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

International 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

Nordic 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,

Phenological control of vegetation biophysical feedbacks to the regional climate

Geography and Sustainability
Phenology shifts influence regional climate by altering energy, and water fluxes through biophysical processes. However, a quantitative understanding of the phenological control on vegetation’s biophysical feedbacks to regional climate remains elusive ...

Determination of sample size for a multinomial model coupled with the phenology model

Frontiers in Applied Mathematics and Statistics
Predicting the timing of phenological events is important in agriculture, especially high-revenue products. A project sponsored by USDA-ARS had the objective of adapting a previously developed model for estimating proportions of insects in different development stages as a function of temperature (degree) and time (days) for predicting bloom in almond ...
