[Show abstract][Hide abstract] ABSTRACT: The village of La Morada on the northeastern slopes of the Andes, Peru, is a typical example of a recent settlement founded in the Ceja de Selva Alta by families of indigenous and mestizo descent, who originally came from the highlands. They have accumulated experiences of the impact of their resource-management practices, but with heavy emphasis on their highland background. Tremendous changes in the environment have been catalyzed by road construction, introduction of new settlements, crops, and most of all by the introduction of large numbers of cattle.

[Show abstract][Hide abstract] ABSTRACT: The present work represents an updated list of the Monocots (Liliopsida) present in the Venezuelan paramos. This catalog includes 17 families, 123 genera and 520 native species present in this ecosystem in Venezuela. Top monocot families at the species level in the paramos are Orchidaceae with 200, Poaceae with 179, Bromeliaceae with 42 and Cyperaceae with 39 species each one. It was found that of 520 native species, 68 are endemic to Venezuela, and in some cases to adjacent Colombian Andes, and from these 68 species, 58 endemic species belong to four families (Bromeliaceae, Orchidaceae, Poaceae and Cyperaceae). A characterization of the lower limit of the Venezuelan paramos based on the main genera of flowering plants present in the catalog (parts I y II) is also proposed.
