Microcondylaea bonellii as a new host for the European bitterling Rhodeus amarus
Sousa, Ronaldo Gomes; Bogan, A. E.; Gonçalves, D. V.; Lajtner, J.; Prié, V.; Riccardi, N.; Shumka, S.; Teixeira, A.; Urbanska, M.; Varandas, S.We report for the first time that the freshwater mussel Microcondylaea bonellii (Ferussac, 1827) functions as a suitable host for the European bitterling Rhodeus amarus (Bloch, 1782). Given the recent expansion of R. amarus in Europe, the possible physiological cost (e.g. competition for oxygen, reduction in water circulation, and consequent impairment of filter-feeding) of this interaction may further affect t...
Freshwater conservation assessments in (semi-)arid regions: testing river inter...
Gomes-dos-Santos, A.; Froufe, E.; Gonçalves, D. V.; Sousa, Ronaldo Gomes; Prié, V.; Ghamizi, M.; Benaissa, H.; Varandas, S.; Teixeira, A.The IUCN Red List assessments are essentially based on population trends and range, namely Area of Occupancy (AOO) and Extent of Occupancy (EOO). Range estimations are based on fixed grids, but this is likely inappropriate for species living in river networks. Furthermore, AOO and EOO are measured using the whole hydrographic network, therefore disregarding temporary sections, which is particularly problematic ...
