Wildlife Letters, EarlyView.Common cuckoo nestlings from different populations show varying degrees of mimicry of warbler begging calls, with the Yongnianwa population being the most accurate and the Zhalong population the least. Overall, these cuckoos employ a dual strategy: they conservatively mimic the high‐frequency components of host calls while adaptively adjusting their ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowers with deep corollas are frequently associated with nectar robbing, a behaviour that often reduces pollen transfer and seed production. Robbing scars, however, may further affect plant reproductive success through rainwater entry into corolla tubes.

Wildlife Letters, Volume 4, Issue 3, Page 131-138, September 2026.Using a 3‐year, broad‐scale camera‐trap network in western Kansas, we tested whether coyotes and American badgers exhibit spatiotemporal patterns consistent with coordinated hunting. Despite high diel activity overlap, detection‐conditioned co‐detections occurred far less frequently than expected under independence, and short‐term temporal sequencing ...

丰容对白臀叶猴(Pygathrix nemaeus)的采食量及行为影响
野生动物学报, 2017 对南宁市动物园的3只白臀叶猴(Pygathrix nemaeus)进行笼舍环境丰容和食物丰容,采用瞬时取样和焦点取样法相结合的方式,探讨丰容前后动物的采食量和各种行为变化。研究表明,环境丰容对白臀叶猴行为的影响明显,其中积极行为的时间增加,刻板行为、异常行为显著降低,而独笼圈养的雄性白臀叶猴的一般行为变化不明显,其余2只白臀叶猴的一般行为均增加。食物丰容仅促进了白臀叶猴在采食时增加了探究行为和其他积极行为,对每天的采食量无影响。
