3D Imaging of CRP and Ultrasonic Tomography to Detect Decay in a Living Adult Holm Oak (Quercus ilex L.) in Sardinia (Italy)

Applied Sciences, 2021
A field-integrated methodology using 3D ultrasonic tomography supported by close range photogrammetry (CRP) has been developed and evaluated as a tool to detect the presence and patterns of decay forms in a living adult holm oak (Quercus ilex L.) in an ...

Effect of Soil Water Content and Soil Texture on Phytophthora cinnamomic Infection on Cork and Holm Oak

Silva Lusitana, 2021
Phytophthora cinnamomi is an important soil borne plant pathogen, associated to decline of cork and holm oak stands in Iberian Peninsula. This decline results from a complex of biotic and abiotic interactions culminating in root infection.

Multi-temporal influence of vegetation on soil respiration in a drought-affected forest

iForest - Biogeosciences and Forestry, 2018
Aboveground plant activity influences fine roots and rhizosphere activity, which is reflected on soil respiration (SR). However, it is still unclear and poorly understood the nature of plant activity control over SR, especially under drought conditions ...

Evolution of Human Salivary Stress Markers during an Eight-Hour Exposure to a Mediterranean Holm Oak Forest. A Pilot Study

Forests, 2021
The current study analyses the evolution of different human stress markers during an 8 h exposure to a Mediterranean Holm oak forest. We conducted a pre-post study with thirty-one subjects in which saliva samples were collected before the exposure ...

Interactive effects of biotic stressors and provenance on chemical defence induction by holm oak (Quercus ilex)

Trees, 2021
Key Message The patterns of induced chemical defences in Quercus ilex leaves are specific to the biotic stress factor that causes them. Interactive effects between stressors depend on provenance.

Effectiveness of rodents as local seed dispersers of Holm oaks

Oecologia, 2007
In this study we assessed the effectiveness of rodents as dispersers of Quercus ilex in a patchy landscape in southeastern Spain. We experimentally followed the fates of 3,200 marked and weighed acorns from dispersal through the time of seedling emergence over three years.

A Contribution to the Knowledge of Composition and Classification of Holm Oak Forests in Istria

Croatian Journal of Forest Engineering, 2011
The forest vegetation of Istria is considered one of the most interesting vegetation types in the Republic of Croatia. This is confirmed by the presence of a large number of highly diverse forest communities occurring on the border between two completely
