Along Ancient Migration Routes: Population Genetic Structure of Pedunculate Oak (Quercus robur) Across Central and Southeastern Europe

Diversity and Distributions, Volume 32, Issue 10, October 2026.
ABSTRACT Introduction and Aim Understanding the spatial distribution of intraspecific genetic variation in trees is essential for conservation and management of forest genetic resources. In pedunculate oak (Quercus robur), an economically and ecologically important European tree, southern and southeastern provenances are considered to be putative ...

Environmental Controls of Soil Inorganic and Organic Carbon Revealed Through Multivariate Analysis and Machine Learning in the Eastern Black Sea Region of Türkiye

Soil Use and Management, Volume 42, Issue 4, October‐December 2026.
ABSTRACT Understanding the controls of soil organic carbon (SOC) and soil inorganic carbon (SIC) in humid mountainous landscapes is challenging because of strong topo‐climatic and land‐use heterogeneity. This study assessed SOC, SIC, soil pH and the SIC/SOC ratio across 5964 km2 in the Eastern Black Sea region of Türkiye using 1310 topsoil samples ...

Rugged terrain, forest coverage, and insurgency in Myanmar

Conflict Management and Peace Science, 2023
This paper examines whether non-monotonic patterns exist between forest coverage and conflict processes in Myanmar. Specifically, the paper finds that forest coverage and civil conflict follow an inverted U-shaped relationship: conflict decreases at ...

Estimating Surface BRDF/Albedo Over Rugged Terrain Using an Extended Multisensor Combined BRDF Inversion (EMCBI) Model

IEEE Geoscience and Remote Sensing Letters, 2022
Land surface albedo is a crucial variable of earth energy budget and global climate change. Rugged terrain significantly impacts surface bidirectional reflectance distribution function (BRDF) and the subsequent albedo retrieval using satellite remote ...

A Uniform Model for Correcting Shortwave Downward Radiation Over Rugged Terrain at Various Scales

IEEE Transactions on Geoscience and Remote Sensing, 2023
Shortwave downward radiation (SWDR) plays a major role in the material and energy balance of the Earth’s climate system. However, most of the existing SWDR research and products assume that the surface is flat, ignoring the effect of topography.
