DEFINING A PLANT'S BELOWGROUND ZONE OF INFLUENCE (2003, background): “Much recent work on the design of whole root systems (Einsmann et al. 1999, Johnson and Biondini 2001, Wijesinghe et al. 2001) has been motivated by Campbell et al.’s (1991) study showing a tradeoff in the scale and precision of root foraging.”
Trade-off between root nitrogen acquisition and shoot nitrogen utilization across 13 co-occurring pasture grass species (2009, background): “Additionally, different root foraging strategies are likely to be developed to reach N patches and a trade-off between root foraging scale (size of root system) and precision (efficiency of root captor) can occur (Wijesinghe et al. 2001; but see Kembel & Cahill 2005).”
Ecological constraints on the evolution of plasticity in plants (2002, methodology): “Specifically, we need to take models like those of Zhivotovsky et al. (1996), van Tienderen (1997), and Tufto (2000) and incorporate explicit spatial and spatio-temporal structure, so that we can analyze how rates of migration, phenotypic change, temporal variation in conditions 221”
The plastic plant: root responses to heterogeneous supplies of nutrients (2004, background): “However, in addition to differences between species, considerable variation within species can occur depending on the scale of heterogeneity (Wijesinghe et al., 2001).”
Contrasting root behaviour in two grass species: a test of functionality in dynamic heterogeneous conditions (2011, background): “Differences in root foraging behaviour have long been interpreted as a trade-off between precision and scale (Campbell et al. 1991; Farley and Fitter 1999; Wijesinghe et al. 2001; Rajaniemi and Reynolds 2004), with dominant species employing low-precision foraging at high scale and subordinate speci”
Acquisition of phosphorus and nitrogen in the rhizosphere and plant growth promotion by microorganisms (2009, background): “However, foraging is not a fixed property but varies within species in response to different environmental conditions (Wijesinghe et al. 2001), indicating that the environmental context in which the root response is expressed is as important as the response itself.”
The effects of spatially heterogeneous nutrient supply on yield, intensity of competition and root placement patterns in Briza media and Festuca ovina (2003, background): “Such 'efficiency gains' may explain why some species produce more biomass in heterogeneous conditions than in homogeneous conditions providing the same supply of nutrients (Birch & Hutchings 1994; Einsmann et al. 1999; Wijesinghe et al. 2001).”
The effects of spatial pattern of nutrient supply on yield, structure and mortality in plant populations (2003, background): “Possible reasons are that the scale of heterogeneity used may have been inappropriate for the species investigated to respond to (Wijesinghe et al. 2001; Hutchings et al. 2003), or that growth had become resource-limited.”
The Behavioral Ecology of Nutrient Foraging by Plants (2011, background): “Similarly, Wijesinghe et al. (2001) found that none of six herbaceous species altered foraging precision as a function of plant mycorrhizal status.”
