Hello Everyone,

Please join us for a talk this *TODAY 2/22* by Chun Liu, 12-1pm in Room
SE2-302.

*Abstract:*

Soil erosion has been intensively studied with regards to the impact of
biogeochemical cycling of essential elements, especially elemental carbon
(C) in terrestrial ecosystems. Quantifying the C fluxes induced by erosion
within from terrestrial ecosystems is vital to accurately evaluate the
global C budget and predict the critical role of erosion on the C
sink/source on the Earth's climate system. Moreover, these results also
provide scientific basis on designing proper management practices in this
fragile ecosystem. In this talk we will explore differences in soil
properties from potential sources at eroding settings and then select the
appropriate tracers to identify the source of organic matter in sediments
at depositional settings (alluvial wedges retained by check dams) and
during rainfall processes in the outlet of catchment with different
management practices. In addition, the talk also argue the ecological
effect of eroded sediment organic carbon induced by soil erosion at the
catchment scale from an eco-geomorphologic perspective.



*Bio:*

Chun Liu is currently a visiting scholar working with Prof. Asmeret Asefaw
Berhe (ES) on soil biogeochemistry at UC Merced. He is also a Ph.D.
candidate at Hunan University (China) and State Key Lab of Soil Erosion and
Dryland Farming on the Loess Plateau (China), where he works with Prof.
Zhongwu Li. His research interests include soil erosion and source
identification of eroded organic carbon using multiple a fingerprint
approach, and he also estimate the relationships between land use change
and soil erosion on soil organic carbon and nitrogen stocks on slope and
catchment scales. So far, he has published 17 SCI papers, which of those
include first author papers 6 including one paper is awarded as ESI hot
paper (0.1%) and highly cited paper (1%) in agriculture science field
globally. It is his pleasure to discuss the topics of climate change, soil
science, human, and ecologic health.



When: Feb. 22, Thursday, 12pm – 1pm



Where: SE2-302



Coffee and treats will be provided, please bring your own mugs.



We look forward to seeing you,
