Comparative salinity tolerance in native flies from the subantarctic Kerguelen Islands: a metabolomic approach
International audience The quasi-extirpation of the cabbage Pringlea antiscorbutica in some locations at the Kerguelen Islands has large impacts on the distribution of the native fly Calycopteryx moseleyi. This insect has long been supposed as being subordinant to P. antiscorbutica until both larvae...
