About the Cover
Cover:
Substrate-spawning, male midshipman fish acoustically court females to attract them to a nest and then fertilize their eggs, which are attached to the nest's rocky substrate by an adhesive disk at the bottom of the yolk sac. Shown here are embryos that will soon be free-swimming fry. Sisneros and Bass (pp. 3121-3131) now provide the first in vivo investigation of age-related changes in the encoding properties of individual, peripheral auditory afferents for any fish species. Like non-reproductive adults, the afferents of juveniles best encode the low-frequency components of midshipman vocalizations. Photograph by Margaret Marchaterre of Cornell University.
