| Abstract | The ecology and mating system of two populations of the peacock blenny Salaria pavo that have been reported to differ in sexual behaviour were studied. In the Gulf of Trieste, a northern Adriatic Sea population lives in rocky shores, whilst in the Ria Formosa, an Atlantic population inhabits a coastal lagoon with sandy barrier islands. In the Gulf of Trieste, nest availability was found to be higher and nest aggregation lower than in Ria Formosa. Nesting males courted females more and in higher proportion, and inversely, females directed less courtship displays towards nest holders in the Gulf of Trieste than in Ria Formosa. The relative frequency of small female-like males that reproduce by parasitically fertilizing eggs in the larger males’ nests was lower in the Gulf of Trieste population. This variation in the sexual behaviour of nesting males and females is likely to reflect a plastic behavioural response to the varying ecological conditions. The difference between populations in the relative frequency of parasitic males suggests that the male alternative reproductive tactics are condition-dependent. |

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.
