Abstract
Urinary signals play an important role in communication between the individuals of the same species. The present study observed the response of mature male and female Rattus rattus towards conspecific natural urine of the same and the opposite sex. Responses to urine signals were determined based on food consumption on the treated and untreated sides of the cage. Mature male rats consumed significantly more food when treated with the urine of grouped mature female rats and female rats in the oestrous, pro-oestrous, di-oestrous, metoestrous, and lactation stages, while significantly low food consumption was observed in male rats in response to the urine of individual and grouped mature male rats, indicating strong attraction to the urine of the opposite sex and strong repulsion towards urine of the same sex. Similar observations were confirmed in bi-choice and multichoice maze experiments. Male rats did not show any significant response towards the urine of pregnant females. Under simulated store conditions, repulsion towards urine of the same sex was shown up to six days of exposure while the attraction towards the urine of the opposite sex was shown up to three days of exposure. Under simulated field conditions, the repulsive effect towards urine of the same sex remained for 9-13 days and the attractant effect to the urine of the opposite sex remained for all 15 days of the experiment. The study thus indicates that the reproductive condition of rats influences the communicative signals they produce as well as their own responses to conspecific signals of the same and the opposite sex.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
