Gross primary productivity is one of the most important factors in the carbon cycle of terrestrial ecosystems. With global warming increase, the frequent drought events and the specific response of regional vegetation to these changes, it is essential to identify and quantify the relationships between climatic and GPP data in arid region. In this study, the responses of gross primary productivi...

The data provide an overview of proteomic changes in red clover (Trifolium pratense L.) in response to cold acclimation and recurrent selection for superior freezing tolerance. Proteins were extracted from crowns of two red clover cultivars grown under non-acclimated or cold-acclimated conditions, and plants obtained from the initial genetic background (TF0) and from populations obtained after ...

Abstract. The surface morphology of lake ice remarkably changes under the combined influence thermal and mechanical forces. However, research on its interaction with climate is scarce. A large-scale linear structure has repeatedly appeared satellite images Chagan Lake in recent years. Geostationary Ocean Color Imager (GOCI), a 1 h revisit, Landsat 8 Operational Land (OLI), spatial resolution 30...

Climate risks are the inherent features of Earth's climate. The occurence of heat wave is one of these natural phenomena. Heat waves, one of the basic appearances of climate change, are very important because of frequency and damage of life and property, (Haddow et al, 2008). Frequency of heat wave occurence in recent years, is one of the aspects of climatic changes and extreme weather (Matthie...
