Lignin diversity helps plants thrive on land – without them, they become small, sterile plants that produce far less biomass. 🪴

This is revealed in a new study in @newphyt.bsky.social by @stockholm-uni.bsky.social @bolincentre.bsky.social @uspoficial.bsky.social & #TUAT 👇

Dandelions that clone themselves still make pollen, but why? The #NoSexPoorPollen project led by @yannickwoudstra.bsky.social studies how pollen degrades when it’s no longer needed for sex, and what that means for evolution 🌼

New in @oikosjournal.bsky.social! 📃

The study, led by Peter Hambäck at DEEP, explores how interactions between hosts and enemies shape biodiversity. Results show that bottom–up and top–down diversification don’t work the same way, and that parasitoids often adapt faster than their hosts.👇
Bottom–up and top–down diversification: asymmetric processes over space and time
Coevolution in trophic interactions is often considered as a major factor underlying diversification in interacting species. Most focus hitherto has however been on bottom–up processes where host-ass...
