From: Strigea robusta causes polydactyly and severe forms of Rostand’s anomaly P in water frogs
Survivorship, frequency and complexity of the anomaly P in Pelophylax lessonae tadpoles infected with Strigea robusta. a Frequency of mild and severe forms of anomaly P in tadpoles under a given treatment (infection with 0, 16, 32 and 48 cercariae). Initial sample sizes in each treatment were 20 tadpoles. b, c Complexity of anomalies in tadpoles on “late” (b) and “early” (c) stages of limb development. Initial sample sizes in each group were 10 tadpoles. d Correlation between survivorship and frequency of anomalies in tadpoles
