| Abstract | Signal-generation behavior of Portia labiata, a web-invading araneophagic jumping spider (Salticidae), was investigated in the laboratory. Individuals derived from two habitats in the Philippines were compared: Los Baños, a low-elevation tropical rainforest site where prey (spider) diversity is especially high, and Sagada, a high-elevation pine-forest site where prey (spider) diversity is less. Maternal effects and variation in experience were minimized because all individuals tested were from laboratory rearing to second and third generation under standardized conditions. Individuals from both populations used a trial-and-error (generate-and-test) algorithm to derive appropriate aggressive-mimicry signals. However, in laboratory experiments, the Los Baños P. labiata relied on trial and error significantly more often than did the Sagada P. labiata. Selection pressures that may have been responsible for evolution of different levels of flexibility are considered, including the different arrays of prey to which the Los Baños and the Sagada P. labiata are exposed. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
