    Undervisning

    BIO-3013 Nordlige næringsnetts økologi ( - 2019). Tar utgangspunkt i rammeverket for næringsnett for å forstå økosystemers struktur og funksjon. Tar utgangspunkt i veletablert økologisk teori for trofiske interaksjoner (produsent-forbruker relasjoner) mellom planter, plantespisere og kjøttetere.
