Stable isotope profiles of large marine predators: Viable indicators of trophic position, diet, and movement in sharks? (2011, background): “Specifically, for analysis of community trophic structure (Jennings et al. 2001; Layman et al. 2005), (i) within-species size-based variation and (ii) associated size-based habitat shifts are not clearly defined and (or) generally accounted for.”
BODY SIZE AND TROPHIC POSITION IN A DIVERSE TROPICAL FOOD WEB (2005, background): “Body mass and length produce similar predator–prey sizebased patterns (Jennings et al. 2001, Cohen et al. 2003), and we present size data based on the latter.”
Interaction strengths in food webs: issues and opportunities (2004, background): “…can be abstracted into key traits that determine probable feeding relationships, preferences and magnitudes (Cohen 1989; Warren 1996; Williams & Martinez 2000; Jennings et al. 2001; Hooper et al. 2002; Petchey & Gaston 2002; Woodward & Hildrew 2002; Brown & Gillooly 2003; Cohen et al. 2003).”
Abundance-body mass relationships in size-structured food webs (2003, background): “While the mean body mass of species is only weakly correlated with their trophic level, trophic level increases continuously with body mass in the whole food web (Fry & Quinones 1994; France et al. 1998; Jennings et al. 2001, 2002a ).”
Coupled energy pathways and the resilience of size-structured food webs (2011, background): “…of this view is that individual organisms often change in body size over several orders of magnitude within the course of their lives (Kerr and Dickie 2001; Belgrano et al. 2005), and trophic links are more strongly dictated by an individual's body size than species identity (Jennings et al. 2001).”
Body size and trophic position in a temperate estuarine food web (2008, methodology): “In addition to trophic level estimated with the formula used above, nitrogen stable isotope values (d15N) as suggested by Jennings et al. (2001) were also used as an index of trophic level to explore the relationships with body size (length and weight).”
Modeling What We Sample and Sampling What We Model: Challenges for Zooplankton Model Assessment (2017, background): “Developed over the past 50 years, this approach is based on empirical observations that individual and community processes such as growth, respiration, and predator-prey relationships and trophic position all scale with body size (Peters, 1983; Jennings et al., 2001; Brown et al., 2004; Andersen et ”
Indications of competition between non-indigenous round goby and native flounder in the Baltic Sea (2007, background): “comm.). In support of the nitrogen isotope signatures, feeding on bivalves by both species investigated here increased with size of fish, indicating an ontogenetic diet shift in both species, as suggested by Sko´ra and Rzeznik (2001) and Jennings et al. (2001) .”
On the relationship between trophic position, body mass and temperature: reformulating the energy limitation hypothesis (2007, background): “…have shown a negative relationship (Burness et al. 2001) as well as no association between trophic position and size (Vander Zanden et al. 2000, Jennings et al. 2001, Cocheret de la Morinière et al. 2003, Swanson et al. 2003, Deudero et al. 2004, Layman et al. 2005), suggesting that this…”
Body size in ecological networks. (2005, background): “For example, Jennings et al. [ 21 ] showed that log2 body mass explained 93% of the variation in trophic level (as defined by d15N‰”
Feeding habits and trophic levels of bluefin tuna Thunnus thynnus of different size classes in the Mediterranean Sea (2007, background): “The stable isotope approach (Das et al., 2000; Jennings et al., 2001; Olson et al., 2004; Estrada et al., 2005) can elucidate some interactions within ecological communities by enabling the”
