Competition coefficients: ?’s
?: Proportional constants relating the effect of one species on the growth of a 2nd species to the effect of the 2nd species on its own growth
?12 > 1 Impact of sp. 2 on sp. 1 greater than the impact of sp. 1 on itself
? 12 < 1 Impact of sp. 2 on sp. 1 less than the impact of sp. 1 on itself
? 12 = 1 Impact of sp. 2 on sp. 1 equals the impact of sp. 1 on itself
