不同氧浓度下树麻雀形态和生理性状的可塑性初探
A Preliminary Study of the Plasticity of Morphology and Physiological Traits in Eurasian Tree Sparrows Under Different Oxygen Concentrations
摘要
Abstract
Hypoxia is one of the critical factors that affect the survival of animals inhabiting high-altitude environments.In order to investigate whether animals respond differently to varying oxygen concentrations,the present study examined the phenotypic plasticity of the Eurasian tree sparrows(Passer montanus),which were sampled from the Lasa region in 2024,under an experimental context of controlling oxygen concentrations.The results indicated,after the experiment,the Eurasian tree sparrows in the low oxygen group had significantly higher hemoglobin concentration and hematocrit than those in the normoxic group.Before and after the experiment,there were no significant changes in various measurement indicators of sparrows in the normoxic group;the sparrows in the hypoxia group significantly reduced their body weight and fasting blood glucose concentration,but there were no significant changes in hemoglobin concentration and hematocrit.In addition,the chest muscles and lungs of the sparrows in the low oxygen group were relatively heavier,though the differences did not reach a significant level.关键词
