Spatial seed and pollen games: dispersal, sex allocation, and the evolution of dioecy.

Complex life cycles using three host species, free-living stages, asexual and sexual reproduction are widespread in parasitic helminths. For such life cycles, we propose here that maintaining a second intermediate host in ...
