Trophic trickles and cascades in a complex food web: impacts of a keystone predator on stream community structure and ecosystem processes (2008, methodology): “An alternative metric to estimate interaction strengths has been derived recently from allometric scaling relationships of predator prey body mass ratios (Emmerson and Raffaelli 2004), in the form of aij (Mj/Mi) , where Mi and Mj are the mean body masses of the prey and predator, respectively, and a”
Quantification and Resolution of a Complex, Size-Structured Food Web (2005, background): “, May, 1972) approaches to food web ecology, and there are suggestions that body size might constrain both the patterning and strength of trophic interactions (e.g., de Ruiter et al., 1995; Emmerson and RaVaelli, 2004).”
Diversity in a complex ecological network with two interaction types (2009, background): “Previous studies using predator� prey interactions showed the importance of weak links in long loops (Neutel et al. 2002), body size ratios ( Emmerson and Raffaelli 2004 ), and biological rates allometrically scaled to populations’ average body masses (Brose et al. 2006) for persistence and diversit”
Biodiversity and the functioning of seagrass ecosystems (2006, background): “Moreover, since large species tend to have correspondingly large per-capita effects on ecosystem processes (Emmerson & Raffaelli 2004, Solan et al. 2004), loss of large mobile invertebrates can reduce bioturbation, with important biogeochemical consequences (e.g. Aller & Yingst 1978, 1985, Emmerson…”
MEASUREMENT OF INTERACTION STRENGTH IN NATURE (2005, background): “Several empirical data sets are available for a preliminary analysis of allometric relationships (Emmerson & Raffaelli 2004, Sala & Graham 2002, Wootton 1997).”
Body size in ecological networks. (2005, background): “overfishing [42]; acidification [43]; species extinctions [44]; invasions of new species [45]), this could have potentially profound impacts on community stability and ecosystem functioning [11, 40 ].”
The microbial aspect of climate change (2016, background): “The rate of predation on grazers is expected to surge with temperature in proportion to the body mass of predators (Emmerson and Raffaelli 2004; Brose et al. 2006).”
Complexity and stability of ecological networks: a review of the theory (2018, methodology): “Emmerson and Raffaelli (2004) empirically estimated Lotka–Volterra interaction strengths and equilibrium population densities and used such a community matrix to evaluate (asymptotic) stability, showing that using empirical scaling laws the resulting food webs are always stable in contrast with…”
Ecological Networks in a Changing Climate (2010, background): “Three suchmodel systems include the Ythan Estuary in Scotland (e.g. Emmerson and Raffaelli, 2004), Broadstone Stream in southern England (Hildrew, 2009; Layer et al., 2010b) and Lough Hyne in Southern Ireland (O’Gorman et al., 2008, 2010; O’Gorman and Emmerson, 2010), all of which have been studied…”
Chapter 5 - Food Web Structure and Stability in 20 Streams Across a Wide pH Gradient (2010, methodology): “This has been recently proposed as a relatively straightforward method derived from allometric scaling relationships of predator–prey body mass ratios (Emmerson and Raffaelli, 2004), in the form of aij (Mj/Mi), where Mj and Mi are the mean body masses of the predator and prey species, respectively, ”
Does selective fishing conserve community biodiversity? Predictions from a length-based multispecies model (2011, result): “Increasing the preferred prey:predator mass ratio (m) and breadth of the sizepreference function (s) helped to stabilize the model dynamics, as would be expected from other studies (e.g., Benoı̂t and Rochet 2004; Emmerson and Raffaelli 2004).”
Complex Ecological Interactions in the Coffee Agroecosystem (2014, background): “On one hand, arthropods tend to be small but are major components of both herbivore and carnivore categories (Cohen et al. 1993, Emmerson & Raffaelli 2004).”
