| contents | Cryptic molecular diversity in the morphologically variable rotiferan Brachionus quadridentatus (Rotifera: Monogononta) Alma E. García-Morales Omar Domínguez-Domínguez Biología 18S monogonont Biodiversity species tree cytochrome c oxidase subunit I Brachionus quadridentatus is a morphologically variable species of rotifer distributed worldwide. The taxonomy of this species is confused, with numerous infrasubspecific variants described in the taxon: B. quadridentatus quadridentatus, B. quadridentatus f. brevispinus and B. quadridentatus f. cluniorbicularis. In this study, we explored genetic diversity among some populations of B. quadridentatus, using sequences of mitochondrial COI and nuclear 18S genes. The coalescent species delimitation analysis with the 18S gene highly supports the presence of at least three putative species within the B. quadridentatus complex. These results were in agreement with the phylogenetic and GMYC analysis using the 18S gene. However, we also found variation within each of these three putative species in morphology and COI gene sequences. There were seven morphologically differentiated lineages that were recovered as distinct based on COI gene sequences using the ABGD delimitation method. As such, mitonuclear discordance between COI and 18S phylogenies was found. The incongruence between mitochondrial and nuclear markers could be explained by incomplete lineage sorting. 2019 artículo científico 0034-7744 https://www.redalyc.org/articulo.oa?id=44965908002 https://www.redalyc.org/journal/449/44965908002/ https://www.redalyc.org/journal/449/44965908002/html/ https://www.redalyc.org/journal/449/44965908002/44965908002.epub https://www.redalyc.org/journal/449/44965908002/movil DOI 10.15517/RBT.V67I6.33996 es http://www.redalyc.org/revista.oa?id=449 Revista de Biología Tropical application/pdf Universidad de Costa Rica Revista de Biología Tropical (Costa Rica) Num.6 Vol.67 |
