Phenological response to climatic change depends on spring warming velocity

Communications Earth & Environment
Climatic change is dramatically altering phenology but generalities regarding tempo and mode of response remain limited. Here we present a general model framework incorporating spring temperature, velocity of spring warming, and species’ thermal ...

The Impact of Smoothing Techniques on Vegetation Phenology Extraction: A Case Study of Inner Mongolia Grasslands

Agronomy
The selection of data smoothing methods is one of the key steps in extracting land surface phenology parameters from time-series remote sensing data. However, existing studies often use default parameters for denoising the time-series data, neglecting ...

Unraveling cryptic lineages in Jatropha nana: phylogenetic evidence supports species status for J. benghalensis (Euphorbiaceae)

Nordic Journal of Botany, EarlyView.
The taxonomic framework of the genus Jatropha (Euphorbiaceae) is well established, but its geophytic species present significant classification challenges. These difficulties arise from species complexes, cryptic traits, and high environmental and phenotypic variability.

Aster tongrenensis (Asteraceae), a remarkable new species from Guizhou, China

Nordic Journal of Botany, EarlyView.
Aster tongrenensis (Asteraceae), a remarkable new species from Guizhou, China, is here described, illustrated and compared with related taxa based on integrated evidence from morphology, micromorphology and molecular phylogeny. Morphological and micromorphological observations indicate that A. tongrenensis is most similar to A.

Incorporating climate data with machine learning can improve rice phenology estimation

Environmental Research Letters
Crop phenology provides essential information for crop management and production. Satellite-based methods are commonly used for phenology estimation but still struggle to capture interannual variations of phenological events.

Taxonomic treatment, geographic distribution and preliminar conservation status of Croton sect. Barhamia subsect. Barhamia (Euphorbiaceae) in Brazil

Nordic Journal of Botany, EarlyView.
The genus Croton (Euphorbiaceae) is an exceptionally megadiverse genus, encompassing roughly 1200 species that are predominantly distributed across tropical regions globally. For the New World, the genus is organized into three subgenera (Adenophylli, Geiseleria and Quadrilobi) and 31 sections, with C. sect. Barhamia standing out with its approximately

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

Frontiers 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 ...
