4. The End of the Mara’s Famous Five Musketeers: While single males can easily survive by themselves, male cheetahs tend to do better when in a coalition.

Abstract

The article focuses on photographs of an incredible coalition of five male cheetahs who have gone by various names including Tano Bora, the Famous Five, and the Five Musketeers. Topics icnlude the Five Musketeers were formidable but, like with many partnerships, it did not come without its dramas, and the group from when they first formed in December 2016, the Mara Predator Conservation Programme (MPCP) has been able to document the incredible rise and fall of this famous coalition.

Abstract

Resource availability is a key component in animal ecology, yet the manner in which carnivore populations respond to spatial and temporal fluctuations of resources remains unclear. We take a population‐level approach to determine how resource pulses, in this case a temporary hyper‐abundance of prey, influence the densities and space‐use of cheetahs Acinonyx jubatus. The Maasai Mara in Kenya experiences an annual migration of > 1.4 million wildebeest Connochaetes taurinus and large numbers of zebras Equus quagga and Thomson's gazelle Eudorcas thomsonii thereby providing a natural experiment to examine the influence of resource pulses on carnivore movement and densities. To draw inferences on fluctuating cheetah densities and space‐use, we collected unstructured search‐encounter data during eight sampling sessions, four during and four out of the migration, and analysed these using Bayesian spatially‐explicit capture–recapture (SECR) models with sex‐specific detection function parameters. Both densities and space‐use fluctuated seasonally but this varied according to sex. Local cheetah densities increased in areas and during times when prey abundance was highest but this was more pronounced for females than males. In terms of space‐use, movements were larger during the migration than out of the migration but this was more pronounced for males than females. These results suggest that males are influenced more by resource distribution whereas females by resource abundance. Overall densities did vary but there was no clear pattern in relation to resource pulses. Understanding the behavioural drivers of population dynamics in relation to resource pulses can provide important insights into ecological processes at multiple ecological levels.

6. The effects of pastoralism and protection on lion behaviour, demography and space use in the Mara Region of Kenya

Abstract

Contraction of their historic geographic ranges and conflicts with humans underpins declines in large carnivore populations worldwide. These declines, which characterize pastoral systems where carnivores, people and livestock live in close contact, may be paralleled by changes in carnivore behaviour. We investigated this by comparing the behaviour, demography and space-use of three lion (Panthera leo) prides in the protected Masai Mara National Reserve and the adjoining Koyiaki pastoral ranch in southwestern Kenya during 2005–2006. The mean times lions were inactive was similar between the three prides except when the ranch lions were severely disturbed and became more nocturnal and inactive. The reserve lions ate their kills on open plains and returned to them often but the ranch lions did so only inside bushes and abandoned unfinished kills during a drought in 2005. The reserve lions spent most of their time on open plains while the ranch lions did so in bushes and woodlands. Activity budgets were similar between the prides regardless of land use. Adult lions altered not so much the type but the spatial location and timing of their behaviour on the pastoral ranches relative to the reserve.We discuss the implications of these findings for lion conservation on pastoral lands.Key words: behaviour, lions, pastoralism, protection, space use.
