Acclimation of phenology relieves leaf longevity constraints in deciduous forests [PDF]

open access: yesNature Ecology & Evolution, 2022
Abstract Leaf phenology is key for regulating total growing season mass and energy fluxes. Long-term temporal trends towards earlier leaf unfolding are observed across Northern Hemisphere forests. Phenological dates also vary between years, whereby end-of-season (EOS) dates correlate positively with start-of-season ...

Deficiencies of Phenology Models in Simulating Spatial and Temporal Variations in Temperate Spring Leaf Phenology

open access: yesJournal of Geophysical Research: Biogeosciences, 2022
AbstractSpring leaf phenology and its response to climate change have crucial effects on surface albedo, carbon balance, and the water cycle of terrestrial ecosystems. Based on long‐term (period 1963–2014) in situ observations of budburst date and leaf unfolding date of more than 300 deciduous woody species from 32 sites across the temperate zone in ...

Leaf phenology, growth and photosynthesis in Pseudobombax munguba (Malvaceae) [PDF]

open access: yesRevista Ceres, 2019
Munguba (Pseudobombax munguba) is a tree often found in low-land forests of the Amazon region, and there is a paucity of data regarding its ecophysiology.

Turning a new leaf: PhenoVision provides leaf phenology data at the global scale

open access: yesApplications in Plant Sciences, EarlyView.
ABSTRACT Plant phenology dictates many aspects of community function and ecosystem dynamics. Yet, global phenology data are still limited, especially in areas lacking monitoring programs. Here we present a new data resource, PhenoVision–Leaf, which extends a computer-vision pipeline utilizing iNaturalist digital image vouchers to ...

Wet and dry extremes reduce arthropod biomass independently of leaf phenology in the wet tropics. [PDF]

open access: yesGlob Chang Biol, 2023
Warming temperatures are increasing rainfall extremes, yet arthropod responses to climatic fluctuations remain poorly understood. Here, we used spatiotemporal variation in tropical montane climate as a natural experiment to compare the importance of ...

Phenology as a strategy for carbon optimality: a global model [PDF]

open access: yesBiogeosciences, 2014
Phenology is essential to our understanding of biogeochemical cycles and the climate system. We develop a global mechanistic model of leaf phenology based on the hypothesis that phenology is a strategy for optimal carbon gain at the canopy level so that ...

Effects of the Simulated Enhancement of Precipitation on the Phenology of Nitraria tangutorum under Extremely Dry and Wet Years

open access: yesPlants, 2021
Plant phenology is the most sensitive biological indicator that responds to climate change. Many climate models predict that extreme precipitation events will occur frequently in the arid areas of northwest China in the future, with an increase in the ...

Improving Phenology Representation of Deciduous Forests in the Community Land Model: Evaluation and Modification Using Long‐Term Observations in China

open access: yesJournal of Advances in Modeling Earth Systems, 2023
Phenology is an important factor indicating environmental changes and regulates the variations of carbon, water, and energy exchange. However, phenology models exhibit large uncertainties due to limited understanding of its mechanisms.

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

open access: yesRemote 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 ...
