Bibliografia in stile SIAM con Biblatex (biber e natbib)

Ciao a tutti.
Vorrei utilizzare lo stile SIAM per la bibliografia, utilizzando Biblatex con biber e natbib. Tuttavia ottengo il seguente errore:

! Package biblatex Error: Style ‘siam’ not found.

Esempio:

Come posso risolvere il problema? Grazie a tutti per l'aiuto.
