Private Protected Areas (PPAs) often use wildlife-based ecotourism as their primary means of generating business. Achieving tourist satisfaction has become a strong driving goal in the management of many PPAs, often at the expense of biodiversity. Many extralimitral species, those which historically did not occur in an area, are stocked in PPAs with the intention of increasing ecotourism attrac...
Serial injections (i.m.) of 10 mg follicle stimulating hormone (FSFI-P) to cheetahs for 5 days followed by human chorionic gonadotropin (hCG, 500 IU) administered on both Days 6 and 7 resulted in ovarian follicle development and/or ovulation in six of seven attempts. One additional female given the same gonadotropin regimen when distinct corpora lutea (CL) were visible on the ovaries failed to ...

Animals navigate their environment using a variety of senses and strategies. This multiplicity enables them to respond to different navigational requirements resulting from habitat, scale and purpose. One of the challenges social animals face is how to reunite after periods of separation. We explore a variety of possible mechanisms used to reunite the members of a cheetah coalition dispersed wi...
The cheetah (Acinonyx jubatus) has been described as a species with low levels of genetic variation. This has been suggested to be the consequence of a demographic bottleneck 10 000-12 000 years ago (ya) and also led to the assumption that only small genetic differences exist between the described subspecies. However, analysing mitochondrial DNA and microsatellites in cheetah samples from most ...
This paper proposes an analysis of the energy efficiency a small quadruped robotic structure, designed based on MIT Mini Cheetah, controlled using central pattern generator FitzHugh–Nagumo neuron. The robot’s performance evaluated structurally complex terrain in dynamic simulation environment is compared with other structures wheels and hybrid architectures. cost involved carrying out assigned ...
For more than two decades, the cheetah (Acinonyx jubatus) has been considered a paradigm of disease vulnerability associated with low genetic diversity, particularly at the immune genes of the major histocompatibility complex (MHC). Cheetahs have been used as a classic example in numerous conservation genetics textbooks as well as in many related scientific publications. However, earlier studie...
