Acúmulo de biomassa aérea e concentração de nutrientes em Melinis minutiflora P. Beauv. e gramíneas nativas do cerrado [PDF]

Revista Brasileira de Botânica, 2007
The African grass, Melinis minutiflora P. Beauv., is causing concern in Brazil since it is replacing native grasses in the cerrado region, even in protected areas. In the present study the accumulation of aerial biomass and concentration of nutrients in M. minutiflora and native grass species were compared to determine whether M.

Diurnal variations of non-structural carbohydrates in vegetative tissues of Melinis minutiflora, Echinolaena inflexa and Lolium multiflorum (Poaceae) [PDF]

Revista Brasileira de Botânica, 2005
Echinolaena inflexa (Poir.) Chase is a native C3 grass species with high biomass production and abundance in the cerrado comparable to Melinis minutiflora Beauv., a C4 forage grass of African origin, widespread in the cerrado, displacing some native herbaceous species. These species accumulate mainly starch, differently of Lolium multiflorum Lam.

Invasive-dominated grasslands in Hawai'i are resilient to disturbance. [PDF]

Ecol Evol
We ask whether most species in disturbed habitats fall into similar categories with respect to being strong competitors versus colonizers using a conceptual framework based on how species assemble into plots over time. Our study uses a replicated disturbance experiment, coupled with close tracking of plant cover and native seedlings, as well as a ...

Interception of water by pastures of Pennisetum clandestinum Hochst. ex Chiov. and Melinis minutiflora Beauv. [PDF]

Agricultural and Forest Meteorology, 2009
Abstract The conversion of montane cloud forests into pastures for grazing cattle is the main cause of important impacts on rivers and streams in most of the Andes. In order to evaluate the effects of vegetation changes we need to understand water fluxes, particularly canopy interception.
