Differential impacts of soil hydrothermal properties on root and leaf phenology in cropland

International Journal of Applied Earth Observations and Geoinformation
Root phenology is essential for ecosystem cycling and plant resource acquisition, yet its response to soil conditions is less understood than that of leaf phenology.

Herbivory in a changing climate—Effects of plant genotype and experimentally induced variation in plant phenology on two summer‐active lepidopteran herbivores and one fungal pathogen

Ecology and Evolution, 2022
With climate change, spring warming tends to advance plant leaf‐out. While the timing of leaf‐out has been shown to affect the quality of leaves for herbivores in spring, it is unclear whether such effects extend to herbivores active in summer.

Leaf position and phenological stage of branch for leaf analysis of Jatropha plants

, 2022
Leaf analysis is an important tool for prediction of nutritional disorders and evaluation of nutritional status of plants. This procedure only can be effective if samples are standardized regarding leaf position and phenological stage of the branch.

Utility of Leaf Area Index for Monitoring Phenology of Russian Forests

Remote Sensing, 2023
Retrievals of land surface phenology metrics depend on the choice of base variables selected to quantify the seasonal “greenness” profile of vegetation. Commonly used variables are vegetation indices, which curry signal not only from vegetation but also from the background of sparse foliage, they saturate over the dense foliage and are also affected by

A Novel Approach to Modelling Mangrove Phenology from Satellite Images: A Case Study from Northern Australia

Remote Sensing, 2020
Around the world, the effects of changing plant phenology are evident in many ways: from earlier and longer growing seasons to altering the relationships between plants and their natural pollinators.

Influence of meteorological conditions and crown defoliation on tree phenology in intensive forest monitoring plots in Slovenia

Acta Silvae et Ligni, 2014
Data from the forest monitoring programme in Slovenia were used to assess the relationship between tree phenology, crown defoliation and meteorological conditions in Fagus sylvatica, Quercus robur and Picea abies forests in the 2004-2013 period.

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

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 ...

Phenological Variation in the Composition of a Temperate Forest Leaf Tie Community [PDF]

Environmental Entomology, 2013
Arthropod communities in an array of temperate ecosystems follow similar phenological patterns of distinct compositional turnovers during the course of a season. The arthropod community inhabiting leaf ties is no exception. Many caterpillars build leaf ties, shelters between overlapping leaves attached together with silk, which are colonized ...

Reproductive stages in lowbush blueberry (Vaccinium angustifolium) occur earlier with increasing temperature

American Journal of Botany, EarlyView.
Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

Variability of phenology and fluxes of water and carbon with observed and simulated soil moisture in the Ent Terrestrial Biosphere Model (Ent TBM version 1.0.1.0.0) [PDF]

Geoscientific Model Development, 2015
The Ent Terrestrial Biosphere Model (Ent TBM) is a mixed-canopy dynamic global vegetation model developed specifically for coupling with land surface hydrology and general circulation models (GCMs).
