Spatio-temporal heterogeneity in abiotic factors modulate multiple ontogenetic shifts between competition and facilitation (2010, methodology): “The average ring width of each of these four groups was used to estimate the effect of S. tenacissima on the growth of L. subulatum throughout the ontogeny of the later by using the relative interaction index (RII; Armas et al., 2004).”
Facilitation in plant communities: the past, the present, and the future (2007, background): “2007); the use of indices in plant interaction studies (as hotly debated with respect to competition indices; Markham & Chanway 1996; Freckleton & Watkinson 1997a,b, 1999; Markham 1997; Weigelt & Jolliffe 2003; Armas et al. 2004; Wilson 2007); and the possible contrasting consequences of diffuse and”
A field test of the stress-gradient hypothesis along an aridity gradient (2011, methodology): “RIIb = relative interaction intensity (effect of the interaction on biomass); RIIb = relative interaction frequency (effect of the interaction on species richness).”
Early root growth plasticity in seedlings of three Mediterranean woody species (2007, neutral): “From seedling root length in reduced and control water levels at harvest, we calculated for each species the relative interaction index (RII, Armas et al. 2004) as an index of root plasticity to reduced watering, expressed as: RII ¼ ðRr RcÞðRr þ RcÞ ð2Þ where Rr and Rc were root length in reduced…”
The importance of importance (2005, background): “Therefore suitable indices for expressing Cint are RCI, the relative competition intensity index (Grace 1993), or the more recent RNE, relative neighbor effect (Markham and Chanway 1996, Armas et al. 2004).”
Biological soil crusts greatly contribute to small-scale soil heterogeneity along a grazing gradient (2013, methodology): “…of grazing impact, or whether grazing modifies SSC effect/response pattern, we calculated the Relative Interaction Intensity (RII) index (Armas et al., 2004) for D. diacapsis and conducted 14 separate analyses of variance (ANOVAs) for each soil property with site as fixed factor (four…”
Local and regional assessments of the impacts of plant invaders on vegetation structure and soil properties of Mediterranean islands (2006, methodology): “The RII has better mathematical and statistical properties compared with classical indices such as the relative neighbour effect or the log response ratio (Goldberg et al., 1999).”
