Data from: A highly-resolved food web for insect seed predators in a species-rich tropical forest
The top-down and indirect effects of insects on plant communities depend on patterns of host use, which are often poorly documented, particularly in species-rich tropical forests. At Barro Colorado Island, Panama, we compiled the first food web quantifying trophic interactions between the majority of co-occurring woody plant species and their internally-feeding insect seed predators. Our study is based on more than 200,000 fruits representing 478 plant species, associated with 369 insect species. Insect host-specificity was remarkably high: only 20% of seed predator species were associated with more than one plant species, while each tree species experienced seed predation from a median of two insect species. Phylogeny, but not plant traits, explained patterns of seed predator attack. These data suggest that seed predators are unlikely to mediate indirect interactions such as apparent competition between plant species, but are consistent with their proposed contribution to maintaining plant diversity via the Janzen-Connell mechanism.

Fig. 1 Phylogenetic trees of the Carex Vesicariae alliance (left) and sect. Phacocystis (right) with indications of the clades and grades that were used in the text and for comparisons. The tree for sect. Phacocystis has been slightly modified from Dragon and Barrington (2009) by removing duplicate species that do not affect tree topology and by the removal of several basal taxa that do not change tree interpretation.

FIG. 5. Scanning electron micrographs of shell and opercular valves of (A) Hiroa stubbingsi Ross and Newman 1973 from Sulawesi, Indonesia and (B±I) Cionophora guillaumae sp. nov. (MNHN Ci 2803) from New Caledonia. (A) Lateral view of the margin of wall showing six radial (longitudinal) septa running normal to and separating the inner and outer lamina; note the transverse septa running between them and their more numerous marginal denticles that ®t into the grooves of the basis (see ®gure 2B). (B) External view of the wall of holotype showing the radiating rows of pillars on outer lamina of wall. (C) Internal view of wall of holotype showing the sheath and marginal teeth of the radial septa that ®t into the grooves in the basis (®gure 5I). (D) Lateral view of the margin of the wall of the holotype, showing four longitudinal (radial) septa with marginal denticles that ®t into the grooves of the basis and separated by a single transverse septum running parallel to the inner and outer laminae, and the U-shape valleys that run between the radiating rows of pillars on the outer lamina. (E) External view of right opercular plate of holotype. (F) Internal view of left opercular plate of holotype. (G) External view of left opercular plate of paratype (MNHN Ci 2804) showing possible trace of the external suture between tergal and scutal portions of the valve. (H) Internal view of rostral end of wall of paratype showing pair of ridges apparently demarcating the rostral margins of the bosses accommodating the expanded limbus adductorum of each opercular plate. (I) Basis of paratype illustrating internal grooves that accommodated the marginal teeth of the radial septa of the wall and the external tubes between them that accommodated host tissue. Scale bars: (A, I=1 mm; (B, C)=0.75 mm; (D)=0.5 mm; (E±H)= 0.25 mm.
