🚨 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.

Digesting Food Studies—Episode 115: Fisheries Diversification
https://rss.com/podcasts/digesting-food-studies/2477576/

Diversification is a survival strategy in many food systems, from biomes to economies to cuisine. This episode is about many of those things, including green sea urchins and the Wolastoqiyik Wahsipekuk First Nation’s approach to fisheries and food-making.

The article in focus is Charlotte Gagnon-Lewis’s “Fishing amongst industrial ghosts: The challenges of green sea urchin diversification in Eastern Canada.” (https://doi.org/10.15353/cfs-rcea.v12i1.680)

Plus, Alexia Moyer shares a story from the Montréal Biodome, and master student Adelle D’Urzo Paugh responds to Charlotte’s article with reflections on participatory co-learning and the Capitalocene.

China Leads Global Sericulture Market Growth

The global sericulture market is projected to reach $468.4B by 2031, driven by China’s dominance, expanding silk uses in cosmetics and medicine, and Asia-Pacific policy support.
