Large-scale citizen science programs can support ecological and climate change assessments

open access: yesEnvironmental Research Letters, 2022
Large-scale citizen science programs have the potential to support national climate and ecosystem assessments by providing data useful in estimating both status and trends in key phenomena.

Land surface phenology detections from multi-source remote sensing indices capturing canopy photosynthesis phenology across major land cover types in the Northern Hemisphere

open access: yesEcological Indicators, 2022
Land surface phenology, which records the start of growing season (SOS) and the end of growing season (EOS), plays an essential part in reflecting plant photosynthesis and the response of carbon cycle in terrestrial ecosystems to climate change ...

Mapping Crop Phenology in Near Real-Time Using Satellite Remote Sensing: Challenges and Opportunities

open access: yes, 2021
Crop phenology is critical for agricultural management, crop yield estimation, and agroecosystem assessment. Traditionally, crop growth stages are observed from the ground, which is time-consuming and lacks spatial variability.

Monitoring nature's calendar from space: Emerging topics in land surface phenology and associated opportunities for science applications

open access: yesGlobal Change Biology, 2022
Vegetation phenology has been viewed as the nature's calendar and an integrative indicator of plant‐climate interactions. The correct representation of vegetation phenology is important for models to accurately simulate the exchange of carbon, water, and

Functional traits influence patterns in vegetative and reproductive plant phenology - a multi-botanical garden study.

open access: yesNew Phytologist, 2022
Phenology has emerged as key indicator of the biological impacts of climate change. Yet the role of functional traits constraining variation in herbaceous species' phenology has received little attention. Botanical gardens are ideal places to investigate

The European Phenology Network [PDF]

open access: yesInternational Journal of Biometeorology, 2003
The analysis of changes in the timing of life cycle-events of organisms (phenology) has been able to contribute significantly to the assessment of potential impacts of climate change on ecology. These phenological responses of species to changes in climate are likely to have significant relevance for socio-economic issues such as agriculture, forestry ...

Influences of Seasonal Soil Moisture and Temperature on Vegetation Phenology in the Qilian Mountains

open access: yesRemote Sensing, 2022
Vegetation phenology is a commonly used indicator of ecosystem responses to climate change and plays a vital role in ecosystem carbon and hydrological cycles. Previous studies have mostly focused on the response of vegetation phenology to temperature and

Dynamic Threshold of Carbon Phenology in Two Cold Temperate Grasslands in China

open access: yesRemote Sensing, 2021
Plant phenology, especially the timing of the start and the end of the vegetation growing season (SOS and EOS), plays a major role in grassland ecosystem carbon cycles.

Comparison of Vegetation Phenology Derived from Solar-Induced Chlorophyll Fluorescence and Enhanced Vegetation Index, and Their Relationship with Climatic Limitations

open access: yesRemote Sensing, 2022
Satellite-based vegetation datasets enable vegetation phenology detection at large scales, among which Solar-Induced Chlorophyll Fluorescence (SIF) and Enhanced Vegetation Index (EVI) are widely used proxies for detecting phenology from photosynthesis ...

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

open access: yesGeoscientific 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.
