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

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

One of the pairs of pollen transfer networks from invaded (top) and non-invaded habitats (bottom).

<p>Plant stigma species are shown at the bottom of each network, whilst pollen types are at the top. Plant stigma species and pollen types are represented by rectangles, the size of which reflects their abundance; triangles connect the two if the pollen type is found on the stigma species, and the width of the triangle is related to the frequency of the interaction. Red interactions are those with balsam pollen, i.e. balsam pollen grains were found on the stigmas of the species with which it is linked. Codes for species are: 1- <i>Arctium minus</i>; 2 –<i>Buddleja davidii</i>; 3- <i>Calystegia sepium</i>; 4- <i>Circaea lutetiana</i>; 5 –<i>Cirsium arvense</i>; 6 –<i>Clematis vitalba</i>; 7 –<i>Dipsacus pilosus</i>; 8 –<i>Epilobium hirsutum</i>; 9 –<i>Filipendula ulmaria</i>; 10 –<i>Heracleum sphondylium</i>; 11 –<i>Rosa pimpinellifolia</i>; 12 –<i>Rubus fruticosus</i>; 13 –<i>Vicia sepium</i>; 14 –<i>Silene dioica</i>; 15 –Asteraceae 1; 16 –<i>Dipsacus</i> sp.; 17 –<i>Epilobium</i> sp.; 18 –<i>Impatiens glandulifera</i>; 19 –Morphotype (hereafter, M) 1; 20 –M10; 21 –M16; 22 –M4; 23 –M5; 24 –M6; 25 –M9; 26 –<i>Sonchus asper</i>; 27 <i>Taraxacum</i> sp.; 28 –Asteraceae 4; 29 –<i>Centaurea nigra</i>; 30 –<i>Cirsium</i> sp.; 31 –<i>Epilobium parviflorum</i>; 32 –<i>Geranium robertianum</i>; 33 –<i>Hypericum tetrapterum</i>; 34 –M11; 35 –M12; 36 –M13; 37 –M14; 38 –non identified; 39 –<i>Silene dioica</i>; 40 –<i>Sonchus</i> sp.; 41 –<i>Stachys sylvatica</i>; 42 –<i>Taraxacum officinale</i>; 43 –<i>Trifolium</i> sp.; 44 –<i>Trifolium dubium</i>; 45 –<i>Trifolium pratense</i>; 46 –<i>Trifolium repens</i>.</p

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
