UV-Induced Fluorescence in the Balance: Mate Choice and Predation Risk in the Female Ornamented Jumping Spiders.
The adaptive significance of female ornamentation remains a central question in evolutionary biology, with ultraviolet (UV)-induced fluorescence emerging as a key area of interest. This study investigates the potential adaptive advantages of female-specific UV-induced fluorescence in male mate choice and predation risk, as fitness costs, using two species of ornate jumping spiders Phintella vittata and Ph. bifurcilinea. In these species, the palps of adult females exhibit UV-induced fluorescence, offering a compelling model to explore the interplay of sexual and natural selection acting on female ornamentation. In male mate-choice trials, males were presented with a choice between a fluorescent (F+, UV-visible) and a non-fluorescent (F-, UV-blocked) female. Males showed pronounced mate preference for F+ females over F- females, that is, spending significantly more time interacting with F+ females, suggesting that fluorescence serves as a sexually selected signal. To assess the potential costs of fluorescence, we tested its effect on predation risk using the spider-eating jumping spider Portia xishan as a predator under F+ and F- conditions. Predation rates were significantly higher for F+ females than for F- females, indicating that UV-induced fluorescence increases detectability by predators. These findings provide empirical evidence of a trade-off: While fluorescence enhances male mate preference, it also increases predation risk. This study is the first to demonstrate the dual roles of fluorescence in sexual signaling and predation in female jumping spiders, challenging traditional male-centric perspectives on mate choice. By integrating behavioral and ecological approaches, this work offers new insights into the evolutionary trade-offs associated with female sexually selected traits.
期刊介绍:
The official journal of the International Society of Zoological Sciences focuses on zoology as an integrative discipline encompassing all aspects of animal life. It presents a broader perspective of many levels of zoological inquiry, both spatial and temporal, and encourages cooperation between zoology and other disciplines including, but not limited to, physics, computer science, social science, ethics, teaching, paleontology, molecular biology, physiology, behavior, ecology and the built environment. It also looks at the animal-human interaction through exploring animal-plant interactions, microbe/pathogen effects and global changes on the environment and human society.
Integrative topics of greatest interest to INZ include:
(1) Animals & climate change
(2) Animals & pollution
(3) Animals & infectious diseases
(4) Animals & biological invasions
(5) Animal-plant interactions
(6) Zoogeography & paleontology
(7) Neurons, genes & behavior
(8) Molecular ecology & evolution
(9) Physiological adaptations
