Evoked Vocal Response of the Bullfrog

Evoked vocal response in male túngara frogs: pre-existing biases in male responses?

Female túngara frogs, Physalaemus pustulosus, are preferentially attracted to a whine-chuck advertisement call over a simple whine (Rand & Ryan 1981, Zeitschrift für Tierpsychologie, 57, 209-214). Females also show phonotactic preferences for the whine when a number of other heterospecific or artificial stimuli are added to it, and these calls tend to be as attractive to females as a whine-chuc...

Thresholds for Evoked Vocal Responses of Eupsophus Emiliopugini (amphibia, Leptodactylidae)

Thresholds for evoked advertisement calling for 18 males were measured in a temperate forest in southern Chile, in order to relate this behavior to the intensities of neighbors’ calls that males of this species encounter in nature. Stimuli used were bouts of natural single-note advertisement calls played back at increasing intensity in steps of 6–12 dB. Male frogs responded with single-note adv...

Evoked Vocal Responses Change with Experience in Male Physalaemus pustulosus

Song-evoked inhibition and its role in vocal plasticity

cell types, one that innervates the song motor nucleus RA, and the other that innervates the basal ganglia homologue area X. Area X, the thalamic nucleus DLM and the anterior telencephalic nucleus LMAN form the anterior forebrain pathway (AFP; gray), which is implicated in auditory feedback and song perception, and which is essential to audition-guided vocal plasticity in juvenile and adult bir...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
