“…Due to its location in the transition between the Alpine, Mediterranean, and Atlantic biogeographic regions, together with a broad altitudinal gradient (highest summit at 3404 m a.s.l. ), the Pyrenees show a wide variety of climatic conditions (Ninot, Carrillo, & Ferré, 2017). This, combined with intensive land use (García‐Ruiz et al, 1996), and geological heterogeneity (García‐Ruiz et al, 2015), results in a wide diversity of natural and semi‐natural habitats.…”

Biodiversity is being severely affected by global change worldwide, but consequences differ across individual species and environments. Since rarity is a condition associated with vulnerability and extinction risk, it is a concerning factor itself that can also amplify the detrimental impact of global change drivers. Here, we assess differences in vulnerability derived from species rarity across environments in a South European mountain range, the Pyrenees, a complex landscape sheltering more than 3400 vascular plants. We first analyzed patterns of alpha taxonomic (richness) and phylogenetic diversity (standardized phylogenetic diversity, sesPD) from more than 18,000 plant surveys across 14 different habitats to find out which ones shelter the highest diversity. Then, we classified plant species according to four criteria of rarity (Pyrenean endemic, regional geographic range, ecological specialization and local abundance) and estimated their frequency among habitats and their contribution to PD. Generalized linear models were used to compare richness and sesPD among habitats, and the relationship between each diversity metric and rare species proportion was assessed. Grasslands harbor the greatest number of species but are poor in sesPD, while inland surface waters contain fewer species but are the most phylogenetically diverse. Deciduous, evergreen and Mediterranean forests show both high species richness and sesPD. Rare species account for half of the regional species pool, and are more abundant in habitats with fewer species and higher sesPD. Diversity metrics showed opposite tendencies between them and with rare species proportion, emphasizing that they are not interchangeable. Our results highlight the vulnerability of rocky and water‐related habitats due to the rarity of the species they shelter, but only the latter match other assessments of habitat vulnerability to global change drivers. The analysis of rarity patterns can guide conservation efforts by identifying priority targets when information about direct threats to habitats is scarce or incomplete.

“…The more intense reduction in potential niches suitable for K. procumbens in the Central as opposed to the East Pyrenees could be explained by the more continental climate of the Central Pyrenees, influenced by the close distance to the very dry and warm central part of the Ebro Basin from the south. This could reduce the influence of the Atlantic climate [58,66]. In fact, the westernmost localities of the species were detected on the northern macroslopes of the Pyrenees, with the more prominent impact of the Atlantic climate (Figure 1).…”

“…1926. In the Pyrenees, the plant community Cetrario nivalis-Loiseleurietum is developed on the north-exposed, acid sites where the winds blow out snow, thus reducing snow cover [49,50,57,58,60]. A similar plant community is formed in the South Carpathians [61,62], and a fragmentary community is formed in the East Carpathians [38,56].…”

High-mountain and arctic plants are considered especially sensitive to climate change because of their close adaptation to the cold environment. Kalmia procumbens, a typical arctic–alpine species, reaches southernmost European localities in the Pyrenees and Carpathians. The aim of this study was the assessment and comparison of the current potential niche areas of K. procumbens in the Pyrenees and Carpathians and their possible reduction due to climate change, depending on the scenario. The realized niches of K. procumbens in the Pyrenees are compact, while those in the Carpathians are dispersed. In both mountain chains, the species occurs in the alpine and subalpine vegetation belts, going down to elevations of about 1500–1600 m, while the most elevated localities in the Pyrenees are at ca. 3000 m, about 500 m higher than those in the Carpathians. The localities of K. procumbens in the Carpathians have a more continental climate than those in the Pyrenees, with lower precipitation and temperatures but higher seasonality of temperature and precipitation. The species covered a larger area of geographic range during the Last Glacial Maximum, but its geographic range was reduced during the mid-Holocene. Due to climate warming, a reduction in the potential area of occurrence could be expected in 2100; this reduction is expected to be strong in the Carpathians and moderate in the Pyrenees.
