Photo-refractoriness reflects bet-hedging strategies deployed in unpredictable environments in male Brandt's voles.

ABSTRACT: Day length, also known as photoperiod, is an important reproductive regulatory factor in most seasonal breeders. Brandt's vole, a long-day breeder, exhibits significant differentces in reproductive development depending on the photoperiod of the season of birth, as is seen in other rodent seasonal breeders. However, there is a lack of comprehensive studies on the effects of photoperiod across different seasons. In the present study, we investigated the impact of long (LP) and short photoperiod (SP) on postnatal development in male voles. We measured somatic and testicular parameters from weaning at three postnatal weeks (PNW3) to PNW19, weighed testis mass from birth, and confirmed the status of testicular development by observing the histological features of the seminiferous epithelium.
