Several techniques are available for quantifying the vertebrate immune response, information that is particularly useful for understanding the contribution of immunity to the evolution of life-history strategies. The most widely used is the phytohaemagglutinin (PHA) skin-swelling technique, which is usually regarded as an index of acquired immunity. However, our understanding of the effects of PHA in skin is poor, despite the fact that it has implications for what the test can tell us about… CONTINUE READING
