Abstract
There is a growing list of marine invertebrate herbivores known to restrict their host choices to a subset of available species, yet the relative importance of the evolutionary forces that select for specialized feeding habits remain unclear. One such specialist is the gammaridean amphipod Peramphithoe tea (F. Ampithoidae) that restricts its distribution to the brown laminarian seaweed Egregia menziesii in Oregon. A field survey indicated that among available seaweeds in the low intertidal zone of Boiler Bay, Oregon, Egregia housed greater than 90% of P. tea individuals. A set of laboratory-based habitat and feeding choice assays revealed that this specialized host distribution is likely the consequence of choices made by adult P. tea. The restricted host choice is apparently maintained by at least two evolutionary forces. First, a juvenile performance assay indicates that both Egregia and the co-occurring seaweed Alaria marginata, provide high food quality relative to other seaweeds available in the low-intertidal zone. Second, a field transplantation experiment revealed that Egregia protects adult amphipods from becoming dislodged with wave energy more readily than did Alaria. Thus, Egregia’s value as good quality food and refuge from abiotic stress together explain the restricted host use of P. tea. A comparison with previous studies suggests that use of Egregia is not consistent across the geographic range of P. tea, suggesting the possibility that the host preferences of local populations may respond evolutionarily to geographic shifts in seaweed communities.
