| Abstract | We investigate the relationship between habitat heterogeneity and morphological variation in the Caribbean coral species-complex, Madracis pharensis/decactis. This complex showed strong but incomplete morphospecies habitat-matching on a small spatial scale. We find that only one Madracis morphospecies dominates in environments consisting of either few vertical or few horizontal habitats, whereas in environments consisting of a mixture of horizontal and vertical habitats both morphospecies are common. We demonstrate that the observed patterns of morphospecies habitat-matching cannot be explained by a pure polyphenic model, where morphological variants are induced by a genotype-by-environment interaction at their settling site. Instead, we suggest that habitat-matching results in whole or in part from genetically predetermined factors. We present support for the hypothesis that this pattern of habitat-matching is due to habitat- and morphospecies-specific selective factors. Our study describes how a variable environmental factor, i.e. habitat distribution, has a non-linear effect on the spatial distribution of these morphospecies, thereby influencing the genetic organization of the Madracis coral complex at the ~+1–10 km spatial scale. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
