call that a male frog is tolerant of is known as the aggressive threshold. When this threshold is reached, a male frog will use a different call known as an aggressive call to initiate male-male conflict or intolerance. Advertisement and aggressive calls both consist of an introductory note ending with a wide range of a number of clicks, and multiple notes and patterns.Opposed to advertisement calls, aggression calls are characterized by a higher rate of repetition and longer timed calls. Male/male Interactions In opposition to most frog chorus species, D. ebraccatus chorus groups produce far-range aggressive calls more frequently than close-range. The higher proportion and number of far-range aggression calls causes D. ebraccatus males to be influenced by various surrounding calls in chorus groups instead of just calls from individual frogs. This influence from other males forces these male frogs to constantly adjust their calls accordingly. Generally, male frogs will respond to 2–4 Hz calls with synchronous advertisement calls. On the flip side, males will produce alternating advertisement calls or an initial delayed aggressive call when responding to a call that is 100 dB or more. For aggressive calls, long calls are utilized for close interactions and physical altercations. During close interactions in which a male frog attacks another, they tussle with each other while still exchanging long duration calls. These physical alterations usually only last one minute unless they remain in close contact and will sometimes continue. On the other hand, short calls are utilized during far-range interactions. Female/Male Interactions Mate Choice Call timing plays a significant role in female D. ebraccatus mating choice. Simultaneous male advertisement calling produces less reproductive success for males in close proximity. A male that starts its calls later is the preferred mating choice because females seem to prefer calls that end last. Click notes at the end of the late advertisement call may be one reason why females prefer the late call since the clicking of the lead call is blocked by the late call. The timing of male calls only depends on the call they produce and not the ones they hear. D. ebraccatus males show more synchrony, or overlapping calls, when producing advertisement calls and prefer to alternate with other calls when they produce aggressive calls. Calls with 150 to 200 millisecond introductory note durations produced synchronous response calls the most efficiently. Although females generally prefer the late call, they are
