Richard Southwood and Others Suggested Species Cannot Coexist If D/w

Question

Richard Southwood and others suggested species cannot coexist if d/w is A) <1 B) >1 C) >1<3 D) >3<1 E) >3

Accepted Answer

Species cannot coexist if their niche overlap (d) divided by the niche width (w) is less than 1 (d/w < 1), according to Richard Southwood's theory. This suggests that if the overlap is too great relative to the niche width, the species will compete too directly and cannot coexist.
