To investigate the tree establishment and climatic signal present in tree-ring series, 104 increment core samples from 73 trees of Himalayan pencil cedar (Juniperus polycarpos) were collected. Ring-width sequences of trees are influenced by climatic factors as well as internal/external factors such ...

This paper introduces an important and powerful technique for studying the effects of climate change on tropical forests, the analysis of tree rings. Tree ring research is not new, but its wide application has been hampered by the common belief that tropical forest trees do not produce annual...

This paper describes the age of Himalayan cedar (Cedrus deodara) outside its natural home in the Himalayas. The paper records the oldest tree age of 477 years (AD 1536-2012) using dendrochronological methods. It is established that the Himalayan cedar forests earlier claimed to be natural in...

This paper presents a commentary on a study that correlated the amount of ray parenchyma in tree rings of Juniperus thurifera to climate [see New Phytologist (2013) 198, 486-495].

In this letter to the editor, certain issues on a recent report by Esper et al. [Supplementary material available on Science Online at www.sciencemag.org/cgi/content/full/295/5563/2250/DC1] on the use of low-frequency signals in long tree-ring chronologies for reconstructing past temperature...

This paper describes the tree-ring width chronology of an over-1000-year-old Himalayan pencil cedar (Cedrus deodara) growing in Himachal Pradesh, India. The chronology presented, based on the tree core samples from the collections, extends the earlier chronology further back by 438 years.
