dc.description.abstract | Systematic comparisons of species interactions in urban versus rural environments can
improve our understanding of shifts in ecological processes due to urbanization. However,
such studies are relatively uncommon and the mechanisms driving urbanization effects
on species interactions (e.g. between plants and insect herbivores) remain elusive. Here
we investigated the effects of urbanization on leaf herbivory by insect chewers and miners
associated with the English oak Quercus robur by sampling trees in rural and urban
areas throughout most of the latitudinal distribution of this species. In performing these
comparisons, we also controlled for the size of the urban areas (18 cities) and gathered data
on CO
2 emissions. In addition, we assessed whether urbanization affected leaf chemical
defences (phenolic compounds) and nutritional traits (phosphorus and nitrogen), and
whether such changes correlated with herbivory levels. Urbanization significantly reduced
leaf chewer damage but did not affect leaf miners. In addition, we found that leaves
from urban locations had lower levels of chemical defences (condensed and hydrolysable
tannins) and higher levels of nutrients (nitrogen and phosphorus) compared to leaves
in rural locations. The magnitude of urbanization effects on herbivory and leaf defences
was not contingent upon city size. Importantly, while the effects of urbanization on
chemical defences were associated with CO
2 emissions, changes in leaf chewer damage
were not associated with either leaf traits or CO
2 levels. These results suggest that effects
of urbanization on herbivory occur through mechanisms other than changes in the plant
traits measured here. Overall, our simultaneous assessment of insect herbivory, plant traits
and abiotic correlates advances our understanding of the main drivers of urbanization
effects on plant–herbivore interactions. | ca |
