Imagine Community 1: 5 species, one dominant species (e.g., 70 individuals), others rare (e.g., 5-10 each). Community 2: 5 species, each with roughly equal abundance (e.g., 20 individuals each).

A key exception to the Species-Productivity Hypothesis is:

After a volcanic eruption, the colonization of the area that was covered by the lava from the eruption is best described as:

What concepts enable two or more species with similar niches to coexist in a community? Select all that apply.
