Vegetation greenness and photosynthetic phenology in response to climatic determinants

open access: yesFrontiers in Forests and Global Change, 2023
Vegetation phenology is a key indicator of vegetation-climate interactions and carbon sink changes in ecosystems. Therefore, it is very important to understand the temporal and spatial variability of vegetation phenology and the driving climatic ...

All models of satellite-derived phenology are wrong, but some are useful: A case study from northern Australia

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2021
Satellite-derived phenology (or apparent phenology) is frequently used to illustrate changes in plant phenology (i.e. true phenology) and the effects of climate forcing. However, each study uses a different method to detect phenology.

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 ...

Phenology

open access: yesCurrent Biology
Flowers blooming, fungi fruiting, insects biting, fish spawning, geese migrating, deer calving; our consciousness is steeped in a seasonal calendar of nature's events. Phenology is the study of these recurring, seasonal life-history events, though nowadays this term is widely applied to the events themselves.

Responses of seasonal indicators to extreme droughts in southwest China [PDF]

open access: yes, 2020
Significant impact of extreme droughts on human society and ecosystem has occurred in many places of the world, for example, Southwest China (SWC). Considerable research concentrated on analyzing causes and effects of droughts in SWC, but few studies ...

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.

Plant phenology supports the multi-emergence hypothesis for ebola spillover events [PDF]

open access: yes, 2017
Ebola virus disease outbreaks in animals (including humans and great apes) start with sporadic host switches from unknown reservoir species. The factors leading to such spillover events are little explored.

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.
