is further complicated by a continues decrease in pollinators needed for ...
• Diversity of fruit flies (Diptera: Tephritidae) from the South African highveld and lowveld : a preliminary assessment of Wolbachia infection 

  Seabi, Onkgopotse (University of Pretoria, 2022)

  Food security, as far as horticultural production is concerned, requires research into pest control methods at all stages of production. Tephritid fruit flies are among the most serious agricultural pests worldwide, owing ...
• Elucidating the molecular epidemiology of trypanosomes for evidence-based tsetse-vector control in the Shimba Hills human-wildlife-livestock interface, Kenya 

  Ebhodaghe, Faith Isikhuemen (University of Pretoria, 2022)

  Field studies that systematically evaluate the transmission dynamics, reservoir hosts, and genotype diversity of trypanosome parasites are scanty in sylvatic ecologies in sub-Saharan Africa. Such studies are important for ...
• Endocrine control of reproductive suppression in three Cryptomys hottentotus subspecies 

  Janse van Vuuren, Andries Koch (University of Pretoria, 2022-03-23)

  How social group cohesion is maintained in cooperatively breeding species has been the subject of a significant body of research. In many cooperatively breeding species, subordinate individuals are prevented from breeding ...
• Intraspecific and interspecific olfactory interactions and density of leopards Panthera pardus (Linnaeus, 1758) in Sabi Sands Game Reserve, South Africa 

  Gervais, Agathe (University of Pretoria, 2021)

  The olfactory behavioural ecology of large solitary carnivores is still poorly understood. Meanwhile, these species represent challenging cases in conservation and management. They are frequently involved in conflicts with ...
• The effects of long-term burning regimes on savanna spider assemblages 

  Reynolds, Bradley Neil (University of Pretoria, 2014-07)

  Fire is an important disturbance in many biomes throughout the world and plays a major role in savannas, where it affects the composition and structure of vegetation, which in turn structures faunal assemblages. Higher ...
• Inter-population craniometrics of adult male Subantarctic fur seals (Arctocephalus tropicalis) 

  Moshobane, Moleseng Claude (University of Pretoria, 2014-03)

  Craniometrics is a very reliable and effective tool for studying the difference in animal morphology. Previously, traditional craniometrics were conducted with the aid of calipers in two dimensional format (2D). Such ...
• Characteristics and affinities of the fynbos vegetation on Mariepskop, Limpopo Province, South Africa 

  Coetzer, Nadine (University of Pretoria, 2014-11-30)

  Prior to this in-depth phytosociological classification and biogeographical study, the only other intense floristic study focussing on all plant species done specifically on Mariepskop was the work by Van der Schijff and ...
• Assessment of the life history characteristics of Rhinolophus blasii (Mammalia, Chiroptera) in South Africa 

  Wei, Mengjing (University of Pretoria, 2021)

  This study investigated variation in activity, relative abundance, and body condition of Blasius’s horseshoe bat (Rhinolophus blasii) in relation to temperature, season, rainfall, and wind speed across seven years at the ...
• Evaporative cooling capacity and heat tolerance on Kalahari Desert birds : effects of body mass and phylogeny 

  Whitfield, Maxine (University of Pretoria, 2014-03)

  The roles of phylogeny and body size in avian heat stress physiology, and how they interact to set the upper limits to heat dissipation capacity, are largely unexplored. Determining thermal end points and maximum capacity ...
• Personality, hormonal correlates and parasite load in the eastern rock elephant shrew 

  Hoffmann, Sasha (University of Pretoria, 2014-02)

  Inter-individual variation in behaviour, or as it has now come to be known, personality, has been shown to affect many different components of fitness in animals. A concept that used to be thought of as background ‘noise’ ...
