主 题：environmental adaptation Phrynocephalus Qinghai-Tibetan Plateau sexual dimorphism stable isotope
摘 要：The plateau environments are typically arid,cool,and high altitude,posing formidable challenges to wildlife survival due to resource scarcity and harsh *** ecological adaptability in severe conditions requires a deeper understanding of the niche characteristics of plateau *** niche,which is a comprehensive indicator describing the energy acquisition strategy of animals,remains relatively understudied in plateau ***,by combining stable isotopes and morphological data,we quantified the trophic niches of two allopatric lizard species(Phrynocephalus vlangalii and ***)that live in the hinterland of the Qinghai–Tibetan Plateau,and explored how their trophic niches correlate with morphological and environmental *** both trophic niche and morphological traits were similar between species,noteworthy distinctions were observed between male and female Phrynocephalus *** morphological traits associated with predation(*** length and head size)and reproduction(*** length),annual mean temperature,and sex played influential roles in shifting trophic *** results imply that sexual dimorphism may facilitate inter-sex divergence in resource utilization,leading to trophic niche variations in the highland ***,extreme environmental stress can constrain interspecific divergence in morphological and trophic *** findings illustrate the dynamic variations of trophic niches in highland lizards,contributing to a more comprehensive understanding of the adaptation strategies employed by lizard species in plateau environments.
