Temperature‐dependent pollinator‐mediated selection on floral thermoregulation
New Phytologist, Volume 249, Issue 4, Page 1716-1726, February 2026.Summary The thermal environment is one of the most pervasive agents of selection. Most plants cannot choose their microclimate, so understanding how they cope with thermal variability is of critical concern. Several floral traits can modify the floral thermal microenvironment, which may alleviate negative impacts of thermal extremes on gametophytes and

New Phytologist, Volume 249, Issue 4, Page 2055-2070, February 2026.Summary Plants typically host insect communities composed of multiple trophic levels that are intricately linked through interactions mediated by the shared food plant. Hyperparasitoids are top‐level carnivores in such systems, preying on parasitoid larvae developing inside herbivores. These hyperparasitoids can dramatically reduce the effectiveness of
