Aardvarks, scientifically known as Orycteropus afer, are more than just large, nocturnal mammals residing in sub-Saharan Africa. Instead, they play a critical role in maintaining the ecosystem. By dining on termites, they help prevent the destruction of human-built structures. Additionally, aardvarks act as ecosystem engineers, similar to beavers, as they construct large tunnels underground. These burrows don’t just provide shelter for the species but also offer protection to other wildlife. Furthermore, extensive studies have revealed that the findings from their waste can offer valuable insights into how climate change is affecting these elusive creatures.

In a study published on December 13 in the journal Diversity and Distribution, researchers discussed the impact of aridification on aardvark populations. By analyzing months of poop samples, they discovered that the drying and heating of the species’ landscape is leading to their isolation. This, the study emphasizes, could have serious implications for the long-term survival of aardvarks.
“The lack of substantial studies focusing on aardvarks prompted our research. The species is widely acknowledged for its ecological significance, yet little is really known about them,” stated Clint Epps, a wildlife biologist at Oregon State University and co-author of the study. “The primary objective was to gather sufficient data to initiate a comprehensive understanding of this species,” Epps explained in a recent statement.
Aardvarks are often likened to pigs, but in reality, they are unique, burrowing nocturnal creatures that reside primarily throughout the southern two-thirds of Africa. Despite their rather elusive nature, they are considered a species of least concern by the IUCN Red List, predominantly due to their diverse range of habitats. However, their real population trends and distribution remain somewhat of a mystery, given the challenge of accurately studying them within large and often remote landscapes.
“In the face of rapid environmental change, it becomes increasingly crucial to evaluate and understand changes across the landscape that houses a particular species. This is essential for making well-informed decisions related to conservation and management,” stresses Rachel Crowhurst, a wildlife geneticist at Oregon State University and co-author of the study.
Past studies have delved into aardvark DNA, primarily to explore the evolution of mammals, but the new research focused on wild aardvark populations, contributing novel findings about these mysterious animals.
Unveiling more intriguing aspects of aardvarks, the researchers shared that these creatures are challenging to study. Their nocturnal nature, low population density, and remote habitats make them an elusive subject of study. To add to their mystique, aardvarks have a unique trait of burying their own excrement, making it even more challenging for researchers to collect accurate data.

Despite the challenges, researchers have been committed to unraveling the mysteries of aardvarks. Their dedication to the cause reveals a deep desire to uncover critical information about often overlooked species. All in all, aardvarks captivate the imagination and peak scientific curiosity, motivating researchers to conduct thorough and innovative studies in hopes of preserving these unique creatures.
