Molecular phylogeny and diversification history of Prosopis (Fabaceae: Mimosoideae)
The genus Prosopis is an important member of arid and semiarid environments around the world. To study Prosopis diversification and evolution, a combined approach including molecular phylogeny,… Expand
Molecular Ecology Resources Primer Development Consortium
Biodiversity characterization of cellulolytic bacteria present on native Chaco soil by comparison of ribosomal RNA genes.
Sequence analysis of the 16S ribosomal RNA gene was used to study bacterial diversity of a pristine forest soil and of two cultures of the same soil enriched with cellulolytic bacteria. Our analysis… Expand

Distribution of chromosome frequencies within a hybrid zone of Dichroplus pratensis (Melanoplinae, Acrididae)
The widespread South American melanopline grasshopper Dichroplus pratensis is chromosomally polytypic. Seven different Robertsonian translocations between six L-autosomal pairs of the standard… Expand
Suitability of AFLP markers for the study of genomic relationships within theOxalis tuberosa alliance
O. tuberosa is an Andean crop that belongs to the worldwide distributed genusOxalis. On the basis of their chromosome numbers the following species (O. herrerae, O. lotoides, O. medicaginea, O.… Expand
Phylogenetic relationships of Deschampsia antarctica (Poaceae): Insights from nuclear ribosomal ITS
Deschampsia antarctica E. Desv. is the only monocot in the Antarctic floristic zone. We evaluated the phylogenetic relationships of Deschampsia antarctica to other grasses using parsimony as the… Expand
Sequence analysis of the 5.8S ribosomal DNA and internal transcribed spacers (ITS1 and ITS2) from five species of the Oxalis tuberosa alliance.
The internal transcribed spacer region (ITS1 and ITS2) of the 18S-25S nuclear ribosomal DNA sequence and the intervening 5.8S region from five species of the genus Oxalis was amplified by polymerase… Expand
The key role of the largest extant Neotropical frugivore (Tapirus terrestris) in promoting admixture of plant genotypes across the landscape
The historical and contemporary loss of large-bodied frugivores has disrupted many plant-disperser mutualisms, with potentially profound consequences for plants. Although several aspects of seed… Expand
Phylogenetic relationships among southern South American species of Camptosema, Galactia and Collaea (Diocleinae: Papilionoideae: Leguminosae) on the basis of molecular and morphological data
The neotropical genus Camptosema in its southern distribution is represented by the following four species: Ca. paraguariense, Ca. praeandinum, Ca. rubicundum and Ca. scarlatinum. Ca. rubicundum is… Expand
