APPENDIX 1 in A study of the morphology and distribution of four Achnanthidium Kütz. species (Bacillariophyta), implications for ecological status assessment, and description of two new European species
APPENDIX 1. — Principal component analysis of Fourier shape harmonics for identified species. The biplot presents the first two axes with a total explained variance of 96.4 %.
APPENDIX 2 in A study of the morphology and distribution of four Achnanthidium Kütz. species (Bacillariophyta), implications for ecological status assessment, and description of two new European species
APPENDIX 2. — Linear discriminant analysis of Fourier shape harmonics for A. sieminskae Witkowski, Kulikowskiy & Riaux-Gob. from different geographic regions (Europe, Wales, Scotland and England). Specimens of A. caledonicum (Lange-Bert.) Lange-Bert. are used as the outgroup. The biplot presents the first two axes with a total explained variance of 90.3 %.
FIG. 19 in A study of the morphology and distribution of four Achnanthidium Kütz. species (Bacillariophyta), implications for ecological status assessment, and description of two new European species
FIG. 19. — Linear discriminant analysis of elliptic Fourier shape harmonics for identified species. The biplot presents the first 2 axes with a total explained variance of 81.3 %.
FIG. 21 in A study of the morphology and distribution of four Achnanthidium Kütz. species (Bacillariophyta), implications for ecological status assessment, and description of two new European species
FIG. 21. — Relationships between diatom assemblages, four Achnanthidium Kütz. species and land use in 52 streams, rivers and lakes of Scotland, United Kingdom. A, B, NMDS ordination (2D stress 0.1) of Bray-Curtis similarities of diatom assemblages: A, the vector plot shows the direction of linear increase in land use types and the multiple correlation of each of the land use categories with the diatom assemblages; B, the vector plot shows the direction of linear increase in the most abundant diatom species and the multiple correlation of each species with the diatom assemblages. C-F, bubble plots of species: the relative abundance of four diatom species in 52 diatom assemblages is represented by the circle size: C, Achnanthidium minutissimum (Kütz.) Czarn.; D, Achnanthidium sieminskae Witkowski, Kulikowskiy & Riaux-Gob.; E, Achnanthidium neomicrocephalum Lange-Bert. & F.Staab; F, Achnanthidium caledonicum (Lange-Bert.) Lange-Bert.

FIG. 3. — Achnanthidium caledonicum (Lange-Bert.) Lange-Bert.: A-B, specimens from Brunnsee, Germany; C-F, specimens from Scotland, 2012, 44sto; A, SEM external view of whole raphe valve and rapheless valve; B, SEM external view of whole raphe valve, mantle and girdle bands at pole; C, SEM external view of valve centre of raphe valve; D, SEM external view of valve centre of rapheless valve; E, SEM external view of pole of raphe valve; F, SEM external view of pole of rapheless valve. Scale bars: A, 10 µm; B, 5 µm; C-F, 3 µm.
Data supplementing the article "Assessing ecological status with diatoms DNA metabarcoding : scaling-up on a WFD monitoring network (Mayotte island, France)" V. Vasselon, F. Rimet, K. Tapolczai, A. Bouchez submitted to Ecological Indicators journal
<p>These data supplement the article"Assessing ecological status with DNA metabarcoding or microscopy? Comparison using benthic diatoms in tropical rivers" V. Vasselon, F. Rimet, K. Tapolczai, A. Bouchez submitted to Ecological Indicators journal.</p> <p>The directory contains the following files:</p> <p><strong>80 PGM sequencing libraries (raw data, fastq files).rar </strong>- contains the 80 fastq files provided by the sequencing platform with demultiplexed DNA reads (raw data prior any bioinformatics treatments).</p> <p><strong>80 fastq files information.xlsx</strong> - contains the information relative to the 80 samples including: the ID used in Mothur analyses (corresponding to the name of the fastq files), the sample name, the sampling site code, the name of the river, the monitoring network to which rivers belong, the year of sampling and the GPS coordinates of sampling sites.</p> <p><strong>OTU (95 percent of similarity) list of 80 Mayotte samples.xlsx</strong> - contains the final OTU list obtained after applying all the bioinformatics treatments (trimming, clustering,...): OTUs created at 95% of similarity, the number of DNA reads per sample was normalized at 5710 reads (the smallest values obtained in one sample). A DNA representative sequence and the taxonomic assignment determined using Mothur (using classify.otu command) are also provided for each OTU.</p>
