The effect of pre-sowing priming with N-hexanoyl-L-homoserine lactone (C6-HSL) solution (300 mg/L) on acorn germination and morpho-phenological characteristics Quercus robur Q. rubra was studied under laboratory conditions. After priming, 93.4% acorns germinated that exceeded the control by 32.2%, while number sprouted increased within error limits 5% more than amounted to 90%. According morpho...
The maternal environment of a tree species can influence the development and resistance its offspring. Transgenerational induction is well known in plants but occurrence forest has been less reported. Quercus ilex L. (holm oak) widespread Mediterranean threatened by invasive Phytophthora cinnamomi Rands pathogen. P. on offspring infected Q. mother trees not studied. This study compared performa...
Abstract Planted woodland islets can provide seeds for restoring forest ecosystems in Mediterranean old fields lacking seed sources, but other factors than arrival also hinder the establishment of woody species. We experimentally examined affecting emergence, survival, growth and recruitment holm oak ( Quercus ilex ) seedlings juveniles from 25-year-old 100-m 2 planted a field. Wet springs summ...
Quercus robur L. exhibits not only a large inter-annual variability in seed production but also considerable among locations and individuals within the same year. The differences how individual trees populations of oaks invest acorn production, both terms yield size acorns quality, is interest ecologically economically. For this research we used data collected from harvesting which has been org...
Abstract Recurrent fires can impede the spontaneous recruitment capacity of pine forests. Empirical studies have suggested that this lead to a prolonged replacement forest by shrubland, especially if shrub species are pyrophytic. Model-based studies, however, post-fire succession under current climatic conditions will eventually tend towards dominance oaks high fire severity and recurrence. The...
The Edible Dormouse ( Glis glis ) is a small arboreal mammal that lives in deciduous forests much of Europe, the Iberian Peninsula being one southern limits its distribution. Some studies have shown this species uses strategy anticipatory reproduction, which means it adapts reproductive effort to seed production, such as beech mast and acorns, varies greatly from year year. anticipates future a...
Abstract This study aims to determine whether the application of cattle manure and associated bioturbation by dung beetles other invertebrates can increase oak seedling establishment in high biodiversity Mediterranean silvopastoral systems known as “dehesas”, which are comprised scattered oaks a grassland layer used for livestock rearing. A two-year was conducted representative dehesa southern ...
Corvids (crows, jays, magpies and nutcrackers) are important dispersers of large-seeded plants. Studies on captive or supplemented birds suggest that they flexibly adjust their scatter-hoarding behaviour to the context of social dynamics and relative seed availability. Because many corvid-dispersed trees show high annual variation in seed production, context-dependent foraging can have strong e...
