Article Title: Integrating isotopic and nutritional niches reveals multiple dimensions of individual diet specialisation in a marine apex predator

doi: 10.1111/1365-2656.13852

Figure Lengend Snippet: Posterior mean cosine similarities (c‐index) between individual white sharks and the overall population based on modelled prey proportions (c‐index prey , p‐space) and nutrient intakes (c‐index nutrients , N‐space) under the TEF C scenario. Marginal boxplots compare variation in c‐index prey (top) and c‐index nutrients (right) among small (~1.50 m PCL, n = 6) and large (~2.25 m PCL, n = 6) size classes. The predicted relationship (shading = 95% confidence intervals) between the c‐index prey and c‐index nutrients was not significant (beta GLM, p = 0.061) but is shown to illustrate the deviation of some individuals (e.g. ws1, ws11) from the expected positive relationship.

Article Snippet: Macronutrient compositions (wet mass % water (%W), lipid (%L), protein (%P); carbohydrates excluded as they are negligible in most marine prey; Craig et al., ) were obtained from the literature for prey species included in the source groupings (Table ; see Data Sources section; also see Grainger et al., ).

Figure Lengend Snippet: (a) Proportion‐based nutritional geometry framework model of the wet mass % of protein, lipid and water in prey sources (triangles) and diets (posterior mean ± SD) of individual white sharks (squares) and the overall population (black circle) under the TEF C scenario. (b) Mean ± SD nutrient intake for juvenile white sharks based on stomach contents (white circle, n = 40; Grainger et al., ) overlayed on mixing model estimates (grey squares = individuals, black circle = population) for comparison. (c) Mean ± 95% credible intervals (CI) of differences between nutrient intakes of each white shark (ind, ws1–ws12) and the overall population (pop, Δ ind‐pop ). The probabilities that ind < pop are displayed along the top of each plot for each nutritional variable. Differences were inferred for probabilities >0.95 (ind < pop) or <0.05 (ind > pop). Individual sharks are labelled and colour coded for sex and size as in other figures.
