Long-Term Monitoring of Cork and Holm Oak Stands Productivity in Portugal with Landsat Imagery

open access: yesRemote Sensing, 2019
Oak stands are declining in many regions of southern Europe. The goal of this paper is to assess this process and develop an effective monitoring tool for research and management. Long-term trends of the Normalized Difference Vegetation Index (NDVI) were

Nonuniform temperature and light relationships of moss‐associated nitrogen fixation across climates

open access: yesNew Phytologist, EarlyView.
Light, moisture, and temperature response of nitrogen fixation in moss–cyanobacteria associations across five climatically contrasting ecosystems. Responses of nitrogen fixation in moss–cyanobacteria associations to light (μmol photons m−2 s−1), moss relative water content (%), and temperature (°C) across five climatically contrasting ecosystems ...

NT‐proBNP as a Predictor of Atrial Fibrillation Recurrence After Cryoballoon, Radiofrequency and Pulsed‐Field Ablation

open access: yesPacing and Clinical Electrophysiology, EarlyView.
Central Illustration: In a study investigating AF recurrence after PVI with RFA, CBA, and PFA, elevated NT‐proBNP emerged as a strong predictor of recurrence within the first year, outperforming other clinical measures. Color‐coded recurrence‐free survival probability charts derived from these data are proposed to support individualized clinical ...

Ecological and Biological Properties of Holm Oak (Quercus ilex L.) on the Island of Rab

open access: yesCroatian Journal of Forest Engineering, 2011
This paper deals with ecological and biological properties of Holm Oak trees (Quercus ilex L.) on the Island of Rab. Forest ecosystems are influenced by numerous local meteorological and climatic conditions. In spring 2006 four experimental plots (2x2 m),

Addressing post-transplant summer water stress in Pinus pinea and Quercus ilex seedlings

open access: yesiForest - Biogeosciences and Forestry, 2015
In central Spain, post-transplant water stress produces high seedling mortality after the first summer following outplanting. Our study was designed to determine whether survival and performance of outplanted stone pine (Pinus pinea) and holm oak ...

Tree—Open Grassland Structure and Composition Drive Greenhouse Gas Exchange in Holm Oak Meadows of the Iberian Peninsula

open access: yesAgronomy, 2020
Iberian holm oak meadows are savannah-like ecosystems that result from traditional silvo-pastoral practices. However, such traditional uses are declining, driving changes in the typical tree—open grassland structure of these systems.

Underground allies: Mycorrhizal flexibility facilitates orchid occurrence in post‐mining landscapes

open access: yesPlant Biology, EarlyView.
Epipactis helleborine associates with largely habitat‐specific fungal communities, with limited overlap between mining and woodland sites, yet maintains comparable genetic diversity across habitats. These results highlight the role of mycorrhizal flexibility in enabling habitat shifts and expanding ecological niches in human‐altered landscapes ...

Natural dynamics of holm oak-dominated forest stands in the National Park of Maremma, Tuscany

open access: yesForest@, 2009
Mediterranean sclerophyllous forests are coenoses worthy of great care because of their inherent bio-ecological value. The suspension of harvesting following the crisis of fuel wood market ruled the evolutive pattern of maquis over the last decades.

A Multi-Omics Analysis Pipeline for the Metabolic Pathway Reconstruction in the Orphan Species Quercus ilex

open access: yesFrontiers in Plant Science, 2018
Holm oak (Quercus ilex) is the most important and representative species of the Mediterranean forest and of the Spanish agrosilvo-pastoral “dehesa” ecosystem. Despite its environmental and economic interest, Holm oak is an orphan species whose biology is

Academic Resilience in Contexts of Inequality: Motivational and Self‐Efficacy Profiles of Disadvantaged High Achievers

open access: yesJournal of Adolescence, Volume 98, Issue 6, Page 1939-1956, August 2026.
ABSTRACT Introduction Socioeconomic disparities in academic achievement are well‐documented in France and emerge early in schooling. Yet, a subset of students from socioeconomically disadvantaged backgrounds attains high academic performance, challenging deterministic accounts of educational inequality.
