Grazing triggers soil carbon loss by altering plant roots and their control on soil microbial community (2009, background): “As grazing affects root biomass and activity (Holland & Detling 1990; Guitan & Bardgett 2000; Hamilton & Frank 2001) changes in soil communities and litter decomposition may be provoked by a change in living roots rather than litter quality.”
The influence of below-ground herbivory and defoliation of a legume on nitrogen transfer to neighbouring plants. (2007, background): “... exudation of isotopically labelled C from roots into the soil (Holland, Chang & Crossley 1996; Hamilton & Frank 2001; Paterson et al . 2003, 2005; Murray et al . 2004; but cf. Todorovic et al . 1999; Mikola & Kytoviita 2002; Dilkes, Jones & Farrar 2004), which can stimulate microbial activity in”
LARGE HERBIVORES SUPPRESS DECOMPOSER ABUNDANCE IN A SEMIARID GRAZING ECOSYSTEM (2004, background): “First, in the short term, grazers can enhance the amount of labile C entering soils by stimulating root exudation in plants (Holland et al. 1996, Guitian and Bardgett 2000, Hamilton and Frank 2001).”
Contribution of exudates, arbuscular mycorrhizal fungi and litter depositions to the rhizosphere priming effect induced by grassland species (2015, background): “It has been suggested that exudates from roots and root-associated mycorrhizae provide energy-rich substrates to rhizosphere microbes thereby enabling them to secrete extracellular enzymes responsible for the accelerated SOM decomposition (Clarholm, 1985; Hamilton and Frank, 2001).”
Plant clipping decelerates the mineralization of recalcitrant soil organic matter under multiple grassland species (2012, background): “other hand, it has been shown that mowing/defoliation can result in increased soluble C, microbial biomass and nitrogen availability in soil (Hamilton and Frank, 2001; Henry et al., 2008).”
Root Exudates Regulate Soil Fungal Community Composition and Diversity (2007, background): “Interactions between plants and soil microbes are highly dynamic in nature and based on coevolutionary pressures (6, 7, 10, 15, 16, 20, 21, 29).”
Herbivore-mediated linkages between aboveground and belowground communities (2003, background): “…Holland et al. 1996) and root (Yeates et al. 1998) herbivory have been shown to increase root exudation in grassland plants, which in turn stimulates microbial biomass and activity in the rhizosphere (Denton et al. 1999, Hamilton and Frank 2001), and microbe-feeding fauna (Mikola et al. 2001a).”
An integrated perspective to explain nitrogen mineralization in grazed ecosystems (2013, background): “…of nutrients to roots and they may stimlate root exudation in plants (Holland and Detling, 1990), which ay favour soil microbial activity (Hamilton and Frank, 2001). ccelerated N cycling enhances plant N uptake and leaf N conentrations (e.g. Holland and Detling, 1990; Hamilton and Frank,…”
Tree physiological responses to above-ground herbivory directly modify below-ground processes of soil carbon and nitrogen cycling (2004, methodology): “However, herbivore-induced increases in N mineralization have also been shown to result from short-term plant physiological responses to clipping, in the form of enhanced root exudation that stimulates microbial activity in the root zone ( Hamilton & Frank 2001 ).”
Importance of rhizodeposition in the coupling of plant and microbial productivity (2003, background): “Using 13C-labelling of grazing-tolerant Poa pratensis, Hamilton & Frank (2001) demonstrated that these exudates were quickly used by microorganisms in the rhizosphere and were associated with increased available N and increased concentrations of N in shoots, relative to uncut plants.”
Defoliation and patchy nutrient return drive grazing effects on plant and soil properties in a dairy cow pasture (2009, methodology): “…of plant shoot tissue, has effects on plant growth and carbon allocation (Briske et al. 1996, Ferraro and Oesterheld 2002), which can influence root carbon exudation (Paterson and Sim 1999) and the rhizosphere organisms that rely on the carbon released from plant roots (Hamilton and Frank 2001).”
Soil‐mediated effects of invasive ungulates on native tree seedlings (2014, background): “Ungulates can also affect soil properties via shifts in plant nutrient and carbon (C) allocation strategies (Hamilton & Frank 2001; Ayres et al. 2004), in turn increasing microbial activity (Hamilton et al. 2008).”
