Phenology

open access: yes, 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.

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

Color polymorphism in Anemone coronaria: Correlations with soil, climate, and flowering phenology

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Flower color polymorphism (FCP) is thought to be driven by multiple selection agents. Although widely associated with visual attraction of multiple pollinators, FCP is also often correlated with abiotic factors. We explored the links between abiotic conditions, flowering phenology, and FCP in the winter‐flowering geophyte Anemone ...

Modelling fire occurrence at regional scale. Does vegetation phenology matter? [PDF]

open access: yes, 2015
Through its influence on biomass production, climate controls fuel availability affecting at the same time fuel moisture and flammability, which are the main determinants for fire ignition and propagation.

Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

Quantifying the impacts of diverse vegetation-covered patterns on hillslope soil erosion: a case experiment of alfalfa-covered hillslopes

open access: yesFrontiers in Plant Science
IntroductionThe discrepancies in near-soil-surface hydrologic processes triggered by herbage spatial distribution pattern greatly influence the variation in hillslope erosion process. However, knowledge about the influence of herbage spatial distribution
