Global warming scenarios have made the understanding of carbon sequestration changes in the stems of forest trees important. However, there is a lack of understanding about climate change's effects on the wood density of hardwood, which is a crucial indicator of wood biomass. Therefore, we...

The present study aimed to explore the dendroclimatic potential of three conifer species, viz. Taxus cuspidata, Abies koreana, and Pinus koraiensis, in the subalpine zone in the Republic of Korea. The tree-ring δ18O chronologies were analyzed for the last 50 years and were found to be well...

The so-called Millennium Eruption of Baitoushan Volcano is one of the largest of the Common Era but its date has been uncertain. Recently, Oppenheimer et al. (2017) reported the eruptive year as late AD 946 using a new method called carbon-14 spike matching. However, it is necessary to verify their ...

The oxygen isotope ratio (δ18O) of tree-ring cellulose provides a valuable climatic record with an annual timescale. In Japan, the cellulose δ18O records have been accumulated over the past decade. However, no long-term records have been reported for the southern subtropical island, Okinawa-jima,...

This paper discusses a dendrochronological approach to studying works of art associated with Shintoism, an indigenous religion of Japan. Chronological studies of Shinto artwork are, by comparison, lagging behind the studies on artwork associated with the other primary religion of Japan, Buddhism....

The spring Arctic Oscillation (AO) significantly affects the subsequent summer rainfall in the East Asian summer monsoon (EASM) region, and analysis of meteorological data indicates this teleconnection strength varied on interdecadal timescales during the late 20th century. Tree-ring records may be ...

Tree age derived from annual-ring counts provides fundamental information on forest stands and individual trees in temperate forests. However, discontinuous growth in the trunk may cause inaccuracies in annual-ring counts, and the effect of radial growth rate and interspecific differences on...

Oxygen isotope ratios (δ18O) of tree-ring cellulose are a novel proxy for summer hydroclimate in monsoonal Asia. In central Japan, we collected 67 conifer wood samples, mainly Chamaecyparis obtusa, with ages encompassing the past 2600 years. The samples were taken from living trees, archeological...
