Untangling the oxidative cost of reproduction: An analysis in wild banded mongooses

open access: yesEcology and Evolution, Volume 12, Issue 3, March 2022., 2022
The cost of reproduction plays a central role in evolutionary theory, but the identity of the underlying mechanisms remains a puzzle. Oxidative stress has been hypothesized to be a proximate mechanism that may explain the cost of reproduction. We examine three pathways by which oxidative stress could shape reproduction using data from a long‐term food ...
