46. These oaks are typically classified according to the morphology of their leaves and acorns38. According to the classification system of Panahi47and Panahi et al.48,49,50,51, oaks of the Zagros forests are classified asQuercusbut in two sections,QuercusandCerris, in two...
Such fires would also have favored the proliferation of shade intolerant, fire-adapted oaks at the expense of shade-tolerant conifers. This would have increased the amount of oaks on the landscape and, critically, the acorns they produce (Dey 2002; Lear and Brose 2002; Klimaszewski-Patterson ...
(2008) when study- ing competitive dynamics of pines and oaks over time in Valais (Switzerland). Other studies also found tree growth and competition effects to be highly dependent on local climatic conditions (Gómez-Aparicio et al. 2011; Sánchez- Salguero et al. 2015; Madrigal-...
reasoned that while the wind is conveying the seeds of pines into hard woods, the squirrels and other animals are conveying the seeds of oaks and walnuts into the pine woods. He explained the successive alterations in tree populations (which he oversimplified a little here) in the following way...
It has long been observed that Périgord black truffles grow near tree roots, mainly those of oaks. In 1808, in the Vaucluse department at Saint-Saturnin-les-Apt, a Frenchman, Joseph Talon, sowed acorns at the foot of trees which had produced Périgord black truffles and then transplanted the...

Moreover, oaks are widely distributed from central Spain to Norway in Europe. The forest is of flat topography and lies at ~120 m above mean sea level (amsl). The climate is temperate, subject to the influence of both oceanic effects from the west and continental effects from the east. ...
Within oaks this process has been important, as it has shaped the current distributions of Q. petraea, Q. robur and their hybrids following post-glacial recolonization [62]. 5. Major Barriers to Hybridization Forest tree hybrid zones provide particularly interesting systems to examine the evolution...

The Sustainable Development Goals, developed in 2015 by the United Nations, are a set of 17 internationally agreed-upon goals to be reached by 2030. The forest sector stands out as an important player in tackling climate change and strengthening sustaina
