Reconstructing Climate From Coral Skeletal Banding: Statistical Effects of Replicating Cores and Observers

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Corals archive past ocean‐climate variability in their annual skeletal density bands, but the reliability of these records is dependent on precise and reproducible measurements. We assessed how variability among observers and cores affects coral growth measurements and their relationship with climate indices.

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

open access: yesArchaeometry, Volume 68, Issue 4, Page 620-632, August 2026.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

Southwestern (U.S.A.) Archaeological Tree-Ring Dating: 1930-1942

open access: yesBulletin of the History of Archaeology, 1997
Dendrochronology, the science of assigning precise and accurate calendar dates to annual growth rings in trees (Stokes and Smiley 1968), was the first independent dating technique available to prehistorians.

Impact of climate and environmental changes on forest ecosystem's productivity (case study: Galugah) [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2013
According to the results of the current research, a new approach in application of dendrochronology, using broadleaved tree rings, as main element of productivity, to evaluate forest ecosystem productivity, has been introduced.

Local Variability of Ice Core Ammonium and Black Carbon Records From Tunu and Summit, Greenland: Implications for Long‐Term Biomass Burning Reconstructions

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Paleoclimate reconstructions of wildfire using ice cores often rely on high‐resolution aerosol records of refractory black carbon (rBC) or ammonium (NH4+). The interpretation of such records, however, can be hindered by uncertainties related to long‐range atmospheric transport, spatial distribution and strength of emissions, as well as ...

Analysis of Site-dependent Pinus halepensis Mill. Defoliation Caused by ‘Candidatus Phytoplasma pini’ through Shape Selection in Landsat Time Series

open access: yesRemote Sensing, 2019
High levels of ‘Candidatus Phytoplasma pini’ have produced extensive forest mortality on Pinus halepensis Mill forests in eastern Spain. This has led to the widespread levels of forest mortality.

Addressing Biases in Ice Jam Observations by Integrating Multi‐Source Data in a Forested Fluvial Landscape, Southern Quebec

open access: yesRiver Research and Applications, Volume 42, Issue 6, Page 1188-1208, July 2026.
ABSTRACT Exhaustive long‐term and large‐scale ice jam records are scarce in most cold river environments. Many discrete events occur in small, sparsely populated river systems and are poorly represented in open‐source databases. These observation biases are transferred to predictive models of ice jams and the collective understanding of their formation

QUANTITATIVE COMMUNITY DESCRIPTION FROM CENTRAL KARAKORAM NATIONAL PARK (CKNP), GILGIT-BALTISTAN, PAKISTAN

open access: yesFUUAST Journal of Biology, 2011
A study was carried out to asses the communities and floristic composition of 32 stands of forest, shrubs and herbs from CKNP. On the basis of phytosociological analysis and maximum important value index, following 1 forest community, 3 pure stands and ...

Dendrochronological Investigations in Thailand

open access: yesIAWA Journal, 1995
Some of the first tree-ring chronologies from mainland Southeast Asia have been developed from Thailand, and a significant link between climate and tree growth has been suggested. Four chronologies from two species of pine (Pinus kesiya Royle ex Gordon and Pinus merkusii Jungh.
