The world is rapidly urbanizing, thereby transforming natural landscapes
and changing the abundance and distribution of organisms. However,
insights into the effects of urbanization on species interactions, and
plant-pathogen interactions in particular, are lacking. We investigated
the effects of urbanization on powdery mildew infection on Quercus robur
at continental and within-city scales. At the continental scale, we
compared infection levels between urban and rural areas of different-sized
cities in Europe, and investigated whether plant traits, climatic
variables and CO2 emissions mediated the effect of urbanization on
infection levels. Within one large city (Stockholm, Sweden), we further
explored whether local habitat features and spatial connectivity
influenced infection levels during multiple years. At the continental
scale, infection severity was consistently higher on trees in urban than
rural areas, with some indication that temperature mediated this effect.
Within Stockholm city, temperature had no effect, while local accumulation
of leaf litter negatively affected powdery mildew incidence in one out of
three years, and more connected trees had lower infection levels. This
study is the first to describe the effects of urbanization on
plant-pathogen interactions both within and among cities, and to uncover
the potential mechanisms behind the observed patterns at each scale.
Dataset contains 2 field collections: Oak leaves collected in urban and
rural areas at the continental scale (5 trees per area), including small,
medium and large cities in Spain, France, the Netherlands, Denmark, Sweden
and Finland. Oak leaves collected within one large city (Stockholm,
Sweden), during 3 years (2017-2019). All oak leaves were scored for
powdery mildew infection.
