DH99a sediment core recovered at the center of Daihai Lake in north-central China was
analyzed at 4-cm intervals for pollen assemblage and concentration. The pollen record …

Using 14C dating, the life span and growth rate of Borneo ironwood (Eusideroxylon zwageri,

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 …

Two sediment cores recovered in the central part of Daihai Lake in north-central China were
analysed at 2-to 4-cm intervals for grain-size distribution. Grain-size distributions of the lake …

We present results that validate a new wet oxidation, stepped-combustion procedure for
dating “old” charcoal samples. An acid–base–wet oxidation (ABOX) pretreatment procedure …

Apparent 14C ages of the pre-bomb molluscan shells show new estimations of ΔR values
for the western Pacific including the East Sakhalin Current, Oyashio Current, Kuroshio …

Two sediment cores recovered in the central part of Daihai Lake in north-central China were
analysed at 2-to 4-cm intervals for total inorganic and organic carbon (TIC and TOC) …

A 2-m trench section at the desert/loess transition of north-central China was analyzed at 2-
cm intervals for grain-size distribution (Md, μm) and total organic carbon (TOC,%). AMS 14C …

Mycoheterotrophic plants depend entirely on fungal associations for organic nutrients. While
most mycoheterotrophic plants are associated with the mycorrhizal partners of surrounding …

Many tree species undergo large fluctuations from year to year in seed production, a
phenomenon known as masting. The resource budget model, based on the assumption that …
