Proximity to humans affects local social structure in a giraffe metapopulation
Experimental laboratory evidence suggests that animals with disrupted social systems express weakened relationship strengths and have more exclusive social associations, and that these changes have functional consequences. A key question is whether anthropogenic pressures have a similar impact on the social structure of wild animal communities. We addressed this question by constructing a social network […]
Assessing transmission of antimicrobial-resistant Escherichia coli in wild giraffe contact networks
There is growing evidence that anthropogenic sources of antibiotics and antimicrobial-resistant bacteria can spill over into natural ecosystems, raising questions about the role wild animals play in the emergence, maintenance, and dispersal of antibiotic resistance genes. In particular, we lack an understanding of how resistance genes circulate within wild animal populations, including whether specific host […]
Seasonal changes in social networks of giraffes
Fission-fusion social societies allow animals to respond in a flexible manner to environmental changes by adapting the size and composition of a group. Although group members change frequently in these systems, associations with preferred partners may be found. In this study, we examined the grouping patterns of a population of 80 individual giraffes in a […]
Giraffe social preferences are context dependent
The dynamic nature of animal societies often hides multiple layers of complexity. The field of animal behaviour is rapidly advancing with the development of increasingly sophisticated analytical methods that allow scientists to identify complex and nuanced drivers of social patterns. The resurgent interest in giraffe sociality illustrates this by challenging the early view that individuals […]
A study on the social organisation of the Southern giraffe (Giraffa camelopardalis giraffa)
In this study, I have investigated the social structure of a population of the Southern giraffe (Giraffa camelopardalis giraffa) residing in Pilanesberg National Park, South Africa. To do so, association data was collected using photo-identification to recognise individual giraffes. Within the study period between October 27th 2012 and January 25th 2013, 257 groups of giraffes […]
Multilevel social organization and space use in reticulated giraffe (Giraffa camelopardalis)
It is increasingly recognized that association patterns of most gregarious animals are nonrandom. However, nonrandom patterns can emerge in any population that exhibits spatial structure, even if individuals associate randomly. In species that lack clearly differentiated social relationships characteristic of socially complex mammals, space use patterns must be considered alongside association patterns in order to […]
