The winning bidder will have filming rights for around 300 days. In this time, park authorities plan to hold 8-12 cheetahs in a five-sq.-km fenced enclosure inside the park, where the cats will have prey like chital, sambar, wildboar and nilgai. Once they have acclimated themselves to the new area and the local prey base, the authorities will let them out into the park proper.
In Africa, cheetah density varies between one cheetah per 40 sq. km to one per 925 sq. km. Kuno National Park is 748 sq. km in size, and will soon have up to 12. This is almost full capacity, and less than what cheetahs typically need.
Recently, Y.V. Jhala, a dean at the Wildlife Institute of India who has carried out feasibility studies for the introduction project, told Hindi newspaper Dainik Bhasker that an unspecified entity would take three or four of the 12 African cheetahs to Mukundra Tiger Reserve, in Kota, Rajasthan. But the timeline is, again, unclear.
In guilds, such as the large predators, species compete over multiple resources that are both consumable and non-consumable. The niche complementary hypothesis states that competitors can overlap in resource use if there is low overlap for at least one shared resource. In Africa, cheetah, Acinonyx jubatus, compete with other large carnivores across space, time and prey and are known to be subordinate; however, rarely has the entire guild been considered when assessing resource partitioning by cheetah. Using camera-trap data from four areas sampled over 4 years, we compared spatial and temporal overlap between cheetah and other large carnivores. Moreover, we estimated short-term avoidance of sites by cheetah after another large carnivore had visited. We show that cheetah align with the niche complementary hypothesis to avoid other large carnivores. Cheetah experienced high overlap with African wild dog, Lycaon pictus, activity patterns but avoided sites that were used frequently by them. The inverse was observed for lion, Panthera leo, and spotted hyena, Crocuta crocuta, with cheetah avoiding them across time but not space. Cheetah experienced moderate overlap with leopard, Panthera pardus, across both space and time, with only possible short-term avoidance occurring. Finally, cheetah exhibited high levels of spatial and temporal overlap with preferred prey species, suggesting a novel demonstration of the trade-off between resource acquisition and predator avoidance. Our results showcase the importance of taking multiple scales and resource axes into consideration when determining species abilities to co-exist and provides tools for managers working in highly managed systems.
Panthera, a non-government organization, conducts regular camera-trap surveys within several protected areas in KwaZulu-Natal, primarily to obtain robust population estimates of leopard but also to track the relative abundance of other species. Images from these surveys were used for our analyses (Table S1). We recognize a possible bias in the data, as cameras were located to maximize the probability of capturing leopard (Miller et al. 2018). However, all carnivores regularly visited the sites and the surveys covered a full representation of the habitat types available to them. As this is a comparative study assessing point-specific spatial and temporal activity of the focal species (cheetah), as well as their competitors and prey, the data are deemed appropriate.
To identify factors affecting the increased use of a site by cheetah, we used a truncated model, including only sites that had a minimum of one cheetah capture (Swanson et al. 2016). Once again, we ran a generalized linear mixed-effect model using the Poisson distribution with cheetah abundance (all captures summed per camera-trap site) as the response variable. Lion, leopard, spotted hyena, and African wild dog abundance were used as fixed effects, as was visibility and prey RAI per size class. Camera trap site ID nested in reserve and trap effort were used as random variables.
In total, 167 camera-trap sites were surveyed for a total of 18,578 days. This yielded 214 photos of cheetah (128 independent captures at 56 sites, 34%), 1055 photos of lion (648 independent captures at 129 sites, 77%), 1547 photos of leopard (1337 independent captures at 146 sites, 87%), 2346 photos of spotted hyena (1923 independent captures at 139 sites, 83%), 659 photos of African wild dog (278 independent captures at 83 sites, 50%), 4440 photos of small-bodied prey (4102 independent captures at 161 sites, 96%), 42,226 photos of medium-bodied prey (20,758 independent captures at 167 sites, 100%), 14,037 photos of large-bodied prey (6772 independent captures at 165 sites, 99%), and 2017 photos of extra-large-bodied prey (1390 independent captures at 122 sites, 73%).

