Heat accumulation and spring freeze, both strongly influenced by snow cover, are key factors regulating the onset of phenology. In forest ecosystems, decreased cover due to climate change may differently impact heat occurrence freezes between canopy gap under tree canopy, leading varied phenological responses. this study, we examined how phenology seedling responds across microsites explored whether these responses species-specific. We conducted a manipulation experiment in planted northern Hokkaido, Japan, establishing five areas, each with control removal plot. Four dominant species were Snow significantly advanced budburst leaf-out microsites, more pronounced effect observed gap. Moreover, all four gap, whereas only Abies sachalinensis showed earlier canopy. Overall, our study demonstrated that projected winter warming led greater advancement seedlings compared species-specific

Climate change is shifting the growing seasons of plants, affecting species performance and biogeochemical cycles. Yet how timing autumn leaf senescence in Northern Hemisphere forests will remains uncertain. Using satellite, ground, carbon flux, experimental data, we show that early-season late-season warming have opposite effects on senescence, with a reversal occurring after year's longest day (the summer solstice). Across 84% northern forest area, increased temperature vegetation activity before solstice led to an earlier onset of, average, 1.9 ± 0.1 days per °C, whereas warmer post-solstice temperatures extended duration by 2.6 °C. The current trajectories toward slowed progression affect Hemisphere-wide trends growing-season length productivity.

Abstract Aim Ongoing climate warming has been widely reported to delay autumn phenology, which in turn impacts carbon, water, energy and nutrient balances at regional global scales. However, the underlying mechanisms of phenology responses change have not fully elucidated. The aims this study were determine whether brightening that was defined as increase surface solar radiation during recent decades affect opposite directions explore mechanisms.

Budbreak is one of the most observed and studied phenological phases in perennial plants, but predictions remain a challenge, largely due to our poor understanding dormancy. Two dimensions exposure temperature are generally used model budbreak: accumulation time spent at low temperatures (chilling) heat units (forcing). These two effects have well-established negative correlation; with more chilling, less forcing required for budbreak. Furthermore, temperate plant species assumed vary chilling requirements dormancy completion allowing proper Here, investigated from cold hardiness standpoint across many species, demonstrating that it should be accounted study accurately predict Most lost prior budbreak, rates loss (deacclimation) among leading different times Within deacclimation rate increases chill.

Abstract The concept of growing degree days (GDDs) is commonly used to predict phenological events in plants, assuming that plants develop proportionally the accumulated temperature. Two species‐specific parameters, T Base and t 0 (minimum temperature above which start date when GDDs begin accumulate), are considered for calculation. However, optimised thresholds wild herbaceous species remain sparse, therefore reliability models questionable. By employing several modelling approaches using records leaf unfolding flowering onset 87 collected six European botanical gardens between 2019 2024, we assessed GDD across a diverse array species. We further examined whether calculating can be large set single aimed estimate evaluate these species' temporal niche bud traits see specific groups species, work better. Our analyses revealed performed better than null model (i.e. mean years species) 84% 70% respectively. results showed with intermediate niches were less dependent on selection . Overall, found performance around 4°C most considering thresholds, predictions dates more accurate early‐growing regarding accumulation, larger values suitable later or onset. emphasise simple accumulating by studied approximate underlying parameters applying valid many use but advantageous small datasets would otherwise overfitted complex models.
