“…In Kashmir Himalaya, as many as 54 alien species of Asteraceae have been reported, and some of these have become naturalized and displace the native vegetation (Khuroo et al 2007). Some of these alien species have become invasive and have negative effects on the growth and propagation of native biodiversity (Ahmad et al 2019a;2019b). In this context, we record for the first time S. subulatum as an alien plant in the Kashmir Himalaya, India.…”

Symphyotrichum subulatum (Michx.) G.L.Nesom (Asteraceae) is reported as a new alien plant record for Kashmir Himalaya. The taxonomic identification of species is confirmed on the basis of shape of involucre, floral and seed characters. Detailed description, distribution map, and comments on distribution and ecology are also provided along with photographic illustration to facilitate easy identification of this species.

“…Aliens may change soil structure through changes of soil bulk density and the patterns of soil particle aggregation, ultimately changing the hydrological regime (Weidenhamer and Callaway 2010). Effects on soil chemistry and nutrient resources have also been documented (Ahmad et al 2020;). Another affected soil component is the soil biota: the properties of soil microbial communities in uenced by invasive plants include biomass (Liao and Boutton 2008) or composition and diversity of soil bacterial, protist and fungal communities (Ravit et In effect, the plant-soil microbiota feedback can be both positive and negative: soil microorganisms can both promote and control plant invasion (Callaway et al 2004).…”

Background and Aims Invasive species are a threat to the conservation of biological systems. In Central Europe, riparian ecosystems are especially susceptible to plant invasions, as waterflow mediates the spread of plant propagules, while invasive species may then affect soil including soil microbial communities. As waterflow also enhances connectivity among different segments of a river, spatial continuity of abiotic as well as biotic components of riparian ecosystems is expected. Methods We studied activity and functional diversity of microbial communities in three headwater streams in Central Europe. Plant diversity, soil properties and soil microbiota were assessed on 20 sample plots per river regularly distributed along the streams. Soil microbial activity and community-level physiological profiling were used to study the soil microbial community. Results Although the α-diversity of plants and soil microbiota was comparable, plant communities were substantially more differentiated than microbial communities. Richness in alien and invasive plants significantly differed among rivers, which was reflected in different spatial patterns and trends of microbial activity and diversity. A high level of spatial continuity and clearest longitudinal trends were observed in the Kysuca river with straightened riverbed and a high occurrence of artificial surfaces in the adjacent areas. The number of both alien and invasive plants significantly affects the composition of microbial functional groups of riverbed soils. Conclusion Continuity of processes in riparian ecosystems was confirmed also for headwater streams. However, the extent to which it applies to a particular stream strongly depends on particular environmental setting and stream characteristics.

“…Alien species invading ecosystems are a major driver of global environmental change and the second greatest threat to biodiversity, following habitat loss [ 1 ]. These invasive species have significant effects on ecosystem structure and function, including a reduction in diversity of native plant species, alterations in soil nutrient pools and fluxes, and changes in ecosystem productivity [ 2 , 3 , 4 ]. The ecological impacts of invasive species are extensive and have been focused based on their effects on aboveground terrestrial plant communities’ diversity and dynamics as well as below-ground ecosystem structure and function, specifically the dynamics of the soil system [ 5 , 6 , 7 , 8 ].…”

Plant invasions can have long-lasting impacts on soil nitrification, which plays a critical role in nutrient cycling and plant growth. This review examines the legacy effects of plant invasion on soil nitrification, focusing on the underlying mechanisms, context dependence, and implications for management. We synthesize literature on the positive, negative and neutral legacy effects of plant invasion on soil nitrification, highlighting the complexity of these effects and the need for further research to fully understand them. Positive legacy effects include increased soil microbial biomass or activity, potentially enhancing nutrient availability for plants. However, negative legacy effects, like reduced nitrifier abundance, can result in decreased soil nitrification rates and nutrient availability. In some cases, changes to nitrification during active invasion appear transitory after the removal of invasive plants, indicating neutral short-term legacies. We discuss the context dependence of legacy effects considering factors, including location, specific invasive plant species, and other environmental conditions. Furthermore, we discuss the implications of these legacy effects for management and restoration strategies, such as the removal or control of invasive plants, and potential approaches for restoring ecosystems with legacy effects on soil nitrification. Finally, we highlight future research directions, including further investigation into the mechanisms and context dependence of legacy effects, and the role of plant–microbe interactions. Overall, this review provides insights into the legacy effects of plant invasion on soil nitrification and their implications for ecosystems.
