| Abstract | The cleaner fish Labroides dimidiatus affects the abundance of many fishes, including their juveniles, yet how they affect the post-settlement processes of conspecifics remains poorly known. Using a long-term experiment, where L. dimidiatus were regularly removed from seven patch reefs (removals) for 10 years or left undisturbed (controls) on nine, the effect of conspecifics’ presence on recently settled L. dimidiatus juveniles and the relationship between juvenile and adult abundance on control reefs were examined. Repeated sampling 4–40 months after manipulating L. dimidiatus revealed that the abundance of juveniles on removals, compared with controls reefs, was 72 % (95 % CI = 65–79 %) lower; this effect did not vary over time. Thus, decreased colonization was associated with resident conspecific absence and this effect was present after 4 months. Since other studies found 4 months of cleaner absence was too short to affect client abundance—a factor also known to enhance L. dimidiatus colonization—it was likely not involved here. Over 10 years, individual control reefs were almost always occupied by at least one adult (89–100 % of times sampled); but in summer, when L. dimidiatus colonization was highest, juvenile abundance was negatively related with adult abundance at one of two sites, with the expected number of juveniles decreasing by 67 % (95 % CI = 51–83 %) with each additional adult. This suggests a deleterious effect of adults on juveniles at one site, such as competition. Enhanced colonization of juveniles associated with adult presence may partly explain the relative permanence of fish cleaning stations. |

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.
