Spotted hyena navigation of social-ecological landscapes on a
coexistence frontier
Abstract
“Coexistence frontiers”, or regions where human infrastructure and
activity are increasing rapidly or newly appearing, constitute novel
environments where wildlife must learn to navigate and coexist with
people. It is widely recognized that behaviorally flexible species are
more likely to persist in these human-dominated landscapes.
Nevertheless, we do not fully understand how these animals navigate
landscapes shaped by infrastructure, human activity, and human
tolerance. As a widely reviled and behaviorally plastic apex predator,
the spotted hyena (Crocuta crocuta) is a model species for understanding
how wide-ranging large carnivores navigate social-ecological landscapes
in an urbanizing world. Using high-resolution (minimum 5-min fix rates)
GPS collar data and supplemental camera trap imagery, we applied
resource selection and step selection functions to assess spotted hyena
landscape navigation and fine-scale movement decisions in relation to
social-ecological features in Lake Nakuru National Park and Soysambu
Conservancy, Kenya. Second, we used camera traps and barrier behavior
analysis (BaBA) to further examine hyena interactions with barriers. Our
results show that environmental covariates—including NDVI, terrain,
and proximity to water—were the best predictors of landscape-scale
resource selection by hyenas, while human infrastructure and the
likelihood of conflict with humans or livestock predicted fine-scale
hyena movement decisions. We also found that hyena selection for these
characteristics changed seasonally and across land management types.
Camera traps documented an exceptionally high number of individual
spotted hyenas (234) approaching the national park fence at 16 sites
during the study period, and BaBA results suggested that hyenas perceive
protected area boundaries’ electric fences as risky but may cross them
out of necessity. Our results highlight that wildlife adaptability in
coexistence frontiers may be expressed differently depending on context
and scale. These results also point to the need to incorporate societal
factors into multiscale analyses of carnivore movement to effectively
plan for human-carnivore coexistence.
