Long-term persistence of experimental populations beyond a species' natural range.

Ecology 2021 Jun 9:e03432. Epub 2021 Jun 9.

Department of Biology, Queen's University, Kingston, Ontario, K7L 3N6, Canada.

Ecological experiments usually infer long-term processes from short-term data, and the analysis of geographic range limits is a good example. Species' geographic ranges may be limited by low fitness due to niche constraints, a hypothesis most directly tested by comparing the fitness of populations transplanted within and beyond the range. Such studies often fail to find beyond-range fitness declines strong enough to conclude that geographic range limits are solely imposed by niche limits. Read More
