1. Stress exposure increases glucocorticoid in P. domesticus.

   “there were some effects of the treatment on glucocorticoid levels and mass dynamics”

2. Stress exposure has no effect on telomere length in P. domesticus.

   “there were no effects on telomeres during any of the 6-11-month studies”

1. Anthropogenic noise increases reproductive schedule acceleration in P. domesticus.

   “Males reared in a noisy environment had accelerated reproductive schedules, supporting a sex-specific internal PAR hypothesis.”

2. Anthropogenic noise decreases annual reproductive output in P. domesticus.

   “Females that hatched in a noisy environment produced fewer genetic recruits annually, supporting a sex-specific silver spoon hypothesis.”
