ABSTRACT The two species of bracken fern, Pteridium esculentum and aquilinum , are well known to produce neoplastic lesions thiamine deficiency when consumed by mammals, with severe consequences health. New Zealand Pre‐European Māori have rhizomes P. as food little or no recorded Processing methods prior consumption may helped detoxify this food. We carried out LDH toxicity tests on that had be...

Jasmonate-mediated regulation of VOC emission has been extensively investigated in higher plants, however, only little is known about VOC production and its regulation in ferns. Here, we investigate whether the emission of VOCs from bracken fern Pteridium aquilinum is triggered by herbivory and if so - whether it is regulated by the octadecanoid signaling pathway. Interestingly, feeding of both...

Young leaves of Manihot esculenta Crantz (Euphorbiaceae), Abelmoschus esculentus (Malvaceae), Hibiscus acetosella (Malvaceae) and Pteridium aquilinum (Dennstaedtiaceae) are currently consumed as green vegetables by peoples in sub-Saharan Africa, Latin America, Asia and their migrants living in Western Europe. Sub-Saharan peoples use Manihot, Abelmoschus and Hibiscus also in the folk medicine to...

Abstract The native bracken fern ( Pteridium aquilinum (L.) Kuhn) has become increasingly invasive in abandoned or undergrazed Alpine grasslands. Bracken stands are generally assumed to be poor species, but there is still very little information about the impact on fauna. We recorded Orthoptera communities of 24 sample plots with varying cover. Compared only sparse medium cover, species richnes...

Bracken fern (Pteris aquilina) mixed with a grain mixture (1:3 by weight) was fed to a group of 40 female 6-week-old Swiss mice intermittently every other week for a total experimental period of 60 weeks. Thirty-three mice survived 30 or more weeks and all developed lymphatic leukemia with multiple organ involvement. Additionally, 5 mice developed multiple pulmonary tumors. No urinary bladder o...
