The paper tests the crepuscular-cathemeral bridge hypothesis by comparing activity patterns in aquatic and terrestrial artiodactyls, finding support for the bridge and distinct roles of crepuscularity and cathemerality.

The paper shows that social and environmental cues mask circadian activity patterns in shell-dwelling cichlid fish, revealing new relationships between circadian rhythms and sociality.

This study examines yawn functions in juvenile Emperor cichlids, finding support for arousal, social contagion, and sex-specific differences in yawn timing and frequency.

This study shows that temporal niche partitioning, through distinct activity patterns, contributed to the adaptive radiation of cichlid fishes in Lake Tanganyika.
