Monographs of invasive plants in Europe: Carpobrotus (2018, background): “During winter, soil moisture reaches 7% and decreases close to 0 during summer (Yelenik, Stock, and Richardson 2004).”
The invasive Sorghum halepense harbors endophytic N2-fixing bacteria and alters soil biogeochemistry (2009, background): “the most basic of ecosystem processes (Vitousek et al. 1987; Stock et al. 1995; Yelenik et al. 2004).”
Soil recovery after removal of the N2-fixing invasive Acacia longifolia: consequences for ecosystem restoration (2009, background): “…nutrient-poor ecosystems, nutrient enrichment has been shown to favour invasion by exotic plants, (Maron and Connors 1996; Pickart et al. 1998; Vinton and Burke 1995; Vinton and Goergen 2006; Yelenik et al. 2004), although higher nutrient availability not always favour exotics (Gross et al. 2005).”
High competitiveness of a resource demanding invasive acacia under low resource supply (2009, background): “These long-lasting changes of ecosystem nutrient cycling prevent quick restoration and may cause secondary invasions by nitrophilous exotic species (Maron and Jefferies 1999; Corbin and D’ Antonio 2004; Yelenik et al. 2004; Marchante et al. 2009).”
Impacts of alien plant invasions on species richness in Mediterranean-type ecosystems: a meta-analysis (2009, background): “, 2008), or changes of soil chemical properties (Witkowski, 1991; Musil, 1993; Yelenik et al., 2004; Lindsay and French, 2005).”
Biotic indirect effects: a neglected concept in invasion biology (2006, background): “…abiotic resource modification can have major impacts on an invaded system, as demonstrated by numerous recent studies (e.g. Fogarty & Facelli, 1999; Standish et al ., 2001; Lenz et al ., 2003; Wolf et al ., 2004; Yelenik et al ., 2004) (see Crooks, 2002 for a comprehensive review of this topic).”
Effects of exotic invasive trees on nitrogen cycling: a case study in Central Spain (2009, background): “The notable soil moisture decline in June (almost half that of the previous months, Table 3) may help explain the significant summer decline of adsorption resin-assessed N mineral availability, as resin membranes are dependent on water for transferring ions from the soil to the resin ( Yelenik et al”
Eucalyptus invasions in riparian forests: Effects on native vegetation community diversity, stand structure and composition (2013, background): “mearnsii is a nitrogen-fixing tree that causes nutrient enrichment, which may be unfavourable for native species (Witkowski, 1991; Yelenik et al., 2004).”
Invasive plants as drivers of regime shifts: identifying high‐priority invaders that alter feedback relationships (2014, background): “Prominent examples of nitrogen increase in nutrient-poor habitats are South African fynbos invaded by Australian Acacia species (Yelenik et al., 2004; Le Mâıtre et al., 2011), invasion of young volcanic soils in Hawaii by Fire tree (Morella faya) (Vitousek et al., 1987) and Black locust (Robinia…”
Invasive species: “back-seat drivers” of ecosystem change? (2012, positive): “…groups most vulnerable to invasion may not respond quickly due to dispersal limitation and alterations of nitrogen pools (Holmes and Cowling 1997; Yelenik et al. 2004), but overall, the reestablishment of native vegetation following Acacia removal supports the model of ecosystem recovery…”
Effect of invasive Acacia dealbata Link on soil microorganisms as determined by PCR-DGGE. (2010, positive): “Exotic plants can become invaders in the new regions, leading to profound changes in ecosystem processes, community structure and displacing native species (Yelenik et al., 2004; Callaway et al., 2005; Hierro et al., 2005).”
Functional Group Identity Does not Predict Invader Impacts: Differential Effects of Nitrogen-fixing Exotic Plants on Ecosystem Function (2007, methodology): “Therefore, higher levels of available N in soil may be facilitating secondary invasions by weedy nitrophilous grass species at Riverlands (P. Holmes, personal communication) such as Ehrharta calycina, which was found to be N-limited in a previous study (Yelenik et al. 2004).”
Plant invasion across space and time: factors affecting nonindigenous species success during four stages of invasion. (2007, background): “For example, invasions of nitrogen fixers into communities without native nitrogen fixers can increase the pool of soil nitrogen (Vitousek & Walker, 1989; Hughes & Denslow, 2005), facilitating the invasion of other NIPS previously limited by nitrogen availability (Yelenik et al., 2004).”
Impacts of invasive Australian acacias: implications for management and restoration (2011, background): “Restoration efforts have been carried out in several areas, with mixed results (Yelenik et al., 2004; Holmes et al., 2008; Marchante et al., 2009; Marchante et al., 2011a).”
Plant Invasions in Protected Areas (2013, background): “Other studies have provided documented evidence of modified nutrient regimes due to either increased nitrogen fixation or increased decomposing biomass (Musil and Midgley 1990; Yelenik et al. 2004) and impacts on seed banks of native fynbos species associated with Acacia saligna (Port Jackson willow”
