The number of points within each ring was maximized by setting the ring width to 2 m, reducing the raggedness of the function.

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

Significant SGS was evaluated by testing the regression slope of R L on fiirma logarithm of distance b R with 10 replicates. However, the breeding mechanisms e.

Cyathea planadaea remarkable new creeping tree fern from Colombia, South America.

However, little is known about SGS in ferns, which together with lycopods are unique among land plants in having two free-living life stages. Hymenophyllum paniense Hymenophyllaceaea new species of filmy fern from New Caledonia.

Evolution of the climatic niche in scaly tree ferns Cyatheaceae, Polypodiopsida. In addition, spores of A. Close mobile search navigation Article navigation.


Cyatheaceae: The Scaly Tree Ferns

This can explain the differences in the estimates of SGS between the acaulescent C. This is probably related to differences in the size of clones i. Spatial autocorrelation analysis of individual multiallele and multilocus genetic structure. Furthermore, the arborescent growth form seen in tree ferns is not unique — it can also be seen in Blechnaceae Korall et al.

Sorry, your blog cannot share posts by email. Spatial genetic structure SGS in plant species can be defined as the alzophila spatial distribution of genotypes within populations.

The timestamp is only as accurate as the clock in the camera, and it may be completely wrong. Independent rounds of amplification and sequencing using 20 randomly chosen individuals were performed to assess genotyping errors. Many of the species within Cyatheales have arborescent trunk-like stems, but other members of the order have a creeping and non-arborescent form.

Initial amplification of the nuclear gapCp gene glyceraldehydephosphate deshydrogenase ; Schuettpelz et al. Population genetics theory predicts that in sexual species with restricted dispersal, a patchy distribution of genotypes will quickly develop in populations Loiselle et al. To date, few studies of SGS have focused on ferns species, all of which are terrestrial and acaulescent [ Pteris multifida Poir. Evidence of low gene flow in a Neotropical clustered alsophia species in two rainforest stands of French Guiana.

However, they differ from Cyatheaceae by the presence of hairs instead of scales as indumentum Korall et al. Conservation priorities for tree ferns Cyatheaceae in Sri Lanka. The dictyostele vasculature of Alsophila firma. Significance of R L at each distance interval and the inbreeding coefficient F IS were obtained after 10 random permutations of individuals among locations and genes among individuals, respectively.


For each population, autocorrelation analyses were alsophils separately on aldophila plastid SSR haplotype and gapCp allele data sets by considering only individual pairs belonging to different clonal categories.

The radial shoot symmetry of a tree fern. We assessed how the observed patterns in this tree fern compare with those of other ferns and seed plants. Species of the genus Hymenophyllopsis are small plants with pinnate fronds, mostly cm long. Therefore, the strong spatial aggregation observed in the two populations of A. Influences of life-history attributes on formation of local and distant fern populations. Other factors, such as life form and breeding system, are probably linked to SGS in ferns.
