Relationship between tropical leaf phenology and ecosystem productivity using phenocameras [PDF]

Frontiers in Environmental Science, 2023
Introduction: The interplay of water and light, regarded as the main driver of tropical plant dynamics, determines leaf phenology and ecosystem productivity.

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.

Identifying Leaf Phenology of Deciduous Broadleaf Forests from PhenoCam Images Using a Convolutional Neural Network Regression Method [PDF]

Remote Sensing, 2021
Vegetation phenology plays a key role in influencing ecosystem processes and biosphere-atmosphere feedbacks. Digital cameras such as PhenoCam that monitor vegetation canopies in near real-time provide continuous images that record phenological and ...

Leaf morphophysiology of a Neotropical mistletoe is shaped by seasonal patterns of host leaf phenology [PDF]

Oecologia, 2015
Several mistletoe species are able to grow and reproduce on both deciduous and evergreen hosts, suggesting a degree of plasticity in their ability to cope with differences in intrinsic host functions. The aim of this study was to investigate the influence of host phenology on mistletoe water relations and leaf gas exchange.

Leaf phenology as one important driver of seasonal changes in isoprene emissions in central Amazonia [PDF]

Biogeosciences, 2018
Isoprene fluxes vary seasonally with changes in environmental factors (e.g., solar radiation and temperature) and biological factors (e.g., leaf phenology).

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

Revista 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.

The Acadian Phenocam Network: Monitoring leaf and radial growth phenology to anticipate climate change impacts on forests

The Forestry Chronicle
Climate change is advancing leaf emergence in the spring and delaying leaf senescence in the fall. This extended leafing period may increase tree radial growth, with large potential impacts on wood supply and carbon sequestration, but empirical evidence ...

Solar Radiation Triggers the Bimodal Leaf Phenology of Central African Evergreen Broadleaved Forests

Journal of Advances in Modeling Earth Systems
Central African evergreen broadleaved forests around the equator exhibit a double annual cycle for canopy phenology and carbon uptake seasonality. The underlying drivers of this behavior are poorly understood and the double seasonality is not captured by

Larger temperature response of autumn leaf senescence than spring leaf‐out phenology [PDF]

Global Change Biology, 2018
AbstractClimate warming is substantially shifting the leaf phenological events of plants, and thereby impacting on their individual fitness and also on the structure and functioning of ecosystems. Previous studies have largely focused on the climate impact on spring phenology, and to date the processes underlying leaf senescence and their associated ...
