Kolstad, Anders Lorentzen; Snøan, Ingrid Bekken; Austrheim, Gunnar; Bollandsås, Ole Martin; Solberg, Erling Johan; Speed, James David Mervyn (Peer reviewed; Journal article, 2021)Large herbivores are often classed as ecosystem engineers, and when they become scarce or overabundant, this can alter ecosystem states and influence climate forcing potentials. This realization has spurred a call to ... -
