Think about your lawn (or your neighbors). You may mow, weed, fertilize, pesticide the place to achieve the model Scott’s monoculture, but as soon as you stop, this even, level, uniform space quickly grows in “weed” diversity. If a niche is a special place (like a south-facing, dry, rocky slope), then why do many species move in to occupy this uniform space?
What is an ecological niche in this context? What would the lawn look like in 5 years, and how would you describe and explain its structure? What might trouble you in thinking about niche differentiation and community structure in this lawn?
