Gut contents by fraction of total individuals and fraction of occurrence for 28 chum salmon fry.

<p>Shown is the taxa and life stage.</p

Carbon (δ¹³C) and nitrogen (δ¹⁵N) values for chum salmon fry and all prey taxa samples collected in the study.

<p>Habitat associations for the potential prey taxa are denoted by shaded circles or triangles: 1) white circles = supralittoral, 2) grey circles = high-intertidal/beach wrack, 3) black circles = mid-intertidal and 4) black triangles = low-intertidal. Chum salmon fry = open squares.</p

Stable isotope values of carbon (δ¹³C) and nitrogen (δ¹⁵N) for primary producers.

<p>Terrestrial vegetation was collected in the supralittoral and macroalgae was collected in the intertidal. Shown are common names and species names, number of samples (n), and sample δ¹³C and δ¹⁵N.</p

Stable isotope values of carbon (δ¹³C) and nitrogen (δ¹⁵N) and proportion of terrestrially derived carbon (TC) for consumers (invertebrates, fish).

<p>Shown are values for taxa by habitat (supralittoral, high-intertidal, mid-intertidal, low-intertidal) and common name/taxa and species name. Shown are the number of samples(n), the mean and standard deviation (SD) for δ¹³C and δ¹⁵N, the proportion of TC (%) including the mean, standard error (SE), and upper (U) and lower (L) 95 percentile confidence limits of TC calculated using the mixing model (Phillips and Gregg 2001). For chum salmon fry the minimum and maximum values of δ¹³C, δ¹⁵N, and TC are also shown.</p

Carbon (δ¹³C) and nitrogen (δ¹⁵N) values of prey taxa in supralittoral, beach wrack, mid-intertidal and low-intertidal zones.

<p>Lines show taxa collected in more than two zones: Acariformes (hatched line), Diptera (dotted line), and Amphipoda (solid line). Values in brackets represent the fraction of terrestrially derived carbon (TC).</p
