Figure 3From: Larval size in acanthocephalan parasites: Influence of intraspecific competition and effects on intermediate host behavioural changesProbability of reaching high phototaxis scores in gammarids (≥ 6) according to mean cystacanth volume. (a) Hosts infected by one cystacanth. (b) Hosts harbouring two cystacanths. (c) Hosts infected by more than two cystacanths. Diamonds are real data, curves are those calculated by the logistic regression model.Back to article page
