Abstract EN
Spartina alterniflora Loisel.
is one of the most invasive species in the world.
However, little is known about the role of artificial mowing in its invasiveness and competiveness.
In this work, we studied the effect of mowing on its interspecific interactions with native species Phragmites australis (Cav.) Trin ex Steud of the Yangtze Estuary, China.
We calculated their relative neighbor effect (RNE) index, effect of relative crowding (Dr) index, and interaction strength (I) index.
The results showed that the RNE of Phragmites australis and Spartina alterniflora was 0.354 and 0.619, respectively, and they have competitive interactions.
The mowing treatments can significantly influence the RNE of Phragmites australis and Spartina alterniflora on each other.
Concretely, the RNE of Spartina alterniflora in the removal treatments was significantly higher than the value in the controls.
But the RNE of Phragmites australis in the removal treatments was significantly lower than the value in the controls.
Meanwhile, Dr of the two species on the targets was higher in the removal treatments than that in the controls, and the opposite was for I.
We concluded that artificial mowing could promote the invasion of Spartina alterniflora by increasing its competitive performance compared with native species.
