Changes in European spring phenology

International Journal of Climatology, 2002
AbstractThe European phyto‐phenological database of the EU 5th Framework project ‘POSITIVE’ facilitated an examination of the rate and spatial pattern of changes in spring phenology across Europe. This database was collected, evaluated and composed from different national databases of Eastern and Western Europe covering the time period 1951–1998 ...

Integrating experiments to predict interactive cue effects on spring phenology with warming.

New Phytologist, 2022
Climate change has advanced plant phenology globally 4-6 days per °C on average. Such shifts are some of the most reported and predictable biological impacts of rising temperatures.

Spatial patterns and climatic drivers of leaf spring phenology of maple in eastern North America.

Science of the Total Environment, 2022
The resurgent frequency of extreme weather events and their strongly distinctive spatial patterns lead to a growing interest in phenology as an indicator of tree susceptibility. Using a long-term chronology of observations collected in situ, we predicted

Spring phenology is affected by fall non-structural carbohydrates concentration and winter sugar redistribution in three Mediterranean nut tree species.

Tree Physiology, 2021
Deciduous trees mostly rely on non-structural carbohydrates (NSC-soluble carbohydrates and starch) stored prior to dormancy to sustain both spring bloom and the initial phase of spring growth prior to the transition of leaves from sink to source.

Legacy effect of spring phenology on vegetation growth in temperate China

, 2020
Spring vegetation phenology is one of the most sensitive bio-indicators of the ongoing climate warming. Climate warming has substantially advanced spring phenological development and increased productivity of terrestrial ecosystems. However, the relative

Response of barren-ground caribou to advancing spring phenology

Oecologia, 2020
Phenological shifts are occurring in many ecosystems around the world. The capacity of species to adapt to changing phenology will be critical to their success under climate change scenarios. Failure to adjust migratory and reproductive timing to keep pace with the earlier onset of spring has led to negative demographic effects for populations of ...

Spring wood phenology responds more strongly to chilling temperatures than bud phenology in European conifers

Tree Physiology, 2023
Abstract A comparative assessment of bud and wood phenology could aid a better understanding of tree growth dynamics. However, the reason for asynchronism or synchronism in leaf and cambial phenology remains unclear. To test the assumption that the temporal relationship between the budburst date and the onset date of wood formation is ...

Divergent changes of the elevational synchronicity in vegetation spring phenology in North China from 2001 to 2017 in connection with variations in chilling

International Journal of Climatology, 2021
Mountain ecosystems are sensitive to climate change, and vegetation phenology provides one of the best signals to exemplify ecosystem responses to climate change.

Phenological Observations of Spring Geophytes in Quebec

Ecology, 1965
Observations were made in a sugar maple (Acer saccharum Marsh.) stand on the phenological response of three geophytes, Claytonia caroliniana, Erythronium americanum, and Trillium erectum, to solar radiation and temperature. The three species started development when the ground was partly covered with snow.
