Soil biotic and abiotic conditions negate invasive species performance in native habitat
Abstract Background Most studies on plant invasion consider the enemy release hypothesis when analyzing native habitats. However, the lower performance of invasive species in the native habitats can be the result of unfavorable soil conditions in the native habitats. While soil biotic and abiotic fa...
