Interesting times: winners, losers, and system shifts under climate change around Australia (2011, background): “Ecospace is an explicitly spatial form of the Ecopath with Ecosim (EwE) modelling approach (Walters et al., 2000; Christensen and Walters, 2004), which uses biomass pools to represent the ecological components of the system.”

Vulnerability of seamount fish to fishing: Fuzzy analysis of life-history attributes (2006, methodology): “We used a mass-balanced ecosystem model (Ecopath with Ecosim, see Christensen and Walters, 2004 for details) developed for a theoretical, isolated North Atlantic seamount (Morato and Pitcher, 2002).”

Structural Degradation in Mediterranean Sea Food Webs: Testing Ecological Hypotheses Using Stochastic and Mass-Balance Modelling (2008, methodology): “For this purpose, we used two different modelling approaches: a stochastic structural food-web model, the Niche model, which is an extension of the Cascade model and uses species richness (S) and connectance (C = Links/Species(2)) as input parameters to construct a web (Williams and Martinez 2000), ”
Interannual variability in the Northern California Current food web structure: Changes in energy flow pathways and the role of forage fish, euphausiids, and jellyfish (2012, methodology): “Each trophic network model was initially assembled using ECOPATH algorithms (Walters et al., 1997, Christensen and Walters, 2004) as revisions of the generalized seasonal models described in Ruzicka et al. (2007).”
Changes in the structure and function of the North Sea fish foodweb, 1973–2000, and the impacts of fishing and climate (2005, methodology): “, 2000; Christensen and Walters, 2004), though no implementation has yet been published for the North Sea. Greenstreet et al. (1997) proposed a different approach that was not based on considerations of mass balance. The basic idea was to calculate the food requirements of the fish assemblage from a”
Best practice in Ecopath with Ecosim food-web models for ecosystem-based management (2016, methodology): “…to annotate Ecopath input data with approprite references and to describe the origin of the data used to create he model in the model pedigree (Christensen and Walters, 2004; orissette, 2007), which describes the precision of the data and ets confidence intervals to be used with this data if…”

Lower trophic levels and detrital biomass control the Bay of Biscay continental shelf food web: Implications for ecosystem management (2011, background): “The paper of Christensen (1995) included several ecosystems for which the maturity state could be compared before and after a disturbance, notably fishing, and the findings were in all cases in agreement with disturbances leading to a reduction in maturity (Christensen and Walters, 2004).”
Assessing the trophic position and ecological role of squids in marine ecosystems by means of food-web models (2013, methodology): “At present, the Ecopath with Ecosim (EwE) approach and software (Christensen and Walters, 2004) is the most widely applied approach for building ecological models of marine ecosystems.”
