Estimating phenology and phenological shifts with hierarchical modeling

Ecology, 2023
AbstractClimate‐driven changes to phenology are some of the most prevalent climate change impacts, yet there is no commonly accepted approach to modeling phenological shifts. Here, we present a hierarchical modeling framework for estimating intra‐annual patterns in phenology (e.g., peak phenological expression) and analyzing interannual rates of change

The impact of vegetation phenology changes on the relationship between climate and net primary productivity in Yunnan, China, under global warming

Frontiers in Plant Science, 2023
Climate influences net primary productivity (NPP) either directly or indirectly via phenology. Therefore, clarifying the indirect effects of climate on NPP through phenology is of utmost importance.

RadialPheno: A tool for near‐surface phenology analysis through radial layouts

Applications in Plant Sciences, 2019
Premise Increasingly, researchers studying plant phenology are exploring novel technologies to remotely observe plant changes over time. The increasing use of phenocams to monitor leaf phenology, based on the analysis of indices extracted from sequences ...

Diverse and divergent influences of phenology on herbaceous aboveground biomass across the Tibetan Plateau alpine grasslands

Ecological Indicators, 2021
Indirect influences of phenology on productivity (e.g., phenology-functional traits-productivity) could exist due to close associations between phenology and plant functional traits, which may further result in the divergent responses of vegetation ...

Vegetation Phenology Influenced by Rapid Urbanization of The Yangtze Delta Region

Remote Sensing, 2020
Impacts of urbanization and climate change on ecosystems are widely studied, but these drivers of change are often difficult to isolate from each other and interactions are complicated.

The European Phenology Network [PDF]

International 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 ...

Relationship between tropical leaf phenology and ecosystem productivity using phenocameras

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.

Phenology

, 2022
The chapter titled Phenology: Climate change is shifting the rhythm of nature looks at how climate change is disrupting the life cycle patterns of plant and animal species, its consequences, and the need to address this issue by restoring ecological connectivity and biological diversity and most importantly, reducing greenhouse gas emissions.

Is timing of reproduction according to temperature sums an optimal strategy?

Ecology and Evolution, 2019
Temperature sums are widely used to predict the seasonal timing of yearly recurring biological events, such as flowering, budburst, and hatching. We use a classic energy allocation model for annual plants to compare a strategy for reproductive timing ...
