| Popis: |
Higher-level relationships among major mayfly lineages remains controversial and previous molecular and morphological data are not very well supported (especially along the back bone and nodes deep within the topology) and tend to contradict each other in certain parts of the mayfly tree of life. This has led to classification systems that may not reflect the evolutionary history of the order. This project represents the largest phylogenetic analysis for mayflies to date. Over 450 targeted genomic protein coding regions (exons) were generated using the novel hybrid enrichment probe set (Ogden et al., 2019) for nearly 150 genera representing the main ephemeropteran clades. The dataset was analyzed as DNA position one and two in the codons and as amino acid sequences. The results allowed us to test the monophyly of many of the proposed higher-level groupings and to initiate a conversation about a new classification scheme for the order. This study supports the conclusion that more taxa and data, especially phylogenomic data, result in more robust trees and represent a good option for future studies in mayfly phylogenetics and systematics. |
