Nitrogen (N) deposition is a key driver of global change with significant effects on carbon (C) cycling, species fitness, and diversity; however, its Mediterranean ecosystems are unclear. Here, we simulated N in an N-fertilization experiment 15N-labeled fertilizer montane evergreen holm oak forest, central Catalonia, to quantify short-term impacts leaf, leaf litter elemental composition, resorp...
Arbutus unedo L. is a Mediterranean species used for fruit production; it tolerant to drought and shows regeneration ability following forest fires. Mycorrhizal plants with Tuber borchii add resilience value. This study aims test the effect of quercetin on mycorrhizal synthesis between T. A. unedo. Two genotypes selected production hydric stress tolerance, were micropropagated synthesis, accomp...
The life cycles of two plant species in the Mediterranean chaparral, the evergreen Arbutus andrachne and the deciduous Rhamnus lycioides, were studied, as were the cycles of two stenophagous whitefly species that live on them, Trialeurodes lauri and Dialeurolobus rhamni, respectively. Trialeurodes lauri is univoltine, diapausing from June to March corresponding to the plant’s leaf dormancy. The...
The mineral, total amino acid, and sterol compositions of pollen collected by Apis mellifera L. were compared with the pollen of a plant consumed by Bombus terrestris (L.): Arbutus unedo L. This plant provides the predominant food resource for the main autumn generation of B. terrestris in southern France. Honey bees also forage on this plant, although only for nectar. The mineral composition o...
The lipophilic composition of wild Arbutus unedo L. berries, collected from six locations in Penacova (center of Portugal), as well as some general chemical parameters, namely total soluble solids, pH, titratable acidity, total phenolic content and antioxidant activity was studied in detail to better understand its potential as a source of bioactive compounds. The chemical composition of the li...
