Post‐budburst hand finishing of winter spur pruning can delay technological ripening without altering phenolic maturity of Merlot berries

, 2020
Background and Aims Global warming can lead to technological ripening occurring in advance of phenolic maturity for red wine cultivars. This study evaluated the effect of post‐budburst winter pruning on the phenology, yield components, berry composition

Multivariate models improve accuracy of genomic prediction for spring frost tolerance in Norway spruce

The Plant Genome, Volume 18, Issue 4, December 2025.
Abstract Warming spring temperatures increase the risk of frost damage to emerging Norway spruce (Picea abies) buds by advancing their spring phenology and increasing the frost event frequency. We present a field‐based electrolyte leakage assay to assess basal frost tolerance in newly emerging buds. Using this assay, we estimated genetic parameters and

Groundwater Depth Drives Carbon Pools and Population Dynamics in Deep‐Rooted Desert Plants of a Hyper‐Arid Ecosystem

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Groundwater depth shaped A. sparsifolia density and individual biomass. Carbon pools aided population persistence but couldn't offset deep groundwater's negative impact. Groundwater limits exceeded climate effects on desert vegetation persistence.

LWFBrook90.jl—Including Stable Water Isotopes in a Soil Vegetation Atmosphere Transport Model to Constrain Vertical Root Water Uptake Dynamics

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract In water‐limited ecosystems, soil water availability plays a pivotal role in determining the stress levels experienced by vegetation. Understanding the vertical distribution of roots and root water uptake (RWU) is essential for accurately predicting drought conditions using Soil Vegetation Atmosphere Transport (SVAT) models.

Divergent Trends in Insect Disturbance Across Europe's Temperate and Boreal Forests

Global Change Biology, Volume 31, Issue 11, November 2025.
Across temperate and boreal Europe, tree mortality caused by insects has risen during the 21st century, yet interactions among insect species and their host trees are complex. While mortality from wood‐boring insects in conifers has increased, defoliation caused by multiple moth species has declined.

Variation in the Molecular Phenotype of βglu‐1, an Insect Defence‐Related Beta‐Glucosidase Gene, in Two Transcontinental Picea Species

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Forest trees face threats from many insect pest species, underscoring the importance of understanding their defence mechanisms for survival. In a North American conifer species, Picea glauca, gene expression of βglu‐1 produces phenolic compounds (acetophenones) that defend against its insect defoliator, Choristoneura fumiferana. βglu‐1 is also

Distinct Molecular Biomechanical Mechanisms Inhibit Endosperm Cell‐Wall Weakening and Seed Germination at Cold and Warm Nonoptimal Temperatures

Plant, Cell &Environment, Volume 48, Issue 11, Page 8047-8067, November 2025.
ABSTRACT Temperature sensing to adjust developmental rates and phenological responses to different climatic environments is critical for plant survival. Population‐based thermal‐time threshold models predict linear relationships between temperature and, for example, seed germination rates (speed), but the mechanisms are not known.

Long‐term population dynamics of western tent caterpillars: History, trends and causes of cycles

Journal of Animal Ecology, Volume 94, Issue 10, Page 1922-1934, October 2025.
The length and in‐depth nature of this population study make it unique. It represents perhaps the most extensive monitoring of viral infection in a wild insect population. We have used laboratory and field experiments to test many hypotheses about mechanisms that potentially impact the dynamics of this cyclic species.

“Green pointillism”: detecting the within-population variability of budburst in temperate deciduous trees with phenological cameras

bioRxiv, 2019
Phenological cameras have been used over a decade for identifying plant phenological markers (budburst, leaf senescence) and more generally the greenness dynamics of forest canopies. The analysis is usually carried out over the full camera field of view,

High density SNP mapping and QTL analysis for time of leaf budburst in Corylus avellana L.

PLoS ONE, 2018
The growing area of European hazelnut (Corylus avellana L.) is increasing, as well as the number of producing countries, and there is a pressing need for new improved cultivars.
