We present the first in vivo study of diatoms using atomic force microscopy (AFM). Three chain-forming, benthic freshwater species -Eunotia sudetica, Navicula seminulum and a yet unidentified species - are directly imaged while growing on glass slides. Using the AFM, we imaged the topography of the diatom frustules at the nanometre range scale and we determined the thickness of the organic case...

The Qinghai-Tibetan Plateau (QTP) is the highest and one of the most extensive plateaus in the world. Phylogenetic, phylogeographic, and ecological studies support plant diversifications on the QTP through multiple mechanisms such as allopatric speciation via geographic isolation, climatic oscillations and divergences, pollinator-mediated isolation, diploid hybridization and introgression, and ...

In the second part, we selected 50 native vascular plant taxa from 44 genera and 24 families. The 49 species one subspecies are belonging to Acanthophyllum C.A.Mey., Aegopodium L., Anabasis Anemone Antennaria Gaern., Aquilegia Armeria (DC.) Willd., Astragalus Atriplex Camphorosma Caragana Lam., Cardamine Chamaerhodos Bunge, Chesniella Boriss., Cicerbita Wallr., Crucihimalaya Al-Shehbaz, O'Kane ...
