Amongst-host distributions of metazoan parasites in Apodemus sylvaticus ( N = 100) at Cotgrave Forest, UK (+52.891, -1.041242) July–November 2007. A) Box plots of log-transformed individual counts for endoparasitic helminths occurring in the gut (Syphacia stroma, Heligmosomoides polygyrus, Brachylaemus recurvum, Skrjabinotaenia lobata, Aoncotheca annulosa, Heterakis spumosa). For S. stroma, results are presented for all stages and for gravid females alone. Percentage prevalence is given below each box plot. B) Pie chart representing proportional distribution of the A. sylvaticus sample amongst infection grades for the hepatozoic nematode Calodium hepaticum (see Methods). C) Box plots of log-transformed individual counts for laelapid mites, ticks (Ixodes trianguliceps) and fleas (Ctenophthalmus nobilis) occurring on the body surface. Percentage prevalence is given below each box plot. D-E) Pie charts representing proportional distribution of the A. sylvaticus sample amongst infection grades for lice (Polyplax serrata) (D) and trombiculid mites (E) (see Methods). Box plots show the individual scatter of data, the median (line), the interquartile range (box) and the range between the highest and lowest values (whiskers) excluding outliers (values differing by more than 1.5 times the interquartile range interval from the nearest limit of the interquartile range). The pie charts show increasing infection grade clockwise.
