Figure 1. General framework of this manuscript. Starting with the current mature community (1), different seed dispersal mechanisms determine how the seeds of the different species are distributed in the landscape (the first spatial template). This determines how the emerging seedlings are embedded into the biotic seedscape (input ), which is given by the mutualist and antagonist organisms shared with their neighbours (2, Seedling emergence). The seedscape affects the subsequent processes along the species ontogeny (output ), including the transition to sapling (3) and sapling establishment (4), thereby shaping the assembly of the next generation of the mature plant community (5).
Figure 2. Distribution of the proportion of shared organisms between pairs of woody species at the MFJ and MFS plots. Based on the number δfi of shared organisms (for ij ) or unique organisms (i = j ), we determined for each species pair the proportionδfi /δff of shared organisms, and plotted the cumulative distribution of the valuesδfi /δff , taken over all species pairs f -i . For completely species-specific organisms (i.e., δfi /δff = 0 for ij andδfi /δff = 1 for i =j ), we obtain values of (O − 1)/O for the cumulative distribution, where O is the number of species of the organisms. Thus, the higher the curve, the higher the host specificity.
Figure 3. Results of the spatial analyses of shared organisms for the sapling saplings (a – d), sapling - adults (e - h) and adults - adults (i – l) analysis, separately for plot (MFJ: solid lines, MFS: dashed lines) and fruit type (fleshy: red, dry: grey). The x-axis indicates the distance from the focal plant, and the y-axis shows the standardized effect sizes of the summary functionαf,phy (r ), which is the expected number of organisms shared between a randomly selected focal plant of the given type and a randomly selected neighbour within distance r . Values < −1.96 indicate that significantly fewer than expected organisms are shared, values > 1.96 indicate that more than expected organisms are shared, and otherwise results are non-significant. The pointwise simulation envelopes were determined based on 999 simulations of the toroidal shift null model.
Figure 4. Results of the spatial analyses of the cumulative spatially-explicit Simpson index, which gives the proportion of heterospecific neighbours within distance r of an individual of dry-fruited species (or fleshy-fruited species). The x-axis indicates the distance from the focal plant, and y-axis shows the Simpson indexαf (r ), where the dots are the observed summary function, the grey areas are the pointwise 5% simulation envelopes, and the grey lines are the expectations under the toroidal shift null model. Results were obtained by abundance-weighted averaging the species-level results of all fleshy-fruited species, and of all dry-fruited species.
