Description
Mackenzie Urquhart-Cronish and co-authors asked in 2025 whether a fast spread leaves a plant with less gene variety. They studied an alpine flower in Garibaldi Provincial Park in Canada. The plant has spread onto land left bare as glaciers shrank over the past one hundred fifty years or so.
Many models say spread from a thin front line should raise drift and cut variety at the edge. The team tested gene markers across two areas of spread, comparing edge and older core sites. They found weak signs of more difference toward the edge and no sign of lower variety there. That hints that seeds did not come mainly from the front line during this spread.
