Comprehensive study reveals nocturnal mating benefits low-ranking males in Tibetan macaques, suggesting alternative reproductive strategies.
Key Points
This research aims to explore nocturnal mating behavior patterns and influencing factors in Tibetan macaques, focusing on low-ranking males' strategies.
Conducted a 4-year study on free-ranging Tibetan macaques at Mount Huangshan, China.
Utilized 4 G solar-powered night-vision cameras for systematic documentation.
Analyzed mating behavior occurrences and durations during nocturnal versus diurnal periods.
Nocturnal mating behavior shows a bimodal distribution.
Mating success at night is similar for high- and low-ranking males, providing subordinates increased opportunities.
Nocturnal non-force mating events are significantly higher in low-ranking males.
Lunar illumination positively correlates with nocturnal mating frequency.
