Macrophenology: insights into the broad-scale patterns, drivers, and consequences of phenology.

American-Eurasian journal of botany, 2021
Plant phenology research has surged in recent decades, in part due to interest in phenological sensitivity to climate change and the vital role phenology plays in ecology.

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

American 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 ...

Overestimation of the effect of climatic warming on spring phenology due to misrepresentation of chilling

Nature Communications, 2020
Spring warming substantially advances leaf unfolding and flowering time for perennials. Winter warming, however, decreases chilling accumulation (CA), which increases the heat requirement (HR) and acts to delay spring phenology.

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

American 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

Frontiers 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

Late spring freezes coupled with warming winters alter temperate tree phenology and growth.

New Phytologist, 2021
Spring phenology is advancing with warming but late spring freezes may not advance at the same rate, potentially leading to an increase in freezes after trees initiate budburst.

Reconstructing the evolutionary history of herbaceous crops through trait‐based ecology

American Journal of Botany, EarlyView.
Abstract Reconstructing the evolution of crop plants is fundamental to understanding their origins, ecological adaptations, and impacts on ecosystem processes. However, our understanding of crop evolution stems largely from archaeology and genetics, with less focus on a trait‐based ecological approach.

Using phenology data to improve control of invasive plant species: A case study on Midway Atoll NWR

Ecological Solutions and Evidence, 2020
1. Restoration of degraded lands often depends on knowledge of invasive plant species’ ecology coupled with well‐timed treatments to control them. Little is known about the reproductive phenology of Verbesina encelioides (golden crownbeard), which is a ...

Global Assessment of Cumulative and Time-Lag Effects of Drought on Land Surface Phenology

GIScience & Remote Sensing, 2022
Increased frequency and intensity of droughts under climate change will have a significant impact on land surface phenology, however, the drought-phenology interactions that are associated with complex temporal effects are not well understood. This study

Phenology of farmland floral resources reveals seasonal gaps in nectar availability for bumblebees

Journal of Applied Ecology, 2019
1.Floral resources are known to be important in regulating wild pollinator populations and are therefore an important component of agri‐environment and restoration schemes which aim to support pollinators and their associated services.
