Abstract. Climate warming is expected to induce treelines advance higher elevations. Empirical studies in diverse mountain ranges, however, give evidence of both advancing alpine and rather insignificant responses. The inconsistency findings suggests distinct differences the sensitivity global recent climate change.

Abstract Roadsides are major pathways of plant invasions in mountain regions. However, the increasing importance tourism may also turn hiking trails into conduits non-native spread to remote landscapes. Here, we evaluated such for invasion five protected areas southern central Chile. We therefore sampled native and species along 17 adjacent undisturbed vegetation. analyzed whether number cover local assemblages is related distance trail a additional variables that characterize abiotic biotic...

ABSTRACT Aim We aimed to examine the abiotic, biotic and anthropogenic drivers of non‐native plant species distribution along hiking trails in mountainous regions. Location Nine mountain regions across six continents, including North America (USA), South (Argentina Chile), Europe (Sweden, Norway, Czech Republic), Africa (South Africa), Asia (China) Oceania (Australia). Time Period Data were collected between 2016 2022 during summer season. Major Taxa Studied Vascular plants. Methods...

Abstract Aim The presence and use of trails may change plant species' realized climatic niches via modified abiotic biotic conditions including propagule transport, allowing competition‐pressed alpine species to expand their rear edges towards warmer locations lowland extend leading cooler locations. We investigated whether mountain indeed act as corridors for colonization shift niches, resulting in higher richness trailsides. Location Dovrefjell Abisko area the Scandes mountains Norway...

Abstract Rising human activity in the Arctic, combined with a warming climate, increases probability of introduction and establishment alien plant species. While settlements are known hotspots for persistent populations, little is about colonization particularly susceptible natural habitats. Systematic monitoring lacking available survey methods vary greatly. Here, we present most comprehensive vascular species high‐Arctic archipelago Svalbard to date, aimed at (i) providing status within...

Abstract Question Dark diversity refers to the set of species that are not observed in an area but could potentially occur based on suitable local environmental conditions. In this paper, we applied both niche‐based and co‐occurrence‐based methods estimate dark vascular plant subarctic mountains. We then aimed unravel drivers explaining (a) why some locations were missing relatively more than others, (b) certain often absent from others. Location The Scandinavian mountains around Abisko,...

Abstract Background Phlebotomus pedifer is the vector for Leishmania aethiopica causing cutaneous leishmaniasis (CL) in southwestern Ethiopia. Previous research on transmission dynamics of CL resulted recommendations control. In order to target these interventions towards affected areas, a comprehensive understanding spatial distribution P. at high resolution required. Therefore, this study determined environmental predictors that facilitate and created map indicating areas where conditions...

Abstract Aims Plant species' distribution ranges are expected to shift towards previously uncolonized locations in response climate warming. Mountain trails, which often access areas of special ecological value as well remote and climatically extreme locations, could influence such shifts through changes dispersal disturbance. Trails may facilitate the propagules new seed bank by changing propagule input persistence change establishment success creation gaps disruption biotic interactions....

The gold standard for studying natural selection and adaptation in the wild is to quantify lifetime fitness of individuals from populations that have been grown together a common garden, or reciprocally transplanted. By combining values with species traits genome sequences, one can infer coefficients at genetic level. Here we present rainfall-manipulation experiment 517 whole-genome sequenced accessions plant Arabidopsis thaliana spanning global distribution species. experiments were...

Abstract Hikers and livestock using mountain trails damage native vegetation act as seed vectors, thus favouring the spread of non-native plants. We evaluated effect abundance on success plants in arid central Andes Argentina. surveyed six trails, covering elevations between 2400 m 3570 a.s.l. recorded transects distributed along elevational gradient spanning distances up to 22 from trail. assessed how occurrence, richness cover varied with distance trail, intensity use by livestock, plant...
