The main characteristics of the Quercus pollination season were studied in 14 different localities of the Iberian Peninsula from 1992-2004. Results show that Quercus flowering season has tended to start earlier in recent years, probably due to the increased temperatures in the pre-flowering period, detected at study sites over the second half of the 20th century. A Growing Degree Days forecasti...
Evidence has shown that drought-induced crown dieback significant interaction with soil-plant water and nutrients relationships, but there isn’t sufficient knowledge of the connections in declining Persian oak (Quercus brantii) trees. To investigate relationships between leaf concentrations, content, soil concentrations moisture, one affected stands was selected. This stand located Shalam fore...
In this study three species of the genus Quercus section Erythrobulanus (Quercus coccinea, Quercus rubra, Quercus uelurina) were investigated. All occur together as canopy trees in forests of southern New England.

The present study models the effect of climate change on distribution Persian oak (Quercus brantii Lindl.) in Zagros forests, located west Iran. modeling is conducted under current and future climatic conditions by fitting machine learning method Bayesian additive regression tree (BART). For anticipation potential habitats for oak, two general circulation (GCMs) CCSM4 HADGEM2-ES representative ...
We measured 2188 oak trees (Quercus spp.) on the Hoosier National Forest in southern Indiana before and 1, 5, and 10 years after clear-cutting to determine the influence of parent tree age, diameter breast height, and site index on the probability that there was one or more living sprouts per stump: (i) 1 year after clear-cutting (sprouting probability) or (ii) that were competitively successfu...
