In terrestrial ecosystems, fungi are the major agents of decomposition processes and nutrient cycling and of plant nutrient uptake. Hence, they have a vital impact on ecosystem processes and the terrestrial carbon cycle. Changes in productivity and phenology of fungal fruit bodies can give clues to changes in fungal activity, but understanding these changes in relation to a changing climate is ...
The Forest Service's research on decay fungi and decay caused by fungi is done mainly in two research work units at the Forest Products Laboratory. One unit, the Center for Forest Mycology Research, performs biosystematic research on root-rot and products-rot fungi in the genera Armillaria, Phellinus, and Phlebia and maintains the culture collection supporting this research and other research o...
Characterization of structural woods in historical buildings has a great importance in technological study of applied details. Herein, seven historical buildings located in Alborz, Isfahan and eastern Azerbaijan provinces related to Safavid and Qajar periods have been assessed. Samplings were done from structural woods of the buildings. Samples were prepared, sectioned and evaluated by transiti...
General Practitioner (Rtd.), Westbury-on-Trym When we speak, loosely, of the structures we call mushrooms and toadstools, we refer to the fruiting bodies of fungi. Fungi, unlike green plants which absorb carbon dioxide from the air, obtain their nutrients by breaking down the tissues of wood, leaves, roots or, occasionally, animals, either living or dead. Essentially, fungi consist of ramifying...
the purpose of this study was to investigate how english language teachers in mashhad who teach students in the pre-university cycle perceived the impact of the efltee on their teaching. the target population was nearly all pre-university english language teachers in seven districts of mashhad in the scholastic year 2008/2009. a survey questionnaire which consisted of (36) likert type items, wa...
knowledge of the stand condition and the gradual replacement of tree species in different development stages and phases provide appropriate information related to the close to nature treatments. stem exclusion phase is one of the important development phases in the forest stands development. the aim of study was to analyze the characteristics of dead trees in the stem exclusion phase in the les...
Biscogniauxia species are known as fungal trunk pathogens on various tree in the world. During a survey of diseases fruit trees conducted Iran, branch dieback was observed almond Kerman province (in Southeast Iran). Evaluation symptomatic branches revealed wood discoloration cross-sections and presence fruiting bodies an ascomycete fungus their bark. A total 31 isolates were obtained, 13 recove...
hydrothermal treatment of wood material products with many interesting properties such as enhanced dimensional stability, lower equilibrium moisture content and increased biological durability. the effects of hydrothermal treatment on dimensional stability, oven dry density and water absorption of beech wood (fagus orientalis) naturally grown, has been studied in present research that extremely...
Most research on the carbon content of trees has focused on temperate tree species with little information existing for tropical tree species. Questions remain regarding how much carbon can be sequestered by various tree species and in different forest climatic zones. This study was designed to investigate the variation in carbon content of selected tropical tree species and compare the carbon ...
