The potential of stable carbon and nitrogen isotope analysis of foxtail and broomcorn millets for investigating ancient farming systems

open access: yesFrontiers in Plant Science, 2022
Foxtail and broomcorn millets are the most important crops in northern China since the early Neolithic. However, little evidence is available on how people managed these two crops in the past, especially in prehistory. Previous research on major C3 crops

Links between central Greenland stable isotopes, blocking and extreme climate variability over Europe at decadal to multidecadal time scales [PDF]

open access: yes, 2016
The link between central Greenland stable oxygen isotopes, atmospheric blocking frequency and cold temperature extremes at decadal to multidecadal time scales is investigated using observed and proxy data as well as model experiments.
