(University of Pretoria, 2024-04)Gonipterus sp. n. 2 (Coleoptera: Curculionidae), native to Australia, was reported in South Africa in 1916 and has become a serious pest in Eucalyptus plantations. The adults and larvae feed on young and tender leaves of ...
-
(University of Pretoria, 2023)African savanna elephants, Loxodonta africana, occur across most of Africa. Elephants are water-dependent species, and will travel to great lengths to visit desired water sources. Whether these water sources are supplemented ...
-
(University of Pretoria, 2024-03-28)The oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), is an invasive species that has rapidly spread across the African continent, endangering the security of agricultural industries. Integrated pest ...
-
(University of Pretoria, 2023)Heat-related wildlife mass mortalities are increasingly reported as extreme heat events become more common globally. Existing research on the proximal causes of these mortalities (e.g. whether animals die of hyperthermia ...
-
(University of Pretoria, 2024-03-05)Historically, South Africa has only recorded two outbreaks of encephalomyocarditis (EMC); the first in pigs in KwaZulu-Natal in 1979 and the second in free-ranging African elephants (Loxodonta africana) in the Kruger ...
-
(University of Pretoria, 2024-01-15)Sirex noctilio (Hymenoptera: Siricidae) is an invasive pest in South African pine plantations. Current pest management strategies for S. noctilio, such as silvicultural practices or biological control, are not always ...
-
(University of Pretoria, 2023-11-30)As air temperatures (Tair) increase, birds may face increasingly severe trade-offs between heat dissipation and other important behaviours (i.e. foraging and provisioning offspring), the cumulative fitness costs of which ...
-
Genetic diversity in captive and free-ranging black-footed cats (Felis nigripes) from South Africa (University of Pretoria, 2024-02-27)The black-footed cat is a small and solitary felid species that is endemic to the arid to semi-arid subregions of southern Africa but mainly occurs in South Africa. The species is currently listed in the “vulnerable” ...
-
(University of Pretoria, 2024-02-26)Postnatal growth studies give a better understanding of age related characteristics that form an essential part of mammalian research concerned with population demographics, species management and conservation, and disease ...
-
(University of Pretoria, 2023-12)Rest forms a crucial part of mammalian activity budgets and health. Yet, little research has been done on resting behaviour and the drivers behind resting behaviour. It has been suggested that predation risk, in particular, ...

-
(University of Pretoria, 2023-10-18)South African southern right whales (Eubalaena australis, right whales) migrate between their low latitude calving grounds and their high latitude feeding grounds every year. In addition to these high latitude feeding ...
-
(University of Pretoria, 2023)Worldwide, most research regarding the direct impacts of more frequent heat waves on birds has focused on arid-zone species due to their vulnerability to rising air temperatures (Tair). In contrast, mesic lowlands have ...
-
(University of Pretoria, 2022-12-14)Heterothermy is an energy saving physiological mechanism that allows small endothermic homeotherms to overcome conditions of reduced energy availability. Seasonal variations in environmental temperature and food availability ...
-
(University of Pretoria, 2023)The naked mole-rat (Heterocephalus glaber) is a subterranean mammal which occurs in colonies of up to 60 individuals. The animals have a distinct dominance hierarchy with breeders at the top specifically dominant breeding ...
-
(University of Pretoria, 2023-09-29)Dung beetles are ecosystem engineers that provide a plethora of ecosystem services such as nutrient cycling, waste removal and parasite suppression. Recent evidence suggests that dung beetles rely on symbiotic gut bacteria, ...
-
(University of Pretoria, 2023)Subterranean mammals inhabit and thrive over a range of environmental aridities and, as such, are exposed to varying water availability, which they obtain through their diet of underground geophyte storage organs. Evolutionary ...
-
(University of Pretoria, 2023-10)Lead poisoning poses a significant global risk to wildlife and is widespread among scavenging raptors. The plight of African vultures calls for urgent evaluation of environmental toxins that may threaten their future ...
-
(University of Pretoria, 2023)With an increased demand for alternative, inexpensive and sustainable protein sources, there is an increasing interest in edible insects around the world. Tenebrio molitor, the yellow mealworm a species of darkling beetle, ...
-
(University of Pretoria, 2023)The rate of human-induced disturbance over the last century constitutes a major threat to wildlife species’ distribution, behaviour, physiological function, and overall fitness as populations struggle to respond to rapid ...
