Drought legacy in mature spruce alleviates physiological stress during recurrent drought

open access: yesPlant Biology, EarlyView.
The slow recovery of leaf area in mature spruce following a long‐term drought alleviated physiological stress during recurrent drought. Abstract Forest ecosystems are facing severe and prolonged droughts with delayed recovery, known as “drought legacy”.

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.

New methods provide a 300‐year perspective on modern area burned in two wilderness areas of the southwest United States

open access: yesEcosphere, Volume 17, Issue 2, February 2026.
Abstract Climate change, expanding human ignitions, and increased fuels from fire exclusion are driving increases in area burned and fire severity in dry conifer forests of the western United States. Increasing area burned is occurring against the backdrop of a large fire deficit caused by over a century of fire exclusion.

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.

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.

Investigating Query by Committee and Inverse‐Distance Based Exploration for Active Learning as Learning Strategies: An Application in Wood Dating

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 1, Page 66-79, February 2026.
ABSTRACT Fourier transform infrared (FTIR) spectroscopy, a non‐destructive method, is capable of measuring changes in the major wood components cellulose, hemicellulose and lignin during degradation. Previous research evaluated the application of supervised machine learning based on molecular decay over specific preservation conditions, achieving a ...

Re-Bound Book Covers from the Island of Piirissaar, Estonia [PDF]

open access: yes, 2017
Old Believers’ service books from the Piirissaar house of prayer in Estonia were rescued from a fire and the damaged oak boards of the wooden covers of one of the books were dendrochronologically dated back to AD 1353.

Runoff Reconstructions and Future Projections Indicate Highly Variable Water Supply From Pacific Rim Water Towers

open access: yesAGU Advances, Volume 7, Issue 1, February 2026.
Abstract Anthropogenic climate change affects regional hydrological cycles and poses significant challenges to the sustainable supply of freshwater. The Central China water tower (CCWT) is the key source region feeding the Yangtze and Yellow Rivers, and its runoff is indispensable for the surrounding mega‐city clusters. Here we present a reconstruction

Assemblage, archive, and ancestor: Developing more‐than‐human historical geography with salmon

open access: yesGeographical Research, Volume 64, Issue 1, February 2026.
This paper interrogates recent geographic literature on the more‐than‐human archive and argues that there needs to be more specificity when conceptualising and researching the more‐than‐human. It then answers this call for specificity by theorising three modes of more‐than‐human historical geography that are developed through empirical encounters with ...
