Ground flora species matrix

Plant species found in the ground flora of each plot. Data collected in the field. Species names are abbreviated to the first three letters of the genus followed by the first three letters of the species. Full names can be found in the read me file. Plot information for each code can be found in the 'Plant and leaf-miner richness' file

Woodland species matrix

Woodland species found in the ground flora of each plot. Data collected in the field. Species names are abbreviated to the first three letters of the genus followed by the first three letters of the species. Full names can be found in the read me file. Plot information for each code can be found in the 'Plant and leaf-miner richness' file

Plant and leaf-miner richness

Plant and leaf-miner species richness of plots. Data collected in the field. 'Plant species' refers to the species richness of the ground flora. 'Woodland species' refers to the species richness of woodland species in the ground flora

Appendix B. Comparison of community descriptors between the control and experimental plots of each pair for the control-impact (CI) design.

Comparison of community descriptors between the control and experimental plots of each pair for the control-impact (CI) design

The predicted geometric mean number (± S.E.) of (a) alien balsam (<i>Impatiens glandulifera</i>), (b) conspecific and (c) heterospecific pollen grains on dry, wet and semidry stigmas in invaded and non-invaded habitats using generalized linear mixed-effects models.

<p>The only significant pairwise difference, based on posteriori tests, was found between dry stigmas in invaded and non-invaded habitats.</p

Field experiment plant-pollinator data 2011

2011 pollinator survey data from the field experiment (North Wyke Wide-scale Enhancement of Biodiversity Project) including dates, grassland plot treatments, survey times, plant species and the associated visiting pollinator species. Each row shows a plant-pollinator interaction

Frequency histograms showing the number of pollen grains per stigma species in (a) both habitats pooled, (b) in invaded habitats and (c) in non-invaded habitats.
