Is the grass always greener? Land surface phenology reveals differences in peak and season‐long vegetation productivity responses to climate and management

Ecology and Evolution, 2021
Vegetation phenology—the seasonal timing and duration of vegetative phases—is controlled by spatiotemporally variable contributions of climatic and environmental factors plus additional potential influence from human management.

Land surface phenology retrievals for arid and semi-arid ecosystems [PDF]

ISPRS Journal of Photogrammetry and Remote Sensing, 2022
Land surface phenology (LSP) plays a critical role in the regulation of photosynthesis, evapotranspiration, and energy fluxes. Significant progress has been made in extracting LSP information over large areas using satellite data, yet LSP retrievals remain a challenge over vast arid and semi-arid ecosystems because of sparse greenness, high variability

Land Surface Phenology in the Tropics: The Role of Climate and Topography in a Snow-Free Mountain

, 2017
Leaf phenology represents a major temporal component of ecosystem functioning, and understanding the drivers of seasonal variation in phenology is essential to understand plant responses to climate change.

A prognostic pollen emissions model for climate models (PECM1.0) [PDF]

Geoscientific Model Development, 2017
We develop a prognostic model called Pollen Emissions for Climate Models (PECM) for use within regional and global climate models to simulate pollen counts over the seasonal cycle based on geography, vegetation type, and meteorological parameters ...

Enviromics and Abiotic Enviromics: Enhancing Stress Biology and Plant Resilience Breeding

Advanced Science, EarlyView.
Environmental stressors are captured through high‐throughput envirotyping and integrated into an enviromic framework with genomic, transcriptomic, phenomic, and environmental data. AI/ML models enable prediction and guide marker‐assisted selection, genomic selection, genome editing, and gene pyramiding toward improved abiotic stress tolerance, yield ...

At the edge of change: Native Phragmites persistence and nonnative arrival along the dam‐regulated Colorado River

American Journal of Botany, EarlyView.
Abstract Premise The southwestern United States is at the forefront of nonnative Phragmites australis subsp. australis expansion. Native Phragmites australis subsp. americanus, likely in decline in North America, is ecologically and culturally important and of conservation interest. In the greater Grand Canyon region, the Glen Canyon Dam led to loss of
