Towards a global leaf phenology model
2023Leaf phenology, often measured by the seasonal dynamics of leaf area index (LAI), is a key control on the exchanges of CO2 and energy between land ecosystems and the atmosphere. It is therefore also a key target process for dynamic vegetation models. However, there is no agreement on how leaf phenology should be modelled.

Seasonality and phenology alter functional leaf traits
Oecologia, 2012In plant ecophysiology, functional leaf traits are generally not assessed in relation to phenological phase of the canopy. Leaf traits measured in deciduous perennial species are known to vary between spring and summer seasons, but there is a knowledge gap relating to the late-summer phase marked by growth cessation and bud set occurring well before ...

Phenological variation of leaf functional traits within species
Oecologia, 2016A basic assumption of the trait-based approach in plant ecology is that differences in functional trait values are greater between species than within species. We questioned this assumption by assessing (1) the relative extent of inter- and intraspecific leaf trait variation throughout a complete growing season (phenological variation) in a group of ...

Ecological Significance of the Phenology of Leaf Abscission
Oikos, 1987The phenology of leaf abscission in different woody species with deciduous, marcescent and evergreen habits was studied over a complete annual cycle. Statistical treatment of the data permit the characterization of each species as a function of abscission time and of the length of the abscission period (estimation of the greater or smaller degree of ...

Plasticity to daylength of Iris pumila leaf phenological traits
Population Ecology, 2003AbstractPlastic responses to photoperiod of Iris pumila leaf phenological traits were investigated in two populations experiencing contrasting light conditions in the dune system at Deliblato Sands (44°48′ N, 38°58′ E; Serbia, Yugoslavia). The population “Dune” occupied an exposed area at the top and slope of a relatively large dune, and the population

Patterns of leaf phenology in forest understory
Canadian Journal of Botany, 1994Foliar phenologies of forest understory plants were categorized, and the distribution pattern of leaf habit was examined among different forest environments. Various patterns of foliar phenology were found, especially in herbaceous plants. In addition to the seasonal light regime controlled by the phenology of canopy trees, differences in the length ...

Hyperspectral indices to diagnose leaf biotic stress of apple plants, considering leaf phenology
International Journal of Remote Sensing, 2009Novel and existing hyperspectral vegetation indices were evaluated in this study, with the aim of assessing their utility for accurate tracking of leaf spectral changes due to differences in biophysical indicators caused by apple scab. Novel indices were extracted from spectral profiles by means of narrow-waveband ratioing of all possible two-band ...

A wheat canopy model linking leaf area and phenology
European Journal of Agronomy, 2005The accurate simulation of leaf area in wheat models is important because leaf area intercepts light and stores nitrogen, and the arrangement of leaves influences the transmission of foliar diseases and inter-species competition. In this paper, we report on the development and testing of a model that links a mechanistic phenological model that depends ...
