Life history stability under climate change: a wildflower at the northern edge of its range
Stabilities of life history traits for a widespread native perennial wildflower, Rudbeckia laciniata L., are described for five populations near the northern edge of its range in North America. Theory proposes that such populations experience variable levels of stress as suitable abiotic conditions shift north or south from year to year, which ...
