9321458 Full This project addresses a question of major interest to physiological ecologists: does physiological capacity reflect performance in nature? Precise measurements of locomotion in nature will test predictions based on laboratory measurements of the energetics underlying endurance capacity in a nocturnal lizard, the banded gecko (Coleonyx variegatus). Nocturnal lizards represent a substantial evolutionary shift in environment. Nocturnality imposes a thermal handicap, which constrains endurance capacity to submaximal levels. Nocturnal geckos have evolved excellent fuel economy, which partially offsets the thermal handicap. In this dissertation research project, Mr. Autumn will use infrared video motion analysis to obtain quantitative measurements of frequency, speed, and duration of locomotion of banded geckos in the field. He will test the hypothesis that natural performance loads are limited by nocturnality, yet exceed the capacity of comparable diurnal lizards. This project will complete a picture that links (1) effects of evolution of environment on physiological capacity with (2) effects of evolution of physiological capacity on performance in nature. ***

9321458 Full这个项目解决了生理生态学家主要感兴趣的问题：生理能力是否反映了自然界的表现？对自然界运动的精确测量将检验基于实验室对夜行蜥蜴——带状壁虎（Coleonyx variegatus）耐力能力的能量学测量的预测。夜行蜥蜴代表了环境的重大进化转变。夜间活动造成热障碍，将耐力限制在次极限水平。夜行壁虎进化出了出色的燃油经济性，这部分抵消了热障碍。在本论文的研究项目中，Mr. Autumn将使用红外视频运动分析来获得野外带状壁虎运动的频率、速度和持续时间的定量测量。他将测试这样一个假设，即自然性能负荷受到夜间活动的限制，但却超过了同类白天活动的蜥蜴的能力。本项目将完成(1)环境演化对生理能力的影响与(2)生理能力演化对自然界表现的影响的联系。＊＊＊
