Candidate models for describing variation in foraging niche of <i>Pygoscelis</i> penguins assessed by δ¹³C and δ¹⁵N stable isotope signatures.

<p>Models presented are those determined to be most parsimonious, as well as all models receiving ΔAICc values ≤2.</p><p>Abbreviations: ΔAICc = Akaike's Information Criterion corrected for small sample size, <i>w</i> = Akaike weight, <i>r</i>²mf = pseudo <i>r</i>² McFadden.
