Вторжение нового вида часто связывают с экологическими причинами, забывая при этом о генетическом разнообразии вида в основе его способности быстро адаптироваться в новых условиях среды обитания. Адаптивные процессы популяции в антропогенно трансформированных условиях могут осуществляться в историческом масштабе времени за небольшое число поколений. Амброзия полыннолистная (Ambrosia artemisiifolia L.) – агрессивный сорняк из Северной Америки, пыльца которого аллергенна. Нами проведены палеополинологические исследования истории появления и распространения амброзии на Дальнем Востоке России, а также выявлены ее консортные связи. Полученные результаты могут быть полезными в построении модели популяционной динамики амброзии полыннолистной для разработки системы ее уничтожения.

Abstract Potential effectiveness of harvest weed seed control (HWSC) systems depends upon seed shatter of the target weed species at crop maturity, enabling its collection and processing at crop harvest. However, seed retention likely is influenced by agroecological and environmental factors. In 2016 and 2017, we assessed seed shatter phenology in thirteen economically important broadleaf weed species in soybean [Glycine max (L.) Merr.] from crop physiological maturity to four weeks after physiological maturity at multiple sites spread across fourteen states in the southern, northern, and mid-Atlantic U.S. Greater proportions of seeds were retained by weeds in southern latitudes and shatter rate increased at northern latitudes. Amaranthus species seed shatter was low (0 to 2%), whereas shatter varied widely in common ragweed (Ambrosia artemisiifolia L.) (2 to 90%) over the weeks following soybean physiological maturity. Overall, the broadleaf species studied shattered less than ten percent of their seeds by soybean harvest. Our results suggest that some of the broadleaf species with greater seed retention rates in the weeks following soybean physiological maturity may be good candidates for HWSC.
