During a study on desert plants the scientist had 2 identical plots with annual wildflowers in both plots. One plot was enclosed to keep out herbivores such as the kangaroo rat. After 2 years 4 of the wildflower species disappeared and 1 species of wildflowers increase significantly. The unprotected plot did not change. What would be the reasons for this?© BrainMass Inc. brainmass.com October 9, 2019, 9:04 pm ad1c9bdddf
My first comment would be that this experiment does not answer the question of why the species disappeared from the protected plot, all the experiment shows is that this did happen. So any answer to this question ...
The expert examines the identical plots with annual wildflowers in both plots.
