Global cooling and/or Tibetan Plateau uplift have long been regarded as the principal drivers of late Cenozoic central Asian aridification and resulting widespread accumulation eolian deposits in eastern Asia. However, these two factors are unable to form large source areas fine-grained sediments enhancing deposition synchronously from northern Tibet North Pacific. Here we provide magnetostrati...

The article analyses data from the August Counts of 2018 and 2021, which covered 40 most important wetlands on Azov-Black Sea coast Ukraine. Of 106 wetland bird species recorded during censuses, 35 are listed in Red Data Book number them was about 50 thousand individuals or 7.6 % total counted birds: — 24.1 2021 25.8 individuals. Detailed information list sites for each can be found publication...

Abstract Numerical simulations indicate that extreme climate events (e.g., droughts, floods, heat waves) will increase in a warming world, putting enormous pressure on society and political decision-makers. To provide long-term perspective the variability of these events, here we use ~700 years tree-ring oxygen isotope chronology from Eastern Europe, combination with paleo-reanalysis data, to s...

Accurate chronology of climatic shifts is critical to understand the controls on landscape and species evolution. Unfortunately, direct dating continental climate change hindered by scarcity dateable terrestrial products evidencing shifts. Here we use ferruginous indurations from arid landscapes Nullarbor Plain in southern Australia constrain timing Plio-Pleistocene aridification realm. We pres...

The climatic transitions during the Miocene-Pliocene epochs had significant impacts on worldwide biological diversity and were associated with large turnovers of continental vegetation fauna. Previous studies have shown that late Miocene cooling aridification which was initiated 7 Ma reversed to warm conditions across Boundary ?5.3 Ma. Here, we present detailed orbital pacing Asian monsoon depo...

BACKGROUND The Central Asian flora plays a significant role in Eurasia and the Northern Hemisphere. Calophaca, a member of this flora, includes eight currently recognized species, and is centered in Central Asia, with some taxa extending into adjacent areas. A phylogenetic analysis of the genus utilizing nuclear ribosomal ITS and plastid trnS-trnG and rbcL sequences was carried out in order to ...
