Two sounds associated with spawning lake trout (Salvelinus namaycush) in lakes Huron and Champlain were characterized by comparing sound recordings with behavioral data collected using acoustic telemetry and video. These sounds were named “growls” and “snaps” and were heard on lake trout spawning reefs, but not on a nonspawning reef, and were more common at night than during the day. Growls also occurred more often during the spawning period than the prespawning period, while the trend for snaps was reversed. In a laboratory flume, sounds occurred when male lake trout were displaying spawning behaviors: growls when males were …
Condition-Dependent Auditory Processing In The Round Goby (Neogobius Melanostomus): Links To Sex, Reproductive Condition And Female Estrogen Levels, Jeffrey N. Zeyl, Oliver P. Love, Dennis M. Higgs
Condition-Dependent Auditory Processing In The Round Goby (Neogobius Melanostomus): Links To Sex, Reproductive Condition And Female Estrogen Levels, Jeffrey N. Zeyl, Oliver P. Love, Dennis M. Higgs
Integrative Biology Publications
Neural responses to sensory stimuli often differ between sexes, vary seasonally, and can be regulated by endocrine activity, but the ecological and physiological mechanisms driving such patterns are not well understood. The current study examined how auditory function in the round goby (Neogobius melanostomus), a vocal teleost, co-varied with sex, reproductive condition and female plasma 17β-estradiol level. Auditory evoked potentials were collected in response to tone pips (100-600 Hz) and a natural round goby pulse vocalization. Additionally, saccule hair cell densities were compared across reproductive groups. Auditory threshold was evaluated in terms of pressure and particle acceleration, and response amplitude …
