- Description: Although the leopard (Panthera pardus) has the widest range of any felid in the world is designated as a vulnerable species, mainly because of human-induced conflict (Jacobson et al., 2016). Our study focuses on a population of leopards on privately owned, mixed-use farmland (Baviaanskloof Hartland–BH hereafter) which is adjacent to the Baviaanskloof Mega Reserve (BMR) in the Baviaanskloof UNESCO World Heritage Site of the Eastern Cape, South Africa. Given the unique make-up of the region, with sometimes conflicting management objectives, the status of leopards in the broader Baviaanskloof is of particular interest to a range of stakeholders. However, despite the need for management decisions to be based on reliable and regular population monitoring efforts (Elliot et al., 2020), the last formal assessment of the leopard population in the Baviaanskloof was performed in 2011/2012 but published 9 years later (Devens et al., 2018). The only other assessment of the status of leopards in the region was an unpublished Master's project (McManus, 2009). Here, we use photographic captures of leopards and a Spatially Explicit Capture Recapture (SECR) analytical framework in the mixed-use BH region of the Baviaanskloof to generate an up-to-date leopard population density estimate that can inform conservation management of the species in this important World Heritage Site.

- Description: Puma (Puma concolor) is a wide-ranging, large felid species, and site-specific research on its diet is important for local management. Like the diets of other large felids, puma diets may differ between sex due to size dimorphism and between seasons due to changes in prey vulnerability and availability. We investigated the influence of sex and season on puma diet in southwest New Mexico in terms of prey species and size categories. Pumas (10 males, 6 females) were tracked with GPS collars for an average of one year per individual between February 2008 and July 2020. Puma location was recorded every 2 hours between 19:00 and 7:00, and kill sites were identified by a minimum of 2 GPS fixes occurring within 100 m and 100 hours of the first fix. Pumas specialized on mule deer (Odocoileus hemionus) and elk (Cervus elaphus) but also preyed upon a range of other species of different sizes. The probability of making a medium-sized kill such as a mule deer was higher for females than for males, while the probability of making an extra-large kill, such as an elk, was considerably greater for males than for females. There was substantial variation in prey species and size categories killed by individual pumas, particularly of smaller-sized prey like collared peccary (Pecari tajacu) and skunks (e.g., Spilogale gracilis, Mephitis mephitis). Our findings concur with previous research on the importance of mule deer and elk in puma diet, demonstrate individual variation in prey killed, and may have management implications.
