“…It was proved that invasive plants can alter the abundance or species composition of soil and sediment invertebrates, including fungivorous or bacterivorous nematodes, collembola, enchytraeids, and mites (Talley and Levin 2001;Yeates and Williams 2001;Quist et al 2014;Rusterholz et al 2014). These changes would possibly influence microorganisms as, depending on species and grazing intensity and selectivity, soil invertabrates can inhibit or stimulate mycelial growth and alter species dominance and composition within microbial communities (Hedlund and Augustsson 1995;Crowther et al 2011).…”

This study assessed the effects of Reynoutria japonica, Rudbeckia laciniata, and Solidago gigantea invading sites within and outside river valleys on activity, biomass, and composition of soil microbial communities. Microbial properties such as soil respiration, urease and arylsulfatase activities, microbial biomass (based on substrate-induced respiration, or SIR, and phospholipid fatty acids, or PLFA), and community composition (based on PLFA) were determined. R. japonica encroached on sites characterized by the lowest values of microbiological properties and R. laciniata on sites with the highest microbiological quality. The effect of invasion on soil microbial properties depended on the invasive plant species. R. japonica significantly decreased microbial biomass, determined by both SIR and total PLFA, urease activity, fungal PLFA, fungal:bacterial PLFA ratio, gram-negative bacterial PLFA, and soil respiration in comparison to soil under adjacent native plant communities. Microbial community composition also differed between soils under R. japonica and those under native plants. In contrast, R. laciniata and S. gigantea did not influence most microbial properties, though S. gigantea significantly increased fungal PLFA and R. laciniata and S. gigantea increased fungal:bacterial PLFA ratio. The effects of plant invasion on microbial properties were basically similar in soils located within and outside river valleys, probably because initially (i.e., before invasion) soils from the two locations were largely similar in terms of basic properties such as texture, moisture, pH, C:N ratio, and most microbial properties.

“…I. glandulifera reduces species richness of native plants, causes shifts in plant species composition in riparian habitats (Hejda & Pysek 2006), and competes successfully with native plants for pollinators which may reduce the fitness of native plants (Brown, Mitchell, & Graham 2002;Lopezaraiza-Mikel, Hayes, Whalley, & Memmott 2007). In mixed deciduous forests, I. glandulifera reduces the colonization rate of both arbuscular and ectomycorrhizal fungi on roots of native tree species , 2016 and alters the species composition of litter-dwelling invertebrates (Ruckli, Rusterholz, & Baur 2013;Rusterholz, Salamon, Ruckli, & Baur 2014).…”

“…Whilst the use of morphospecies in place of species level identification is well reported and defended (Oliver and Beattie 1996;Krell 2004), it would be valuable to incorporate measures of resource utilisation, foraging styles and microhabitat use (Ramey and Richardson 2017) into future studies to better understand the interactions between invertebrate taxa in riparian systems and to identify why some taxa are more sensitive to invasion. For example, taxonspecific reactions have been demonstrated in response to I. glandulifera invasion, which is able to modify the local microclimate, increasing local soil moisture and temperature, thereby promoting an increase in the abundance and diversity of gastropods (Ruckli et al 2013) and Acari (Rusterholz et al 2014). This study took place during the most active phase of the growing season when INNP are at their maximum extent and it would be valuable to determine if the observed effects are perpetuated after dieback.…”

All change at the water’s edge: invasion by non-native riparian plants negatively impacts terrestrial invertebrates

et al. 2019

Riparian zones are complex, dynamic habitats that play a critical role in river ecosystem functioning. Terrestrial invertebrates comprise much of the diversity found in riparian habitats and facilitate the transfer of energy between aquatic and terrestrial systems. However, the consequences for terrestrial invertebrates of invasion of riparian zones by invasive non-native plants (INNP) remain poorly understood. Responses of terrestrial macroinvertebrate morphospecies to invasion by two common INNP, Fallopia japonica (Japanese knotweed) and Impatiens glandulifera (Himalayan balsam) were assessed, relative to local environmental factors. Terrestrial invertebrates were collected from 20 sites on low order streams in June and August alongside data on physical attributes and land use. Greater cover of F. japonica and I. glandulifera cover reduced total invertebrate abundance and morphospecies diversity at the individual sample scale, whilst increasing spatial heterogeneity of invertebrates at the site scale. Impatiens glandulifera reduced morphospecies diversity at the site scale with increasing cover, but this was not observed for F. japonica. INNP affected terrestrial invertebrate morphospecies abundance and diversity, to a greater extent than prevailing environmental conditions. Our findings therefore offer support for managing riparian plant invasions to improve habitat heterogeneity, restore terrestrial invertebrate diversity and repair aquatic-terrestrial linkages.
