New combinations and an overview of Cyathea subg. Generic delimitations of Cyatheaceae have differed substantially across various studies and have been hotly debated in recent years. However, the frequency of clonal growth in natural populations remains unexplored using genetic resources.

Tropicos | Name – Alsophila firma (Baker) D.S. Conant

For plants with mixed sexual and asexual reproduction, incorporating both aspects of reproduction is essential to make a correct inference about patterns of gene dispersal and inbreeding within populations Dutetch et al.

Worldwide distribution of Cyatheaceae based on data from Encyclopedia of Life www. The nuclear SNP genotypes were used to reconstruct gene alleles for each individual stem using the program Phase 2.

This assessment, however, would be limited by the difficulty of studying natural population of gametophytes, mainly resulting from highly similar gametophyte morphologies across species Conant, Furthermore, study of the spatial genetics and demography of the two life stages of ferns would be highly valuable in increasing our understanding of the causes of SGS in these plants.

Accordingly, both populations showed substantial levels of clonal diversity R0. In each population, all identifiable individual stems AH: Due to the lack of single nucleotide polymorphisms, we restricted our analyses to five mononucleotide microsatellites plastid SSRs located within these regions, which were subjected to direct cycle sequencing High Throughput Genomic Unit, University of Washington, Washington, DC, USA.

Contrary to our expectations, an outcrossing breeding system, wind dispersal and an arborescent life form did not translate into weak or no SGS. An edge correction was applied, where the number of points in an incomplete ring was divided by the proportion of the ring lying within the observation window Wiegand, Psilopsida; Equisetopsida; Marattiopsida; Polypodiopsida, which include 11 orders, and 37 families with ca.

The study of SGS in juvenile tree ferns would help us understand the processes involved in the establishment of new individuals within populations. Sorry, your blog cannot share posts by email.

Alsophila was reclassified to include ca. This file is made available under the Creative Commons CC0 1.

Oxford University Press is a department of the University of Oxford. Fifma ferns in the interior and the edge of a Mexican cloud forest remnant: Using the allele data for each individual i. We believe this to be unlikely for A.


Within-population spatial genetic structure, neighbourhood size and clonal subrange in the seagrass Cymodocea nodosa.

However, with evermore phylogenetic analyses and data botanists are beginning to piece together that main groups or genera within the family. Clonal diversity and distribution in Stenocereus eruca Cactaceaea narrow endemic cactus of the Sonoran Desert. Pollination of an endangered Caladenia species Orchidaceae by nectar-foraging behaviour of a widespread species of colletid bee.

Taxon, fjrma In this life cycle, meiosis and fertilization occur in different plants and dispersal is mainly achieved through propagules spores that develop prior to fertilization. To identify individual stems produced by a,sophila reproduction, we estimated the probability that two individuals share the same genomic combination plastid SSR haplotype and nuclear alleles by sexual reproduction p gen. The diminutive Hymenophyllopsis superba. However, the presence of pneumathodes may unite the clade, but it is also found in other leptopsporangiate ferns, and may represent the ancestral plesiomorphic condition of this group.
