Leaf phenology amplitude derived from MODIS NDVI and EVI: Maps of leaf phenology synchrony for Meso‐ and South America [PDF]
Geoscience Data Journal, 2020 The leaf phenology (i.e. the seasonality of leaf amount and leaf demography) of ecosystems can be characterized through the use of Earth observation data using a variety of different approaches.

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

Effect of leaf phenology on the growth of rubber buddings
International Journal of Environment, Agriculture and Biotechnology, 2022 Rubber scion growth is the key step of rubber budding propagation. However, there is still a lack of systematic studies investigating leaf phenology effect on rubber scion growth. In this study, leaf phenology, stem diameter, plant height and the chlorophyll parameters were observed at six periods.

Turning a new leaf: PhenoVision provides leaf phenology data at the global scale
Applications in Plant SciencesABSTRACT 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 ...

Validation and application of the MERIS Terrestrial Chlorophyll Index. [PDF]
Climate is one of the key variables driving ecosystems at local to global scales. How and to what extent vegetation responds to climate variability is a challenging topic for global change analysis.

Shifting leaf fall phenology disrupts ecosystem function
Current BiologyLeaf litter fall and processing in temperate streams is one of the most pervasive resource subsidies and ecosystem functions globally.1,2,3 These subsidies are highly seasonally structured, yet their phenologies are shifting with climate change due to alterations of leaf senescence with global warming.4,5,6 As phenology and phenological changes are ...

Understorey light quality affects leaf pigments and leaf phenology in different plant functional types. [PDF]
Physiol Plant, 2022 Abstract Understory 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.

Leaf phenology as an indicator of ecological integrity
Ecosphere, 2023 AbstractClimate change leads to an increased frequency of severe weather events as well as stressful growing conditions. Together these changes may impact the resilience of ecosystems. To keep track of such effects, conservation managers monitor the “ecological integrity” or coherence of ecosystem processes, such as the cycling of carbon and water ...
