Infectious personalities: behavioural syndromes and disease risk in larval amphibians.

Behavioural consistency or predictability through time and/or different contexts ('syndromes' or 'personality types') is likely to have substantial influence on animal life histories and fitness. Consequently, there is much interest in the forces driving and maintaining various syndromes. Individual host behaviours have been associated with susceptibility to parasitism, yet the role of pre-existing personality types in acquiring infections has not been investigated experimentally.
