Behavioral correlates between daily activity and sociality in wild and captive origin African lions
Study of behavioral correlations within and across populations has long been of interest to ethologists. An exploration of behavioral correlations between sociality and behavior of African lions (Panthera leo) was undertaken to examine if this approach is better able to reveal important aspects of lion behavior not easily discernible by looking at these behaviors separately. Resting behavior and received play interactions were correlated in 2 captive-origin prides and one wild pride, attributable to the involvement of cubs and sub-adults. Direct and exploratory movement was negatively correlated with groom centrality in 2 of the 3 prides, due to adults engaging in high levels of both of these activities. Exploration of these behavioral correlations highlighted the differences between age-groups in activity and sociality, facilitating the understanding of the complex behavior and interactions of lions. In addition, the finding of similar behavioral correlations between captive-origin and the wild prides provides confidence in the suitability if captive-origin candidates for ex-situ release. This is imperative to ensure the success of sub-groups and prides under an ex-situ reintroduction program
Examining the role of television programmes in legitimising inherited wealth and privilege for the super-rich in a society that values meritocracy
From Caves to the Savannah, the Mitogenome History of Modern Lions (Panthera leo) and Their Ancestors
Lions (Panthera leo) play a crucial ecological role in shaping and maintaining fragile ecosystems within Africa. Conservation efforts should focus on genetic variability within wild populations when considering reintroduction attempts. We studied two groups of lions from two conservation sites located in Zambia and Zimbabwe to determine their genetic make-up, information that is usually unknown to the sites. In this study, we analysed 17 specimens for cytb and seven microsatellite markers to ascertain family relationships and genetic diversity previously obtained by observational studies. We then produced a standardised haplogroup phylogeny using all available entire mitogenomes, as well as calculating a revised molecular clock. The modern lion lineage diverged ~151 kya and was divided into two subspecies, both containing three distinct haplogroups. We confirm that Panthera leo persica is not a subspecies, but rather a haplogroup of the northern P.l. leo that exited Africa at least ~31 kya. The progenitor to all lions existed ~1.2 Mya, possibly in SE Africa, and later exited Africa and split into the two cave lion lineages ~175 kya. Species demography is correlated to major climactic events. We now have a detailed phylogeny of lion evolution and an idea of their conservation status given the threat of climate change
âYou come back fighting. Thatâs what gives you the drive to achieveâ: The extraordinary psychological construction of the super-rich in entertainment documentaries
Inequality in society is legitimised through the âmeritocracy mythâ and existing research claims that the affluence of the super-rich is the result of their superior traits. Discursive Social Psychology examines the ways in which psychological concepts such as personality traits function in talk. This research explores how entertainment documentaries construct the traits of the super-rich to legitimise their wealth. A corpus of 41.5 hours of terrestrial UK televised broadcasts that used the term, âsuper-richâ was analysed. This explored how wealthy individuals are presented as having superior psychological qualities compared to the general public in relation to their greater drive and resilience. However, wealthy individuals also talk about the development of superior traits as a response to adversity. Entertainment documentaries draw upon individualistic ideology to present wealth inequality as a natural consequence of individual differences and as a result, the current distribution of wealth is âjustâ despite its negative consequences for all
Patch - Occupancy Survey of Elephant (Loxodonta africana) Surrounding Livingstone, Zambia
Wild elephants represent the biggest humanâwildlife conflict issue in Livingstone, Zambia. However, little is known about their movements. This survey investigated elephantsâ habitat use outside a core protected and fenced zone that forms part of Mosi-oa-Tunya National Park, Zambia. Using âpatch-occupancyâ methodology, indications of elephant presence (feeding behaviour, dung and tracks) were surveyed. The survey aimed to assist proposed future monitoring exercises by defining the geographical extent that should be considered to improve accuracy in species abundance estimates. Results were supplemented using collected indications of elephant presence from prior monitoring exercises, and during this survey. Elephant presence was confirmed up to 8 km from the boundary of the protected core habitat, focussed in: (1) an unfenced zone of the national park, (2) along a road leading from the national park to the Dambwa Forest to the north and (3) along two rivers located to the west (Sinde River) and east (Maramba River) of the core area. Detection probability of elephant presence was high using these methods, and we recommend regular sampling to determine changes in habitat use by elephants, as humans continue to modify land-use patterns.
Conservation implications: Identification of elephant ranging behaviour up to 8 km outside of the Mosi-oa-Tunya National Park in southern Zambia will assist in managing humanâ elephant conflict in the area, as well as in assessing this seasonal populationâs abundance
A social network analysis of social cohesion in a constructed pride: Implications for ex situ reintroduction of the African Lion (Panthera leo)
Animal conservation practices include the grouping of captive related and unrelated individuals to form a social structure which is characteristic of that species in the wild. In response to the rapid decline of wild African lion (Panthera leo) populations, an array of conservational strategies have been adopted. Ex situ reintroduction of the African lion requires the construction of socially cohesive pride structures prior to wild release. This pilot study adopted a social network theory approach to quantitatively assess a captive pride's social structure and the relationships between individuals within them. Group composition (who is present in a group) and social interaction data (social licking, greeting, play) was observed and recorded to assess social cohesion within a released semi-wild pride. UCINET and SOCPROG software was utilised to represent and analyse these social networks. Results indicate that the pride is socially cohesive, does not exhibit random associations, and the role of socially influential keystone individuals is important for maintaining social bondedness within a lion pride. These results are potentially informative for the structure of lion prides, in captivity and in the wild, and could have implications for captive and wild-founder reintroductions
