• Functional Group Identity Does not Predict Invader Impacts: Differential Effects of Nitrogen-fixing Exotic Plants on Ecosystem Function (2007, background): “Knops et al. (2002) postulate that large inputs of low quality carbon can cause nitrogen to be tied up in the microbial biomass pool, leading to high soil total N.”
• Arbuscular mycorrhizae and terrestrial ecosystem processes (2004, background): “In the plant ecology literature, there is a rich database and theoretical framework for the role of plant species traits in influencing ecosystem properties (e.g. Hobbie 1992; Chapin et al. 1997; Cornelissen et al. 2001; Knops et al. 2002; Wardle 2002; Eviner & Chapin 2003).”
• Biological Nitrification Inhibition—A Novel Strategy to Regulate Nitrification in Agricultural Systems (2012, unknown): “The hypothesis that plants can suppress or stimulate nitrification has been debated for a long time, but with limited evidence from in situ studies (Fillery, 2007; Ishikawa et al., 2003; Knops et al., 2002; Lata et al., 1999; 2004; Lovett et al., 2004; Smits et al., 2010a,b; Stienstra et al., 1994; ”
• Differential nitrogen and phosphorus retention by five wetland plant species (2003, background): “Plant species can have distinctly different effects on ecosystem nutrient cycling due to differential uptake and losses (Hobbie 1992, Knops et al. 2002).”
• Phenology of fine roots and leaves in forest and grassland (2008, background): “Increased grassland fine root production due to increasing soil temperature may also restrict tree establishment by limiting soil nitrogen availability both via uptake and microbial immobilization, because fine roots are an important source of carbon for soil microbes (Knops et al. 2002).”
• Rapid effects of plant species diversity and identity on soil microbial communities in experimental grassland ecosystems (2006, background): “Despite the importance of these organisms for ecosystem functioning, relatively little is known about the relationship between plant species composition and the diversity of soil microorganisms (Wardle et al., 1999; Broughton and Gross, 2000; Stephan et al., 2000; Niklaus et al., 2001; Knops et al.,”
• Global legume diversity assessment: Concepts, key indicators, and strategies (2013, background): “Kreft & Jetz (2007) modeled and mapped global patterns of vascular plant species richness but did not carry out any assessment of trends (species decline/loss).”
• Niche construction by the invasive Asian knotweeds (species complex Fallopia): impact on activity, abundance and community structure of denitrifiers and nitrifiers (2011, unknown): “However, according to Knops et al. (2002), the litter quality of a plant does not matter much and a plant really modifies N cycling if it changes N inputs (N symbiotic and asymbiotic fixation, atmospheric deposition interception) or N losses (nitrate leaching, denitrification, fire, herbivores).”
• Inorganic soil nitrogen under grassland plant communities of different species composition and diversity. (2005, background): “Another explanation to the lack of correlation between biomass and soil nitrate could be the strong microbial control of soil N availability in grasslands (Knops et al. 2002).”
• Does the Type of Disturbance Matter When Restoring Disturbance‐Dependent Grasslands? (2007, background): “The effects of fire-available nitrogen could have been positive due to feedbacks between ash deposition, litter quality (lower C:N ratios), and litter quantity (Covington & Sackett 1992; Blair 1997; Knops et al. 2002).”
• Altered ecosystem carbon and nitrogen cycles by plant invasion: a meta-analysis. (2008, background): “Third, increase in soil microbial biomass C and N (Table 1) could stimulate net N accumulation in invaded ecosystems relative to native ones (Chapin et al., 2002; Knops et al., 2002).”
