Laine  showed that the reproduction of bilberry ( '' Vaccinium myrtillus '') depended to some extent on the climate in the previous years (see section 14.7.3 for examples of this in trees), whereas Shevtsova et al.  showed no such response for co-occurring lingonberry and crowberry ( '' Empetrum nigrum '').
