The Effects of Photoperiod and Food Intake on Reproductive Development in Male Deer Mice ( Peromyscus maniculatus)

Seasonal breeding is a tactic that has evolved in rodents that limits reproduction to specific times of the year to increase reproductive success. In order to time breeding accurately, many animals respond to changes in daily photoperiod. Short day lengths inhibit breeding in many nontropical rodent...

Description
Summary:Seasonal breeding is a tactic that has evolved in rodents that limits reproduction to specific times of the year to increase reproductive success. In order to time breeding accurately, many animals respond to changes in daily photoperiod. Short day lengths inhibit breeding in many nontropical rodent species. Restricted food availability can also inhibit reproductive function among some individuals in these so-called “photoperiodic” populations. Rodents born at the end of the breeding season typically delay sexual maturation until the following spring. Prepubertal rodents exposed to day lengths that are
