A study of seeds from alpine & lowland populations of Silene vulgaris shows that seed longevity has a genetic basis, but may show strong adaptive responses.
A study of Arenaria provincialis's (Caryophyllaceae) geographic range finds that despite its narrow distribution it has a high level of molecular variation.
Responses of high-mountain plant species to global change are highly influenced by the genetic background of the species, including genetic diversity or gene flow between populations. García-Fernández et al. study the...
