Acoustic signalling in bladder grasshoppers (orthoptera: pneumoridae)
Lagaa, Sasya (University of the Western Cape, 2022)Sound plays a vital communicative role in many Orthopteran insect species. Acoustic signals are often used during courtship behaviour and mate location. The Pneumoridae, commonly referred to as bladder grasshoppers, are ... -
An acoustic, genetic and morphological review of the genus Bullacris (Orthoptera; Pneumoridae)
Gordon, Mikhaila Leigh (University of the Western Cape, 2017)Bladder grasshoppers (Orthoptera: Pneumoridae) are nocturnal African herbivores that are endemic to the coastal regions of southern Africa. They rely heavily on sound communication for mate location and have a unique body ... -
The behaviour and feeding ecology of extralimital giraffe within Albany Thicket vegetation in the Little Karoo, South Africa
Paulse, Jamie (University of the Western Cape, 2018)Due to their popularity for tourism, giraffes are being introduced into Thicket areas within the Little Karoo region of the Western Cape. However, information regarding the activity budgets and diet selection of these ... -
Blood cell histology of Homopus areolatus: effects of season and cohort
Sparks, Sharna (University of the Western Cape, 2015)Homopus areolatus is an endemic terrestrial tortoise that resides in a Mediterranean type of climate, which is characterised by winter rainfall and mild winter temperatures. Within ectotherms, such as H. areolatus, ... -
Ecology and diet of the caracal (Caracal caracal) on lethal and non-lethal control farms in the Karoo
Jooste, Erin Cecilia (University of the Western Cape, 2020)Human-wildlife conflict is an ongoing issue worldwide. Within South Africa, human-carnivore conflict (HCC) as a result of carnivore depredation on small-livestock causes large-scale losses, and promotes the use of predator ... -

Genetic and morphological comparisons within the orthopteran family Pneumoridae
Laubscher, Maxine (University of the Western Cape, 2019)Bladder grasshoppers belong to the order Orthoptera, ancient family Pneumoridae and Superfamily Pneumoroidea. This small group of grasshoppers are sound producing, nocturnal, herbivorous grasshoppers endemic to the coastal ... -
Intra- and inter-population variation in the bladder grasshopper Bullacris unicolor
Sathyan, Rekha (University of the Western Cape, 2014)Although the processes that promote biodiversity and speciation remain poorly understood, ecological factors are thought to be one of the causal agents responsible for promoting variation. Bladder grasshoppers (Orthoptera; ... -
The invasive guttural toad, Amietophrynus gutturalis
Telford, Nicolas S. (University of the Western Cape, 2015)The guttural toad, Amietophrynus gutturalis, Power 1927, is a common toad with a broad geographic range through much of temperate, sub-tropical and tropical southern and central Africa. Introduced to the islands of Mauritius ... -
Tonic immobility in two species of Southern African catsharks
Sebastian, Lemόne Margeaux (University of Western Cape, 2020)Tonic immobility (TI) can be defined as an unlearned behavioural response described by a physical state of immobility. This behaviour can last from a few seconds up to several hours. Tonic immobility in sharks has not been ...
