Cross-species GO enrichment visualization

[ARW-UBT]

Hello,
we have performed exposition experiments to various soil makrofauna (worms, arthropods, ...) and identified differentially expressed genes by RNA-Seq. GO enrichment analyses (Fisher's extact tests, GSEA) allowed us to identify enriched and depleted GO term from these genes/rnaked lists.
Since we observed many overlaps of GO terms in these species-specifi GO lists, we are seeking for tools to create GO network graphs from these GO lists of various organisms. To my knowledge, most GO network tools require species-specific GO annotations to create network graphs.
I would very much appreciate your ideas on how to visualize/compare GO enrichment results from multiple species.
Best regards,
