A preliminary examination of burrow use of the understudied Ctenomys pilarensis in Ñeembucú, Paraguay

Abstract

Abstract Very little is known on Ctenomys pilarensis, as it has rarely been studied. We conducted a preliminary study on its burrow use by implementing a capture-mark-recapture method. Between February and June 2022, 12 different Pilar tuco-tucos were captured and chipped using MiniHPT8 PIT tags, 7 individuals were recaptured at least once. Our results indicate this species to be solitary, as we found no evidence of burrow sharing. These findings should, however, be viewed with caution due to our small sample size.
