Anaulus and Asterionellopsis

Molecular dataset composed of alignments and bayesian phylogenetic trees used to identify species of Anaulus and Asterionellopsis (diatoms) from Brazil in the manuscript: Surf-diatoms from sandy beaches on the Eastern Coast of South America (Brazil): the identification of Anaulus Ehrenberg and Asterionellopsis Round published in Botanica Marina. DOI:10.1515/bot-2022-0067
- Sequences deposited in Genbank were edited, aligned with the ClustalW algorithm in the MEGA-X Program.
- These alignments were used to built the bayesian phylogenetic trees, the best-fit model for each data matrix was estimated using the Akaike Information Criterion by the software JModeltest 2 and trees were built using the software MrBayes 3.2.3.
- The alignments are in two formats (.FAS and .NEXUS) and were used as input to the Automatic Barcode Gap Discovery models for primary species delimitation (ABGD) and Assemble Species by Automatic Partitioning (ASAP).
- The trees are in two formats: .TRE and .NEXUS. Trees composed of all sequences were used to understand the phylogenetic relationship between strains. While, trees composed only of haplotypes were used as input to the Poisson Tree Processes (PTP).
