“…due to the loss of climatically suitable habitats (Maclean & Wilson, 2011). However, disentangling the impact of multiple factors on extinction processes is very difficult and causes other than climate change may influence species decline on rear edges (Maurice, Colling, Muller, & Matthies, 2012;Munilla, Diez, & Velando, 2007). The extinction risk of the studied plants was generally higher between 1950 and 1980 than after 1980, although the overall pattern (most extinctions in WH) remained the same.…”

“…The weak influence of management and habitat characteristics in our study to Arnica 's fitness contrasts with their previously identified effects. Many studies that highlight the importance of management included diverse management intensities, which ranged from more intensively managed to fallow sites, in which A. montana has either bad or advantageous growing conditions (e.g., Kahmen & Poschlod, 1998⁠; Maurice et al, 2012). Instead, we incorporated only management categories according to agri‐environmental scheme regulations, which are considered to be beneficial for the species, for example, by favoring the plants’ seed maturation, and effective in its habitat conservation (Schwabe et al, 2019).…”

“…In addition, it is reported that slug herbivory acts as a limiting factor for Arnica 's geographical range toward lowland sites by causing considerable leaf damages (Bruelheide & Scheidel, 1999). Overall threats for A. montana across elevations are isolation and small‐sized populations with low genetic diversity (Duwe, Muller, Borsch, & Ismail, 2017), because the reproductive and genetic fitness of Arnica populations are strongly influenced by population size and its demographic structure (Kahmen & Poschlod, 2000; Maurice, Colling, Muller, & Matthies, 2012; Maurice, Matthies, Muller, & Colling, 2016). However, elevation and linked climatic factors as well as management are considered as equally important factors that influence the vegetative and generative performance of A. montana individuals because environmental conditions and biotic interactions are expected to become more suitable at higher elevations (Mardari et al, 2019).…”

Summer aridity rather than management shapes fitness‐related functional traits of the threatened mountain plant Arnica montana

Semi‐natural mountain grasslands are increasingly exposed to environmental stress under climate change. However, which are the environmental factors that limit plants in these grasslands? Also, is the present management effective against these changes? Fitness‐related functional traits may offer a way to detect changes in performance and provide new insights into their vulnerability to climate change. We investigated changes in performance and variability of functional traits of the mountain grassland target species Arnica montana along a climate gradient in Central German low mountain ranges. This gradient represents at its lower end climate conditions that are expected at its upper end under future climate change. We measured vegetative, generative, and physiological traits to account for multiple ways of plant responses to the environment. Using mixed effects and multivariate models, we evaluated changes in trait values among individuals as well as the variability of their populations in order to assess performance under changing summer aridity and different management regimes. Fitness‐related performance of most traits showed strongly positive associations with reduced summer aridity at higher elevations, while only specific leaf area and leaf dry matter content showed no association. This suggests a higher performance level at less arid montane sites and that the physiological traits are less sensitive to this climate change factor. The coefficient of variation of almost all traits declined steadily with decreasing site aridity. We suggest that this reduced variability indicates a lower environmental stress level for A. montana toward its environmental optimum at montane elevations, especially because the trait performance increased simultaneously. Surprisingly, management factors and habitat characteristics had only low influence on both trait performance and variability. In summary, summer aridity had a stronger effect to shape the trait performance and variability of A. montana under increased environmental stress than management and other habitat characteristics.

“…Arnica montana L. (Asteraceae, mountain arnica, wolfs' bane) is a perennial, facultative apomictic species (Yankova-Tsvetkova et al 2016), predominantly self-incompatible, insect pollinated which reproduces sexually with seeds and vegetatively with short rhizomes (Luijten et al 1996(Luijten et al , 2000. A. montana grows on acidic grass-and shrublands and is distributed from the Iberian Peninsula to the Ukraine (Maurice et al 2012). Bolos y Vayreda (1945) distinguished two subspecies, A. montana subsp.…”

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 two subspecies are small and variable. Therefore, this concept is sometimes questioned. To establish the genetic background of the two subspecies, populations of AMA and AMM together with herbarium samples and DNA Bank material of AMM were tested with 12 microsatellite markers. A. montana propagates by seeds or by clonal propagation of its rhizome. In AMA, clonality was frequent while in AMM only one case of clonality could be identified. Therefore, further results were clone-corrected. Genetically, AMA separated very well from AMM with a G ST between the subspecies of 0.81, genetically justifying the subspecies concept of A. montana. Genetic variability in AMA (H exp =0.28) was lower than in the AMM populations (H exp =0.70). A somewhat higher fixation index of AMA (F ST = 0.17, compared to an F ST =0.08 for AMM) may indicate that geneflow in AMA is a bit more restricted than in alpine AMM. However, the fixation index of AMA is not deviating from Hardy-Weinberg equilibrium. No inbreeding was observed for AMA (F IS = 0.10) and AMM (F IS =0.08).
