The purpose of the research is to study the most important stages within the regeneration cycle of the anemochorous tree species Aspidosperma tomentosum Mart. (AT), Qualea grandiflora (QG) Mart. and Vochysia tucanorum Mart. (VT) in the Mbaracayú Natural Forest Reserve located in eastern Paraguay. These are species typical of the cerrado biome. Study of their regeneration ecology is important as no such research has been carried out to date.CONACYT – Consejo Nacional de Ciencia y TecnologíaPROCIENCIA
