Short Abstract

Recent genetic findings suggest that trashline behavior and short circadian clocks evolved independently in two spider species, Cyclosa turbinata and Allocyclosa bifurca. To investigate this phenomenon, the circadian rhythm of Cyrtophora citricola was analyzed and compared to that of A. bifurca. The study found that C. citricola has a typical 24-hour circadian rhythm, suggesting that the short clock behavior in the A. bifurca lineage may be ecologically linked to their trashline behavior.
