摘要: The effect of the reliability available social information was assessed by examining whether age changes its effects on a foraging decision in group-living fish Gambusia affinis. Individuals switched their patch preference when faced with that conflicted personal general; information, however, did not significantly influence for feeding patch. mass makers positively correlated use heavier individuals exhibiting greater difference than lighter individuals, suggesting large and small G. affinis trade-off benefits acquisition costs competition from conspecifics differently.
