The phenotypically variable bracken fern, Pteridium aquilinum (L.) Kuhn, is an economically important plant that establishes dense monocultural stands by spore dispersal and by spreading subterranean rhizomes throughout the world, except for hot and cold desert regions (Page, 1976). Bracken produces a number of so-called "secondary plant compounds" that have been shown to protect it from some nonadapted insects (Cooper-Driver et. al., 1977). These compounds include the cyanogenic glucoside… 
Evidence is provided that, in fact, bracken supports a large number of pathogens and herbivores and synthesizes a wide variety of secondary metabolites, which act as toxins and deterrents to these natural enemies.
Strategies for the protection of shoot buds in phanerophyte and geophyte species of Homalolepis Turcz. (Simaroubaceae, Sapindales)
Several structural attributes associated with the buds of shoot apices of angiosperms have been related to protection both at the mechanical and chemical defense levels. Although several
Ants impact sawfly oviposition on bracken fern in southern California
Bracken fern may derive a fitness benefit from attracting ants during the early phases of plant growth, through decreased herbivore oviposition, rather than through the deterrence of feeding larvae.

Analysis of the Caddisflies (Trichoptera) of the Manistee River Watershed, Michigan
We document 134 caddisfly species and their seasonal and habitat affinities based on 93 samples collected from 26 sites throughout the Manistee River watershed in the lower peninsula of Michigan from

An origin of Temnothorax at the Eocene-Oligocene transition, concerted transitions to arboreal nesting habits in several clades during the Oligocene, coinciding with ancient global cooling, and several convergent origins of social parasitism in the Miocene and Pliocene are suggested.
Insect Herbivores of Ferns along the Pacific Northwest Coast of North American
Results indicate that the insect clades belonging to the most ancient families, such as Aneugmenuss and Strongylogaster in the Tenthredinidae and Dasineura and Mycodiplosis in the Cecidiomyiidae, appear to be monophagous on ferns.
Cyanogenesis, herbivory and plant defense in Turnera ulmifolia on Jamaica
Field surveys of eight populations of Turnera ulmifolia L., a Jamaican weed exhibiting quantitative genetic variation for cyanogenesis, were undertaken to assess the effectiveness of cyanogenesis a...


The taxonomy and phytogeography of bracken—a review
  • C. Page
  • Environmental Science, Geography
  • 1976
Its palaeobiological spread, with associated vegetational history, and the effects on this of anthropogenic influences—better known than are comparable details for any other pteridophyte—are detailed, andThe present magnitude of the resulting bracken problem in Britain is indicated.
Cyanogenic polymorphism in bracken in relation to herbivore predation
It is found that cyanogenesis is also polymorphic in bracken, like in ferns and rhizome system, which deter predators and phytopathogens in these two species.
Bracken thiaminase‐mediated neurotoxic syndromes
Using a radiochemical assay, the distribution of thiaminase I activity in bracken throughout the growing season has been ascertained: levels are high in the rhizome and young buds, but fall sharply in the fronds as the aerial parts of the plant unfold.
