Climate change is putting forests at risk. Our research shows that a tree's water‐use strategy largely determines its growth across years: whereas one strategy performs better in normal years, the other is advantageous during drought. Trees grow best during drought when surrounded by neighbors whose water‐use strategies differ from their own ...

ABSTRACT The emergence and development of settlement mounds, also called tells, is of major interest for the analysis of socio‐economic transformations occurring in the lower Danube plain during the East European Chalcolithic period. In this context, the multiphase chronology and structural layout of tells are highly relevant indicators, but small ...

Classification of black soils, chernozems and chernozem-like soils
For ages Chernozems were recognized as the most fertile soils in Eurasia; the scientific study of soils started from Chernozems. However, the concept of the genesis of Chernozems evolved since the 19th century. This evolution was somewhat circular because many researchers returned back to the theories that stressed the importance of excessive moisture ...
