Bayesian calibration of the Unified budburst model in six temperate tree species

International Journal of Biometeorology, 2011
Numerous phenology models developed to predict the budburst date of trees have been merged into one Unified model (Chuine, 2000, J. Theor. Biol. 207, 337-347). In this study, we tested a simplified version of the Unified model (Unichill model) on six woody species.

Climatic Warming, Spring Budburst and Forest Damage on Trees

The Journal of Applied Ecology, 1986
SUMMARY (1) If future C02-induced warming of 2 'C increased the incidence of warm springs, of the type that have occurred in Britain during this century, then warming would induce earlier blossoming and budburst in many temperate trees, with an increase in the risk of subsequent damaging frosts.

Genetic differentiation in the timing of budburst in Fagus crenata in relation to temperature and photoperiod

International Journal of Biometeorology, 2018
Climate change is expected to influence plant productivity particularly through changes in the timing of budburst. Nonetheless, knowledge about the intraspecific variation of the timing of budburst and its relationship with climate is insufficient for most tree species.

Phenological timings of leaf budburst with climate change in Japan

Agricultural and Forest Meteorology, 2008
Phenological timing of leaf budburst in plants is important for growth, since early budburst timing extends the growth period of the plant. We estimated the effect of climate change on the phenological budburst timing of four trees throughout four sites in Japan, a region with few studies on this topic.

Why Does Early-Season Herbivory Affect Subsequent Budburst?

Ecology, 1999
Delays in budburst in the year following herbivory have previously been attributed to a defensive response to early-season herbivory or localized resource deficien- cies (resource availability hypothesis) limiting bud development. We carried out field ex- periments to test the resource availability hypothesis as well as the crown architecture ...

Improving the budburst phenology subroutine in the forest carbon model PnET

Ecological Modelling, 2007
Abstract The timing of leaf expansion in spring and leaf senescence in fall determines growing season length; hence leaf phenology is important in modelling carbon production. Previous work monitoring net ecosystem exchange using eddy flux technology found phenological timing to be a key factor determining ecosystem carbon balance.

Stabilizing mechanisms enable dioecious trees to maintain synchrony in spring budburst under climate warming

New Phytologist
Climate change could reduce dioecious plant fitness if the phenology of males and females responds differently to temperature. However, the extent to which spring phenological responses to climate differ between sexes in wind‐pollinated dioecious trees ...

Predicted changes in the synchrony of larval emergence and budburst under climatic warming

Oecologia, 1992
The impact of climatic warming on the synchrony of insect and plant phenologies was modelled in the case of winter moth (Operophtera brumata) and Sitka spruce (Picea sitchensis) in the Scottish uplands. The emergence of winter moth larvae was predicted with a thermal time requirement model and the budburst of Sitka spruce was predicted from a ...

Assessment of Spatial and Temporal Trends Influencing the Occurrence of Frost After Budburst

Australian journal of grape and wine research
Background and Aims: The occurrence of frost after budburst is extremely damaging to the wine industry. This research aims to understand frost risk after budburst in Australian wine‐growing regions amid a changing climate, investigating the factors ...

Variation in seedling budburst phenology and structural traits among southwestern ponderosa pine provenances

, 2020
We used a common garden study to investigate genetic variation in spring budburst phenology, growth, and structural traits of ponderosa pine (Pinus ponderosa Lawson & C. Lawson var.
