Fire ash contains essential nutrients that play an important role in the forest by changing soil properties. The goal of this study was to investigate the physical and chemical properties of ash from burning litter and branches of Aleppo oak (Quercus infectoria Oliv.). Litter and dried branches with a diameter of less than 2 and 2-5 cm were collected under the canopy of eight oak trees in Dezli...
Oak wilt infection centers are initiated by overland spread of the causal fungus, Ceratocystis fagacearum (T. W. Bretz) J. Hunt, by insects (10). Sap-feeding beetles (Coleoptera: Nitidulidae) are considered a primary vector of the pathogen in the north central states (7,9). Successful transmission by sap-feeding beetles depends on several coexisting conditions, including (i) the availability of...
The fungus Raffaelea quercus-mongolicae is the causal agent of Korean oak wilt, a disease associated with mass mortality of oak trees (e.g., Quercus spp.). The fungus is vectored and dispersed by the ambrosia beetle, Platypus koryoensis Here, we present the 27.0-Mb draft genome sequence of R. quercus-mongolicae strain KACC44405.
ABSTRACT Background and objectives: Leishmania major is a flagellated parasitic protozoan that causes cutaneous leishmaniasis. Pentavalent antimony compounds are considered the first-line drugs in the treatment of cutaneous leishmaniasis. However, the use of these drugs is associated with numerous limitations and side effects. Theref...
introduction: land use change, deforestation, grazing, intentional and unintentional fire and invasive pests and diseases are all the major cause of damage to the zagros forest ecosystem. the green oak leaf roller (tortrix viridana l.) is one of the important pests of zagros forests. larvae of the pest significantly damage the oak forests with feeding on leaves and buds of different species of ...
Morphological variations of acorn among and within the groups of Quercus species were studied. A total of 617 acorns belonging to 14 species representing all 3 sections of Quercus L. (Fagaceae) in Turkey were examined in this study. Specimens were collected from 47 different populations over both Anatolian and Thrace part of Turkey. Principal component analysis was used to analyze the morpholog...
Acer rubrum L., A. saccharum Marsh., Quercus alba L. and Q. rubra L. seedlings subjected to soil and stem base heat treatments showed rapid declines in rates of transpiration and photosynthesis. Reductions in photosynthetic rate were partly attributable to mesophyll inhibition. Quercus seedlings were less able to maintain transpiration and photosynthesis after heat treatment than Acer seedlings...
Several squirrel species excise the embryo of acorns of most white oak species to arrest germination for long-term storage. However, it is not clear how these acorns counter embryo excision and survive in the arms race of coevolution. In this study, we simulated the embryo excision behavior of squirrels by removing 4 mm of cotyledon from the apical end of white oak acorns differing in embryo de...
