Tree canopy shapes the survival of oak and beech saplings during the regeneration stage along an elevation‐driven temperature gradient

Journal of Ecology, Volume 114, Issue 7, July 2026.
Forests are complex, multilayered systems in which canopy cover strongly influences understorey microclimates. Here, we show that the temperature‐buffering effect of the forest canopy affects tree regeneration differently among species along an elevation gradient in the French Pyrenees.

Increased exposure to chilling advances the time to budburst in North American tree species [PDF]

Tree Physiology, 2017
The phenology of trees is highly susceptible to changing global temperatures. Leaf budburst advances with increasing spring temperatures, but can also be delayed when warmer winters reduce chilling exposure. Results from long-term observations show that increasing temperatures have triggered advanced budburst in the past decades, but some studies also ...

Winners and losers in subarctic moth communities in a changing climate: Marine regime shifts as predictors for terrestrial insect biomass

Insect Conservation and Diversity, Volume 19, Issue 4, Page 945-963, July 2026.
1972–2017, the total moth biomass ina subarctic community had a positive trend but biomass trends differ betweenmoth groups based on taxonomy, phenology and resource use. In the northern latitudes, outbreaking species impact greatly moth biomass Moth biomass is associated withtemperature variables and marine Regime shifts, which can be effective ...

Artificial light reduced the temperature responsiveness of Ginkgo budburst

Journal of Plant Ecology
Abstract Urbanization-induced warming advanced the timing of spring budburst, impacting on urban ecosystems. However, how urban artificial light affects the spring budburst and its spatial variation within species distribution are less studied, especially lacking experimental evidences.

Budburst and flowering intensity by the spraying of dormancy-breaking products in ‘Eva’ apple trees

Semina: Ciências Agrárias, 2019
Spraying of dormancy-breaking chemicals is a mandatory procedure to produce temperate fruits in low-chill regions. Although hydrogen cyanamide (HC) + mineral oil (MO) show efficiency enhancing budburst, the usage of HC is restricted in some countries due

Where is the optimum? Predicting the variation of selection along climatic gradients and the adaptive value of plasticity. A case study on tree phenology

Evolution Letters, 2020
Many theoretical models predict when genetic evolution and phenotypic plasticity allow adaptation to changing environmental conditions. These models generally assume stabilizing selection around some optimal phenotype. We however often ignore how optimal

Same damage, different story: Vertical decoupling of herbivore abundance and beech herbivory across forest layers

Journal of Ecology, Volume 114, Issue 6, June 2026.
This study shows that the relationship between herbivore abundance and herbivory can be decoupled across vertical forest layers through resource dilution, challenging the assumption that more herbivores result in more per‐leaf damage. The effects of woody plant diversity and structure on beech herbivores depend on whether a stratum functions as a ...

Effects of delayed winter pruning on vine performance and grape composition in cv. Merlot

BIO Web of Conferences, 2019
Delaying winter pruning until after budburst is a technique that can retard vine phenological phases and reduce grape sugar concentration at harvest. Given these characteristics, many studies have recently been conducted to verify the ability of pruning ...

Pruning date and hydrogen cyanamide effects on growth and yield of grapevine var. Cabernet Sauvignon

Advances in Horticultural Science
Harvesting the grapes before the monsoon season is crucial to ensure the quality of berry and bunches. This study aims to identify the optimal window for pruning and hydrogen cyanamide (HC) application to prepone the berry harvesting.

Will It Survive? Evaluating the Effects of Damage and Silviculture on Tree Seedling Survival Using Multi‐State Models

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Plantations are the spearhead of adaptive silviculture, yet we do not understand how damage from abiotic and biotic agents relates to seedlings’ survival. In this study, we used multi‐state models, which originate from the medical field, to evaluate the relation between ‘damage history’, silvicultural treatments, and planted tree survival.
