Links Between Carbon and Water Cycles in Northern Ecosystems: Constraints from Stable Isotopes [PDF]

open access: yes, 2006
High-latitude climate change will have an impact on the carbon and water cycles in northern ecosystems. Stable isotopes in these systems can serve as indicators of changes and feedbacks.

The main controls of the precipitation stable isotopes at Kathmandu, Nepal

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2020
Precipitation stable isotopes (2H and 18O) are adequately understood on their climate controls in the Tibetan Plateau, especially the north of Himalayas via about 30 years’ studies. However, knowledge of controls on precipitation stable isotopes in Nepal

Food webs in forest and pasture streams in the Waikato region, New Zealand: A study based on analyses of stable isotopes of carbon and nitrogen, and fish gut contents. [PDF]

open access: yes, 1997
Stable isotopes of carbon (C) and nitrogen (N) were studied in 11 stream communities in the Waikato region of New Zealand. From comparisons of mean d13C and d15N values, food webs in the shaded, forest streams were clearly based on allochthonous material
