..., such as Siberian hamsters ( Phodopus sungorus ), are more aggressive during the short-day photoperiods of the non-breeding season, despite gonadal regression. While our previous data suggest that Siberian hamsters employ a ‘seasonal switch’ from gonadal to adrenal regulation of aggression during short-day...

Our results suggest a U-shaped dependence of social isolation-induced aggressive behavior on Dsk signaling...

However, differences in cuticular chemical signatures linked to fertility status accurately predicted the probability of behaving...
