This article adds new information about the proteome of tho relative ferns: Dryopteris affinis and D. oreades.
Article
Ferns are a diverse evolutionary lineage, sister to the seed plants, which is of great ecological importance and has a high biotechnological potential. Fern gametophytes represent one of the simplest autotrophic, multicellular plant forms and show several experimental advantages, including a simple and space-efficient in vitro culture system. Howev...
Article
Full-text available
The gametophyte of ferns reproduces either by sexual or asexual means. In the latter, apogamy represents a peculiar case of apomixis, in which an embryo is formed from somatic cells. A proteomic and physiological approach was applied to the apogamous fern Dryopteris affinis ssp. affinis and its sexual relative D. oreades . The proteomic analysis co...
Article
Phenotypic variation may be due to genetic and/or environmental causes. Many ecologists consider that phenotypic plasticity, which is the change in the phenotype expressed by a single genotype subjected to different environments, is an evolutionary strategy for adapting to variable environments. Also, it has been hypothesized that plasticity is hig...
Article
Habitat loss and fragmentation are the primary causes of global population decline of amphibians and reptiles. In Brazil, that hosts an extraordinary herpetofaunal richness, amphibians and reptiles are clearly undersampled among vertebrate groups in fragmentation research. This bias may underestimate the effects of fragmentation on herpetofauna in...
Article
Habitat loss and fragmentation are among the main threats to global biodiversity and ecosystem services. However, major research biases and knowledge shortfalls in some geographical regions, taxonomic groups and responses studied are recurrent in fragmentation-related research. Therefore, detecting these biases and associated gaps is crucial to ste...
Article
Full-text available
The thelypteroid fern genus Stegnogramma s.l. contains around 18–35 species and has a global, cross‐continental distribution ranging from tropical to temperate regions. Several genera and infrageneric sections have been recognized previously in Stegnogramma s.l., but their phylogenetic relationships are still unclear. In this study, we present a gl...
Article
Full-text available
Hybridization is a ubiquitous force in plant evolution. In ferns, hybrids are often easily recognized by their intermediate morphology and abortive spores and thus provide a good model for studying reproductive isolating barriers between species. Asplenium ×aran-tohanum is a rare fern hybrid, despite wide coexistence of its parental species (A. bil...
Article
Aim: To disentangle the influence of environmental factors at different spatial grains (regional and local) on fern and lycophyte species richness and ask how regional and plot-level richness are related to each other. Location: Global. Time period: Present. Major Taxa studied: Ferns and lycophytes. Methods: We explored fern and lycophyte species r...
Article
Premise: When two populations of related cytotypes grow in sympatry, the rarer cytotype tends to be excluded due to a frequency-dependent mating disadvantage. Evolutionary models predict that polyploids, which are typically the rarer cytotype upon first formation, should have higher relative fitness and/or higher selfing rates to establish and the...
Chapter
One of the main concerns of current environmental toxicology is the low number of taxa used for standard bioassays. Ferns are the second largest group of vascular plants and are important components of numerous plant communities. Fern spores and gametophytes have long been recognized as useful models for plant research, since they constitute a natu...
Article
Aims Plants control leaf phenology to maximize annual photosynthetic product. Although ferns play an important ecological role in many habitats, especially forests, their phenology traits have been poorly studied. Here, we investigate the leaf phenology of two ferns of the forest understorey and analyse the relationship between the timing of leaf e...
Article
Full-text available
Environmental sex determination is present in several animal and plant lineages. Diverse factors such as temperature, light or water availability have been described as sex determinants in these organisms. Among plants, ferns frequently display ESD. This work compares the effect of different levels of water availability in two diploid species of th...
Article
Full-text available
In environmental sex determination (ESD) gender is decided after conception, depending on the environment, rather than being genetically fixed. ESD has rarely been studied in homosporous ferns. In the present study, Culcita macrocarpa gametophytes were cultured under varying nutrient conditions. Initially, most of the gametophytes of Culcita macroc...

Article
Full-text available
A previous study detected no allozyme diversity in Iberian populations of the buckler-fern Dryopteris aemula. The use of a more sensitive marker, such as microsatellites, was thus needed to reveal the genetic diversity, breeding system and spatial genetic structure of this species in natural populations. Eight microsatellite loci for D. aemula were...
Article
Changes in forested landscapes may have important consequences for ecosystem services and biodi-versity conservation. In northern Spain, major changes in land use occurred during the second half of the 20th century, but their impacts on forests have not been quantified. We evaluated the dynamics of landscape and forest distribution patterns between...
Article
Full-text available
Studies on genetic diversity help us to unveil the evolutionary processes of species and populations and can explain several traits of diploid-polyploid complexes such as their distributions, their breeding systems, and the origin of polyploids. We examined the allozyme variation of Dryopteris aemula and D. oreades, diploid ferns with highly fragme...

This paper deals with the influence of altitude and canopy cover on spore maturation and release of Culcita macrocarpa and Woodwardia radicans in the island of São Miguel, Azores. The study was conducted during one sporing se...
Article
Full-text available
Ferns are an important component of many ecosystems and potentially provide an abundant food resource for consumers, but there are very few studies on the ecology of fern feeding by vertebrates. We describe the selection of sporangia and leaves among fern species by the Azores bullfinch (Pyrrhula murina), and addressed the importance of nutritional...

Article
Summary • In environmental sex determination (ESD) gender is decided after conception, depending on the environment, rather than being genetically fixed. ESD in plants has been mainly studied in angiosperms, where the dominant form of ESD is sexual lability. Surprisingly, ESD has rarely been studied in homosporous ferns, the only plants in which ES...
Article
Full-text available
Several models predict that the establishment of polyploids within diploid populations is enhanced by non-random mating (i.e. selfing and assortative mating) of cytotypes and by a higher relative fitness of polyploids. This report assesses the role that antheridiogens (i.e. maleness-inducing pheromones) and intercytotype differences in growth rate...
Article
Spore germination of Culcita macrocarpa C. Presl and Woodwardia radicans (L.) Sm. from nine populations at the northern limit of their distribution, in the northwest Iberian Peninsula, was investigated. In a first experiment, population type and temperature (10, 15, 20, and 25 °C) were both found to affect germination percentage and germination tim...

This study deals with the heliophilous shrub communities associated as prewoodland mantle communities with the wet temperate woodlands of South Central Chile. Previous studies have defined some communities proposed to belong to the order Aristotelietalia chilensis, subordinated to the principal class of the wet temperate woodlands of the Wintero-No...
Article
Full-text available
For many plants, sex is not fixed by genotype but determined by environmental conditions during development. In homosporous pteridophytes, sex is environmentally determined by the presence or absence of antheridiogens, maleness-inducing pheromones. It has been proposed that antheridiogens primarily reduce growth rate, with small gametophyte size re...
Article
Full-text available
Isozymes were used to study genetic variation in the clonal ferns Culcita macrocarpa and Woodwardia radicans in the northwestern Iberian Peninsula, their northern distributional limit. Despite their high chromosome numbers, both species were isozymic diploids. In C. macrocarpa all 18 resolved loci were monomorphic, with the same allele in all ramet...

Article
Full-text available
Although allopolyploidy is a prevalent speciation mechanism in plants, its adaptive consequences are poorly understood. In addition, the effects of allopolyploidy per se (i.e. hybridization and chromosome doubling) can be confounded with those of subsequent evolutionary divergence between allopolyploids and related diploids. This report assesses wh...
