New paper: Phenotypic plasticity in plant defense across life stages: Inducibility, transgenerational induction, and transgenerational priming in wild radish

News by on September 2, 2021
Read the new paper just out in PNAS by former Dirzo Lab postdoc Mar Sobral, Rodolfo and former undergraduate student Isabelle Neylan. They found that wild radishes fend off caterpillars using “on-demand” anti-predator gene expression and these protections can extend to the next generation.

NOT all species are equal before global warming

News by on January 29, 2021
Our new study indicates that plant diversity initially increases with glacier retreat, but ultimately decreases once glaciers disappear. In other words, glacier retreat favors certain plants, but many species (22% of those analysed) may locally disappear or even go extinct once glaciers are gone. Interesting enough, plant facilitation prevails among pioneer species, whereas competition is more… Read more NOT all species are equal before global warming
