📖 Further reading: The study underlines the need to re-examine the #paleoecology of these fascinating #arthropods and that additional discoveries like Polonolimulus may led to further revisions in our understanding of the #habitat and early #diversification of this group.

🌍 Geographic & evolutionary significance: Geometric #morphometric analysis places 𝘗𝘰𝘭𝘰𝘯𝘰𝘭𝘪𝘮𝘶𝘭𝘶𝘴 among the most morphologically extreme austrolimulids, most similar to forms from #australia. This extends their range to Central Europe and reveals Triassic xiphosurids were already widespread by the Early #Triassic, suggesting rapid post-Permian #diversification or earlier dispersal.

🚨 new #preprint 🚨

The evolutionary emergence of #EcologicalNetworks has been studied for decades but usually focussing on one type of interaction at a time, even though organisms naturally engage in multiple interaction types simultaneously. The combined effect of different interaction types on diversification thus remains unclear - until now. 😜

I hope you enjoy reading this fascinating story about ecological #pleiotropy and how it shapes #diversification patterns!

Between Friends and Foes: Evolutionary Diversification in Mutualistic-Antagonistic Networks

Biotic interactions can drive evolutionary diversification, but the underlying mechanisms differ depending on the type of interaction. For instance, Ehrlich and Raven's escape-and-radiate coevolution provides a pathway of diversification in antagonistic interactions, whereas in mutualistic networks, coevolution is hypothesized to result in trait convergence rather than diversification. The combined effect of mutualism and antagonism on diversification remains unclear, even though organisms naturally engage in multiple types of interactions simultaneously. Using an eco-evolutionary simulation model, we investigate diversification in tripartite ecological networks such as plant-pollinator-herbivore networks. We find that diversification patterns vary according to the way mutualism and antagonism are connected on the trait level. If the two interactions are governed by uncorrelated plant traits, we observe little diversification in the mutualistic and substantial diversification in the antagonistic subnetwork. By contrast, if the same plant trait mediates both mutualism and antagonism (an example of 'ecological pleiotropy'), diversification rates in all guilds become interdependent. In this case, even the mutualistic guild diversifies considerably when antagonism is strong, while strong mutualism restricts diversification also in the antagonistic guild. Our study underlines that the inclusion of multiple interaction types is necessary to advance our understanding of evolutionary dynamics in ecological networks. ### Competing Interest Statement The authors have declared no competing interest.
