... predicted that the immune response to the KLH antigen would be suppressed to a greater extent in the animals characterised by the high BMR because of the elevated heat production rate, which would be increased further by the heat-generating humoral response. KLH challenge resulted in a transient...

... of the four immune measurements taken (complement-mediated lysis, humoral responses to tetanus and diphtheria toxoid). This difference is not likely to be explained by phylogeny because turnstone's closest relatives (sanderling, red knot and ruff) were as low responders as the more distantly related bar...
