گونه Sorbus tiliaefolia به عنوان گونه جدیدی از شمال ایران نامگذاری و شرح داده میشود. این گونه به آسانی با داشتن برگهای قلبی نامتقارن، بدون لب مشخص و یا فاقد لبهای شانهای، همچنین چرمی بودن، وجود کرکهای پراکنده در سطح زیر برگها و اندازه تقریباً برابر طول و عرض برگها، کم و بیش کرکدار بودن دائمی شاخههای یکساله و گل آذینها، میوه کاملاً بیضی شکل، فرورفته بودن نوک آن و ریزان بودن کاسبرگها در طول رسی...
Sorbus torminalis L. Crantz is a colonizing tree species usually found at low density in managed European forests. Using six microsatellite markers, we investigated spatial and temporal patterns of genetic structure within a 472-ha population of 185 individuals to infer processes shaping the distribution of genetic diversity. Only eight young stems were found to be the result of vegetative repr...
Negative anticipatory contrast (NAC) corresponds to the suppression in consumption of a first rewarding substance (e.g., saccharin 0.15%) when it is followed daily by a second preferred substance (e.g., sucrose 32%). The NAC has been interpreted as resulting from anticipation of the impending preferred reward and its comparison with the currently available first reward [Flaherty, C.F., Rowan, G...
• Multidisciplinary education through collaborative laboratory and course work • Teamwork as the necessary framework for solving complex problems • Incorporation of state-of-the-art technologies throughout the curricula • Creation of continuous opportunities for technical communication. The Rowan program emphasizes these essential features in an eight-semester, multidisciplinary, engineering cl...

A number of potential anti-diabetic plants were identified through an ethnobotanical survey of the traditional pharmacopeia of the Cree of Eeyou Istchee (CEI-Northeastern Canada) used against symptoms of diabetes and their biological activity assessed by in vitro bioassays. Among these, Sorbus decora C.K.Schneid. (Rosacea) ranked highly and increased the transport of glucose in skeletal muscle ...
The dependence of vegetation attenuation on propagation geometry has been experimentally investigated at SHF band for isolated single trees. Two measurement heights (Trunk and Canopy) have been used in these experiments that involve three fully foliated trees, Common Whitebeam (Sorbus aria), Silver Maple (Acer Saccharinum) and Common Hazel (Corylus Avellana). Result shows that apart from freque...
The joint development of polymorphic molecular markers and paternity analysis methods provides new approaches to investigate ongoing patterns of pollen flow in natural plant populations. However, paternity studies are hindered by false paternity assignment and the nondetection of true fathers. To gauge the risk of these two types of errors, we performed a simulation study to investigate the imp...
