Comparative Ecological and Physiological Characteristics of the Response of Oak (Quercus robur L.) Seed Stands to Forest Growth Conditions

Лесной журнал
A comprehensive retrospective ecological and physiological analysis of tabular data on the dry mass of stands of the genus Quercus aged from 10–20 to 140–200 years has been carried out in order to convert them into quantitative indices of the functioning

Global urban expansion offsets climate-driven increases in terrestrial net primary productivity

Nature Communications, 2019
Robust estimates of either urban expansion worldwide or the effects of such phenomenon on terrestrial net primary productivity (NPP) are lacking. Here the authors used the new dataset of global land use to show that the global urban areas expanded ...

Global evidence on nitrogen saturation of terrestrial ecosystem net primary productivity

Environmental Research Letters, 2016
The continually increasing nitrogen (N) deposition is expected to increase ecosystem aboveground net primary production (ANPP) until it exceeds plant N demand, causing a nonlinear response and N saturation for ANPP.

A Novel Perfused Full‐Thickness Human Skin Microphysiological System for Modeling Injury, Regeneration, Tumor Pathophysiology, and Therapeutics Development

Advanced Healthcare Materials, EarlyView.
What if human skin could remain fully alive and functional outside the body for weeks? A New Alternative Method (NAM) based on a vascularized full‐thickness skin microphysiological system achieves precisely this, preserving native vasculature, resident immunity, and metabolic activity for up to three weeks, while faithfully recapitulating radiation ...
