Text 1
Mooseberry (Viburnum edule) plants are native to Alaska, where harsh conditions have historically impeded potential invasive species. As the boreal climate has warmed in recent decades, however, common knotgrass (Polygonum aviculare) plants have established themselves in Alaska. Previous research conducted in non-boreal ecosystems has documented warming-induced increases in summer temperatures benefiting invasive species more than native species.

Text 2
At a site near Fairbanks, Alaska, Christa Mulder and Katie Spellman tracked V. edule and P. aviculare, along with other native and invasive species, over several years. They observed that although average summer temperatures were substantially higher in some years of the study than in others, neither V. edule nor P. aviculare showed any significant variation in summer growth patterns from year to year.
