The Plant Phenology Ontology: A New Informatics Resource for Large-Scale Integration of Plant Phenology Data

open access: yesFrontiers in Plant Science, 2018
Plant phenology – the timing of plant life-cycle events, such as flowering or leafing out – plays a fundamental role in the functioning of terrestrial ecosystems, including human agricultural systems. Because plant phenology is often linked with climatic

Estimating phenology and phenological shifts with hierarchical modeling

open access: yesEcology, 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
