Characterizing and forecasting the responses of tropical forest leaf phenology to El Nino by machine learning algorithms.

PLoS ONE, 2021
Climate change and global warming have serious adverse impacts on tropical forests. In particular, climate change may induce changes in leaf phenology.

Predicting Leaf Phenology in Forest Tree Species Using UAVs and Satellite Images: A Case Study for European Beech (Fagus sylvatica L.)

Remote Sensing, 2022
Understanding forest tree phenology is essential for assessing forest ecosystem responses to environmental changes. Observations of phenology using remote sensing devices, such as satellite imagery and Unmanned Aerial Vehicles (UAVs), along with machine ...

Understory light quality affects leaf pigments and leaf phenology in different plant functional types [PDF]

Physiologia Plantarum, 2019
AbstractUnderstory plant species take on different functional strategies, whereby some exploit periods of available light in springtime before the canopy closes, and others also benefit from sunlight later in autumn when the canopy opens again. These strategies involve understory species coordinating phenological events to pre-empt canopy leaf out and ...

Partitioning of three phenology rhythms in American tropical and subtropical forests using remotely sensed solar-induced chlorophyll fluorescence and field litterfall observations

International Journal of Applied Earth Observations and Geoinformation, 2022
The climatic drivers of leaf phenology and water stress regulation strategies in tropical/subtropical forest biomes are poorly understood on the continental scale.

Novel Representation of Leaf Phenology Improves Simulation of Amazonian Evergreen Forest Photosynthesis in a Land Surface Model

Journal of Advances in Modeling Earth Systems, 2020
Leaf phenology in the humid tropics largely regulates the seasonality of forest carbon and water exchange. However, it is inadequately represented in most global land surface models due to limited understanding of its controls.

Variation in phenology of Acacia senegal (L.) Wild. in relation to origin and ploidy level: Implications for climatic adaptation

Global Ecology and Conservation, 2022
Correct timing of phenology is crucial for the survival and growth of species in arid areas with long dry seasons. Nevertheless, knowledge on genetic variation and adaptive patterns in phenology in deciduous African dryland species is limited.

Leaf water relations reflect canopy phenology rather than leaf life span in Sonoran Desert trees

Tree Physiology, 2021
Abstract Plants from arid environments display covarying traits to survive or resist drought. Plant drought resistance and ability to survive long periods of low soil water availability should involve leaf phenology coordination with leaf and stem functional traits related to water status. This study tested correlations between phenology

Process-oriented models of autumn leaf phenology: ways to sound calibration and implications of uncertain projections [PDF]

Geoscientific Model Development, 2023
Autumn leaf phenology marks the end of the growing season, during which trees assimilate atmospheric CO2. The length of the growing season is affected by climate change because autumn phenology responds to climatic conditions.

The legacy effects of rubber defoliation period on the refoliation phenology, leaf disease, and latex yield

Plant Diversity, 2023
The leaf phenology of trees has received particular attention for its crucial role in the global water and carbon balances, ecosystem, and species distribution.
