Biodiversity loss decreases parasite diversity: theory and patterns
Kevin D. Lafferty
2012, Philosophical Transactions of the Royal Society B: Biological Sciences (367) 2814-2827
Past models have suggested host–parasite coextinction could lead to linear, or concave down relationships between free-living species richness and parasite richness. I explored several models for the relationship between parasite richness and biodiversity loss. Life cycle complexity, low generality of parasites and sensitivity of hosts reduced the robustness of parasite...
