Reproductive isolation, morphological and ecological differentiation among cryptic species of Euchlanis dilatata , with the description of four new species

摘要: Morphological approaches may not provide sufficient resolution for species delineation. Thus, we used an integrated approach that included molecular and ecological characters as well morphological features to gain a better estimate of diversity improve our understanding the speciation process within rotifers. Previously, seven putative cryptic were found Euchlanis dilatata complex based on nuclear marker. Here, investigated reproductive isolation, variation in trophi morphology, life history characteristics among representatives some these species. Mating success between each was 0–1.1%; lower than positive controls (intra-clonal: 15.6–43.9%). SEM images representing individuals from all lineages morphometric analyses. Using Discriminant Analysis, 64% correctly assigned Five clonal lineages, species, table experiments with varying temperature conductivity. Age-specific fecundity increased under high expectancy decreased There characteristics, such generation time. Applying integrative taxonomy approach, examined boundaries E. described four them new
