This paper attempts to convey a flavor of the progress in Accelerator Mass Spectrometry
(AMS) since its initiation in 1977. During this period, AMS evolved into the most powerful …

Nonstructural carbohydrate reserves support tree metabolism and growth when current
photosynthates are insufficient, offering resilience in times of stress. We monitored …

Using new and published marine fossil radiocarbon (14C/C) measurements, a tracer
uniquely sensitive to circulation and air-sea gas exchange, we establish several …

This volume is a major revision and expansion of Taylor's seminal book Radiocarbon
Dating: An Archaeological Perspective. It covers the major advances and accomplishments …

Because the flowering and fruiting phenology of plants is sensitive to environmental cues
such as temperature and moisture, climate change is likely to alter community-level patterns …

Since the discovery of isotopes and the development of precise instrumentation capable of
measuring small differences in isotope abundances, there has been an interest in …

The sealed tube zinc reduction method for converting CO2 to graphite for AMS 14C
measurements was originally developed for rapid production of graphite in biomedical tracer …

Permafrost soils are an important reservoir of carbon (C) in boreal and arctic ecosystems.
Rising global temperature is expected to enhance decomposition of organic matter frozen in …

The allocation of nonstructural carbon (NSC) to growth, metabolism and storage remains
poorly understood, but is critical for the prediction of stress tolerance and mortality. We used …

Recent warming at high-latitudes has accelerated permafrost thaw in northern peatlands,
and thaw can have profound effects on local hydrology and ecosystem carbon balance. To …
