Abstract Dispersal is a key process in plant population dynamics. In ferns, two successive vectors are needed: the sporangium catapulting mechanism, and wind or gravity. However, some rock ferns have a growth habit that suggests a kind of autochory by placing spores on the rock surface. Moreover, some ferns show modifications of the sporangial dehiscence. To determine the role of growth habit in spore dispersal, we checked the sporangial opening mechanism and explored the spatial distribution…

Fitness of an allopolyploid rupicolous fern compared with its diploid progenitors: from sporogenesis to sporophyte formation.
TLDR
The authors' results show no evidence of higher selfing or fitness advantage of the allopolyploid over both diploid parents at any stage of early recruitment, and patterns of sporophyte formation by females and bisexuals indicate that the polyploid does not have an increased gametophytic selfing rate.

Fern and bryophyte endozoochory by slugs
TLDR
New ecological perspectives are opened suggesting that fern and bryophyte endozoochory by gastropods is a so-far-overlooked mode of dispersal, which might increase local population sizes of these taxa by spore deposition on suitable substrates.
Sporangium Exposure and Spore Release in the Peruvian Maidenhair Fern (Adiantum peruvianum, Pteridaceae)
TLDR
This work investigated the different processes involved in spore liberation in the polypod fern Adiantum peruvianum (Pteridaceae), and found that the whole sporangium, or parts of it, together with contained spores break away from the false indusium and are shed as a whole.
Fern and lycopod spores rain in a cloud forest of Hidalgo, Mexico
TLDR
The aim of this study was to determine the composition of the “spore rain” of ferns and lycopods in a cloud forest and find the sporulation period for each species.
Is fern endozoochory widespread among fern-eating herbivores?
TLDR
The overall high germination success and the absence of differences among f Fern species from different habitats together with the consistency across three tested herbivores strongly imply endozoochorous dispersal to be a taxonomically widespread phenomenon among fern-eating herbivore species, which all might act as potential dispersal vectors.
Aerobiology of Pteridophyta Spores: Preliminary Results and Applications
TLDR
There are few studies reporting information about hourly distribution of fern spores in the atmosphere, in which bracken spores were mainly observed at midday when spore traps are located near to fern formations.
Spore Maturation and Release of Two Evergreen Macaronesian Ferns, Culcita macrocarpa and Woodwardia radicans, along an Altitudinal Gradient
TLDR
In both species spore maturation occurred in autumn and may be controlled by the previous accumulation of photosynthates, which is important for the endemic Azores bullfinch Pyrrhula murina, providing food over an extended period.
Indehiscent sporangia enable the accumulation of local fern diversity at the Qinghai-Tibetan Plateau
TLDR
The presented results confirmed the hypothesis that indehiscent sporangia promote the establishment of persistent population in different regions of the QTP and are consistent with the expectations of reproductive reassurance by promotion of self-fertilization that played a critical role in the assembly of populations in isolated locations and/or extreme habitats.
Homospory 2002: An Odyssey of Progress in Pteridophyte Genetics and Evolutionary Biology
TLDR
This review will consider how new discoveries, insights, and hypotheses have modified the authors' perceptions of homosporous pteridophytes and assess the impact that these changes have had on understanding basic aspects of plant genetics.
AN EXAMPLE OF SPORANGIAL INDEHISCENCE IN THE FILICOPSIDA

    Evolution; international journal of organic evolution
  • 1977
TLDR
Investigation of plants raised in cultivation from spores collected in the wild has shown that there is considerable morphological variation between populations and that each one can be readily distinguished by its characteristic and consistent combination of frond morphology and growth form.
On the widespread capacity for, and functional significance of, extreme inbreeding in ferns.
TLDR
Evidence is presented from the largest study of mating behavior in ferns to date that the capacity for extreme inbreeding is prevalent in this lineage, and its implications and relevance are discussed and recommendations are made for future studies of fern mating systems.
