Fig. 1. Necropsy of Turdus merula, female. Gross lesions are represented by heavy parasite colonization of coelomic cavity. A. Many trematodes are clearly seen on different serosal membranes. Note the presence of parasites on the liver serosa, air sacs and pericardium (arrow). B. After removal of all the organs of the gastroenteric apparatus, an involvement of kidney and lungs serosa is also evident. Note the presence of an inflammatory focus with exudate at the periphery of the left lung (arrowhead).

Fig. 3 in Environmental and ecological factors driving trematode parasite community assembly in central Alberta lakes

Fig. 3. Canonical correspondence analysis (CCA) of trematode component communities. Relative abundances of trematode species by sample are constrained by environmental variables from the best-fit model (community \lake trophic status \+ ecoregion \+ latitude). Trematode species abbreviations are shown in grey. CCA results are in red as eigenvectors. Ecoregions are identified with a blue dotted line. The trophic status of each lake is identified with an ellipse.
