Journal Article
Composition and cytotoxic activity of essential oils from Croton matourensis and Croton micans from Venezuela.
TL;DR: The cytoxicity of these oils was screened by the MTT method against three human tumour cell lines and primary culture of human dermis fibroblasts (normal control cells) and indicate that the oils have a moderate cytotoxicity against LoVo, X-17, HeLa, and control cells.
Journal ArticleDOI
Inventory of related wild species of priority crops in Venezuela
TL;DR: The inventory of wild and naturalized relatives of priority crops in Venezuela (CWR) is based on the main Catalogues of Flora in the country, selecting taxa closely related to crops, according to the concepts of “gene pool” and “taxonomic group”.
Journal ArticleDOI
Novelties in Selaginella (Selaginellaceae - Lycopodiophyta), with emphasis on Brazilian species.
TL;DR: Five new species of Selaginella from Brazil are described, compared to morphologically similar species, and a preliminary conservation status assessment for each is provided, and leaf marginal stomata are reported on the newly described species.
Journal ArticleDOI
Spatial relations and population structure of a dominant tree along a treeline ecotone in the Tropical Andes: interactions at gradient and plant-neighbourhood scales
TL;DR: In this article, the authors analyzed the population structure and local spatial relationships of a dominant tree at a species-rich tropical Andean forest line and found that saplings showed local spatial aggregation, were positively associated with small boulders and low shrubs, and negatively associated with mosses and lichens.
