🚨 new #preprint online! 🚨 We study structure-stability relations in #MultiplexNetworks , using #tree-#liana interaction #networks from #Ghana as inspiration. We show that the stabilising effect of #modularity heavily depends on intra-guild interactions and is largest in case of intra-guild facilitation, highlighting the need to study how patterns in inter- and intraguild interactions jointly affect #EcosystemStability. #TheoreticalEcology #EcologicalNetworks

Stabilising effect of modularity in antagonistic networks depends on intraguild interactions

Existing literature on ecological networks provides valuable insights into the structure-stability relation of antagonistic, mutualistic or competitive systems, but it remains unclear whether these insights also apply to networks that contain a mix of different interaction types. Here, we study the effect of modularity on stability in systems that contain not only antagonistic interactions between two guilds, but also competition, facilitation or even antagonism within each guild, inspired by Gh

🚨 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 natur
