Allelopathy of Bracken Fern (Pteridium arachnoideum): New Evidence from Green Fronds, Litter, and Soil [PDF]

open access: yesPLoS 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

Ptaquiloside and Pterosin B Levels in Mature Green Fronds and Sprouts of Pteridium arachnoideum. [PDF]

open access: yesToxins (Basel), 2020
Pteridium arachnoideum, a fern of the Pteridium aquilinum species complex found in South America, is responsible for several different syndromes of poisoning. Cases of bovine enzootic hematuria and upper alimentary squamous cell carcinoma are both frequent occurrences in Brazil, whereas only bovine enzootic hematuria is noted with any frequency around ...

The role of Pteridium arachnoideum(Kaulf) on the seed bank of the endangered Brazilian Cerrado [PDF]

open access: yesBrazilian Journal of Biology, 2016
Abstract The native bracken (Pteridium arachnoideum) often occurs in mono-specific stands in the Brazilian Cerrado, and this dominance can impact on both the above-ground vegetation and soil seed bank. This study investigated how invasion by this species over a 20-year period changed the seed bank and the relationship between the seed bank and litter ...

Cyanogenic polimorphysm in brackens, Pteridium arachnoideum and P. caudatum, from the northern Andes [PDF]

open access: yesQuimica 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 fern species the continuous distribution of prunasin suggested cyanogenic polymorphism.

Interference of Pteridium arachnoideum (Kaulf.) Maxon. (Dennstaedtiaceae) on the establishment of rainforest trees [PDF]

open access: yesBrazilian Journal of Biology, 2010
In order to identify the effect of P. arachnoideum, we studied 11 native tree species commonly used in reforestation projects. Bioassays were conducted in laboratory to evaluate the effect of bracken leachate on the germination and morphology of seedlings. Juveniles of some of these species were planted in two adjacent but contrasting areas in relation

Invasion impact by Pteridium arachnoideum (Kaulf.) Maxon (Dennstaedtiaceae) on a neotropical savanna [PDF]

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 ecological filters in the assembly of invaded communities. We investigated the effects of Pteridium

Temporal dynamics of the superdominant bracken fern Pteridium arachnoideum in Neotropical savanna-riparian forest transitions

open access: yesRodriguesia, 2023
Abstract Clonal growth can be especially advantageous in spatially heterogeneous environments and some clonal plants are highly invasive or superdominant, especially in disturbed environments. However, their temporal dynamics in the absence of large disturbances are not well known.

Worldwide relationships in the fern genus Pteridium (bracken) based on nuclear genome markers. [PDF]

open access: yesAm 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.
