We present information on the distribution of the endemic Bolivian primates Callicebus olallae and C. modestus based on a series of site visits in the Beni Department. Callicebus olallae was registered at four localities and C. modestus at 11 localities, and in combination with negative data and localities for other Callicebus species in the region we defined the distributional boundaries for b...

Substituted aromatic amines were diazotized followed by coupling with malononitrile to afford substituted phenyl hydrazono-malononitrile compounds 2a-c. Compounds 3a-c were prepared through the reaction of substituted phenyl hydrazono-malononitriles 2a-c with phenyl hydrazine, while the reaction of compounds 2a-c with hydrazine hydrate afforded diamino compounds 4a-c. The diamino compounds 4a-c...

BACKGROUND That the answers elicited through interviews may be influenced by the knowledge of the interviewer is accepted across disciplines. However, in ethnobotany, there is little evidence to quantitatively assess what impact this effect may have. We use the results of a large study of traditional ecological knowledge (TEK) of plant use of the Chácobo and Pacahuara of Beni, Bolivia, to explo...
