Ecosystem responses to warming and watering in typical and desert steppes [PDF]

open access: yesScientific Reports, 2016
AbstractGlobal warming is projected to continue, leading to intense fluctuations in precipitation and heat waves and thereby affecting the productivity and the relevant biological processes of grassland ecosystems. Here, we determined the functional responses to warming and altered precipitation in both typical and desert steppes.

Ectoparasites on Meso-carnivores in the Desert-steppe of Mongolia

open access: yesMongolian Journal of Biological Sciences, 2018
Studying flea community structure on wild carnivores is important for identifying flea vectors for potential infectious diseases and providing information needed to design programs for human and wildlife health. We collected ectoparasites from 4 species of meso-carnivores in an arid Desert-steppe ecosystem of Mongolia.

Analysing the spatial variation of soil respiration during the early growing season of different grasslands in China [PDF]

open access: yesPeerJ
Background As one of the most essential vegetation types, grasslands play a vital role in the global carbon cycle. However, current researches on the spatial variation (SV) of soil respiration (Rs) in grasslands faces great uncertainties.
