Última Key decision-making criteria for dormancy-breaking and ability to form seed banks of Cerrado native tree species Acta Botanica Colado,Maria Luciana Zequim; Reis,Letícia Koutchin; Guerra,Angélica; Ferreira,Bruno Henrique dos Santos; Fonseca,Diego Rezende; Timóteo,Amanda; Gondim,Evânia Xavier; Guerin,Natalia; Garcia,Letícia Couto. ABSTRACT Ecological restoration by direct seeding in the Cerrado biome still lacks information about native species germination, the need for dormancy overcoming and seed bank formation. This study aims to verify the effects of dormancy overcoming on germination of four tree species and the ability of 12 tree species to form seed banks for restoration use. Our results showed wide variation of species’ germination rates. Overcoming dormancy enhanced germination for Dimorphandra mollis, Hymenaea stigonocarpa, and Peltophorum dubium and decreased it for Copaifera langsdorffii, but was only cost-effective for H. stigonocarpa. Regarding the ability to form seed banks, only H. stigonocarpa and Cecropia pachystachya germinated and live seedlings of Terminalia...

Maxon (Dennstaedtiaceae) on a neotropical savanna Acta Botanica Guerin,Natalia; Durigan,Giselda. Whether management intervention is required to control biological invasions depends primarily on demonstrating species losses resulting from such invasions. Brackens of the Pteridium genus are currently regarded as a problem species that act as important ecological filters in the assembly of invaded communities. We investigated the effects of Pteridium arachnoideum invasion on the diversity, structure, floristic composition, and functional traits of cerradão in Assis, São Paulo, Brazil. We compared an invaded site with an adjacent non-invaded site. Bracken constrained the establishment of tree species, resulting in a community structure remarkably distinct from the non-invaded area. The density and basal area of the arboreal community were higher in...
