C/N ratio and decomposition of galled and non-galled leaves.

<p>(A) C/N ratio of galled (filled black quadrats) and non-galled leaves (filled grey circles) on the three sampling dates. Note that in June and August the C/N ratio was estimated from living leave tissue whereas in September leaf litter was analysed. (B) The average of remaining leaf litter mass of galled and non-galled leaves after six (May) and nine months (August) of decomposition compared to the leaf litter mass on the collection date in November. Values are averages across blocks and sites. Error bars indicate ± SE.
