Climate change is impacting forests in complex ways, with indirect effects arising from interactions between tree growth and reproduction often overlooked. Our 43-y study of European beech ( Fagus sylvatica ) showed that rising summer temperatures since 2005 have led to more frequent seed production events. This shift increases reproductive effort but depletes the trees’ stored resources due insufficient recovery periods crops. Consequently, annual ring increments declined by 28%, dropping a stable average 1.60 mm y −1 1980 1.16 thereafter. Importantly, this decline occurred without an accompanying trend drought, indicating altered patterns—not moisture stress—are driving reduction. creates “perfect storm”: Increased drains resources, viable output falls loss mast-seeding benefits via pollination lower predation, ongoing reduces current carbon uptake future potential. These compounding factors threaten sustainability Europe’s most widespread forest tree. findings unveil critical yet underrecognized mechanism which climate endangers ecosystems, emphasizing need consider demographic processes when assessing species vulnerability change.

Kyrgyzstan features the largest naturally occurring walnut forests in world. Their high plant biodiversity, including wild relatives to modern-day fruit species such as apple and pear, make them a valuable guardian of genetic diversity. Further, have economic importance for country. Climate change, however, poses major threat these ecosystems, particular since rises temperature are projected that well above global average. As studies on effects changing environmental conditions growth missing, we investigate climate sensitivity temporal stability thereof extreme responses along its full elevational gradient Kyrgyzstan. Whereas expected find shift from water- temperature-limitation over gradient, which may move upwards with recent warming, found be temperature-limited entire gradient. In decades, negative correlations between drought index SPEI tree growth, weakened. An up until now low stress is also substantiated by pointer-year analysis. Overall, our results show already affected though imminent risks drought-induced vitality loss seem still low. With ongoing this may, rapidly change.
