Behaviorally induced maternal stress in a fish influences progeny quality by a hormonal mechanism.

From: Ecology | Date: September 1, 1998| Author: | Copyright information

The survival and quality of progeny can be strongly influenced by nongenetic effects derived from the physiological condition of the mother during gametogenesis. The influence of maternal condition on the size and quality of larvae at dispersal was examined for the tropical damselfish, Pomacentrus amboinensis, through a series of field studies during 1994. In this species, males guard a demersal nest of eggs contributed to by nearby females. The largest and most dominant female stays near the nest and contributes most to the egg clutches, limiting egg contributions from subordinate females. ...
