• Evaluating quantitative fatty acid signature analysis (QFASA) using harbour seals Phoca vitulina richardsi in captive feeding studies (2008, background): “There is also debate as to how to enumerate recovered hard parts and subsequently reconstruct past diet (Laake et al. 2002, Tollit et al. 2003, Trites & Joy 2005).”
• A comparison and critique of different scat‐analysis methods for determining carnivore diet (2011, background): “Our sample sizes of n > 130 were above those generally assumed to be statistically necessary to describe a carnivore’s diet adequately (Trites & Joy 2005).”
• Harbor Seal Diet in Northern Puget Sound: Implications for the Recovery of Depressed Fish Stocks (2012, methodology): “A total of 2 or 3 collection trips were conducted each season, with a target sample size of 60 scats per season per region as recommended by Trites & Joy (2005).”
• Harbour seals target juvenile salmon of conservation concern (2017, methodology): “Sampling was stratified by collection site, year (2012, 2013), and season (spring: April–July; fall: August–November), targeting a total of 70 seal scat samples per stratum (Trites and Joy 2005).”
• The diet of feral cats on islands: a review and a call for more studies (2011, background): “A minimum size of *100 scats is considered necessary to identify principal prey remains occurring in 5% of scats and *100 samples is also required when comparing diets to distinguish moderate effects over time or between areas (Trites and Joy 2005).”
• Diet and prey profiles of three sympatric large carnivores in Bandipur Tiger Reserve, India (2007, methodology): “Furthermore, advanced analytic methods (Floyd, Mech & Jordan, 1978; Ackerman, Lindzey & Hernker, 1984; Reynolds & Aebischer, 1991; Trites & Joy, 2005) can be applied to such scat data to obtain accurate prey profiles.”
