Grass invasion of a hardwood forest is associated with declines in belowground carbon pools (2010, background): “M. vimineum invasion is linked to increased nonnative earthworm biomass in northeastern US forests (Kourtev et al., 1998, 1999; Nuzzo et al., 2009) so we accounted for this potential confounding issue.”
Environmental Correlates of the Distribution and Abundance of Microstegium vimineum, in East Tennessee (2004, background): “Kourtev et al.(1999) reported that soils that supported M. vimineum were higher in pH than soils under native vegetation; however, it cannot be determined from either their data or ours whether soil pH was altered by M. vimineum or was related to a site’s likelihood of being invaded by M. vimineum.”
Light limitation creates patchy distribution of an invasive grass in eastern deciduous forests (2005, unknown): “Its rapid expansion of range since its introduction, and its tendency to become the dominant understory plant species in many invaded habitats, has raised concerns about its potential to displace native plant species and change ecosystem properties (Kourtev et al. 1999; Ehrenfeld et al. 2001).”
Alien plant invasion and their impact on indigenous species diversity at global scale: A review (2010, background): “Further, available nitrate and net potential nitrification were significantly higher in soils under the two exotic species (Kourtev et al., 1999).”
NET IMPACT OF A PLANT INVASION ON NITROGEN-CYCLING PROCESSES WITHIN A BRACKISH TIDAL MARSH (2003, background): “For example, Kourtev et al. (1999, 2003) found that nitrification rates and extractable nitrate concentrations were increased under both an exotic shrub and an exotic grass that invade eastern deciduous forests.”
Does the invasive species Reynoutria japonica have an impact on soil and flora in urban wastelands? (2009, background): “Some authors emphasise that these effects matter for the restoration of local flora, as higher nitrate content, for example, can inhibit the growth of several native species, alter dominance relationships in the plant community, and hence curb the restoration process (Kourtev et al. 1999; Yu et al. ”
European buckthorn and Asian soybean aphid as components of an extensive invasional meltdown in North America (2010, background): “…suggested that introduced earthworms facilitate the establishment of introduced plants and other invaders, and in turn that introduced plants facilitate earthworm invasions, leading to the potential for positive feedback among invaders (Aplet et al. 1991; Kourtev et al. 1999; Frelich et al. 2006).”
Experimental plant invasion reduces arthropod abundance and richness across multiple trophic levels (2010, background): “…compared to the soil below native plant species, the soil beneath M. vimineum has a higher pH and a higher nitrification rate, differs in the structure and function of the microbial community, and supports significantly higher earthworm densities (Kourtev et al. 1999, 2002, Ehrenfeld et al. 2001).”
Mechanisms underlying the impacts of exotic plant invasions (2003, background): “In hardwood forests of New Jersey, Kourtev et al. (1999) found higher earthworm densities under the introduced Berberis thunbergii and Microstegium vimineum than under the native Vaccinium spp.”
How common are invasion-induced ecosystem impacts? (2011, background): “Kourtev et al. (1999) studied the interaction between European earthworms and two invasive introduced plants, Japanese barberry (Berberis thunbergii) and Japan grass (Microstegium vimineum), in New Jersey.”
Fifty years of change in northern upland forest understories: Identity and traits of “winner” and “loser” plant species (2006, background): “Large exotic earthworms (lumbricids), in particular, appear to reduce the leaf litter layer, disrupt the rooting zone and modify the soil environment so as to reduce densities of tree seedlings and rarer herbs while favoring some invasive plants (Kourtev et al., 1999; Gundale, 2002).”
