EVALUATION OF ANTIOXIDANT ACTIVITY IN OAK LEAVES FROM THE REPUBLIC OF MOLDOVA EXPOSED TO HEAT STRESS [PDF]

open access: yesJournal of Plant Development
The total activity of antioxidant substances, oxidases, and catalases was evaluated in the leaves of three oak species – pedunculate oak (Quercus robur L.), sessile oak (Q. petraea Liebl.), and downy oak (Q. pubescens Willd.) from the Republic of Moldova,

Preference and performance of the gypsy moth cater­pillars on sweet chestnut and some oak species [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2010
In the establishment of mixed plantations, it is necessary to examine previously the relations of the principal and the admixed species and the most significant pests.

Osmotic adjustment in sessile oak seedlings in response to drought [PDF]

open access: yesAnnales des Sciences Forestières, 1997
Effets d'une sécheresse édaphique sur l'ajustement osmotique de jeunes plants de chêne. Des plants de chêne aessile âgés de 3 ans ont été soumis à des déficits hydriques se développant à deux vitesses (0,050 et 0,013 MPa·jour-1), obtenus en croisant deux niveaux d'irrigation et de compétition herbacée.

Response of diameter and height increment to thinning in oak-hornbeam coppice in the southeastern part of the Czech Republic

open access: yesJournal of Forest Science, 2016
The objective of this paper was to test the hypothesis that growth and soil moisture would increase after heavy thinning in seven years old oak-hornbeam coppice stand.

Chelation Drives Surface Substitution in Hybrid‐MXenes

open access: yesAngewandte Chemie International Edition, EarlyView.
We demonstrate ethylenediamine‐derived bidentate binding on Ti3C2 by controlled deprotonation of ─NH2 groups during reaction with Ti3C2Br2. XRD, XPS, ssNMR, STEM, DFT, and INS confirm the bidentate coordination and the superior stability of chelating modes, while AIMD reveals proton transfer and new surface imine–Ti bonding mode.

Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

COMPETITION BETWEEN SESSILE OAK SEEDLINGS AND COMPETING VEGETATION UNDER A SHELTERWOOD

open access: yesThe Journal "Agriculture and Forestry", 2021
The paper presents the results of research on competitive relations between sessile oak seedlings and the most important competing species of woody vegetation, as well as ground flora that grows under a shelterwood, after the preparatory-seed cut of the shelterwood cutting.

Edges as ecological filters: Asymmetrical orientation‐specific arthropod activity across forest boundaries

open access: yesInsect Science, EarlyView.
Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Response of sessile oak seedlings (Quercus petraea) to flooding: an integrated study [PDF]

open access: yesTree Physiology, 2006
Sessile oak is a species of great ecological and silvicultural importance in Europe; however, increased frequency and severity of flooding of forested areas pose a threat to its regeneration. We monitored water relations, root anatomical changes and the expression of two calmodulin genes (QpCaM) in sessile oak seedlings during a 14-day flooding ...

Processionary Moth Exposure in Europe: Toxic–Irritant and Immunoglobulin E‐Mediated Endotypes, Diagnosis and Management

open access: yesClinical &Experimental Allergy, EarlyView.
Most reactions are toxic–irritant, driven by epithelial injury and neuro‐inflammatory activation. IgE‐mediated allergy is less common but may cause immediate systemic reactions. Endotype differentiation guides diagnosis, risk stratification and management.
