Dendrogeomorphology as a tool to depict hydrogeomorphic processes in the tropics

open access: yesRevista Cartográfica, 2022
Climatic and anthropogenic changes cause the deprivation of distinct ecosystems in Costa Rica, transforming climatic, ecological, and geomorphic conditions.

Art Adds Value to Ecological Field Courses: A Multi‐Year Case Study in Higher Education

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
This study presents Earth Projects, an interdisciplinary, place‐based field course that merges ecology and ecological art (eco‐art) to foster deeper engagement with environmental learning. Pre‐ and post‐survey comparisons show that incorporating eco‐art can strengthen students' emotional connections to their identities, disciplines, and place.

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.

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.

Climate change and fire alter biotic interactions and tree growth in high‐elevation forests

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract Climate change and shifting fire regimes have the potential to alter forest structure and tree growth dynamics in high‐elevation forests; however, the relative role of competitive and facilitative interactions in shaping postfire responses remains unclear.

Unravelling the evolution of the Frébouge polygenetic cone in Val Ferret (Mont Blanc Massif)

open access: yesBoreas, Volume 55, Issue 2, Page 454-475, April 2026.
Proglacial settings in the Alps are typically polygenetic, often characterized by a complex and discontinuous interplay between glacial, fluvial and gravitational processes. These processes yield high volumes of sediments, which usually exceed their transportation capacity.

A report on the examination of animal skin artefacts from the Bronze Age salt mines of Hallstatt, Austria [PDF]

open access: yes, 2006
The aim of this report is to describe the ten animal skin fragments and artefacts, and to discuss these in relation to the qualities and role of skins as a cloth technology in the Bronze Age. This includes the colour and texture, dimensions and thickness,
