An eco‐evolutionary optimality model explains the acclimated temperature response of photosynthesis

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2884-2899, June 2026.
Summary The optimal temperature of photosynthesis (Topt) generally increases with plant growth temperature. Changes in Topt are associated with changes in the maximum carboxylation capacity at 25°C (Vcmax25) and the maximum electron transport rate at 25°C (Jmax25). The ratio between Jmax25 and Vcmax25 declines with warming.

Arthropods on native versus alien woody plants: Understanding variation across host plant taxonomy and geography

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Alien plants have generally been shown to support reduced arthropod abundance, biomass, and diversity compared to native plant species, but inferences have typically come from studies limited in taxonomic and geographic scope. Here, we make use of data from a unique citizen science project, Caterpillars Count!, that consists of nearly 70,000 ...
