Ecology of the Aardvark (Orycteropus Afer) in Western Africa

Diplomová práce

Abstract:

The aardvark (Orycteropus afer) is a widespread species across sub-Saharan Africa and is currently classified as Least Concern by the IUCN Red List. However, due to its nocturnal and elusive behaviour, population estimates remain largely unknown, and the species remains poorly studied despite its ecological importance. Ongoing habitat change, climate variability, and increasing human pressure highlight the need to better understand the factors influencing this species. To address these knowledge gaps, this study investigates aardvark occupany in two protected areas within the West African savanna: Niokolo-Koba National Park and Pendjari National Park. Using camera trap data, we examined environmental and anthropogenic factors affecting aardvark spatial patterns. Occupancy modelling and prediction of occurrence were conducted using the spOccupancy package in RStudio. Additionally, temporal activity patterns were analysed at both sites and compared with findings from studies in southern Africa. The results indicate a significant negative combined effect of terrain roughness and climatic variables at both study sites, suggesting complex environmental influences on aardvark spatial preferences. Temporal analyses confirmed predominantly nocturnal activity, with minor differences between sites. In contrast, human pressure did not show a significant effect, although this may reflect limitations in the available camera traps records and environmental data. Given the limited research on aardvarks in the West African savanna, this study contributes to a better understanding of their spatial and temporal ecology in the region. It also highlights the remaining knowledge gaps and underscores the need for further research, particularly given limitations in detecting elusive species.
