Seasonal changes in the importance of the source of organic matter to the diet of zooplankton in Loch Ness, as indicated by stable isotope analysis (2001, background): “Such high d15N diet-tissue fractionation has been reported in daphnids maintained on an algal diet with high C : N ratios (Adams and Sterner 2000).”
The soil food web: structure and perspectives (2002, background): “Furthermore, fractionation of (15)N may vary with food quality as indicated by studies on locusts [81] and cladocerans [2]; in addition, the (15)N content in animal tissue is known to change in starving animals [68,70].”
Trophic relationships along a bathymetric gradient at the deep-sea observatory HAUSGARTEN (2009, background): “4% is a valid estimate of trophic fractionation only when averaged over multiple trophic pathways and that any single trophic transfer is likely to range between 2% and 5% (Adams and Sterner, 2000).”
Variability of diet-tissue isotopic fractionation in estuarine macrobenthos (2005, background): “Adams & Sterner (2000) also found a similar phenomenon in the relationship between the δ15N values of the cladoceran Daphnia magna and the C:N ratio of its diet.”
Weak cross‐species relationships between body size and trophic level belie powerful size‐based trophic structuring in fish communities (2001, background): “Gannes et al. 1997; Pinnegar & Polunin 1999; Ponsard & Averbuch 1999; Schoella 1999; Adams & Sterner 2000 ).”
ANTHROPOGENIC ENRICHMENT ALTERS A MARINE BENTHIC FOOD WEB (2005, methodology): “…corrections were used because C:N ratio of diets as well as other sources of variation may yield important differences in d15N fractionation although the exact mechanism of this variation and the direction of such change remains unclear (Adams and Sterner 2000, Vanderklift and Ponsard 2003).”
Biomass-Dependent Diet Shifts in Omnivorous Gizzard Shad: Implications for Growth, Food Web, and Ecosystem Effects (2002, background): “The 15N enrichment with each trophic level can be influenced by the C:N ratio of food items (Adams and Sterner 2000), nutritional stress (Hobson et al. 1993), selective feeding or assimilation (Mundahl and Wissing 1988; Smoot 1999), or the deriving of C primarily from one food source and N…”
TEMPORAL AND SPATIAL VARIATION TO ANT OMNIVORY IN PINE FORESTS (2005, background): “3), and the imbalance between metabolic needs and nutrient availability for aphids may reduce nitrogen fractionation (Scrimgeour et al. 1995, Yoneyama et al. 1997, Oelbermann and Scheu 2002; but see Hobson et al. 1993, Webb et al. 1998, Adams and Sterner 2000, Vanderklift and Ponsard 2003).”
Using bioenergetics models to predict stable isotope ratios in fishes (2002, background): “…set at 3.4‰ (±0.3) and 0.9‰ (±1.1), respectively (Vander Zanden et al. 1997; M.J. Vander Zanden, Center for Limnology, University of Wisconsin– Madison, personal communication), although we recognize that the magnitudes of fractionations are still a topic of debate (e.g., Adams and Sterner 2000).”
The role of sewage in a large river food web (2003, background): “and thus are all likely to have trophic fractionation shifts of about +2‰ (Adams and Sterner 2000).”
