Hiking Trails Facilitate the Spread of a Native High‐Arctic Species

ABSTRACT High‐Arctic environments are facing an elevated pace of warming and increasing human activities, making them more susceptible to the introduction spread alien species. We investigated role disturbance in facilitating a native plant ( Papaver dahlianum ) high‐Arctic natural environment close Isfjord Radio station along adjacent hiking trails at Kapp Linné, Svalbard. reconstructed spatial pattern arrival P. Linné by combining historical records species occurrence (1928–2018) with contemporary survey abundance main trail (2023 survey) tested relative effects altitude proximity on density via generalised linear model (GLM). then compared simulated annual assuming either only local or plus from trails. Finally, we used fine‐scale UAV‐derived brightness index test for terrain preference applying randomisation test. Distance (56% explained variation) minimum distance (28%) significantly across research area (best GLM R 2 = 0.755). The modelled including effect (fitted ~30 m yr. −1 managed capture maximum extent occupied area, whereas simulations (~2 underestimated extent. A showed that has significant gravel soils low vegetation cover due trampling and/or processes. Along climate warming, activities can increase rate range shift providing hot spots (human settlements) spreading corridors (hiking trails). Our results show spatially explicit models be applied accurately predict potential species, leading efficient monitoring plan.

Anthropogenic factors, not altitude, shape native and nonnative plant species distributional patterns in a tropical mountain protected area

Invasive Plant Science and Management, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 8

Published: Jan. 17, 2025

Abstract Biological invasions pose a major threat to biodiversity conservation in protected areas, with roads, tracks, and trails being the main pathways for spread of non-native species. This study aimed assess distribution patterns native plant species relation elevational gradient, public use intensity, disturbance by roads tropical mountain forest southeastern Brazil. Specifically, we recorded along this gradient tested whether richness differed elevation. Additionally, investigated high-altitude community was subset lower-elevation communities linked anthropogenic disturbances intensity. Our findings revealed that varied gradient. Native exhibited hump-shaped pattern, peaking at mid-elevations. In contrast, did not show clear trend altitudinal Notably, higher observed roadside trailside plots. The altitudes were simply subsets those found lower elevations. Thus, while composition appeared be driven environmental factors presence more closely associated disturbances. summary, our results indicate plants, although widespread establish primarily most disturbed areas. Therefore, trails, human vehicular traffic are key determinants biological mountainous area.

The global distribution patterns of alien vertebrate richness in mountains

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: Feb. 26, 2025

The diverse biotas of the world's mountains face a challenging future due to increasing threats like climate change, land-use and biological invasions, last being particularly understudied in these regions. Here we compile occurrence records for 717 alien vertebrate species distributed 2984 worldwide. We analyze their distribution, biogeographic origin, presence protected areas, drivers' explaining richness mountains. find that vertebrates most frequently recorded are birds (318 species) mammals (161 reported 2595 1518 globally, respectively. Palearctic, Nearctic, Australasian realms common recipients; Indo-Malay, Afrotropic frequent donors. Almost 50% studied also occur areas. Proxies anthropogenic impacts (e.g., higher road density or lower biodiversity intactness) mountains' physical characteristics elevation range roughness) explain distribution Importantly, magnitude invasions tropical could be underestimated sampling bias towards Northern Hemisphere Australia. Our large-scale assessment reveals advance worldwide urges attention minimize on exceptional mountain biotas.

The importance of invertebrates in assessing the ecological impacts of hiking trails: A review of its role as indicators and recommendations for future research

Ecological Indicators, Journal Year: 2022, Volume and Issue: 137, P. 108741 - 108741

Published: March 7, 2022

Hiking is a natural exercise that has become one the most popular outdoor activities, promoting physical fitness and de-stress without large investments or special equipment. However, hiking downsides, particularly in areas which it takes place. From soil compaction erosion to disturbance ecological impacts, mounting evidence shows far from innocuous ecosystems. Despite spanning several decades, research on impacts of ecosystems pertinence using indicators still scarce. This work reviews published information conducted with invertebrates and, by doing so, offers insights guide not only management actions but also further investigation this scope. We address some current knowledge gaps provide recommendations focusing ground beetles (Coleoptera: Carabidae) for their sensitivity disturbance, representativeness due taxonomic functional diversity. Due limited number studies so far, classification species based habitat preference, within context trail non-consensual. Alternatively, such should derive its respective study avoid being generalized, done great caution. Additionally, sampling methods distinguish mortality behavioural changes were considered crucial determine possible effects. Ultimately, joint use both vegetation invertebrates, beetles, was relevant assess impacts.

Abstract The introduction and further spread of many alien species have been a result trade transport. Consequently, are often found close to traffic infrastructure urban areas. To contain manage the species, it is essential identify predict major routes spread, which cannot be obtained by applying common modelling approaches such as distribution models. Here, we present new model called CASPIAN simulate dispersal along establishment populations these routes. simulates simultaneous up eight different modes transport roads, railways waterways. We calibrated validated using two that within Germany case studies: terrestrial plant Senecio inaequidens freshwater clam Corbicula fluminea , performed shortest path analysis quantify relative importance individual for spread. application yielded detailed predictions >600,000 segments network throughout Germany. Once calibrated, captured general dynamics with higher accuracy environment due quality data available aquatic species. quantification revealed clear backbone varied depending on type starting points considered.
