Assessing plant phenological changes based on drivers of spring phenology

open access: yeseLife
Abstract Understanding plant phenological responses to climate warming is crucial for predicting changes in plant communities and ecosystems but difficult with sensitivity analysis that is not linked to drivers of spring phenology. In this article, we present a new measure phenological lag to quantify the overall effect of phenological ...

Study on the changes in the temperature sensitivity of spring phenology of typical woody plants in the Qinling Mountains region

open access: yesFrontiers in Earth Science
To reveal the responses of plant phenology and climate change in the Qinling Mountains region, the phenological data of seven woody plants in the Qinling Mountains region from 1964 to 2020 were selected to analyze the patterns and characteristics of ...

Additions to the Acanthaceae of the Flora of Tropical East Africa: two new species from northern Kenya

open access: yesNordic Journal of Botany, EarlyView.
The new species Barleria kulalensis I.Darbysh. & Q.Luke and Dicliptera huriensis I.Darbysh. & Q.Luke are described and illustrated and their extinction risk is assessed provisionally. The former is based on Barleria sp. G of the Flora of Tropical East Africa (FTEA), with recent field observation and collection of this species from the foothills of ...

Relationships between flowering phenology and community composition in an experimental restoration of northwest prairies

open access: yesEcosphere
Phenology, the timing of biological life cycles, is a key indicator of global climatic change, with numerous studies showing that species' phenologies are shifting in response to climate change.

Differential impacts of soil hydrothermal properties on root and leaf phenology in cropland

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Root phenology is essential for ecosystem cycling and plant resource acquisition, yet its response to soil conditions is less understood than that of leaf phenology.

Mazus dabieshanensis sp. nov. (Mazaceae) from eastern China

open access: yesNordic Journal of Botany, EarlyView.
Mazus dabieshanensis, a newly described species endemic to the Dabieshan Mountains in eastern China, is illustrated and described. Molecular phylogenetic analyses based on nuclear and chloroplast DNA sequences consistently demonstrate that this new species forms a stable clade with other Mazus species characterized by a pubescent ovary. Morphologically,

The Impact of Urbanization on Spatial–Temporal Variation in Vegetation Phenology: A Case Study of the Yangtze River Delta, China

open access: yesRemote Sensing
The response of vegetation phenology to urbanization has become a growing concern. As impervious surfaces change as urbanization advances, the variation in vegetation phenology at the dynamic urbanization level was analyzed to significantly quantify the ...

A new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae)

open access: yesNordic Journal of Botany, EarlyView.
Revisions of herbarium collections reveal a new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae). Strophopappus comprises nine species occurring in South America, eight of which are endemic to Brazil. Currently, Vernonia riedeliana is treated as a synonym of Strophopappus bicolor.
