Urochloa mutica

Em estudo de regeneração natural em área de mineração abandonada, os autores encontraram que maiores coberturas de U. mutica estão correlacionadas com a menor cobertura de espécies nativas (Bayliss et al. 2006).

Extrato aquoso de folhas de U. mutica inibe o desenvolvimento de raízes de L. sativa em experimentos de laboratório (Chou & Young 1975).

In the dry season, there was evidence of adverse effects of para grass invasion on terrestrial invertebrates, but only compared with hymenachne. Mean richness and abundance in para grass were both lower than in hymenachne. This is due to the higher moisture content of hymenachne. In the wet season, there was evidence that para grass invasion would lead to reduced invertebrate biodiversity and abundance relative to Hymenachne, but not compared with wild rice. Para grass invasion will have variable impacts on terrestrial invertebrate richness and abundance depending on the grass communities that it displaces. While there may be no detectable changes where para grass displaces wild rice, where it displaces hymenachne, the changes will be great and this will likely have implications for other floodplain fauna (Douglas & Connor, 2004)
