Inferring species interactions in ecological communities: a comparison of methods at different levels of complexity (2015, methodology): “S), where we are assuming constant interaction269 coefficients (Berlow et al. 2004)270 J = [∂(dni/dt)∂nj]n?”
The Network Structure of Food Webs (2005, background): “More recent research suggests that “non-random patterning of strong and weak links can be critical for the stability or persistence of theoretical and empirically observed complex communities” (Berlow et al. 2004; de Ruiter et al. 1995; Kokkoris et al. 1999; Neutel et al. 2002).”
Temperature, predator–prey interaction strength and population stability (2009, methodology): “Often, interaction strength is measured as the log ratio between prey density in treatments with predators vs. prey density in treatments without predators (Berlow et al., 1999, 2004).”
Freshwater food webs: towards a more fundamental understanding of biodiversity and community dynamics (2012, background): “There are many ways to quantify linkage or interaction strength, one of the key aspects of food-web research (Berlow et al., 2004, Berlow et al., 2009; Wootton & Emmerson, 2005), 2012 Blackwell Publishing Ltd, Freshwater Biology, doi:10.1111/j.1365-2427.2012.02808.x and the particular form used…”
Why network analysis is often disconnected from community ecology: A critique and an ecologist's guide (2010, background): “Apart from niche-based questions, the ecological impact (or interaction strength) among species within a community and ecosystem is a typical focus of ecological studies (Wootton & Emmerson, 2005) including food web analyses (Berlow et al., 2004).”
Context‐dependent fruit–frugivore interactions: partner identities and spatio‐temporal variations (2013, background): “This would help to quantify the strength of the interactions in large assemblages, which has been traditionally considered a major limitation on species interaction networks (Berlow et al. 2004, Vázquez et al. 2005).”
Production sources and food web structure of a temperate tidal estuary: integration of dietary and stable isotope data (2007, background): “Empirical estimation of species abundances and the strengths of species interactions is a major challenge for food web research (Berlow et al. 2004, Winemiller & Layman 2005).”
Complexity and stability of ecological networks: a review of the theory (2018, background): “, there are many weak interactions and few strong ones (Paine 1992; Berlow 1999; Berlow et al. 2004; Wootton and Emmerson 2005).”
Indirect Interaction Webs: Herbivore-Induced Effects Through Trait Change in Plants (2005, background): “INTRODUCTION A central issue in ecology is understanding how trophic interactions make up food webs in various ecosystems (Berlow et al. 2004, Hunter & Price 1992, Paine 1980, Polis & Winemiller 1996).”
Describe, understand and predict: why do we need networks in ecology? (2016, background): “Although the identification of trophic interactions may rely on observations alone (although several observations of a feeding event are needed to make sure that the prey is actually part of the diet of the predator), other interaction types typically require experiments (Berlow et al. 2004; Godoy e”
Quantification and Resolution of a Complex, Size-Structured Food Web (2005, background): “Unfortunately, interaction strength (sensu stricto, May, 1973) is notoriously diYcult to measure in real systems, although approximations may be made from empirical and experimental evidence to provide insight into the relative importance of diVerent links (Berlow et al., 2004).”
