Assessment of the Carbon Stock in Pine Plantations in Southern Spain through ALS Data and K-Nearest Neighbor Algorithm Based Models

Geosciences, 2019
Accurate estimation of forest biomass to enable the mapping of forest C stocks over large areas is of considerable interest nowadays. Airborne laser scanning (ALS) systems bring a new perspective to forest inventories and subsequent biomass estimation ...

Woody Vegetation Dynamics Beyond the Treeline: Identifying Limiting Processes and Their Tipping Points

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Illustration of temporal trends in Arctic and alpine woody vegetation under changing growth conditions (summer temperature and winter snowpack). Upper panel: example of shrub expansion in southern France (photograph included). Greening is detected via increasing NDVI (Normalized Difference Vegetation Index).

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

Archaeometry, 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 ...

Improvement of Remote Sensing-Based Assessment of Defoliation of Pinus spp. Caused by Thaumetopoea pityocampa Denis and Schiffermüller and Related Environmental Drivers in Southeastern Spain

Remote Sensing, 2019
This study used Landsat temporal series to describe defoliation levels due to the Pine Processionary Moth (PPM) in Pinus forests of southeastern Andalusia (Spain), utilizing Google Earth Engine. A combination of remotely sensed data and field survey data

Use of Aerial Laser Scanning to Assess the Effect on C Sequestration of Oak (Quercus ilex L. subsp. ballota [Desf.]Samp-Q. suber L.) Afforestation on Agricultural Land

Geosciences, 2020
Conversion of agricultural lands to forest plantations to mitigate rising atmospheric carbon dioxide (CO2) has been proposed, but it depends on accurate estimation of the on-site carbon (C) stocks distribution. The use of aerial laser scanning (ALS) data

Hydrodynamic parameters of floods and related bank erosion events indicated from tree rings and 2D hydrodynamic model for a small ungauged catchment (Sudeten Mts., Poland)

Ecological Indicators, 2021
Small mountain catchments usually lack hydrological monitoring and gauges. Therefore, in such areas, data on past flood and bank erosion are often missing, which makes assessing flood and erosion hazards very limited.

Dendrochronology and radiocarbon dating

, 2022
Both dendrochronology and radiocarbon (¹⁴C) dating have their roots back in the early to mid-1900s. Although they were independently developed, they began to intertwine in the 1950s when the founder of dendrochronology, A. E.

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

Bulletin 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.
