Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstracts

The work conelete of a survey of the mvaewe plants which appeared during the first six months of seedling stage in foreet plantations of second and third rotation, in the Jari area, Brazil. The resulting list showed two types of invasives: (1) true weeds - those cosmopolitan species that are typical of disturbed habitats; and (2) pioneer species - those which were probably remnants from the original natural vegetation of the studied area.
