This data shows that aspen in riparian areas (along streams) are larger than those in the uplands, suggesting that there is less browsing along streams. The reason for this could be tha ...

This, over time, changes to communities with a large number of more complex species. There are the following three stages in ecological succession: 1. Pioneer species stage The bare grou ...
