Figure 1.

Maximum likelihood relationships between hermit crab (Pagurus) density and the proportion of their diatom (Isthmia) resource remaining after 2 weeks in field-deployed containers. The relationship was fit by using a Weibull function (Eq. 1). (A) Diatoms distributed sparsely on host Odonthalia flocossa (<45 mg⋅cm⁻¹). (B) Diatoms distributed densely on their host (>70 mg⋅cm⁻¹). Circled points were considered outliers and were not used for model fitting.
