Valutazione dello stato morfologico ed ecologico di corsi d'acqua alpini: utilizzo e confronto dell'indice di qualità morfologica (IQM) e di un indice basato sugli odonati
This thesis deals with the assesment of morphological and ecological conditions of six Italian alpine rivers. Odonata (dragonflies) were chosen as bioindicators to assess the ecological status of river corridors while the assessment of th morphological status of the study cases was performed by using the Morphological Quality Index (MQI) Dragonflies demonstrated to be an effective bioindicator. The results also indicated a significant correlation between MQI and OQI and demonstrated the importance of river processes as drivers for the maintenance of a high diversity of habitats and species within the river corridor
