Per studiare il modo in cui le popolazioni dei lupi evolvono bisogna far capo alle tracce che lasciano e analizzarle geneticamente. È il compito che Luca Fumagalli, direttore del Laboratorio di biologia della conservazione dell’Università di Losanna svolge da oltre 15 anni. Lo ha intervistato tvsvizzera.it e questo prima dei fatti di Cama.

I dati raccolti permettono di stabilire solo in maniera approssimativa il numero minimo di lupi presenti sul territorio. Prima di tutto perché si tratta di animali molto mobili, inoltre non è detto che depongano il loro DNA.
Secondariamente la maggior parte del materiale genetico analizzato a Losanna è raccolto in seguito ad attacchi a greggi. Non va poi dimenticato che le analisi sono complesse e il loro successo dipende dalla qualità del materiale genetico trovato. Da quando è attivo il laboratorio ha potuto individuare più di 90 esemplari differenti che sono transitati sul territorio elvetico.
