Twо plаnt species exist in rаnges mоstly in isоlаtion from one another but the two overlap in a narrow band where their ranges meet. A researcher does a controlled experiment in a common habitat to determine the effect of each species on the other's fitness, by creating replicate combinations of the speces (A only, A+B, B only). Assume that the average differences in the table are statistically significant. Species Species present in these locations Average seeds/individual/year A A only 540 A Both A and B 560 B B only 232 B Both A and B 210 Which one of the following statements appears to be true? Choose all correct answers.
