Time travelling through local ecological knowledge regarding an endangered species

Ronaldo Sousa‘s work on the role of local ecological knowledge regarding the endangered species Margaritifera margaritifera, the European freshwater pearl mussel, was highlighted in the media.  The research used a combination of local ecological knowledge (LEK) and field sampling to assess past and current distribution and conservation status of this endangered species in Cávado and Neiva Rivers (Portugal). Face-to-face interviews were performed in both rivers and  the entire area, where the respondents confirmed the historical presence of this species, was sampled. Abiotic characterization, water quality and fish diversity were also assessed in both rivers. It was found that freshwater pearl mussels are now possibly extinct in Cávado River but almost 50% of the respondents confirmed its presence in the past, especially elders that lived in villages near its historical distribution.
