Variation characteristics of stable isotopes in precipitation and river water in Fenghuoshan permafrost watershed

Shui kexue jinzhan, 2012
Due to the complexity of the influence of freeze-thaw of active soil layer on water cycle,the hydrological observation is rare and difficult in permafrost watershed.In order to improve hydrological understanding in permafrost watershed,stable isotopes ...

Highly fractionated chromium isotopes in Mesoproterozoic-aged shales and atmospheric oxygen

Nature Communications, 2018
There is a long standing debate whether low atmospheric oxygen levels during the Mesoproterozoic Era hindered the evolution of crown-group animals. Here, the authors show with shale-hosted chromium isotopes that sufficient atmospheric oxygen for crown ...

Is What Comes out the Same as What Goes in? A Preliminary Investigation of the Isotopic Impacts of Digestion by Red‐Tailed Hawks (Buteo jamaicensis) and Eurasian Eagle Owls (Bubo bubo)

Ecology and Evolution
We investigated isotopic diet‐excreta offset (Δdiet‐excreta) for predatory birds, and the isotopic influence of bird digestion on consumed prey tissues.

Benthic Foraminiferal Oxygen Isotope Offsets Over The Last Glacial-Interglacial Cycle

, 2010
The oxygen isotope (?18O) offset between contemporaneous benthic foraminiferal species is often assumed constant with time and geographic location. We present an inventory of benthic foraminiferal species ?18O offsets from the major ocean basins covering

Triple oxygen isotopes

, 2019
© Huiming Bao 2019. Since the first discovery of isotopes of elements 100 years ago, the “detective” power of stable isotopes for processes that occurred in the past, and for elucidating mechanisms at the molecular level, has impressed researchers.
