The biology of invasive alien plants in Canada. 9. Impatiens glandulifera Royle.
Impatiens glandulifera Royle (Himalayan balsam) is an invasive alien annual up to 3 m in height with showy flowers that are generally pink or purplish that can result in dense monotypic stands which prevent establishment of native plants and make streams vulnerable to erosion when the shallow-rooted plants die back.
TILLAGE EFFECTS ON WEED SEED RETURN AND SEEDBANK COMPOSITION
Populations of common lambsquarters and similar species may produce more seeds and persist in moldboard plow and chisel plow systems; these weeds may produce fewer seeds per unit area and be easier to manage in no-Till and ridge-till systems.
The biology of Canadian weeds. 112. Ulex europaeus L.
Gorse (Ulex europaeus L.) is a leguminous shrub native to western Europe and North Africa. During the past century it has greatly expanded its adventive range in Australia, New Zealand, Chile and…
Promotion of weed species diversity and reduction of weed seedbanks with conservation tillage and crop rotation
In practical terms, reduced tillage in combination with a good crop rotation may reduce weed density and expenditures on weed management.

Abstract Invasion by non-native plant species is one of the greatest threats to prairie, savanna, and oak woodland habitats of the Willamette Valley-Puget Trough-Georgia Basin (WPG) ecoregion.…
Adaptability of plants invading North American cropland
The biology of Canadian weeds. 105. Linaria vulgaris Mill.
Yellow toadflax, Linaria vulgaris Mill, is a weed of rangelands and agricultural crops that is now naturalized in all provinces and territories up to 60° northern latitude and beyond 2000 m altitude.

Climate change and weed adaptation: can evolution of invasive plants lead to greater range expansion than forecasted?
Assessment of the risk of invasive species owing to changing climate must incorporate evolutionary potential, as many invasive plant populations are likely to be in the process of developing adaptations that could lead to exponential population growth in the near future.
