“Alien versus predator”: predatory effect of coccinellid Exochomus quadripustulatus on the scale insect Toumeyella parvicornis. An open‐field experimentation on the Pinus pinea of Rome

Insect Science, EarlyView.
The release of gravid Exochomus quadripustulatus females proved to be effective in containing Toumeyella parvicornis infestations on stone pine trees, under open‐field condition. The ladybugs caused a lower infestation level compared to the trees that did not receive any ladybugs during the observation season.

Disentangling Multitrophic Interactions: How Vegetation Cover, Wild Boar, Deer, and Predators Shape Rodents Activity and Acorn Dispersal

Integrative Zoology, EarlyView.
Vegetation cover promotes rodent activity and acorn dispersal, while wild boars exert a direct negative effect on mice. Conversely, deer and predators displayed no significant impact on rodent behavior. These results identify wild boars as the main disruptors of rodent‐mediated forest regeneration.

Long-Term Tree Regeneration of Fragmented Agroforestry Systems Under Varying Climatic Conditions

Frontiers in Ecology and Evolution, 2021
Iberian dehesas and montados are agroforestry systems protected by the European Habitats Directive due to high levels of biological diversity associated to their savannah-like structure. Tree scattering in dehesas, montados and other agroforestry systems

Conservation of holm oak (Quercus ilex) by in vitro culture

Mediterranean Botany, 2018
In vitro culture techniques are used to propagate tree species, as well as to conserve the species in the short and long term. In the present study, in vitro propagation and conservation of holm oak (Quercus ilex L.) were successfully achieved using juvenile material. Mature acorns were germinated under controlled conditions of moisture and temperature,

Sheep and cattle grazing regimes differentially affect ground beetle and ant communities in Mediterranean cork oak woodlands

Insect Conservation and Diversity, EarlyView.
Sheep and cattle grazing significantly shape ant and ground beetle species composition in Mediterranean cork oak woodlands, promoting higher diversity by increasing habitat heterogeneity. Ground beetles and ants reflect changes in grazing regimes, with sheep‐grazed areas showing the highest diversity, highlighting their utility in ecosystem monitoring.

Role of Seasonality and Fire in Regulating the Enzymatic Activities in Soils Covered by Different Vegetation in a Mediterranean Area

Applied Sciences, 2021
As they quickly respond to environmental conditions, soil enzymes, involved in nutrient cycles, are considered good indicators of soil quality. The Mediterranean area is a peculiar environment for climatic conditions and for fire frequency.

Acorn production in Spanish holm oak woodlands

Forest Systems, 2006
We present a review on the state-of-the-art of fruit prodution in Western Iberia woodlands («dehesas»), and particularly in Q. ilex (holm oak) «dehesas». This threatened ecosystem is of very high ecological and economical importance. Quercus sp. fruits (acorns) are essential for wildlife, and for pig fattening in «dehesas».

Perceiving Vegetation From Social Positions: Discourses on Plants in a Mediterranean Landscape

Sociology Lens, EarlyView.
ABSTRACT Understanding how vegetation is perceived, named and valued requires attention to the social positions from which these perceptions are produced. This article analyses vegetation perception from different social positions based on qualitative research conducted in the province of Jaén (Andalusia, Spain), a Mediterranean landscape characterized

Effects of Ecological and Dendrometric Parameters on Holm Oak Dieback in Chettaba Forest (Algeria)

Ekológia (Bratislava)
Quercus ilex is a tree that shows severe symptoms of oak decline. The mechanisms causing the decline of holm oak stands were studied on a network of eight observation plots installed in the Chettaba forest in Constantine’s southwestern area (Algeria ...
