Many aspects of physiological and organismal performance vary with some continuous environmental variable: e.g., photosynthetic rate as a function of light intensity; growth rate or sprint speed as a function of temperature. For such 'performance curves', the environment plays two roles: it affects both the levels of performance expressed, and the relationship between performance and fitness. How does environmental variation within a generation determine natural selection on performance curves… CONTINUE READING
