A novel approach for the metric analysis of fern fronds: Growth and architecture of the Mesozoic fern Weichselia reticulata in the light of modern ferns. [PDF]
The architecture of primary and secondary pinnae of the fossil fern Weichselia reticulata (C. Stokes et Webb) Fontaine is studied based on 28 large specimens from the upper Barremian La Huérguina Formation of the fossil locality Las Hoyas, Cuenca, Spain.

Slowly but surely: gradual diversification and phenotypic evolution in the hyper-diverse tree fern family Cyatheaceae. [PDF]
Background and Aims The tremendously unbalanced distribution of species richness across clades in the tree of life is often interpreted as the result of variation in the rates of diversification, which may themselves respond to trait evolution.

Non-chlorophyllous and crypto-chlorophyllous fern spores differ in their mobilisation of fatty acids during priming. [PDF]
Abstract During fern spore germination, lipid hydrolysis primarily provides the energy to activate their metabolism. In this research, fatty acids (linoleic, oleic, palmitic and stearic) were quantified in the spores exposed or not to priming (hydration–dehydration treatments).

Propagación de dos helechos arborescentes (Cyatheaceae) del bosque nuboso guatemalteco por medio de tres metodologías diferentes [PDF]
Los helechos arborescentes de la familia Cyatheaceae están en especial peligro. Son organismos de crecimiento lento, y su extracción de los bosques originarios para el uso como sustituto de sustrato para bromelias y orquídeas ha colocado en riesgo las ...

Providing the missing links in fern life history: Insights from a phenological survey of the gametophyte stage. [PDF]
Abstract Premise The entire life cycle of ferns has been documented, yet their life histories are still poorly understood. In particular, the phenology of fern gametophytes remains largely unknown. To address this issue, we demonstrated a new ecological approach to explore the phenological link between spore release and gametophyte maturation within ...

Effective dispersal of fern spore and the ecological relevance of zoochory. [PDF]
ABSTRACT The mechanisms of fern dispersal are under‐studied and there are few data to support the vectors assumed to drive patterns of sporophyte occurrence and speciation. Although wind is generally the fern spore dispersal vector described in the literature, there has always been competing evidence supporting alternate vectors.

A dormant resource for genome size estimation in ferns: C-value inference of the Ophioglossaceae using herbarium specimen spores. [PDF]
Abstract Premise The great variation of genome size (C‐value) across land plants is linked to various adaptative features. Flow cytometry (FCM), the standard approach to estimating C‐values, relies mostly on fresh materials, performing poorly when used with herbarium materials. No fern C‐value reports have been derived from herbarium specimens; however,

Assessing the invasion risk of traded alien ferns using species distribution models [PDF]
Risk analysis plays a crucial role in regulating and managing alien and invasive species but can be time-consuming and costly. Alternatively, combining invasion and impact history with species distribution models offers a cost-effective and time ...