Our results demonstrate that cheetah space and time use follow the predictions of the niche-complementarity hypothesis, by avoiding other large carnivores on at least one of the non-dietary resource axes available to them, but they did not avoid any competitor on all axes (Table 3). Specifically, we show that cheetah avoided: African wild dog across space, spotted hyena and lion through time, and leopard through short-term avoidance (spatiotemporal). Moreover, we found support for cheetah aligning their habitat selection and activity patterns with that of their preferred prey and weak support for the avoidance of extra-large-bodied prey, as a way to avoid large carnivores that prefer large prey (Vanak et al. 2013). There is thus a trade-off in resource acquisition and risk avoidance in which cheetahs apparently prioritize finding suitable prey and are able to effectively reduce risky encounters with dangerous competitors without requiring constant avoidance behavior.
Cheetah showed the highest overlap in activity patterns with small- and large-bodied prey and their abundance at a camera-trap site was positively influenced by large-bodied prey. This supports our prediction that cheetah are attempting to align themselves with commonly utilized prey (Clements et al. 2014). The lack of support for medium-sized prey could have been biased by one of two things: the day-time activity of warthogs biasing that data diurnally (Hayward and Slotow 2009), and the high capture rate of this prey class at almost all sites due to the high abundance of species in this class in all reserves.
Spatially, we again found mixed support for our hypothesis that cheetah would select sites with low-to-no dominant carnivore use. Cheetah presence was negatively related to African wild dog presence. This result supports our predictions, as cheetah had high temporal overlap with African wild dog, but avoided them across space, selecting for sites that African wild dog were not using. This may reflect exploitative competition between cheetah and African wild dog, as shown to occur at least one of our study sites (Cornhill and Kerley 2020b). However, it is also possible that this was not a product of cheetah avoiding African wild dog, but African wild dog avoiding sites where all other large carnivores were found (Vanak et al. 2013; Swanson et al. 2014; Dröge et al. 2017). In addition, lion abundance was positively associated with cheetah abundance, but otherwise large carnivores had no effect of cheetah habitat use. Dröge et al. (2017) found no spatial avoidance by cheetah toward other large carnivores, indicating that cheetah are most likely to select areas based on the prospects of obtaining prey.
If cheetah focused exclusively on risk avoidance, they would be at risk of starvation, for they could not capture prey. This is similar to the trade-off (food vs risk) response of the Serengeti herbivore community, with Sinclair (1985) showing that as grazing became limiting in the dry season, grazers were more willing to accept the risk of predation, than when grazing was abundant. We showed that cheetah were willing to utilize resources that would be deemed risky (e.g., night time and closed habitat) under the landscape of fear hypotheses (Laundré et al. 2001) as the risk associated with these resources must have not been high enough to warrant outright avoidance, a result supported by Swanson et al. (2016). Rather, cheetah are driven by their need to acquire prey and thus use other mechanisms to avoid risk (the niche complementary hypothesis).
Our study is the first to evaluate cheetah resource use taking into account the entire large carnivore guild and across multiple axes. It expands on previous work (Durant 1998; Cozzi et al. 2012; Broekhuis et al. 2013; Vanak et al. 2013; Bissett et al. 2015; Swanson et al. 2016; Dröge et al. 2017), giving managers more refined tools to achieve their objectives. This is especially useful to managers struggling with the challenges of isolated populations and reliance on tourism revenue, such as at our study sites. Pressure from tourists for large carnivore sightings often leads to reserves stocking animals at higher than appropriate densities, with management actions required to ameliorate possible problems (Slotow and Hunter 2009; Clements et al. 2016). A greater understanding of how all sympatric carnivores as a guild influence cheetah behavior may contribute to improved management of the species. Our results show that even with potentially artificially high carnivore densities and with fences restricting movements, cheetahs are able to co-exist with intact large carnivore guilds given adequate prey densities.
Our study shows that cheetah uses resource partitioning to avoid the potential costs of competition, but that this also represents a trade-off with the need to acquire prey. Resource partitioning does not need to occur on all axes for all competing large carnivores, nor was the response by cheetah symmetrical across all competing large carnivores. As we assessed resource use on multiple axes, we were able to show that cheetah avoided different carnivores on different axes. These results showcase the importance of looking at the intact predator guild and their use of several resources to obtain a full understanding of how competition shapes resource use.
