Invasion Impact by Pteridium arachnoideum (Kaulf.) Maxon (Dennstaedtiaceae) on a Neotropical Savanna

open access: yesActa Botanica Brasilica, 2015
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

Proximity and abundance of mother trees affects recruitment patterns in a long‐term tropical forest restoration study

open access: yesEcography, Volume 44, Issue 12, Page 1826-1837, December 2021., 2021
Remnant trees and forest fragments in agricultural landscapes can be important sources of propagules to facilitate forest recovery. However, many studies simply quantify forest cover in the surrounding landscape as a percentage, with little attention given to species composition, and subsequently fail to detect an effect on recruitment patterns.
