摘要
A traditional way to measure them is to use pairwise experiments, but such experiments do not scale up to 物種‐rich communities. For those, using association 網絡s based on spatial patterns may provide a more realistic approach. While this method has been successful in abiotically‐stressed environments (alpine and arid ecosystems), it is unclear how well it generalizes to other types of environments. We help fill this knowledge gap by documenting how the structure of plant communities changes in a Mediterranean dry grassland grazed by sheep using plant spatial association 網絡s. We investigated how the structure of these 網絡s changed with grazing intensity to show the effect of biotic dist城市ce on community structure. We found that these grazed grassland communities were mostly dominated by negati
