L'Espai Europeu d'Educació Superior s'ha convertit en un repte, un desafiament que implica assolir una convergència de titulacions universitàries equivalents. Per això es requereix una modificació del tradicional ensenyament, en el nostre cas, de la psicologia. En aquest article s'examina l'ensenyament de la psicologia al Institute of Psychological Sciences de la Universitat de Leeds (metodologia docent; avaluació i contingut curricular)

Dendrodrilus rubidus were sampled from a mine spoil soil at Coniston Copper Mine, an abandoned Cu mine in Cumbria, UK and a Cu-free control site. Earthworms were maintained for 14 d in both Kettering loam and a Moorland soil amended with Cu nitrate. Mortality, condition index, weight change and tissue concentration were determined. In both soils D. rubidus native to the mine site were able to tolerate significantly higher soil Cu concentrations (MWRT, p <= 0.001), and exhibited significantly less change in weight (t-test, p <= 0.001) and a lower loss in condition (t-test, p <= 0.001) than control earthworms. For a given soil Cu concentration tissue Cu concentrations were greater in the mine site earthworms. Low cocoon production and viability from the mine site population prevented the determination of toxicity parameters on the F1 generation and may be an indicator of the cost of tolerance to the population.
