Gravitational stress on germinating Pinus pinea seeds

Comptes Rendus. Biologies, 2003
In the germination of lipid-rich seeds, the glyoxylate cycle plays a control role in that, bypassing the two decarboxylative steps of the Krebs cycle; it allows the net synthesis of carbohydrates from lipids. The activity of isocitrate lyase, the key enzyme of the glyoxylate cycle, is an indicator of the state of seed germination ...

Analysis of lipophilic compounds in needles of Pinus pinea L. [PDF]

Annals of Forest Science, 2001
Monoterpene, sesquiterpene, neutral diterpene, fatty and resin acids were analyzed in needles of Pinus pinea. Together these compounds represent a mean of 6 mg g-1 of fresh needles. Sixty-five different compounds were identified. The main components were l-limonene (monoterpene), β-caryophyllene and germacrene D (sesquiterpenes), (11E,13Z)-labdadien-8 ...

Therrya fuckelii and other fungi on stems and branches of Pinus sylvestris following lightning damage

Acta Mycologica, 2013
The evidence-based hypothesis is presented that the stems and branches of Pinus sylvestris injured by lightning strikes are colonized first by Therrya fuckelii and successively by Diplodia pinea, Nectria fuckeliana, Hyaloscypha leuconica, Gremmeniella ...

Size mediated climate–growth relationships in Pinus halepensis and Pinus pinea

Trees, 2009
Functional processes in trees undergo changes as the tree size increases, which may affect the response of trees to environmental factors. We tested tree-ring response to climate in four groups of trees, including large and small Pinus halepensis and Pinus pinea trees using cluster, principal component (PC) and dendroclimatological analysis.

“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.

From glacial echoes to timber pathways: Climatic–historical drivers and timber‐trade influence on the phylogeography of Ips sexdentatus in the Basque Country

Agricultural and Forest Entomology, EarlyView.
Ips sexdentatus is expanding across southern Europe, attacking multiple Pinus species and showing the ability to colonize trees at early stages of decline. Genetic analysis of 668 individuals revealed 106 haplotypes, with Iberian populations as diversity hotspots, reflecting long‐term refugial persistence alongside more recent demographic expansion ...

Detecting social‐ecological fit in Natura 2000 governance and management: Evidence from LIFE projects focused on forest protected habitat types

People and Nature, Volume 8, Issue 8, Page 2521-2540, August 2026.
Abstract Protected areas represent complex social‐ecological systems that require governance and management approaches that valorise and enhance positive relationships between people and nature. This study analyses the alignment between social and ecological systems to detect the social‐ecological fit of projects focused on biodiversity conservation ...

Spiders in the mosaic: How habitat heterogeneity and structure drive local spider diversity in a Mediterranean forest

Ecological Entomology, Volume 51, Issue 4, Page 810-826, August 2026.
We assessed alpha‐ and beta‐diversity patterns of spiders across different forests and across vegetation layers (ground, shrub, low canopy) at local spatial scales across various Mediterranean forest types. Across forests, alpha‐diversity increased with habitat heterogeneity, which also drove beta‐diversity patterns across plots .
