UNLABELLED PREMISE OF THE STUDY Microsatellite markers in the genus Tilia were developed to investigate the genetic variation in T. platyphyllos and its relationship with T. cordata. • METHODS AND RESULTS Fifteen microsatellite markers were developed using a microsatellite enrichment protocol. Most loci show a high level of polymorphism in two T. platyphyllos populations from France. The n...

این تحقیق به منظور شناسایی گونه های مختلف جنس نمدار با استفاده از نشانگرهای ریخت شناسی، آناتومی و مولکولی انجام پذیرفت. به این منظور، ابتدا 13 رویشگاه نمدار در شمال ایران شناسایی و در هر رویشگاه، تا 15 پایه، با فواصل حداقل 100 متر از یکدیگر انتخاب شدند. از هر درخت نمونه های برگ، گل و میوه جمع آوری شد. در یافته های این تحقیق، هفت گروه متمایز ریختی میوه برای جنس نمدار در شمال ایران شناسایی شد. سط...

Since European settlement, hardwood dominated forests of the Upper American Midwest have undergone compositional changes due to fire suppression and changes in land use. It is not clear how these changes affect songbirds during spring migration. In 2009 and 2010, we quantified foraging behavior by migratory songbirds during spring migration and collected data on tree and sapling diversity in th...

The present research was conducted to find the influence of some topographic factors on distribution of large-leaved lime (Tilia platyphyllos Scop.) and its natural regeneration characteristics in "Vaz" forest (northern Iran). After identification of site and preparation of topography map, selective sampling method was carried out for tree inventory in plots. The sample plots were circular in 1...

abstract anti-nociceptive activity of aerial parts of phytolacca americana were investigated, using the hot plate method in mice. results of the present study showed that the aqueous methanolic extract of aerial parts of p. americana produced a statistically significant increase in pain threshold after 30 min, in comparison with the control, at adose of 190 mg kg-1 (p<0.001). the activity was c...

Periplaneta americana is the predominant cockroach (CR) species and a major source of indoor allergens in Thailand. Nevertheless, data on the nature and molecular characteristics of its allergenic components are rare. We conducted this study to identify and characterize the P. americana allergenic protein. A random heptapeptide phage display library and monoclonal antibody (MAb) specific to a t...

—This paper reviews population variation in Fraxinus americana (white ash) to determine whether intraspecific variation in various physiological traits affects growth and survival in F. americana and to correlate any intraspecific variation in F. americana with temperature or precipitation differences throughout the species range. Beginning in the 1980s, results from common garden studies indic...

Though the pathogenic significance and the reservoir of Ewingella americana have not been clarified, this organism has caused several pathogenic infections, especially in immunocompromised patients. We report a pneumonia in a patient with chronic renal failure, who had chronic rejection of transplanted kidney. E. americana was identified to be the pathogen of pneumonia with clinical symptoms an...
