Abstract We present a family–level classification for the eupolypod II clade of leptosporangiate ferns, one two major lineages within Eupolypods, and few parts fern tree life where relationships were not well understood at time publication 2006 by Smith & al. Comprising over 2500 species, composition particularly among clades this group have historically been contentious defied phylogenetic resolution until very recently. Our reflects most current available data, largely derived from...
Abstract Aim It is well known that the distribution of species diversity spatially heterogeneous, but understanding factors contributing to this heterogeneity and formation biodiversity hotspots remains a challenge. Here, we seek improve our how historical, ecological evolutionary processes contribute current patterns global fern diversity. Location Worldwide. Taxon Ferns. Methods To evaluate drivers diversity, integrate over 800,000 georeferenced occurrence records nearly 8000 species,...
Abstract Aim Gondwanan vicariance, boreotropical migration and long‐distance dispersal have been posited as alternative hypotheses explaining the tropical distribution patterns diversifications in many fern groups. Here, historical biogeography of Diplazium is reconstructed to evaluate impact these biogeographical processes shaping modern disjunctions. Location World‐wide with a focus on forest habitats. Methods Divergence times were estimated by analysing nucleotide sequences seven plastid...
Patterns of morphological evolution at levels above family rank remain underexplored in the ferns. The present study seeks to address this gap through analysis 79 characters for 81 taxa, including representatives all ten families eupolypod II Recent molecular phylogenetic studies demonstrate that large clade (which includes nearly one-third extant fern species) features unexpected patterns. traditional 'athyrioid' ferns are scattered across phylogeny despite their apparent cohesiveness, and...

• Premise of the study: As currently circumscribed, Lastreopsis has about 45 species and occurs in Australia, southern Asia, Africa, Madagascar, neotropics. Previous molecular phylogenetic studies suggested that is paraphyletic. Our study focuses on resolving relationships among lastreopsid ferns ( , Megalastrum Rumohra ), evolution morphological characters, an understanding temporal spatial patterns have led to current diversity geographical distribution its extant species.

We performed a phylogenetic analysis of the traditionally recognized genera bolbitidoid ferns (i.e., Arthrobotrya, Bolbitis, Elaphoglossum, Lomagramma, and Teratophyllum) using two noncoding chloroplast spacers: trnL‐trnF rps4‐trnS. The sampling included 57 species, which 55 had not been sequenced previously. results supported monophyly Teratophyllum; however, Bolbitis was resolved as polyphyletic. A clade eight Neotropical species currently placed in is sister to other Bolbitis. refer this...
Abstract Phylogenetic divergence-time estimation has been revolutionized by two recent developments: 1) total-evidence dating (or "tip-dating") approaches that allow for the incorporation of fossils as tips in analysis, with their phylogenetic and temporal relationships to extant taxa inferred from data 2) fossilized birth-death (FBD) class tree models capture processes produce (speciation, extinction, fossilization) thus provide a coherent biologically interpretable prior. To explore...
Abstract— The generic classification of the Thelypteridaceae has been subject much controversy. Proposed taxonomic systems have varied from recognizing approximately 1200 species in family within single genus Thelypteris , to favoring upwards 30 genera. Insights on intrafamilial relationships, especially for neotropical taxa, gained recent phylogenetic studies; however, most classification, 10 recognized genera are either non-monophyletic or untested. We sequenced 407 nuclear loci 621...
Functional traits determine how species interact with their abiotic and biotic environment. In turn, functional diversity describes assemblages of as a whole are adapted to environment, which also determines they might react changing conditions. To fully understand diversity, it is fundamental (a) disentangle the influences environmental filtering richness from each other, (b) assess if trait space saturates at high levels richness, (c) changes in numbers affect relative importance niche...
Recent phylogenetic analyses of grammitid ferns (Polypodiaceae) have demonstrated that some genera recognized within this clade are not monophyletic. We focus on resolving the circumscriptions large Neotropical by focusing a clade, identified in previous analyses, includes monophyletic genus Melpomene, plus portions two polyphyletic genera, Lellingeria and Terpsichore. Phylogenetic using chloroplast markers atpB, rbcL, trnL-F, along with 109 morphological characters, resolve ingroup as...
Premise of research. Epiphytes are prominent in many tropical floras; however, the evolution epiphytism, especially among ferns, remains poorly understood. Transitions habit have been proposed as evolutionary stepping stones radiation ferns epiphytic niche, with hemiepiphytes playing an important role. However, few examples hemiepiphytism conclusively documented and evidence for this transition is limited. Because lack information, relationship between epiphytism unclear. We fill gap new...
Premise of the Study Until recently, most phylogenetic studies ferns were based on chloroplast genes. Evolutionary inferences these data can be incomplete because characters are from a single linkage group and uniparentally inherited. These limitations particularly acute in hybridization, which is prevalent ferns; fern hybrids common able to hybridize across highly diverged lineages, up 60 million years since divergence one documented case. However, it not yet clear what effect such...
Pteridophytes-vascular land plants that disperse by spores-are a powerful system for studying plant evolution, particularly with respect to the impact of abiotic factors on evolutionary trajectories through deep time. However, our ability use pteridophytes investigate such questions-or capitalize ecological and conservation-related applications group-has been impaired relative isolation neo- paleobotanical research communities absence large-scale biodiversity data sources. Here we present...
Abstract Modern ferns diversified simultaneously with the rise of angiosperms. This pattern is arguably consequence ecological opportunities presented by shady and moist habitats that emerged advent angiosperm‐dominated habitats. hypothesis was tested applying phylogenetic comparative methods investigated role shaded in fern diversification across 1397 species from 37 families. Our results showed a significant positive correlation between occupancy rates phylogeny compared to those open high...
Wet ashing was used to study the occurrence of silica bodies in fern family Pteridaceae. They were recovered 48 77 species examined. Silica Pteridaceae are elongate, ranging from 90–1320 × 5–40 µm, linear elliptic, with blunt or acute apices and smooth sinuate sides. All previous records venuloid idioblasts among that examined confirmed by results this study, corroborating our assumptions regarding presence bodies. In contrast, absence incorrect; many Adiantum, for example, present but...
The recognition of monophyletic genera for groups that have high levels homoplastic morphological characters and/or conflicting results obtained by different studies can be difficult. Such is the case in grammitid ferns, a clade within Polypodiaceae. In this study, we aim to resolve relationships among four clades which been previously recovered either as polytomy or with topologies, goal circumscribing genera. •The sampling included 89 specimens representing 61 species, and sequences were...
PREMISE OF THE STUDY: This paper investigates the occurrence and evolution of aluminum (Al) accumulation within ferns lycophytes, which is characterized by Al concentrations above 1000 mg·kg −1 in aboveground plant tissues. We hypothesize that this feature more common than angiosperms, potentially correlated with growth form other chemical elements. METHODS: Aluminum were obtained from novel analyses literature for a total 354 specimens 307 species. Moreover, semiquantitative aluminon test...
A global consortium of nearly 100 systematists recently published a community-derived classification for extant pteridophytes (PPG I, 2016).This work, synthesizing morphological and molecular data, recognized 18 lycophyte 319 fern genera in 51 families, 14 orders, 2 classes.Using monophyly as defining criterion, while affirming the importance stability names circumscriptions, contributors produced summary statement then-current taxonomic hypotheses to serve resource scientific community...
