Land-use intensification and resulting habitat loss are put forward as the
main causes of flower visitor decline. However, the impact of
urbanization, the prime driver of land-use intensification in Europe, is
poorly studied. In particular, our understanding of whether and how it
affects the composition and functioning of flower visitor assemblages is
scant, yet required to cope with increasing urbanization worldwide. Here,
we use a nation-wide dataset of plant-flower visitor (Coleoptera, Diptera,
Hymenoptera, Lepidoptera) interactions sampled by citizen scientists
following a standardized protocol to assess macroecological changes in
richness and composition of flower visitor communities with urbanization.
We measured the community composition by quantifying the relative
occurrence of generalist and specialist flower visitors based on their
specialisation on flowering plant families. We show that urbanization is
associated with reduced flower visitor richness and a shift in community
composition toward generalist insects, indicating a modification of the
functional composition of communities. These results suggest that
urbanization affects not only the richness of flower visitor assemblages
but may also cause their large-scale functional homogenization. Future
research should focus on designing measures to reconcile urban development
with flower visitor conservation.
Flower visitor communities dataThis table provide the data of the 1606
flower visitors communities analysed as described in the main text of the
manuscript. Field “collection_id” is a unique ID number for each flower
visitor community; field “long” and “lat” provide longitude and latitude
of the site sampled. Field “volunteer_id” gives a unique ID number for
each volunteer observing data. Field “prop_ins_withCSI” gives, for each
flower visitor community, the proportion of insect that were available for
the calculation of the CSI (i.e. for each collection, the proportion of
insects with a defined specialisation index). Field “prop_urban_1km” is
the proportion of urban areas within 1km of the sampling sites. Fields
“richness_flovis” and “CSI_flovis” are respectively the richness and the
Community Specialisation Index of the flower visitor communities.Deguines
et al 2016_flovisdata.xlsxDeguines et al 2016_ColdataThis table provide
the data of the 677 Coleoptera communities analysed as described in
Appendix 1. Field “collection_id” is a unique ID number for each
Coleoptera community; field “long” and “lat” provide longitude and
latitude of the site sampled. Field “volunteer_id” gives a unique ID
number for each volunteer observing data. Field “prop_Col_withCSI” gives,
for each Coleoptera community, the proportion of insect that were
available for the calculation of the CSI (i.e. for each collection, the
proportion of insects with a defined specialisation index). Field
“prop_urban_1km” is the proportion of urban areas within 1km of the
sampling sites. Fields “richness_Col” and “CSI_Col” are respectively the
richness and the Community Specialisation Index of the Coleoptera
communities.Deguines et al 2016_DipdataThis table provide the data of the
843 Diptera communities analysed as described in Appendix 1. Field
“collection_id” is a unique ID number for each Diptera community; field
“long” and “lat” provide longitude and latitude of the site sampled. Field
“volunteer_id” gives a unique ID number for each volunteer observing data.
Field “prop_Dip_withCSI” gives, for each Diptera community, the proportion
of insect that were available for the calculation of the CSI (i.e. for
each collection, the proportion of insects with a defined specialisation
index). Field “prop_urban_1km” is the proportion of urban areas within 1km
of the sampling sites. Fields “richness_Dip” and “CSI_Dip” are
respectively the richness and the Community Specialisation Index of the
Diptera communities.Deguines et al 2016_HymdataThis table provide the data
of the 1159 Hymenoptera communities analysed as described in Appendix 1.
Field “collection_id” is a unique ID number for each Hymenoptera
community; field “long” and “lat” provide longitude and latitude of the
site sampled. Field “volunteer_id” gives a unique ID number for each
volunteer observing data. Field “prop_Hym_withCSI” gives, for each
Hymenoptera community, the proportion of insect that were available for
the calculation of the CSI (i.e. for each collection, the proportion of
insects with a defined specialisation index). Field “prop_urban_1km” is
the proportion of urban areas within 1km of the sampling sites. Fields
“richness_Hym” and “CSI_Hym” are respectively the richness and the
Community Specialisation Index of the Hymenoptera communities.Deguines et
al 2016_LepdataThis table provide the data of the 337 Lepidoptera
communities analysed as described in Appendix 1. Field “collection_id” is
a unique ID number for each Lepidoptera community; field “long” and “lat”
provide longitude and latitude of the site sampled. Field “volunteer_id”
gives a unique ID number for each volunteer observing data. Field
“prop_Lep_withCSI” gives, for each Lepidoptera community, the proportion
of insect that were available for the calculation of the CSI (i.e. for
each collection, the proportion of insects with a defined specialisation
index). Field “prop_urban_1km” is the proportion of urban areas within 1km
of the sampling sites. Fields “richness_Lep” and “CSI_Lep” are
respectively the richness and the Community Specialisation Index of the
Lepidoptera communities.
