W.W. Wood, W. E. Sanford, S.K. Frape
2005, Chemical Geology (215) 361-372
Sabkha deposits in the geologic record are commonly used to interpret the environmental conditions of deposition. Implicit in this use is the assumption that the solute system is chemically closed, that is, the authigenic minerals represent the composition of the fluids in their environment of origin. Thermodynamic and mass-balance calculations...
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...
