Oak Persistence in Mediterranean Landscapes: The Combined Role of Management, Topography, and Wildfires [PDF]

Ecology and Society, 2010
Mediterranean ecosystems have been shaped by a history of human and ecological disturbances. Understanding the dynamics of these social-ecological systems requires an understanding of how human and ecological factors interact.

Diversity of Volatile Emissions From Cork Oak: Quantity and Quality Vary Independently Across Its Range [PDF]

Ecology and Evolution
Knowledge of the intraspecific variability of volatiles produced by plants is central for estimating their fluxes from ecosystems and for understanding their evolution in an ecological and phylogenetic context.

Natural selection on cork oak: allele frequency reveals divergent selection in cork oak populations along a temperature cline [PDF]

Evolutionary Ecology, 2010
A recent study of population divergence at neutral markers and adaptive traits in cork oak has observed an association between genetic distances at locus QpZAG46 and genetic distances for leaf size and growth. In that study it was proposed that certain loci could be linked to genes encoding for adaptive traits in cork oak and, thus, could be used in ...

Characterization of the cork oak transcriptome dynamics during acorn development. [PDF]

BMC Plant Biol, 2015
Background: Cork oak (Quercus suber L.) has a natural distribution across western Mediterranean regions and is a keystone forest tree species in these ecosystems. The fruiting phase is especially critical for its regeneration but the molecular mechanisms

ChIP-Seq reveals that QsMYB1 directly targets genes involved in lignin and suberin biosynthesis pathways in cork oak (Quercus suber) [PDF]

BMC Plant Biology, 2018
Background Gene activity is largely controlled by transcriptional regulation through the action of transcription factors and other regulators. QsMYB1 is a member of the R2R3-MYB transcription factor family related to secondary growth, and in particular ...

Hybrids between cork oak and holm oak: Isoenzyme analysis [PDF]

, 2003
Hybrids between cork oak and holm oak occur in a large range of overlap between these two species in Portugal, and the subsequent crosspollination involving the hybrids and cork oak has been postulated to result in some of the worst cork-producing trees in Portugal.

Object-Based Land Cover Classification of Cork Oak Woodlands using UAV Imagery and Orfeo ToolBox

Remote Sensing, 2019
This paper investigates the reliability of free and open-source algorithms used in the geographical object-based image classification (GEOBIA) of very high resolution (VHR) imagery surveyed by unmanned aerial vehicles (UAVs). UAV surveys were carried out

Understory effect on tree and cork growth in cork oak woodlands

Forest Systems, 2018
Aim of study: Cork oak is one of the main forest tree species in Portugal that typically occurs in montado, where operational practices oriented to the tree, crop or animal management may influence several of the ecosystem components. This study aimed at

Effect of climate change on the spatial distribution and cork production of Quercus suber L., the risk of exclusion by the Aleppo pine expansion, and management practices to protect Q. suber habitat: A review

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2021
Climate change represents an important challenge for forest management and the silviculture of stands and it is known that climate change will have complex effects on cork oak forest ecosystems.

A Contingent Valuation-Based Method to Valuate Ecosystem Services for a Proactive Planning and Management of Cork Oak Forests in Sardinia (Italy)

Sustainability, 2023
The paper develops a model through a contingent valuation approach to support public authorities in the exploration and assessment of ecosystem services (ESs) generated by forest and woodlands (FOWLs). This approach is employed to the cork oak forests of
