Figure 3 Delavaux (2026): Major traits hypothesized to impact the mutualist filter. A framework synthesizing mutualism traits hypothesized to impact the strength of the mutualist filter. Plant host traits include specificity, dependency, and multiple mutualists; mutualist traits include dispersal limitation, specificity, and dependency. Finally, species introductions may mediate the filter, with differing effects on the mainland relative to islands. An example within the mycorrhizal symbiosis contrasting arbuscular mycorrhizal (AM) and ectomycorrhizal (EM) mutualisms is given in the dark gray boxes. Although EM mutualisms are relatively stronger in three out of five traits predicted to increase the mutualist filter, research shows that AM plant species experience a stronger filter, likely due to the overriding effect of dispersal limitation.

#Mutualisms within light microhabitats are associated with sensory convergence in a mimetic butterfly community https://www.pnas.org/doi/10.1073/pnas.2422397122

"distantly related species living in the same pockets of #rainforest light have evolved remarkably similar visual systems... & butterflies that mimic each other's warning colours tend to live in the same lighting environments, likely enhancing their shared warning signal to predators"

Different spatial states of cooperative symbionts leading to different host–symbiont interactions.

I’m very excited to be headed to Portland for #esa2023 If anyone would like to meet up for coffee or a meal and chat #mutualisms #CommunityEcology #syntheticEcology #PUIs or really anything

Hello, my name is Otti and I am a lecturer at Newcastle university (UK). My research is in the #biophysics and #mathbiology of #microbes (#mathmodelling & #experiment). I have a particular interest in swimming microalgae and bacteria (#microswimmers) with application to sustainable #biotechnology. I have also worked on algal-bacterial #mutualisms between #soil species. I teach #mathematics to #engineering students, and am interested in #maths, #physics and #science #education and #outreach.

This weeks #MutualismsOnMain is an interaction that first got me interested in mutualisms! Ant-acacia mutualisms are a protection type interaction where the ant provides the plant with defense against herbivory while the plant provides a home and usually some food. These mutualisms are powerful—in some cases vastly shaping forest structure and communities! 📸 https://www.flickr.com/photos/kafka4prez shared under https://creativecommons.org/licenses/by-sa/2.0

Acacia leaf with beltain bodies (small white rice shaped structures at the tips of leaflets) is being held to the camera by a hand. At the base of the leaf a large thorn domatia where ants live has been made by the plant.

I’m going to post a regular series highlighting different #mutualisms each week. In this weeks #MutualismsOnMain let’s meet a fungal group I’m so enamored with right now. Epichloë are endophytes living in grass hosts. They provide the plant with protection from herbivores by producing a range of intense alkaloids. One neat feature of this microbe: vertical transmission! Plants can pass down their epichloë to their offspring.

Hi! I’m a #queer postdoc working on multispecies #mutualisms and all things #community #ecology. I’m building synthetic mutualistic networks with plants and AMF fungi 🍀🍄 The other half of my work relates to increasing #belongingness and #inclusivity in #STEM, currently starting a living learning community for 1st-yr bio students from under resourced backgrounds. I’m excited to build community here!
