The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

From lavage to lipids: Estimating diets of seabirds (2012, unknown): “…technique provides this deep archival or retrospective capability and, of course, such methods can be applied to historic (Hobson & Montevecchi 1991, Hobson et al. 2004, Becker & Beissinger 2006, Emslie & Patterson 2007, Norris et al. 2007), as well as con temporary seabird trophic investigations.”
Population decline assessment, historical baselines, and conservation (2010, methodology): “Norris et al. (2007) correlated carbon and nitrogen isotopes in marbled murrelets with population sizes in existing colonies around the Pacific over 40 years and then used that correlation to estimate population trends in the 19th Century using isotope analysis from museum specimens of the species.”
A practical introduction to stable-isotope analysis for seabird biologists: Approaches, cautions and caveats (2009, background): “Based on changes in murrelet δ15N, it was estimated that Marbled Murrelets experienced a significant decrease in trophic position and proportion of fish over the preceding 100 years (Becker & Beissinger 2006, Norris et al. 2007).”
Using carbon and nitrogen isotopic values of body feathers to infer inter- and intra-individual variations of seabird feeding ecology during moult (2009, background): “Also, wing feathers from museum specimens are diYcult to procure, while body feathers are generally more readily obtained (Thompson et al. 1995; Norris et al. 2007).”
