Refers to mimicry where both of the individuals are poisonous in some way. Holds its environment / ecology together (is necessary) Ex: productivity in the sockeye salmon: without them in their habitats, the community would suffer dramatically. Ex: prairie dogs in grasslands keystone herbivores. Ex: keystone predators wolves and starfish: slide 19 with the starfish, even its prey are able to thrive in the particular environment, wolves have changed river banks (the geography of land) Clements - interactive hypothesis: community is an (slide 24)
