In Arnica montana L. (Asteraceae) two subspecies are described, A. montana subsp. atlantica (AMA), present only on the Iberian Peninsula and A. montana subsp. montana (AMM) with a very wide distribution area. The morphological differences between the

Plant diversity is decreasing mainly through anthropogenic factors like habitat fragmentation, which lead to spatial separation of remaining populations and thereby affect genetic diversity and structure within species. Twenty populations of the thre

Aim Species-rich dry grasslands have declined drastically in recent decades leading to spatial isolation of associated species. This can disrupt gene flow leading to genetic erosion, inbreeding and increased differentiation. Using Scabiosa canescens

Knowledge of within-species genetic diversity can improve effectiveness of conservation measures. These include the mitigation of extinction risks caused by habitat fragmentation, environmental change or diseases as well as site selection for in situ

We developed ten polymorphic microsatellite markers for the herbaceous species Scabiosa canescens Waldst. & Kit. The species is currently not assessed under the IUCN Red List but has been declining historically due to intensification in agriculture a
