autoecism

noun

1. (uncountable)The fact of a parasite or dependent organism completing an entire life cycle on a single host species.

   “Other measures[…]are deficient because of the large geographic distribution of the pathogens, their wide host ranges, their high spore dispersal capabilities, and the autoecism of some rusts.”

2. (uncountable)The fact of having male and female reproductive organs on the same individual plant.

   “Along with this view of pleomorphism, goes the generally conceived idea that autoecism is the primitive condition, heteroecism being considered a later adaptation (Klebahn, 1904).”
