Relative Importance of Sex, Pre-Starvation Body Mass and Structural Body Size in the Determination of Exceptional Starvation Resistance of Anchomenus dorsalis (Coleoptera: Carabidae)

Popis výsledku v původním jazyce

In nature, almost all animals have to cope with periods of food shortage during their lifetime. Starvation risk is especially high for carnivorous predatory species with often quite long intervals between particular successful prey capture events. A laboratory experiment using the predatory carabid beetle Anchomenus dorsalis revealed exceptional starvation resistance in this species: males survived up to 137 days and females up to 218 days without food at 20C. Individual starvation resistance was positively affected by pre-starvation body mass, but not by beetle structural body size per se. Females outperformed males even when the effect of gender was corrected for the effects of structural body size and pre-starvation body mass. Better performance of females compared to males and of beetles with higher relative pre-starvation body mass could be linked to higher fat content and lean dry mass before starvation followed by a higher decrease of both during starvation. There was also a difference between
