| Abstract | A common form of signal competition in acoustically chorusing animals involves the precise timing of calls relative to those of other nearby individuals. In this study, I present a detailed description of nonrandom timing of both advertisement and aggressive calls in males of the Neotropical treefrog Dendropsophus ebraccatus. I used playback tests to measure call delays for both advertisement and aggressive calls given in response to synthetic advertisement and aggressive call stimuli presented with either a fixed or random timing arrangement. Call delays for a given response call type were nonrandomly distributed and did not differ depending on the fixed or random periodicity of stimulus presentation or on the stimulus call type. In general, advertisement call responses overlapped the playback stimuli, while aggressive calls were given with a much longer delay and did not overlap the playback stimuli. A second test involved the presentation of low pulse number advertisement and aggressive call stimuli to determine if males were capable of nonrandom timing to truncated stimuli. These playbacks also assessed whether they responded more aggressively to truncated aggressive call stimuli. Males usually showed synchrony in response to truncated calls of both types, more commonly in response to truncated advertisement calls. There were no differences in aggressive responses to truncated advertisement or aggressive calls. Call delays appear to be a property solely of the type of call that the male produces, regardless of the kind of stimulus. Thus, there may be a conflict between the ability to discriminate between signals and the ability to rapidly respond to these signals with an appropriate call delay. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
