Ecological opportunity and adaptive radiations reveal eco-evolutionary perspectives on community structure in competitive communities

Abstract It is well known that ecological and evolutionary processes act in concert while shaping biological communities. Diversification can, for example, arise through ecological opportunity and adaptive radiations and competition play an essential role in such diversification. Eco-evolutionary co...
