This (unreviewed) preprint discusses how rising temperatures threaten natural plant populations by disrupting reproductive processes, particularly gametogenesis, fertilization, and seed filling, often at lower temperature thresholds than those affecting photosynthesis, growth, or survival. The authors argue that ecological and evolutionary research has focused less on reproductive-stage outcomes and more on other fitness metrics when estimating resilience to warming. They advocate integrating pollen and ovule developmental metrics to improve predictions of population dynamics under future climates, and they note that doing so could also uncover mechanistic insights relevant to heat-stress vulnerability. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Temperatures are rising globally and threatening the persistence of natural plant populations. Elevated temperatures disrupt gametogenesis, fertilization, and seed filling, often at lower thresholds than those affecting photosynthesis, growth, or survival. While crop scientists have found that key reproductive stages are particularly vulnerable to heat stress across plant systems, ecological and evolutionary studies have largely focused on other fitness metrics to estimate populations’ resilience to warming. We advocate for integrating pollen and ovule developmental metrics into ecological and evolutionary studies to improve predictions of plant population dynamics under future climates. Such studies will offer not only a better understanding of how natural populations will respond to increasing temperature stress, but also are likely to reveal novel mechanistic insights that can be utilized to improve crop resilience in a warming world.
