The paper shows that mole rats accumulate neuromelanin with age, suggesting that long-lived rodents develop this pigment, while short-lived rodents like mice and rats do not reach detectable levels due to their shorter lifespans.

This study investigates whether the seasonal polyphenism in Araschnia levana is driven by thermoregulation, finding that morphology and coloration influence thermal dynamics but no active thermoregulation occurs.
