“…Aparisthmium/Alchornea and Poaceae undif. can occur in open areas such as canga and forest patches, in the transition between cangas and forests, and in forest interiors (Da-Costa et al, 2018; Viana et al, 2018). In addition, these plants are anemophilous, that is, they have pollination strategies and flower structures associated with high pollen productivity (Gosling et al, 2009).…”

However, most of these studies have prioritized trees and lianas (Souza et al 2014;Secco and Bigio 2017;Costa et al 2018;Secco et al 2019), and little attention has been given to herbaceous plants, even though they are common. Such conduct is also observed in other families in the mentioned bioma (Souza et al 2020).…”
