We present fossil pollen data and discuss their climatic interpretations from a 688-cm-long sediment core from Hurleg Lake, a freshwater lake located in the Qaidam Basin on the NE Tibetan Plateau, just beyond the northern limit of the East Asian summer monsoon influence. The reconstruction of the Holocene vegetation and climate history was aided by modern surface pollen analysis. The 14000-yr c...

Understanding how the aboveground net primary production (ANPP) of arid and semiarid ecosystems of the world responds to variations in precipitation is crucial for assessing the impacts of climate change on terrestrial ecosystems. Rain-use efficiency (RUE) is an important measure for acquiring this understanding. However, little is known about the response pattern of RUE for the largest contigu...

Arid grassland ecosystems have significant interannual variation in carbon exchange; however, it is unclear how environmental factors influence carbon exchange in different hydrological years. In this study, the eddy covariance technique was used to investigate the seasonal and interannual variability of CO₂ flux over a temperate desert steppe in Inner Mongolia, China from 2008 to 2010. The amo...

Rangeland degradation has been identified as a serious concern in alpine regions of western China on the Qinghai-Tibetan plateau (QTP). Numerous government-sponsored programs have been initiated, including many that feature long-term grazing prohibitions and some that call for eliminating pastoralism altogether. As well, government programs have long favored eliminating plateau pikas (Ochotona ...

The paper presents the analysis of genus Thymus flora South-East North Caucasus. Revealed total species, compiled an aspect , and conducted analysis's bioecological, geographical composition. In investigated territory, we have registered eight thymus distributed mainly in xerophilic types vegetation: steppe, friganoid, alpine, meadow-steppe, meadow societies.

We analyse new genomic data (0.05-2.95x) from 14 ancient individuals from Portugal distributed from the Middle Neolithic (4200-3500 BC) to the Middle Bronze Age (1740-1430 BC) and impute genomewide diploid genotypes in these together with published ancient Eurasians. While discontinuity is evident in the transition to agriculture across the region, sensitive haplotype-based analyses suggest a s...

Described from the steppe zones north of the Black Sea, Caucasus, and central Asia, Gryllotalpa stepposa Zhantiev was recently recorded from a few localities in Greece, R. Macedonia, and Bulgaria. In May 2015, several specimens were collected from Ivrinezu Mare in Romania, which suggested a continuous distribution area of the species, stretching from the central Balkans to central Asia. Thus, t...

Nowadays, the impact of anthropogenic activities on natural vegetation is constantly increasing, level threats raised, and newer risk factors are emerging. Recent trends in plant communities extremely pronounced, especially those listed Green Book Ukraine (GBU). Identifying such required for further development strategic tactical planning preservation restoration rare grass, shrub, subshrub ste...

• Late Eocene continental climate in Central Asia remains poorly understood. Tibetan lake deposits preserve records of palaeoenvironmental changes. Saline lakes east-central Tibet existed a cool and semi-arid desert-steppe. aridification caused shift Asia. palaeoclimate was primarily influenced by regional to global drivers. Ancient detailed Cenozoic environmental changes, providing information...
