Host diversity begets parasite diversity: Bird final hosts and trematodes in snail intermediate hosts
R. F. Hechinger, K. D. Lafferty
2005, Proceedings of the Royal Society B: Biological Sciences (272) 1059-1066
An unappreciated facet of biodiversity is that rich communities and high abundance may foster parasitism. For parasites that sequentially use different host species throughout complex life cycles, parasite diversity and abundance in 'downstream' hosts should logically increase with the diversity and abundance of 'upstream' hosts (which carry the preceding stages...
