Emerging evidence suggests that male lions are not dependent on female's hunting skills but are in fact successful hunters. But difficulty locating kills and objectively characterizing landscapes has complicated the comparison of male and female lion hunting strategies. We used airborne Light Detection and Ranging (LiDAR) measurements of vegetation structure in Kruger National Park, combined with global positioning system (GPS) telemetry data on lion, Panthera leo, kills to quantify lines-of…

Effects of Vegetation Structure on the Location of Lion Kill Sites in African Thicket
TLDR
It is demonstrated that vegetation structure is an important component of predator-prey interactions, with varying effects across ecosystems, and differences require consideration in terms of the ecological roles performed by predators, and in predator and prey conservation.
Can an herbivore affect where a top predator kills its prey by modifying woody vegetation structure?
TLDR
A conceptual framework is suggested whereby the relative importance of habitat features and prey abundance could change upon the scale considered, and how this can influence where African lions kill their prey is explored.
Zebra diel migrations reduce encounter risk with lions at night
TLDR
The effect of a predator-induced DM on the likelihood of encountering a predator is quantified and the effects of the DM on encounter risk are distinguished from those related to day/night changes in selection for vegetation types.
Habitat differences do not explain population declines of sable antelope in an African savanna
TLDR
There were no consistent differences in habitat features between the home ranges of current sable herds and areas formerly supporting herds and locally deteriorating habitat conditions were therefore not responsible for the decline in sables in this region of the park.
Zebra diel migrations reduce encounter risk with lions over selection for safe habitats
TLDR
The effect of a predator-induced DM in a terrestrial system on the likelihood of encountering a predator is quantified and the effects of the DM are distinguished from those related to day/night changes in selection for vegetation types.
Impact of risk on animal behaviour and habitat transition probabilities
TLDR
It is shown that proximity to lions influenced leopard habitat use, transition probability and behaviour, and this approach may have value to other systems, such as predator/prey interactions, or relationships between sympatric species, and at a scale hitherto not possible.
The devil is in the dispersers: predictions of landscape connectivity change with demography
Summary 1. Concern about the effects of habitat fragmentation has led to increasing interest in dispersal and connectivity modelling. Most modern techniques for connectivity modelling have resistance
Lions and leopards coexist without spatial, temporal or demographic effects of interspecific competition
TLDR
Results showed that both lion and leopard occupancy was independent of-rather than conditional on-their competitor's presence across all environmental covariates, suggesting that intraguild competitors can coexist in the same areas without population decline.
Rainfall driven changes in behavioural responses confound measuring trends in lion population size
Population size estimates must be comparable through time to interpret trends in threatened carnivore populations. Because prey distribution and dynamics drive carnivore distribution, and sampling
Habitat use and movement of proboscis monkeys (Nasalis larvatus) in a degraded and human-modified forest landscape
Proboscis monkeys (Nasalis larvatus) are endemic to Borneo and live in habitats threatened by land clearance for agriculture, aquaculture and timber. This thesis examines the roles of structural and

Planning for success: Serengeti lions seek prey accessibility rather than abundance
Summary 1. We used long-term radio-telemetry data to investigate how Serengeti lions ( Panthera leo ) distribute themselves with respect to hunting opportunities. Specifically, we investigate whether
Hunting by male lions: ecological influences and socioecological implications
TLDR
This study, the most intensive to date of male lion ecology, showed that in savanna woodlands, with high buffalo, Syncerus caffer, densities, male lions were frequent and successful hunters, and that in a range of ecosystems in southern and eastern Africa the proportion of time territorial males spent with, and thus scavenged from, their pride females was strongly influenced by vegetation structure.
Habitat use and movements of plains zebra (Equus burchelli) in response to predation danger from lions
TLDR
It was found that zebra abundance on or near a grassland patch was lower if lions had also been observed on that patch during the same day, and it was hypothesized that these more erratic movements assist zebras in avoiding detection or capture by lions.
Factors affecting the hunting success of male and female lions in the Kruger National Park
TLDR
It is concluded that in African ecosystems, the hunting success of male and female lions varies with a range of combinations of lion-, prey- and environment-related variables, and the hunting ability of male lions is demonstrated, which has perhaps been understated in other studies.
Cooperative hunting in lions: the role of the individual

TLDR
Individually identified lions (Panthera leo) were observed on the open, semi-arid plains in Namibia to assess cooperation and individual variation in hunting tactics and the role of cooperative hunting is discussed.
Behavioral adjustments of African herbivores to predation risk by lions: spatiotemporal variations influence habitat use.
TLDR
Results show that all herbivores tend to use more open habitats preferentially when lions are in their vicinity, probably an effective anti-predator behavior against such an ambush predator.
Estimating lion population variables: prey and disease effects in Kruger National Park, South Africa.
TLDR
The effect of an exotic disease on the Kruger lion population may be negligible at present, however, droughts could disrupt the hierarchical influences of prey biomass and bTB prevalence on lion densities and survival.
Elk alter habitat selection as an antipredator response to wolves
TLDR
The data support a central portion of the hypothesis that elk antipredator behavior could drive a trophic cascade in the Yellowstone ecosystem, but changes in elk numbers are also likely to have affected elk-plant interactions.
Trade-offs of predation and foraging explain sexual segregation in African buffalo.
TLDR
In an area with an intact predator community showed that male and female buffalo segregated by habitat and supported the predation-risk hypothesis, and male African buffalo appear to trade increased predation risk for additional energy gains in bachelor groups, which presumably leads to increased reproductive success.
Methods for Locating African Lion Kills Using Global Positioning System Movement Data
TLDR
Implementation of GLMs within an adaptive sampling framework can considerably increase efficiency of locating kill sites, providing a cost-effective method for increasing sample sizes of kill data.
