The study looked at how different plants grow in a sandy area with varying levels of acidity and height. They found that the most plant species were in the middle of the gradient. The plants were grouped based on how much information they shared, and they found that the acidity of the soil was the main factor affecting the plants. The researchers also found that the plants were different from each other based on where they were along the gradient. This shows that plants adapt to their environment by finding different niches to grow in.
