The impacts of management interventions on the sociality of African lions (Panthera leo): implications for lion conservation
<ol> <li>African lion (<em>Panthera leo</em>) populations normally consist of several neighbouring prides and multiple adult males or groups of males that interact competitively. In large, open systems, cub defence from infanticidal males and territory defence drive group living in lions. However, in smaller (< 1,000 km<sup>2</sup>), fenced wildlife reserves, opportunities for natural immigration and emigration are limited which means that the evolutionary drivers of lion sociality may collapse.</li> <li>Here, we use lion behavioural data collected from 16 wildlife reserves across South Africa to test how management-induced ecological conditions alter lion social dynamics.</li> <li>The number of lionesses observed together was best predicted by pride size, prey biomass and biome. Lionesses were less likely to group together as pride size increased, but more likely to group together as prey biomass and habitat productivity increased. In addition, adult males were observed more frequently with prides that had young (< 12 months) cubs in reserves that had unfamiliar adult males present compared to reserves without any unfamiliar adult males.</li> </ol> <p>Our results demonstrate how intra-specific competition between lions drives their sociality, and this may break down in small, fenced wildlife reserves where lions are actively managed. Although small, fenced reserves in South Africa have made a significant contribution to increasing lion numbers on the continent, our work highlights several important ecological implications of active lion management. For wildlife managers, mimicking the outcomes of different levels of intra-specific competition is likely a critical management tool for the persistence of lions in small reserves.</p>

Dataset of: Community perspectives on the prospect of lion (Panthera leo) reintroduction to Comoé National Park, Côte d'Ivoire (West Africa)
<p><span>The civil war in Côte d'Ivoire led to a hike in human disturbances and the extirpation of the African lion (<em>Panthera</em> <em>leo</em>) from the Comoé National Park (CNP). After the war, many efforts have been made to restore this ecosystem and management is considering the reintroduction of lions. In participatory management with people at the center of conservation, there is a need to discuss with communities the initiatives affecting their livelihoods. We assessed the acceptance of lion reintroduction by the local communities; through semi-structured questionnaires to 307 volunteer participants in surrounding 23 villages. Most respondents had knowledge of lions from CNP (93%, n=286). A generalized linear model (GLM) revealed that </span><span>sex, profession, perceived benefits and risks, and an appreciation of the current management system are the main significant determinants for the acceptance of lion reintroduction in CNP.</span><span> A large majority (73%, n=223) were in favor of the lion reintroduction with significant variance among socio-professional categories. The majority of respondents (81%, n=250) acknowledged having coexisted with lions, with previous lion conflicts reported by 20% (n = 61), and a willingness to coexist in the future by 74% (n = 227). More than 84% (n=260) believed that there would be benefits associated with lion reintroduction to CNP and 53% (n=162) believed that the potential benefits would be greater than the possible risks associated with lions. Most respondents (88%; n=270) confirmed the possibility of taking precautions to prevent future lion attacks. While only 42% (n = 129) of respondents felt that current management was participatory, most of them felt that it was acceptable (83%; n = 254). </span><span>Our data shows a large degree of lion support, positive perceptions, and willingness to coexist with lions in the future. These results form part of a fundamental step in the direction for ethical reintroduction, as described by the IUCN reintroduction specialist group</span><span>. </span><span>We recommend the improvement of the involvement of indigenous communities in potential reintroduction of lions, especially the pastoralists, and the sharing of any associated benefits.</span></p>

Coexistence from a lion's perspective: Movements and habitat selection by African lions (Panthera leo) across a multi-use landscape
<p>Diminishing wild space and population fragmentation are key drivers of large carnivore declines worldwide. Persistence of large carnivores in fragmented landscapes often depends on the ability of individuals to move between separated subpopulations for genetic exchange and recovery from stochastic events. Where separated by anthropogenic landscapes, subpopulations' connectivity hinges on the area's socio-ecological conditions for coexistence and dispersing individuals' behavioral choices. Using GPS-collars and resource- and step-selection functions, we explored African lion (<em>Panthera leo</em>) habitat selection and movement patterns to better understand lions' behavioral adaptations in a landscape shared with pastoralists. We conducted our study in the Ngorongoro Conservation Area, Tanzania, a multiuse rangeland, that connects the small, high density lion subpopulation of the Ngorongoro Crater with the extensive Serengeti lion population. Landscape use by pastoralists and their livestock varies seasonally, driven by the availability of pasture, water, and disease avoidance. The most important factor for lion habitat selection was the amount of vegetation cover, followed by the distance to human settlements and the interaction between those two variables, with selectivity strengths varying with season and time of day. All lions were more willing to approach human settlements at night and during the dry season, selecting strongly for cover when moving closer to humans during the day. Resident females most consistently used areas close to humans, but also relied more consistently on cover than males. Connectivity of lion subpopulations, facilitated by nomadic males, does not appear to be blocked by sparse pastoralist settlements and nomadic males avoided humans on the landscape more strongly than did resident lions. These results are consistent with lions balancing risk from humans with exploitation of livestock by altering their behaviors to reduce potential conflict. Our study lends some optimism for the adaptive capacity of lions to promote coexistence with humans in shared landscapes.</p>

Data from: Gigantic lion, (Panthera leo), from the Pleistocene of Natodomeri, eastern Africa
The partial skull of a lion from Natodomeri, northwest Kenya is described. The Natodomeri sites are correlated with Member I of the Kibish Formation, dated to between 195 ka and ∼205 ka. The skull is remarkable for its very great size, equivalent to the largest cave lions (<i>Panthera spelaea</i>) of Pleistocene Eurasia and much larger than any previously known lion from Africa, living or fossil. We hypothesize that this individual represents a previously unknown population or subspecies of lion present in the late Middle and Late Pleistocene of eastern Africa rather than being an indication of climate-driven size increase in lions of that time. This raises questions regarding the extent of our understanding of the pattern and causes of lion evolution in the Late Pleistocene.
