Summary Plant associated mutualists can mediate invasion success by affecting the ecological niche of nonnative plant species. Anthropogenic disturbance is also key in facilitating through changes biotic and abiotic conditions, but combined effect these two factors natural environments understudied. To better understand this interaction, we investigated how its interaction with mycorrhizas could impact range dynamics species mountains Norway. Therefore, studied root colonisation community composition arbuscular mycorrhizal (AM) fungi disturbed vs undisturbed plots along mountain roads. We found that roadside strongly increases fungal diversity richness while promoting AM an otherwise ecto‐mycorrhiza ericoid‐mycorrhiza dominated environment. Surprisingly, associating were present across whole elevation gradient, even above highest elevational limit plants, indicating are not currently limiting upward movement plants. conclude has a positive on richness, possibly supporting spread there no absolute limitation belowground mutualists, at high elevation.

Rapid climatic changes and increasing human influence at high elevations around the world will have profound impacts on mountain biodiversity. However, forecasts from statistical models (e.g. species distribution models) rarely consider that plant community could substantially lag behind changes, hindering our ability to make temporally realistic projections for coming century. Indeed, magnitudes of lags, relative importance different factors giving rise them, remain poorly understood. We review evidence three types lag: "dispersal lags" affecting species' spread along elevational gradients, "establishment following their arrival in recipient communities, "extinction resident species. Variation lags is explained by variation among physiological demographic responses, effects altered biotic interactions, aspects physical environment. Of these, interactions contribute establishment extinction yet range dynamics are develop a mechanistic model illustrate how turnover future communities might simple expectations based shifts with unlimited dispersal.

Abstract Elevational gradients are often used to quantify how traits of plant species respond abiotic and biotic environmental variations.

Abstract High-elevation ecosystems are among the few worldwide that not yet heavily invaded by non-native plants. This is expected to change as species expand their range limits upwards fill climatic niches and respond ongoing anthropogenic disturbances. Yet, whether how quickly these changes happening has only been assessed in a isolated cases. Starting 2007, we conducted repeated surveys of plant distributions along mountain roads 11 regions from 5 continents. We show over 5- 10-year period, number increased on average approximately 16% per decade across regions.

Invasive species significantly impact biodiversity and ecosystem services, yet understanding these effects at large spatial scales remains a challenge. Our study addresses this gap by assessing the current potential future risks posed 94 invasive to seven key services in Europe. We demonstrate widespread impacts, particularly on outdoor recreation, habitat maintenance, crop provisioning, soil nitrogen retention. Exposure was higher areas with lower provision of for regulating cultural services. also high where contributions retention were their highest. Notably, regions vital currently have low invasion suitability, but face an average 77% increase area. Here we show that, while high-value service highest risk represent small fraction Europe (0-13%), they are disproportionally important conservation. underscores importance monitoring protecting hotspots align management strategies international targets, considering both vulnerability sustainability.

Abstract Aim Although species distribution models (SDMs) traditionally link occurrences to free‐air temperature data at coarse spatio‐temporal resolution, the of organisms might instead be driven by temperatures more proximal their habitats. Several solutions are currently available, such as downscaled or interpolated coarse‐grained temperatures, satellite‐measured land surface (LST) in‐situ‐measured soil temperatures.
