For colonization success, should hosts 🌱 and microbes 🦠 travel alone, together, or swap partners along the way? Excited to share a new paper with Jerry Yu and @mfrederickson.bsky.social in which we test how microbial partners alter plant performance upon natural introductions: tinyurl.com/8u4268n6

Excited to share our new paper in which we test how competition alters adaptation at a warming range edge @science.org We find that competition can increase adaptation to warming when there is a shared evolutionary response to both biotic and abiotic drivers of selection: tinyurl.com/3j8s9t8b

Competition enables rapid adaptation to a warming range edge in a model plant community
Most predictions of whether populations will adapt to warming range edges ignore species interactions. We experimentally tested whether range-edge populations can adapt to warming within a competitive...

Highlights
The fossil record suggests that climate change was the major driver of plant extinctions and regional extirpations from the Pliocene until recently, when anthropogenic habitat loss became dominant.
Known recent plant extinctions are disproportionately few in comparison with well-studied animal taxa, but many more species are probably committed to inevitable extinction unless given targeted support.
Recent warm-edge extirpations demonstrate the growing impact of anthropogenic climate change and show that predictions of massive climate-driven extinctions later this century are plausible.
The proximate causes for population extirpations are still rarely known but are likely to be highly varied and both species and location specific."
