Abstract:Most of the amphibian's functional ecology studies focused on the difference between species and ignored the potential difference within species. However, increasing research started to recognize the importance of intraspecific variation in ecology and evolution. In the present study, we quantified the intraspecific variation in functional traits of Oreolalax omeimontis tadpoles. Our results indicated the high intraspecific variation in O. omeimontis tadpoles functional traits (mean coefficient variation=13.95%±12.79%), which was caused by ontogenetic change. This is because despite functional richness had no significant difference, functional identities differed significantly, and functional overlaps were extremely low between stages. These results indicated that different stages of O. omeimontis tadpoles occupied distinct functional niche, suggesting that different stages should be considered as distinct functional entities in future functional studies. Therefore, we suggest that intraspecific traits variability should be considered in future functional studies to enhance the ability of ecologists to understand and predict ecosystem functioning and ecological patterns.
