Phylogenetic analysis of amplified fragment length polymorphisms (AFLP) was used to infer patterns of morphologic and chromosomal evolution in an eastern North American group of sedges (ENA clade I of Carex sect. Ovales). Distance analyses of AFLP data recover a tree that is topologically congruent with previous phylogenetic estimates based on nuclear ribosomal DNA (nrDNA) sequences and provide...

The importance of competition in determining species coexistence has been much debated. A phylogenetic analysis of sedges indicates that competitive exclusion may inhibit co-occurrence among closely related species, but not among more distant relatives.
Sida acuta is a shrub indigenous to pantropical regions. The plant is widely used for its various pharmacological properties. Among compounds of pharmacological interest occurring in the plant, are indoloquinoline alkaloids. The aim of the present study was to investigate the antimicrobial activity of alkaloids of S. acuta from Burkina Faso. The alkaloids had a good antimicrobial activity again...
