Phylogenomics of Baetidae: A Comparison in Classification
Avery Larsen1, T Heath Ogden1 This study focused on the evolutionary relationships of the family Baetidae, one of the three largest families in Ephemeroptera. Baetidae is of phylogenetic interest because of its somewhat basal position in the order and its diverse and variatied life histories and morphological characteristics. This analysis was carried out using Anchored Hybrid Enrichment from over 450 protein coding loci from 45 baetid ingroup taxa and 5 outgroup taxa. The data was analyzed as DNA (1st and 2nd positions in the codons) and as translated amino acid sequences in both maximum likelihood and Bayesian methodological frameworks. The results are compared to the recognized clades and classifications seen in previous phylogenetic proposals (Cruz et al. 2021) and suggest monophyly within subgroup Cloeoninae. Central Research questions: 1) What can anchored hybrid enrichment analyses show about the relationships and supposed subgroups of the Baetidae family? 2) Are the main lineages (subfamilies) supported as monophyletic with all combined data? Keywords: Ephemeroptera, Phylogenetics, Anchored hybrid enrichment, Baetidae References CRUZ, P. V. et al.
