A Phytosociological Study on Andean Rainforests of Peru, and a Comparison with the Surrounding Countries.

This work is a phytosociological approach to the montane rainforests of Peru with the aim of advancing on the diversity of plant communities, which we had already begun in previous research. From 364 phytosociological plots and 3389 species of the South American tropics, we have developed a cluster, using the Sørensen index, to know the similarities between the forests and their parallelism with bioclimatic conditions. After studying the existence of characteristic groups of the Peruvian forests, we have established different communities and phytosociological units for Peru.

[A phytosociological interpretation of vegetation from sandy hills of the Peruvian desert].

The vegetation of the sandy hills ("lomas") constitutes the main originality of the Peruvian and Chilean desert with a high number of endemics that shapes the vicarious associations. In this work, a phytosociological view of sandy environments of the Peruvian coastal desert is presented. According to the Braun-Blanquet method, we have made up 32 phytosociological inventories and added 138 ones from others authors.

A first survey on the medicinal plants of the Chazuta valley (Peruvian Amazon).

Aim Of The Study: At present, the Peruvian Amazonian district of Chazuta represents one of the main reservoirs of the San Martin Quechuas (also known as Lamas Quechuas) and their culture. These particular Quechuas, as well as the region of Chazuta, have been seldom studied from an academic point of view. With the objective of contributing to the ethnopharmacological knowledge of the area, a field survey on the use of medicinal plants was performed in the region.
