Tests for local adaptation in <i>Festuca rubra</i> based on results of likelihood ratio tests between generalized linear models in R for fitness estimated in reciprocal transplant experiment at native sites of regional origins in northern Finland, Faroe Islands, southern Finland and Spain for estimates of cumulative fitness and fitness components.

Significant differences supporting local adaptation (local has higher fitness than nonlocal) are marked with plus signs (+) and cases for local maladaptation (local has lower fitness than nonlocal) with minus signs (-).
