Allelopathy of Bracken Fern (Pteridium arachnoideum): New Evidence from Green Fronds, Litter, and Soil [PDF]
PLoS ONE, 2016 The neotropical bracken fern Pteridium arachnoideum (Kaulf.) Maxon. (Dennstaedtiaceae) is described as an aggressive pioneer plant species. It invades abandoned or newly burned areas and represents a management challenge at these invaded sites. Native to

Worldwide relationships in the fern genus Pteridium (bracken) based on nuclear genome markers. [PDF]
Am J Bot, 2019 Premise Spore‐bearing plants are capable of dispersing very long distances. However, it is not known if gene flow can prevent genetic divergence in widely distributed taxa. Here we address this issue, and examine systematic relationships at a global geographic scale for the fern genus Pteridium.

Cyanogenic polimorphysm in brackens, Pteridium arachnoideum and P. caudatum, from the northern Andes
Quimica Nova, 2010 Cyanogenesis in Pteridium caudatum and P. arachnoideum has been examined. Samples of the Andes of South America furnished from 0 to 4.63 mg of prunasin g-1 of frond dry weight (dw) in P. caudatum and from 0 to 103 mg of g-1 dw in P. arachnoideum. In both

Who will win where and why? An ecophysiological dissection of the competition between a tropical pasture grass and the invasive weed Bracken over an elevation range of 1000 m in the tropical Andes. [PDF]
PLoS ONE, 2018 In tropical agriculture, the vigorously growing Bracken fern causes severe problems by invading pastures and out-competing the common pasture grasses. Due to infestation by that weed, pastures are abandoned after a few years, and as a fatal consequence ...
