Cryptic colouration can be adjusted to the local environment by physiological (rapid) change, and/or by morphological (slow) change. The threat-sensitivity hypothesis predicts that the degree of cryps
Size imposes physiological and ecological constraints upon all organisms. Theory abounds on how energy flux covaries with body size, yet causal links are often elusive. As a more direct way to assess
Understanding the patterns of genetic variation and constraint for continuous reaction norms, growth trajectories, and other function-valued traits is challenging. We describe and illustrate a recent
