“magnitude of decrease”

Claim · model-written summary

The magnitude of the landscape-scale decrease was best explained by the number of plots where an alien species was above its critical abundance.

“declines in native γ ‐richness were, on average, an order of magnitude (32.0 vs. 2.2 species) greater”

Claim · model-written summary
