| Abstract | South Florida’s freshwaters are amongst the most invaded in the world with 34 naturalized fish species. How these non-natives affect the local native fish populations, however, is largely unknown. Native sunfish of the genus Lepomis are important as predators in structuring fish and invertebrate assemblages in the swamps and seasonal wet prairies of the Big Cypress Swamp and Florida Everglades. The spotted tilapia, Tilapia mariae, is a successful West African invader that exhibits territorial and spawning behavior that closely matches that of native Lepomis sunfishes. We tested the hypothesis that Lepomis sunfishes and T. mariae would compete when space was limiting. Additionally, we predicted that T. mariae, because of their aggressiveness, would be more successful in acquiring space. We collected juveniles of both groups from Big Cypress National Preserve, Everglades National Park, and the South Florida Water Management District canal system for laboratory trials in which likely competitive interactions were staged and observed. T. mariae were bolder and more aggressive than Lepomis sunfishes. T. mariae residents resisted all intruders whereas 30% of Lepomis sunfish residents were ejected. We surmise that these enhanced behaviors of T. mariae are an important component of their success in South Florida. The continued spread of T. mariae populations throughout South Florida into natural habitats suggests an increasing potential to affect the quality of spawning habitat available for Lepomis sunfishes and warrants a renewed focus on T. mariae as a non-native species of special concern. |

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.
