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 ...

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.

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 ...

Plant Biology, EarlyView.The seasonal variation in inner bark width differed from that of xylem growth, indicating that xylem phenology cannot be reliably assessed without cellular observations. Abstract To better interpret continuous xylem growth measurements from dendrometers, we evaluated how the widths of developing xylem and phloem, along with seasonal trends in inner ...

Restoration Ecology, EarlyView.Abstract Introduction Intensified drought in the Mediterranean Basin poses challenges for conventional afforestation. Rainwater harvesting (RWH) is a climate‐adaptive solution that restores soil hydrological functions and buffers seedlings against drought in semiarid ecosystems.

Oikos, Volume 2026, Issue 9, September 2026.Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence. Particularly, generalist avian frugivores forage on them, co‐dispersing and co‐disseminating their seeds.
