A gradual release of metabolic suppression during diapause termination in a montane insect
Meeting Abstract 100-1 Monday, Jan. 6 13:30 – 13:45 A gradual release of metabolic suppression during diapause termination in a montane insect ROBERTS, KT*; WILLIAMS, CM; Univ. of California, Berkeley; Univ. of California, Berkeley kevrob@berkeley.edu To conserve energy during winter many insects enter diapause, a dormant state in which metabolic rate is suppressed. Metabolic suppression is gradually […]
