The ability of giant hogweeds to form monodominant communities and even pure monostands in invaded areas has been well documented. Understanding of the mechanisms leading to monostand formation can aid in determining the limitations of existing community ecology models and establishing an effective management plan for invasive species elimination. The aim of this observational study was to inve...
The coast of northern Primorye region, north of Peter the Great Bay has been sparsely studied in regards to its molluscan fauna, with just a few works reviewing the distribution of local mollusks. This work presents a survey of the shallow water heterobranch sea slugs currently occurring around Kievka Bay to Oprichnik Bay, Russia. Thirty-nine species of sea slugs were found in this study and th...
Abstract Background and objectives: Giardiasis is a parasitic infection of small intestine, with a worldwide distribution and the prevalence of Giardia in different parts of the world varies between 1 to 25%. Plants have the vast range of antimicrobial and antifungal activity that can be identified as alternative treatments for bacterial and parasitic pathogens, the same as Giardia. In this stu...
The Argentine ant, Linepithema humile, is a widespread invasive species characterized by reduced intraspecific aggression within introduced populations. To illuminate the mechanisms underlying nestmate recognition in Argentine ants, we studied the spatial and temporal fidelity of intraspecific aggression in an introduced population of Argentine ants within which intraspecific aggression does oc...
The major aromatic components of the essential leaf oil of the New Zealand lemonwood tree Pittosporum eugenioides are octyl acetate (33%), terpinen-4-ol (13%), decanol (6%) and (Z)-hex-3-enol (5%). These products are responsible for the characteristic Citrus-like aroma which is detected when the leaves are crushed, a phenomenon which provided the species with its common name. The major componen...
Skin status of produce is important in determining fruit quality. Sensory evaluation is often used to express this characteristic. A new method, atomic force microscopy (AFM), was proposed to denote the changes of skin status. Arithmetic roughness (Ra) and root mean square roughness (Rq) of ‘Jinxiu’ yellow peach (prunus persicu L. Batsch.) were analysed by AFM. The Ra and Rq values increased wi...
گیاهheracleum rawianium (گلپر معطر) یکی از گونه های بومی ایران متعلق به خانواده چتریان است. مطالعات و بررسی های کتابخانه ای نشان داد که این گونه از جنس heracleum تا کنون مورد مطالعه فیتوشیمیایی قرار نگرفته است. اندام های هوایی گیاه heracleum rawianium در مرداد 91 از کوه شابیل شهرستان مشکین شهر جمع آوری شده است. سه ترکیب فوروکومارینی آنجلیسین، آلوبرگاپتن، اسفوندین و دو ترکیب استرولی استیگمااسترو...
