Nigeria Field Update 2024: Integrative Disease Ecology Field Season Successfully Completed!

Our second field season in Nigeria wrapped up this summer after an intensive seven months of bat surveys and sampling (November 2023 – June 2024). Ben led a field team of 15 to survey 17 caves across two sites in southern Nigeria sampling 1266 bats. This work is part of our larger collaborative effort to understand how human disturbance affects the complex relationships between bats, their environment, and their host viruses – critical knowledge for predicting and preventing viral spillover events. While focusing on the ever-cute Egyptian fruit bat (Rousettus aegyptiacus), the team also sampled other 17 bat species including the beautiful Otomops martiensseni, a new country record for Nigeria!

Perhaps most importantly, this field season significantly strengthened the local capacity for bat research in Nigeria. Tigga and Dr. Simon Anthony were there to train field team on biosafety, sampling techniques etc.

The field season came with its fair share of challenges—maintaining cold chains for sample preservation was no cakewalk, with liquid nitrogen sources a bone-rattling 10-hour drive away. Add that to the logistical hurdles of hauling a 15L liquid nitrogen-charged dry shipper up and down a steep mountain, requiring a grueling 9-hour hike each way. But the dedication of the field team, especially our Nigerian colleagues, made it all fun.
