Evaluación de las comunidades de himenópteros como indicadores del avance de la restauración ecológica en la Reserva Biológica Tapichalaca, Zamora Chinchipe

The effectiveness of the ecological restoration lies in the monitoring of its activities, for which different indicators have been used. This research tries to evaluate Hymenopteran communities as potential organisms that indicate the progress of the ecological restoration, which was carried out in the Tapichalaca Biological Reserve taking into account three levels of conservation (a well conserved zone, an area in the process of restoration, and a visibly degraded area) to know the sensitivity of the diversity of Hymenoptera families and their functional groups to different degrees of disturbance. Sampling was carried out for 6 consecutive weeks, obtaining a total of 1152 Hymenopterans (245 in the conserved area, 348 in the area under restoration, and 559 in the degraded zone). There were no differences regarding the functional groups, since there was a clear dominance of the parasitoids in the three zones. The greatest diversity of families was found in the area under restoration. Although no statistically significant differences were found in richness and abundance of families in relation to the conservation levels evaluated. A low sampling efficiency was also determined mainly in the conserved and restored areas. The post hoc analysis carried out found that the Diapriidae family is the one that shows the greatest relationship with the degraded zone, so it can be considered as a potential indicator family or this type of area. It is advisable to conduct a more exhaustive study of these families and the target areas. Key words: Hymenoptera, indicators, ecological restoration.
