TAXON, Volume 75, Issue 5, October 2026.Abstract DNA sequences of loricate euglenids (genera Strombomonas and Trachelomonas) were analyzed in conjunction with detailed examinations of lorica and monad morphology. Phylogenetic analyses were conducted using 342 new sequences representing three molecular markers (149 nSSU, 102 nLSU, 91 cpSSU rDNA).

Target Capture of Ancient Shell DNA Enables Phylogenetic Reconstruction of Deep‐Sea Molluscs
Molecular Ecology Resources, Volume 26, Issue 7, October 2026.ABSTRACT Target capture is widely used to enrich endogenous DNA from calcium phosphate skeletal material in vertebrates, but its performance on calcium carbonate hard parts widely produced by invertebrates remains poorly understood. Here, we compared DNA recovery from four fresh and 12 ancient (eight radiocarbon‐dated to 1671–1135 years old before ...
