Thirty-nine moss species occur on Kent Island, New Brunswick. Two-thirds of the moss species found on the island have mainly boreal ranges, which reflects the cool growing season and generally boreal character of the Bay of Fundy's vegetation. One species, Rhytidiadelphus loreus, has been recorded only once previously in the province. Most moss species showed distinctive habitat distributions. ...
Specific functional traits such as shade tolerance or leaf habits can enhance root growth dynamics and structure of planted seedlings in the understory forests. We assessed how low moderate light levels (17 33% full sunlight, mimicking after-thinning stocking) affect four late successional trees, three deciduous (Acer monspessulanum L., Quercus pyrenaica Willd Sorbus torminalis (L.) Crantz) one...
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...
