Phylogenetic analysis of the Briza Complex (Poaceae).
A phylogenetic analysis of the Briza Complex was carried out using three DNA regions, and Briza sensu lato is not supported in most trees, and the American genera cannot be split due to unresolved polytomies. Expand
A Preliminary Approach to the Phylogeny of the Genus Paspalum (Poaceae)
The phylogenetic relationships among the species of Paspalum L. belonging to the informal groups Notata/Linearia and Dilatata are clarified, and some preliminary hypotheses on the phylogeny of the genus as a whole are raised. Expand
Assessing the genetic diversity and population structure of the endangered Chascolytrum bulbosum (Poaceae, Poeae) using AFLP markers
As gene flow occurs broadly through the geographical range of species found in Rio Grande do Sul, it is suggested the stimulation of in situ rather than ex situ conservation, and priority populations for conservation of C. bulbosum are indicated. Expand
Phenology and dry mass production of Urochloa plantaginea and Urochloa platyphylla submitted to different water quantities in the soil
The main responses observed for both species, due to the flooding, were the change of the cycle, reduced dry matter production, and reduced seed production. Expand
Phylogeny of Linearia and Notata groups of Paspalum L. (Poaceae, Panicoideae, Paniceae) and related species
This work uses a phylogenetic approach to study informal groups of Paspalum, using DNA sequences from ITS of nuclear rRNA, from chloroplast intergenic spacer psbA-trnH andchloroplast trnL intron to perform the analyses. Expand
Advances in the phylogeny of the South American cool-season grass genus Chascolytrum (Poaceae, Pooideae): a new infrageneric classification
The use of single-copy nuclear genes and morphological data for future phylogenetic reconstructions encompassing Chascolytrum is highlighted and the new infrageneric classification proposed for the group under the genus Briza is discussed. Expand
Three New Taxa of Chascolytrum (Poaceae, Pooideae, Poeae) from South America
Two new species and one new variety of Chascolytrum Desv. Expand
A checklist of Asteraceae from Pedra do Lagarto, Santa Maria, Rio Grande do Sul, Brazil

Solid waste management in southern Brazil
A large amount of solid waste generated by the population leads to social, environmental and health problems, so it is important that the Brazilian municipalities have programs for solid wasteExpand
Majoritary triterpenic compounds in some angiosperms of the central region of Rio Grande do Sul state
Five species of angiosperms collected in the Central Region of Rio Grande do Sul was evaluated due to their pharmacological properties. The objective of this study was to extract and characterize theExpand
