| dc.description | Anomalocosmoecus illiesi is a macroinvertebrate, corresponding to the order Trichoptera. This exclusive freshwater species is found in the high moorlands of the Andean zone of Ecuador. Anomalocosmoecus illiesi larvae are highly sensitive to environmental changes, and therefore their abundance and presence can act as indicators of water quality. Curiously, this species is present in every mountain sampled in Ecuador and, unlike other genera of this same order, an endemism is not shown for each mountain. This makes this species very interesting to study since the geographical relations of the different populations can be established and infer at what moment they have been separated or if they are still connected, being from different mountains. Studying these population variations at the genetic level is one of the bases for understanding the distribution of these high mountain aquatic species. The present study has the purpose of evaluating the genetic diversity between populations of Anomalocosmoecus illiesi. For this, specimens of this species collected in different mountains of the Andean region of Ecuador were used. These specimens have been previously identified using morphological taxonomy techniques. To study the variations at the population level, the 3 'region of the cytochrome oxidase subunit I (COI) gene was used. The research was carried out among the populations of the Cayambe volcano (CAY), Papallacta (PAP), Cotopaxi volcano (PI), Illinizas volcano (SP), Carchi (CAR), Chimborazo volcano sand (CH) and the National Park Boxes (CAJS). Molecular analyzes revealed that there are no shared haplotypes between the populations of A.illiesi, indicating that there is isolation between the populations of different systems. On the other hand, the nonsignificant results of the neutrality tests are shown as evidence that (CH), (SN), (PAP), (CAJS), (CAY) and (ACH) are stable populations, while the absence of polymorphisms in (CAR), (SP) and (PI) is indicative that they are populations that are very isolated and localized. Through an AMOVA analysis, the existence of a geographical barrier was determined, which separates the populations of A.illiesi on both sides of the mountain range. | en |
