Differences in leaf morphology between Quercus petraea and Q. robur adult and young individuals

Silva Fennica, 2008
The characters of Quercus robur and Q. petraea leaves are of main taxonomic value and the adult trees of both species can be distinguished on them. However, young individuals, mostly seedlings but also saplings, are told to be undistinguishable or ...

Artefacts Associated With Cryogenic Vacuum Distillation Do Not Compromise Plant Source Water Extraction From Soil and Xylem for Isotope Analysis

Ecohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Understanding the oxygen and hydrogen isotopic composition (δ18O and δ2H values, respectively) of plant source water is fundamental for tracing water uptake in ecohydrological studies. However, discrepancies between cryogenic vacuum distillation (CVD)‐extracted soil and xylem water and known plant source water δ18O and δ2H values continue to ...

Woods with Quercus petraea in Tuscany (Italy): a vegetation classification approach

Mediterranean Botany, 2018
In Tuscany (Italy), oak mixed woods with high cover values of Quercus petraea are rather infrequent but well documented within local and national phytosociological studies, even if, in the literature, not always analyzed and well characterized from the ...

EcoViz: a tool for visual analysis and photorealistic rendering of forest landscape model simulations

Ecography, Volume 2026, Issue 4, April 2026.
Simulation outputs from forest landscape models are complex, and tools for their visual analysis and effective communication are often limited. In this paper, we present EcoViz, a novel, open‐source visualisation platform designed to complement existing forest models by providing advanced 3D visualisation capabilities.

Importance of micromorphological characteristics of foliar and pollen grains for delimitation of Oak species in Iran [PDF]

تحقیقات جنگل و صنوبر ایران, 2011
Several species of oaks (Quercus spp.) grow abundantly in the Hyrcanian, Arasbaran and Zagros forests of Iran. Taxonomy of oaks is difficult because of it's immense size and wide distribution, heterophylly, hybridization and changes in morphological ...

Reconstructing post‐crisis recovery in the hinterlands of Constantinople: A high‐resolution first‐millennium CE pollen record from Lake Yeniçağa (NW Türkiye)

Journal of Quaternary Science, Volume 41, Issue 3, Page 520-539, April 2026.
ABSTRACT Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid‐1st millennium CE.

International Biological Flora: Loranthus europaeus*

Journal of Ecology, Volume 114, Issue 4, April 2026.
Loranthus europaeus is a deciduous hemiparasitic species native to Europe and western Asia, primarily parasitizing oaks. It forms xylem connections via haustoria, extracting water and nutrients while exhibiting high transpiration and low water‐use efficiency.

Variability in morphology of Microsphaera alphitoides Griffon et Maubl. in Poland

Acta Societatis Botanicorum Poloniae, 2011
The aim of this study was to verify descriptions of the morphology of the fungus responsible for powdery mildew on oak leaves of nursery seedlings and of young trees in forest stands. Infected, fully developed leaves from apical parts of stems of Quercus

Effects of tree diversity and mycorrhizal type on the spatio‐temporal variability of leaf litter production and quality in temperate forests

Journal of Ecology, Volume 114, Issue 4, April 2026.
This study tested whether combining high tree species richness with mixed mycorrhizal types (arbuscular mycorrhizal [AM] and ectomycorrhizal [EM] fungi) enhances productivity in forest ecosystems. Results did not support this: neither litter production nor nutrient traits benefited from mycorrhizal mixing.
