The breeding productivity of dark‐bellied brent geese and curlew sandpipers in relation to changes in the numbers of arctic foxes and lemmings on the Taimyr Peninsula, Siberia —

There was a negative relationship between arctic fox numbers (or occupied lairs) and the breeding productivity of brent geese in the following year.
