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: ...

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...

Air temperatures in the arid western United States are predicted to increase over the next century. These increases will likely impact the distribution of plant species, particularly dioecious species that show a spatial segregation of the sexes across broad resource gradients. On the basis of spatial segregation patterns, we hypothesized that temperature increases will have a greater negative ...
