Long‐term subtropical grassland plots take a long time to change: Replacement is more important than richness differences for beta diversity

Ecology and Evolution, Volume 13, Issue 6, June 2023., 2023
We studied β diversity of grasses in a subtropical grassland over 60 years with different burning and mowing frequencies. Changes in grassland composition took a long time to manifest themselves. We found that summer mowing was the primary driver and that there was a significant interaction effect between mowing and soil depth.
