Effects of habitat characteristics and trophic level on the structure of plant-frugivore networks.

<p>Species specialisation (<i>d'</i>), network specialisation (<i>H₂'</i>), interaction diversity and robustness of plant-frugivore networks (n = 9) in relation to fruit abundance, fruiting plant species richness, canopy cover (%) and trophic level (plant <i>vs.</i> frugivore). To investigate effects on species specialization, trophic level was nested within plot in a linear mixed effect model; effects on all other dependent variables were analysed using linear models. Given are <i>R²</i>, <i>t</i> and <i>P</i> values, if applicable. Note: all significant or marginally significant <i>P values</i> are highlighted in bold.
