Morphological and DNA sequence data generated by Sanger sequencing and target capture methods for moss plants in the genus Fissidens from herbarium specimens
<p><span>Morphological evolution in mosses has long been hypothesized to accompany shifts in microhabitats and can be tested using comparative phylogenetics. These lines of inquiry have developed substantially, in part, by target capture sequencing allowing for phylogenomic scale data generated from herbarium specimens. In the present study, we test the relationship between taxonomically important morphological characters in the moss genus <em>Fissidens</em>, using both a 400-locus dataset generated using a target-capture approach as well as a three-locus phylogeny generated using sanger sequencing. Phylogenetic trees were generated using ASTRAL and Bayesian Inference and used to test the monophyly of subgenera/sections and provided the basis for ancestral character reconstruction and phylogenetic correlation analyses among five morphological characters as well as habitat moisture scored from literature. The characters <em>axillary hyaline nodules</em>, <em>limbidium</em>, <em>costa</em>, and <em>peristome morphology</em> as well as <em>sexual system</em>, <em>minimum habitat moisture</em>, <em>average habitat moisture</em>, <em>maximum habitat moisture</em>, and <em>habitat moisture niche breadth</em> each exhibit statistically significant phylogenetic signal. Significant correlations were found between the limbidium (phyllid/leaf border) and habitat moisture niche breadth, which could be interpreted as a more extensive <em>limbidium</em> enabling species to survive across a wider variety of habitats. Correlations were also found between <em>costa anatomy</em> and the <em>limbidum</em> of the gametophyte and sporophyte <em>peristome</em> <em>morphology</em>, as well as <em>average habitat moisture</em> and <em>sexual system</em>. Continued exploration of the relationships between morphological evolution, life history, and habitat will enable us to expand our understanding of functional morphology in mosses.</span></p>
Figures 4–5. Mitochondrial D-loop 474 in Molecular confirmation of the occurrence of Anguilla interioris (Actinopterygii: Anguilliformes) in North Maluku of Indonesia and mitochondrial DNA haplotype diversity among existing specimens
Figures 4–5. Mitochondrial D-loop 474 bp sequence analyses. (4) Phylogenetic analysis based on maximum likelihood algorithm with the sample codes, GenBank accession numbers and sample sites shown. Bootstrap percentages are shown at the tree nodes. (5) Haplotype network with the haplotypes labelled as H1 to H9. The circle size is proportional to the number of samples, and different sample sites are represented by different colours. Small white circle represents median vector which is the hypothesized or missing haplotype. Each dash on the line symbolizes one mutational step.
