Four North American trees are becoming invasive species in Western Europe: Acer negundo, Prunus serotina, Quercus rubra, and Robinia pseudoacacia. However, their present and future potential risks of invasion have not been yet evaluated. Here, we assess niche shifts between the native and invasive ranges and the potential invasion risk of these four trees in Western Europe. We estimated niche c...
Цель работы - оценка степени расселения агрессивного чужеродного вида клена ясенелистного Acer negundo вдоль Транссибирской магистрали и определение основного вектора его инвазии. Инвентаризация «железнодорожной» флоры проводилась на Европейском, Уральско-Западносибирском, Байкальском, Амурском Уссурийском участках Транссиба в 2020-2021 гг. Заложены площадки размером 100 м2 следующих экотопах: ...
In a study of plants collected from the NW Iran, a specimen was identified as Bornmuellera cappadocica (DC.) Cullen & Dudley(Cullen 1965). This species and the genus Bornmuellera Hausskn. are a new record for Iran and the Flora Iranica area (Hedge & Rechinger 1968).
Chemical investigation of Vitex negundo seeds afforded four new lignans, including a phenylindene-type lignan, vitexdoin F (1), and three phenylnaphthalene-type lignans, vitexdoins G, H and I (2-4). Their structures were elucidated by detailed spectroscopic analyses on the basis of NMR, IR, and MS data. All compounds were evaluated for their anti-inflammatory and anti-osteoporotic activities, e...
