Temperature‐dependent pollinator‐mediated selection on floral thermoregulation

open access: yesNew 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
