As the dry season progresses across southern Africa, the availability and quality of food declines for large herbivores. Female white rhinos compensate for these declines by expanding and/or shifting their home ranges. ...

The changes in plant quality and availability in space and time present a substantial problem to mammalian herbivores. As a result, these herbivores need to alter their foraging behaviour to maximize their energy gain at ...

Evolutionary transitions from insect to wind pollination are thought to have occurred many times during the angiosperm radiation. This transition is commonly associated with a suite of distinctive floral traits such as ...

In South Africa, oribi (Ourebia ourebi) antelope are listed as vulnerable. The lack of understanding of their population dynamics makes it difficult for oribi conservation. To address these gaps, I used the Oribi Working ...

Pollinators are believed to have played a key role in the radiation of flowering plants. The Grant-Stebbins model of pollinator-mediated speciation, in which evolutionary shifts between pollinators result in phenotypic ...

Water has become a scarce commodity in Sub-Saharan Africa and in drought prone South Africa. Due to the extensive utilization of water resources in South Africa, management and monitoring of our rivers and estuaries is ...

The excessive use of water resources and climate change stressors is impacting the quality and quantity of surface aquatic ecosystems in South Africa, a semi-arid country. Although South Africa is considered to be a ...

Despite their popularity, parrots are the world’s most threatened birds. Lovebirds (Agapornis) are very popular pet and aviary birds and as ecologically specialised species in the wild, they are also among the most threatened ...

The unprecedented changes in the environmental and ecological processes of the biosphere have led some to believe that we have transitioned into a new geological era from the Holocene. This current era is known as the ...

According to the mesopredator release hypothesis, when apex predators disappear from an ecosystem, the number of mesopredators increase and thus predation of prey species increases. Since the extermination of large predators ...
